Maintenance and maintenance of wet scrubber
Maintenance and maintenance of the scrubber: firstly check whether the packing layer and nozzles are blocked, secondly check whether the liquid level of the water tank is high enough to meet the liquid level requirements of the circulating pump, prevent the circulating pump from idling, and finally check the thickness of the sediment at the bottom of the spray tower water tank. The maintenance and maintenance of the leaching tower need to be cleaned in time This article mainly explains the maintenance and maintenance methods of the spray tower. The PP scrubber is a kind of wet waste gas treatment device. It adopts the counter-current principle. The waste gas passes through the spray tower and is dosed into the bottom water tank. The circulating fluid is sprayed on the packing layer. In contact with exhaust gas, neutralization and absorption reaction occurs to achieve the purpose of purifying exhaust gas. Then a complete set of wet scrubbers includes the tower body, water tank, packing layer, nozzle, demister layer, circulating pump, pipeline, pressure gauge, and feeder. Drainage pipes and the spray tower system are relatively negative pressure. During the operation, the maintenance and maintenance of the wet scrubber are equally important, which is directly related to the efficiency of waste gas treatment and the stability of the system. So what does the environmental protection engineering company need to do after the factory takes over a set of stable running spray tower systems? Xicheng Environmental Protection gives the following suggestions: The following items of the spray tower should be checked regularly during use. Whether the appearance of the PP scrubber has serious dirt, debris, etc.; Whether the multi-faceted hollow ball packing and nozzles in the PP scrubber are blocked; Whether the circulating spray pump is operating normally, observe the pressure gauge parameters; Whether the inside of the circulating water tank is blocked, observe the water level inside and outside the filter; Whether the sediment at the bottom of the water tank is too thick; Whether the screw fixing parts are loose or abnormal noise during operation; Regularly check and record the above content. If problems are found, it is recommended to enter the spray tower for maintenance and repair operations according to the following methods. Maintenance of PP scrubber Clean the surface of the wet scrubber and the surface of the water pump, fan, and ventilation pipe to prevent accumulation of debris; If it is found that the packing layer and nozzles in the wet scrubber are clogged, it is recommended to close the water supply ball valve of one spray layer to make the water pressure of the circulating water pump all pressurize the spray layer of the other layer. The ball is flushed and cleaned. After clearing the blockage, replace it with another spray layer for scouring and cleaning. If the blockage is serious and cannot be cleaned by its own water pressure, it can be solved by replacing the blocked spiral nozzle; If the water pump appears idling, abnormal noise, etc., it should be shut down for maintenance in time. The idling of the water pump is generally because the water level of the water tank is too low, and the water inlet ball valve should be opened to supplement the circulating water. For abnormal noise, loosening, etc., the specific cause should be found and repaired, and normal operation can be performed after recovery; Open the circulating water tank cover, you can see multiple filter orifice plates in the water tank. If you find that there are many stains on the top and the mesh is blocked, please take it out and scrub it with a brush, and then put it back in the tower. The too serious blockage should be cleaned with warm water or with chemicals; The sediment at the bottom of the spray tower should be cleaned regularly. Drain the sewage in the wet scrubber, open the transparent inspection hole, and enter the tower to clear the sediment out of the tower with tools, and then rinse the bottom and walls of the tower with clean water. If there are serious stains in the tower and the circulating water tank, use the corresponding agent to clean it; If the wet scrubber is loose, abnormal noise, etc. during the operation, the cause should be found in time, reinforced, or replaced by the corresponding parts.
Comparison of straight and corner sofas: which ones are better?
​Manufacturers usually offer sofas with straight and angled configurations. Many people may find their design quite understandable: straight models are stretched out in a straight line, and the second ones are placed in the corner of the room. But both varieties have many types, and it is difficult to choose the most suitable one. When thinking about whether to buy a straight or corner sofa, you need to consider its features, advantages and disadvantages. Direct models A straight sofa is stretched out in a line. Their main factor is the depth of the seat, which depends on whether there is a cot forming a sleeping place. In accordance with this, they can be equipped with a built-in folding bed (sofa bed) or without it. Models with clamshells often perform the function of a bed. When choosing such a product, you need to first determine its location, because when unfolded, it takes up quite a lot of space. This type of sofa is easy to turn into a comfortable bed, so there is no need to buy a regular bed. If it is to be used as a permanent sleeping place, it must have reliable sliding mechanisms. Furniture without a built-in clamshell is a compact solution compared to folding sofas. They are raised off the floor on their legs. The back of such a sofa is removed from its edge by almost 60 cm, which is on average equal to the length of the hip. These sofas are appropriate in the home living room and in offices. Also, straight models can be divided into two types, depending on where the sleeping area is located relative to the backrest: with a longitudinal berth; the sleeping place is perpendicular. Usually, the second option is characterized by a shorter length than the first. Sofas with a longitudinal sleeping area are made without cross seams. Interesting: How to Clean Velvet Sofa Methods? Corner services Sofas with a corner configuration in size can be compact, designed for three people, and for spacious rooms. The first type of corner sofas has a triple seat in the shape of the letter "G", and its protrusion is formed by an elongated couch. If such a small corner version is used for sleeping, then it must be equipped with a "dolphin" mechanism (all the pillows on the seat are involved in the transformation of the product into a sleeping place). Corner sofas for large spaces are full-fledged seating complexes made from parts of a modular system. You can find models for seats 3+3, 3+4 and more. Some sofas have such significant dimensions that their seats are curved twice, for example, in the shape of the letters P and S. They can have transformation functions and a sleeping place. These products are perfect for compact apartments, studio apartments, where you need to properly use the space. The corner of sofas of this type is formed using the "canape" design (standard or reduced version), as well as by means of a pedestal and attaching a chair module. Corner types can have identical sides or different lengths. U-shaped models are also available. Due to their practicality, modular corner sofas are the most popular. They are divided into two types: assembled from independent parts; with a strong connection of elements. Angular models that are rigidly connected will not be able to change frequently. If necessary, such a piece of furniture is disassembled and assembled in a different way, changing the location of the short and long parts. Sofas from independent sections allow you to change their design, type of placement and functional features more than once a day because their blocks are not connected to each other. But when choosing such a solution, you need to remember about its features: A sofa made from unrelated parts will cost more since it requires a lot of upholstery material, which determines the cost of the product.; Options with independent elements are usually chosen for large rooms, but they are not suitable for miniature rooms. In a room with a small area, it will be inconvenient to move modules, which will take up useful meters. Choosing a corner sofa Furniture design is very important, but you need to keep in mind its practical features. The fewer elements it contains in its frame, the better and more reliable it is in operation. It is desirable that the frame is made of beech, walnut or ash. Softwood products are more affordable, but not as durable and durable. The upholstery can be chosen according to the owner's taste. But wear-resistant materials will be preferred, for example, flock, natural or artificial leather, chenille, jacquard. The role of the filler together with the springs is usually played by a layer of felt, foam rubber or batting. In the case of foam rubber, the density should be at least 35 units. What's better for the kitchen? Often there are sofas in the kitchens. When choosing this piece of furniture, you need to take into account the size of the room, the style of the kitchen and personal preferences. A kitchen sofa will make the room cosier, and if it is equipped with a sleeping place, the kitchen will gain more functionality. Sliding kitchen sofas can have an angular or straight design. Straight allows you to place a maximum of three people on the sofa, and after unfolding, it moves forward. This type of furniture requires a spacious kitchen. Corner sofas are appropriate in small kitchens. They are characterized by a larger number of seats and the ability to unfold. At the same time, it increases in width, creating a comfortable sleeping place. Corner kitchen models can be made of different materials, such as leather, velour, suede, or jacquard. If it is used in the kitchen as a sleeping place, then synthetic materials are preferred: velour, flock, chenille. When choosing between a corner sofa and a straight sofa, you should take into account the layout of the room, its area and future purpose. Straight and angular options with the possibility of transformation will be the best solution for small rooms, a living room combined with a bedroom or dining room.
