In recent years, chemical cleaning methods have been gradually extended, the use of chemical cleaning of boilers and heat transfer equipment, large scale has been adopted by people in many areas of the chemical cleaning is to start this regard, and in this regard has made great economic benefits for energy conservation have contributed to the great cause. 
 Sewer construction workload is generally greater, a wider work surface, the future is still one of the main cleaning area. At the same time there is a lot of chemical cleaning and potential market areas, namely hotels, restaurants, residential sewer pipe dredge, such cleaning is also a pressing social need. Currently a lot of reasons not spread, but this work unit, the effect is very significant, popular with users. I hope all regions, especially in large, medium and small cities of the chemical cleaning workers to enter the field, solve problems of urban life. Hotels, restaurants, residential and other buildings, all under the water of life after delivery with as many as ten years, ranging from a few years there will be jams (not including sewer use inadvertently block access to foreign bodies), to the people lives of great inconvenience, especially in the very particular about the high-rise buildings, the emergence of this phenomenon is very complicated thing. In many cities in recent years, these issues reflect a very strong, with the improvement of living standards and housing modernization, such problems will become more prominent. 
 Pipeline blockage problem there are two such reasons, one because sewage contains large amounts of calcium and magnesium salt and grease and other material easy to scale. The second reason is that these stains in the water and mixed with sediment, urine, or oil and other substances to make life easier for sewage water than life scale. Resulting in use of new building shortly after the pipeline began to reduce the cross-section, traffic began to decline, poor circulation, so the last pipe was completely blocked. Then we must take measures to clean up and clear. 
 Of course, the distribution of bending inside buildings, small or complex structure of the pipe to clear the clean-up is a very troublesome thing. It has been used manual or mechanical methods to replace all the pipes to clear the practice of doing so is time-consuming, labor-, material costs, and the results are not particularly good, and soon will plug so that the problem seriously. Chemical cleaning can solve this problem more successfully. 
 At present, some qualified hotels and restaurants have adopted the chemical cleaning methods, cleaning agent such good effect, by using the unit as well, especially the pain by grease clogging the unit. But for now, more units are still anxious for such issues, chemical cleaning workers to be propaganda, to solve the problem. Domestic water and sewer cleaning chemical cleaning boilers and other equipment have in common, but also has its own characteristics. 
 Pipeline dredge method and construction process 
 1. The washing object hotels, restaurants, residential sewer and bathroom equipment, nothing more than a bath, spray, tub and connecting pipes, etc.; toilet big toilet, urinal and connected piping; Kitchen pool, floor drain and the connection pipe connecting the outdoor water wells and their pipelines and so on. Cleaning, you should first figure out the ins and outs pipeline, and understand life, usage, congestion, buried and exposed portion of a building for damage and other issues. Of damaged equipment and piping must be replaced before cleaning. Equipment in the query pipeline at the same time, pay attention to the material, in addition to cast iron and ceramic, the system also what materials, cement and other construction materials if the equipment and piping, and system cleaning is best separated to avoid corrosion. 
 2 segments of the pipeline will need to be cleaned into a number of cleaning section, this work must be done before washing. Various buildings, the number of floors, unit numbers are not the same, sewer and equipment capacity are not the same. In order to facilitate pipeline dredge, generally divided into several small cleaning section, segmented approach is mainly based on sewer capacity, low floor for easy cleaning, and sub-possibilities. Generally a three-unit, four floors of a well. 
 3. Breach in pipe cleaning is an important part. First top-down blocked at the first segment, this segment is generally in the pipelines at the observation hole (hand holes) at, and then connected with the atmosphere through the mouth and in parallel with other pipeline through the port blocked , leaving only the section of the top two openings, a mouth to feed cleaning fluid, a port used to exclude air. Closure should be able to withstand at 1-2 kg / cm 2 pressure and to avoid cleaning, due to liquid column hydrostatic leaving Breach sabotage. If the valve at closure, it is best not rely entirely on the valve closure, because the valve, using the long and difficult locked, should take appropriate measures with the other closure. 
 4 leak closure after work, to conduct leak testing. Leak testing method is this: the paragraph from the left top of the liquid into the mouth to the Riga water, fill up the system and observe the water level is down, if down, find the leak and process the drain port, if maintained water level can be the next step. 
 5 cleaning from top to bottom according to paragraph by paragraph into several sections for cleaning, acid leak testing method with the same way as water, commonly used immersion cleaning. If the cleaning speed is too slow or stopped, not any dirt washed, may be appropriate to replace part of the cleaning liquid to continue cleaning until the wash. Wash the first paragraph, under the second paragraph of the Breach blocked, open the first paragraph of the closure, so that cleaning fluid into the second cleaning, if the cleaning is not enough concentration, can be taken to replace or replace all parts, until the wash . Third paragraph, fourth paragraph ... ... in turn. Several steps in the same unit cleaning methods, cleaning is completed should be placed in a unit plenty of water, open all the closure, allowing the system returned to normal. Domestic water than the boiler chemical cleaning sewer cleaning equipment is more complicated, but as long as those based on the actual situation of cleaning to take appropriate measures to develop a detailed cleaning program, cleaning is secure, look to the majority of workers in the field of chemical cleaning to enter.
