Technical Introduction

1. Open circuit acid cleaning and hydraulic mechanical cleaning technology for ash discharge pipes in thermal power plants

Traditional chemical cleaning usually uses a closed loop cleaning process, which is not thorough in scale removal, requires a large amount of piping work, takes a long engineering time, and has a high cost. Based on our long-term accumulated experience in cleaning ash pipes in power plants, our company has invented a hydraulic mechanical descaling device and an open-circuit acid cleaning construction process, greatly improving the cleaning technology of ash pipes in power plants.

Hydraulic mechanical descaling refers to the use of normal ash water as the power source to drive a specially designed descaling device, combined with an imported tracking and positioning device. By squeezing the blades on the descaling device, the scale is peeled off and transported out. Cleaning and descaling is safe, pollution-free, and extremely low-cost.

Open circuit acid cleaning is a non-stop chemical cleaning and descaling method that utilizes the high flow rate of the ash pump, the strong scale dissolving ability of hydrochloric acid, and the CO2 small bubbles generated by the reaction to loosen, peel off, and aid in the dissolution of dirt, greatly improving the efficiency of acid utilization. It has the advantages of thorough descaling, no air bag phenomenon, short construction period, simple construction, and safety and reliability.

Kenchuang Company closely combines open-circuit acid cleaning and hydraulic mechanical scaling, fully leveraging their respective technical advantages to fully meet the needs of users in different situations.

2. Spray chemical cleaning technology

When cleaning towers and tanks with large volumes, Kenchuang Company's technical personnel have created a relatively complete and mature spray chemical cleaning method after years of cleaning practice and summary. The principle of spray cleaning is to use the pressure of water flow to evenly spray the cleaning solution towards the top and wall of the container through the sprayer during the cleaning process. By utilizing the splashing and wetting effects of a fluid with a certain flow rate when colliding with the wall, a ring is formed on the tank wall and top. Then, under the action of gravity, the cleaning solution flows along the wall to the rest of the tank, making full contact with all surface machines to achieve the purpose of cleaning.

Technical features:

① Significantly reduce cleaning costs

② Reduce labor intensity

③ Save cleaning time

④ Reduce the discharge of waste liquid

3. PIG pipeline cleaning technology

The PIG pipeline cleaning technology mainly relies on back pressure as the power to push the thruster (PIG) forward inside the pipeline, thereby removing the dirt accumulated inside the pipeline from the outside.

The PIG cleaning system consists of PIG, PIG transmitter
