Description

Technical Field

[0001] The utility model relates to the technical field of mud discharge, and more specifically, to a periodic mud discharge device for a gasifier heat exchanger. Background Art

[0002] The primary purpose of a regular desludging system for a gasifier heat exchanger is to remove accumulated sludge and impurities from the heat exchanger. This is crucial for maintaining equipment performance. Sludge and impurities can clog the heat exchanger's pipes and channels, reducing heat exchange efficiency and impacting the gasifier's overall performance. Regular desludging ensures internal cleanliness and maintains proper heat exchange function.

[0003] Patent publication number CN110115147A discloses a mud discharge device. This technology uses a mud guard and a drum to quickly drain mud and shallow water from loamy soil, exposing the soil layer where water chestnuts grow. This device is simple in structure, low in cost, and long in service life. However, this device has the following problems:

[0004] During the regular sludge removal process of the gasifier heat exchanger, although the sludge inside the gasifier heat exchanger can be cleaned, it is difficult to quickly guide the cleaning during the internal cleaning process, which results in not only poor cleaning effect of the sludge inside the gasifier heat exchanger, but also time-consuming and labor-intensive cleaning.

The guide head guides and pulls the guide column, and the pull column drives the connecting column to move rightward. The support rod supports the cleaning scraper ring. The cleaning scraper ring and the scraper ring can fit the inner wall of the gasifier heat exchanger pipe to move rightward for cleaning, which makes the mud removal effect of the gasifier heat exchanger pipe better, not only improving the cleaning effect, but also saving time and effort.

[0012] 2. The utility model uses a limited pulling mechanism, with two hooks hung on both sides of the pulling ring, and the other two hooks hung in the two pulling grooves inside the two grooves. The sliding column drives the pulling ring to move right and pull, while the groove drives the arc plate to move right and pull, and the rope body drives the connecting rope to move right and pull, thereby enabling the cleaning scraper ring and the scraper ring to clean the mud in the gasifier heat exchanger pipeline.
