Problems solved by technology

[0002] The hydrogen fluoride gas produced by the hydrofluoric acid reactor contains a lot of dust. A large amount of dust will accumulate on the inner wall of the gas guide box after the hydrogen fluoride gas passes through the gas guide box. Over time, the gas guide box will be blocked, making the hydrogen fluoride gas ineffective. transportation, and there is a safety hazard of harmful gas leakage
[0003] At present, the cleaning of the sediment in the gas guide box of the hydrofluoric acid reactor mainly relies on manual cleaning. Since the sediment contains viscous substances such as calcium sulfate, the manual cleaning is labor-intensive. Moreover, because hydrogen fluoride is a highly corrosive chemical substance, it is easy to cause safety hazards. Accidents that cause damage to businesses and employees

Embodiment Construction

[0016] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0017] The most critical idea of ​​the present invention is that the helical structure effectively reduces the space occupied by the slag removal device in the air guide box, ensures good gas circulation, and the helical structure has certain self-adaptability, which can improve the rotary slag removal. The stress of the belt during the process of scraping and conveying dust.

[0018] Please refer to figure 1 , a slag removal device for an air guide box, comprising a rotating slag removal belt arranged spirally along the gas conveying direction in the air guide box, and there is a gap between the rotating slag removal belt and the inner wall of the air guide box.

[0019] From the above description, it can be seen that the beneficial effect of the present inven...

Abstract

The invention relates to the technical field of chemical industry, in particular to a deslagging device for a gas guide box. The deslagging device comprises a rotary deslagging belt which is spirallyarranged in the gas guide box in the gas conveying direction, and a gap is reserved between the rotary deslagging belt and the inner wall of the gas guide box. The deslagging device for the gas guidebox is simple and reliable in structure, capable of automatically removing slag in the gas guide box, reliable in sealing and free of leakage of harmful gases such as hydrogen fluoride, reduces the shutdown maintenance frequency, shortens the shutdown maintenance time, prolongs the service life of equipment, reduces the labor intensity, improves the safety of deslagging operation, achieves automatic operation of equipment, and improves hydrofluoric acid yield.

Background technique [0002] The hydrogen fluoride gas produced by the hydrofluoric acid reactor contains a lot of dust. A large amount of dust will accumulate on the inner wall of the gas guide box after the hydrogen fluoride gas passes through the gas guide box. Over time, the gas guide box will be blocked, making the hydrogen fluoride gas ineffective. transmission, and there is a safety hazard of harmful gas leakage. [0003] At present, the cleaning of the sediment in the gas guide box of the hydrofluoric acid reactor mainly relies on manual cleaning. Since the sediment contains viscous substances such as calcium sulfate, the manual cleaning is labor-intensive. Moreover, because hydrogen fluoride is a highly corrosive chemical substance, it is easy to cause safety hazards. Accidents, causing damage to enterprises and e...
