What is an explosion-proof fog cannon?

2022-08-26


Many people may not be unfamiliar with fog cannons. After all, with the strengthening of environmental protection work in various places, fog cannons, such as environmental protection dust removal equipment, can basically be seen in many places. But do you really know about explosion-proof fog cannons?


Usually, the fog cannon is mainly composed of several functional modules such as "jet spray system, waterway and atomization system, circuit control system, automatic steering device, pitch angle adjustment hydraulic system, rotating support and base"; Vehicle-mounted mobile fog cannons and tower-mounted fog cannons will basically not deviate from this basic category.





First, what is an explosion-proof fog cannon
To understand what is an explosion-proof fog cannon, first of all, we need to understand what is explosion-proof. In fact, the explosion-proof mentioned here is mainly to prevent explosions.

Anyone who has studied physical chemistry knows that if rapid combustion occurs in a limited space, an explosion will occur. The explosion can be caused by the combustion of gas, or by the combustion of liquid and dust solids; that is to say, as long as there is a possibility of combustion, an explosion may occur.

Second, why use explosion-proof fog cannon
In real life, such as coal plants, power plants and other factories and mines, due to the special environment, all production equipment needs to avoid sparks; however, due to the needs of environmental protection work in various places or for the purpose of dust and dust removal, it It is inevitable to use fog cannon equipment to achieve the effect of environmental protection and dust reduction.

However, as a kind of mechanical equipment, there are inevitably electronic circuits and other electronic components on the fog cannon, such as "electronic control system, steering system" and so on. At the same time, due to the needs of spraying, there is a high-speed fan impeller in the barrel of the fog cannon; in some cases, the high-speed operation of the impeller may also cause high temperature and even sparks.

Therefore, considering various factors, the fog cannon equipment that it needs to use must also achieve the effect of explosion protection while reducing dust. Otherwise, any security incident that occurs cannot be easily borne by anyone. The explosion-proof fog cannon, because of its comprehensive characteristics, will not spark in the working environment; this indirectly achieves the effect of explosion-proof.




Third, the structure of explosion-proof fog cannon
In fact, for Henan Shuangxin, all parts of its explosion-proof fog cannon equipment, including "air ducts, water pumps, hydraulic motors, control cabinets, and solenoid valves", are required to achieve explosion-proof and spark-free effects.

At the same time, the impeller, including the fog cannon, is also machined from aluminum alloy to prevent sparks during operation. The motor is isolated explosion-proof motor.

Fourth, the status quo of the fog cannon industry
At present, there is no unified national standard for fog cannons; however, the fog cannon equipment independently developed by Henan Shuangxin has obtained a number of national technical patents. Users can customize fog cannon dust suppression equipment with various ranges of "30 meters - 120 meters" according to actual needs; there are also ultra-long-range fog cannons of 130 meters and 150 meters!
