Overview of dust removal guns

Coal field spray water mist dust removal system as an example to outline the composition and performance of the dust removal gun, coal field spray water mist dust removal is mainly through the sprinkler gun high-pressure sprinkling water to play the role of coal field dust suppression, coal field spray dust reduction management. Coal field water mist dust removal is divided into coal field spraying, transfer station dust removal and car unloading coal ditch dust removal.

Coal field spray water mist dust removal system as an example to outline the composition and performance of the dust removal gun, coal field spray water mist dust removal is mainly through the sprinkler gun high-pressure sprinkling water to play the role of coal field dust suppression, coal field spray dust reduction management. Coal field water mist dust removal is divided into coal field spraying, transfer station dust removal and car unloading coal ditch dust removal. The following details the composition and principle of the dust removal spray gun in the coal yard. First, the main composition of the dust removal gun: the system is mainly composed of water pipeline and control system, which has a water pipeline, gun, solenoid valve (with built-in filter), automatic water relief valve, manual ball valve, and control cabinet. Solenoid valve on the reserved automatic drain valve interface, the use of the U.S. NELSON (U.S. Nelson) automatic drain valve, automatic drainage of water stored above the solenoid valve, as far as possible to protect the gun in the cold season is not frozen. Dust gun in the solenoid valve built-in filter, with self-cleaning function. Solenoid valve itself also has an internal water release switch, external water release switch, can be operated in place. Second, the principle of the dust gun and the way: cyclic spraying, simultaneous spraying, timed spraying, spot spraying and on-site manual spraying. Cyclic spraying means that each spray gun according to the set program automatically work in turn for a period of time, time adjustable. Simultaneous spraying means that all guns work at the same time, so that the entire coal (material) field is covered with water at the same time, and this control method has high requirements for the head of the pump and the flow of water, while the practicality of this method is not great according to the actual situation. Timed spraying is an automatic work mode, mainly refers to the automatic start and stop gun work according to the program pre-set time. Point-action spraying is a manual way to start and stop the work of the gun, for a common way of working, according to the site conditions at will to start and stop the dust gun work. Suitable for most occasions, but also more economical and effective way of working.
