Coal shed dust reduction explosion-proof fog cannon machine is a kind of environmental protection equipment widely used in the coal industry, mainly used to reduce the dust concentration in the coal shed, improve the working environment, and at the same time have explosion-proof functions to ensure safe production. This article will introduce in detail the composition and working principle of the coal shed dust reduction and explosion-proof fog cannon machine.
1. Composition. The coal shed dust reduction explosion-proof fog cannon machine is composed of the following parts:
1.Nozzle: The nozzle is one of the important parts of the fog cannon machine, and its function is to spray water or water mist out. The specification, number and arrangement of the nozzles directly affect the spraying effect of the fog cannon machine. According to different needs, different specifications of nozzles can be selected to achieve the best spray effect.
2.Pumping station: The pumping station is an important part of the fog cannon machine, and its role is to provide enough water pressure and water volume to enable the nozzle to work properly. In order to ensure the spray effect, it is necessary to select the right pumping station to ensure that the water pressure and water volume meet the requirements.
3.Control system: The control system is the "brain" of the fog cannon machine, which is responsible for controlling the start, stop, spraying time and spraying method of the fog cannon machine. Through the control system, the remote control of the fog cannon machine can be realized, which is convenient for operation and management.
4.Bracket: The bracket is the supporting structure of the fog cannon machine, which is used to fix and support the entire fog cannon machine. The bracket must have sufficient strength and stability to ensure that the fog cannon machine can remain stable while working.
5.Explosion-proof device: Because there may be flammable and explosive gases in the coal shed, the fog cannon machine needs to be equipped with explosion-proof devices to ensure safe production. The function of the explosion-proof device is to effectively reduce the impact on the fog cannon machine itself and the surrounding environment when it occurs.
Second, the working principle.
The working principle of the coal shed dust reduction and explosion-proof fog cannon machine mainly involves the following links:
1.Nozzle spraying: Control the nozzle to spray according to the set spraying method and time through the control system. During the spraying process, the water mist collides with the dust particles in the air and adsorbs, so that the dust particles gradually settle down.
2.Wind flow control: The wind flow control technology is used to guide the wind flow in the coal shed to the vicinity of the fog cannon machine, so that the dust particles move in the direction of the fog cannon machine under the action of the wind flow, and the settlement effect is improved.
3.Air pressure adjustment: By adjusting the pressure of the pumping station, the size and speed of the water mist particles sprayed by the nozzle are controlled to achieve the best dust reduction effect. At the same time, according to the actual needs, the spray pressure and flow rate can be adjusted to meet the dust reduction needs under different working conditions.
4.Automatic control: remote control of the fog cannon machine through the control system to achieve automatic spraying. The control system can automatically adjust the spraying time and mode according to parameters such as dust concentration to improve the efficiency of dust reduction.
5.Explosion-proof function: The explosion-proof device can be automatically activated in the event of **, which can quickly reduce the temperature and pressure in the coal shed, and at the same time cut off the power supply and gas source to prevent the situation from expanding. In addition, the explosion-proof device is able to overload the fog cannon machine, ensuring that the equipment will not be damaged in extreme conditions.
Through the above analysis, it can be seen that the coal shed dust reduction and explosion-proof fog cannon machine is a kind of environmental protection equipment with high technical content and wide application. In the coal industry and other fields with serious dust pollution, the use of this equipment can effectively reduce the dust concentration, improve the working environment, and ensure safe production. In the future, with the improvement of environmental protection requirements and the development of technology, the coal shed dust reduction and explosion-proof fog cannon machine will be more widely used and promoted.
