Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coal dust suppression technology, specifically a spray dust suppression device. Background Technology
[0002] In the coal mining and coal chemical industries, coal crushing and screening processes are crucial. Because coal is buried underground for extended periods, coal seams form under surface pressure and temperature. Once exposed to normal temperature and pressure, these seams rapidly form invisible dust particles (2.5μm-50μm) and larger particles (50μm and above) that adhere to the coal surface. Dust generated during coal crushing and screening can remain suspended in the air for extended periods. These dust particles are not only small but also oily and have strong adhesion. Conventional dust suppression methods cannot fundamentally solve the problem, placing significant environmental pressure on enterprises and causing substantial harm to the environment and human health. Dust is highly hazardous to equipment; flash explosions and secondary dust explosions pose a serious threat to personal safety and equipment safety. Summary of the Invention
[0003] To address the aforementioned problems, specifically those raised in the background section, this utility model proposes a spray dust suppression device, the specific technical solution of which is as follows:
[0004] A dust suppression spray device includes a water storage tank 1, a dust suppressant tank 2 fixedly connected to one end of the upper part of the water storage tank 1, a water pump 3 arranged near the front of the bottom of the water storage tank 1, water outlet pipes 10 connected to both sides of the lower end of the water pump 3, the water outlet pipe 10 on the side closer to the water storage tank 1 is connected to the top of the water storage tank 1 through a dust suppressant pipe 4, and the water outlet pipe 10 on the side away from the water storage tank 1 is connected to the top of a booster tank 9, and the bottom of the booster tank 9 is connected to a discharge chute 21 through two water outlet pipes 11.
[0005] Preferably, in the dust suppression device, the pressurization tank 9 and the water pump 3 are installed in an underground water pump room 30. The water pump room 30 is a prefabricated steel structure building. The roof of the water pump room 30 is inclined. A door 31 is installed on the wall away from the water storage tank 1. Steps 41 are provided on the outside of the water pump room 30 from the door 31 to the ground.
[0006] Preferably, an electrically controlled valve 7 is installed on the water outlet pipe 10 at the end of the water pump 3 near the water storage tank 1, and a check valve 8 is installed on the water outlet pipe 10 at the end away from the water storage tank 1. A fixed level gauge 6 is installed at the front end of the dust suppressant pipe 4 near the water storage tank 1, and a flow regulating valve 5 is installed at the lowest end of the dust suppressant pipe 4.
[0007] Preferably, the dust suppressant in the dust suppressant tank 2 is mixed with water in a specific ratio through the regulating valve 5 and the electrically controlled valve 7.
[0008] Preferably, the water storage tank 1 and the dust suppressant tank 2 are positioned above the vertical water pump 3.
[0009] Preferably, the water storage tank 1 is a metal container with an anti-corrosion agent sprayed on its outer surface, and the dust suppressant bucket 2 is a plastic container.
[0010] The beneficial technical effects of this utility model are as follows: the dust suppressant tank outlet pipe is connected to the water outlet pipe on one side of the bottom of the water storage tank. The dust suppressant enters the main water pipe for mixing through the height difference pressure and the flow rate of the regulating valve. The mixed liquid is pumped into the pressure tank by a vertical water pump, which increases the outlet pressure of the mixed liquid and diverts it through a three-way pipe. The increased water pressure in the pipe makes the water mist sprayed from the nozzle more effective. The PLC controls the frequency converter to start the water pump motor and increase the water pressure. At the same time as the water pump motor is powered on and started, the electrically controlled valve on the dust suppressant pipeline opens. The dust suppressant is mixed with clean water through the regulating valve and the pipeline. The water is then pumped to the pressure tank, pipeline and nozzle to achieve the best dust suppression effect. Attached Figure Description

[0015] The liquid outlet pipeline connects the water outlet pipeline device at the bottom of the water storage tank and the pressurization tank device. There is one water storage tank and one dust suppressant tank, and the two containers are set one above the other. The water storage tank is buried 3 meters below the ground level, and the dust suppressant tank is fixed on the upper side of the water storage tank and heated and insulated.
[0016] The front end of the water storage tank is close to the pump room, and the water outlet pipe, dust suppressant pipe, and water pump are connected at the bottom of the tank.
