Spray type dust fall device

Abstract

The invention discloses a spray type dust fall device. The spray type dust fall device comprises a water storage device, a water pump, a rotary device and a spraying device. A water outlet of the water storage device is connected with a water inlet of the water pump. A water outlet of the water pump is connected with a water inlet of the spraying device. The water pressure at the water outlet of the water pump ranges from 4MPa to 15MPa. The spraying device comprises a spray head body, a short-range spray nozzle and a remote spray nozzle. The short-range spray nozzle and the remote spray nozzleare fixed to the front end of the spray head body from top to bottom in sequence. The rotary device is in rigid connection with the spray head body and is used to enable the front end of the spray head body to horizontally rotate clockwise or anticlockwise. According to the spray type dust fall device, because the water storage device, the water pump, an action mechanism and the spraying device are used in cooperation, sprayed water mist is uniform in mist droplets, large in density and broad in coverage area; and the spray type dust fall device is especially suitable for water mist spray ofa wide range.

Description

technical field [0001] The invention belongs to the field of dust suppression equipment, and more specifically relates to a spray type dust suppression device. Background technique [0002] At present, industrial and mining enterprises will inevitably produce some dust during production operations. According to the particle size of dust particles, these dusts can be divided into coarse dust (particle size greater than 40 μm, which is easy to settle in the air), fine dust (particle size is 10 μm ~ 40 μm, accelerated settlement in still air), fine dust ( The particle size is 0.25μm~100μm, which settles at a uniform velocity in still air), ultra-fine dust (particle size is less than 0.25μm, and it is dispersed in the air). Among these dusts, some are suspended in the air, which is called floating dust, and some are deposited on the ground, which is called falling dust. Floating and falling dust can be transformed into each other in different environments. Among them, the time...

Problems solved by technology

However, the rated pressure of this high-pressure water pump is too high (more than 20MPa), and the droplet diameter of the internal water column is too small (1 μm to 5 μm) after two mixing injections, the dust reduction effect is not good, and the coverage radius is small, so it is not suitable for large-scale outdoor movement.
