Description

Wet vibrating wire dust removal fan for coal mine

Technical Field

The invention designs a dust removal device, in particular to a wet vibrating wire dust removal fan for a coal mine.

Background

Coal is used as a main energy source in China. With the strong support of national policy on coal mining industry, intelligent coal mining and clean and efficient excavation become the most important. With the technological progress in the coal mine industry and related industrial production, the productivity is greatly improved, but mining is often accompanied by a large amount of mine dust and coal dust, so that the working place is polluted, the human health is harmed, mechanical abrasion is accelerated, and the service life of a precision instrument is shortened. Practitioners often carry out remediation by wearing dust masks and dust-proof safety helmets, but the effect is very little, and the treatment is temporary and permanent. Especially in recent years, with the increasing number of pneumoconiosis and silicosis, the harm of dust is increasingly emphasized, so that the dust removing fan is extremely important and necessary for mining in the coal mine industry and dust removal in industrial production. However, most of coal mining processes in China adopt traditional dust removal modes, and the defects of low dust removal efficiency, influence on product quality, small application area and the like are usually caused. Most of dust production operating points still use the bag collector, and the filter bag of the dust collector uses the place restriction factor more, and has the shortcomings of easy jam, short service life, lower dust collection efficiency, complex replacement and the like. Therefore, the dust removal fan which can be widely used in different operation environments and has higher dust removal efficiency is designed, so that the cleanness of the working environment is maintained, and the health of practitioners is guaranteed, and great significance is achieved.

Some coal mines are designed to remove dust from the well. Most of the methods adopt a method of dedusting by spraying ventilation dedusting water or injecting coal bed water. However, these measures have certain disadvantages of ventilation and dust removal, and cannot control and capture dust at dust raising points, and the powdery material is sucked by mistake. The water spray dedusting has weak spray adhesiveness, and the nozzle is easy to block and rust. Coal seam water injection dust removal often influences the quality of coal mining, wastes time cost. Some mines also adopt a bag type dust removal fan to remove dust in the mines, however, the bag type dust removal fan is large in size, filter bags are easy to damage, and need to be replaced repeatedly, and manpower and material resources are consumed. But the use site thereof has more limiting factors. Complex underground coal mine movement and work are difficult to carry out. Nowadays, a novel foam dust removal device also exists, but the device is not mature enough, and the foaming rate of foam and the adhesion of dust become difficulties.

Disclosure of Invention

The invention aims to provide a wet vibrating wire dust removal fan for a coal mine. The water pump is connected by the connecting pipe, the water inlet valve is opened, and the water supply spraying system of the dust removal fan is connected. The negative pressure generated by the high-speed rotation of the cyclone sucks dust-containing air flow into the fan, and the first spraying water curtain sprays water mist which is mixed with the dust-containing air flow and enters a vibrating wire filter plate of the vibrating wire dust catcher. In front of the vibrating wire filter plate, water mist is sprayed out again by the sprayer, and the mixing and adsorption effects of the water curtain and the dust-containing air are further enhanced. When the mixture reaches the vibrating wire filter plate, the vibrating wire filter plate vibrates to drop along with the water flow, and meanwhile, dust accumulated on the vibrating wire filter plate is cleaned. The sewage is discharged from the sewage discharge hopper, and the purified air flow is discharged from the outlet, so that the aim of purifying the dust-containing air flow is fulfilled. The dust removal device effectively combines the prior ventilation dust removal and the water spray dust removal, and purifies the dust-containing air flow by combining the dust and the water spray and vibrating the vibrating wire dust catcher.
