Ventilation device for confined space with water washing function

Abstract

A ventilating and ventilating device for a confined space with water washing function, the ventilating and ventilating device for a confined space comprises an air inlet pipe and an air exhaust pipe, one end of the air inlet pipe and the air exhaust pipe is installed into an underground air duct, and the ends are respectively installed with The air intake chamber and exhaust chamber; the other ends of the air inlet pipe and the exhaust pipe are respectively installed in the ventilation area, and the exhaust air chamber is installed on one end of the exhaust pipe installed in the ventilation area; the air inlet pipe and the exhaust pipe The air intake fan and the exhaust fan are respectively installed on the top, and the air intake fan and the exhaust fan are respectively used to form air convection in the air intake duct and the exhaust duct; separated by a grid. The ventilation area is also equipped with a water washing device, and a dust removal device is installed on the air inlet pipe. The brushing mechanism realizes the scrubbing and dredging of the grid, the first dust removal net and the second dust removal net.

Description

technical field [0001] The invention relates to ventilating equipment for underground mines and tunnels, in particular to a ventilating device for confined spaces with water washing function. Background technique [0002] In the design of underground ventilation, although there are dedicated air ducts for ventilation, this design can solve the ventilation problems of most roadways. However, for some newly developed mining areas and emergency refuge areas, due to the untimely layout of facilities or the design of refuge spaces, the ventilation in these areas will be seriously delayed or even not ventilated. However, there are many harmful gases in the underground, such as carbon monoxide, methane, sulfur dioxide, etc., and there are more germs. Therefore, in order to ensure the air circulation in this area, it is generally necessary to install a ventilation device for ventilating the enclosed space. Its principle is mainly to connect the air duct with this area through a ven...

Problems solved by technology

[0003] However, this type of confined space ventilation device generally simply reverses the air flow, and the underground dust, dust, etc. are relatively large, especially in the air duct, whose wind force can blow small stones, so solid debris blocks the ventilation pipe is commonplace

In order to ensure the normal operation of ventilation devices in confined spaces, it is generally necessary to regularly overhaul the air ducts, and because the ducts are easy to block, the frequency of overhauls has to be relatively high, sometimes more than three times a week

This obviously greatly increases manpower input, and it needs to be shut down during the maintenance process. Once shut down, the ventilation area must be shut down, which has a great impact on the mining progress
