Ventilation device for confined space

Abstract

A ventilation device for a confined space, the ventilation 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 loaded into an underground air duct, and the ends are respectively equipped with an air inlet chamber, Exhaust bin; the other ends of the air inlet duct and the exhaust duct are respectively installed in the ventilation area, and an exhaust bin is installed on one end of the exhaust duct into the ventilation area; the air inlet duct and the exhaust duct are respectively installed with Air intake fan, exhaust fan, air intake fan, and exhaust fan are used to form air convection in the air intake duct and exhaust duct respectively; the upper ends of the air intake bin, exhaust bin, and exhaust bin are separated by grids . 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 present invention relates to a ventilation apparatus such as a downhole, a tunnel, and more particularly to a closed space ventilation device.Background technique[0002]In the design of the underground ventilation, although there is a special airway to ventilate, this design can solve the ventilation problem of most of the roadways. However, for some newly developed harvesters, emergency refuge zones, etc., this part of the region ventilation will be severely lagged after or even ventilation because the facility arrangement is not timely or for the space design of the refuge. However, the harmful gases under the well, such as carbon monoxide, methane, sulfur dioxide, etc., more pathogen, so in order to ensure the flow of air in this area, it is generally necessary to add a ventilation and closed space ventilation device. The principle is mainly to connect the airway to this area through the ventilation fan or pumping, the suction device, thereby pumping the a...

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
