Passive high-efficiency purification air-conditioning device for coal mine rescue cabin

Abstract

A passive high-efficiency purifying and air conditioning device for a coal mine escape capsule belongs to the field of air purifying equipment for coal mine escape capsules. The passive high-efficiency purifying and air conditioning device comprises a purifying-air conditioning unit (7) connected with an air pipe (9), and an air purifying box (12), and is characterized in that a centrifugal fan (11) and an evaporator (8) are arranged in the purifying and air conditioning unit (7), the centrifugal fan (11) is connected with a coaxial pneumatic motor (10) of the centrifugal fan; a cross flow fan (14) and a filter layer are arranged in the air purifying box (12), the cross flow fan (14) is connected with a coaxial pneumatic motor (13) of the cross flow fan, the filter layer is arranged between an air inlet and the air pipe (9); and an air supply pipeline which takes liquid carbon dioxide as a refrigerant and a control valve are arranged. Due to the integral design, the following conditions can be realized: a device can operate without power supply, is anti-explosion and does not need combustion supporting; the air can be purified with high efficiency; the liquid carbon dioxide refrigeration and high-efficiency air purification can be realized integrally; and the pollution does not exist, the environment is protected, and the secondary damage on people in the pit and the environment can not be caused.

Description

technical field [0001] The invention provides a passive high-efficiency purification air-conditioning device for a coal mine rescue cabin, which belongs to the coal mine rescue and danger avoidance technology, and is mainly used in the fields of coal mine rescue cabins and refuge chambers.

The coal mine rescue cabin has active electric refrigeration and air conditioning, which has large vibration and noise, and th...

AI Technical Summary

Problems solved by technology

[0003] Coal mine rescue cabin has active electric refrigeration and air conditioning, which has high maintenance costs, many maintenance cycles, and the quality of training technicians

The active electric refrigeration air conditioner in the coal mine rescue cabin has large vibration and noise, and the underground condenser is prone to dust blockage, and the operation cycle is long

Carbon dioxide plus battery refrigeration air conditioner has the problem that the DC explosion-proof motor fan battery cannot pass the test, especially the battery air conditioner, which has low power and short time, and cannot meet the requirements

Its shortcomings are: 1. The cooling air output is provided by an air motor, and the air output is small; 2. There is no filter device, which may easily cause cloudy air in the refuge cabin; 3. The refrigerant is liquid nitrogen, and the air conditioning is inconvenient
