Abstract
The invention relates to a special roof type evaporator for coal mine methane. The special roof type evaporator for the coal mine methane is that a mine ventilator is in sealing communication with a coal mine methane diffusion column through an air duct; an upper end outlet of the coal mine methane diffusion column is in sealing fixing with a lower end inlet of an evaporator; the evaporator body is in sealing communication with a channel of a coal mine methane source heat pump through a medium conveying pipe and a medium returning pipe; another channel of the coal mine methane source heat pump is in sealing communication with a user through a water inlet/ outlet pipe water pump. The special roof type evaporator for the coal mine methane is simple in structure, small in resistance, high in heat exchange efficiency, effectively overcomes the influences of high humidity, large air flow, large dust quantity and small pressure difference of a coal mine on the heat exchange efficiency, and is long in service life and convenient to maintain.
Description
Technical field
The present invention relates to a kind of low heat value energy extraction equipment, be mainly used for extracting the low heat value energy in mine air-lack.
Background technology
When winter air temperature is very low, more than 2 DEG C are heated at air intake mine, under input well, after country rock heating, machinery heating, the heat of oxidation, crack water and channel water, rock crushing and hot body metabolism temperature after heating reach 18 ~ 22 DEG C, go out from air draft well array, the wind of discharging has contained abundant geothermal energy resources.But all waste at present.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of roof type mine air-lack special evaporator, its structure is simple, resistance is little, and heat exchange efficiency is high, effectively can overcome the weary high humidity of mine, air quantity is large, Dust Capacity is large, the impact of the little heat exchanging efficiency of pressure reduction, long service life, is convenient to safeguard.
The present invention solves the technical scheme that its technical problem takes: Mine Ventilator to be sealed with the lower end of weary wind retention tower by mine air channel and communicates, the upper end outlet of weary wind retention tower and the lower end inlet seal of evaporimeter are fixed, evaporimeter is communicated with a channel seal of weary wind source heat pump by medium transport pipe and medium back flow pipe, and another passage of weary wind source heat pump to be sealed with user by inlet tube and outlet tube water pump and communicates.
The present invention has following advantages: 1), by weary wind and medium directly exchange, and fully can reclaim the heat energy in air draft; Reclaim the sensible heat in air draft and latent heat simultaneously; 2), design side at retention tower, the heat exchange area of evaporimeter can carry out four sides and arrange, evaporimeter size easily regulates, and makes weary distinguished and admirable speed even, invests little; 3), be arranged on the side of retention tower, effectively can overcome the resistance that system increases, newly-increased resistance is less than 100pa, little on Mine Ventilator impact.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, Mine Ventilator 1 to be sealed with the lower end of weary wind retention tower 3 by mine air channel 2 and communicates, the upper end outlet of weary wind retention tower 3 and the lower end inlet seal of evaporimeter 4 are fixed, evaporimeter 4 is communicated with a channel seal of weary wind source heat pump 14 by medium transport pipe 16 and medium back flow pipe 15, another passage of weary wind source heat pump 14 by inlet tube and outlet tube 12,13, water pump 11 to seal with user 10 and communicates.
Fixed stop wind apparatus 6 on the upper end outlet of described evaporimeter 4.When evaporimeter 4 blocks, automatically open, ensure that mine air-lack circulation is smooth and easy.
The upper end of described evaporimeter 4 is fixed with nozzle 5, and nozzle 5 to be sealed with high-pressure spraying water pump 9 by spray header 7, valve 8 and communicates.Evaporimeter 4 is cleaned.
Mine air channel 2 internal fixtion near described Mine Ventilator 1 has hygrometric device 17 and temperature measuring equipment 18.
Mine air-lack to mine air channel 2, after measuring weary rheumatism degree 17, temperature 18, changes direction by Mine Ventilator 1, distinguished and admirablely enters evaporimeter 4 upward to weary wind retention tower 3, after weary wind and medium carry out interchange of heat, enters in air.Medium flow back into weary wind source heat pump 14, and carry out medium and water thermal power transfer, medium, is recycled getting back to evaporimeter 4 by medium transport pipe.Water enters heat user 10 and recycles.
