Abstract
The utility model discloses a mine return air after-heat recovery heat exchanger, which belongs to the field of mine after-heat recycling. The heat exchanger comprises an air duct and a mine ventilator; a passage A and a passage B are arranged at an air exhaust opening of a mine air return well, and the passage A and the passage B are connected with the mine ventilator in a mine through the air duct; a muffler device is arranged in the passage A; a heat exchange tube is arranged in the passage B; a washing tube is arranged above the heat exchange tube; an exhaust fan is arranged above the washing tube; and an air deflector is arranged below the heat exchange tube. Compared with the prior art, the mine return air after-heat recovery heat exchanger provided by the utility model has the characteristics of reasonable design, simple structure, low operation cost and the like, and is convenient to install and maintain. In addition, the circulating water circulates in a closed loop, so the water quality is not affected by return air; and moreover, the dust content and water content in the return air are reduced greatly, and the influences of the return air to the surrounding environment are reduced effectively.
Description
Technical field
The utility model relates to mine heat recovery field, specifically mine return air heat recovery heat exchanger.
Background technology
China's economy increases fast, and each item construction obtains great achievement, but has also paid huge resource and the ruined cost of environment, and the contradiction between the two is sharp-pointed day by day.Only adhere to practicing thrift development, cleaning development, security developments, could realize sound and rapid economic growth.Simultaneously, greenhouse gas emission causes global warming, enjoys international community's extensive concern.Further strengthening energy-saving and emission-reduction work, also is pressing for of reply Global climate change.
Coal enterprise is as production of energy enterprise; Also be the big power consumer simultaneously; Have a responsibility for obligatedly changing our way of thinking about development conscientiously, create a new pattern of growth, improve the development quality; Implement the target for energy-saving and emission-reduction that the Eleventh Five-Year Plan outline is confirmed, promote coal industry saving, cleaning, safety and sustainable development.
Coal enterprise needs conscientiously in light of its own characteristics, and energy-saving excavation reduces discharging potentiality.For guarantee safety with keep production, mine ventilation is a ring the most basic in the mine production link, it occupies important status all the time at mine construction and production period.
The air that gets into mine constantly carries out interchange of heat in mine, final, the ground temperature of air and mine reaches balance.Because the ground temperature substantially constant of mine, so the annual temperature substantially constant of mine return air, the influence that receives outside air temperature seldom.Therefore, contain a large amount of Lowlevel thermal energy resources in the mine return air.If these residual heat resources are used, will advance the energy-saving and emission-reduction work in colliery, have good economic and social benefit.
Existing return air heat exchanger all adopts open circulation, return air and recirculated water direct heat transfer mode, and system complex, operating cost is high.
Summary of the invention
The technical assignment of the utility model is to above weak point, and a kind of simple in structure, installation and maintenance convenient, operating cost is low mine return air heat recovery heat exchanger is provided.
The utility model solves the technical scheme that its technical problem adopted: this mine return air heat recovery heat exchanger comprises air channel and mine ventilation machine; Mine returnairshaft air outlet place is equipped with A channel and B passage, and A channel is connected with the interior mine ventilation machine of mine through the air channel with the B passage; Silencing apparatus is installed in the A channel, in the B passage heat exchanger tube is installed, the top of heat exchanger tube is equipped with cleaning hose, and the top of cleaning hose is equipped with exhaust blower, and the below of heat exchanger tube is equipped with cowling panel.
The junction in described A channel and air channel is provided with leafy valve.
The bottom in described air channel is provided with catch basin.
Heat transferring medium in the described heat exchanger tube does not directly contact with mine return air.
The mine return air heat recovery heat exchanger of the utility model is compared with prior art, has characteristics such as reasonable in design, simple in structure, that installation and maintenance convenient, operating cost is low, and in addition, recirculated water adopts closed cycle, and water quality does not receive the influence of return air; And the dustiness in the return air and water content reduce greatly, effectively reduces the influence of return air to surrounding environment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of mine return air heat recovery heat exchanger.
Among the figure: 1, leafy valve, 2, cowling panel, 3, the air channel, 4, heat exchanger tube, 5, cleaning hose, 6, exhaust blower, 7, A channel, 8, the B passage, 9, the mine ventilation machine, 10, catch basin, 11, silencing apparatus.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The mine return air heat recovery heat exchanger of the utility model; Its structure comprises air channel 3 and mine ventilation machine 9; Mine returnairshaft air outlet place is equipped with A channel 7 and B passage 8, and A channel 7 is connected with the interior mine ventilation machine 9 of mine through air channel 3 with B passage 8, and the bottom in air channel 3 is provided with catch basin 10; Silencing apparatus 11 is installed in the A channel 7; A channel 7 is provided with leafy valve 1 with the junction in air channel 3; Heat exchanger tube 4 is installed in the B passage 8, and the heat transferring medium in the heat exchanger tube 4 does not directly contact with mine return air, and the top of heat exchanger tube 4 is equipped with cleaning hose 5; The top of cleaning hose 5 is equipped with exhaust blower 6, and the below of heat exchanger tube 4 is equipped with cowling panel 2.
During the return air heat energy utilization, the leafy valve 1 of the import of A channel 7 cuts out, return air passes through B passage 8 under the effect of mine ventilation machine 9 overbottom pressure or exhaust blower 6.In B passage 8, return air constantly is delivered to heat in the recirculated water in heat exchanger tube 4 finned coils, and heat cycles water utilizes other devices (like water resource heat pump etc.) through extracting the heat in the recirculated water, to reach the purpose of indirect utilization return air heat energy again.After heat exchange was accomplished, the return air of low temperature drained into atmosphere.
