Abstract
The utility model relates to the technical field of coal mine mineshaft anti-freezing and return air heat energy utilization, in particular to a mineshaft anti-freezing device by return air heat energy. The mineshaft anti-freezing device is characterized by comprising a coiled tube type return air heat exchanger, a circulating pump and an air inlet heater, the return air heat exchanger is arranged at a position of a mine ventilation diffusion tower outlet, a water outlet of the return air heat exchanger is connected with a water inlet of the circulating pump, a water outlet of the circulating pump is connected with a water inlet of the air inlet heater, the air inlet heater is mounted in a well head house on an air inlet mineshaft, and a water outlet of the air inlet heater is connected with the water inlet of the return air heat exchanger through a pipeline. According to the mineshaft anti-freezing device by the return air heat energy, when the mineshaft anti-freezing device is in operation, circulating water in closed circulation takes away return air heat energy through the return air heat exchanger under the action of the circulating pump to enter the air inlet heater to heat inlet air in the mineshaft, so that mineshaft anti-freezing can be achieved by direct usage of the return air heat energy. The mineshaft anti-freezing device by the return air heat energy has the advantages that the number of components is small, a system is simple, the operation is stable and reliable, and the use ratio of the return air heat energy is increased.
Description
(1) technical field
The utility model relates to that mine shaft is antifreeze, return air heat energy utilizes technical field, and particularly a kind of return air heat energy is realized the device of equipment.
(2) background technology
For promoting the colliery UTILIZATION OF VESIDUAL HEAT IN, coal association determines that " research and development colliery heat energy utilization and equipment, strive for producing coal and do not burn coal " is an important task in coal energy-saving in " about advancing coal industry to develop a circular economy, promoting the instruction of energy-saving and emission-reduction work ".For guaranteeing safety and maintaining production, mine must be ventilated.Mine ventilation is a ring the most basic in the mine production link, and it occupies very important status all the time at mine construction and production period.
Winter, when the mining area outside air temperature during lower than 0 ℃, if inlet air equipment problem solves badly, the pit shaft trickle can be under the Cryogenic air effect, and the cage guide in the borehole wall, pit shaft, buntons, hoisting container, cable, water pipe etc. are located to freeze, the pit shaft hoisting power is descended, the ventilation section reduces, and also can cause that card tank, holder tank lock open and close inconvenience, anti-fall insurance malfunctioning etc., water ice slump when serious, cause the major accident of damaging pit gear and casualties, affect mine safety production.Therefore, pitshaft is antifreeze very important to guaranteeing colliery normal production in winter, and the equipment heat requirement accounts for larger proportion in the heating demand of colliery.
Colliery is a huge heat storage, contains abundant geothermal energy resources.The air that enters colliery constantly carries out interchange of heat with colliery, and finally, the ground temperature in air and colliery reaches balance.The ground temperature substantially constant in colliery, cause the annual temperature substantially constant of coal mine return air, is subject to the impact of outside air temperature seldom.So, coal mine return air be first stability than the residual heat resources of high-quality.
The coal mine return air amount equals intake, and return air temperature is far above EAT, and therefore, it is feasible utilizing return air heating air intake to meet part or all of equipment load.The mode that existing return air utilizes technology all to adopt spray is by the thermal power transfer of return air in water, and the recycling water resource heat pump extracts the mode of the heat energy in water, belongs to the indirect utilization return air heat energy, and this mode link is more, and efficiency is not high.
(3) summary of the invention
In order to improve the utilization ratio of return air heat energy, reduce the heat exchange link, improve the safety reliability, the utility model provides a kind of device that directly utilizes return air heat energy to realize equipment.
The utility model is realized by the following technical solutions:
A kind of device that utilizes return air heat energy to realize equipment, it is characterized in that: comprise coiled return-air heat exchanger, circulation pump and air intake heater, described return-air heat exchanger is located at mine ventilation retention tower exit, its delivery port connects the water inlet of circulation pump, the delivery port of circulation pump connects air intake heater water inlet, described air intake heater is located in the heapstead on Intake shaft, and the delivery port of air intake heater is connected to the water inlet of return-air heat exchanger by pipeline.
The beneficial effects of the utility model: during device operation of the present utility model, recirculated water in closed cycle is under the effect of circulation pump, take away the heat energy of return air by return-air heat exchanger, enter again heating pit shaft air intake in the air intake heater, realize directly utilizing return air heat energy to realize the purpose of equipment.This device assembly is less, and system is simple, and stable and reliable operation has improved the utilization rate of return air heat energy.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
In figure, 1 return-air heat exchanger, 2 circulation pumps, 3 air intake heaters, 4 heapsteads, 5 pit shafts, 6 mine return airs, 7 pit shaft air intakes.
(5) specific embodiment
A kind of device that utilizes return air heat energy to realize equipment as shown in the figure, comprise coiled return-air heat exchanger 1, circulation pump 2 and air intake heater 3, described return-air heat exchanger 1 is located at mine ventilation retention tower exit, its delivery port connects the water inlet of circulation pump 2, the delivery port of circulation pump 2 connects air intake heater 3 water inlets, described air intake heater 3 is located in the heapstead 4 on Intake shaft 5, and the delivery port of air intake heater 3 is connected to the water inlet of return-air heat exchanger 1 by pipeline.
Recirculated water in mine return air and closed cycle carries out interchange of heat in return-air heat exchanger 1, recirculated water is taken away the heat of return air, under the effect of circulation pump 2, recirculated water enters air intake heater 3 and carries out interchange of heat with pit shaft 5 air intakes, heating pit shaft air intake, realize directly utilizing return air heat energy to realize the purpose of equipment.For preventing that heat exchanger from freezing, add anti-icing fluid in recirculated water.
