Abstract
The utility model discloses a gas power generation waste heat recycling device. According to the utility model, a heat collecting device is arranged at a flue gas outlet of a gas electric generator. The heat collecting device is mainly composed of a circulating water sealing chamber (1), a flue gas sealing chamber (2) and heat exchange tubes (3). The circulating water sealing chamber and the flue gas sealing chamber are two independent chambers. The flue gas sealing chamber is positioned below the circulating water sealing chamber. The heat exchange tube penetrates through the circulating water sealing chamber and the flue gas sealing chamber. The upper portion of each heat exchange tube is positioned inside the circulating water sealing chamber (1), and the lower portion of each heat exchange tube is positioned inside the flue gas sealing chamber (2). Each heat exchange tube (3) is filled with a heat exchange medium. As the heat collecting device is arranged at the flue gas outlet of the gas electric generator, recycling of waste heat is realized. Thus, environmental pollution is avoided, energy is saved, and waste is avoided. Processed heat can be used in heating bath water, thus achieving the purpose of saving energy and protecting the environment.
Description
Technical field
The utility model relates to a kind of gas generating residual heat recovery and utilization technology field.A kind of gas generating residual heat recycle device specifically.Be applicable to colliery and reclaim the utilization of fume afterheat after gas electricity.
Background technology
At present, at some large-scale gas electricity stations, because gas electricity unit quantity is many, and install more concentrated, waste heat amount is large (exhaust gas temperature is up to 550 ℃) very, therefore, mostly adopt after the high-temperature tail gas collection of all gas electricity units, by waste heat boiler, produce steam and generate electricity.But at some small-sized gas electricity stations, because its gas electricity unit quantity is few, if adopt cogeneration, relative investment is very large, reclaims benefit much smaller than gross investment, therefore at small-sized gas electricity station, substantially can not do cogeneration project.The fume afterheat of many collieries industry after to gas electricity is not all used substantially, but directly the flue gas that contains amount of heat is directly discharged in air, and this has not only caused the waste of the energy, causes yet a kind of thermal source of environment is polluted simultaneously.
Summary of the invention
The purpose of this utility model produces thus, proposes the device that a kind of gas generating residual heat is recycled.By reclaiming gas electricity machine smoke discharging residual heat, reaching, save the energy, protection of the environment, avoid waste, reduce the object of energy consumption.
The purpose of this utility model is realized by following technical method: at gas electricity machine flue gas exhaust opening, place arranges heat collection device, described heat collection device is mainly by recirculated water closed chamber, flue gas closed chamber and heat exchanger tube form, described recirculated water closed chamber and flue gas closed chamber are two independently chambers, flue gas closed chamber be positioned at recirculated water closed chamber below, described heat exchanger tube is applied in recirculated water closed chamber and flue gas closed chamber, the top of each heat exchanger tube is all positioned at recirculated water closed chamber, bottom is all positioned at flue gas closed chamber, at heat exchanger tube, all add and have heat exchange medium.
The water inlet of recirculated water closed chamber described in the utility model is connected with water tank with running water pipe respectively with delivery port.
On the heat exchanger tube that is positioned at flue gas closed chamber described in the utility model, there is fin.
One end of flue gas closed chamber described in the utility model is provided with flue gas air inlet, the other end is provided with flue gas air outlet.
The heat exchange medium adding in heat exchanger tube described in the utility model is demineralized water.
The utility model is by arranging heat collection device at gas electricity machine flue gas exhaust opening place; realized the recycling of waste heat; not only avoided the pollution to environment; and saved the energy, avoided waste; heat after processing can be used for heating publilc baths bath water, reaches the object of saving the energy, protection of the environment.

The specific embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1 with Figure 2: the device that the gas generating residual heat described in the present embodiment is recycled is mainly comprised of recirculated water closed chamber 1, flue gas closed chamber 2 and heat exchanger tube 3, recirculated water closed chamber and flue gas closed chamber are two independently chambers, adopt Q235 carbon steel seamless welding to form.Flue gas closed chamber 2 be positioned at recirculated water closed chamber below, one end is provided with flue gas air inlet 5, the other end is provided with flue gas air outlet 6.The recirculated water water inlet 4 of recirculated water closed chamber 1 is connected with water tank with running water pipe respectively with recirculated water delivery port 7.Heat exchanger tube 3 is a plurality of, all in recirculated water closed chamber and flue gas closed chamber.The top of each heat exchanger tube is all positioned at recirculated water closed chamber, bottom and is all positioned at flue gas closed chamber, at heat exchanger tube, all adds and has heat exchange medium.Heat exchanger tube 3 adopts Q235 to be welded into sealed tube, for delaying the time of equipment scaling, vacuumizes and have a demineralized water of approximately 1/2nd in heat exchanger tube.For increasing the heat exchange area of flue gas closed chamber 2 interior heat exchanger tubes 3, the heat exchanger tube 3 that is positioned at flue gas closed chamber 2 is provided with fin.
Use makes, at gas electricity machine flue gas exhaust opening, gas generating residual heat recycle device of the present invention is installed at place, the high-temperature flue gas that gas electricity machine is discharged enters in flue gas closed chamber 2 by flue gas closed chamber air inlet 5, and the demineralized water of heat exchanger tube 3 inside absorbs after the heat in high-temperature flue gas evaporation and becomes high-temperature gas and be placed in the first half in heat exchanger tube 3.Carry out heat exchange with the running water entering in circulation water seal cavity, after the heat of running water absorption heat-exchange pipe 3 interior high-temperature steams, flow in water tank, the interior high-temperature steam of heat exchanger tube 3 is emitted condensation after heat, flows to the bottom of heat exchanger tube 3 along heat exchanger tube 3 inwalls, again by high-temperature flue gas, is heated.Circulate and so forth, reach the object of heat in recovered flue gas.Heated running water flows into water tank and is stored, and delivers to user, as uses such as bathings, reaches the object of heat recovery and utilization.
