Abstract
The utility model relates to a coal slime drying recovery of waste heat utilization system, which has the advantages of simple structure and easy use, fully utilizes the waste heat of a wet dust catcher and reduces waste of energy sources. The coal slime drying recovery of waste heat utilization system is characterized in that the excess flow device of the wet dust catcher is connected with at least one heat exchanger, and one outlet of the heat exchanger is connected with a pollution discharge pond. Meanwhile, another outlet of the heat exchanger is connected with an air conditioning plant by a pipeline, and the air conditioning plant is connected with a water storing pond. The water storing pond is connected with another inlet of the heat exchanger by a circulating device, and the water storing pond is provided with an external heat-supplying pipeline.
Description
Technical field
The utility model relates to a kind of pre-heat recovery system, relates in particular to the dry heat recovery of a kind of coal slime system.
Background technology
In muddy material drying systems such as coal slime, brown coal, dry run is strong matter heat exchanging process, high temperature thermal medium is with the water evaporates in the muddy material, contain a large amount of heats in the tail gas, the exhaust gas processing device wet scrubber has absorbed a large amount of heats in the spray cleaning flue gas, the wastewater temperature of discharging is about 50-80 ℃, with sewage pump it is squeezed into cesspool or flows in the cesspool naturally in the sewerage in the past, heat has wasted and has not obtained utilizing, and has caused a large amount of energy wastes.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, easy to use, can make full use of the waste heat of wet scrubber, reduces the dry heat recovery of the coal slime system of energy waste.
For achieving the above object, the utility model adopts following technical scheme:
The dry heat recovery of a kind of coal slime system, it comprises that the overflow mechanism of wet scrubber is connected with at least one heat exchanger, heat exchanger exit is connected with pollution discharge pond; Another outlet of heat exchanger simultaneously is connected with aircondition by pipeline, and aircondition then is connected with tank simultaneously, and tank is connected with another import of described heat exchanger by EGR, and tank is provided with external heat supplying pipeline.
Described heat exchanger is a water-to-water heat exchanger.
Described aircondition is the fan coil device.
Described EGR is a water circulating pump.
The utility model installs a heat exchanger additional at the wet scrubber sewage pipe Overflow drainage mouth of pipe of drying system, utilize the thermal conductivity of water to utilize heat exchanger with the clear water circulatory system of the exchange heat in the effluent cycle system to the heat exchanger opposite side, sewage flows into the gutter naturally from the heat exchanger discharge outlet, clear water is just squeezed into plate type heat exchanger clear water end by water source heat pump units, exchange heat in the effluent cycle system is come out, the clear water of circulation is connected with fan coil through piping, fan coil is the end equipment of residual neat recovering system, fan coil relies on the positive action of blower fan, be heated when making air by heater surfaces, heat in the clear water circulatory system is exchanged once more, current constantly circulate, the hot blast that forms is sent into indoor, reaches the purpose of heating.Utilize fan coil heat to be dispersed into each room that needs heating by the pipeline delivering hot water like this, independently fan coil and gauge tap are installed in each room, the convenient temperature of regulating, water in the circulating water pipe is finally got back in the clear water cycle set water tank, water in the header tank also can be used for bathing or domestic water, dry residual neat recovering system efficient is very high, can reach 35 ℃ by this residual neat recovering system indoor temperature, reaches comfort temperature by by-pass cock.
The beneficial effects of the utility model are: simple in structure, easy to use, and can be with the waste heat recovery in the muddy material drying system, so that resource is fully utilized.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. wet scrubber, 2. spill box, 3. heat exchanger, 4. fan coil, 5. tank, 6. water circulating pump.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, it comprises wet scrubber 1, and the spill box 2 of wet scrubber 1 is connected with heat exchanger 3, and heat exchanger 3 can be one or more.Sewage after the heat exchange flows into cesspool from the discharge outlet of heat exchanger 3.Clear water pipeline in the heat exchanger 3 is heated simultaneously, and clear water flows in the fan coil 4 then, and the wind that blower fan blows out uses for the user as the air-conditioning thermal source through coil pipe heating back.Hot water in the coil pipe then flows out to tank 5, and tank 5 is connected with water circulating pump 6, and water circulating pump 6 is constantly sent into the water in the tank 5 in the heat exchanger 3, guarantees the proper flow of water.Hot water in the tank 5 can use for bathing simultaneously.
