Description
Technical field
The utility model relates to a kind of spraying and dedusting heat reclamation device, belongs to the fire coal boiler fume heat recovery technology.
Background technology
Existing boiler afterheat reclaims, and majority is that several heat exchanging water pipes are set in flue, and flue-gas temperature is reduced by heat exchange, and heat exchanging water pipe's water temperature rises, and heat obtains reclaiming, and the heat exchanging water pipe that the while flue dust is arranged stops that the grit of discharging descends.This waste heat recovery and dust removing effects are not best, and waste heat recovery and dedusting technology are the problems of research always.
Summary of the invention
The purpose of this utility model provides a kind of spraying and dedusting heat reclamation device, and this device can reduce the boiler emission thing and satisfy environmental protection requirement, energy recovery waste heat, the operating efficiency of raising coal-burning boiler.
The technical solution of the utility model is: a kind of spraying and dedusting heat reclamation device, comprise main frame, it is characterized in that: in main frame, shower is equipped with at the top, evaporimeter is equipped with in the bottom, it between shower and the evaporimeter spray chamber, the main frame bottom is provided with water leg, the main frame machine wall of spray chamber both sides is provided with smoke inlet and exhanst gas outlet, the shower input port is connected with circulating pump pipeline, on the connecting pipe between circulating pump and the water leg delivery outlet excretion machine is housed, the input port of evaporimeter is connected with the leakage fluid dram pipeline of expansion throttling valve, and the delivery outlet of evaporimeter is connected compressor with the air entry pipeline of compressor, condenser, the expansion throttling valve, pipeline connects successively, and the heat exchanger tube that is connected with the steam generator system water return pipeline is housed in the condenser.
The smoke inlet of present technique is communicated with the discharge flue of coal-burning boiler, and exhanst gas outlet is located at outside the main frame.Liquid refrigerant is housed in the evaporimeter.
The operation principle of this device is: with the high-temperature flue gas mixture (temperature is more than 130 ℃) that is produced in the coal-burning boiler combustion process, cause in the spray chamber, carry out heat exchange with shower water (temperature is about 3 ℃), be flue-gas temperature decline (temperature is about 10 ℃), shower water temperature rising (temperature is about 8 ℃), the shower water that temperature rises sprays on the evaporimeter of spray chamber bottom, carry out heat exchange with the cold-producing medium (temperature is about 0 ℃) in the evaporimeter, back shower water temperature decline (temperature is about 3 ℃), enter in the water leg, by circulating pump it is delivered to the spray chamber top again and spray, finish absorption and this process of release heat.Cold-producing medium after the heat exchange then temperature rises (temperature is about 5 ℃), forms thermal evaporation, and the gaseous refrigerant after the evaporation forms high temperature and high pressure gas by the compressor compresses cold-producing medium, enters the unit condenser, carries out heat exchange with the steam generator system backwater.System water then temperature rises, after enter boiler.Cold-producing medium then temperature descends, and gaseous refrigerant is crossed cold back condensation becomes liquid state, and the high-temperature liquid state cold-producing medium is by expansion valve throttling, step-down, make refrigerant temperature descend rapidly (temperature is 0 ℃) enter and continue heat exchange in the evaporimeter.This device is finished evaporation, compression, condensation, expansion one-period, repeats this cycle again, thus the flue gas waste heat recovery of circulation realization coal-burning boiler repeatedly.The various emissions that coal-burning boiler burning produces are diluted by water through spray, and again through separating, it is minimum that dust, sulfur dioxide, the greenhouse gases amount of boiler emission are reduced to, and the service efficiency of coal-burning boiler and coal-fired utilization rate are improved.
