Description
Technical field
The utility model relates to one and utilizes steam boiler tail gas thermal source, reduces the steam boiler tail-gas recycling device of steam boiler tail gas dust simultaneously.
Background technology
Steam boiler is the one of Industrial Boiler, in all trades and professions application all widely.The exhaust temperature that conventional vapor boiler directly discharges reaches 300 ~ 500 DEG C, does not meet national standard control overflow, and containing a large amount of dust in steam boiler tail gas, environmental pollution is serious.How utilizing steam boiler tail gas thermal source fully, realize the zero-emission of steam boiler tail gas dust simultaneously, is a research direction highly significant.
Summary of the invention
The utility model object is to provide one to utilize steam boiler tail gas thermal source, reduces the steam boiler tail-gas recycling device of steam boiler tail gas dust simultaneously.
The technical solution of the utility model is:
Steam boiler tail-gas recycling device, comprise heat exchanger, alkali lye deduster, silk alkali cleaning pond, wherein heat exchanger is arranged in drying room, heat exchanger air inlet is connected with the exhaust port of steam boiler, and heat exchanger gas outlet is connected with alkali lye deduster, and alkali lye deduster gas outlet is connected with chimney by air-introduced machine; Described alkali lye deduster also comprises alkali lye deduster inlet, and wherein alkali lye deduster inlet is connected by the outlet of water pump with silk alkali cleaning pond, and alkali lye deduster bottom has outlet to lead to sewage disposal system.
Described steam boiler is the boiler that bavin, coal or agricultural crop straw can be used to be fuel.
Described alkali lye deduster, the spent lye of being discharged by silk alkali cleaning pond cleaning dedusting, reduces smoke stack emission flue dust and dusty gas.
In order to improve the thermal efficiency in drying room, one or more groups heat exchanger can be set.
The utility model device takes full advantage of the spent lye in the heat energy of steam boiler tail gas and silk alkali cleaning pond, simultaneously after the process of the utility model device, achieves the zero-emission of steam boiler tail gas dust, has good practical value and the value of environmental protection.
The beneficial effects of the utility model:
The utility model can be applied to food factory's food drying, chemical plant material dewatering, silk cocoon reeling mill give up, and silk dries etc. needs dry enterprise, a large amount of energy can be saved, the sulfur dioxide of exhanst gas outlet is neutralized by alkali lye, decreases the pollution of sour gas to air.
