Description
Technical field
The utility model belongs to field of Environment Protection, more particularly to a kind of tunnel kiln smoke-gas environment-protective circulating processing system.
Background technology
Waste gas caused by adobe burning is sent into progress adobe in dry kiln by smoke exhaust fan and done in traditional type tunnel cave profit
Dry, caused pernicious gas is discharged into desulfurization dust-removal system progress air and staticizes processing through moisture-eliminating blower after drying.Exist shortcoming and
Deficiency：Because in adobe combustion process, moisture content remaining in adobe can together be changed into vapor and brought into dry kiln, through drying
Kiln humidity discharging brings pressure, somewhat careless manipulation, can cause base phenomenon of collapsing, and influences production and product quality.
It is newest《People's Republic of China's heavy clay industry atmosphere pollutants emission standardses》In to discharge Emissions requirements peroxide system
Number is 1.7, i.e., basic oxygen content about 8.67, and traditional waste gas discharging modes in dry kiln because being mixed into substantial amounts of fresh sky
Gas, oxygen content expand more than ten times typically between 18%-19%, through oxygen content conversion on the basis of measured value, and environment protection standard is stranded
It is difficult.
Heat supply humidity discharging air quantity power consumption bigger than normal is high, and environmental protection facility operating cost is high.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of tunnel kiln smoke-gas environment-protective circulating processing system.
The tunnel kiln smoke-gas environment-protective circulating processing system energy-conserving and environment-protective, reduce operating cost.
The technical solution of the utility model is：A kind of tunnel kiln smoke-gas environment-protective circulating processing system, including tunnel calcining kiln taking,
The tunnel calcining kiln taking sets gradually preheating section, furnace zone, soaking zone, cooling section, and the preheating section connects smoke exhaust fan, smoke evacuation
Blower fan connects desulphurization denitration dust pelletizing system by smoke discharging pipe, and the cooling section Inner Front End is provided with afterheat utilizing system, cooling section
Stage casing is provided with balance blower fan, and rear end is provided with exhausting moisture pipeline, balance wind pipe road one end connection balance blower fan, and hot blast is sent in other end connection
Machine, drying duct, hot channel is sent to be each provided in tunnel chamber for drying, tunnel chamber for drying connects dehydration dress by dehydrated tube
Put, dehydration device connects humidity discharging breeze fan by pipeline, and humidity discharging breeze fan connects tunnel calcining kiln taking by exhausting moisture pipeline
Cooling section.
It is of the present utility model to there is an effect to be：Harmful exhaust caused by the burning of the utility model tunnel calcining kiln taking is directly with row
Cigarette blower fan is sent into the out of stock dust pelletizing system of desulfurization and handled, therefore process does not have fresh oxygen to be mixed into, and oxygen content typically exists
10%-13% or so, conversion multiple is low, environment protection standard.Passed through using tunnel calcining kiln taking soaking zone and cooling section high temperature cleaning waste heat
Heat supply blower fan is sent into tunnel chamber for drying's dry kiln and carries out brick bat drying, and dried moist waste gas is sent into de- by moisture-eliminating blower
Water system, roast kiln tail portion is sent into after dehydration, realizes and recycle with air flow.Tunnel chamber for drying is clean dry using kiln tail
Thermal source, water content is small, and moisture is small in dry kiln, and service life of fan extends.Humidity discharging waste gas enters roast kiln after being removed water
Tail carries out circulating combustion utilization, reduces air pollution, meets national policy.Save electric energy and environmentally friendly operating cost.
