Description
Technical field
The invention belongs to field of Environment Protection, more particularly to a kind of tunnel kiln smoke-gas environment-protective circulating processing system.
Background technology
The waste gas that adobe burning is produced in traditional type tunnel cave profit is done by carrying out adobe in smoke exhaust fan feeding dry kiln
Dry, the pernicious gas produced after drying enters desulfurization dust-removal system and carries out air and staticize treatment through moisture-eliminating blower.Exist shortcoming and
It is not enough：
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, influence 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 discharge mode in dry kiln because being mixed into substantial amounts of fresh sky
Gas, oxygen content expands more than ten times through oxygen content conversion typically between 18%-19% 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.
The content of the invention
For above-mentioned the deficiencies in the prior art, the present invention provides a kind of tunnel kiln smoke-gas environment-protective circulating processing system.The tunnel
The energy-conserving and environment-protective of road kiln fume environment protection circulating treating system, reduce operating cost.
The technical scheme is that：A kind of tunnel kiln smoke-gas environment-protective circulating processing system, including tunnel calcining kiln taking, it is described
Tunnel calcining kiln taking sets gradually preheating section, furnace zone, soaking zone, cooling section, and the preheating section connects smoke exhaust fan, smoke exhaust fan
Desulphurization denitration dust pelletizing system is connected by smoke discharging pipe, the preheating section Inner Front End is provided with afterheat utilizing system, preheating section stage casing
Balance blower fan is provided with, rear end is provided with exhausting moisture pipeline, and air-heater is sent in balance wind pipe road one end connection balance blower fan, other end connection,
Drying duct, send hot channel to be each provided in tunnel chamber for drying, tunnel chamber for drying connects dehydration device by dehydrated tube, take off
Water installations connect humidity discharging breeze fan by pipeline, and humidity discharging breeze fan connects the cooling of tunnel calcining kiln taking by exhausting moisture pipeline
Section.
Of the invention have the effect to be：The harmful exhaust that tunnel calcining kiln taking burning of the present invention is produced directly is sent with smoke exhaust fan
To enter processed in the out of stock dust pelletizing system of desulfurization, therefore process does not have fresh oxygen to be mixed into, oxygen content is typically left in 10%-13%
The right side, conversion multiple is low, environment protection standard.Sent by heat supply blower fan with cooling section high temperature cleaning waste heat using tunnel calcining kiln taking soaking zone
Entering tunnel chamber for drying's dry kiln carries out brick bat drying, and dried moist waste gas sends into dewatering system by moisture-eliminating blower, takes off
Roast kiln tail portion is sent into after water, realizes recycling with air flow.Tunnel chamber for drying is using kiln tail cleaning dry heat source, moisture content
Content is small, and moisture is small in dry kiln, service life of fan extension.Humidity discharging waste gas is circulated after being removed water into roast kiln tail
Burning is utilized, and reduces air pollution, meets national policy.Save electric energy and environmentally friendly operating cost.
