Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of asphalt smoke purifying device, as shown in Figure 1, comprise bitumen flue gas pipeline, described asphalt smoke purifying device also comprises: circulating water pool 1, shower 2, spray column 3, packing layer 4, drying roller 5 and high comb 6.Described bitumen flue gas pipeline is communicated with the sidepiece of described spray column 3, preferably, to be provided with volume damper 8 at bitumen flue gas pipeline with being communicated with of described spray column 3.
The bottom of described spray column 3 is communicated with described circulating water pool 1, described circulating water pool 1 is built with akaline liquid, described spray column 3 inside sets gradually shower 2, packing layer 4 from down to up, shower 2 in described spray column 3 is provided with shower nozzle, one end of described shower 2 is provided with absorption water pump 7 and is placed in described circulating water pool 1, the top of described spray column 3 is communicated with described drying roller 5, and described drying roller 5 is communicated with described high comb 6.
Preferably, the inner matter of described packing layer 4 comprises adsorbent and strippant, and described adsorbent is calcined coke or active carbon, and described strippant is inert gas.
Preferably, when described adsorbent is calcined coke, the temperature of described packing layer 4 is 60 DEG C-90 DEG C, and in this temperature range, calcined coke has good suction-operated to bitumen flue gas.
Further preferably, when described adsorbent is calcined coke, the temperature of described packing layer 4 is 70 DEG C-80 DEG C, in this temperature range, technique easily realizes, and meanwhile, calcined coke, to the advantages of good adsorption effect of bitumen flue gas, is conducive to commercial Application.
As most preferred embodiment, when described adsorbent is calcined coke, the temperature of described packing layer 4 is 70 DEG C, and calcined coke is best to the adsorption effect of bitumen flue gas.
Preferably, described drying roller 5 is high-temperature burner.
In the present embodiment, bitumen flue gas enters spray column 3 through volume damper 8, adsorbs water pump simultaneously and from circulating water pool 1, adsorbs akaline liquid in shower 2, is purified bitumen flue gas by shower nozzle first time.Now, the materials such as the particle in bitumen flue gas, CO, under akaline liquid effect, to be flowed back to by the bottom of spray column 3 in the circulating water pool 1 be communicated with it with akaline liquid, form recycling of akaline liquid.
Through first time, the bitumen flue gas of evolution process enters packing layer 4, adopts calcined coke or active carbon as adsorbent, adopts inert gas as strippant, carries out second time purification by adsorption-desorption to pitch smog.Within the scope of normal temperature, the Adsorption Effect of calcined coke to bitumen flue gas is not obvious, within the scope of 60 DEG C-90 DEG C, calcined coke has good absorption to bitumen flue gas, within the scope of 70 DEG C-80 DEG C, technique easily realizes, meanwhile, calcined coke, to the advantages of good adsorption effect of bitumen flue gas, is conducive to commercial Application.70 DEG C time, calcined coke is best to the adsorption effect of bitumen flue gas, and the adsorption efficiency of calcined coke is Aned Zhao≤94% and considered.Example, when adopting calcined coke as adsorbent, the shower 2 in spray column 3 and any position between packing layer 4, arrange heating temperature measuring equipment, thus reach the optimal adsorption temperature of calcined coke.
Absorption is a kind of adsorption, hydrocarbon selectively can be adsorbed onto adsorbent surface.Under normal conditions, adsorption capacity increases with being increased by adsorb organic compound molecular weight, and unsaturated compound is more complete than saturated compounds absorption, cyclic organic compounds more easily adsorbs.
Adsorption process comprises sorption and desorption two processes, adsorption process is that in multiple unit adsorbent, rotation is carried out continuously, and desorb intermittently carries out, bitumen flue gas is attracted on the surface of calcined coke by the carbon bed of active carbon or bitumen flue gas, when absorption is close to time saturated, carbon bed or calcined coke outlet bitumen flue gas concentration raise and show that absorption reaches critical point, and now strippant starts automatically to carry out desorption and regeneration process, here, strippant is inert gas.
Bitumen flue gas after second time purification, then enter drying roller 5 and carry out high temperature burning handling, carrying out third time purifies, and reaches multistage processing procedure, finally qualified calibrating gas is entered air.
This asphalt smoke purifying device that the utility model provides, akaline liquid in employing absorption water pump 7 sorption cycle pond 1 is in shower 2, by shower nozzle, first time purification is carried out to bitumen flue gas, then by the adsorption-desorption of packing layer 4, second time purification is carried out to bitumen flue gas, then carry out high temperature burning handling by drying roller 5 pairs of bitumen flue gas and carry out third time purification, finally the pure qi (oxygen) reaching national environmental standard is entered air through too high comb 6.Solve prior art medium pitch fume treatment shortcoming improperly, purification process is progressive, rational in infrastructure, the discarded object produced in purification process can not produce secondary pollution, practical, can greasy dirt, smog, dust particle, pernicious gas, peculiar smell etc. fast, efficiently, up hill and dale in asphalt flue gas purifying.
