The asphalt fume absorbing device includes an asphalt-fume catching air-suction shield port connected with the upper part of a dust-catcher dust collection hopper through a negative-pressure main pipeline, a main fan, a positive-pressure main pipeline and a tee pipe, which are connected in sequence; and an ash removing valve is arranged at the bottom of the dust-catcher dust collection hopper and connected with the tee pipe through a dust negative-pressure conveying pipeline, a circulatory small fan and a dust positive-pressure conveying pipeline, which are connected in sequence. The utility model has the benefits as follows: the capability of the main fan is performed, the maximization of air suction quantity in the sitefield is realized, and the continuous operation of sucking asphalt fumes and spraying dust absorption layers on a filtering bag can be realized, therefore, the asphalt fume absorbing device ensures not only the health of operating personnel on site, but also the pollution management control to tail fumes discharged into the air.
Description
Technical field
The utility model belongs to the technical field of the environmental protection installation in the plain production process of charcoal, is specifically related to a kind of bitumen flue gas adsorbent equipment.
Background technology
Pitch is one of primary raw material of producing carbon product, and the compositing formula cubage of pressing goods should occupy about 20-25%.Because the plain manufacturing technique requirent pitch of charcoal must have good flowability, so except that pitch is heated into the liquid state, also need temperature is remained between 150-170 ℃ constantly, under this temperature, bitumen flue gas can constantly be separated out volatilization from liquid bitumen, will not capture or capture effect in the operation area bad, will directly endanger the post operation personnel health, can not carry out efficient smoke-removing after the capture and purify, can cause environmental pollution again atmosphere.
What the plain manufacturer of the charcoal of China adopted the improvement of bitumen flue gas always is " suction type smoking absorption method ", be that smoking cover all places the preceding negative pressuren zone of Fan Inlet with the absorption bag dust collector that purifies usefulness, so, ventilation blower will be born two job tasks of suction bitumen flue gas and suction absorption dust simultaneously, and its result certainly will weaken the extraction amount to bitumen flue gas.Sometimes even more serious is when the absorption Dust Capacity that extracts is not enough to tackle the bitumen flue gas that needs purified treatment, also will closes suction bitumen flue gas fan housing, and extract the absorption dust specially.Nei result certainly will cause the post to do the on-the-spot phenomenon of not having ventilation of industry during this period of time.
Summary of the invention
The utility model has overcome the deficiency of existing " negative pressure smoking absorption method ", is a kind of negative pressure extracting bitumen flue gas, the method for malleation adsorption cleaning.Guaranteed both to accomplish to make suction bitumen flue gas and adsorption cleaning all when carrying out continuously, the negative pressure section that plays again at blower fan is being used to capture bitumen flue gas with the whole performances of the exhausting amount of blower fan, and in the malleation section of blower fan bitumen flue gas is carried out efficient purification effects.
The technical solution adopted in the utility model is as follows: the bitumen flue gas adsorbent equipment, comprise and capture bitumen flue gas draught hood mouth, capture the negative pressure section main line of bitumen flue gas draught hood mouth by linking to each other successively, main air blower, malleation section main line and three-way pipe are connected with deduster dust hopper top, deduster dust hopper top is provided with filter bag of dust collector, deduster dust hopper bottom is provided with ash-valve and the dust negative pressure transportation pipeline by linking to each other successively, circulate little blower fan and dust malleation transfer pipeline is connected with three-way pipe, is respectively arranged with control valve on negative pressure section main line and the dust malleation transfer pipeline.
One of feature of the present utility model: the negative pressure section before the main air blower inlet only is provided with the capture bitumen flue gas draught hood mouth of adsorptive pitch flue gas, and the malleation section after the main air blower outlet is provided with filter bag type deduster, ash ejector, the little blower fan that the adsorptive pitch flue gas is used.
Two of feature of the present utility model: owing to suction glance coal gas hood mouth only is set,, all be used in the extraction to the post bitumen flue gas, given full play to capture effect to bitumen flue gas so just with the exhausting amount that main air blower provided in blower fan negative pressure section.
Three of feature of the present utility model: on blower fan malleation section the bitumen flue gas that is captured is carried out the dust adsorption cleaning, the adsorption cleaning system is the periodic duty process of sealing.
The course of work of the present utility model is, at first dust is put in the deduster dust hopper, start little blower fan of circulation and the ash-valve that is located at deduster flue-dust retainer bottom, dust is recycled little blower fan suction after entering pipeline, boost through the little blower fan that circulates again, deliver to converge (three-way pipe) of the malleation section main line of main air blower and locate, enter filter bag of dust collector, and extension is attached on the inner chamber of filter bag of dust collector, when dust is long-pending when being laminated to certain thickness, starting main air blower is sent to bitumen flue gas in the deduster (comprising deduster flue-dust retainer and filter bag of dust collector), when bitumen flue gas passes through the filter bag dust layer, the flue gas particle is adsorbed by dust, and the clean tail gas after filtering passes through filter cloth and enters atmosphere.When dust and pitch mix particles layer run up to certain thickness, can be under the gravity effect, drop into successively in the deduster flue-dust retainer, discharge through ash-valve again, enter the work system of the little blower fan of circulation, and then be sent in the filter bag of dust collector and extension is attached on the filter bag of dust collector inner chamber, like this when main air blower aspirates bitumen flue gas all the time, the absorption dust and to the purification of bitumen flue gas also constantly carrying out of going round and beginning again.
The absorption of this device is used dry porous mass with dust, and as active carbon, coke powder etc., the dust granules diameter should be d=0.20～0.075mm.The existing relatively full suction type smoking absorption of the utility model is compared the advantageous effect that has and is, has brought into play the ability of main air blower, and the maximization of exhausting amount has been accomplished at the scene, post; Can realize aspirating bitumen flue gas and the continuously uninterrupted operation that filter bag is sprayed the dust adsorption layer.And then guaranteed post field operation personnel's health, also guaranteed tail gas is entered the pollution control control of atmospheric environment simultaneously.
