Description
Technical field
The present invention relates to a kind of environment-protective process and equipment, be specifically related to a kind of galvanizing zinc cigarette treatment process and system.
Background technology
In the galvanizing production technology, the zinc pot can produce zinc smoke waste gas pollutant, and this zinc smoke waste gas pollutant is mainly zinc oxide dust, for fear of contaminated environment, needs to collect the zinc cigarette and it is carried out purified treatment.
At present, the mode of galvanizing manufacturing enterprise collection and treatment zinc cigarette has:
1, side exhausting system: because the zinc cigarette temperature that galvanizing produces is high, the rate of climb is very fast, just bigger power of fan must be arranged so will collect the zinc cigarette preferably, and equipment purchase cost and operation energy consumption are higher;
2, mobile cover gathering system: owing to install and fix fan housing in driving, therefore soak the zinc inconvenient operation, the operating time is longer; Simultaneously since whole cover body weight all in driving, the weight that driving is born needs bigger; The inner surface that moves cover body needs often cleaning, and the seal between each parts needs time-based maintenance;
3, fixed cover gathering system: advantage is that collection efficiency is higher, can reach 95%, and its shortcoming is to drag for the slag difficulty, soaks the zinc inconvenient operation.
Summary of the invention
In view of this, the invention provides a kind of galvanizing zinc cigarette treatment process and system, the effective zinc cigarette that produces of collection and treatment zinc pot, and do not influence and soak the zinc operation, equipment purchase cost and operation energy consumption are low.
The invention discloses a kind of galvanizing zinc cigarette treatment process; End at the zinc pot blows the zinc cigarette that the zinc pot produces; The zinc cigarette that produces at the other end collected at suction zinc pot of zinc pot; Then the zinc cigarette of collected at suction is sent into spray purification tower, the zinc cigarette is discharged behind the shower water washing, purifying in spray purification tower.
Further, said shower water circulated sprinkling uses.
The invention also discloses a kind of galvanizing zinc cigarette treatment system; Comprise spray purification tower, air-introduced machine, hair-dryer, blowing mouth, gas skirt and exhaust chimney; Said blowing mouth is arranged on an end of zinc pot, and said gas skirt is arranged on the other end of zinc pot and relative with blowing mouth, and said hair-dryer is communicated with blowing mouth; Said gas skirt is communicated with spray purification tower through air-introduced machine, and said spray purification tower is communicated with exhaust chimney.
Further, also comprise shower water circulating pump and shower water circulatory pool, the inlet of said shower water circulating pump is communicated with the shower water circulatory pool, and outlet is communicated with the shower of spray purification tower, and said spray purification tower is communicated with the shower water circulatory pool.
Beneficial effect of the present invention is: the present invention adopts length to collect the zinc cigarette that the zinc pot produces to the mode of pressure-vaccum, then the zinc cigarette is sent into the spray purification tower washing, purifying and handles, owing in suction, combine to blow; Therefore can effectively collect the zinc cigarette that the zinc pot produces; And compare with the side exhausting system, power of fan is littler, and equipment purchase cost and operation energy consumption are lower; Simpler with duration to the pressure-vaccum pipe-line system; Can not influence and soak the zinc operation, the danger that can avoid quick-fried zinc to bring to the operator, near the noise that produces because of exhausting the zinc pot is also littler.
Description of drawings
In order to make the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that the present invention is made further detailed description below, wherein:
Fig. 1 is a process chart of the present invention;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below will carry out detailed description to the preferred embodiments of the present invention with reference to accompanying drawing.
Fig. 1 is a process chart of the present invention; As shown in the figure; Galvanizing zinc cigarette treatment process of the present invention blows the zinc cigarette that the zinc pot produces at an end of zinc pot, the zinc cigarette that produces at the other end collected at suction zinc pot of zinc pot; Then the zinc cigarette of collected at suction is sent into spray purification tower, the zinc cigarette is discharged behind the shower water washing, purifying in spray purification tower; The present invention is the characteristics of strip according to the zinc pot, adopts length to collect the zinc cigarette that the zinc pot produces to the mode of pressure-vaccum, owing in suction, combine to blow; Therefore can effectively collect the zinc cigarette that the zinc pot produces, and compare with the side exhausting system, power of fan is littler; Equipment purchase cost and operation energy consumption are lower, and be simpler to the pressure-vaccum pipe-line system with duration, can not influence to soak the zinc operation; Near the noise that produces because of exhausting the danger that can avoid quick-fried zinc to bring to the operator, zinc pot is also littler.
In the present embodiment, said shower water circulated sprinkling uses; The additional in good time and replacing of shower water, the shower water of replacing enters plant area's Waste Water Treatment and handles the back reuse, and contains a large amount of ZnCl in the glar that obtains behind the spray absorption zinc cigarette
2, ZnO, therefore can collect and dry the back and form zinc gray, utilize extracting zinc once more.
Fig. 1 is a process chart of the present invention; Fig. 2 is structural representation of the present invention, and is as shown in the figure, galvanizing zinc cigarette treatment system of the present invention; Comprise spray purification tower 1, air-introduced machine 2, hair-dryer 3, blowing mouth 4, gas skirt 5 and exhaust chimney; Said blowing mouth 4 is arranged on an end of zinc pot 6, and said gas skirt 5 is arranged on the other end of zinc pot 6 and relative with blowing mouth 4, and said hair-dryer 3 is communicated with blowing mouth 4; Said gas skirt 5 is communicated with spray purification tower 1 through air-introduced machine 2, and said spray purification tower 1 is communicated with (not drawing among Fig. 2) with exhaust chimney; Hair-dryer 3 blows the zinc cigarette that zinc pot 6 produces through blowing mouth 4 at an end of zinc pot 6; The other end at zinc pot 6; The zinc cigarette that gas skirt 5 collected at suction zinc pots 6 produce; Then the zinc cigarette of collected at suction is sent into spray purification tower 1 through air-introduced machine 2, the zinc cigarette is discharged through exhaust chimney behind the shower water washing, purifying in spray purification tower 1.
