Description
Technical field
The present invention relates to industrial waste gas purifying field, and in particular to a kind of cleaning equipment for waste organic gas (system), especially fits
For product of rubber and plastic and the waste gas purification of glass wool product.
Background technology
Industrial organic waste-gas purification device in conventional art is combined by multiple kitchen fume processors, due to work
Industry production waste gas discharge capacity is big, and treatment effect is not obvious, and needs often cleaning, and operation difficulty is quite big during cleaning.Cause big
Part pernicious gas is discharged into the air, pollutes environment.
The content of the invention
The purpose of the present invention is intended to overcome the deficiencies in the prior art, by improving, increasing exhaust air treatment plant, effectively purification
Industrial waste gas.
The technical scheme is that improving waste gas cleaning system, increase gas and oil separating plant, and gs-oil separator is caught
Catch pole shape and connected mode is improved, can effectively purify waste gas, regenerant can also be recycled.
Industrial waste-gas purifier of the present invention includes：Admission line, water cooling system, mud chamber, waste gas adjuster top,
Waste gas adjuster bottom, gs-oil separator, blast pipe.
Technical scheme is applied to the purification of various oil gas and organic volatile.
The present invention is especially suitable for product of rubber and plastic and the waste gas purification of glass wool product.
The waste gas adjuster top is usually 1500~2000 holes, preferably 1700~1900 holes.
The waste gas adjuster top aperture is 30~100 ㎜, preferably 50~70 ㎜.
The vertical waste gas regulation pipeline of one horizontal stroke of waste gas adjuster bottom increase by three, pipeline intercommunication, the vertical waste gas of the horizontal stroke of increase by one three
Pipeline is adjusted, supervisor, branch diameter and opening diameter and quantity are determined according to waste gas total amount, supervisor's flow velocity, and takes and contracts as far as possible
Short waste gas adjuster lower pipeline entrance point and three vertical waste gas adjust the length of pipe outlet, the side for making drag losses minimum
Formula, makes waste gas arrangement more uniform.
The ㎜ of waste gas adjuster bottom waste gas regulation pipeline predominant tube diameter 1200~1600；It is preferred that 1350~1500 ㎜,
The upper rows of openings of EDS maps one, bore dia is 70~130 ㎜, preferably 90~110 ㎜.
The waste gas adjuster bottom waste gas adjusts pipeline branch pipe a diameter of 500~750 ㎜, preferably 580~700 ㎜, puts down
Row is uniformly distributed three rows of openings, and bore dia is 70~130 ㎜, preferably 90~110 ㎜.
The waste gas adjuster lower pipeline entrance point length is usually 900~1100 ㎜.
Described three vertical waste gas regulation pipe outlet length are usually 1400~1900 ㎜.
The gs-oil separator is comprising seizure pole and excites pole.
Ultimate ratio is excited to catch extremely a length of 1.5~2.0 meters.And the gs-oil separator of prior art excites ultimate ratio seizure extremely long
1.0 rice.Gs-oil separator is difficult electric discharge after improvement, effectively raises voltage, and seizure pole does not produce and smoldered.
It is described to excite pole to be commonly installed wire electrode 300~600, preferably 340~560.After wire electrode quantity increase, increase
Large electrode silk and the contact surface of waste gas, so as to increase treating capacity, clean-up effect is more preferable.
The seizure pole and exciting sets up 4.0~7.5 ten thousand volts of electric field between pole, compared with prior art 4.5~6.0 ten thousand volt
Field regime it is bigger, be easy to rationally utilize electric energy, when treating capacity is small, set up compared with existing fringing field, reduce energy waste, work as processing
When measuring big, higher electric field is set up, treatment effect is improved.
The gs-oil separator catches pole and excites the electric field no load test between pole to be more than 7.2 ten thousand volts.
Handle the Nm of air quantity 6.5 ten thousand3During/h, the gs-oil separator catches pole and excites the electric field highest between pole to work electric
Press 6.5 ten thousand volts；Handle the Nm of air quantity 5.5 ten thousand3During/h, 50,000 volts of maximum operating voltage.
The gs-oil separator is usually 300~600 holes, preferably 340~560 holes.
The gs-oil separator catches extremely hexagon, one-off drawing shaping, i.e., with hexagon mould (internal model, external mold) essence
Close fit, by the hexagon steel tubes (note after heating：About 4 millimeters of blank thickness of pipe wall) it is drawn into satisfactory seizure pole
(about 2 millimeters of finished product wall thickness), catches and is brought into close contact between pole, upper and lower ends screw connection, full of whole tank body, catch pole it
Between there is no gap.And usual use between two triangle butt welding in spot, each side of prior art has gap generation；Or use six sides
Shape is arranged in parallel, there is the gap assumed diamond in shape between hexagon, and causing gas leakage to cause, waste gas arrangement is uneven, and portion does not pass through place
Reason is directly outer to arrange, and exhaust-gas treatment effect is poor.
The gs-oil separator catches pole hexagon opposite side a diameter of 50~450 ㎜, preferably 150~300 ㎜.
About 15 meters of waste gas purification apparatus total height of the present invention, about 6~7 meters of diameter.
Waste gas enters after water cooling system cooling from air inlet pipe, and gs-oil separator, oil gas are entered back into by waste gas adjuster
The seizure pole of separator and exciting sets up 4~7.5 ten thousand volts of electric field between pole, and corona discharge is produced between the two poles of the earth.Originally
When the gas of dust-laden and oils droplet after step cooling is by the space, dust and oils droplet be polarized it is powered, to catching pole
It is mobile, encounter seizure and be extremely attached to afterwards on seizure pole pipe wall, separator bottom is sunk to because of deadweight, into mud chamber.Sediment is determined
Phase clears up, and is recycled.
The present invention has the advantages that relative to prior art：
1. gs-oil separator rated voltage 4.0~7.5 ten thousand volt, catch pole and do not produce and smolders, service life is longer, efficiency compared with
Height, can remove and be more than 95% oils and dust and volatile matter.
2. gs-oil separator of the present invention catches extremely hexagon, one-off drawing shaping, seizure does not have gap between pole, makes to give up
Gas arrangement is uniform, and exhaust-gas treatment effect is good.
3. non-methane hydrocarbon emission concentration≤3.76mg/m after present invention purification product of rubber and plastic waste gas3, it is much better than state's scale value
80mg/m3, hydrogen sulfide emission amount≤0.014 ㎏/h is much better than state 2.3 ㎏ of scale value/h.
4. the present invention utilizes recycling precipitate, environmental pollution is both reduced, product cost can be reduced again.
