Abstract
A two-stage integrated high temperature gas purifier system comprises a first stage shell and a second stage shell; the upper part of the first stage shell the first stage is provided with a gas inlet; the first stage shell is provided with a guide post; the two shells are communicated by a prestage exhaust pipe; bottoms of the two shells are provided with dust discharge openings; a filter support plate on the upper part of the second stage shell is provided with a filtering tube through a heat insulation and connecting piece; a back blowing device is arranged above the filtering tube; a gas supply system is installed outside the first stage shell; and a gas outlet is arranged on the upper part of second stage shell. During working, dust-containing gas enters into the first stage shell from the gas inlet tangentially and rotates around the guide post downwards; coarse particles are isolated and discharged in the gas rotation process; the rest of the gas subjected to the first stage coarse filtration enters the second stage shell through prestage exhaust pipe for reaction, and is ultimately discharged from the gas outlet. The tar treated by the invention has high purity and good quality, and is easy to carry out subsequent in-depth finish machining.
Description
Technical field
The present invention relates to high temperature gas cleaning technical field, particularly a kind of two-stage integrated formula high temperature gas cleaning device system, is mainly applicable to the high temperature gas cleaning of the industries such as Coal Chemical Industry, coking and oil shale pyrolysis.
Background technology
In the technical process such as the pyrolysis operation of coal, oil shale or oil-sand, in pyrolysis gas, often contain tar to be separated, but also contain a large amount of solia particles to be removed simultaneously.Mostly current existing treatment process is just to carry out cooling to high temperature pyrolysis gas before not removed solia particle, part tar condensing is separated, meanwhile also a large amount of solia particles are sneaked in isolated tar in the lump, not only reduce thus the quality of tar, brought difficulty also to the follow-up deep processing of tar.
Summary of the invention
In order to overcome the deficiency of above-mentioned treatment process technology, the present invention proposes a kind of two-stage integrated formula high temperature gas cleaning device system, can make high-temperature gas first remove solid particle by this clarifier, tar condensing is separated gas cooled more afterwards, the tar of processing like this, high purity, quality better, is easy to carry out follow-up degree of depth fine finishining.
In order to achieve the above object, technical scheme of the present invention is:
A kind of two-stage integrated formula high temperature gas cleaning device system, comprise first order housing 1, first order housing 1 top, side has gas access 12, first order housing 1 inside top is provided with diversion column 2, first order housing 1 is communicated with by prestage blast pipe 3 with second level housing 11, first order housing 1 is provided with ash discharging hole 4 with second level housing 11 bottoms, be provided with filter gripper shoe 10 on second level housing 11 tops, in filter gripper shoe 10, by heat insulation and connecting piece 7, screen pipe 6 is installed, blowback device 8 is installed above screen pipe 6, air supply system 9 is arranged on first order housing 1 outside, housing 11 tops in the second level are provided with gas vent 14, first order housing 1 supports fixing with second level housing 11 by support 5.
On first order housing 1 and second level housing 11, be provided with heat insulation and wearing layer 13.
Being complex as a whole of double-filtration structure of the present invention, gas flow process is short, the heat insulation and wearing layer 13 on housing in addition, the temperature drop minimum can make process gas flow through system time, can prevent that gas temperature is too low and tar is separated out stop up chimney filter and pipeline; Dusty gas first passes through first order coarse filtration, removes coarse granule and enters second level essence filtration afterwards again, has greatly alleviated the burden of second level chimney filter, has reduced the gas flow of chimney filter reverse gas cleaning, has reduced the impact on Purge gas.
The present invention is equally applicable to not contain the purification of the high-temperature gas of tar gas, can make gas qualified discharge.When for gas at normal temperature, the insulating on housing can save and will not lay.
Brief description of the drawings
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
With reference to accompanying drawing, a kind of two-stage integrated formula high temperature gas cleaning device system, comprise first order housing 1 (containing heat insulation and wearing layer 13), diversion column 2, prestage blast pipe 3, ash discharging hole 4, support 5, screen pipe 6, heat insulation and connecting piece 7, blowback device 8, air supply system 9, screen pipe gripper shoe 10, second level housing 11 (containing heat insulation and wearing layer 13);
First order housing 1 top, side has gas access 12, first order housing 1 inside top is provided with diversion column 2, first order housing 1 is communicated with by prestage blast pipe 3 with second level housing 11, first order housing 1 is provided with ash discharging hole 4 with second level housing 11 bottoms, be provided with filter gripper shoe 10 on second level housing 11 tops, in filter gripper shoe 10, by heat insulation and connecting piece 7, screen pipe 6 is installed, blowback device 8 is installed above screen pipe 6, air supply system 9 is arranged on first order housing 1 outside, housing 11 tops in the second level are provided with gas vent 14, first order housing 1 supports fixing with second level housing 11 by support 5.
Operation principle of the present invention is: when work, dusty gas tangentially enters first order housing 1 by gas access 12, is rotated down, around diversion column 2 under centrifugal action, be greater than 10 microns of above coarse granules and be separated in gas rotating process, and discharged by bottom ash discharging hole 4; Remaining enters the bottom of second level housing 11 again via prestage blast pipe 3 through the gas of first order coarse filtration, in the process of moving upward, through one group of screen pipe 6 being fixed in screen pipe gripper shoe 10, be greater than 1 micron of above particle and be filtered pipe 6 obstructs at outer tube surface, purified gas, via screen pipe 6 inside, is finally discharged by gas vent.Be arranged in the anti-blowpipe 8 on second level housing 11 tops, under the control of air supply system 9, be periodically blown into the hot gas of certain pressure to screen pipe 6 inner surfaces.Under the effect of blowback power, the particle detachment that is deposited on screen pipe 6 outer surfaces downwards and discharged by ash discharging hole 4.
