Abstract
The utility model discloses a novel coal gas filtration and purification device. A section of a gas duct water cooling pipe, a cyclone dust collector and an air cooler are arranged in front of a dust remover of a closed furnace; raw coal gas enters the gas duct water cooling pipe, the cyclone dust collector and the air cooler sequentially; an expansion joint is arranged at the front end of the gas duct water cooling pipe; an outlet of the air cooler is connected with an ash bucket gas inlet of the dust remover of the closed furnace; and an outlet of the dust remover of the closed furnace is connected with a booster fan. The novel coal gas filtration and purification device is applicable to blast furnace coal gas bag type dedusting; the high-temperature raw coal gas can be cooled to the temperature of 200 DEG C below; the problem that a bag of a conventional dust remover cannot resist a high temperature is solved; and the service life is prolonged, the production cost is reduced, and the security coefficient is increased.
Description
Technical field
The utility model relates to a kind of novel gas filtering and purifying, belongs to gas purification dedusting technology field.
Background technology
The gas purification dedusting is a new technical barrier, the flue dust that contains a large amount of coal tar and cotton-shaped viscosity in raw gas, and raw gas temperature is higher, generally reach 400-500 ℃, raw gas is inflammable and explosive, should not adopt conventional method for dust removal, also contains BSO and BaP in raw gas simultaneously, contaminate environment, be detrimental to health.Treatment process commonly used is: raw gas introduced in the sealed furnace fly-ash separator and carried out dedusting by pipeline, but this method existent defect, and the one, dust-collecting bag can't resistant to elevated temperatures problem, and work-ing life is limited, and replacement cost is higher; Owing to only using bag-type dust, in raw gas, the macrobead flue dust is larger to the cloth bag abrasive action in addition, easily causes cloth bag to damage, and causes efficiency of dust collection to descend.
The utility model content
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of novel gas filtering and purifying, raw gas is lowered the temperature, the tornado dust collector pre-treatment, again by air cooling, then entering the dedusting of sealed furnace fly-ash separator, is a kind of novel, simple and convenient, efficiently flue gas conducting dust-removal system.
The utility model technical solution problem adopts following technical scheme:
A kind of novel gas filtering and purifying, it is characterized in that, first be provided with a telescopic joint on the raw gas transport pipe, raw gas enters tornado dust collector after the flue water cooling tube, enter air-cooler and sealed furnace fly-ash separator through pipeline again, described tornado dust collector are connected by cleaning shaft with air-cooler and sealed furnace fly-ash separator, also be provided with the nitrogen injection deashing device on described sealed furnace fly-ash separator, described flue water cooling tube front end arranges telescopic joint, and the bottom of described tornado dust collector is provided with ash bucket and is located at the unloading valve of ash bucket bottom; The bottom of described sealed furnace fly-ash separator is provided with ash bucket and is located at the unloading valve of ash bucket bottom, and top is provided with the nitrogen injection deashing device.
[0005]compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is transformed traditional sealed furnace fly-ash separator; increase telescopic joint and can effectively prevent that pipeline from damaging because expanding with heat and contract with cold on cleaning shaft; the flue water cooling tube that first process newly increases before raw gas enters the sealed furnace fly-ash separator, by cooling high-temperature fume, the protection cloth bag.Raw gas can effectively be removed the macrobead flue dust through tornado dust collector, reduces greatly the abrasion of dust to cloth bag.Further lower the temperature by air-cooler, raw gas temperature can be down to below 200 ℃, making up existing dust-collecting bag can't resistant to elevated temperatures problem, increases the service life, and reduces production costs, and improves safety coefficient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1 cleaning shaft, 2 telescopic joints, 3 flue water cooling tubes, 4 tornado dust collector, 5 connecting tubes, 6 air-coolers, 7 pipe connectings, 8 sealed furnace fly-ash separators, 9 gas exit pipelines, 10 fly-ash separator bottom discharge valves, 11 tornado dust collector bottom discharge valves, 12 nitrogen soot cleaning systems.
Embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated, yet described embodiment can not be used for limiting scope of patent protection of the present utility model only for furnishing an explanation and the use of explaining.
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As Fig. 1, a kind of novel gas filtering and purifying,, by cleaning shaft 1, raw gas is delivered to dust removal installation, be provided with telescopic joint 2 on cleaning shaft 1, flue gas enters flue water cooling tube 3 and carries out coolingly, then enters tornado dust collector 4 and removes most of flue dust, enter again air-cooler 6 by connecting tube,, raw gas enters sealed furnace fly-ash separator 8 from air-cooler 6 bottoms by pipe connecting, after bag-type dust, by gas exit pipeline 9, is exported again.
In conjunction with Fig. 1, raw gas has very high temperature, allow raw gas can effectively reduce its temperature through flue water cooling tube 3, the tornado dust collector bottom is provided with discharge valve 11, in raw gas, a large amount of dust settle down after tornado dust collector 4, can accumulate in its underpart, by the regular deashing of discharge valve 11, raw gas is after air-cooler 6 is further lowered the temperature, can reach the working condition requirement of sealed furnace fly-ash separator 8, after the operation of for some time, the dust of dust collector ash hopper inner accumulated can be got rid of by bottom discharge valve 10.Dust on cloth bag can increase systemic resistance, every operation for some time, can carry out jetting deashing by nitrogen soot cleaning system 12, and reduce the dust on cloth bag.The utility model can effectively solve existing dust-collecting bag can't resistant to elevated temperatures problem, extends cloth bag work-ing life, reduces production costs, and improves safety coefficient.
