Abstract
The invention discloses a sealing device for isolating among air chambers of a dust collector. The sealing device comprises a cleaning chamber at the upper part of a dust collector body, and a filtering chamber on which dust-containing coalification gas is introduced, wherein a supporting and sealing structure is arranged between the cleaning chamber and the filtering chamber; the supporting and sealing structure comprises a supporting board, an isolation board and annular sealing boards, which are connected in sequence; the annular sealing boards are fixedly connected with the isolation board and the dust collector body; reserved cavities are formed between the annular sealing boards and the supporting board; annular grooves are formed in the supporting board; packing sealing cushions are arranged inside the annular grooves. According to the sealing device provided by the invention, the reserved cavities are formed between the annular sealing boards and the supporting board, so that a space is provided for the outward extending of the isolation board caused by the expansion in a high-temperature condition, and the problem that the traditional hard-connection sealing effect is poor is avoided. Specially, the annular sealing board is prepared from an elastic material, so that the annular sealing board is subject to adaptive deformation with the expansion of the isolation board well; the entire isolation and sealing effects are optimal by combining the auxiliary sealing of the packing sealing cushions.
Description
Technical field
The invention belongs to filter element of duster cleaner technical field, particularly isolation sealing device between a kind of deduster air chamber.
Background technology
At present, at chemical industry, oil, the industries such as metallurgy often produce high-temperature dusty gas, because different process need to carry out dedusting to high-temperature dusty gas, realize gas solid separation and gas purification, what often use is to be filtered and realized gas solid separation by the filter core in deduster, through the dusty gas filtering, enter air-purifying chamber, in dusty gas, a large amount of dust is stayed in the filter chamber of filter core outside after being filtered, carrying out along with filter process, the filter core that deduster is used its outer surface in dust removal by filtration process can adsorb a large amount of granule dusts, along with dust is constantly increased accumulation, sedimentation is store grey chamber and is discharged from bottom.But in use procedure because the dusty gas passing into has higher temperature and pressure, particularly when the dust-laden coalification gas to containing coal tar composition carries out dust removal and filtration, must keep higher temperature to cause filter core use extremely even to scrap to prevent that coal tar condensation is bonded on filter element of duster, but deduster is all cold state monitoring when handing over, so under the high-temperature high-pressure state of normal work, the clean room and the isolating seal between filter chamber that often occur described deduster lost efficacy, cause local dust-laden coalification gas leakage to enter clean room, the air-purifying chamber that dust enters deduster will removing pollutant gas be brought subsequent handling into and is caused great loss, affect the efficient treatment process of whole coal dust.The seal means adopting is at present various, has plenty of division board is welded on the supporting plate on described deduster inwall; Also there are both bolts to connect, centre adds sealing gasket, but wait in use due to high-temperature expansion, described division board expands deformation, losing efficacy in various degree appears in weld and bolt link position, therefore sealing effectiveness is bad, often occurs the phenomenon that dust-laden coalification gas leakage enters clean room, and impact is normally produced.Therefore, need badly and between the air chamber of deduster, isolate position and make further improvement and bring new ideas and solve the problems referred to above, but common deduster is all that conventional bolt connects firmly at present, comparatively suitable technology is open.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide a kind of can fast dust-removing, isolation sealing device between the good deduster air chamber of ash-removal effect.
For achieving the above object, the technical solution used in the present invention is: isolation sealing device between a kind of deduster air chamber, the clean room and the filter chamber that passes into dust-laden coalification gas that comprise deduster body top, support hermetically-sealed construction is set between described clean room and filter chamber, described support hermetically-sealed construction comprises supporting plate, division board and the annular seal plate connecting in turn, described annular seal plate is fixedly connected with deduster body with described division board respectively, forms reserved cavity between described annular seal plate and described supporting plate.
On described supporting plate, cannelure is set, packing_seal pad is set in described cannelure.
Described cannelure is set to many groups.
