Description

Isolation sealing device between a kind of deduster air chamber
Technical field
The invention belongs to filter element of duster technical field of dust removal equipment, 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 needs to carry out dedusting to high-temperature dusty gas, realize gas solid separation and gas purification, often use and carry out filtration by the filter core in deduster and realize gas solid separation, dusty gas through filtering enters air-purifying chamber, stay in the filter chamber of filter core outside after dust a large amount of in dusty gas is filtered, along with the carrying out of filter process, filter core its outer surface in dust removal by filtration process of deduster 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 the dusty gas owing to passing in use procedure has higher temperature and pressure, particularly when carrying out dust removal and filtration to the dust-laden coalification gas containing coal tar composition, higher temperature must be kept to cause filter core use extremely even to scrap to prevent coal tar condensation to be 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, isolating seal between the clean room of the described deduster of frequent appearance and filter chamber lost efficacy, local dust-laden coalification gas leakage is caused to enter clean room, the air-purifying chamber that dust enters deduster will be brought subsequent handling into and causes great loss by removing pollutant gas, affect the efficient treatment process of whole coal dust.The seal means of current employing is various, has plenty of and division board is welded on the supporting plate on described deduster inwall; Also both bolts are had 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 that dust-laden coalification gas leakage enters the phenomenon of clean room, and impact is normally produced.Therefore, need badly and between the air chamber of deduster, to isolate position make further improvement and bring new ideas and solve the problems referred to above, but deduster common is at present all conventional bolt Hard link, comparatively unsuitable 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 isolation sealing device between fast dust-removing, ash-removal effect good deduster air chamber.
For achieving the above object, the technical solution used in the present invention is: isolation sealing device between a kind of deduster air chamber, comprise the clean room of deduster body upper part and pass into the filter chamber of dust-laden coalification gas, support hermetically-sealed construction is set between described clean room and filter chamber, described support hermetically-sealed construction comprises the supporting plate, division board and the annular seal plate that connect 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.
Described supporting plate arranges cannelure, packing sealing gasket is set in described cannelure.
Described cannelure is set to many groups.
Described packing_seal pad is selected graphite packing or is strengthened graphite packing.
Arrange backing plate between described supporting plate and described division board, described backing plate is connected with division board bolt.
Described backing plate top arranges top board, and described top board Inner holds and leaves gap with described division board outward flange.
Described top board is briquetting bolted with described supporting plate.
Described backing plate the inner arranges the riser simultaneously covering described supporting plate.
