Description
Technical field
The utility model relates to a kind of big caliber gas filtration net arrangement of easy disassembly, particularly a kind of can convenient dismounting the big caliber low-pressure inlet of large-scale gas centrifugation formula compressor filter screen device.
Background technology
At big flow, on the high-power gas boosting equipment pipe, particularly produce 300000 tons of synthetic ammonia per year in beautiful (lotus) type, during gas filtration on the large centrifugal carbon-dioxide gas compressor group low pressure (LP) cylinder inlet duct in the large-scale nitrogen fertilizer plant urea plant that urea is 48 tons, the ingress filtering net is contained in the junction of cylinder body inlet and inlet tube regularly, stay the rigid elbow of having established 90 degree on its fairlead and reach 16 meters, thick 680 millimeters of caliber, long tube more than two tons weighs, dismounting is wasted time and energy extremely inconvenient quick, exists the maintenance that is not easy to when going into operation operation, check, the shortcoming of cleaning.Simultaneously, a certain amount of impurity deposition knot year in year out blocks up carbon-dioxide gas compressor low pressure (LP) cylinder screen pack wire side because of carbon dioxide contains, make the flow area of screen pack wire side fewer and feweri, through-current capability is more and more lower, cause the soakage wretched insufficiency, and cause the surge of low pressure (LP) cylinder, unit can not be brought into play optimum condition, can not the raising speed dosage in the production, limited the normal operation of producing.
Stifled in order to solve screen pack wire side knot; cause the soakage deficiency; cause the unit surge; can't start shooting and the problem of ordinary production operation; the user who has offers a manhole at this pipeline middle part; but practice shows; this method also exists needs to shut down stopping production; opening conduits middle part cover plate for manhole after the decrease temperature and pressure; must send on the chemical industry band long tube formula breathing mask to enter and manually clean wiper in the pipeline; owing to spatial constraints and screen pack in the pipe are inverted cone-shaped structure, old friend worker clears up wiper difficulty very, and is absolutely unsafe with thorough; up to the present, this problem still is not resolved.
Summary of the invention
The purpose of this utility model provides a kind of big caliber gas filtration net arrangement of easy disassembly, particularly provide a kind of can convenient dismounting the big caliber low-pressure inlet of large-scale gas centrifugation formula compressor filter screen device.
The purpose of this utility model realizes in the following way: conical filtering net web-roll core, the circular cone side is provided with the web-roll core skeleton, on have by rounded projections arranged, the aperture is 8 through holes to millimeter, its hole count can reach up to ten thousand, the gross area in hole should be 3.5 times of the caliber cross-sectional area with on 10, the web-roll core skeleton is provided with screen cloth outward, to constitute effective gas filtration net; The annulus of conical bottom and inboard connection of the awl end, several corresponding bolts of boxing out with cylinder top are set on the annulus, so that form the fast-assembling design of the convenient dismounting of energy, one of cylinder is connected with the butt joint of cylinder body flange joint annulus, and be drilled with uniform through hole, constitute the fast-assembling design tangerine structure that can conveniently dock with the screen pack web-roll core, the other end is provided with the manhole and the screen pack web-roll core flange of energy easy disassembly, and with bolted flange plate.
Adopt the utility model, can receive following effect: be better than intrinsic fixedly pattern, can convenient dismounting, made things convenient for inspection, cleaning to reach replacing dismounting at usefulness and standby filtration web-roll core, guarantee the wire side cleaning, gas communication is smooth and easy efficient, makes the operating mode of unit can be in more excellent better working environment, practicality better effects if for a long time.
Avoided original and need to shut down stopped production, sent chemical industry to enter the working environment of the difficulty that the cleaning wiper is faced in the pipeline again after the decrease temperature and pressure and the suffocate accident potential of the casualties of the carbon dioxide that may therefore cause.
Permanently solved the defective that difficulty is torn open, difficulty is clear, difficulty is adorned, difficulty is started shooting and produced; guaranteed that unit reaches optimal operating condition to greatest extent; make in the unit start running raising speed dosage random freely; the machine halt trouble that minimizing causes because of screen pack; improve to greatest extent that urea production and operation produce long period, all received remarkable and huge economic benefit and social benefit.
(pulling down cleaning) and standby (new web-roll core or cleaning back are standby) filtration web-roll core is being used in convenient dismounting; guarantee that the screen pack wire side cleans, efficient, unimpeded and sufficient soakage is blocked up the technical barrier that difficulty is torn open, difficulty is adorned, difficulty is clear, difficulty is started shooting successfully to solve this screen pack wire side because of the impurity knot; solved the technical barrier that causes surge of soakage deficiency and low yield, shutdown because of screen pack wire side knot is stifled, realized that the carbon-dioxide gas compressor group is left, the long-term steadily anticipation purpose of high-quality of shutdown and ordinary production operating condition.
