The embodiment of the present invention is when work: the waste gas that smelting furnace produces is cooled by cooler, then enter cyclone settling bucket to carry out once filtering waste gas, the import that dusty gas enters pulse bag formula deduster is again introduced into a bag air channel, room, then ash bucket is entered, now air velocity reduces, direction changes, and thicker grit reaches pre-dust collection effect because inertia and natural subsidence enter ash bucket; Then gas rises through filter bag and is purified, and dust is delayed on filter bag outer surface, and purified gas is discharged through filter bag, air-purifying chamber, exhaust outlet under the effect of air-introduced machine.
Deashing and automatically control: after deduster filtering gas reaches the regular hour, namely dust cleaner control system sends signal, carries out deashing.During deashing, the lift valve of first case room cuts out to cut off filtered airflow, then this room pulse valve is opened, air-purifying chamber is entered with 0.5-0.7MPa compressed air spraying, the opening time of pulse valve can adjust according to dust concentration and air consumption, general control between 0.1-0.25 second, after 6-15 second, deashing terminates, lift valve reopens, and this room returns normal dedusting duty, and first case room deashing terminates; After the several seconds of interval, second case room starts deashing, repeats the action of first case room.Complete machine deashing locellus carries out, and overall process is automatically controlled by the program preset, time (can revise) or Non-follow control operates.
Illustrating: the filtration velocity in table can be adjusted accordingly according to the dust concentration in flue gas, dust characteristic, suitably can improve filtration velocity when processing the low and dust of easy-to-clean ash of entrance concentration, increase process air quantity; When using coated filter material, also filtration velocity can be improved; Air supply required when compressed air consumption is dust-precipitator entrance concentration > 500g/Nm3.
Important technological parameters:
Operational procedure:
1, stove baker stage and other probable to aware, run duration that large quantity of moisture may be carried under one's arms in flue gas, the cloth bag in sack cleaner all must be taken off, otherwise cloth bag may be caused to damage due to factors such as condensation.
2, the running temperature of sack cleaner is with reference to cloth bag media performance parameter list, as running temperature exceedes allowable temperature, then can burn cloth bag; As running temperature continues too low, then may produce dew condensation phenomenon and cause cloth bag to corrode.(height entering the flue-gas temperature of deduster is controlled by gas cooler and the pipeline that leaks informaton)
3, sack cleaner run through pulse control instrument to control (setting of pulse control instrument is operated by instrument work).Cloth bag operation process flow process:
(controller brings into operation) → stop valve cut out → pulse valve blowing → stop valve that switches on power promotes → enters second unit and runs, and repeats first module action.
5, before furnace flue gas enters deduster, operating personnel open the power supply of pulse control instrument, make controller enter duty; Need the duty of Monitor and Control instrument whether normal in running.
4, operative employee's inlet and outlet pressure that need record sack cleaner per hour is poor, and normal condition at about 1500-1700Pa, if pressure differential has the trend of rising, then should will notify pulse spacing and the winding-up time of instrument work adjustment controller.
6, after flue gas stops entering sack cleaner, after air-introduced machine stops completely, controller dump.
7, sack cleaner is stopped transport for a long time, and the stop valve that manually operation handlebar is all cuts out, and circulates in dedusting gas to intercept extraneous air; And upper box body inspection cloth bag situation is opened in timing, produces, then need cloth bag to take off, deposit in dry part if any dew condensation phenomenon.
Key points for operation: flue-gas temperature, inlet and outlet pressure be poor, prevent condensation
Cloth bag filtrate physical and chemical performance table:
First to confirm the filtrate employing which kind of material in deduster before using sack cleaner operation in the past, then control by the filtrate characteristic of this table, should be noted that especially and control temperature well, very easily burn out cloth bag.By cooler and cyclone settling bucket, effectively reduce flue-gas temperature, the common material of current use: terylene needled felt, greatly reduces production cost.
