Fig. 3 is the low pressure fast-pulse spraying and blowing organ schematic diagram that converter gas dry method of the present utility model purifies sack cleaner.Low pressure fast-pulse spraying and blowing organ in the present embodiment divides the winding-up pipe 34 of gas tank 33 and band convergent shape nozzle to form by submerged pulse valve 32, big volume.Pulse valve 32 is inlaid in the end face that gas tank 33 is divided in the square-section, and valve port 43 floods wherein.Valve port is inserted on winding-up pipe 34 tops, with 42 sealings of zero shape circle; The bottom is welded, is fixed with dividing the gas tank bottom surface; End is connected by the winding-up transverse tube of bend pipe with band convergent shape nozzle 45.By the action of control main film 44, discharge compressed air to realize pulse jetting deashing.Because pulse valve is submerged and quick feedback throttle orifice 41, big, the winding-up pipe racks convergent shape nozzle of branch gas tank reservoir volume is arranged, improved the flow behavior of spraying and blowing organ, so the winding-up bleed pressure is by being reduced to 0.2～0.3MPa more than traditional 0.5MPa.Each pulse valve winding-up time once is about 100 milliseconds.
Fig. 4 is that two buckets, two valve dust removing systems and middle ash bucket erecting by overhang of coal gas of steel-smelting revolving furnace with dry method pocket type purification recovery system of the present utility model are below in conjunction with accompanying drawing.For preventing that air from bleeding, dust removing system adopts two buckets, two-valve arrangement, and as shown in Figure 4, two buckets, two block of valve device of air are by big ash bucket 40 and middle ash bucket 8, and ball valve 7 and ash envelope valve 9 are formed tight air-lock device, and described ash envelope valve 9 can be pipe spiral ash envelope valve.Big ash bucket 40 and dedusting cylindrical shell 11 are wholely set, and are connected with middle ash bucket 8 by pneumatic ball valve 7, and the outlet of middle ash bucket 8 connects ash envelope valve 9, and its both evenly discharging of pipe spiral can be used as air-tightness ash envelope valve again and uses.Middle ash bucket erecting by overhang is made up of stud 46, hanger 48 and butterfly spring 47, to the redeeming of expanding with heat and contract with cold.The outlet of this centre ash bucket connects dust air-transport system 39 to grey storehouse.
For preventing ash bucket inwall counter tide, dust bonding, at the conical section of big ash bucket and middle ash bucket the steam pipe coil heating is set, cylindrical shell and pipe section coat insulation with heat-insulating material.
The operation principle that converter gas dry method of the present utility model purifies sack cleaner is: raw coke oven gas inserts from being responsible for 10, through control valve 15b (for example, this control valve 15b can be Hand-operated butterfly valve), blank-plate valve 16, raw coke oven gas arm 37 and airflow uniform distribution outlet 29 blow out to ash bucket 40.When coal gas was turned back upwards, coarse granule was thrown out of, and fine dust is with air-flow trend filter bag 35.When raw coke oven gas passes, dust is delayed on the filter bag outer surface, purified gas after the filtration comes together in the purified gas space of card more than 31, then (for example through purified gas arm 30, blank-plate valve 16 and control valve 15a, this control valve 15a can be Pneumatic butterfly valve), be responsible for 17 through pure qi (oxygen) again and flow into next operation.
Along with increasing of filter bag outer surface dust quantity, the deduster running resistance rises, and when reaching the setting value higher limit, robot control system(RCS) begins branch tube off-line ash-clearing automatically.Its process is, closes the control valve 15a of purified gas outlet, cuts off the filtered airflow of this dedusting tube, makes it off-line, and then the inside and outside differential pressure of filter bag is zero in the tube.At this moment, successively each row's filter bag is carried out jetting deashing by pulse valve 32, branch gas tank 33 and the winding-up pipe 34 pulse jet mechanisms that form.Because the time abundance that coal gas does not flow, control valve is closed so the dust of shaking off can fully be deposited to the ash bucket bottom, has been avoided " dust is attached again " and " deashing inefficacy " phenomenon.Like this, be equipped with on the raw coke oven gas arm on Hand-operated butterfly valve and blank-plate valve, the purified gas arm Pneumatic butterfly valve and blank-plate valve are housed, Pneumatic butterfly valve is as the off-line transfer valve.In the online ash removal mode, still need equip above-mentioned valve, switch, only as the usefulness of off-line maintenance but do not carry out off-line.Raw coke oven gas arm, purified gas arm are equipped with butterfly valve and blank-plate valve, close these valves, can carry out the off-line maintenance to this dedusting tube.If during pulse jetting deashing, do not cut off filtered airflow, this mode is the online ash removal pattern.
Pulse jetting deashing adopts level pressure difference control mode.Control system is made up of differential pressure transmitter, differential pressure controller, program control cabinet and machine side control box etc.The deduster of measuring between famine, the purified gas import and export person in charge with differential pressure transmitter moves drag overall.When it reached the higher limit of setting, robot control system(RCS) was carried out the off-line pulse jetting deashing to each dedusting tube successively; When running resistance dropped to the lower limit of setting, deashing stopped automatically.
The above, it only is specific embodiment of the utility model, when can not limiting the scope that the utility model is implemented with this, i.e. equivalent variations and the modification of doing according to the utility model claim and description generally all should still belong in the scope that the utility model patent contains.
