Description
Technical field
The utility model relates to a kind of dust arrester, particularly a kind of sack cleaner that is used for the alkali recovery furnace dedusting.
Background technology
At present, black liquid is well-known during to the pollution of environment, and in order to solve this environmental issue, the mode by evaporation, burning is processed into black liquor the environment-friendly products that can recycle.Black liquid combusting furnace plays a part very importantly in this technological process, and it is separated the compound of sodium from black liquor, and burning changes into heat and forms steam, has also formed flue gas certainly.Though this technology has solved the water pollution problems, flue gas has caused atmosphere pollution.Include a large amount of corrosive harmful substances in the flue gas, in a single day these harmful substances take down, and are exactly useful commodity.In technology in the past, use electrostatic precipitator to receive the dust that is contained in the flue gas, reached the effect of gathering dust.But find that in use electrostatic precipitator is not bad when just bringing into operation, cathode line is corroded, and the discharging flue dust just surpasses 100mg/Nm3, and the time has been grown to have only as gravity settling chamber and used.
Though in recent years electrostatic precipitator had been done the corresponding techniques renewal, pole plate, polar curve adopt stainless steel, increase electric field quantity, and dust removing effects does not still reach the requirement of 30mg/Nm3 discharge standard.
The utility model content
In order to overcome the deficiency of existing alkali recovery furnace dust removing effects, the utility model provides a kind of sack cleaner that is adapted to the alkali recovery furnace dedusting.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of sack cleaner that is used for the alkali recovery furnace dedusting comprises lower box, upper box, is provided with double-layer rotary access cover plate valve between lower box and the upper box, and upper box top is equipped with blowing device; The both sides of lower box inside are provided with the pouch chamber, and the centre is provided with built-in chimney flue; Be provided with double-deck by-passing valve and secondary deflector between pouch chamber and the built-in chimney flue, the indoor filter bag that is provided with of pouch.
The utility model reclaims the characteristics of black liquid combusting furnace in conjunction with alkali, double-layer rotary access cover plate valve, secondary deflector have been increased, stainless steel is adopted in the pouch chamber, operational factors such as the material of filter bag and filtration velocity have been changed, make this sack cleaner more adapt to the requirement of this operating mode, and can reach the purpose of qualified discharge for a long time.Entire equipment under the control of control system, the automatic operation of the detection signal control appliance by sensor-based system.The bag chamber is a stainless steel, arranges pre-spray equipment, adopts the pouch cell structure, and the pouch chamber is imported and exported and arranged double-layer rotary access cover plate valve; The winding-up of employing off-line, flue is built-in, flue gas utilization secondary diversion technology; Double-deck by-passing valve, self-locking cylinder, dual fail-safe compressed air system and seal fan are set; The filter bag of lower smoke filtration flow velocity, use New Type Material is set, adopts the sensor-based system of pressure, pressure reduction, temperature, turbidity.This equipment has complete frame for movement and sensing, control electro-mechanical system.
The beneficial effects of the utility model are, adopt the pouch cell structure, and flue gas adopts the secondary diversion technology, and good dedusting effect is installed corrosion-resistantly, has the automatic control of pressure, pressure reduction, temperature, turbidity, stable, the high-efficiency environment friendly of dedusting.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, a kind of sack cleaner that is used for the alkali recovery furnace dedusting comprises lower box 4, upper box 9, is provided with double-layer rotary access cover plate valve 3 between lower box 4 and the upper box 9, and upper box 9 tops are equipped with blowing device 11; The both sides of lower box 4 inside are provided with pouch chamber 6, and the centre is provided with built-in chimney flue 2; Be provided with double-deck by-passing valve 5 and secondary deflector 13 between pouch chamber 6 and the built-in chimney flue 2, be provided with filter bag 12 in the pouch chamber 6.
Double-deck by-passing valve 5 is connected with self-locking cylinder 7.
Built-in chimney flue 2 central authorities are provided with built-in by-pass flue 10.
The import of built-in chimney flue 2 is provided with pre-spray equipment 1.
Make for stainless steel pouch chamber 6, and quantity is 4～20.
Equipment is before putting into operation; by pre-spray equipment 1 sprayed protection material filter bag 12 is protected in advance; flue gas by built-in chimney flue 2 under the control of double-layer rotary access cover plate valve 3 through secondary deflector 13 once more water conservancy diversion enter each pouch chamber 6; under the filtration of filter bag 12; flue dust peels off under the effect of blowing device 11, and pure qi (oxygen) enters upper box 9 qualified discharges.
