Summary of the invention
The purpose of this utility model is at not enough defective of the prior art, provides that a kind of structure is simpler, compacter, the spraying and blowing organ of the flue gas processing device that is easier to safeguard.
For achieving the above object, the utility model adopts a kind of spraying and blowing organ of flue gas processing device, comprise pulse valve, blowing pipe, air accumulator, on the air accumulator, following two ends form opening, pulse valve adopts the submerged pulse valve, the submerged pulse valve is arranged on upper shed place of air accumulator and constitutes static seal, the upper gas chamber of submerged pulse valve and air accumulator internal communication, the discharge chamber lower end of submerged pulse valve connects a straight tube, this straight tube vertically is arranged in the air accumulator, and the lower end of straight tube is connected with the under shed of air accumulator and constitutes static seal, and blowing pipe adopts bend pipe, bend pipe one end is connected with the straight tube lower end, and other end front end forms adpting flange.
In order to guarantee that straight tube is connected with bend pipe reliably, this practicality further is set to the straight tube lower end and the bend pipe junction forms the endoporus step, and bend pipe inserts in the straight tube and with this endoporus step and constitutes close-fitting.
In order to guarantee good airproof performance between straight tube and the bend pipe, the lower end that this practicality further is set to the corresponding straight tube of lower opening of air accumulator forms lower flange, be provided with the end cap corresponding in bend pipe one side with lower flange, lower flange and this end cap are bolted to connection, between lower flange and straight tube, directly be provided with sealing ring and constitute static seal, between end cap and straight tube, be provided with airtight and watertight padding and constitute static seal.
In order to guarantee that the submerged pulse valve is connected with air accumulator reliably, this practicality further is set to form upper flange in upper shed place of air accumulator again, and the submerged pulse valve is fixedlyed connected with air accumulator by flange.
The utility model has carried out following several improvement: 1, blowing pipe adopts bend pipe, has reduced the scouring intensity of high-speed gas, the life-span of having improved each parts;
2, the gas tube wall of flowing through adopts stainless steel, has improved the corrosion resistance of parts;
3, adopted rational thread connection, maintain and replace is quick;
4, the MD262S right-angle impulse valve with prior art changes SYKL89 submerged pulse valve into, has reduced the scouring intensity of high-speed gas to valve body.
Advantage after the improvement:
1, service life of equipment has improved two to three times;
2, consumable accessory by original pulse valve, round nut, flush the pipe three become one of bend pipe, saved maintenance cost greatly;
When 3, keeping in repair, the speed of renewal part has improved two to three times.
