Abstract
The utility model relates to an annular impulse gas enclosure, belonging to the technical field of environmental protection device, essentially comprising a flange, a vertical pipe, an upper panel, a lower panel, a steel pipe, an impulse valve flange, an escaping pipe, a spray-pipe flange and the like, characterized in that the annular impulse gas enclosure rotates about the same axes as the center of the dust catcher body, a center of an air feeding point is coaxial with an air receiving point, and the soot cleaning apparatus of annular impulse gas enclosure promotes the spraying function of the impulse valve and at the same time the installation is simplified. Compared with a rectangle gas enclosure and a cylinder gas enclosure, the weight and number of the are largely decreased soot cleaning apparatus of the gas enclosure, the impulse valve and the like, thereby reducing the cost of the dust catcher equipment, having the advantages of good soot cleaning effect, low resistance, steady operation, and easy mounting.
Description
Technical field
The utility model relates to a kind of loop pulse gas bag, is applicable to the storage device of sack-duster pulse deashing source of the gas, belongs to environmental technology field.
Background technology
At present, the gas bag of conventional pulse bag-type dust-removing is made up of cylindrical shell, last lower flange, air inlet pipe, winding-up pipe blow-off pipe, and the gas bag profile is rectangle or cylindrical shape.Usually all install by tens of groups of fixing gas bag deashing devices on every deduster.Every group of gas bag soot cleaning system is made up of several pulse valves of installation, winding-up pipe, flange.During its work, every group of soot cleaning system fixed corresponding one group of filter bag, realizes the pulse dust cleaning of this group, and corresponding every group of filter bag is divided into a fixing locellus that has the off-line valve again, makes it to form off-line state, and the two is in conjunction with realizing the off-line pulse dust cleaning.Its shortcoming is that the structure of devices such as gas bag, pulse valve, off-line valve, winding-up pipe is numerous and diverse and quantity is a lot, and ash-removal effect is poor, causes the dust remover resistance height, many deficiencies such as construction costs and operating cost height.
Technology contents
The purpose of this utility model is to provide a kind of 3 pulse valves of realizing simple, that structure is extremely simple just can finish the deashing of whole filter bags; Ash-removal effect is good; Can reduce the resistance of deduster and decrease, reduce the loop pulse gas bag of operation power consumption.
The technical solution of the utility model is design like this:
In order to be implemented in the off-line pulse dust cleaning under the gyration state, cancellation is by a plurality of fixing chamber off-line devices of only isolating one group of filter bag, cancellation is with the gas bag deashing device of numerous fixing only corresponding one group of filter bag, design one recover transhipment moving, can finish whole filter bags are realized the feeder of off-line pulse dust cleaning in turn, structure is very simple and reliable, reasonable, practical purpose thereby reach.
A kind of loop pulse gas bag that is used for pulse dust cleaning, it mainly is made up of top panel, lower panel, steel pipe, flange, straight tube, pulse valve flange etc., mainly adopts top panel, lower panel and steel pipe to be welded into airtight annular; Flange and the fixing back of straight tube welding are welded to form inlet duct with top panel; The pulse valve flange is fixed in the above above the plate, and air-out apparatus is formed in escape pipe and flange welding back and lower panel welding.Being characterized in profile ringwise, is cavity in it; Be characterized in and the coaxial rotation in deduster body center, air feed dot center be bullied a little coaxial.
The utility model technical parameter:
Loop pulse gas bag operating pressure 0.4～0.6Mpa
Pulse source of the gas operating pressure 0.45Mpa
Pressure-relief valve pressure 0.6Mpa
Compared with the prior art the utility model has the following advantages:
1. owing to adopt loop pulse gas bag with the coaxial rotation in deduster body center, each pulse valve is finished the deashing to some groups of cloth bags respectively, thereby realizes that 3～6 pulse valves finish the deashing of whole filter bags.
2. because the loop pulse gas bag is concentric with the body centre of gyration, air feed dot center and the innovative design structure of being bullied a little coaxial, compressed air directly enter to jet in moment and manage, it is big to have capacity, lower resistance and Geng Gao winding-up flow velocity, bleed pressure can reach about 0.3Mpa, and ash-removal effect is good.
3. because loop pulse gas bag deashing device at the jetting performance that improves pulse valve simultaneously, is simplified installation again.Compare with rectangle gas bag, cylinder gas bag, deashing device weight such as gas bag, pulse valve and quantity are significantly reduced, reduce the deduster equipment manufacturing cost, have the advantage that ash-removal effect is good, resistance is low, operate steadily.And easily install.

Fig. 4 is the utility model structure I enlarged drawing.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by 1, flange 2, straight tube 3, top panel 4, lower panel 5, steel pipe 6, pulse valve flange 7 winding-up flanges, 8 escape pipes etc. form.
The utility model mainly adopts top panel (3), lower panel (4) to be welded into airtight annular with steel pipe (5); Straight tube (2) is weldingly fixed on the top panel (3) with flange (1), forms inlet duct; The pulse valve flange is fixed in the above on the plate (3), and escape pipe (8) one ends are communicated with pulse valve flange (6), and air-out apparatus is formed in the other end and lower panel (4) winding-up pipe flange (7) welding.
During use, discharge pipe is installed at body drum center, slew gear is equipped with on discharge pipe top, on slew gear top the loop pulse gas bag is housed, pulse jet mechanism is arranged on the loop pulse gas bag, the off-line cover is housed in the pulse jet mechanism, the air supply pipe of winding-up caisson is housed at body drum center.The loop pulse gas bag is in gyration, Compressed Gas at first enters the prime reception gas bag concentric with air supply pipe by dynamic sealing device, again by the flexible loop pulse gas bag of delivering to communicating pipe, the loop pulse gas bag not only provides the Compressed Gas source of the gas of pulse jet, and in gyration, drive the winding-up pipe and stably do gyration, and filter bag is finished all pulse jetting deashing in turn.
Operation principle
The pulse source of the gas is heated to 40～60 ℃ through the heating gas bag with compressed air.When filter bag absorption dust acquires a certain degree, when resistance of the filter bag increases, be contained in the pulse valve energising on the loop pulse gas bag, connect compressed air line, compressed air is sprayed to the nozzle on the pipe of jetting through pulse valve, bend pipe by the loop pulse gas bag, and the temporary impact air-flow of its generation is removed the dust on the filter bag.Pulse valve conduction time is 0.1s.
