Abstract
The utility model relates to a combustible gas dry process of belt pressure operation is removed dust and is used sack cleaner. The bag filter is provided with a back-blowing chamber (1), a filter bag (2) and a shell (3), wherein the back-blowing chamber (1) is divided into a left part and a right part, the filter bag (2) is circular, and the shell (3) is a sealed pressure container and can bear higher operation pressure. Is suitable for dry dedusting of chemical devices. The dust remover is divided into two back-blowing chambers, only a valve needs to be opened periodically, inert gas enters the back-blowing chambers to back-blow the cloth bags, and the dust removing efficiency can reach 99%. It is suitable for purifying combustible gas flow, especially for recovering organic matter dust.
Description
The utility model relates to a kind of filtration sack cleaner, especially for a kind of pressure-bearing device of organic matter dust recovery in the fuel gas.
Usually sack cleaner be filter bag (2) be contained in can movable mechanism on, drive by a series of mechanical movement under motor or the gas pressure filter bag up and down or about shake, make the particulate that is adsorbed on the filter bag surface shake off removing, and fall into the interior collection of hopper.Owing to adopt the method for mechanical oscillation deashing, damage filter bag easily, influence the life-span of filter bag, cleaning efficiency is reduced.For containing organic fuel gas, owing to have mechanical widely different commentaries on classics and transmission, be easy to generate spark and cause danger.So can only be used for the dust of incombustible gas reclaims.
The sack cleaner of another kind of type is the pulse bag type dust collector that utilizes the contrary air-flow reverse gas cleaning of compressed air, shakes off dust on the filter bag with air pulse, uses mechanical widely different pivoted arm that air-flow is sent to each filter bag in order usually in order to realize pulse.Perhaps use utility application CN-87204695U to require the intelligent pulse control instrument that uses, carry out air pulse by a series of mechanical movement and distribute.These deduster complex structures, cost height, maintenance difficult.And the shell of these dedusters all can not bear pressure, can only operate under normal pressure or very low pressure, and the scope of application is restricted.
The purpose of this utility model is that a kind of sack cleaner that can bear greater than 0.1MPa pressure simple in structure will be provided, and is specially adapted to the reclaiming clean of organic matter dust in the fuel gas.
The purpose of this utility model is achieved in that
1,3. shell is the pressure vessel of a sealing, and its each pressure parts can bear desired working pressure through internal stress analysis, calculating.
2,4. filter bag below 2. is connected with screen (9) with spring, 3. screen (9) 5. links to each other with shell by limiting plate, screen (9) is a grid type integral body, 5. the amplitude of screen is regulated by limiting plate, as long as have filter bag produce vibrations just can by spring 4. and screen (9) vibrations are passed to each filter bag, thereby realization microseism up and down.
3, about 1. the blowback chamber is divided into two, can make nitrogen pass through nitrogen inlet (10) by by-pass valve control and enter the blowback chamber filter bag is with the pressure blowback.
4,7. air inlet is arranged in tangentially, and the air-flow of band dust enters and promptly produces cyclonic motion in the deduster, and can directly not clash into filter bag.
5, filter bag is 2. rounded, and mid-mounting has undue flattening of cylinder-shaped steel expanded metals (12) restriction filter bag and the injury that may cause.The upper end of filter bag is fixed with clamp (13) and the fixed head in the shell, and it connects reliable.
3. the utility model because only need a bearing shell, have only two blowback chambers 1., and do not need mechanical widely different pivoted arm or intelligent controlling instrument, there is not mechanical transmission device, thereby simple especially its starting point of structure does not lie in how to produce air pulse, and be to form a flexible screen, filter bag can be interacted, about the generation, about microseism.And limiting plate height 5. is adjustable, can regulate its amplitude of vibration and make and be suitable for different requirements.So higher efficiency of dust collection is arranged, and is specially adapted to the recovery of organic matter dust in the fuel gas.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a sketch of the present utility model
2-filter bag 3-shell in 1-blowback chamber among the figure
4-spring 5-limiting plate 6-hopper
7-air inlet 8-visor 9-screen
10-nitrogen inlet 11-gas vent
Fig. 2 is a filter bag cut-away view of the present utility model
12-expanded metal lath 13-clamp among the figure
The gas that contains the polypropylene dust is as shown in Figure 1 entered by the tangential direction of air inlet (7) along deduster, after filter bag (2) filters, air-flow is discharged by gas vent (11), and a dust part is adsorbed on the filter bag surface, another part falls into hopper (6), nitrogen is entered into blowback chamber (1) and is assigned to part filter bag (2) by the nitrogen inlet (10) at top when opening valve, under the gas shock effect, make the filter bag vibrations, and by spring (4) and screen (9) the vibrations biography to all filter bags, realize vibrations up and down, shake off dust.Close the nitrogen valve, recover original situation, air-flow with pressure enters from air inlet (7), makes the filter bag vibrations once more.Garden tubular expanded metal lath (12) in the filter bag (2) is underslung, and it is flat that it had both played the undue suction of restriction filter bag, can utilize the vibration principle of pendulum again, strengthens the effect of microseism.Dust content is preferably in 0.2～0.05kg/m in its gas
3Between, dust size can reach about 99% through using the proof efficiency of dust collection greater than 200 orders.
Claims (4)
1, a kind of fiber bag precipitator, have blowback chamber (1), filter bag (2), shell (3), it is characterized in that blowback chamber (1) be divided into about two, the below of filter bag (2) is connected with screen (9) by spring (4), screen (9) links to each other with shell (3) by limiting plate (5), shell (3) is the pressure vessel of a sealing, and nitrogen inlet (10) and gas vent (11) are arranged in the upper end of shell, and there is gas feed (7) the shell lower end.
2, deduster according to claim 1 is characterized in that screen (9) is grid type integral body, and the amplitude of screen is regulated by limiting plate (5).
3, deduster according to claim 1 is characterized in that filter bag (2) is rounded, and the centre is hung with cylinder-shaped steel expanded metals (12) by clamp (13).
