By adopting the hollow structure, the utility model reduces the self-weight; and through removing the sparks in the gas, the utility model protects a filter bag in the bag-type dust collector. Therefore, the utility model has the advantages of simple structure, safe operation, reliability, high efficiency, environmental protection and durability.

Description

Spark catcher

1, technical field:

The utility model relates to the high-temperature flue gas controlling device, relates in particular to a kind of device that captures the spark in the high-temperature flue gas.

2, background technology:

China exists the hot stove in a large amount of ore deposits, cement, high temperature manufacturing enterprises such as Industrial Boiler, along with the increasing of China to the management of atmosphere pollution, a large amount of in the past dedusters can not satisfy environmental requirement, for with the dust pollution that reduces these enterprises effectively, generally adopt sack cleaner efficiently now, such deduster can satisfy environmental requirement fully.But because the core component of sack cleaner: the heatproof of filter bag has only below 280 ℃, when the Mars in the flue gas arrives the filter bag surface, will burn filter bag, thereby destroys whole dust-removal system.

3, summary of the invention:

The purpose of this utility model is to propose a kind of simple and reasonable, and the spark catcher that own wt is lighter can be protected the spark catcher of the core component filter bag of sack cleaner effectively.

The purpose of this utility model is achieved in that spark catcher comprises spiral tube, cylindrical drum, aiutage, ash storage box, and the gas-solid separator that is installed in the ash storage box lower port.Aiutage is the uncovered cavity body of upper and lower end, and its upper end is communicated with sack cleaner.Be wrapped with the helical form spiral tube that closes up gradually on aiutage top, both are fixedly connected by connecting plate.Aiutage is enclosed with cylindrical drum by support bar outside the bottom, in cylindrical drum is wrapped in the aiutage lower port.The spiral tube closes up and is communicated with the remainder sealing with a cylindrical drum upper port part.The place is communicated with funnelform ash storage box in the cylindrical drum lower port, and its lower port place is equiped with gas-solid separator.

The utility model is simple in structure, has mainly adopted the design of hollow structure, thereby greatly reduces own wt.By Mars in the gas being rejected the filter bag in the protection sack cleaner.Its work safety, stable, the efficient height, environmental and durable.

4, description of drawings:

Concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is the spark catcher structural representation;

Fig. 2 is a spark catcher plan structure schematic diagram.

Legend: 1, connecting plate, 2, aiutage, 3, support bar, 4, choke dust discharge tube, 5, gas-solid separator, 6, ash storage box, 7, supporting seat, 8, cylindrical drum, 9, the spiral tube, 10, air inlet.

5, the specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment: shown in Fig. 1-2, spark catcher comprises spiral tube 9, cylindrical drum 8, aiutage 2, ash storage box 6, and the gas-solid separator 5 that is installed in ash storage box 6 lower port.Aiutage 2 is the uncovered cavity body of upper and lower end, and its upper end is communicated with sack cleaner.Be wrapped with spiral tube 9 on aiutage 2 tops, spiral tube 9 is the helical form cavity tube that closes up gradually.Aiutage 2 is fixedlyed connected by connecting plate 1 with spiral tube 9.Aiutage is enclosed with cylindrical drum 8 by support bar 3 outside 2 bottoms, in cylindrical drum 8 is wrapped in aiutage 2 lower port.Spiral tube 9 closes up and is communicated with the remainder sealing with cylindrical drum 8 a upper port part.8 lower port places are communicated with funnelform ash storage box 6 in cylindrical drum, and its lower port place is equiped with gas-solid separator 5, and gas-solid separator 5 can be isolated the Mars that captures effectively, simultaneously by the work that does not influence the Mars trap.Top in ash storage box 6 is fixed with one and falls funnelform choke dust discharge tube 4, and it is the cavity body of open at both ends, and its bottom is by support bar 3 and the welding of ash storage box 6 inwalls.8 outer wall places also are provided with supporting seat 7 in cylindrical drum, and it is used for fixing cylindrical drum 8, thus fixing whole spark catcher, and it also can be installed on the framework such as original concrete.

During use, the high temperature dust gas that contains a large amount of Mars enters spiral tube 9 along the air inlet tangential direction of the spiral tube 9 of Mars trap, air-flow will become circular motion by rectilinear motion, owing to be subjected to the restriction of outer ring cylindrical drum 8 cylindrical shells and aiutage 2, force air-flow to do top-down rotatablely moving, air-flow produces bigger centrifugal force in rotary course, spark is under action of centrifugal force, be thrown toward cylindrical drum 8 inwalls gradually, the spark that touches inwall loses inertia and in the effect lower edge of gravity inwall whereabouts, enters ash storage box 6 bottoms by choke dust discharge tube 4 and 6 of ash storage boxs.The outer rotational gas flow that rotation descends compiles to ash storage box 6 bottom centre because of being subjected to conical influence of shrinking when arriving ash storage box 6.According to " spin moment " invariance principle, its tangential velocity improves constantly.When air-flow drops to a certain degree, begin to return rising, form one rotatablely moving from bottom to top, promptly in rotational gas flow.Interior rotational gas flow does not contain big dust particle, and promptly spark discharges through choke dust discharge tube 4, cylindrical drum 8, aiutage 2.Because choke dust discharge tube 4 is isolated into and out of two kinds of swirling eddies, can prevent effectively that the spark that is sunken to ash storage box 6 bottoms is taken up.

Suppose need to handle contain the spark High Temperature Gas scale of construction be the Q cubic meter/hour, by aiutage 2, then can calculate aiutage 2 diameters is d with speed of 16-18m/s for it, then aiutage 2 length preferred 〉=2d; Cylindrical drum 8 diameters are preferred 〉=2d, highly preferred 〉=3d; Ash storage box 6 upper end diameter are preferred 〉=2d, highly preferred 〉=2.5d.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
