After the dust-containing flue gas enters the filter bag chamber through the air inlet pipe, dust is blocked outside the filter bag when the dust-containing flue gas passes through the filter bag, and purified air flows upwards in the filter bag, enters the air purifying chamber and is discharged through the exhaust pipe. When the high-temperature electric furnace flue gas is purified, in order to avoid the flue gas from burning to damage the filter bag, the flue gas is generally required to be cooled.

The Chinese patent application with publication number CN106362533A discloses a time-delay pressurizing bag-type dust collector, which comprises a dust collector body consisting of an air inlet pipe, an air outlet pipe and a liquid discharge pipe, wherein a spiral pipe is arranged in a bucket area, a fixed rod is vertically arranged in the bucket area, and a spring is sleeved outside the fixed rod; the top of the spring is fixedly connected with a cover plate, and a hollow circular plate is arranged at the top of the bucket area and positioned in the dust remover body; the lower partition plate and the upper partition plate are communicated through a communicating pipe, a buffer area is arranged on the communicating pipe, a cloth bag assembly is arranged above the upper partition plate in the dust remover body, a bag is arranged on the cloth bag assembly, and a pulse pipe is arranged in the cloth bag assembly. The bag-type dust collector effectively cools the flue gas by prolonging the retention time of the flue gas at the bottom in the dust collector, and prolongs the service life of the bag.

Preferably, the water inlet is arranged on the bottom surface of the water tank, and the water outlet is higher than the water inlet. After adopting above-mentioned technical scheme, the water of pouring into piles up from the water tank bottom to the casing absorbs the flue gas heat as the medium, and the water injection lasts and goes on, makes the water after the heat absorption rise, flows from the outlet, and takes away the heat.

Preferably, the water outlet is higher than the sealing ring and lower than the flower plate. After the height of the water outlet is limited, the highest water level in the water tank is lower than the flower plate and higher than the sealing ring, so that on one hand, the filter bag is prevented from being damped and blocked after water enters the heat conducting cylinder, on the other hand, the water is in contact with the heat conducting cylinder to conduct heat after the water level is lower than the sealing ring, and the temperature of the heat conducting cylinder is accelerated to be reduced.

Preferably, the top surface of casing is provided with the closed-loop groove, the notch of closed-loop groove is upwards, the inner circle of closed-loop groove is the heat conduction section of thick bamboo. After the technical scheme is adopted, a certain amount of water is contained through the closed-loop groove, so that the water is in contact with the heat conducting cylinder, and the heat radiation and cooling of the heat conducting cylinder are accelerated.

Preferably, the outer surface of the heat conduction cylinder is provided with a concave part, and the concave part is positioned above the sealing ring.

As shown in fig. 1, the improved electric furnace bag-type dust collector of embodiment 1 comprises a shell 1, an air inlet pipe 2, a flower plate 3 and a plurality of filter bags 4, wherein the bottom end of the shell 1 is provided with an ash discharge port, and the shell 1 is formed by connecting an upper cylinder part and a lower cone part; the top surface of the shell 1 comprises a heat conduction cylinder 5 and a sealing ring 6, the heat conduction cylinder 5 is connected with the pattern plate 3, the heat conduction cylinder 5 is connected with the shell 1 through the sealing ring 6, and the filter bag 4 is arranged in the heat conduction cylinder 5; the electric furnace bag-type dust collector further comprises a water tank 7 arranged on the periphery of the shell 1, the bottom surface of the water tank 7 is arranged above the dust discharging port, a water inlet 8 and a water outlet 9 are arranged on the water tank 7, and the air inlet end of the air inlet pipe 2 is positioned outside the water tank 7. The top surface of the shell 1 is provided with a closed-loop groove, the notch of the closed-loop groove faces upwards, and the inner ring of the closed-loop groove is a heat-conducting cylinder 5.

Before the electric furnace bag-type dust collector operates, water is injected into the water tank 7 through the water inlet 8, and water is discharged from the water outlet 9, so that the water in the water tank 7 flows; then in dusty electric stove flue gas passes through intake pipe 2 entering casing 1, along the inner wall spiral downward flow to the bottom of casing 1, later upward flow gets into heat conduction section of thick bamboo 7, detains the smoke and dust through filter bag 3, and the air after the purification passes through the blast pipe discharge of card 3 top, realizes the purification of dusty electric stove flue gas.

When the flue gas flows in the casing 1, the water in the water tank 7 uses the casing 1 as a medium, and exchanges heat with the flue gas, so that the flue gas is prevented from being damped to block the filter bag 4 while the temperature is reduced, and the dust removal efficiency of the equipment is reduced.

When the smoke flows downwards spirally, the flow path is prolonged, the heat transferred to the shell 1 by the smoke is increased, the temperature is reduced, dust particles in the smoke are trapped on the inner wall of the shell 1 under the action of centrifugal force through spiral motion, the dust particles slide down along the inner wall of the shell 1 and are discharged from the dust discharge port, and therefore the dust amount blocked by the filter bag 4 in unit time is reduced, and the period of the filter bag 4 reaching dust load is prolonged; when the flue gas upward flow, heat conduction section of thick bamboo 5 absorbs the flue gas heat through its inner wall and flue gas contact to give off the heat to the outside, compare in prior art, increased heat radiating area through heat conduction section of thick bamboo 5, thereby strengthen the cooling.

By adopting the design, water injected into the water tank 7 is accumulated upwards from the bottom and is contacted with the shell 1, then the shell 1 is used as a medium to exchange heat with the flue gas, and the temperature of the flue gas is increased while the temperature of the flue gas is reduced; as the water inlet 8 is continuously filled with water, the water level rises, and the water after temperature rise is discharged from the water outlet 9 while taking away the absorbed heat.

The water outlet 9 is higher than the sealing ring 6 and lower than the flower plate 3. After the water outlet 9 is limited in height, in the process of injecting water into the water tank 7, the water level in the water tank 7 is lower than the flower plate 3, so that the filter bag 4 is prevented from being affected with damp when water enters the heat conduction cylinder 5; the water outlet 9 is higher than the sealing ring 6, so that water in the water tank 7 is in contact with the heat conducting cylinder 5 to conduct heat after being higher than the sealing ring 6, and therefore cooling of the heat conducting cylinder 5 is accelerated, and the heat of smoke inside the heat conducting cylinder 5 is absorbed favorably.
