Abstract
The smoke collection dust falling cover comprises a cover body, a smoke collection chamber arranged in the cover body, a smoke outlet arranged on the top surface of the cover body, a smoke inlet arranged on the bottom surface of the cover body, a tapered structure with a narrow upper part and a wide lower part, and an annular partition plate arranged on the inner wall of the smoke collection chamber, wherein the annular partition plate separates the smoke collection chamber into an upper smoke collection chamber and a lower smoke collection chamber, a flap valve is arranged in the center hole of the annular partition plate, a desulfurization gas outlet communicated with the upper smoke collection chamber and a desulfurization gas inlet communicated with the lower smoke collection chamber are arranged on the side wall of the cover body, and the desulfurization gas outlet is tangent to the upper smoke collection chamber. The device has simple structure and low cost, and can remove the smoke dust particles and sulfur-containing gas discharged by the roasting furnace and avoid polluting the atmosphere.
Description
Technical Field
The utility model relates to a calcination production is with collection petticoat pipe, especially relates to a collection cigarette falls dirt cover.
Background
In the roasting production, a large amount of flue gas is discharged from the roasting furnace, and the discharged flue gas contains smoke dust particles and sulfur-containing gas, so that the atmosphere is polluted. At present, the flue gas discharged from the roasting furnace is mainly treated by water mist for dust removal, the water mist dust removal equipment has a complex structure and high manufacturing cost, and the water mist dust removal can only remove smoke dust particles, so that sulfur-containing gas cannot be removed, and the flue gas treatment is not thorough.
Disclosure of Invention
The utility model provides a solve above-mentioned technical problem, provide a collection cigarette dust fall cover, its simple structure, the cost is low, can get rid of the smoke and dust granule that the burning furnace discharged with contain sour gas over a slow fire, avoids polluting the atmosphere.
The technical solution of the utility model is that:
dust hood falls in collection cigarette, including the cover body, locate the internal collection smoke chamber of cover, locate the exhaust port of cover body top surface, locate the inlet flue of cover body bottom surface, its special character lies in: the smoke collecting chamber is of a conical structure with a narrow upper part and a wide lower part, an annular partition plate is arranged on the inner wall of the smoke collecting chamber and divides the smoke collecting chamber into an upper smoke collecting chamber and a lower smoke collecting chamber, a flap valve is arranged in the center hole of the annular partition plate, a desulfurization gas outlet communicated with the upper smoke collecting chamber and a desulfurization gas inlet communicated with the lower smoke collecting chamber are arranged on the side wall of the cover body, and the desulfurization gas outlet is tangent to the upper smoke collecting chamber.
Further preferably, the inner edge of the annular baffle plate inclines downwards, and the dust settling effect of the lower smoke collecting chamber is improved.
Preferably, a motor for driving the flap valve to turn up and down is arranged on the side wall of the cover body.
Further preferably, the bottom of the side wall of the cover body is provided with an ash cleaning opening.
The utility model has the advantages that:
1. because the conical lower dust collecting chamber removes dust of large-particle smoke dust discharged by the roasting furnace by gravity, because the desulfurizing air outlet which is arranged on the side wall of the cover body and communicated with the upper smoke collecting chamber and the desulfurizing air inlet which is communicated with the lower smoke collecting chamber are respectively connected with the desulfurizing air inlet and the desulfurizing air outlet through pipelines, sulfur-containing gas discharged by the roasting furnace is desulfurized, because the conical upper dust collecting chamber removes dust of small-particle smoke dust discharged by the roasting furnace by rotational flow, and finally the smoke discharged by the roasting furnace is removed dust and desulfurized, the mechanism structure is simple, and the manufacturing cost is low.
2. The flap valve arranged in the central hole of the annular partition plate can discharge the small particle smoke settled in the upper smoke collection chamber to the bottom of the lower smoke collection chamber at regular intervals, thereby being convenient for recovery.

Detailed Description
As shown in fig. 1 and 2, the smoke-collecting dust-falling cover comprises a cover body 1, a smoke-collecting chamber arranged in the cover body 1, a smoke outlet 2 arranged on the top surface of the cover body 1, a smoke inlet 3 arranged on the bottom surface of the cover body 1, and a dust removing opening 4 arranged at the bottom of the side wall of the cover body 1, wherein the smoke-collecting chamber is of a tapered structure with a narrow top and a wide bottom, an annular partition plate 5 is arranged on the inner wall of the smoke-collecting chamber, the smoke-collecting chamber is divided into an upper smoke-collecting chamber 6 and a lower smoke-collecting chamber 7 by the annular partition plate 5, the inner edge of the annular partition plate 5 is inclined downwards, a flap valve 8 is arranged in the center hole of the annular partition plate 5, a motor 11 for driving the flap valve 8 to turn over upwards and downwards is arranged on the side wall of the cover body 1, and a desulfurization gas outlet 9 communicated with the upper smoke-collecting chamber 6 and.
During installation, the cover body 1 is arranged above the roasting furnace, and the desulfurization air inlet 10 and the desulfurization air outlet 9 are respectively connected to a desulfurization system through pipelines. Flue gas that the burning furnace produced gets into lower smoke-collecting chamber 7, large granule smoke and dust descend to lower smoke-collecting chamber 7 bottom under the 7 toper inner walls effects of lower smoke-collecting chamber, carry out preliminary gravity and subside, flue gas after preliminary gravity subsides gets into desulfurization system through desulfurization air inlet 10, the flue gas desulfurization after will preliminary subside, flue gas after the desulfurization gets into upper smoke-collecting chamber 6 through desulfurization gas outlet 9, the little granule smoke and dust after the desulfurization sinks to annular baffle 5 on at 6 toper inner walls effects of upper smoke-collecting chamber whirls, make through exhaust port 2 exhaust flue gas tail gas pollution-free.
The above description is only an example of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
