Outdoor high-temperature smoke gas protective cover

Abstract

The invention discloses an outdoor high-temperature smoke gas protective cover. The outdoor high-temperature smoke gas protective cover comprises a first transition cover and a second transition cover which are distributed symmetrically up and down. An upper cover piece is fixed to the top of the first transition cover. A lower cover piece is fixed to the bottom of the second transition cover. A conical dust sliding hopper is mounted in the first transition cover. An inverted-cone-shaped dust collection hopper is mounted in the second transition cover. A dust exhaust pipe is mounted at the bottom of the dust collection hopper. One end of the dust exhaust pipe communicates with the interior of the dust collection hopper, and the other end of the dust exhaust pipe obliquely penetrates through the lower cover piece downwards to communicate with the outside. Through the lower cover piece, the second transition cover, the first transition cover and the upper cover piece which are sequentially distributed along the axis, the exhaust resistance of high temperature smoke gas can be effectively reduced, and the burnout phenomenon is avoided; and rainwater and dust entering the protective cover can be rapidly drained to the outside, economic losses of equipment where the rainwater and dust flow into are avoided, the influence of direction on exhaust is reduced, and the protective cover is suitable for various regions and has the good using effect and popularization value.

Description

technical field [0001] The invention belongs to the field of protective covers, in particular to an outdoor high-temperature flue gas protective cover. Background technique [0002] During the use of the traditional flue gas shield, due to the high-temperature flue gas being discharged outdoors, it is affected by the rain, and the smoke pipe enters the rainwater or the dust flows back to the equipment, or the exhaust is not smooth due to the influence of the wind direction, and it is common in the market All the fume shields have the disadvantages of large resistance, easy burnout, and easy entry of rainwater and dust, which greatly affects the use effect of the fume shield. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide an outdoor high-temperature flue gas shield, which can quickly discharge high-temperature flue gas and avoid backflow of rainwater and dust. [0004] In order to achi...
