Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of portable smoke capture dust removal device in flue gas dust removal technical field. BACKGROUND

[0002] In the process of casting molten iron, slagging, raking and casting, the high-temperature molten silicon-manganese alloy will contact with air to produce a large amount of harmful smoke with long duration time. The smoke contains harmful solid particles such as metal dust. The equipment in the casting workshop is usually placed with an open mouth, which causes the smoke to be released or dissipated in the workshop environment, seriously polluting the working environment of the workshop and greatly endangering the health of the operating personnel. The smoke is also likely to spread outside the casting workshop, making the unorganized particulate matter emission outside the casting workshop exceed the standard and failing to meet the environmental protection requirements. Therefore, in the face of increasingly stringent environmental protection requirements, production enterprises must capture and collect the smoke for dust removal treatment.

[0003] In the prior art, the smoke capture dust removal device is mostly provided with a dust collection hood of a certain area at the dust source point to collect the smoke dust generated by the dust source. The captured smoke enters the dust collector through a pipeline under the negative pressure of the dust removal system fan for dust removal and is finally discharged into the atmosphere. The dust collection hood is mainly divided into two categories, i.e., a fixed hood and a mobile hood. The fixed hood means that the hood is fixed and does not move to capture the smoke of the fixed dust source. Since there are many devices in the dust removal area at times, especially the overhead crane in the workshop, the fixed hood is likely to interfere with the overhead crane and other devices, so that the application range of the fixed hood is limited. The mobile hood means that the hood moves under the action of a driving device. The hood moves to the working position during work and moves away after work. The currently widely used mobile hood is a track-type mobile hood that moves horizontally.

[0004] However, the track-type mobile hood moves by relying on the guide rail and must keep the guide rail unobstructed. It can only move in the direction of the installed guide rail, which results in low moving efficiency and affects the dust removal efficiency. UTILITY MODEL CONTENT

[0005] The utility model aims to provide a portable smoke capture dust removal device to solve the problem that the track-type mobile hood in the prior art moves by relying on the guide rail and must keep the guide rail unobstructed.
