Abstract
The utility model discloses an automatic dust-falling environment-friendly exhaust device, which comprises: the gas collecting hood is arranged at the upper part of the operation area; the bottom inlet end of the dust-reducing box is correspondingly connected with the top outlet end of the gas-collecting hood; the exhaust pipe is arranged at the outlet end of the dust reducing box; the umbrella cap is arranged on the top outlet of the exhaust pipe; and the vibrator is arranged on the side wall of the dust fall box.
Description
Technical Field
The utility model relates to the technical field of dust-containing waste gas or dust-containing steam exhaust devices, in particular to an automatic dust-settling environment-friendly exhaust device.
Background
In industrial production, in order to improve the concentration of dust, steam and dust-containing gas in the working environment, exhaust gas is generally discharged outwards by adopting a mode of additionally arranging an exhaust pipe, and the dust contained in the exhaust gas can pollute the atmosphere. Along with the increasing environmental protection requirements, direct discharge of dust with high concentration is not allowed; each enterprise invests a large amount of funds into environmental protection facilities to carry out dust treatment. However, dust containing steam or cohesive materials can adhere and harden on the dust removing facilities, damage the dust removing facilities, reduce dust removing efficiency, and have high equipment purchase and maintenance cost.
Disclosure of Invention
Aiming at the technical problems, the utility model provides an automatic dust-settling environment-friendly exhaust device.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
an automatic dust fall environmental protection exhaust apparatus, comprising:
the gas collecting hood is arranged at the upper part of the operation area;
the bottom inlet end of the dust-reducing box is correspondingly connected with the top outlet end of the gas-collecting hood;
the exhaust pipe is arranged at the outlet end of the dust reducing box;
the umbrella cap is arranged on the top outlet of the exhaust pipe;
and the vibrator is arranged on the side wall of the dust fall box.
The dust box and the outer wall of the exhaust pipe are made of fiber glass reinforced plastic or rolled steel plates.
The diameter of the dust settling tank is more than 2 times of that of the exhaust pipe.
The beneficial effects of the utility model are as follows: the utility model is erected above a dust-producing point, waste gas containing dust is pumped in by utilizing the pressure difference between the inlet and the outlet of the exhaust pipe, when the waste gas containing dust flows through the dust-reducing box, the flow speed of the waste gas is reduced, dust particles in the waste gas are settled under the action of gravity, dust in the dust-containing waste gas is separated from the waste gas, and the waste gas is discharged through the exhaust port in an environment-friendly way. The utility model has low cost, simple structure and good dust removal effect. The utility model has reliable performance and can effectively prevent the capability reduction of the exhaust pipe caused by the adhesive material on the inner wall of the exhaust pipe. The utility model is especially suitable for exhaust gas discharge with high dust viscosity or a large amount of dust-containing steam.

Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
As shown in fig. 1, an automatic dust-settling environmental-protection exhaust apparatus includes: the gas collecting hood 4 is arranged at the upper part of the operation area; the bottom inlet end of the dust box 3 is correspondingly connected with the top outlet end of the gas-collecting hood 4; the exhaust pipe 2 is arranged at the outlet end of the dust fall box 3; an umbrella cap 1 arranged on the top outlet of the exhaust pipe 2; vibrator 5 sets up on dust fall case 3 lateral wall, and dust fall case 3 and blast pipe 2 outer wall material are fiber glass steel or roll up the steel sheet, and dust fall case 3 diameter is more than 2 times of blast pipe 2 diameter.
When the dust-collecting hood is used, the gas-collecting hood 4 is arranged above a dust-producing point, waste gas containing dust is pumped in by means of pressure difference between the inlet and the outlet of the exhaust pipe 2, when the waste gas containing dust passes through the dust-reducing box 3, the flow speed of the waste gas is reduced, dust particles in the waste gas are settled under the action of gravity, dust in the dust-containing waste gas is separated from the waste gas, the waste gas is discharged in an environment-friendly way through the exhaust pipe 2, and the vibrator 5 is arranged on the body of the dust-reducing box 3 to periodically vibrate and clean the adhesive and accumulated dust in the dust-collecting hood, so that the effective volume effect of each part in the exhaust pipe is better.
The dust settling effect of the utility model depends on the ratio of the diameter of the dust settling tank 3 to the diameter of the exhaust pipe 2 and the volume of the dust settling tank 3; the larger the diameter ratio of the dust reducing box 3 to the exhaust pipe 2 is, the better the dust reducing effect is; the larger the volume of the dust box 3 is, the better the dust reducing effect is, and meanwhile, the exhaust amount of the utility model depends on the height of the exhaust pipe 2 and the difference between dust-containing waste gas and the ambient temperature; the higher the exhaust pipe 2 is, the larger the exhaust amount is; the larger the difference between the temperature of the dust-containing waste gas and the outdoor environment temperature is, the larger the exhaust gas quantity is, the smaller the distance between the gas collecting hood 4 and the dust generating point is, the better the sealing around the dust collecting hood is, and the better the dust removing effect is.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
