For further explanation of the present invention, the working principle of the present invention is explained as follows:
(1) The waste gas generated in the production is collected by the waste gas collecting cover 1, then reaches the high-pressure fan 3 through the air pipe 2 under the suction action of the high-pressure fan 3, forms a high-pressure air flow under the compression action of the high-pressure fan 3, and is conveyed into the wind-eliminating and emission-reducing mechanism 4;
(2) The high-pressure air flow generated by the high-pressure fan 3 is conveyed into the wind-eliminating and emission-reducing combined pipe 41 in the wind-eliminating and emission-reducing mechanism 4, and is subjected to recompression of the high-pressure spraying pipe 411 in the wind-eliminating and emission-reducing combined pipe 41 to form spraying-shaped high-pressure air and spray the spraying-shaped high-pressure air into the high-pressure sleeve 412, and because a gap of 10mm is kept between the air outlet of the high-pressure spraying pipe 411 and the air inlet of the high-pressure sleeve 412, when the high-pressure air flow in the high-pressure spraying pipe 411 irradiates the high-pressure sleeve 412, a venturi effect of vacuum is generated in a certain area between the air outlet of the high-pressure spraying pipe 411 and the air inlet of the high-pressure sleeve 412, and because of the vacuum state, air flow is needed to be supplemented, and the supplementing air flow is pulled back between the air outlet of the high-pressure sleeve 412 and the air inlet of the high-pressure sleeve 412 through the back pipe 413, and returns to the high-pressure sleeve 412 to form circulating air;
(3) The wind-eliminating and emission-reducing combined pipe 41 can be provided with a primary wind-eliminating and emission-reducing combined pipe, a secondary wind-eliminating and emission-reducing combined pipe, a tertiary wind-eliminating and emission-reducing combined pipe and a multi-stage wind-eliminating and emission-reducing combined pipe according to the requirements, and the air quantity can be reduced by a part through the primary wind-eliminating and emission-reducing combined pipe;
(4) Since the dynamic pressure of the air flow which has been reduced by a considerable amount of air volume after passing through the wind-eliminating and emission-reducing combined pipe 41 is reduced by a great amount, if the air flow directly enters the exhaust pipe 43, the air flow after passing through the wind-eliminating and emission-reducing combined pipe 41 cannot completely overcome the wind resistance of the exhaust pipe 43 due to small dynamic pressure because the cross section area of the normal exhaust pipe 43 is not large and has certain wind resistance, therefore, the rear end of the last wind-eliminating and emission-reducing combined pipe 41 needs to be reserved with a diffusion part 42 with the length of 500mm to achieve the aim of buffering the air flow, and then the air flow is slowly discharged through the exhaust pipe 43, and enters the next waste gas treatment link after passing through the exhaust pipe 43.
The exhaust gas treatment wind-eliminating and emission-reducing device is simple in structure and ingenious in design, high-pressure air flow generated by the high-pressure fan 3 is blown to the high-pressure injection pipe 411 in the wind-eliminating and emission-reducing combined pipe 41, injection-shaped high-pressure air is formed by the high-pressure injection pipe 411 and is injected into the high-pressure sleeve 412, the Venturi effect vacuum principle generated between the air outlet of the high-pressure injection pipe 411 and the air inlet of the high-pressure sleeve 412 when the high-pressure air flow of the high-pressure injection pipe 411 is injected into the high-pressure sleeve 412 is utilized, the air flow of the air outlet of the high-pressure sleeve 412 is pulled back to a part between the air outlet of the high-pressure injection pipe 411 and the air inlet of the high-pressure sleeve 412 through the pull-back pipe 413, so that exhaust gas circulation is formed, and therefore, the effect of reducing air quantity is achieved, a plurality of groups of wind-eliminating and emission-reducing combined pipes 41 can be installed according to requirements, and the air quantity of exhaust gas can be reduced after being treated by a group of wind-eliminating combined pipes 41, the exhaust gas treatment air quantity can be reduced according to actual requirements, the air quantity of the exhaust gas treatment equipment can be reduced, the volume and the exhaust gas treatment equipment can be reduced, the treatment efficiency and the equipment cost and the space and the occupied space cost and the operation cost can be reduced. The exhaust treatment wind-eliminating and emission-reducing device is especially suitable for VOCs exhaust treatment, dust-removing exhaust treatment, boiler exhaust emission treatment, garbage incineration exhaust treatment and the like.
Referring to FIG. 7, FIG. 7 shows a third party detection report during the development of the present invention, and it can be seen from FIG. 7 that under the same test conditions, the standard dry exhaust flow can be significantly reduced after the exhaust gas treatment, wind elimination and emission reduction device is used, and the standard dry exhaust flow is 1.85X10 before the treatment 4 m 3 The/h is reduced to 9.17X10 3 m 3 And/h, the exhaust amount is reduced by 50.43%, the effect of eliminating wind and reducing emission is very ideal, and harmful substances in the exhaust gas, such as: the emissions of particulates, toluene, xylene, VOCs and the like are also significantly reduced.
The foregoing is a preferred embodiment of the present invention, but the present invention should not be limited to the embodiment and the disclosure of the drawings, so that the equivalents and modifications can be made without departing from the spirit of the disclosure.
