[0041] In order to solve the problem that the exhaust gas cannot be properly purified after being extracted, the present invention provides a dust removal and exhaust device for industrial plants and a method for using the same. The following is a further description of the dust removal and exhaust device for industrial plants and a method for using the same with specific embodiments and drawings.

[0042] See also Figure 1 to Figure 4 As shown, a dust removal and exhaust device for industrial plants comprises:

[0043] Support 2;

[0044] The purification box 4 is fixed to the top of one end of the support 2, and the interior of the purification box 4 is filled with a solution for removing dust from the exhaust gas inside the purification box 4;

[0046] The exhaust device is fixed to the top of the other end of the support 2 and is used to extract the waste gas in the industrial plant 1 and transport it to the purification box 4;

[0047] A plurality of limit plates 11 submerged in the solution are arranged at intervals along the height direction of the purification box 4 to divide the interior of the purification box 4 into a plurality of purification spaces 13 for exhaust gas dust removal; each limit plate 11 is provided with a vent 111 to allow exhaust gas to flow through a purification space 13 to an adjacent purification space 13; the positions of the vents 111 on the plurality of limit plates 11 are staggered to extend the flow time of exhaust gas from a purification space 13 to an adjacent purification space 13 through the vent 111; and

[0048] The guide pipe 8 passes through several limit plates 11 and is used to guide the exhaust gas transported to the inside of the purification box 4 to the lowest purification space 13; the exhaust gas after dust removal in the lowest purification space 13 enters the adjacent purification space 13 through the vent 111 to achieve layer-by-layer dust removal of the exhaust gas.

[0049] Specifically, in this embodiment, the solution may be water; see Figure 3 As shown, when the waste gas is extracted from the industrial plant 1 and transported to the purification box 4, the transported waste gas will be guided to the lowest purification space 13 through the guide pipe 8, the waste gas and water are dissolved and purified, and then enter the adjacent purification space 13 through the vent 111, thereby realizing the layer-by-layer dust removal and purification of the waste gas, and the purified gas can be discharged through the air outlet 10 at the top of the purification box 4; by staggering the positions of the vents 111 on the plurality of limit plates 11, the waste gas can flow to the end where the vent 111 is opened after being purified in a purification space 13, which greatly prolongs the flow time of the waste gas from a purification space 13 to an adjacent purification space 13 through the vent 111, thereby increasing the contact time between the waste gas and water, thereby fully dissolving and purifying, and further improving the waste gas purification effect; a drainage pipe for discharging waste water is provided on the purification box 4.

[0050] Among them, see Figure 1 As shown, the exhaust device includes an exhaust fan 3 fixed to the top of the support 2, an air inlet pipe 6 and an air delivery pipe 7;

[0052] One end of the air delivery pipe 7 is connected to the exhaust fan 3, and the other end is connected to the top of the purification box 4, so as to deliver the extracted exhaust gas into the purification box 4;

The plurality of air intake pipes 604 are respectively opened on the plurality of ventilation pipes 603, and the plurality of air intake pipes 604 in each group of air intake pipes 604 are equidistantly arranged on the corresponding ventilation pipes 603.

[0054] By providing the annular pipe 602, a plurality of suction pipes 604 and a plurality of ventilation pipes 603, the waste gas can be sucked out from the industrial plant 1 more quickly for purification and discharge, thereby improving the efficiency of waste gas purification.

[0055] Among them, see Figure 2 As shown, a connecting port for inserting the gas pipe 7 is penetrated through the top of the purification box 4, and a sealing sleeve 9 is provided at the connection between the connecting port and the gas pipe 7.

[0056] The connecting area between the gas delivery pipe 7 and the purification box 4 is sealed by the sealing sleeve 9 to prevent leakage of the transported waste gas.

[0057] Among them, see Figure 3 As shown, the flow guide pipe 8 includes a main pipe body 801, a secondary pipe body 802 and a plurality of gas outlet nozzles 803;

[0058] One end of the main body 801 is rotatably connected to the bottom of the sealing sleeve 9 and communicates with the gas delivery pipe 7;

[0061] The secondary tube 802 is offset from the vent 111 on the lowermost limiting plate 11 .

[0062] By connecting the sealing sleeve 9 to the connection between the main body 801 and the air supply pipe 7, a sealing effect can be achieved to prevent leakage of exhaust gas; by setting the secondary tube body 802 in the outer area within the lowest purification space 13 and staggering the position of the exhaust nozzle 803 and the vent 111 located on the lowest limiting plate 11, the time for the exhaust gas output through the exhaust nozzle 803 to flow to the vent 111 can be extended, so as to increase the sufficient contact time between the exhaust gas and water, thereby achieving a better purification effect.

[0066] Specifically, the driving rod is driven to rotate by starting the motor 12, and then the main pipe body 801 and the secondary pipe body 802 are used to drive the plurality of gas outlet nozzles 803 to rotate, so that the position of the gas outlet nozzles 803 is changed, thereby increasing the contact area between the exhaust gas and the solution and improving the efficiency of the dissolution purification; further, the overall structure of the limiting plate 11 is uneven and may be corrugated. When the main pipe body 801 rotates, it will drive the plurality of limiting plates 11 to rotate. The uneven limiting plates 11 can be used to stir the water and exhaust gas inside the purification box 4, so that they can be in more complete contact, thereby further improving the exhaust gas purification effect.

[0067] Among them, see Figure 3 As shown, a circulation device is fixedly installed on the top of the support 2, which is used to extract part of the solution and waste gas in the purification space 13 located at the top in the purification box 4 and introduce them into the purification space 13 located at the bottom;
