[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] A Venturi spray pretreatment device of the present utility model sprays water atomized from the bottom of the spray assembly to spray and treat the waste gas. The sprayed water accumulates at the bottom inside the tower body. Since the height of the water outlet pipe is higher than the height of the air inlet of the waste gas pipe, the water will accumulate to a certain depth at the bottom inside the tower body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-6 The utility model provides a venturi spray pretreatment device, comprising: a tower body 1, and also comprising: a net box 2 fixed to the inner wall of the tower body 1, an activated carbon adsorbent 3 is placed in the net box 2, and a spray assembly 4 is rotatably installed on the net box 2, a water supply pipe 5 is installed on the outer wall of the top of the tower body 1, and the bottom end of the water supply pipe 5 is rotatably connected to the inner wall of the top of the spray assembly 4, a guide assembly 6 is fixed to the inner wall of the tower body 1, and a stirring assembly 7 is fixed to the bottom of the spray assembly 4, a motor 8 is installed on the outer wall of one side of the tower body 1, and a transmission assembly 9 is installed on the output shaft of the motor 8, the motor 8 is transmission-connected to the spray assembly 4 through the transmission assembly 9, and an exhaust pipe 10 is connected to the inner wall of one side of the tower body 1, a one-way valve 11 is installed on the exhaust pipe 10, and a water outlet pipe 12 is connected to the inner wall of the other side of the tower body 1, and a venturi pipe 501 is installed on the water supply pipe 5.

[0021] It should be noted here that: the exhaust gas can be passed into the tower body 1 through the exhaust pipe 10, and water can be supplied to the spray assembly 4 through the water supply pipe 5. The water is sprayed out from the bottom of the spray assembly 4 in atomized form to spray the exhaust gas. The sprayed water accumulates at the bottom of the tower body 1. Since the height of the water outlet pipe 12 is higher than the height of the air inlet of the exhaust pipe 10, the water will accumulate to a certain depth at the bottom of the tower body 1 and submerge the air inlet of the exhaust pipe 10. This allows the exhaust gas to enter the water first and directly contact the water, forming bubbles that burst on the water surface, and then the gas rises for spraying. The impurity particles in the gas are effectively removed before spraying, thereby improving the subsequent spray purification. Effect: During the rising and spraying process of the exhaust gas in the tower body 1, the motor 8 can drive the spray component 4 to rotate, so that the water spraying is more uniform. At the same time, the rotation of the spray component 4 will drive the stirring component 7 to rotate. The bottom of the stirring component 7 is located in the water accumulated at the bottom of the tower body 1, which can stir the accumulated water, which helps to break up the bubbles, so that the gas and water can contact to remove dust, and at the same time, the centrifugal force is formed to help impurities settle at the bottom of the water. The guide component 6 is set to help guide the flow of exhaust gas, so that the exhaust gas flows to the bottom of the water outlet of the spray component 4, which is convenient for spraying. The venturi tube 501 is set to facilitate the detection of the water flow rate for spraying.

[0022] In a preferred embodiment, the spray assembly 4 includes a main water pipe 401 , a water branch pipe 402 connected to the bottom of the main water pipe 401 , and atomizing nozzles 403 installed on both ends of the inner wall of the bottom of the water branch pipe 402 .

[0023] It should be noted here that the water supply pipe 5 supplies water into the main water pipe 401, the water flows into the branch water pipe 402, and then is atomized and sprayed out from two atomizing nozzles 403 at the bottom of the branch water pipe 402.

[0024] In a preferred embodiment, the guiding assembly 6 includes a guiding ring 601, a guiding column 602 arranged inside the guiding ring 601, a plurality of equally spaced connecting rods 603 connected between the guiding ring 601 and the guiding column 602, and a through hole 604 opened at the top of the guiding column 602.

[0025] It should be noted here that by arranging the guiding column 602 and the guiding ring 601, the rising waste gas can be guided directly below the atomizing nozzle 403.

[0026] In a preferred embodiment, the stirring assembly 7 includes a long rod 701, a cross rod 702 fixed to the bottom of the long rod 701, and a plurality of equally spaced conical blocks 703 fixed to the outer wall of the cross rod 702.

[0027] It should be noted here that the long rod 701 can rotate as the branch water pipe 402 rotates, thereby driving the cross rod 702 and the conical blocks 703 to rotate, and stirring the water accumulated at the bottom inside the tower body 1.

[0028] In a preferred embodiment, the transmission assembly 9 includes a driving wheel 901 fixed to the output shaft of the motor 8, a driven wheel 902 fixed to the main water pipe 401, and a belt 903 drivingly connected between the driving wheel 901 and the driven wheel 902.

[0029] It should be noted here that during spraying, the motor 8 can be driven to drive the driving wheel 901 to rotate, thereby driving the belt 903 and the driving wheel 901 to rotate, further driving the main water pipe 401 to rotate, and further driving the branch water pipe 402 and the two atomizing nozzles 403 to rotate, so that the water mist is sprayed more evenly.

[0030] Working principle: The waste gas can be introduced into the tower body 1 through the waste gas pipe 10. Water can be supplied into the main water pipe 401 through the water supply pipe 5. The water flows into the branch water pipe 402 and is atomized and sprayed out from the two atomizing nozzles 403 at the bottom of the branch water pipe 402 to spray and treat the waste gas. The sprayed water accumulates at the bottom inside the tower body 1. Since the height of the water outlet pipe 12 is higher than the height of the air inlet of the waste gas pipe 10, the water will accumulate to a certain depth at the bottom inside the tower body 1 and submerge the air inlet of the waste gas pipe 10. This enables the introduced waste gas to first enter the water and directly contact with the water. After the bubbles break on the water surface, the gas then rises for spraying. The impurity particles in the gas are effectively removed before spraying, improving the subsequent spraying purification effect. During the process of the waste gas rising and spraying inside the tower body 1, the motor 8 can drive the driving wheel 901 to rotate, thereby driving the belt 903 and the driven wheel 901 to rotate, further driving the main water pipe 401 to rotate, and then driving the branch water pipe 402 and the two atomizing nozzles 403 to rotate, making the water mist spray more evenly. The long rod 701 can rotate along with the rotation of the branch water pipe 402, further driving the cross rod 702 and the conical block 703 to rotate, stirring the water accumulated at the bottom inside the tower body 1, helping to break the bubbles, enabling the gas to contact with the water for dust removal, and at the same time forming a centrifugal force to help the impurities precipitate at the bottom of the water. Through the arranged guiding columns 602 and guiding rings 601, the rising waste gas can be guided directly below the atomizing nozzles 403 for convenient spraying. The Venturi tube 501 is arranged to facilitate the detection of the flow rate of the spraying water.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
