General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification.

[0003] In the process of industrial waste gas treatment, spray towers are used to treat waste gas in most cases. In the process of spray tower treatment of waste gas, the spraying method is used, which is easy to cause foam. If the foam cannot be eliminated in time, it will cause it to cling to the tower wall and gradually stack upwards. If the foam is not eliminated in time, the bacteria in the spray tower will spread outward and affect the safety of the surrounding environment. The use of defoaming agents requires regular addition, which is inconvenient. For this reason, we propose a defoaming structure for spray towers for waste gas treatment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a defoaming structure for a spray tower for waste gas treatment, which solves the problem of foam generated during the spraying process and the inconvenience of multiple additions of defoaming agents proposed in the above background technology.

A piston is movably mounted on the inner cavity of the movable chamber, and a first contraction spring is fixedly installed on the outside of the piston. A driving motor is supported on the outside of the spray tower, an eccentric disk is fixedly installed on the top of the output shaft of the driving motor, and a second contraction spring is fixedly connected to the inner wall of the movable chamber.

[0010] Optionally, the axis of the eccentric disk is located outside the axis of the driving motor, and the inner side of the piston and the outer side of the piston are fixedly connected.

[0011] The utility model provides a defoaming structure for a spray tower for waste gas treatment, which has the following beneficial effects:

[0012] 1. The defoaming structure of the spray tower for waste gas treatment supports multiple air supply pipes with different diameters on the same horizontal plane through the setting of the air supply pipe and the support block.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a defoaming structure for a spray tower for waste gas treatment, comprising four air supply pipes 1 and a spray tower. A support block 2 is fixedly installed on the outer side of the air supply pipe 1. The inner side of the spray tower cylinder wall and the outer end of the outer support block 2 are fixedly connected. The four air supply pipes 1 are located on the same horizontal plane. The setting of the support block 2 plays a role of connecting support, which can support multiple air supply pipes 1 on the same horizontal plane. At the same time, multiple air supply pipes 1 can be supported on the inner side of the cylinder wall, which is convenient for the use of the equipment. At the same time, the setting of the multi-layer air supply pipes 1 can move up and down in batches, thereby assisting in breaking through bubbles. An air supply pipe 3 is fixedly installed on the bottom surface of the air supply pipe 1. The inner cavity of the air supply pipe 1 and the inner cavity of the air supply pipe 3 are interconnected. The inner cavity of the air supply pipe 1 and the inner cavity of the connecting pipe 7 are interconnected. The setting of the air supply pipe 3 plays a role of supporting the movable plug 4. At the same time, the supply The air pipe 3 and the air supply pipe 1 are connected to control the up and down movement of the movable plug 4, and then control the up and down movement of the defoaming cone 5. The up and down movement of the defoaming cone 5 can assist in eliminating bubbles. The inner cavity of the air supply pipe 3 is movably covered with a movable plug 4, and the bottom surface of the movable plug 4 is fixedly connected to the defoaming cone 5. The inner cavity of the defoaming cone 5 and the movable plug 4 is provided with a jet channel 6 that runs through the upper and lower parts. A connecting pipe 7 is fixedly installed above the two spaced air supply pipes 1. The setting of the connecting pipe 7 connects the two spaced air supply pipes 1, and can control the overall defoaming cone 5 to intermittently stab downward during the movement, thereby improving the defoaming efficiency and facilitating the use of the equipment. The opening of the jet channel 6 means that in the defoaming process, the defoaming cone 5 will puncture into the inside of the foam in some cases and cannot eliminate the foam. The air supply of the jet channel 6 can increase the air pressure inside the foam, thereby assisting in bursting the foam.

[0022] See also Figure 5The utility model provides a technical solution: a ventilation pipe 8 is fixedly installed on the outside of the connecting pipe 7, and an active chamber 9 is fixedly connected to the outside of the ventilation pipe 8. The first contraction spring 11 extends outward to the outside of the active chamber 9, and the outer side of the eccentric disk 13 and the outer side of the first contraction spring 11 fit each other. During use, the cooperation of the eccentric disk 13 and the second contraction spring 14 can control the inward and outward reciprocating motion of the first contraction spring 11, thereby controlling the reciprocating motion of the piston 10. During the activity of the piston 10, the change of the air pressure in the inner cavity of the active chamber 9 is controlled, thereby controlling the change of the air pressure in the inner cavity of the air supply pipe 1. The inner cavity of the active chamber 9 is movably sleeved with the piston 10, and the axis of the eccentric disk 13 is located outside the axis of the drive motor 12. The inner side of the piston 10 is fixedly connected to the outer side of the piston 10. During the rotation of the eccentric disk 13, when the eccentric disk 13 rotates close to the spray tower, the eccentric disk 13 will push the first contraction spring 11 to move inward inside the active chamber 9, so that the piston 10 moves inward on the inner side of the active chamber 9, and then the air in the inner cavity of the active chamber 9 is pushed to the inner cavity of the air supply pipe 1 through the ventilation pipe 8, so that the high-pressure air in the inner cavity of the air supply pipe 1 enters the inner cavity of the air supply pipe 3, which can promote the movement of the defoaming cone 5. The first contraction spring 11 is fixedly installed on the outer side of the piston 10, and the drive motor 12 is supported on the outer side of the spray tower. The eccentric disk 13 is fixedly installed on the top of the output shaft of the drive motor 12, and the inner wall of the active chamber 9 is fixedly connected to the second contraction spring 14.

[0023] In summary, the defoaming structure of the spray tower for waste gas treatment, when in use, connects the multi-layer air supply pipe 1 through the support block 2, and at the same time uses the support block 2 to install the air supply pipe 1 inside the spray tower, so that the ventilation pipe 8 extends outward to the outside of the spray tower. During use, the drive motor 12 is controlled to start, and the rotation of the drive motor 12 is used to control the eccentric disk 13 to rotate around the axis of the drive motor 12. During the rotation of the eccentric disk 13, when the eccentric disk 13 rotates close to the spray tower, the eccentric disk 13 will push the first contraction spring 11 to move inward inside the active chamber 9, so that the piston 10 moves inward inside the active chamber 9, and then the air in the inner cavity of the active chamber 9 is pushed to the inner cavity of the air supply pipe 1 through the ventilation pipe 8, so that the high-pressure air in the inner cavity of the air supply pipe 1 enters the air supply pipe 3 The inner cavity of the air supply pipe 1 and the air supply pipe 3 is reduced, thereby driving the movable plug 4 and the jet channel 6 to shrink upward. At the same time, the diameter value of the jet channel 6 is set to be smaller. For some bubbles that have not been punctured, the defoaming cone 5 is extended into the interior of the bubble. The jet from the jet channel 6 is used to create a pressure difference between the inside and outside of the bubble, thereby breaking the bubble. The setting of the connecting pipe 7 can connect the two-layer spaced air supply pipes 1, so that the defoaming cones 5 under the two adjacent air supply pipes 1 intermittently puncture downward, thereby improving the crushing efficiency.
