Description

Technical Field

[0001] The invention relates to the field of waste gas treatment, and in particular to a self-supporting waste gas discharge device based on tower skirt design calculation. Background Art

[0002] Industrial waste gas contains many kinds of pollutants, their physical and chemical properties are very complex, and their toxicity varies. The waste gas discharged from fuel combustion contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc.; due to different raw materials and processes used in industrial production, various harmful gases and solid wastes are emitted, containing various components such as heavy metals, salts, and radioactive substances; the exhaust gas emitted by automobiles contains hydrocarbons such as lead, benzene and phenol. Waste gas pollution of the atmospheric environment is one of the most common and serious environmental problems in the world. Industrial waste gas includes organic waste gas and inorganic waste gas. Organic waste gas mainly includes various hydrocarbons, alcohols, aldehydes, acids, ketones and amines; inorganic waste gas mainly includes sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds.

[0003] Industrial waste gas generally needs to be treated to meet the safety emission standards before it can be safely discharged. However, when discharged, industrial waste gas usually contains impurities with larger and smaller particle sizes. When treating, since larger particle size impurities can easily cause filter blockage, it is usually necessary to treat the larger particle impurities first, and then treat the small particle size impurities in the waste gas. However, when treating larger particle impurities, since the particles are larger, the frequency of blockage of the interceptor is greater, affecting the waste gas treatment efficiency.

[0004] The invention patent with application number 201911372118.6 discloses an exhaust gas purification tower. It includes a tower body, an air inlet pipe and a sewage pipe are arranged on the tower body, a grid, a spray pipe, an activated carbon layer and a demister are arranged in the tower body, a lower liquid hopper is arranged in the tower body below the air inlet pipe, the lower liquid hopper includes a lower liquid port, and a transmission device is arranged below the lower liquid hopper; the transmission device includes an impeller, a rotating shaft, a turntable, a pull rope, a fixed rod, a rotating wheel and a lower pressure block. The present invention causes the impeller to rotate and generate power by causing sewage to fall onto the impeller, and drives the lower pressure block to move up and down, so as to evenly mix the dust and particles contained in the sewage at the sewage outlet. At the same time, when the lower pressure block moves upward, it can drive part of the sewage to flow back in a small range, that is, to generate suction at the sewage outlet, which helps to clean the sewage outlet and prevent blockage.

[0005] The above technology discharges and treats soluble impurities, but in the actual production process, there will be some insoluble impurities (such as metal particles, iron filings, etc.) mixed in the sewage. These insoluble impurities may be deposited in the front position of the sewage outlet, that is, the position where the liquid flows between the liquid bucket and the sewage outlet, usually a liquid reservoir. The liquid in the liquid bucket is first collected in the liquid reservoir, and then pumped to the sewage outlet through a pump. The purpose of adding a liquid reservoir is to prevent liquid backflow, that is, the pumping power of the pump is insufficient, or it is temporarily broken, causing the liquid to pile up and flow back to the air inlet. However, insoluble impurities are easily accumulated in the liquid reservoir, and a technology is needed to regularly clean the insoluble impurities in the liquid reservoir. Summary of the invention

[0006] The invention provides a self-supporting exhaust gas discharge device based on tower skirt design calculation, which can regularly clean insoluble impurities in a liquid storage tank.

[0007] In order to solve the above problems, the present invention provides: a self-supporting exhaust gas discharge device based on the design and calculation of a tower skirt, comprising a cylinder body, an air inlet is opened on one side of the cylinder body, a grille is fixedly arranged in the cylinder body above the air inlet, a liquid pipe is arranged above the grille, a plurality of nozzles are arranged on the liquid pipe, the liquid pipe is fixedly connected to the cylinder body, a liquid bucket is arranged in the cylinder body below the air inlet, a liquid storage tank is arranged below the liquid bucket, a liquid outlet is arranged on one side of the liquid storage tank, an air outlet is also arranged on the top of the cylinder body, and also comprises a tower base and a lead screw, the tower base is fixedly connected to the cylinder body, the liquid storage tank is arranged in the tower base, a first nozzle and a second nozzle are opened below the liquid bucket, both ends of the lead screw are rotatably connected to the inner wall of the tower base, a plurality of buffer plates are coaxially fixed on the lead screw, and the buffer plates are evenly distributed on the outside of the lead screw to form a rotating cylinder, the first There is an angle between the nozzle and the second nozzle. When liquid is discharged from the first nozzle, it is used to push the rotating drum to move clockwise, and when liquid is discharged from the second nozzle, it is used to push the rotating drum to rotate counterclockwise. The lead screw near the liquid outlet is also slidably connected to a ball seat, and a scraper plate is fixedly connected below the ball seat. A push switch is fixed on the inner wall of the tower seat near the liquid outlet and at the initial position of the ball seat. An actuator is also connected in series with the push switch in the same circuit. The actuator is connected to a water baffle, and the actuator controls the water baffle to cover the first nozzle and the second nozzle. When the push switch near the liquid outlet is squeezed by the ball seat, the second nozzle is opened, the rotating drum rotates counterclockwise, and the ball seat moves toward the rotating drum. When the push switch at the initial position of the ball seat is squeezed, the first nozzle is opened, the rotating drum rotates clockwise, and the ball seat moves toward the liquid outlet.

[0008] The basic principle and beneficial effects of this scheme are as follows: the cylinder body is fixed on the ground by a tower base, and the air inlet is used to introduce the exhaust gas to be discharged. The exhaust gas carries some water-insoluble impurities into the cylinder body, and the liquid pipe sprays water through the nozzle. The water and impurities are mixed, and the weight of the impurities is increased and falls into the liquid bucket, and the gas continues to flow upward to the air outlet to be discharged. The grille can also prevent impurities from moving upward with the gas. Two nozzles are arranged below the liquid bucket, namely the first nozzle and the second nozzle; there is an angle between the first nozzle and the second nozzle, that is, the first nozzle and the second nozzle face two directions respectively, and the rotating drum composed of the lead screw and the buffer plate arranged below the nozzle can rotate when being flushed by water from the nozzle, and at the same time drive the lead screw to rotate, and the ball seat slides with the rotation of the lead screw, driving the scraper plate to move. The push switch is set at the initial position of the ball seat and the position of the liquid outlet. When the push switch near the liquid outlet is squeezed by the ball seat, the second nozzle opens, the drum rotates counterclockwise, and the ball seat moves toward the drum. When the push switch at the initial position of the ball seat is squeezed, the first nozzle opens, the drum rotates clockwise, and the ball seat moves toward the liquid outlet. That is, when the ball seat squeezes a push switch, the actuator controls the water baffle to block the current nozzle and release the other nozzle, so that the drum formed by the buffer plate rotates in the opposite direction, and the ball seat also moves in the opposite direction, forming a rule. When a push switch is squeezed, the ball seat moves in the opposite direction.

[0009] The drum formed by the buffer plate in this solution can rotate in two directions, and impurities attached to the buffer plate can be thrown out during the reversing process to prevent accumulation. When the drum rotates, the water flow from the nozzle hits the buffer plate. If it only rotates in one direction, the long-term water flow hitting will cause concentrated wear of the buffer plate and directional deformation. Through the setting of this solution, it can be intermittently stressed from two directions, which can slow down the wear.

[0010] The scraper plate in this solution can disturb the water flow when it reciprocates, and push the water in the liquid storage tank to flow toward the liquid outlet. When the scraper plate moves toward the liquid outlet, the scraper plate provides a boost force, which can push some insoluble impurities attached to the liquid storage tank to flow toward the liquid outlet. When the scraper plate moves in the opposite direction, it can push the water flow in the opposite direction from the middle, and the water level on both sides of the scraper plate rises, which can immerse impurities at higher positions. Push it into the water and wait to be washed away. When the scraper plate moves in the opposite direction, it can drive part of the sewage to flow back in a small range, that is, generate suction at the outlet of the sewage pipe, which is more conducive to the discharge of sewage on both sides.

[0011] Furthermore, a spoiler is included, and the spoiler is arranged between the gas outlet and the liquid pipe.

[0012] Furthermore, it also includes an activated carbon layer, which is arranged between the spoiler and the liquid outlet pipe.

[0013] Furthermore, the spoiler includes a spoiler with axial fins and a spoiler with spiral fins.

[0014] Beneficial effect: It can slow down or prevent the resonance of the cylinder body when exhaust gas is discharged.

[0015] Furthermore, it also includes a demister fixed between the air outlet and the spoiler.

[0016] Furthermore, the liquid storage tank is arranged to be inclined to the liquid outlet.

[0017] Beneficial effect: It is convenient and better to discharge sewage from the storage tank.

[0018] Furthermore, the rotating drum is composed of three buffer plates, and the interval between adjacent buffer plates is 120 degrees. BRIEF DESCRIPTION OF THE DRAWINGS
