Description

Technical Field

[0001] The utility model relates to the technical field of deodorization equipment, in particular to plasma deodorization equipment for a garbage transfer station. Background Art

[0002] During the operation of municipal facilities such as garbage transfer stations, food waste treatment plants, existing garbage treatment plants, and sewage treatment plants, large amounts of gases containing malodorous substances such as hydrogen sulfide, ammonia, and mercaptans are generated. If these odors are directly discharged, they will harm the health of surrounding residents and damage the ecological environment. Therefore, these odors need to be treated.

[0003] Pulse plasma deodorization equipment utilizes the principle of gas discharge to eliminate pollutants, odors, and organic matter. High-voltage ionization of the air generates plasma, causing free radicals and ions in water vapor and oxygen to polymerize to form odor-causing intermediates. These are then oxidatively degraded, ultimately achieving the desired deodorization effect. Compared to other plasma technologies, pulse plasma boasts a higher charge density and electron energy, generating significant electron impact and bombardment, further enhancing air treatment capabilities. Pulse plasma deodorization equipment is widely used in industries such as environmental protection, printing, coatings, chemicals, pharmaceuticals, and food. For example, in public places like underground garages, garbage dumps, and restrooms, where odors and pollution are common, pulse plasma deodorization equipment can effectively reduce the levels of harmful gases and odor molecules in the air, improving air quality. In the printing, coatings, and chemical industries, where organic pollutants are likely to be emitted, pulse plasma deodorization equipment can effectively eliminate odors and purify harmful gases.

DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0035] Example 1

[0036] like Figure 1 、 2 As shown in FIG3 and FIG4, a plasma deodorization device for a garbage transfer station includes a tank body 1, wherein a filtering mechanism 3, a pulse deodorization mechanism 21 and a spraying mechanism 11 are sequentially arranged inside the tank body 1 from the inlet to the outlet; the pulse deodorization mechanism 21 adopts the existing technology, namely the following Figure 2 As shown, the pulse deodorization mechanism 21 includes an electrode plate 211 and a high-voltage pulse power supply 212 for providing high-voltage pulses to the electrode plate 211; Figure 2 In the embodiment, the electrode plate 211 is a bent plate-shaped structure, which has a better treatment effect. The electrode plate 211 includes a high-voltage electrode and a grounding electrode. The high-voltage electrode and the grounding electrode can establish an electric field, thereby generating plasma, and utilizing the plasma to achieve deodorization;

[0037] The principle of plasma deodorization is: high voltage ionization of air generates plasma, which is a plasma state composed of electrons, ions, free radicals and excited molecules, and then decomposes malodorous substances and harmful gases in the air. The details are as follows:

[0038] Process 1: Direct bombardment of high-energy electrons produces ion-electron plasma;

[0039] Process 2: Oxidation of O atoms or ozone in electron plasma; O2+e- →2O;

[0040] Process 3: Oxidation of OH radicals H2O+e - →OH - +H;H2O+O→2OH;H+O2→OH+O;

[0041] Specifically, when a high-voltage pulse power source 212 (e.g., with a maximum boost voltage of 40 kV to 60 kV) is applied to the electrodes, a strong electric field is generated between the electrodes. This electric field is sufficient to ionize gas molecules, generating a large number of electrons, ions, and free radicals. These active species are highly chemically active and can react with odor molecules in the air (such as hydrogen sulfide, ammonia, and volatile organic compounds), breaking them down into harmless or less harmful substances, such as water, carbon dioxide, and other inorganic substances.

[0042] The filtering mechanism 3 is perpendicular to the inner wall of the tank body 1 and includes a first filter plate 31 and a second filter plate 32. The first filter plate 31 is slidably connected to the inner wall of the tank body 1, and the second filter plate 32 is fixed to the tank body 1.

[0043] The first filter plate 31 is fixed by three groups of first plates, each group of first plates includes two filter plates fixed at a certain angle, the angle = 90°,

[0044] The second filter plates 32 include six groups of second plates, each group of second plates includes two filter plates connected by a torsion spring 322, and the openings formed by the two filter plates in each group of second plates correspond one to one with the openings formed by the two filter plates in each group of first plates;

[0045] The spray mechanism 11 includes a spray pipe and a spray head vertically arranged in the tank body 1;

[0046] The tank body 1 is provided with a first box body 2, the first box body 2 is communicated with the interior of the tank body 1, and the pulse deodorization mechanism 21 is located in the first box body 2;

[0047] The inlet end of the first box body 2 is connected to the tank body 1, and the outlet end of the first box body 2 is arranged on the side wall of the first box body 2 above the tank body 1. A second box body is provided on the tank body 1, and the second box body is connected to the first box body 2, and the bottom surface of the second box body is connected to the tank body 1;

[0048] An air intake fan 33 is provided at the inlet of the tank body 1. The air intake fan 33 is rotatably connected to the inner wall of the tank body 1 via a rotating rod. The side of the shaft of the air intake fan 33 is rotatably connected to one end of the rotating rod, and one end of the shaft is connected to the output shaft of the motor fixed in the tank body 1.

[0049] The included angle of the second plate is 80°, and the upper and lower end edges of the second plate are slidably connected to the inner side wall of the opening of the first plate. The upper and lower end edges of the second plate are provided with brush blocks 321, and the brush blocks 321 are provided with through holes. The connection between the two filter plates of the second plate is connected to the tank body 1 through a connecting rod 323; the other end of the shaft is provided with a first bevel gear 34, and the tank body 1 is provided with a second bevel gear 35 that meshes with the first bevel gear 34. The second bevel gear 35 is connected to the tank body 1 through a fixing rod, one end of the fixing rod is fixed to the second bevel gear 35, and the other end of the fixing rod is rotatably connected to the inner wall of the tank body 1. The fixing rod is provided with a cam 36 for moving the first filter plate 31.

[0050] The working method of the above device is:

[0051] First, the motor and the air intake fan 33 are turned on to draw the gas to be deodorized into the tank body 1. As the air intake fan 33 rotates, it drives the first bevel gear 34 to rotate, which in turn drives the second bevel gear 35 to rotate, which in turn drives the cam 36 to rotate. The cam 36 pushes the first filter plate 31. The first filter plate 31 and the second filter plate 32 move relative to each other, and the scraper 321 on the second filter plate 32 cleans and scrapes the inner wall of one side of the first filter plate 31 to prevent impurities in the intake air from clogging the first filter plate 31. The gas then enters the pulse deodorization mechanism 21 for deodorization. When the high-voltage pulse power supply 212 is turned on and the electrode plate 211 is energized, plasma is generated in the air. The plasma reacts with odor molecules (such as hydrogen sulfide, ammonia, and volatile organic compounds), breaking them down into harmless or low-harm substances. These substances and the air are finally purified by the spray mechanism 11 and discharged from the tank body 1.
