Description

Technical Field

[0001] The present application relates to an organic waste gas treatment device, and in particular to a multi-element ionization process deodorization device. Background Art

[0002] Waste gas emissions are unavoidable byproducts of industrial production, energy conversion, and daily life. These emissions often contain harmful chemicals, particulate matter, volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), and other substances, posing a serious threat to the environment and human health. Therefore, waste gas treatment technologies have become a key issue in the environmental protection field, aiming to reduce or eliminate the emission of these harmful substances.

[0003] Currently, waste gas treatment technologies are mainly divided into three categories: physical, chemical and biological methods. Each type of technology has its own specific application scenarios and limitations.

[0004] Physical methods include filtration, adsorption, condensation, and membrane separation. Filtration primarily removes particulate matter from exhaust gas; adsorption uses adsorbents such as activated carbon to capture gaseous pollutants; condensation lowers the temperature to condense gaseous pollutants into a liquid state for subsequent treatment; and membrane separation utilizes the selective permeability of semipermeable membranes to separate different components in exhaust gas.

[0005] Chemical methods include catalytic oxidation, acid-base neutralization, chemical absorption, and combustion. Catalytic oxidation uses a catalyst to accelerate the chemical reaction of harmful gases, converting them into harmless substances. Acid-base neutralization is used to treat acidic or alkaline waste gases. Chemical absorption uses an absorbing liquid to react with pollutants in the waste gas to achieve purification. Combustion is suitable for treating combustible waste gases, converting them into harmless carbon dioxide and water through high-temperature combustion.

[0006] Biological methods: Utilize the metabolic activity of microorganisms to degrade organic pollutants in waste gas, such as biofilters and biotrickling filters. Biological treatment methods have the advantages of low operating costs and no secondary pollution, but treatment efficiency is affected by various factors such as microbial species, temperature, and humidity.

[0007] Although there are many types of waste gas treatment technologies available, there are still many challenges:

[0008] Processing efficiency: Some technologies have low processing efficiency and are unable to meet increasingly stringent environmental protection standards;

[0009] Energy consumption and cost: Some technologies have high energy consumption and high operating costs, which limits their widespread application;

[0010] Secondary pollution: Secondary pollution may occur during the adsorbent regeneration process and needs to be properly handled;

[0011] Adaptability: The composition of different exhaust gases is complex and changeable, and a single technology cannot cope with all situations.

[0012] Therefore, how to realize efficient treatment of waste gas is an important technical problem to be solved at present. Practical new type content

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application.

[0038] Specifically, if Figure 1-3 As shown, a multi-element ionization process deodorization device is provided in an embodiment of the present application, which mainly includes a bag dust removal device 100, a spray device 200 and a deodorization device 300. After the organic waste gas is dust-removed by the bag dust removal device 100, it enters the spray device 200 and absorbs the organic waste gas by spraying water. Finally, after the odor is removed by the deodorization device 300, it returns to the spray device 200 for further reaction.

[0039] The above process is specifically as follows:

[0040] The bag dust removal equipment 100 is connected to the exhaust gas outlet pipe 110, so that the exhaust gas enters the bag dust removal equipment 100 through the exhaust gas outlet pipe 110. A dust removal chamber 120 is provided in the bag dust removal equipment 100, and an electrostatic plate 130 is installed in the dust removal chamber 120. There are multiple electrostatic plates 130 in the dust removal chamber 120, and the multiple electrostatic plates 130 are arranged parallel to each other and installed corresponding to the position of the exhaust gas outlet pipe 110, so that the exhaust gas can be directly blown onto the electrostatic plate 130 when entering the bag dust collector, so that the static electricity on the electrostatic plate 130 can adsorb the particles on the exhaust gas and filter and remove dust from the exhaust gas.

[0041] In the above description, the bag dust removal equipment 100 includes a bag dust collector.

[0042] Among them, in the above structure, when the types of exhaust gas are different, the static electricity size on the electrostatic plate 130 needs to be appropriately adjusted according to the type of particles in the exhaust gas. Specifically, multiple electrostatic plates 130 are connected to the controller, and the controller can control the static electricity size on the electrostatic plate 130 to capture particles in the exhaust gas. During the capture process, the controller adjusts the static electricity size on the electrostatic plate 130 according to the gas composition detected by the gas detector installed in the outlet pipe 110 to achieve targeted adsorption of the exhaust gas.

[0043] In this application, in order to better adsorb the exhaust gas, the electrostatic plate 130 needs to be rotated, specifically:

[0044] A rotating motor 150 is installed on the bag dust collector, and a turntable 160 is provided on the output end of the rotating motor 150. The turntable 160 is arranged in the dust removal chamber 120. A plurality of electrostatic plates 130 are installed on the turntable 160, so that the turntable 160 can drive the electrostatic plates 130 to rotate, making it convenient for each position of the electrostatic plates 130 to be blown by the exhaust gas, thereby achieving an efficient dust removal effect.

[0045] In order to facilitate blowing of the exhaust gas, a fan 140 is provided at the position corresponding to the exhaust pipe 110 on the bag dust collector, that is, the fan 140 is installed at the air inlet of the bag dust collector so that the exhaust gas can be driven by the fan 140 to be blown onto the electrostatic plate 130.

[0046] After the exhaust gas is dust-removed by the bag dust removal equipment 100, it enters the spray equipment 200. A spray chamber 210 is opened on the spray equipment 200. A rotating nozzle 220 is arranged in the spray chamber 210. The rotating nozzle 220 is installed at the top position in the spray chamber 210, and the rotating nozzle 220 is connected to the rotating motor 230, so that the rotating motor 230 can drive the rotating nozzle 220 to rotate and spray in the spray chamber 210.

[0047] A plurality of nozzles 221 are provided on the rotating spray head 220 in a direction toward the spray chamber 210 . The plurality of nozzles 221 are evenly arranged on the rotating spray head 220 .

[0048] In the present application, the water sprayed by the rotating nozzle 220 is a spray liquid, which is a tap water. Before entering the spray equipment 200, the oxidizing gas is introduced into the tap water to form an external spray liquid. When the spray liquid enters the spray chamber 210, the spray liquid reacts preliminarily with the exhaust gas to neutralize and absorb the acidic gases (such as SO2, etc.) in the exhaust gas to form a water-gas mixture.

[0049] After the waste gas is sprayed, the waste gas enters the deodorization device 300. In this application, the deodorization device 300 is a super ion integrated deodorization system, which is provided with an ion generator 310. The ion generator 310 generates polyvalent ions (such as hydroxyl radicals (OH)) through low-pressure ionization. - ), single oxygen (O - ), hydrogen ions (H + ), oxygen (O2), ozone (O3), etc.).

[0050] Through multi-element ions, a series of oxidation-reduction, neutralization, adsorption and other reactions can be carried out on odorous substances in the water-gas mixture to decompose and remove the odorous substances.

[0051] After the exhaust gas is deodorized, the water-gas mixture enters the spraying equipment 200 through the reflux pipe 320 for a secondary reaction. After entering the reflux pipe 320, the water-gas mixture enters the rotating nozzle 220. The rotating nozzle 220 sprays the water-gas mixture into the spray chamber 210, so that the odorous substances in the odorous gas further react with the ionized substances in the spray liquid, and are decomposed and removed.

[0052] In order to improve the secondary reaction process, in the present application, a plurality of contact plates 240 are provided in the spray chamber 210. The contact plates 240 are evenly arranged in the spray chamber 210, and the plurality of contact plates 240 are all provided at the bottom of the rotating spray head 220.

[0053] A groove 241 is provided on each contact plate 240 , and the groove 241 is filled with a filler. The filler can increase its surface area to enhance the contact area between the odorous gas and the spray liquid, thereby improving the reaction efficiency.

[0054] In order to ensure a certain reaction efficiency, the specific surface area of ​​the filler in this application is 132m 2 / m 3 .

[0055] In the embodiment of the present application, the filler is specifically a polypropylene filler.

[0056] After secondary treatment, the exhaust gas is discharged through the outlet of spray equipment 200, completing the exhaust gas treatment process. Online monitoring equipment is installed at the outlet of spray equipment 200 to monitor real-time parameters such as the concentration of odorous substances, temperature, humidity, and air volume in the exhaust gas. The monitoring equipment uses high-precision sensors (such as electrochemical sensors and optical sensors). The monitoring data is transmitted to the monitoring computer in the central control room via a data acquisition system. Operations and maintenance personnel can view the monitoring data in real time through monitoring software to ensure that emissions comply with relevant environmental standards.

[0057] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
