Description

Technical Field

[0001] This utility model relates to the technical field of flue gas purification equipment, and in particular to a negative ion current flue gas pollutant purification and extraction system. Background Technology

[0002] Currently, mechanical purification equipment is widely used for the extraction and treatment of indoor smoke, including oil fumes, suspended dust, polluted exhaust gas, and fresh air exchange. This typically involves setting up grates such as baffles, filters, or metal mesh covers, so that the smoke collides and adheres to the grates, thus separating and removing it from the airflow.

[0003] The aforementioned purification equipment has several drawbacks: low collection efficiency for small-diameter oil fume particles, no odor removal function, and a low oil fume purification rate, typically only 10-20%. The aerosol particles formed by the extracted oil fumes are almost unprocessable, and when released outdoors, they remain suspended in the air, impacting the surrounding atmospheric environment. Studies show that in oil fume particles emitted from catering sources, PM2.5 accounts for over 80% of PM10, and PM1.0 accounts for 50%–85% of PM2.5.

[0004] Therefore, there is an urgent need in this field for a new purification and treatment device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a negative ion flow flue gas pollutant purification and extraction system to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A negative ion electrostatic precipitator flue gas pollutant purification and extraction system includes, in sequence, a bar screen oil stain remover, a cooling dust collector, a negative ion mixing reaction device, an electrostatic precipitator purification device, and an end-stage bio-zeolite exhaust gas filter. The bar screen oil stain remover has an inlet pipe at its inlet end, and the cooling dust collector is also connected to the negative ion mixing reaction device via the inlet pipe. The negative ion mixing reaction device includes, from top to bottom, a negative ion exciter module, an electrocatalytic mixing reaction module, and a negative ion reaction chamber module. A hydroxyl-based water mist generator is also installed at the inlet of the negative ion mixing reaction device. The electrostatic precipitator purification device includes an electrostatic precipitator module and an electrode plate non-plasma reactor module, and also includes a power supply device to provide power to the negative ion mixing reaction device and the electrostatic precipitator purification device.

[0007] As a preferred technical solution, a one-way air intake valve is provided on the air intake pipe to facilitate control of the timing and flow rate of the flue gas to be treated entering the pipe.

[0008] As a preferred technical solution, the bar screen oil stain remover includes a corrugated oil stain removal bar screen and a cyclone exhaust fan, wherein the cyclone exhaust fan is located near the inlet of the bar screen oil stain remover.

[0009] As a preferred technical solution, the power supply device is a high-voltage pulse power supply module.

[0010] As a preferred technical solution, an intermediate swirling mixing zone is provided between the negative ion mixing reaction device and the electrostatic purification device, and a swirling exhaust fan is also provided in the intermediate swirling mixing zone.

[0011] As a further preferred technical solution, the outlet of the terminal bio-zeolite exhaust gas filter is also connected to a centrifugal exhaust fan via a pipeline, and an electric gate valve is installed on the pipeline.

[0012] As a further preferred technical solution, an electric current circulation return pipe is also provided. One end of the electric current circulation return pipe is connected to a centrifugal exhaust fan, and the other end is connected to the air inlet of the electric current purification device through a pipe.

[0013] The main working principle of the processing system of this utility model is as follows: Utilizing a super-gaseous electron flow module, high-energy electrons are generated through continuous pulses of ultra-high voltage and low current, which react with water vapor to produce strong oxidizing hydrogen-oxygen anion free radicals (O). - / OH - / H3O2 - Negative ions, due to their small particle size and high activity, possess extremely strong antioxidant, reducing, and diffusive properties. Negative ions react with waste gas molecules SO2 / NO... X When pollutants react, inelastic collisions occur, converting energy into the internal energy of ground-state molecules. This leads to a series of processes such as excitation, dissociation, and ionization, which can adsorb gas molecules, activating the gas and enabling chemical oxidation-reduction reactions to decompose it into carbon dioxide and water. This eliminates the need for additional back-end treatment equipment such as oil-water separation, high-voltage electrostatic pyrolysis, and adsorption materials, resulting in no material loss, low energy consumption, and prevention of secondary pollution.

[0014] The main chemical reactions that generate free radicals / hydroxyl negative ions in high-voltage modules are: H₂O + e → H₂O - + OH - O2 + e → 2O - O - + H2O → 2OH - 3H - + 3O2 → H3O2 - .

[0015] Compared with the prior art, the advantages of this utility model are as follows: the treatment system of this utility model has a short treatment process for various flue gases, good treatment effect, thorough removal without secondary pollution, low energy consumption operation, no need for consumables such as filter screens and activated carbon, saving operating costs, convenient operation and maintenance, low operating cost, and easy promotion and application.

The electrostatic precipitator 4 includes an electrostatic precipitator module 12 and an electrode plate non-plasma reactor module 13, and also includes a high-voltage pulse power supply module 14 that provides power to the negative ion mixing reaction device 3 and the electrostatic precipitator 4. In this embodiment, a one-way air intake valve 17 is provided on the air intake pipe 16; The bar screen oil stain remover 1 is a vortex collision type bar screen oil stain remover, including a corrugated oil stain removal bar screen 5 and a vortex exhaust fan 7, wherein the vortex exhaust fan 7 is located near the inlet of the bar screen oil stain remover 1. An intermediate vortex mixing zone 11 is provided between the negative ion mixing reaction device 3 and the electrostatic purification device 4. A vortex exhaust fan 7 is also provided in the intermediate vortex mixing zone.

The centrifugal exhaust fan 18 serves as a system for tiered series exhaust, reducing equipment blockage. An electric gate valve 19 is installed on the pipeline. An element flow circulation return pipe 20 is also provided. One end of the element flow circulation return pipe 20 is connected to the centrifugal exhaust fan 18, and the other end is connected to the air inlet of the element flow purification device 4 through a pipe for recycling.

[0019] It should be noted that, unless otherwise specified, all the above-mentioned components are existing technologies known to those skilled in the art and can be obtained through commercial purchase or other means.

Under negative pressure, it is guided through the inlet pipe 16 and enters the negative ion mixing reaction device 3 and the electrostatic precipitator 4 at a flow rate of 1.0-2.0 m / s. Under the action of negative ions and electrostatic precipitators, the flue gas undergoes inelastic collisions, converting energy into the internal energy of ground-state molecules, resulting in a series of reaction processes such as excitation, dissociation, and ionization. The high voltage and low current operation is extremely energy-saving, with high electron kinetic energy and strong destructive power against organic and toxic gases. When the average electron kinetic energy exceeds the chemical bond binding energy of pollutant molecules, the molecular bonds break, the pollutants decompose, and finally decompose into carbon dioxide and water, completing the flue gas purification process.
