Description

Technical Field

[0001] This utility model relates to the field of air pollution control technology, specifically to an energy-saving and environmentally friendly air pollution control device. Background Technology

[0002] Air pollution control is a systematic and complex project involving multiple measures and technologies, aiming to reduce the emission of air pollutants, improve air quality, and protect the ecological environment and human health. In order to reduce the emission of harmful substances, energy-saving and environmentally friendly air pollution control devices are needed to treat industrial waste gas. Most current air pollution control devices consist of a filtration chamber, an electrostatic dust removal chamber, a photocatalytic oxidation chamber, an activated carbon adsorption chamber, and a heat recovery chamber.

[0003] The filter chamber of existing air pollution control devices is crucial. It is essential to filter large particulate matter in the exhaust gas to facilitate subsequent treatment. However, using a filter screen can lead to blockage over time, affecting the flow of flue gas and the filtration effect. While existing air pollution control devices can clean the filter screen, the cleaning is incomplete, and it is difficult to collect the cleaned particulate matter. As a result, particulate matter remains in the filter chamber, requiring subsequent cleaning and affecting the cleaning effect. Therefore, we propose an energy-saving and environmentally friendly air pollution control device. Utility Model Content

[0025] Working Principle: Industrial waste gas enters the filter chamber 1 through the inlet pipe 6. With the cooperation of two sets of filter screens 2 with different pore sizes, particulate matter in the waste gas is removed. Then, the waste gas enters the electrostatic precipitator chamber 7, where even smaller particles are adsorbed and removed. Next, it enters the photocatalytic oxidation chamber 8, where, using photocatalysts such as titanium dioxide as the core, ultraviolet irradiation excites the photocatalysts to generate highly oxidizing free radicals. These free radicals oxidize and decompose harmful gases in the air, such as sulfur dioxide, nitrogen oxides, and volatile organic compounds (VOCs), into harmless carbon dioxide, water, and other small molecules, thus achieving the oxidation of gaseous gases. The system deeply purifies pollutants and then uses the activated carbon adsorption layer in the activated carbon adsorption chamber 9 to adsorb the small amount of harmful gases and odor molecules remaining after photocatalytic oxidation, further improving air quality and ensuring that the emitted air meets high standards of cleanliness. At the same time, the activated carbon can be regenerated or replaced regularly to ensure adsorption performance. Then, the heat exchanger in the heat recovery chamber uses the waste heat of the exhaust air to preheat the cold air entering the device, improving energy utilization efficiency, reducing the energy consumption required for heating the air, realizing energy recovery and recycling during the operation of the device, reducing overall operating costs, and conforming to the concept of energy conservation and environmental protection.

[0026] When it is necessary to clean the particles on the surface and inside the mesh of the filter screen 2, the electric telescopic rod 33 drives the lifting plate 32 to move up and down. The lifting plate 32 drives the connecting rod 31 and the cleaning brush 34 to move up and down. The cleaning brush 34 can clean the surface of the filter screen 2. At the same time, the motor 56 drives the drive gear 57 to rotate. The drive gear 57 drives the driven gear 58 to rotate. The driven gear 58 drives the drive shaft 50 and the drive pulley 55 to rotate. The belt 54 and the driven pulley 52 can drive the driven shaft 53 to rotate. With the cooperation of the driven shaft 53 and the drive shaft 50, the two sets of cams 51 can be driven to rotate. The cams 51 can indirectly knock the filter screen 2. With the cooperation of the external dust pump, the dust suction pipe 40 and the dust suction nozzle 41 can collect the cleaned particles.
