Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, and in particular relates to an online regenerative waste gas purification device. Background Art

[0002] With the development of economy and the improvement of people's living standards, people pay more and more attention to air quality. Industrial production, fossil fuel combustion and human life process will produce a large amount of toxic and harmful waste gas. The "Comprehensive Emission Standard of Air Pollutants" and "Emission Standard of Malodorous Substances" promulgated by the state and many local laws and regulations have stipulated the emission standard requirements of harmful waste gas, and it is necessary to treat VOCs, nitrogen oxides and malodorous gases discharged into the air. In addition, indoor air pollution is mainly organic matter such as particulate matter, formaldehyde, benzene and microorganisms such as bacteria and viruses. The removal technology of particulate matter is relatively mature, but the removal of VOCs such as formaldehyde, toluene and benzene mostly uses activated carbon adsorption or catalytically active filters to decompose gaseous pollutants. Existing waste gas purification equipment mostly uses fixed packing beds or packing boxes. After a period of use, the waste gas purification materials need to be replaced or the waste gas purification materials need to be removed for activation. The operation is cumbersome, wastes labor, and will also cause secondary pollution. Utility Model Content

[0003] In order to solve the problems existing in the existing waste gas purification equipment, the utility model discloses an online regenerable waste gas purification equipment, which can activate and regenerate the filler in the equipment after being used for a period of time, and can operate continuously for a long period of time, thereby reducing the operating cost and the cost of replacing the filler.

[0004] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions:

[0005] A waste gas purification device that can be regenerated online comprises, from top to bottom, an upper cylinder, a middle cylinder and a lower cone, an ozone generator is provided at the top of the upper cylinder, a gas outlet is provided on the side, a spray water pipe and a spray head are provided at the bottom, the spray water pipe is connected to a high-pressure water tank arranged outside the upper cylinder, the middle cylinder is provided with an upper support plate and a lower support plate, the upper support plate is filled with an upper filler pile at the top, an upper heating rod is arranged in the upper filler pile, the lower support plate is filled with a lower filler pile, a lower heating rod is arranged in the lower filler pile, the upper heating rod and the lower heating rod are connected to a heating control arranged outside the middle box through a wire, a gas buffer chamber is provided between the top of the lower filler pile and the upper support, the lower cone is provided with a waste gas inlet, and the bottom is provided with a sewage outlet.

[0006] Furthermore, the ozone generator is connected to the upper cylinder through a slide rail and can move in the upper cylinder. The ozone generator has an air outlet facing downward and is equipped with a trumpet-shaped ozone diffuser.

[0007] Furthermore, the spray water pipe is a multi-layer concentric ring, evenly distributed on the cross section of the upper cylinder, and the number of the spray heads is multiple, evenly distributed on the spray water pipe.

[0008] Furthermore, the upper support plate and the lower support plate are porous sieve plates with a pore size of 1-3 mm, and a mounting hole is opened on the middle cylinder. The upper support plate and the lower support plate are installed on the middle cylinder by pulling.

[0009] Furthermore, there are multiple upper heating rods, which are evenly distributed in the upper filler pile, and the bottoms of the upper heating rods extend deep into the lower part of the upper filler pile.

[0010] Furthermore, the height of the gas buffer chamber is 10-20 cm.

[0011] Furthermore, the sewage outlet is provided with an electric sewage valve.

[0012] The online regenerable waste gas purification equipment described in the utility model, waste gas containing VOCs or odor enters from the waste gas inlet at the bottom of the equipment, after being buffered by the lower cone, the waste gas is dispersed by the lower support body and enters the lower packing pile, and continues to flow upward after being adsorbed or decomposed by the waste gas purification material, and enters the upper packing pile after passing through the gas buffer chamber. The setting of the gas buffer chamber can greatly reduce the bed resistance, and the upper packing pile and the lower packing pile can use different packings to enhance the removal effect of VOCs and odors. After using for a period of time, stop the waste gas from entering, turn on the ozone generator in the upper cylinder, use an external fan to purge the inside of the equipment from top to bottom, so that the generated ozone flows from top to bottom through the upper packing layer and the lower packing layer, and the VOCs and other harmful gases adsorbed by the packing are oxidized online to regenerate the packing. In order to enhance the oxidation and regeneration process of pollutants in the packing, the upper and lower heating rods can be turned on to heat the packing layer and increase the oxidation speed. After the equipment has been used for a period of time, the surface of the filler will be covered with particles, reducing the removal efficiency of harmful gases. The spray device can be turned on to flush the filler to remove the dust on the surface of the filler. After flushing, turn on the heating rod to heat and dry the filler.
