Problems solved by technology

[0004] However, the current common photocatalytic devices still have many shortcomings, which limit the application of this technology.
The main defects of the current common photocatalytic devices are: using photocatalytic treatment alone, lack of pretreatment and posttreatment means; the device is not easy to disassemble, and the components are difficult to replace
[0007] Both of the above two devices have technical problems such as using photocatalytic treatment alone, lack of pre-treatment and post-treatment means, difficult to disassemble the device, and difficult to replace components.

Embodiment

[0070] Simulate the discharge of typical industrial waste gas, prepare the waste gas whose main pollution factor is toluene, and control the flow rate of the waste gas to 1000m 3 / h, the concentration of toluene is 100mg / m 3 about. If the photocatalytic device shown in the attached figure is established, the device has a total of 3 UV lamp modules, and each module is equipped with 5 UV lamps; the UV lamp is a U-shaped lamp with a length of 810mm, a power of 150w, and a peak wavelength of 254nm. Two photocatalytic modules form the photocatalytic main body section with the ultraviolet lamp module. Water spray modules are installed in the front and back of the photocatalytic main section, and each module is equipped with 3 nozzles at the top, with a spray flow rate of 4.5m 3 / h. The end is a fan module, and the air volume of the fan is 1000m 3 / h, the maximum wind pressure is 1500Pa, equipped with a frequency converter to adjust the flow.

Abstract

The invention discloses a modularized photocatalytic device for organic waste gas treatment and a method. The device comprises a shell, one end of the shell is provided with a gas inlet connected with a gas inlet pipe, the other end of the shell is provided with a gas outlet connected with an exhaust pipe, and the exhaust pipe is connected with a draught fan module; the interior of the shell is sequentially divided into a pretreatment section, a main reaction section and an aftertreatment section in the direction from the gas inlet to the gas outlet, and the interior of the pretreatment section and the interior of the aftertreatment section are each provided with a spraying module; photocatalytic modules and ultraviolet lamp modules are alternately arranged in the main reaction section in the direction from the pretreatment section to the aftertreatment section. According to the treatment device and technology, the photocatalytic treatment efficiency is improved through water spraying pretreatment, the water spraying aftertreatment efficiency is improved through photocatalytic treatment, the waste gas matter can be further removed by adopting water spraying in the aftertreatment workshop section, and all the sections cooperatively act to improve the organic waste gas purifying effect.

Description

technical field [0001] The invention relates to an organic waste gas treatment device and method, in particular to a modularized photocatalytic device and method for organic waste gas treatment. Background technique [0002] Air pollution is one of the most prominent environmental problems in my country at present. Industrial organic waste gas is an important source of air pollutants and endangers human health. In recent years, with the development of society, the improvement of material civilization and living standards, and the enhancement of environmental protection awareness, the environmental pollution caused by the discharge of industrial organic waste gas and its serious harm to human health have become more and more concerned by governments at all levels and the public. Focus. [0003] In recent years, the development of photocatalytic technology in the field of industrial organic waste gas treatment has attracted more and more attention. For example, the Chinese i...
