Embodiment Construction

[0018] refer to figure 1 An example application of the apparatus and method is illustrated.

[0019] First, fix the device casing in a suitable position, coat the inner wall of the casing and the baffle with a layer of titanium dioxide photocatalytic material, and install the baffle on a figure 1 The position shown will be able to generate ultraviolet rays with the main peak bands of 253.7nm and 184.9nm at the same time, and the lamps are evenly installed inside the device. After the whole device is installed, turn on the power supply. After the device is unloaded for 5 minutes, let the collected odorous gas enter the device through the air inlet. Under the diversion effect of the baffle, the odorous gas moves forward along the baffle and spirals upward. , and finally discharged from the outlet. The residence time of the malodorous gas in the deodorizing device is controlled to 5 seconds, and the field application test is carried out on the gas at the air outlet. The killin...

Abstract

The invention relates to a photolytic deodorization device and a method. The device comprises an air inlet, a shell, a baffle, an ultraviolet light tube and the like. The method for obnoxious gas is realized by the following steps that: firstly a layer of photocatalysis material is coated on the inner wall of the shell and the baffle; the baffle is arranged in an appropriate position; and the light tubes with the quartz glass shell are evenly distributed in the interior of the device. After the device is arranged, the power source is powered; after the device is vacant for 5 minutes, the obnoxious gas comes into the photolytic deodorization device, goes forward along the baffle and spirally climbs, and finally is discharged from a gas outlet. The device and the method can effectively remove the odor, have low operating cost and do not produce the secondary pollution.

Description

technical field [0001] The patent of the present invention relates to an environmental protection device and method, in particular to a device and method for light deodorization of malodorous gas. Background technique [0002] With the continuous development and progress of society, industries such as manufacturing and catering services are increasingly booming, but the toxic and harmful odorous gases emitted by various enterprises every day have greatly polluted the atmospheric space on which we depend. Different production facilities and processes produce a variety of odorous gases. Odors such as ammonia, amines, sulfides, fatty acids, aromatics and dimethyl sulfide are produced during the composting process. Good oxidation and sludge drying process will produce mercaptans, dimethyl sulfide and a small amount of hydrogen sulfide. At present, industrial production, municipal sewage, sludge treatment and garbage disposal facilities are the main sources of these odorous gas...
