Problems solved by technology

These odorous dusts will not cause harm to the human body, but in terms of smell, long-term exposure to high concentrations of volatile odors will also cause discomfort to the human body.
[0003] Therefore, the existing fluidized bed is usually equipped with a cyclone dust collector, but the cyclone dust collector can only separate part of the dust, but it is difficult to effectively remove the peculiar smell at the place where the essence and spices volatilize, which still causes people in the surrounding environment to feel unwell

Embodiment 1

[0036] Embodiment 1: as figure 1 Shown, be a kind of chicken bouillon plant waste gas treatment process disclosed by the present invention, comprise the following steps:

[0037] S1: Dust removal, the waste gas discharged from the fluidized bed is passed into the cyclone dust collector 1, and the cyclone dust collector 1 filters the dust in the discharged waste gas,

[0038] When the temperature of the exhaust gas discharged from the fluidized bed is lower than 50 degrees Celsius, the exhaust gas treated by the cyclone dust collector 1 is passed into the dry filter, and the 3D filter in the dry filter is used to perform secondary dust removal on the exhaust gas;

[0039] When the temperature of the exhaust gas discharged from the fluidized bed is between 50 degrees Celsius and 60 degrees Celsius, the exhaust gas treated by the cyclone dust collector 1 is directly passed into the scrubber 6, and the temperature of the exhaust gas is reduced to below 50 degrees Celsius by the sc...

Embodiment 2

[0046]Embodiment 2: as figure 2 As shown, a waste gas treatment system of a chicken bouillon factory includes a cyclone dust collector 1 for initially filtering dust, a photocatalytic oxidation device 2 for oxidizing waste gas, a stable reduction device 3 for reducing waste gas, an induced draft fan 4 for driving the flow of waste gas and The discharge tower 5 for discharging waste gas, the cyclone dust collector 1, the photocatalytic oxidation device 2, the stable reduction device 3, the induced draft fan 4 and the discharge tower 5 are connected in sequence. The photocatalytic oxidation device 2 and the stable reduction device 3 are both equipped with a number of photocatalytic plates and ultraviolet lamps. The surface of the photocatalytic plates is attached with a nano-titanium dioxide catalyst, and the light emitted by the ultraviolet lamps is a vacuum wave. After the exhaust gas discharged from the fluidized bed is pre-filtered by the cyclone separator, the photocatalyt...

Abstract

The invention relates to a chicken essence factory waste gas treatment process and waste gas treatment system, and relates to the technical field of waste gas treatment. The chicken essence factory waste gas treatment process comprises the following steps: S1, dust removal: introducing waste gas discharged by a fluidized bed into a cyclone dust collector, and filtering dust in the discharged wastegas by the cyclone dust collector; S2, oxidation: piping the waste gas treated in the step S1 into a photocatalytic oxidation device, and the photocatalytic plate and the ultraviolet lamp in the photocatalytic oxidation device jointly oxidize the waste gas subjected to dust removal; S3, reduction: piping the oxidized waste gas into a stable reduction device, and the photocatalysis plate and the ultraviolet lamp in the stable reduction device conduct oxidation reduction on the waste gas again; and S4, discharging: discharging the treated waste gas to the high altitude through a discharge towerwith the height of 15 meters. Water in the waste gas is oxidized into hydroxyl radicals and superoxide ion radicals by utilizing the photocatalytic oxidation device, and then the hydroxyl radicals and the superoxide ion radicals react with substances generating peculiar smells in the waste gas to generate carbon dioxide and the like so that the peculiar smells in the waste gas are removed.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment process and a waste gas treatment system of a chicken bouillon factory. Background technique [0002] The chicken bouillon factory needs to use a fluidized bed to dry the product during the production process. During the drying process, the flavor and fragrance in the product will volatilize at high temperature, resulting in dust with a peculiar smell. These odorous dusts will not cause harm to the human body, but in terms of smell, long-term exposure to high concentrations of volatile odors will also cause discomfort to the human body. [0003] Therefore, the existing fluidized bed is usually equipped with a cyclone dust collector, but the cyclone dust collector can only separate part of the dust, but it is difficult to effectively remove the peculiar smell at the place where the essence and spices volatilize, which still causes people in the su...
