Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail:

[0024] Specific examples, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a combined VOCs purification and recovery device includes an adsorption chamber, and the device includes a coaxially arranged shell 1 and a first heat insulation partition 3, and the first heat insulation partition 3 is vertically arranged on the shell 1 and separate the cavity in the housing 1 into at least two adsorption chambers. The first heat insulation partition 3 is a double-layer metal partition, and there is a heat insulation layer in the middle of the double-layer metal partition. The material of the heat insulation layer is composite Silicate, ceramic fiber, asbestos or aluminum silicate, the heat insulation layer is easy to obtain, low cost, good heat insulation effect, and can ensure that the temperature between adjacent adsorption chambers does not...

Abstract

The invention relates to a combined type VOCs (Volatile Organic Chemicals) purification and recovery device, which comprises absorption cavities. The device comprises a shell and a first heat-insulation clapboard which are arranged coaxially; the first heat-insulation clapboard is arranged in the shell along the vertical direction and divides a cavity in the shell into at least two adsorption cavities; each adsorption cavity is internally provided with a fixed bed adsorption bed layer; gas-phase holes are formed in the bottom part and the top part of the shell; the two gas-phase holes are formed coaxially with the shell and are communicated with all adsorption cavities; the gas-phase hole in the bottom part of the shell is an organic waste gas and desorption gas inlet; the gas-phase hole in the top part of the shell is an organic waste gas and desorption gas outlet. The combined type VOCs purification and recovery device can achieve the aims of continuously carrying out adsorption and desorption operation in one shell at the same time, realizes integration of organic waste gas adsorption and adsorbing material desorption processes, and has the characteristics of simplification in technology process, simplicity in operation, high automation degree, low cost and the like. Multiple sets of equipment are reduced to be one set of equipment, so that the occupied area is greatly reduced, and the space is saved.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and relates to a combined VOCs purification and recovery device. Background technique [0002] In industrial industries, such as packaging and printing, oil refining and petrochemicals, electronic product manufacturing, automobile manufacturing, painting and maintenance, etc., a large amount of waste gas containing VOCs (volatile organic compounds) will be emitted during the production process. If it is directly discharged into the atmosphere, Not only will it cause air pollution and personnel poisoning, but it will also lead to waste of materials and increase production costs. In recent years, as the problem of environmental pollution has become increasingly prominent, the smog problem in various places has seriously affected people's daily life. According to the analysis of the causes of smog, VOCs emissions account for a large part. The government and environmental protection organiz...
