preparation example Construction

[0030] The concrete preparation method of the honeycomb runner of above-mentioned two runner structures, comprises the following steps:

[0031] Step 1. Select one or more mixtures of ceramic fiber, glass fiber, synthetic fiber or natural fiber to make paper, and extrude it into paper with concave-convex surface after papermaking. The paper with concave-convex surface is made of inorganic adhesive A binder such as silica sol or aluminum sol is bonded on flat paper to form a layered body, and the layered body is stacked or wound into a honeycomb profile;

[0032] Step 2, cutting the obtained profile into a desired shape, heating to remove part of the organic matter, and obtaining two carriers with a porous honeycomb structure as runner one and runner two;

[0033] Step 3: Mix 0.1-30 parts of molecular sieve, 0.1-30 parts of catalyst with 0.1-30 parts of inorganic binder and 10-60 parts of water to obtain adsorbent slurry and catalyst slurry;

[0034] Step 4, attaching the obta...

Embodiment 1

[0043] In this embodiment, combined with figure 1 As shown, the process of adsorption and purification of VOCs and catalytic oxidation through the honeycomb runner includes:

[0044] Step 1. VOCs1 are first adsorbed and concentrated through the adsorption zone 5, and the waste gas is purified and emptied 2;

[0045] Step 2. The runner gradually tends to adsorption saturation. In the desorption zone, high-temperature air (open valve 28 and heat the air through the heater) passes through the saturated runner, and the adsorbed waste gas is desorbed 3 and directly enters the Catalytic zone 6 carries out catalytic oxidation process;

[0046] Step 3. The gas after catalytic oxidation carries part of the heat, which can be used as desorption gas to save part of the heat;

[0047] Step 4, the runner is cooled by the atmosphere 4, so that the runner can continuously perform the process of adsorption purification and catalytic oxidation.

[0048] The heat balance of the system in thi...

Abstract

The invention discloses a honeycomb rotating wheel with combination of adsorbent purification and catalytic oxidation for VOCs, and belongs to the field of VOCs purifying technology. The honeycomb rotating wheel is composed of a rotating wheel 1 and a rotating wheel 2, the diameters of the rotating wheel 1 and the rotating wheel 2 are identical, wherein, the rotating wheel 1 is uniformly attached with an adsorbent for forming an adsorption zone, the rotating wheel 2 is uniformly attached with a catalyst for forming a catalysis zone, the rotating wheel 1 and the rotating wheel 2 are coaxially connected, and the rotating wheel 2 is positioned at an inlet side of VOCs; or the honeycomb rotating wheel is composed of a rotating wheel 1, wherein, the rotating wheel 1 is provided with an adsorption zone and a catalysis zone, the adsorption zone is uniformly distributed with adsorbents, and the catalysis zone is uniformly distributed with catalysts. The honeycomb rotating wheel comprises two units, after VOCs are adsorbed and purified, the VOCs directly enter into the catalytic oxidation zone, after catalysis treatment, the VOCs reach the standard and are discharged; two units are integrated for working, so the treatment efficiency is improved; the rotating wheel volume is small, the land occupation area is small and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of VOCs purification, in particular to a honeycomb runner combined with VOCs adsorption purification and catalytic oxidation. Background technique [0002] VOCs are volatile hydrocarbons and their derivatives, including hydrocarbons, aromatic hydrocarbons, alcohols, aldehydes, ketones, esters, amines, organic acids, etc. VOCs are easy to accumulate in fat-rich tissues, and most of them are carcinogenic, teratogenic, and mutagenic, and are potentially harmful to the environment. It is following SO 2 After , NOx and Freon, it is another focus of exhaust gas pollution that countries all over the world pay attention to. A variety of VOCs have been listed as priority control and priority monitoring pollutants by the US National Environmental Protection Agency. my country also has strict regulations on the emission of VOCs in industrial and mining enterprises, requiring relevant enterprises to deal with VOCs whe...
