Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieves, in particular to a waste gas treatment molecular sieve corrugated body structure. Background Art

[0002] At present, zeolite wheel, zeolite drum and zeolite fixed bed are new equipment with better treatment effect in waste gas treatment adsorption and desorption in today's environmental protection industry. Its core component: molecular sieve adsorption and desorption body, which is mainly composed of molecular sieve, glass fiber carrier and other adhesives, is synthesized into composite adsorption material through special equipment and processed into honeycomb carrier structure, so that the gas containing waste gas components can pass through and be purified.

[0003] However, the channel of an ordinary zeolite wheel is a straight-through structure. Although it can effectively treat exhaust gas, during use, due to long-term use, the efficiency of exhaust gas adsorption may be reduced, affecting the effect of exhaust gas treatment, thereby reducing the quality of exhaust gas treatment.

[0004] In view of this, we propose a molecular sieve corrugated structure for waste gas treatment. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings and provide a waste gas treatment molecular sieve corrugated body structure in which channels and small pits are combined into a Venturi structure.

[0006] The two small pits on multiple channels are arranged in an irregular shape and combined with multiple channels to form a Venturi structure, thereby improving the passing conditions of the exhaust gas to be purified and improving the purification efficiency of the exhaust gas.

[0007] Therefore, the utility model provides a waste gas treatment molecular sieve corrugated body structure, which includes a molecular sieve body, wherein the molecular sieve body is combined with a high temperature resistant substrate to form a molecular sieve carrier, and the molecular sieve carrier is in the shape of a corrugated single-sided paper. The surface of the molecular sieve carrier is provided with a plurality of channels, and the upper surfaces of the plurality of the channels are each provided with two small pits, wherein: the two small pits constitute a variable diameter of the channel, forming a Venturi structure, which is used to improve the passing conditions of the waste gas to be purified, thereby improving the purification efficiency of the waste gas.

[0008] As a further improvement of the technical solution, the high temperature resistant substrate is any one of glass fiber paper, high temperature alloy and inorganic compound material.

[0009] As a further improvement of the technical solution, the two small pits on the multiple channels are arranged in an irregular shape.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the corrugated structure of the molecular sieve for waste gas treatment, two small pits on multiple channels are arranged in an irregular shape and combined with multiple channels to form a Venturi structure, which changes the fluid flow rate of the flow section and forms a change in fluid pressure, allowing the waste gas fluid to better contact with the molecular sieve adsorption and desorption body on the corrugated molecular sieve carrier to achieve better adsorption and desorption effects, and improve the passing conditions of the waste gas to be purified, thereby improving the purification efficiency of the waste gas and improving the quality of waste gas treatment.

[0020] The channel of an ordinary zeolite wheel is a straight-through structure. Although it can effectively treat exhaust gas, during use, due to long-term use, the efficiency of exhaust gas adsorption may be reduced, affecting the effect of exhaust gas treatment, thereby reducing the quality of exhaust gas treatment.

[0021] See also Figure 1-Figure 5 The embodiment of the utility model shown in the figure comprises a molecular sieve body 1, which is combined with a high temperature resistant substrate to form a molecular sieve carrier 2, and the molecular sieve carrier 2 is in the shape of a corrugated single-sided paper, and a plurality of channels 3 are provided on the surface of the molecular sieve carrier 2, and two small pits 4 are provided on the upper surface of the plurality of channels 3, wherein: the two small pits 4 constitute a variable diameter of the channel 3, forming a venturi structure, which is used to improve the passing conditions of the exhaust gas to be purified, thereby improving the purification efficiency of the exhaust gas.

[0022] The working principle of the above Venturi structure is as follows:

[0023] When gas or liquid flows in the venturi tube, at the narrowest part of the pipe, the dynamic pressure velocity head reaches the maximum value, the static pressure rest pressure reaches the minimum value, and the velocity of the gas and liquid increases due to the change in the cross-sectional area of ​​the flow. The entire flow must experience the process of pipe contraction at the same time, so the pressure also decreases at the same time. This generates a pressure difference, which is used to measure or provide an external suction to the fluid.

[0024] Since the molecular sieve needs to be used for a long time to treat the exhaust gas, in order to increase the service life, the high temperature resistant substrate adopts any one of glass fiber paper, high temperature alloy and inorganic compound material.

[0025] The improvement lies in that the high temperature resistant substrate preferably adopts glass fiber paper material, and glass fiber paper has high strength and rigidity. At the same time, the glass fiber paper material is also corrosion-resistant, wear-resistant, high temperature-resistant and cold-resistant. Therefore, the service life of the molecular sieve carrier 2 can be improved and the efficiency of exhaust gas adsorption can be increased.

[0026] In order to improve the efficiency of exhaust gas adsorption, the two small pits 4 on the multiple channels 3 are arranged in an irregular shape.

[0027] The improvement lies in that the two small pits 4 on the multiple channels 3 are arranged in an irregular shape and combined with the multiple channels 3 to form a Venturi structure. By changing the fluid flow rate of the flow section, a change in fluid pressure is formed, allowing the exhaust gas fluid to better contact with the molecular sieve body 1 adsorption and desorption body on the corrugated molecular sieve carrier 2, so as to achieve a better adsorption and desorption effect.

[0028] In summary, the working principle of this scheme is as follows: First, a molecular sieve carrier 2 is made of a molecular sieve body 1 and a high temperature resistant substrate by special equipment. During the process: the waste gas adsorption molecular sieve body 1 with different components is mixed with different active agents, curing agents, etc. to form different slurries, which are then coated on the molecular sieve carrier 2 by an infiltration coating equipment to form a molecular sieve carrier 2 in the shape of corrugated single-sided paper, and then combined and bonded to form a geometric three-dimensional structure molecular sieve carrier 2 substrate, which is a shape that is convenient for equipment installation and use, thereby completing the production of the waste gas treatment molecular sieve corrugated body structure.
