Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to an organic waste gas pretreatment structure and collection and treatment equipment. Background Art

[0002] Organic waste gas generally contains volatile organic compounds (VOCs) such as formaldehyde and toluene, which are flammable, explosive, toxic, harmful, insoluble in water but soluble in organic solvents. Common methods for treating organic waste gas include activated carbon adsorption, catalytic combustion, catalytic oxidation, acid-base neutralization, plasma, etc.

[0003] In the prior art, organic waste gas is generally transported to the treatment equipment through a pipeline for treatment. Part of the organic waste gas will adhere to the inside of the pipeline and cannot enter the treatment equipment, resulting in a large gap between the total amount of organic waste gas that needs to be treated and the total amount of organic waste gas actually treated, thereby reducing the treatment effect of the organic waste gas. Especially in the arc section or bend section of the pipeline, the degree to which the organic waste gas adheres to the inside of the pipeline is higher than that to the inside of the straight pipe section, thereby further affecting the treatment effect of the organic waste gas.

[0010] Furthermore, when projected along the length direction of the pipeline, the cross section of the adsorption layer covers the cross section of the internal space of the pipeline.

[0011] Furthermore, the installation space runs through the pipeline arrangement.

[0012] Furthermore, the installation space has a step for abutting and limiting the installation frame.

[0017] Furthermore, the installation space has at least an opening facing the outside of the bending section.

[0028] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0030] The following is combined with Figure 1 To Attachment Figure 4 The specific implementation modes of the present utility model are described in detail.

[0031] In an embodiment of the utility model, an organic waste gas pretreatment structure is provided, including a pipeline 1, a mounting frame 3 and an adsorption layer 4. One end of the pipeline 1 is an organic waste gas inlet, and the other end is an organic waste gas outlet. The outlet end can be connected to an organic waste gas treatment device, and the pretreated organic waste gas can be passed into the treatment device for deep treatment. Specifically, an installation space 2 is opened in the pipeline 1, and the installation space 2 is connected to the internal space of the pipeline 1, and the installation space 2 has at least one side opening. The mounting frame 3 can be installed in the installation space 2 and detachably connected to the pipeline 1, and the adsorption layer 4 is installed on the mounting frame 3. In the installed state, the direction in which the adsorption layer 4 penetrates the mounting frame 3 is consistent with the length direction of the pipeline 1. When the organic waste gas flows through the installation space 2, it can continue to flow along the pipeline 1 and flow out from the outlet end after being adsorbed by the adsorption layer 4.

[0032] When the installation space 2 has only a single-sided opening, the mounting frame 3 can be inserted from the opening of the installation space 2; when the installation space 2 runs through the pipeline 1, that is, the installation space 2 has double-sided openings, the mounting frame 3 can be inserted and installed from any side opening of the installation space 2, which is more flexible and convenient, and it is also easy to observe the state of the mounting frame 3 after it is installed in the installation space 2. If the mounting frame 3 is in an inclined state after installation, it affects the pretreatment effect of the adsorption layer 4. At this time, the installation state of the mounting frame 3 can also be adjusted in time.

[0033] In a further configuration, the installation space 2 is provided with a step 5 for abutting against the position-limiting mounting frame 3, which limits and positions the installation position of the mounting frame 3. After the mounting frame 3 abuts against the step 5, the outer surface of the mounting frame 3 remains flush with the outer surface of the pipe 1, which can also improve the aesthetics. The step 5 and / or the abutting surface of the mounting frame 3 are provided with corrugations to extend the path of gas leakage from the gap between the step 5 and the mounting frame 3, thereby achieving the effect of improving the sealing and anti-leakage. In addition, the mounting frame 3 and the step 5 are connected by fasteners, making full use of the step 5. Specifically, screw holes are processed at the corresponding parts of the step 5 and the mounting frame 3 to penetrate the connecting bolt fasteners (not shown). In addition, to ensure the sealing performance, the bolt fasteners are provided with sealing members such as sealing rings or other sealing structures.

[0034] In this embodiment, the installation space 2 is opened through the pipeline 1, and steps 5 are set at the openings on both sides of the installation space 2. In order to prevent the steps 5 in the installation space 2 from hindering the installation of the mounting frame 3, the mounting frame 3 and the installation space 2 are both set in a conical shape. During installation, the narrow end of the mounting frame 3 is first inserted from the opening on the wider side of the installation space 2. At this time, the step 5 at the opening on the wider side of the installation space 2 will not hinder the mounting frame 3 until the narrow end of the mounting frame 3 abuts against the step 5 at the opening on the narrow side of the installation space 2, and at the same time, the wide end of the mounting frame 3 abuts against the step 5 at the opening on the wider side of the installation space 2, thereby completing the abutment installation of the mounting frame 3 and the pipeline 1.

[0035] In this embodiment, the adsorption layer 4 uses activated carbon commonly used in the treatment of organic waste gas and is installed on the mounting frame 3. It can be installed in the installation space 2 together with the mounting frame 3. Since the installation space 2 is connected to the internal space of the pipeline 1, the organic waste gas will flow through the installation space 2 when flowing inside the pipeline 1. The organic waste gas is pre-treated and adsorbed by the adsorption layer 4 located in the installation space 2, thereby reducing the concentration of the organic waste gas flowing in the pipeline 1 and reducing the adhesion of the organic waste gas to the inner wall of the pipeline 1 in the form of condensation, crystallization, etc., thereby improving the treatment effect of the organic waste gas. The lower the concentration of the organic waste gas in the pipeline 1, the lower the probability of the organic waste gas contacting the inner wall of the pipeline 1, and the less the amount of adhesion to the inner wall of the pipeline 1. Therefore, the position of the adsorption layer 4 in the pipeline 1 is generally close to the inlet end of the pipeline 1. In addition, when projected along the length direction of the pipeline 1, the cross section of the adsorption layer 4 covers the cross section of the internal space of the pipeline 1, so that the organic waste gas can all flow through the adsorption layer 4 for pretreatment, thereby ensuring the pretreatment effect.

[0036] It should be noted that the purification rate of organic waste gas can reach more than 95% after being adsorbed by activated carbon, and the adsorption layer 4 in the pipeline 1 is only for pretreatment, and the purification rate requirement for organic waste gas is relatively low. For deep-level organic waste gas purification, it can be carried out through subsequent processing equipment. In addition, factors that affect the purification rate of activated carbon include the number of pores of activated carbon, the density of activated carbon, etc. In the adsorption layer 4 in the pipeline 1, activated carbon with a small number of pores and low density can be selected to achieve the effect of pretreatment, and the production cost of activated carbon is also low. In different factory environments, the length and path of pipeline 1 are different. When the length of pipeline 1 is long, multiple pretreatment structures will be set on pipeline 1. At this time, the adsorption layer 4 of activated carbon with a small number of pores and low density is used, which can also further reduce the production cost pressure of adsorption layer 4.

[0037] The pipeline 1 generally has a straight section and a bend section to suit different application scenarios. In this embodiment, the pipeline 1 has at least one bend section, and the pipeline 1 opens an installation space 2 at the bend section, so that the organic waste gas is pretreated at least in the bend section of the pipeline 1. When the organic waste gas flows through the bend section in the pipeline 1, due to the action of centrifugal force, the organic waste gas is more concentrated on the outside of the bend section (i.e., the side protruding toward the bend), making the organic waste gas adhere to the inner wall of the pipeline 1 more seriously than the inner wall, so it is necessary to set a pretreatment structure in the bend section of the pipeline 1.

[0038] In addition, the installation space 2 has at least an opening toward the outside of the bending section, so that the installation frame 3 can be installed from the outside of the bending section into the installation space 2, with a wider installation field of view and simpler installation. In this embodiment, the installation space 2 is opened through the pipe 1 along the radial direction of the bending section, and steps 5 are provided at the openings of the installation space 2 toward the outside and inside of the bending section. In order to avoid the step 5 at the outside opening of the installation space 2 hindering the installation of the installation frame 3, the installation frame 3 and the installation space 2 are both provided in a conical shape. During installation, the narrow end of the installation frame 3 is first inserted from the outside opening of the installation space 2. At this time, the step 5 at the outside opening of the installation space 2 will not hinder the installation frame 3 until the narrow end of the installation frame 3 abuts against the step 5 at the inside opening of the installation space 2, and at the same time, the wide end of the installation frame 3 abuts against the step 5 at the outside opening of the installation space 2, thereby completing the abutment installation of the installation frame 3 and the pipe 1.

[0039] As for the adsorption layer 4, since the organic waste gas at the bend section is easily gathered outside the bend section in the internal space of the pipeline 1, the adsorption layer 4 is also set in a cone shape, so that the thickness of the adsorption layer 4 outside the bend section is greater than the thickness inside the bend section. Specifically, the thickness of the adsorption layer 4 along the length direction of the pipeline 1 is d, wherein the thickness d of the adsorption layer 4 gradually increases from the inside of the bend section to the outside of the bend section, so that the adsorption capacity of the adsorption layer 4 pointing to the outside of the bend section is greater than the adsorption capacity of the adsorption layer 4 pointing to the inside of the bend section, thereby making the adsorption of the organic waste gas by the adsorption layer 4 more uniform.

[0040] The utility model also discloses an organic waste gas collection and treatment device, comprising the above-mentioned organic waste gas pretreatment structure, wherein the device body for deep-level treatment of organic waste gas is communicated with the outlet of the pipeline 1.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0043] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
