Description

TECHNICAL FIELD

[0001] The utility model relates to a cylinder type laboratory low concentration waste gas treatment device. BACKGROUND

[0002] The photo-thermal synergistic catalyst is an adsorption-driven advanced oxidation technology. Through a special synthesis process of catalytic materials and porous materials, the adsorption catalyst material integrates the functions of strengthening enrichment and advanced oxidation. The photo-thermal synergistic catalyst realizes the combination of in-situ regeneration of catalytic materials and catalytic oxidation technology, and is a high-performance purification material. The photo-thermal synergistic catalyst perfectly solves the problems of traditional adsorption materials such as activated carbon in the field of environmental purification, and has the strong performance of the traditional adsorption materials.

[0003] The filter-adsorption device in the existing laboratory photo-thermal synergistic catalysis technology document is an integrated design. The main technical problems are as follows: the traditional integrated device is usually designed as a fixed overall structure. Once the capacity or filtration demand of the device changes, the device needs to be replaced or significantly modified as a whole. The device cannot be flexibly adjusted and expanded. In particular, when treating volatile organic compounds and other pollutants, the adaptability of the filtration device is poor. In the integrated structure, various filtration and catalytic materials are integrated in the same device. The individual modules cannot be flexibly replaced according to actual needs. Therefore, when the pollution load increases or the composition changes greatly, the integrated catalyst or filtration material may not achieve the best purification effect, resulting in fluctuations in purification efficiency.

[0004] Therefore, there is an urgent need in the art for a cylinder type laboratory low concentration waste gas treatment device that can increase or decrease the filter-adsorption units as needed at any time through a modular structure to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the above problems of the prior art and provides a cylinder type laboratory low concentration waste gas treatment device that can increase or decrease the filter-adsorption units as needed at any time through a modular structure. The specific solutions are as follows:

[0006] A cylinder type laboratory low concentration waste gas treatment device includes a support, an inlet mixing chamber, and an outlet mixing chamber. At least one first inlet is provided on the side of the inlet mixing chamber. At least two first outlets are provided on the upper side of the inlet mixing chamber. At least one second outlet is provided on the side of the outlet mixing chamber. At least two second inlets are provided on the upper side of the outlet mixing chamber. A primary purification unit is detachably provided on the upper side of the first outlet. A secondary purification unit is detachably provided on the upper side of the second inlet. The primary purification unit and the secondary purification unit are in communication with each other. The first inlet and the first outlet are provided on different sides of the support. The primary purification unit and the secondary purification unit are both cylindrical in shape. The inlet and outlet can realize multi-channel transmission, improving the gas flow speed and purification efficiency.

[0007] Further, the primary purification unit is provided with a purification light source along the axis of the cylinder, and the secondary purification unit is provided with a purification light source along the axis of the cylinder, and the light source is a 1000mm lamp tube.

[0008] Further, the primary purification unit includes at least two filter adsorption units, each of which is in communication with a first gas outlet.

[0009] Further, the secondary purification unit includes at least two filter adsorption units, each of which is in communication with a second gas inlet.

[0010] Further, the filter adsorption unit has a double-layer shell.

[0011] Further, the double-layer shell is provided with an adsorption material.

[0012] Further, the gas inlet mixing chamber and the gas outlet mixing chamber are both rectangular prisms.

[0013] Further, the first gas inlet, the first gas outlet, the second gas inlet and the second gas outlet are all circular in cross-section.

[0014] In order to further improve the purification performance, the primary purification unit and the secondary purification unit are both provided with a purification light source along the axis of the cylinder, and the light source is a 1000mm lamp tube design, which can photocatalytically decompose VOC gas, and can cooperate with the purification unit of the cylinder to make the light emitted by the light source have no dead angle, and the illumination efficiency is stable. The device also includes at least two filter adsorption units, which correspond to the gas outlets and gas inlets of the primary purification unit and the secondary purification unit, respectively, to realize staged adsorption purification. The shell of the filter adsorption unit is a double-layer shell structure, which is filled with adsorption material, increasing the contact area between the gas and the adsorption material and improving the purification efficiency.

[0015] Beneficial effects: The primary and secondary purification units are detachable, and the modular design facilitates independent replacement and maintenance of each purification unit. When the number of purification modules needs to be increased or decreased, the number of purification units can be flexibly adjusted to improve the flexibility and adaptability of the equipment. By providing primary and secondary purification units, the purification process of VOC gas is divided into multiple stages, which can effectively improve the purification efficiency. The primary purification unit can preliminarily adsorb and filter VOC, while the secondary purification unit can further purify deeply to ensure the thoroughness of VOC treatment and effectively improve the purification effect.
