Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a chemical waste gas recovery and treatment device. Background Art

[0002] The chemical waste gas recovery and treatment device is a device system specially used to treat waste gas generated in the chemical production process. These waste gases usually contain components that are harmful to the environment and human body, such as volatile organic compounds (VOCs), toxic gases, odorous substances, etc. In order to meet environmental protection standards and reduce air pollution, the chemical industry generally uses activated carbon adsorption boxes. The activated carbon adsorption box uses the physical adsorption characteristics of activated carbon to adsorb harmful substances in the waste gas, thereby achieving the purpose of purifying and recycling the waste gas.

[0003] In a traditional activated carbon adsorption box, activated carbon is usually placed in a pull-out drawer or tray for easy replacement and maintenance. In order to prevent exhaust gas from overflowing through the side panels, top or bottom gaps of the drawer without being adsorbed by activated carbon, the drawer and the box must be effectively sealed. In order to further ensure the sealing between the drawer and the box, the drawer is usually fixed with a mechanical locking device after it is pushed into place. For example, a bolt, a buckle or a handle locking device is used to press the drawer against the box to ensure that the sealing strip is fully compressed to achieve airtightness. Therefore, when replacing the activated carbon in the drawer in large quantities, all drawers need to be opened and closed separately. Each replacement of activated carbon needs to be strictly carried out in accordance with the sealing and locking steps. The operation process is relatively cumbersome and is prone to poor sealing or improper locking due to operational errors. In addition, each drawer needs to be opened separately, the activated carbon replaced, resealed and locked. If the activated carbon adsorption box has multiple drawers, this process will be very time-consuming and require a lot of manpower. For large-scale industrial applications, this operation method will significantly increase time and labor costs. Utility Model Content
