Description

Technical Field

[0001] The present application relates to the technical field of air purification equipment, and in particular to an exhaust device for convenient and rapid replacement of activated carbon media. Background Art

[0002] In the daily production process, a lot of waste gas may be generated, especially for biochemical production such as chemical plants, which are the main sources of waste gas. These waste gases generated in the production process need to be treated before they can be discharged. Secondly, if these waste gases are in some productions with gas purification requirements, they will be sucked into the wind system as fresh air. Therefore, whether it is the discharge of production or the fresh air inhalation of the purification system, these waste gases should be treated. In the existing waste gas treatment, activated carbon is often used as one of the treatment processes due to its good adsorption, but it needs to be replaced after reaching the adsorption limit. In the existing wind system, drawers are used to hold activated carbon, so it is convenient and fast to replace it. For example, a rapid exhaust device for ammonia production with the authorization announcement number CN 215711817 U uses a drawer to hold activated carbon, and then replaces it after reaching the adsorption limit. However, an open drawer is used to load activated carbon for quick replacement after adsorption. The activated carbon is either bulked in the drawer or bagged through a soft gauze and then loaded in the drawer. For bulk items, the drawer can only be loaded forward, and the drawer cannot be set sideways. For activated carbon transported in soft gauze, the drawer can be placed sideways, but it is still inconvenient to put it into the drawer if it is too full, and it is easy to pile up downwards during use, leaving the upper space empty, causing the adsorption part to fail.
