Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas treatment device and its treatment process for the production of multi-layer rubber products. Background Technology

[0002] The waste gases generated during the production of multi-layer rubber products mainly include volatile organic compounds, sulfides, nitrogen oxides, dust and other harmful substances. These waste gases mainly come from rubber vulcanization, rubber mixing, calendering and other processes, and have strong irritant and toxic properties, posing a serious threat to the production environment, employee health and the surrounding ecological environment.

[0003] Currently, the waste gas generated during the production of multi-layer rubber products is mainly treated by spray washing. However, in the existing technology, the waste gas generated by multi-layer rubber products is more complex in composition and has a relatively higher impurity content compared to the waste gas generated by ordinary rubber products. When using the existing spray washing device, the spray liquid is prone to insufficient contact with the waste gas, resulting in poor waste gas treatment effect. In addition, the spray washing device is usually equipped with an activated carbon layer to adsorb harmful gases in the waste gas. However, the activated carbon particles in the activated carbon layer are in a static state, resulting in slow adsorption efficiency.

[0004] Combining the above issues, we find that existing waste gas treatment equipment on the market is difficult to simultaneously avoid the problems mentioned above when in use. Even if it can solve them, it requires the assistance of external tools, thus failing to achieve the desired effect.
