Description

TECHNICAL FIELD

[0001] The utility model relates to waste gas treatment technical field, concretely is a kind of waste gas treatment equipment's flow guide structure. BACKGROUND

[0002] In modern industrial production process, waste gas emission is a problem that cannot be ignored. Waste gas treatment, also known as waste gas purification, aims to pretreat the waste gas generated in industrial places such as factory workshops before external discharge to ensure that the national waste gas emission standard is met. Waste gas treatment covers organic waste gas treatment, odor waste gas treatment, air sterilization and disinfection purification and other aspects. At present, the common waste gas treatment equipment flow guide structure is mostly a simple flow guide plate design. The existing flow guide plate can only change the direction of gas flow and cannot control the flow rate. In the waste gas treatment process, if the flow rate is too fast, the waste gas and the treatment reagent or treatment device do not contact for enough time, and the treatment is not sufficient, resulting in poor treatment effect. If the flow rate is too slow, it will reduce the treatment efficiency and affect the overall production progress.

[0004] According to the above description, the applicant believes that the following problems exist:

[0005] The waste gas treatment equipment flow guide structure uses corrugated pipe, adjusting mechanism and the like to realize the flow guide work.

If the flow rate is too fast, the waste gas and the treatment reagent or treatment device do not contact for enough time, and the treatment is not sufficient, resulting in poor treatment effect. If the flow rate is too slow, it will reduce the treatment efficiency. Therefore, the structure needs to be improved. UTILITY MODEL CONTENTS
