Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a ventilation device for sewage treatment. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. It is also increasingly entering the daily lives of ordinary people. During the process of treating sewage in a sewage treatment plant, pungent odors will be emitted. Due to the odors emitted by this sewage, the control quality in the sewage treatment plant is relatively poor. Therefore, some specific ventilation devices are needed to purify the air quality in the sewage treatment plant. Traditional ventilation devices have high energy consumption and may require a large amount of energy consumption to provide a power system, resulting in high operating costs. Moreover, traditional filters are fixed in the ventilation duct, and it is very inconvenient to replace the filters. For this reason, we have proposed a ventilation device for sewage treatment.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a ventilation device for sewage treatment, which has the following beneficial effects:

[0017] 1. Through the design of the plugging component, the device can achieve precise control and adjustment of the air flow at the air outlet. This means that in different usage scenarios, the flow rate and speed of the air flow can be adjusted according to needs to meet specific ventilation, heat dissipation, or other air flow requirements. The device adopts a modular design, and each component is connected through standardized interfaces and connectors, enabling easy disassembly and installation of a new component when a certain component needs to be replaced without large-scale disassembly of the entire device. When replacement is needed, one air outlet is plugged by the plugging component, and at the same time, the adapter pipe is released to direct the air flow in other directions, and a section of the air duct behind the plug is replaced. In scenarios where a smaller air flow rate is required, the rotation speed of the fan blades can be reduced or some air outlets can be closed to reduce energy consumption. In scenarios where a larger air flow rate is required, the device can respond quickly and provide sufficient air flow to ensure the normal operation of related equipment or systems, thereby improving the overall energy efficiency.

[0018] 2. Precise control of the air flow can reduce wear and tear of components such as fan blades, thereby extending the service life of the equipment. The auxiliary connection and adjustment mechanisms (such as clamping blocks, movable clamping blocks, and springs) enable the plugging pipe to be finely adjusted or adapted to different installation environments, further enhancing the flexibility of air flow control. By precisely controlling the flow rate and speed of the air flow, unnecessary energy waste can be avoided. Brief Description of the Drawings
