Description

Technical Field

[0001] This utility model relates to the field of production water treatment technology, specifically to a waste gas collection device for water treatment ponds. Background Technology

[0002] In the production water treatment section, the treated biochemical water reacts with acidic agents to produce VOCs waste gas. If the waste gas is not collected and accumulates over a long period of time, it will cause odor to escape and fill the working environment with foul-smelling gases. Therefore, the water treatment tank needs to be covered.

[0003] Traditional direct covering methods cannot actively collect exhaust gases and often rely solely on natural diffusion, resulting in low treatment efficiency. In addition, the cost of independently adding exhaust gas treatment equipment is high and it is difficult to be compatible with existing VOCs treatment systems. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water treatment pond exhaust gas collection device to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: a waste gas collection device for a water treatment tank includes a treatment tank body, which is divided into several treatment areas by partitions. Each treatment area is provided with a fiberglass cover plate at its upper end, and each fiberglass cover plate has a through hole at its upper end. A branch pipe is provided at the through hole, and a main pipe is connected to the end of the branch pipe. The main pipe is connected to a VOCs negative pressure collection device through an exhaust device.

[0006] Preferably, the ventilation device is an induced draft fan.

[0007] Preferably, the partition is made of C30 concrete.

[0008] Preferably, the number of processing areas is four, and the number of partitions is three.

[0009] Preferably, the upper end of the partition is provided with a T-shaped beam, which abuts against the fiberglass cover plate.

[0010] Preferably, the T-beam includes a horizontal beam and a vertical beam, the side end face of the vertical beam abuts against the side wall of the fiberglass cover plate, and the lower end face of the horizontal beam abuts against the upper end face of the fiberglass cover plate.

[0011] Preferably, the side of the vertical beam is provided with a rubber sleeve, and the surface of the rubber sleeve is curved.

[0012] This utility model has the following beneficial effects:

[0013] 1. This waste gas collection device for the water treatment tank generates negative pressure after the exhaust equipment is started. Under the action of negative pressure, the waste gas in each treatment area enters the branch pipe through the through holes of the fiberglass cover plate, and is then transported to the VOCs negative pressure collection device through the main pipe, thus completing the process of waste gas collection and transmission. This realizes the active collection of waste gas in the water treatment tank, changing the traditional passive method of simply covering the tank and relying on natural diffusion. It improves the efficiency of waste gas collection, effectively prevents the problem of odor emission caused by long-term accumulation of waste gas, greatly reduces the odor in the workshop, and improves the working environment.

[0014] 2. A T-shaped beam is provided at the upper end of the partition, which abuts against the fiberglass cover plate. The T-shaped beam enhances the stability of the fiberglass cover plate installation, allowing it to be stably installed above the processing area. It also helps to improve the sealing between the fiberglass cover plate and the partition. The T-shaped beam includes a horizontal beam and a vertical beam. The side end face of the vertical beam abuts against the side wall of the fiberglass cover plate, and the lower end face of the horizontal beam abuts against the upper end face of the fiberglass cover plate. Through the multi-faceted contact between the horizontal beam and the vertical beam and the fiberglass cover plate, the support force and positioning accuracy of the cover plate are further improved, ensuring that the fiberglass cover plate will not shift or shake after installation.

[0015] 3. The sides of the vertical beam are equipped with rubber sleeves. The surface of the rubber sleeves is curved and elastic. When installing the fiberglass cover plate, the curved design can reduce the friction between the cover plate and the vertical beam, so that the cover plate can be installed more smoothly. At the same time, the elastic rubber sleeves can compensate for minor errors in the installation process and fit tightly against the side wall of the fiberglass cover plate.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0026] Example 1:

[0027] A waste gas collection device for a water treatment tank includes a treatment tank body 1, which is divided into several treatment areas 3 by a partition 2. Each treatment area 3 is provided with a fiberglass cover plate 4 at its upper end. Each fiberglass cover plate 4 has a through hole 5 at its upper end. A branch pipe 6 is provided at the through hole 5. The end of the branch pipe 6 is connected to a main pipe 7. The main pipe 7 is connected to a VOCs negative pressure collection device 11 through an exhaust device 8.

[0028] When using this device, the exhaust equipment 8 generates negative pressure after starting. Under the action of negative pressure, the exhaust gas in each treatment area 3 enters the branch pipe 6 through the through hole 5 of the fiberglass cover plate 4, and is then transported to the VOCs negative pressure collection device through the main pipe 7, thereby completing the process of exhaust gas collection and transmission. This realizes the active collection of exhaust gas in the water treatment tank, changing the traditional passive method of simply covering the tank and relying on natural diffusion. It improves the efficiency of exhaust gas collection, effectively prevents the problem of odor emission caused by long-term accumulation of exhaust gas, greatly reduces the odor in the workshop, and improves the working environment.

[0029] In this embodiment, the exhaust device 8 is an induced draft fan. The induced draft fan generates airflow through the rotation of the impeller, forming a stable negative pressure environment, which provides power for the flow of exhaust gas in the branch pipe 6 and the main pipe 7.

[0030] In this embodiment, the material of the partition 2 is C30 concrete. C30 concrete has high strength and durability. In the treatment tank body 1, the partition 2 uses its own structural strength to withstand the pressure of the liquid in the treatment tank and the weight of the fiberglass cover plate 4, and maintain the partition structure of the treatment area 3.

[0031] In this embodiment, there are four treatment zones 3 and three partitions 2. The four treatment zones 3 can realize the phased operation of water treatment. For example, different water treatment processes can be carried out in different treatment zones 3, and the exhaust gas generated in each zone is collected through its respective branch pipe 6.

[0032] In this embodiment, a T-shaped beam 9 is provided at the upper end of the partition 2. The T-shaped beam 9 abuts against the fiberglass cover plate 4. The T-shaped beam 9 enhances the stability of the fiberglass cover plate 4 during installation, enabling the fiberglass cover plate 4 to be stably installed above the processing area 3. It also helps to improve the sealing between the fiberglass cover plate 4 and the partition 2.

[0033] In this embodiment, the T-beam 9 includes a horizontal beam 91 and a vertical beam 92. The side end face of the vertical beam 92 abuts against the side wall of the fiberglass cover plate 4, and the lower end face of the horizontal beam 91 abuts against the upper end face of the fiberglass cover plate 4. Through the multi-faceted contact between the horizontal beam 91 and the vertical beam 92 and the fiberglass cover plate 4, the supporting force and positioning accuracy of the cover plate are further improved, ensuring that the fiberglass cover plate 4 will not shift or shake after installation.

[0034] In this embodiment, a rubber sleeve 10 is provided on the side of the vertical beam 92. The surface of the rubber sleeve 10 is arc-shaped and elastic. When installing the fiberglass cover plate 4, the arc-shaped design can reduce the friction between the cover plate and the vertical beam 92, so that the cover plate can be installed more smoothly. At the same time, the elastic rubber sleeve 10 can compensate for minor errors in the installation process and fit tightly against the side wall of the fiberglass cover plate 4.

[0035] The working principle of this utility model is as follows: The waste gas collection device for the water treatment tank includes a treatment tank body 1, which is divided into several treatment areas 3 by partitions 2.

A branch pipe 6 is provided at the through hole 5, and the end of the branch pipe 6 is connected to a main pipe 7. The main pipe 7 is connected to a VOCs negative pressure collection device 11 through an exhaust device 8. When using this device, the exhaust device 8 generates negative pressure after starting. Under the action of negative pressure, the waste gas in each treatment area 3 enters the branch pipe 6 through the through hole 5 of the fiberglass cover plate 4, and is then transported to the VOCs negative pressure collection device 11 through the main pipe 7, thereby completing the process of waste gas collection and transmission. This realizes the active collection of waste gas in the water treatment tank, changing the passive method of simply covering the tank and relying on natural diffusion. It improves the waste gas collection efficiency, effectively prevents the odor problem caused by long-term accumulation of waste gas, greatly reduces the odor in the workshop, and improves the working environment.

[0036] When installing the fiberglass cover plate 4, a T-shaped beam 9 is provided at the upper end of the partition plate 2. The T-shaped beam 9 abuts against the fiberglass cover plate 4. The T-shaped beam 9 enhances the stability of the fiberglass cover plate 4 installation, allowing the fiberglass cover plate 4 to be stably installed above the processing area 3. It also helps to improve the sealing between the fiberglass cover plate 4 and the partition plate 2. The T-shaped beam 9 includes a horizontal beam 91 and a vertical beam 92. The side end face of the vertical beam 92 abuts against the side wall of the fiberglass cover plate 4, and the lower end face of the horizontal beam 91 abuts against the upper end face of the fiberglass cover plate 4. Through the multi-faceted contact between the horizontal beam 91 and the vertical beam 92 and the fiberglass cover plate 4, the support force and positioning accuracy of the cover plate are further improved, ensuring that the fiberglass cover plate 4 will not shift or shake after installation.
