Description

Technical Field

[0001] The present application relates to the field of tail gas absorption, and in particular to a glass fiber reinforced plastic chlorine absorption system. Background Art

[0002] In current industrial production, chlorine is an important and widely used raw material, used in the manufacture of chemicals, plastics, pharmaceuticals and other industries. However, despite the important role chlorine plays in industrial production, its emission is a serious environmental and health problem. Chlorine emissions not only pollute the atmosphere, but also form ozone and chloramines, which in turn cause acid rain and photochemical smog, causing serious damage to the environment. In addition, long-term exposure to chlorine can also cause harm to human health, including respiratory irritation, lung damage, and damage to the nervous system.

[0003] In order to effectively control chlorine emissions, a single absorption tower is currently often used for chlorine absorption treatment. However, this traditional treatment method has some obvious limitations. First, a single absorption tower can only absorb once. When the chlorine content in the airflow is high, it is difficult to completely absorb the chlorine due to limited reaction time, resulting in excessive residual chlorine emissions. Secondly, although simply increasing the number of absorption towers can improve absorption efficiency, it will cause a waste of equipment resources, increase investment and operating costs, and does not meet the requirements of resource conservation and sustainable development.

[0004] Therefore, in order to solve the problems existing in the traditional single absorption tower treatment method, a new technology is needed to improve the chlorine absorption efficiency, reduce resource waste, and be able to flexibly respond to changes in different chlorine contents and process requirements. Utility Model Content

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a fiberglass reinforced plastic chlorine absorption system that can intelligently adjust the system working mode according to changes in chlorine content, thereby improving resource utilization efficiency and ensuring absorption efficiency and emission compliance.

[0006] To achieve the above-mentioned purpose, the present application discloses a glass fiber reinforced plastic chlorine absorption system, comprising a primary absorption tower, a secondary absorption tower and a controller, wherein the primary absorption tower is provided with a first air intake port and a first air exhaust port, the first air intake port is connected to an air intake pipe, and the air intake pipe is used to access the airflow of chlorine to be absorbed; a chlorine detection device connected to the controller is installed in the air intake pipe, and the chlorine detection device is used to detect the chlorine content in the airflow and send the data to the controller; the first exhaust port of the primary absorption tower is connected to the secondary absorption tower / exhaust pipe via a diverter component; the secondary absorption tower has a second air intake port connected to the diverter component and a second exhaust port connected to the exhaust pipe.

[0007] Further, the diversion component consists of a first pipeline, a second pipeline, a third pipeline and an electrically controlled three-way valve.

[0008] Furthermore, a second exhaust fan is provided in the second pipeline, and the second exhaust fan accelerates the airflow in the second pipeline and sends it to the exhaust pipe.

[0009] Furthermore, the exhaust pipe is connected to the first exhaust fan, and the first exhaust fan accelerates the airflow sent out from the second exhaust port of the secondary absorption tower and sends it to the exhaust pipe.

[0010] Furthermore, the first-stage absorption tower has the same structure as the second-stage absorption tower, and is composed of a fiberglass tank and a lower spray assembly, a lower filler, an upper spray assembly, an upper filler and a demister located inside the fiberglass tank. A flow valve controlled by a controller is each provided at the liquid inlet of the first spray assembly and the second spray assembly.

[0011] Furthermore, the demister is arranged near the exhaust end, and the airflow is sent to the glass fiber reinforced plastic tank after being demistered by the demister; the demister has an inlet, and the edge of the inlet is serrated.

[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0013] 1. You can flexibly choose primary or secondary absorption according to the different chlorine content to maximize the absorption efficiency. When the chlorine content in the airflow is low, you can choose primary absorption to reduce energy consumption and cost; when the chlorine content in the airflow is high, you can switch to secondary absorption to ensure complete absorption of chlorine.

[0014] 2. The edge of the demister inlet is serrated, which can further enhance the demisting effect and prevent the spray liquid from being entrained and discharged.

[0023] like Figure 1 and Figure 2 As shown, this embodiment discloses an exemplary structure of a glass fiber reinforced plastic chlorine absorption system, including a primary absorption tower 1, a secondary absorption tower 2 and a controller 3. The system is used for absorbing and purifying chlorine in industrial exhaust gas, and is intended to provide an efficient, flexible and stable chlorine treatment solution to meet the requirements of different chlorine emission concentrations and environmental protection standards.

[0024] Structurally, the primary absorption tower 1 is specifically used for primary chlorine absorption. The primary absorption tower 1 is composed of a glass fiber reinforced plastic tank 4, a spray assembly, a filler and a demister 5. As the main body of the primary absorption tower 1, the glass fiber reinforced plastic tank 4 has the characteristics of light weight, high strength and corrosion resistance, and can operate stably in a corrosive environment for a long time. The selection of glass fiber reinforced plastic material is based on its excellent corrosion resistance, which can effectively resist the erosion of corrosive media such as chlorine, thereby extending the service life of the system.

[0025] Two spray assemblies are arranged inside the tank body, which are respectively located at the upper and lower parts of the tank body, forming an upper spray assembly 6 and a lower spray assembly 7. The upper spray assembly 6 and the lower spray assembly 7 cooperate with the upper filler 8 and the lower filler 9 to contact and absorb the chlorine gas with the absorbent. The lower spray assembly 7 is located at the bottom of the tank and is composed of a plurality of nozzles, which are used to spray the absorbent evenly onto the lower filler 9. The lower filler 9 usually adopts a three-dimensional mesh structure with a large surface area, which is conducive to increasing the gas-liquid contact area and improving the chlorine absorption efficiency. The material selection of the lower filler 9 has good compatibility with the properties of the absorbent and the working environment to ensure that the absorbent can fully contact with the chlorine gas and effectively absorb it.

[0026] Corresponding to the lower spray assembly 7 are the upper spray assembly 6 and the upper filler 8, which are located at the top of the tank. The upper spray assembly 6 is similar to the lower spray assembly 7 and is responsible for spraying the absorbent to the upper filler 8. The upper filler 8 is also designed to increase the gas-liquid contact area and usually adopts a structure with the same high surface area characteristics.

[0027] A demister 5 is provided at the upper part of the primary absorption tower 1 to remove liquid droplets in the exhaust gas and ensure the cleanliness of the exhaust gas. The design of the demister 5 takes into account the problem of liquid droplets that may be carried out in the airflow, and adopts a sawtooth inlet 12 design, which can effectively remove liquid droplets in the airflow and ensure the dryness and cleanliness of the exhaust gas.

[0028] The controller 3 is the control core of the system and is responsible for monitoring, controlling and adjusting the operating status of the system. The operation of the controller 3 is based on the chlorine detection device 15, which is installed in the air inlet pipe 11 and can monitor the chlorine content in the air flow in real time and transmit the detection data to the controller 3. The controller 3 automatically adjusts the working parameters of the spray assembly, such as the spraying amount of the nozzle, according to the detected chlorine content data to ensure that the spraying amount of the absorbent can adapt to the current gas situation. The controller 3 can also adjust the operating status of the primary and secondary absorption towers as needed to ensure the optimal absorption efficiency and resource utilization of the system.

[0029] The system is also equipped with a secondary absorption tower 2, which has a similar structure and function to the primary absorption tower 1, as a second line of defense for supplementary absorption of chlorine. The design of the secondary absorption tower 2 is the same as that of the primary absorption tower 1. When necessary, it is used to further absorb the residual chlorine in the gas flow to ensure that the emission gas meets the standards.

[0030] In order to achieve flexible switching between primary absorption and secondary absorption, the exhaust port of the primary absorption tower 1 is connected to a diversion assembly 10. The diversion assembly 10 consists of a first pipeline, a second pipeline, a third pipeline and an electrically controlled three-way valve. The first pipeline is connected to the exhaust port of the primary absorption tower 1, the second pipeline is connected to the exhaust pipe 12, and the third pipeline is connected to the air inlet of the secondary absorption tower 2. The electrically controlled three-way valve is controlled by a controller 3, and the airflow is directed to the secondary absorption tower 2 or directly discharged through the exhaust pipe 12 according to the chlorine content and system requirements.

[0031] The system is provided with a first exhaust fan 13 in the exhaust pipe 12, which is used to accelerate gas exhaust and ensure stable operation of the system. The airflow discharged from the secondary absorption tower 2 is accelerated and sent to the exhaust pipe 12. The second exhaust fan 14 is located in the second pipeline of the diversion component 10. Under the operating condition of the primary absorption, the airflow from the primary absorption tower 1 is accelerated and discharged, further ensuring smooth exhaust of the system.

[0032] The entire glass fiber reinforced plastic chlorine absorption system of this embodiment has a reasonable structure and precise design, and can flexibly adjust the primary or secondary absorption efficiency according to the chlorine concentration, achieve efficient and stable chlorine absorption, and adapt to different emission standards and environmental protection requirements. The intelligent control of the controller ensures the stable operation of the system and the optimal use of resources, effectively reducing energy consumption and maintenance costs.

[0033] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
