Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment equipment, and particularly relates to energy-saving devices and waste gas treatment systems used in waste gas treatment equipment. Background Technology

[0002] Industrial production generates a large amount of waste gas. This waste gas contains a variety of harmful substances, and if it is discharged directly without treatment, it will cause serious environmental pollution, affect the balance of the ecosystem, and destroy biodiversity. In addition, harmful substances in waste gas may enter the human body through inhalation, skin contact, or the food chain, leading to various health problems.

[0003] In existing technologies, waste gas treatment equipment is usually used to treat waste gas. However, traditional waste gas treatment equipment cannot adjust its frequency, time, air intake and other parameters according to the content of the gas to be treated in the waste gas, resulting in high energy consumption.

[0004] To achieve energy conservation, the first approach is to upgrade the waste gas treatment equipment by replacing the product. However, this requires discarding the waste gas treatment equipment that is still in normal working order, and traditional waste gas treatment equipment cannot be fully utilized. The second approach is to upgrade the traditional waste gas treatment equipment through modification. However, equipment modification requires a long period of downtime for rectification, which seriously delays production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an energy-saving device and a waste gas treatment system for waste gas treatment equipment, which can carry out energy-saving transformation of traditional waste gas treatment equipment without the need for long-term shutdown for rectification.

[0006] The technical solution proposed by this utility model is as follows:

[0007] In a first aspect, this utility model provides an energy-saving device for waste gas treatment equipment, comprising:

[0008] Box;

[0009] Concentration detector, which is installed inside the enclosure;

[0010] The first pipe has one end connected to the input end of the concentration detector, and the other end extends out of the box and is connected to the connecting pipe.

[0011] The controller, located inside the housing, is used to control the opening, closing, and adjustment of various components. Data detected by the concentration detector is transmitted to the controller, which then transmits the detected concentration data to the control system of the waste gas treatment equipment. The control system of the waste gas treatment equipment then adjusts the waste gas treatment equipment.

[0012] Optionally, the medium transported in the connecting pipeline is gas, and the waste gas treatment equipment treats waste gas.

[0013] Optional, also includes:

[0014] The first working pump is installed on the first pipeline and located inside the housing. The first working pump is connected to the controller.

[0019] Optionally, the filtration assembly includes at least one particulate filter.

[0020] Optionally, the filtration assembly further includes a condenser disposed between the particulate filter and the flow meter, the condenser being connected to the controller.

[0021] Optional, also includes:

[0022] The second working pump is used to discharge impurities generated by the particulate filter and moisture generated by the condenser. The second working pump is connected to the controller.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention, by incorporating a concentration detection device and a controller within the housing, enables the rapid integration of an energy-saving device with traditional waste gas treatment equipment.

[0033] Example 1

[0034] Please refer to Figure 1-2 This utility model provides an energy-saving device for waste gas treatment equipment. This energy-saving device can be used for upgrading and retrofitting waste gas treatment equipment. When in use, the first pipe 12 is connected to the connecting pipe 2 of the waste gas treatment equipment, and the controller 13 is connected to the waste gas treatment equipment 3 wirelessly or wiredly, thus completing the installation of this utility model.

[0035] refer to Figure 1 The energy-saving device includes a housing 1, which is a hollow structure. Inside the housing 1 are a concentration detector 11 and a controller 13. The input end of the concentration detector 11 is connected to a first pipe 12. The other end of the first pipe 12 extends out of the housing 1 and is connected to a connecting pipe 2, so that the waste fluid can flow into the concentration detector 11 from the connecting pipe 2 through the first pipe 12. The data of the concentration detector 11 is transmitted to the controller 13 in real time, and then the controller 13 adjusts the waste gas treatment equipment 3.

[0036] It should be noted that, in specific use, the first pipe 12 can be disassembled into two sections, one of which is located inside the box 1 and the other is located outside the box 1. The two pipe sections are connected by a connector (the connector is fixedly installed on the box 1). The first pipe 12 can also be telescopic. When in use, pull the first pipe 12 to extend it out of the box. After use, use a winch or torsion spring to retract the first pipe 12 into the box 1.

[0037] It should be noted that casters can be further installed at the bottom of the box 1 to improve the flexibility of the box 1 when moving.

[0038] It should be noted that data transmission between the controller 13 and the concentration detector 11 can be achieved via wired or wireless means as needed.

[0039] It should be noted that the controller 13 can be any one of a PLC controller 13, a CNC controller 13, or a PID controller 13. In specific operation, the controller 13 transmits the detected concentration data to the control system of the waste treatment equipment 3. When the concentration is below a threshold, the control system of the waste treatment equipment 3 adjusts the waste treatment equipment 3, reducing its power; when the concentration is above a threshold, the control system of the waste treatment equipment 3 adjusts the waste treatment equipment 3, increasing its power. (Obviously, multiple thresholds can be set, and the control of the waste treatment equipment 3 can be configured.) The control system can turn the waste gas treatment equipment 3 on or off according to specific circumstances, or adjust the air intake of the waste gas treatment equipment 3. The controller 13 can transmit data to the control system of the waste gas treatment equipment 3 wirelessly or via wired means. The waste gas treatment equipment 3 is an existing device on the market. The control system of the waste gas treatment equipment 3 is a built-in system of the waste gas treatment equipment 3 and is not within the scope of protection of this application. It is only necessary to connect the existing waste gas treatment equipment 3 to the energy-saving device of this application through a pipeline to transport waste gas. The controller of the energy-saving device of this application and the control system of the waste gas treatment equipment 3 can transmit data.

[0040] As a preferred embodiment, a first working pump 14 is installed inside the housing 1. The first working pump 14 is installed on the first pipeline 12. The first working pump 14 can quickly transport the fluid in the connecting pipeline 2 to the concentration detector 11.

[0041] As a preferred embodiment, a filter assembly 15 is installed inside the housing 1 to filter the fluid and prevent other impurities from interfering with the detection results of the concentration detector 11.

[0042] As a preferred option, a flow meter 16 is installed inside the housing 1 to regulate the flow rate of the fluid entering the concentration detector 11, thereby ensuring the consistency of the detection results.

[0043] Example 2

[0044] refer to Figure 1The working principle of this utility model is as follows (taking VOC gas as an example, the waste gas treated by the waste gas treatment device 3): The first working pump 14 transports the waste gas from the connecting pipe 2 to the housing 1. The waste gas passes through the particulate filter 151 to filter dust and particulate matter, then through the condenser 152 to remove moisture. After the flow rate of the waste gas is adjusted by the flow meter 16, it enters the VOC concentration detector 11 to detect the VOC gas concentration. The detected data is transmitted to the controller 13, which transmits the concentration detection result to the control system of the waste gas treatment device 3. This adjusts the processing capacity of the waste gas treatment device 3, for example, by adjusting parameters such as processing time, frequency, and air intake volume based on the VOC gas concentration, thereby achieving energy saving. The energy-saving device of this utility model is independent of the waste gas treatment device, but can be used in conjunction with it, offering flexible operation and easy maintenance.

[0045] It should be noted that one or more particulate filters 151 can be used in this embodiment. Preferably, two particulate filters 151 are connected in series to form a two-stage filtration system, which can more effectively remove impurities. The particulate filter 151 in this embodiment can adopt various schemes, such as mechanical filters, electrostatic filters, wet filters, composite filters, granular layer filters, etc., preferably CEMS flue gas filters (the filter element material of this filter can be ceramic, PTFE, glass fiber, etc., selected according to the type of exhaust gas being detected).

[0046] It should be noted that in this solution, the condenser 152 is placed after the particulate filter 151 to prevent dust and particulate matter from entering the condenser 152, adhering to the condenser tube wall, affecting the condensation effect, and making later maintenance inconvenient.

[0047] It should be noted that the first working pump 14 in the above embodiment is an air pump.

[0048] It should be noted that, in the above embodiment, impurities generated by the particulate filter 151 can be discharged outside the housing 1 via the second working pump 17; moisture generated in the condenser 152 can also be discharged outside the housing 1 via the second working pump 17. Specifically, the second working pump 17 can be a peristaltic pump.

[0049] It should be noted that valves can be installed on the pipelines between the above-mentioned components.

[0050] It should be noted that VOCs are an abbreviation for Volatile Organic Compounds, which are organic compounds that can volatilize into a gaseous state under certain conditions. VOCs are a significant source of air pollution, posing potential risks to the environment and human health. VOCs include various compounds such as benzene, formaldehyde, and xylene.

[0051] It should be noted that the VOC waste gas treatment equipment in the above embodiments can be existing technologies such as regenerative thermal oxidizers (RTO), adsorption-desorption catalytic combustion equipment, concentrated zeolite rotor + regenerative thermal oxidizer / catalytic combustion equipment (RTO / RCO), condensation purification equipment, catalytic combustion equipment, and VOCs treatment equipment using a combination of condensation and pressure swing adsorption.

[0052] It should be noted that the above embodiments only take VOC gas as an example, and can also be used in other types of waste gas treatment systems and wastewater treatment systems; the appropriate concentration detector 11 and filter assembly 15 can be selected according to the specific type of fluid being treated.

[0053] Example 3

[0054] This utility model also protects an exhaust gas treatment system, which includes the energy-saving device for exhaust gas treatment equipment described in the above embodiments.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
