Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, and in particular to a production waste gas homogenization and conditioning system. Background Technology

[0002] Homogeneous combustion is an orderly combustion process in which fuel and oxidant are completely and uniformly mixed. Its combustion characteristics are highly consistent, making it an ideal combustion mode in the field of internal combustion engine technology. This technology improves combustion efficiency and engine power by optimizing the air-fuel mixture ratio, and significantly reduces the content of exhaust pollutants.

[0003] The production waste gas homogenization and conditioning system requires the use of a mixing tank during the waste gas treatment process. The waste gas is injected into the mixing tank through pipelines for treatment.

[0004] Directly introducing exhaust gas into the mixing tank can easily cause concentration stratification, and sudden changes in exhaust gas concentration often lead to drastic fluctuations in FTA values, potentially causing RTO shutdown, reducing RTO lifespan, and causing a series of environmental problems. Pressure shocks and sudden flow changes can cause mixing tank inlet pressure fluctuations exceeding ±300Pa, accelerating valve wear and heat storage cracking, and wasting energy. To cope with these fluctuations, the fan often operates at rated power, increasing annual energy consumption by 15%–20%.

[0005] Therefore, it is necessary to provide a production waste gas homogenization and conditioning system to solve the above-mentioned technical problems. Utility Model Content

The production waste gas homogenization and conditioning system includes: a mounting base 1;

[0033] A static mixer 8 is installed on the top of the mounting base 1 near one side. The static mixer 8 has an exhaust gas inlet pipe 7 installed at its inlet and a U-shaped pipe 3 installed at its outlet. A Y-type filter 9 is installed on the top of the mounting base 1 near the middle. A first valve 2 is installed at the outlet of the Y-type filter 9.

A mixing frame 14 is installed at the output end of the drive assembly 11 via a rotating shaft 15.

[0034] A variable frequency fan 12 is installed on the top of the mounting base 1. The inlet of the variable frequency fan 12 is equipped with a connecting pipe 18, and the outlet of the variable frequency fan 12 is equipped with an injection pipe 17.

[0035] The other end of the U-shaped pipe 3 is connected to the inlet of the Y-type filter 9, and the other end of the connecting pipe 10 is connected to the inlet of the buffer tank 13. A valve is installed at the connection between the connecting pipe 18 and the buffer tank 13 to achieve sealing and pressurization. The other end of the injection pipe 17 is connected to the mixing tank 16, and the mixing rack 14 can break up the waste.

[0036] The mounting base 1 includes a base plate 101, a mounting structure 102 and an adjustment structure 103. The mounting structure 102 is used to mount the adjustment structure 103 on the bottom of the base plate 101. A control box 4 with a door 5 and an operation panel 6 is mounted on the top of the mounting base 1.

[0037] The threaded connection between the mounting structure 102 and the adjustment structure 103 facilitates the adjustment of the flatness of the base plate 101. The door 5 is equipped with a lock. The control box 4 contains a power switch and a controller for controlling the operation of the equipment. The operation panel 6 can be used to set the equipment operation controller.

[0038] The drive assembly 11 includes a protective shell 111, an angle sensor 112, and a drive component 113. The protective shell 111 is used to install the drive component 113, which provides rotational driving force to the rotating shaft 15.

[0041] The static mixer 8, Y-type filter 9, buffer tank 13, and mixing tank 16 are installed on top of the mounting base 1. The Y-type filter 9 and the static mixer 8 are connected through the U-shaped pipe 3, and the Y-type filter 9 and the buffer tank 13 are connected through the connecting pipe 10 with the first valve 2. The inlet and outlet of the variable frequency fan 12 are connected to the buffer tank 13 and the mixing tank 16 through the connecting pipe 18 and the injection pipe 17. In actual use, the exhaust gas enters the static mixer 8 through the exhaust gas inlet pipe 7 for forced homogenization and then passes through the U-shaped pipe 3 for energy buffering. The exhaust gas discharged from the U-shaped pipe 3 enters the buffer tank 13 through the connecting pipe 10 for secondary homogenization and pressure stabilization. At the same time, the variable frequency fan 12 dynamically adjusts the delivery pressure, and the intelligent module analyzes the data in real time to simultaneously optimize the mixing intensity, buffering time, and fan speed. In abnormal operating conditions, such as when the VOC concentration exceeds the limit, the emergency bypass is activated and the RTO combustion system is linked. Finally, the exhaust gas is injected into the interior of the mixing tank 16.

[0042] Compared with related technologies, the production waste gas homogenization and conditioning system provided by this utility model has the following beneficial effects:

[0043] To ensure the stability and safety of the production exhaust gas homogenization and conditioning system, a static mixer 8, a Y-type filter 9, a buffer tank 13, and a mixing tank 16 are installed on top of the mounting base 1. The Y-type filter 9 and the static mixer 8 are connected via a U-shaped pipe 3, and the Y-type filter 9 and the buffer tank 13 are connected via a connecting pipe 10 with a first valve 2. The inlet and outlet of the variable frequency fan 12 are connected to the buffer tank 13 and the mixing tank 16 via a connecting pipe 18 and an injection pipe 17. This design, through structural synergistic optimization, intelligent control algorithms, and safety redundancy design, systematically solves the problems of high fluctuation, high energy consumption, and high risk in traditional RTO systems. Its core advantages are: dual stability of concentration and pressure (±5% concentration fluctuation, ±50Pa pressure fluctuation), dual reduction in energy consumption and maintenance costs (energy saving of 30%–45%, maintenance cost reduction of 40%–60%), dual improvement in safety and adaptability (explosion venting protection, multi-scenario adaptation).

[0044] Second Embodiment

[0045] Please refer to the following: Figures 4-5 , Figure 4 A schematic diagram of the structure of the second embodiment of the production waste gas homogenization and conditioning system provided by this utility model; Figure 5 This utility model provides a structural schematic diagram of a booster device. Based on the production waste gas homogenization and conditioning system provided in the first embodiment of this application, the second embodiment of this application proposes another production waste gas homogenization and conditioning system. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference in the production exhaust gas homogenization and conditioning system provided in the second embodiment of this application is that a booster device 24 is installed on the top of the mounting base 1, and a booster pipe 19 is installed at the outlet of the booster device 24;

[0047] The other end of the booster pipe 19 is connected to the second valve 20. The booster device 24, which includes a housing and a booster pump, can boost the pressure of the buffer tank 13.

[0048] A fixed base 22 is installed on the top of the buffer tank 13, and a pressure monitoring device 21 is installed on the top of the fixed base 22;

[0049] The pressure monitoring device 21 can monitor the pressure changes inside the buffer tank 13, and can balance the pressure when used in conjunction with the pressurization device 24.

[0050] A pressure relief valve 23 is installed on the top of the buffer tank 13, and a second valve 20 is installed on the top of the buffer tank 13.

[0051] The pressure relief valve 23 can open automatically when pressure needs to be released, so as to release excess pressure from the buffer tank 13.

[0052] Compared with related technologies, the production waste gas homogenization and conditioning system provided by this utility model has the following beneficial effects:

[0053] In order to balance the pressure changes inside the buffer tank 13, an electrically controlled pressure relief valve 23 is installed on the top of the buffer tank 13. When pressure relief is needed, the pressure relief valve 23 opens to balance the pressure. When the internal pressure of the buffer tank 13 is low, the pressurization device 24 is started and the second valve 20 is opened to pressurize the buffer tank 13. This design uses pressure to buffer the exhaust gas in the buffer tank 13, thereby improving the safety of the production exhaust gas homogenization and conditioning system.
