Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically a waste gas buffer and collection device. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, and chemical waste gas purification. In the process of waste gas treatment, there is the issue of buffering and collecting waste gas.

[0003] In the existing technology, conventional exhaust gas buffer collection devices simply collect exhaust gas through gas tanks. They have a single function and cannot adjust the exhaust gas pressure according to the exhaust gas usage requirements. At the same time, during the exhaust gas collection process, the precipitated impurities in the exhaust gas accumulate inside the buffer collection device. With long-term use, a large amount of impurities will settle, affecting the normal use of the exhaust gas buffer collection device. Utility Model Content

[0004] This invention provides an exhaust gas buffer and collection device to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas buffer collection device, comprising a tank, a connecting pipe fixedly installed on the upper surface of the tank by a fixing rod, the lower left side of the connecting pipe being connected to the tank by a first extraction mechanism, and the upper right side of the tank being connected to the connecting pipe by a second extraction mechanism, both the first and second extraction mechanisms being installed on the upper surface of the tank, a first air pressure sensor being provided on the connecting pipe near the right edge, a one-way air inlet valve, a reminder mechanism, and a safety valve being installed sequentially from left to right on the middle of the upper sidewall of the tank, a guide bucket being fixedly installed on the inner wall of the tank near the lower side, and a slag discharge mechanism being fixedly installed on the lower surface of the guide bucket, the slag discharge mechanism being installed between the left and right sidewalls of the tank.

[0006] Furthermore, the first extraction mechanism includes a fan, a duct, and an electric flow control valve. The fan is fixedly installed on the upper surface of the tank. The inlet and outlet of the fan are connected to the tank and the connecting pipe through the duct, respectively. The electric flow control valve is installed on the duct.

[0007] Furthermore, the second extraction mechanism has the same structure as the first extraction mechanism.

[0008] Furthermore, the reminder mechanism includes a controller, a second pressure sensor, and an alarm. The controller is installed on the upper surface of the tank, and the second pressure sensor is embedded in the upper side wall of the tank corresponding to the controller. The alarm is fixedly installed on the upper surface of the controller.

[0009] Furthermore, the controller is electrically connected to the first extraction mechanism, the second extraction mechanism, the first air pressure sensor, and the slag discharge mechanism, respectively.

[0010] Furthermore, the slag discharge mechanism includes a cylinder, a motor, a screw feeder, and a sealing cover. The cylinder is fixedly installed on the left and right side walls of the tank, and the upper surface of the cylinder is connected to the guide bucket. The motor is fixedly installed on the left side of the cylinder, and the screw feeder is fixedly installed on the right side of the output shaft of the motor. The screw feeder is installed inside the cylinder, and the sealing cover is threaded onto the right side of the cylinder.

[0011] Compared with the prior art, the present invention provides an exhaust gas buffer and collection device, which has the following beneficial effects:

[0012] 1. This waste gas buffer collection device uses a first pressure sensor to check the waste gas pressure in the connecting pipe. When the pressure in the waste gas pipeline is too high, the first extraction mechanism draws the waste gas into the tank. When the pressure in the waste gas pipeline is too low, the second extraction mechanism draws the waste gas from the tank into the connecting pipe to replenish the gas, thereby stabilizing the waste gas pressure in the waste gas pipeline and facilitating subsequent waste gas treatment.

[0013] 2. This waste gas buffer collection device, by setting up a slag discharge mechanism, can discharge the impurities that have settled in the tank, effectively preventing excessive accumulation of waste gas in the tank. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 This utility model discloses a waste gas buffer collection device, including a tank 1. A connecting pipe 3 is fixedly installed on the upper surface of the tank 1 by a fixing rod 2. The lower left side of the connecting pipe 3 is connected to the tank 1 by a first extraction mechanism 4. The upper right side of the tank 1 is connected to the connecting pipe 3 by a second extraction mechanism 5. Both the first extraction mechanism 4 and the second extraction mechanism 5 are installed on the upper surface of the tank 1. A first air pressure sensor 6 is provided on the connecting pipe 3 near the right edge. A one-way air inlet valve 7, a reminder mechanism 8 and a safety valve 9 are installed sequentially from left to right on the middle of the upper side wall of the tank 1. A guide bucket 10 is fixedly installed on the inner wall of the tank 1 near the lower side, and a slag discharge mechanism 11 is fixedly installed on the lower surface of the guide bucket 10. The slag discharge mechanism 11 is installed between the left and right side walls of the tank 1.

[0020] Specifically, the first extraction mechanism 4 includes a fan 401, a conduit 402, and an electric flow control valve 403. The fan 401 is fixedly installed on the upper surface of the tank 1. The inlet and outlet of the fan 401 are connected to the tank 1 and the connecting pipe 3 through the conduit 402, respectively. The electric flow control valve 403 is provided on the conduit 402.

[0021] In this embodiment, the fan 401 draws the exhaust gas in the connecting pipe 3 into the tank 1 through the conduit 402, and the flow rate of the exhaust gas entering the tank 1 is adjusted by the electric flow control valve 403 to achieve the effect of depressurizing the exhaust gas in the connecting pipe 3, that is, to buffer and collect the exhaust gas.

[0022] Specifically, the second extraction mechanism 5 has the same structure as the first extraction mechanism 4.

[0023] In this embodiment, the second extraction mechanism 5 extracts the exhaust gas in the tank 1 into the connecting pipe 3, increasing the gas pressure of the exhaust gas in the connecting pipe 3 and ensuring that the gas pressure of the exhaust gas in the connecting pipe 3 is stable.

[0024] Specifically, the reminder mechanism 8 includes a controller 801, a second pressure sensor 802, and an alarm 803. The controller 801 is installed on the upper surface of the tank 1, and the second pressure sensor 802 is embedded in the upper side wall of the tank 1 corresponding to the controller 801. The alarm 803 is fixedly installed on the upper surface of the controller 801.

[0025] In this embodiment, the second pressure sensor 802 monitors the pressure inside the tank 1. When the pressure inside the tank 1 is greater than the set value, the information is fed back to the controller 801. The controller 801 then triggers the alarm 803 and stops injecting gas into the tank 1.

[0026] Specifically, the controller 801 is electrically connected to the first extraction mechanism 4, the second extraction mechanism 5, the first air pressure sensor 6, and the slag discharge mechanism 11, respectively.

[0027] In this embodiment, the controller 801 can control the first extraction mechanism 4, the second extraction mechanism 5, the first air pressure sensor 6, and the slag discharge mechanism 11.

[0028] Specifically, the slag discharge mechanism 11 includes a cylinder 111, a motor 112, a screw feeder 113, and a sealing cover 114. The cylinder 111 is fixedly installed on the left and right side walls of the tank body 1, and the upper surface of the cylinder 111 is connected to the guide bucket 10. The motor 112 is fixedly installed on the left side of the cylinder 111, and the screw feeder 113 is fixedly installed on the right side of the output shaft of the motor 112. The screw feeder 113 is installed inside the cylinder 111, and the sealing cover 114 is threaded onto the right side of the cylinder 111.

[0029] In this embodiment, the impurities precipitated in the guide bucket 10 fall into the cylinder 111. The output shaft of the motor 112 drives the screw feed rod 113 to rotate, opening the sealing cover 114, so that the screw feed rod 113 discharges the precipitated impurities from the tank 1. This needs to be done when there is no buffered waste gas in the tank 1.

[0030] In use, the left and right ends of the connecting pipe 3 are connected to the exhaust gas pipeline via flanges. The first pressure sensor 6 monitors the exhaust gas pressure inside the connecting pipe 3. When the exhaust gas pressure inside the connecting pipe 3 exceeds a set value, the information is fed back to the controller 801. The controller 801 then opens the fan 401 and the electric flow control valve 403 in the first extraction mechanism 4. The fan 401 draws the exhaust gas from the connecting pipe 3 into the tank 1 through the conduit 402. The electric flow control valve 403 regulates the flow rate of the exhaust gas entering the tank 1, thereby achieving the effect of depressurizing the exhaust gas inside the connecting pipe 3. The system buffers and collects waste gas. When the waste gas pressure in the connecting pipe 3 is less than the set value, the second extraction mechanism 5 draws the waste gas from the tank 1 into the connecting pipe 3 to replenish the gas, thereby stabilizing the waste gas pressure in the connecting pipe 3 and facilitating subsequent waste gas treatment. When there is no waste gas in the tank 1, the impurities precipitated in the guide bucket 10 fall into the cylinder 111 in the slag discharge mechanism 11. The output shaft of the motor 112 drives the screw feed rod 113 to rotate, opening the sealing cover 114 and allowing the screw feed rod 113 to discharge the precipitated impurities from the tank 1, effectively preventing excessive impurities in the tank 1 from affecting its use.

[0031] In summary, this waste gas buffering and collection device buffers and collects waste gas when the gas pressure in the waste gas pipeline is too high, and replenishes the gas with higher pressure when the gas pressure is too low, so as to stabilize the gas pressure in the waste gas pipeline, which is beneficial for subsequent waste gas treatment. It can also buffer the waste gas to discharge the generated impurities, which is beneficial for use.
