The water is atomized and sprayed out to wash the waste gas generated in petroleum refining, thereby reducing the amount of waste gas pollution.

[0004] In traditional petroleum refining waste gas treatment devices, insufficient contact between waste gas and treatment liquid leads to low waste gas purification efficiency. When adding reagents manually to the treatment liquid, there are problems such as inaccurate dosage control and uneven mixing of reagents and treatment liquid. Utility Model Content

[0005] The purpose of this invention is to provide a pollution-proof waste gas treatment device for petroleum refining, in order to solve the problem in the above-mentioned background technology that the waste gas and the treatment liquid do not come into sufficient contact, resulting in low waste gas purification efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pollution-proof waste gas treatment device for petroleum refining, comprising a spray tower and a treatment tank, wherein the spray tower and the treatment tank are interconnected by pipelines; A liquid delivery pipe is fixedly connected to the middle of the lower end of the spray tower and the middle of the lower end of the treatment tank. A water pump is installed in the middle of the liquid delivery pipe. A fixed sleeve is fixedly connected to the top of the treatment tank. An air guide pipe is installed inside the fixed sleeve.

A pressurizing pipe is fixedly connected to the input end of the air pump. The pressurizing pipe has a conical structure and completely covers the end face of the air outlet pipe of the spray tower.

[0008] Preferably, the fixed sleeve has equidistantly distributed exhaust grooves at the bend, and the fixed sleeve, which forms a vertical structure on the top of the treatment tank, together with the exhaust grooves, constitutes an exhaust pipe.

[0009] Preferably, a drain pipe is fixedly connected to one side of the inside of the treatment tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This pollution-preventing waste gas treatment device for petroleum refining uses a diversion pipe installed on the outer side of the bottom of the gas guide pipe and equidistantly distributed jet nozzles arranged on the top of the diversion pipe. Combined with the gas guide pipe extending to the bottom of the treatment tank, the waste gas transported through the gas guide pipe can be evenly dispersed into the treatment liquid in the treatment tank through the jet nozzles.

[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] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution: like Figure 1 As shown, a pollution-preventable waste gas treatment device for petroleum refining includes a spray tower 1 and a treatment tank 2, which are interconnected by pipelines; Figure 2 , Figure 3 and Figure 6As shown, a liquid delivery pipe 3 is fixedly connected to the middle of the lower end of the spray tower 1 and the middle of the lower end of the treatment tank 2. A water pump 4 is installed in the middle of the liquid delivery pipe 3. A fixing sleeve 5 is fixedly connected to the top of the treatment tank 2. An air guide pipe 6 is installed inside the fixing sleeve 5. The air guide pipe 6 extends to the inside of the treatment tank 2 near the bottom. A diversion pipe 7 is fixedly connected to the outer side of the bottom of the air guide pipe 6 through a pipe. The top of the diversion pipe 7 is provided with equally spaced jet nozzles 8.

[0020] like Figure 5 As shown, the fixed sleeve 5 is connected to the air outlet pipe at the upper end of the spray tower 1. The end of the air guide pipe 6 away from the diversion pipe 7 is fixedly connected to the air pump 9. The input end of the air pump 9 is fixedly connected to the pressurizing pipe 10. The pressurizing pipe 10 has a conical structure and completely covers the end face of the air outlet pipe of the spray tower 1.

[0021] When using this pollution-preventing waste gas treatment device for petroleum refining, the waste gas generated from petroleum refining first enters the interior of the spray tower 1. The spray tower 1 is pre-stored with a treatment liquid for preliminary treatment of the waste gas. The waste gas comes into contact with the treatment liquid in the spray tower 1 to complete the preliminary spray purification and remove some impurities.

[0022] The water pump 4, located in the middle of the infusion pipe 3, is started. After the water pump 4 starts running, it can transport the treatment liquid from the middle of the lower end of the spray tower 1 or the middle of the lower end of the treatment tank 2 to the corresponding tank through the infusion pipe 3 to maintain the normal amount of treatment liquid in the two tanks. The pre-treated waste gas is discharged from the gas outlet pipe at the upper end of the spray tower 1. At this time, the air pump 9, which is fixedly connected to the end of the air guide pipe 6 away from the diversion pipe 7, is started. The air pump 9 draws in waste gas through the pressurization pipe 10, which is fixedly connected to its input end. Since the pressurization pipe 10 has a conical structure and completely covers the end face of the gas outlet pipe of the spray tower 1, it can collect and pressurize the waste gas more efficiently.

[0023] The pressurized exhaust gas enters the air guide pipe 6, which is installed inside the fixed sleeve 5 fixedly connected to the top of the treatment tank 2 and extends to the bottom of the treatment tank 2. The exhaust gas flows downward along the air guide pipe 6 and reaches the diversion pipe 7 fixedly connected to the bottom outside of the air guide pipe 6. Then, it is evenly dispersed into the treatment liquid in the treatment tank 2 through the equally spaced jet nozzles 8 at the top of the diversion pipe 7, so that the exhaust gas and the treatment liquid can come into further contact for subsequent purification treatment.

[0024] Example 2: Based on Example 1, please refer to... Figures 2 to 4 The following structure was also disclosed: like Figure 2As shown, the fixed sleeve 5 has equidistantly distributed exhaust grooves 11 at the bend. The fixed sleeve 5 is part of the vertical structure at the top of the treatment tank 2 and the exhaust grooves 11 together form an exhaust pipe. A drain pipe 12 is fixedly connected to one side inside the treatment tank 2. The drain pipe 12 is connected to the outside and forms a communicating vessel structure with the inside of the treatment tank 2. One end of the drain pipe 12 inside the treatment tank 2 extends to the bottom of the treatment tank 2 and does not contact the bottom of the treatment tank 2.

[0025] like Figure 3 and Figure 4 As shown, a connecting rod 13 is rotatably connected inside the drain pipe 12. A turbine 14 is fixedly connected to the lower end of the connecting rod 13. The upper end of the connecting rod 13 passes through the drain pipe 12 and is fixedly connected to a helical rod 17. A dosing tank 15 is fixedly connected to one side of the top of the treatment tank 2. A drug delivery pipe 16 is fixedly connected to the lower end of the dosing tank 15. The drug delivery pipe 16 extends into the interior of the treatment tank 2. The upper end of the connecting rod 13 and the helical rod 17 are both rotatably connected to the interior of the drug delivery pipe 16.

[0026] The gas purified by the treatment liquid in the treatment tank 2 will flow to the top of the treatment tank 2 and finally be discharged through the equidistantly distributed exhaust grooves 11 provided at the bend of the fixed sleeve 5. The part of the fixed sleeve 5 that is vertical at the top of the treatment tank 2 together with the exhaust grooves 11 forms an exhaust pipe, providing a channel for the discharge of the purified gas.

[0027] The drain pipe 12, which is fixedly connected to one side of the inside of the treatment tank 2, is connected to the outside and forms a communicating vessel structure with the inside of the treatment tank 2. When the amount of treatment liquid in the treatment tank 2 reaches a certain level, the treatment liquid will naturally flow into the drain pipe 12. Since the end of the drain pipe 12 located inside the treatment tank 2 extends to the bottom of the treatment tank 2 and does not contact the bottom of the treatment tank 2, it can be ensured that the treatment liquid in the treatment tank 2 can smoothly enter the drain pipe 12.

[0028] When the treatment fluid flows in the drain pipe 12, it will drive the turbine 14, which is fixedly connected to the lower end of the connecting rod 13 inside the drain pipe 12, to rotate. After the turbine 14 rotates, it will drive the connecting rod 13 to rotate synchronously. The spiral rod 17, which passes through the drain pipe 12 and is fixedly connected to the upper end of the connecting rod 13, will also rotate.

[0029] Meanwhile, the dosing tank 15, which is fixedly connected to the top side of the treatment tank 2, contains the agent for purifying the waste gas. The dosing pipe 16, which is fixedly connected to the lower end of the dosing tank 15, extends into the interior of the treatment tank 2. The upper end of the connecting rod 13 and the screw rod 17 are rotatably connected to the interior of the dosing pipe 16. During the rotation of the screw rod 17, the agent in the dosing tank 15 will be evenly transported to the treatment liquid in the treatment tank 2 along the dosing pipe 16, so that the agent and the treatment liquid are fully mixed, further improving the purification effect on the waste gas.

[0030] Example 3: Based on Examples 1 and 2, please refer to... Figure 2 and Figure 4The following structure was also disclosed: A first water level monitor 18 is fixedly connected to the inner wall of the treatment tank 2. The first water level monitor 18 is located below the outlet of the drain pipe 12. A second water level monitor 19 is fixedly connected to the inner wall of the spray tower 1. The second water level monitor 19 is located below the air inlet pipe of the spray tower 1. Both the first water level monitor 18 and the second water level monitor 19 are electrically connected to the water pump 4.

[0031] The first water level monitor 18, which is fixedly connected to the inner wall of the treatment tank 2, is located below the outlet of the drain pipe 12 and can monitor the water level of the treatment liquid in the treatment tank 2 in real time; the second water level monitor 19, which is fixedly connected to the inner wall of the spray tower 1, is located below the air inlet pipe of the spray tower 1 and is used to monitor the water level of the treatment liquid in the spray tower 1 in real time.

[0032] When the first water level monitor 18 detects that the water level of the treatment liquid in the treatment tank 2 is lower than the set value, it will send an electrical signal to the water pump 4. After receiving the signal, the water pump 4 will start and transport the treatment liquid in the spray tower 1 to the treatment tank 2 through the delivery pipe 3 until the water level of the treatment liquid in the treatment tank 2 reaches the set standard. Then, the first water level monitor 18 will send a signal again to stop the water pump 4. If the first water level monitor 18 detects that the water level in the treatment tank 2 is too high, it will also trigger the water pump 4 to adjust and transport the excess treatment liquid in the treatment tank 2 to the spray tower 1.

[0033] Similarly, when the second water level monitor 19 detects an abnormal water level in the treatment liquid in the spray tower 1, it will also send an electrical signal to the water pump 4 to control the water pump 4 to transport the treatment liquid in the treatment tank 2 to the spray tower 1, or transport it in the reverse direction, so as to maintain the stability of the treatment liquid water level in the spray tower 1 and ensure the continuous and stable operation of the entire waste gas treatment device.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
