Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, specifically a cooling device for phosphine purification. Background Technology

[0002] Phosphine purification is an important environmental protection process, the main purpose of which is to remove or transform phosphine, a toxic and harmful gas, because phosphine can cause serious harm to the environment and human health. Phosphine purification plays a key role in many fields such as industrial waste gas treatment and agricultural waste treatment.

[0003] When it comes to exhaust gas recovery, the cooling device for phosphine purification becomes a key front-end device in the exhaust gas recovery system. It can lower the temperature of exhaust gas containing phosphine, allowing phosphine to change from a gaseous state to a liquid state or a state that is easier to be adsorbed and absorbed at a suitable low temperature, which facilitates subsequent recovery and treatment.

[0004] When the cooling device for phosphine purification is in use, the exhaust gas generated during purification in the purification tank is transferred to the cooling device through pipes. Because the pipes are exposed to the outside, impurities in the air will adhere to the surface of the pipes, thus affecting their heat dissipation effect and increasing the cooling time after entering the cooling device.

[0005] Therefore, a cooling device for phosphine purification is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A cooling device for phosphine purification treatment, comprising a purification tank, the side wall of which is connected to a pipe; a pair of protective shells are provided on the top of the purification tank; one side of each protective shell is perforated; a semi-circular hole is provided at the bottom of each protective shell; the semi-circular hole and the pipe are correspondingly arranged; an air pump is fixedly connected to the side wall of the protective shell; an air inlet is provided inside the protective shell; a plurality of first damping springs are fixedly connected to the inner wall of the protective shell; a square plate is fixedly connected to the end of each first damping spring; the... Multiple arc-shaped plates are fixed to the side wall of the square plate; the arc-shaped plates are semi-circular and correspond to the semi-circular holes; by adding a protective shell, external dust and impurities can adhere to the surface of the pipe, thereby affecting the heat dissipation of the pipe itself. At the same time, when the air pump blows air into the protective shell, it can push the heat generated by the pipe out of the protective shell, thereby reducing the time that the heat exists inside the protective shell. When the exhaust gas passes through the pipe, the airflow blown out by the air pump will cool the pipe, thereby reducing the temperature of the exhaust gas inside the pipe. This pre-cools the exhaust gas, thereby reducing the processing time after entering the cooling device.

[0008] Preferably, a water spray pipe is fixedly connected to the inner wall of the protective shell; multiple atomizing nozzles are fixedly connected to the surface of the water spray pipe; a water guide pipe is connected to the top of the water spray pipe; the water guide pipe is through the protective shell; by increasing the atomizing nozzles to cool the pipe, the water source can be broken into small parts, thereby increasing the contact area with the pipe. At the same time, using the atomizing nozzles can quickly attach the sprayed water source to the surface of the pipe for evaporation, thereby carrying away the heat, which can increase the cooling rate of the pipe and reduce the temperature of the pipe, so that the temperature of the exhaust gas drops faster when it passes through the inside of the pipe.

[0009] Preferably, multiple baffles are fixed to the top of the square plate; the top of the baffles is inclined; by adding baffles, the airflow blown out by the air pump can be guided, thereby increasing the contact area between the airflow and the protective shell, thereby increasing the rate of airflow heat dissipation. At the same time, due to the angle of the baffles, the water source will also move according to the surface of the baffle after falling onto the baffle, thus dripping onto the surface of the pipe, thereby increasing the utilization rate of the water source.

[0010] Preferably, a plurality of second damping springs are fixedly connected inside the semicircular hole; an elastic cloth is fixedly connected to the end of the semicircular hole; by adding the elastic cloth, the contact between the semicircular hole and the pipe can be increased when the protective shell is assembled, thereby increasing the stability during installation. At the same time, the second damping springs will press the elastic cloth tightly against the surface of the pipe, thereby making full contact with the pipe.

[0011] Preferably, a pair of rubber sheets are fixed to the side wall of the protective shell; the rubber sheets are located on the surface of the air inlet and are semi-circular; by adding the rubber sheets, the air inlet can be blocked, and the airflow from the air pump will push the rubber sheets open, allowing the airflow to enter the interior of the protective shell, thereby automatically opening and closing the air inlet.

[0012] Preferably, a ribbon is fixed to the side wall of the rubber sheet; the ribbon is located at the end of the rubber sheet; by adding the ribbon, the airflow can be guided into the protective shell, thereby increasing the range of airflow inside the protective shell and thus increasing the airflow speed inside the protective shell.

[0013] The advantages of this utility model are:

[0014] 1. The cooling device for phosphine purification described in this utility model, by adding a protective shell, allows external dust and impurities to adhere to the surface of the pipe, thereby affecting the heat dissipation of the pipe itself. At the same time, when the air pump blows air into the protective shell, it can push the heat generated by the pipe out of the protective shell, thereby reducing the time that the heat exists inside the protective shell. When the exhaust gas passes through the pipe, the airflow blown out by the air pump will cool the pipe, thereby reducing the temperature of the exhaust gas inside the pipe. This pre-cools the exhaust gas, thereby reducing the processing time after it enters the cooling device.

[0015] 2. The cooling device for phosphine purification described in this utility model can reduce the water source by adding atomizing nozzles to cool the pipeline, thereby increasing the contact area with the pipeline. At the same time, the atomizing nozzles can quickly attach the sprayed water source to the pipeline surface for evaporation, thereby carrying away the heat. This can increase the cooling rate of the pipeline and reduce the temperature of the pipeline, so that the temperature of the exhaust gas drops faster when it passes through the inside of the pipeline.

[0024] 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 scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6 As shown in the embodiment of this utility model, a cooling device for phosphine purification includes a purification tank 1, with a pipe 11 connected to the side wall of the purification tank 1; a pair of protective shells 12 are provided on the top of the purification tank 1; one side of each protective shell 12 is perforated; a semi-circular hole 13 is provided at the bottom of each protective shell 12; the semi-circular hole 13 and the pipe 11 are correspondingly arranged; an air pump 14 is fixedly connected to the side wall of the protective shell 12; an air inlet 15 is provided inside the protective shell 12; and a plurality of first damping springs 16 are fixedly connected to the inner wall of the protective shell 12. A square plate 17 is fixedly connected to the end of the first damping spring 16; multiple arc-shaped plates 18 are fixedly connected to the side wall of the square plate 17; the arc-shaped plates 18 are semi-circular and correspond to the semi-circular holes 13; during operation, the pipe 11 is wrapped by first merging the two protective shells 12. After the protective shells 12 are merged, the arc-shaped plates 18 will first contact the outer wall of the pipe 11 to support and clamp the pipe 11, allowing it to enter the interior of the arc-shaped plates 18. Subsequently, the first damping spring 16 will contract, reducing the compression on the square plate 17, thereby fixing the pipe 11. Then, the air pump 14 is started, allowing air to flow into the protective shell 12 through the air inlet 15, blowing air into the protective shell 12 and accelerating the airflow inside. Subsequently, air is ejected from the holes on the other side of the protective shell 12, thus completing the air circulation inside the protective shell 12. When the pipe 11 transmits the exhaust gas inside the purification tank 1, the protective shell 12 blocks outside air from directly affecting the pipe 11. Simultaneously, the air pump 14 blows air into the protective shell 12, causing the airflow to contact the surface of the pipe 11, thereby cooling the pipe 11 and reducing its temperature. Increase; by adding a protective shell 12, external dust and impurities can adhere to the surface of the pipe 11, thereby affecting the heat dissipation of the pipe 11 itself. At the same time, when the air pump 14 blows air into the protective shell 12, it can push the heat generated by the pipe 11 out of the protective shell 12, thereby reducing the time that the heat exists inside the protective shell 12. When the exhaust gas passes through the pipe 11 and is in operation, the airflow blown out by the air pump 14 will cool the pipe 11, thereby reducing the exhaust gas temperature inside the pipe 11, thus cooling the exhaust gas in advance and reducing the processing time after entering the cooling device.

[0027] like Figures 2 to 3As shown, a water spray pipe 2 is fixedly connected to the inner wall of the protective shell 12; multiple atomizing nozzles 21 are fixedly connected to the surface of the water spray pipe 2; a water guide pipe 22 is connected to the top of the water spray pipe 2; the water guide pipe 22 is through the protective shell 12; during operation, when the air pump 14 blows air into the protective shell 12, the water guide pipe 22 is connected to the water pump to draw water into the water spray pipe 2, and then the water is sprayed out through the atomizing nozzles 21 onto the surface of the pipe 11, so that the water droplets adhere to the surface of the pipe 11, absorb heat and evaporate, and then the air blown out by the air pump 14... The water flow is discharged from the protective shell 12, and the water mist sprayed by the atomizing nozzle 21 is sprayed onto the surface of the pipe 11 to cool it down. By increasing the cooling of the pipe 11 by the atomizing nozzle 21, the water source can be broken into small parts, thereby increasing the contact area with the pipe 11. At the same time, the atomizing nozzle 21 can quickly attach the sprayed water source to the surface of the pipe 11 for evaporation, thereby carrying away the heat. This can increase the cooling rate of the pipe 11 and reduce the temperature of the pipe 11, so that the temperature drops faster when the exhaust gas passes through the inside of the pipe 11.

[0028] like Figures 2 to 6 As shown, multiple baffles 3 are fixed to the top of the square plate 17; the top of the baffles 3 is inclined; during operation, when the airflow blown out by the air pump 14 enters the semi-circular hole 13, the airflow will contact the baffles 3 and flow along the angle of the baffles 3 to the surface of the pipe 11, thereby increasing the contact between the airflow and the protective shell 12. At the same time, the water mist sprayed by the atomizing nozzle 21 falls onto the baffles 3 and slides down the surface of the baffles 3 to the lowest point of the baffles 3 and drips onto the surface of the pipe 11. By adding baffles 3, the airflow blown out by the air pump 14 can be guided, thereby increasing the contact area between the airflow and the protective shell 12 and increasing the rate of airflow heat dissipation. At the same time, due to the angle of the baffles 3, the water source will also move according to the surface of the baffles 3 after falling onto the baffles 3 and drip onto the surface of the pipe 11, thereby increasing the utilization rate of the water source.

[0029] like Figure 4 As shown, multiple second damping springs 4 are fixedly connected inside the semicircular hole 13; an elastic cloth 41 is fixedly connected to the end of the semicircular hole 13; during operation, when the semicircular hole 13 is closed, the elastic cloth 41 will first contact the surface of the pipe 11, and then the second damping springs 4 will provide support for the elastic cloth 41, thereby sticking the elastic cloth 41 to the surface of the protective shell 12, thereby increasing the contact between the semicircular hole 13 and the pipe 11 and reducing the gap between the joints; by increasing the elastic cloth 41, the contact between the semicircular hole 13 and the pipe 11 can be increased when the protective shell 12 is closed, thereby increasing the stability during installation, and at the same time, the second damping springs 4 will press the elastic cloth 41 tightly against the surface of the pipe 11, thereby fully contacting the pipe 11.

[0030] like Figure 5As shown, a pair of rubber sheets 5 are fixed to the side wall of the protective shell 12; the rubber sheets 5 are located on the surface of the air inlet 15 and are semi-circular; during operation, when the air pump 14 blows air into the protective shell 12, the rubber sheets 5 will swing accordingly, allowing the airflow blown by the air pump 14 to enter the interior of the protective shell 12 through the air inlet 15. When the air pump 14 is not in operation, the rubber sheets 5 will return to their initial state, thereby sealing the air inlet 15 and preventing external dust from entering the interior of the protective shell 12; by adding rubber sheets 5, the air inlet 15 can be sealed, so that when the air pump 14 is working, the airflow will push the rubber sheets 5 open, allowing the airflow to enter the interior of the protective shell 12, thereby automatically opening and closing the air inlet 15.

[0031] like Figure 5 As shown, a ribbon 6 is fixed to the side wall of the rubber sheet 5; the ribbon 6 is located at the end of the rubber sheet 5; during operation, when the rubber sheet 5 moves with the airflow, the ribbon 6 also moves to disperse the airflow into the protective shell 12, so that the airflow inside the protective shell 12 flows and thus accelerates the air circulation inside the protective shell 12; by adding the ribbon 6, the guidance of the airflow when it enters the protective shell 12 can be increased, thereby increasing the range of airflow activity inside the protective shell 12, and thus increasing the airflow speed inside the protective shell 12.

[0032] Working principle: First, the two protective shells 12 are joined together to enclose the pipe 11. After the protective shells 12 are joined, the arc-shaped plate 18 will first contact the outer wall of the pipe 11 to support and clamp the pipe 11, allowing it to enter the interior of the arc-shaped plate 18. Then, the first damping spring 16 will contract to reduce the compression on the square plate 17, thereby fixing the pipe 11. Then, the air pump 14 is started, allowing air to flow into the interior of the protective shell 12 through the air inlet 15, blowing air into the interior of the protective shell 12. This increases the airflow inside the protective shell 12, and then the air will be ejected from the hole on the other side of the protective shell 12, thus completing the process inside the protective shell 12. In the air circulation process, when the exhaust gas inside the purification tank 1 is transmitted through the pipe 11, the protective shell 12 blocks the outside air from directly affecting the pipe 11. Simultaneously, the air pump 14 blows air into the protective shell 12, causing the airflow to contact the surface of the pipe 11, thereby cooling the pipe 11 and reducing its temperature rise. While the air pump 14 is blowing air into the protective shell 12, the water pipe 22 is connected to a water pump, drawing water into the spray pipe 2. The water is then sprayed onto the surface of the pipe 11 through the atomizing nozzle 21, causing water droplets to adhere to the surface, absorb heat, and evaporate. The water is then expelled from the protective shell 12 by the airflow blown out by the air pump 14. This process utilizes atomized spraying... The water mist sprayed from nozzle 21 sprays onto the surface of pipe 11 to cool it down. When the airflow blown by air pump 14 enters the interior of protective shell 12, the airflow will contact baffle 3 and flow along the angle of baffle 3 to the surface of pipe 11, thereby increasing the contact between the airflow and pipe 11. At the same time, the water mist sprayed from atomizing nozzle 21 falls onto baffle 3 and slides down the surface of baffle 3 to the lowest point of baffle 3, thus dripping onto the surface of pipe 11. When the semi-circular holes 13 are closed, the elastic cloth 41 will first contact the surface of pipe 11, and then the second damping spring 4 will provide support for the elastic cloth 41, thereby sticking the elastic cloth 41 to the surface of protective shell 12. This increases the contact between the semicircular hole 13 and the pipe 11, thereby reducing the gap between the connection points. When the air pump 14 blows air into the protective shell 12, the rubber sheet 5 will swing accordingly, allowing the airflow blown by the air pump 14 to enter the protective shell 12 through the air inlet 15. When the air pump 14 is not in operation, the rubber sheet 5 will return to its initial state, thereby sealing the air inlet 15 and preventing external dust from entering the protective shell 12. When the rubber sheet 5 floats with the airflow, the ribbon 6 will also float, dispersing the airflow into the protective shell 12, allowing the airflow inside the protective shell 12 to flow, thereby accelerating the air circulation inside the protective shell 12.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
