Description

Technical Field

[0001] The utility model relates to the technical field of reaction equipment, in particular to a reaction tank for gas production. Background Art

[0002] The reaction tank is a commonly used reaction equipment in chemical plants. It mainly uses a motor to drive the stirring shaft to stir the reactants to make them react fully to obtain the required substances. The reaction tank can withstand a certain pressure and is used to complete multiphase reactions such as gas-liquid, liquid-liquid, and gas-liquid-solid.

[0003] It has been found in actual use that the existing reaction tank has the following deficiencies during gas reaction:

[0004] During the reaction process, the materials release heat and generate pressure. The existing reaction tanks rely solely on the outer jacket of the tank for heat exchange, which is limited. In addition, the larger the tank diameter, the smaller the heat exchange area per unit tank volume. However, the amount of reactants is increasing. When the reaction releases heat, if the heat exchange effect cannot be guaranteed, the process parameters and temperature in the production process cannot be controlled, affecting the quality of the product.

[0005] In addition, the reaction process inside the reactor will produce gas. To ensure safety, most existing reactors are sealed structures. However, as the reaction proceeds, the internal gas pressure will change. The pressure on the inner wall of the reactor is too high. If the pressure is directly released during the gas reaction, it will not only be difficult to control the pressure release degree, but the pressure release will also cause gas discharge and affect the normal reaction.

[0006] Therefore, the present application provides a reaction tank for gas production to meet the demand. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a reaction tank for gas production.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] A reaction tank for gas production, comprising: a reaction tank body, a jacket, a stirring mechanism, an air inlet pipe, an air outlet pipe, a liquid inlet pipe, a liquid outlet pipe, a condenser, a connecting pipe, a water storage pipe, a water storage tank, a drain pipe and a vent pipe, wherein a jacket is installed at the outer end of the bottom of the reaction tank body, a stirring mechanism is installed at the top of the reaction tank body, an air inlet pipe is installed at the bottom of the reaction tank body, an air outlet pipe is installed at the upper right end of the reaction tank body, a liquid inlet pipe is installed at the lower end of the side of the reaction tank body, a liquid outlet pipe is installed at the upper end of the reaction tank body, a condenser is installed at the outer end of the liquid outlet pipe, a connecting pipe is installed at the upper left end of the reaction tank body, a water storage pipe is installed on the left side of the connecting pipe, a water storage tank is installed on the top of the water storage pipe, a drain pipe is installed at the bottom of the water storage pipe, and a vent pipe is installed on the right side of the connecting pipe.

[0010] Preferably, two groups of the liquid inlet pipe, the liquid outlet pipe and the condenser are provided, and the two groups of the liquid inlet pipe, the liquid outlet pipe and the condenser are respectively located on the left and right sides of the reaction tank body.

[0011] Preferably, the liquid inlet pipe transversely penetrates the inner wall of the reaction tank body and extends to the interior of the reaction tank body to be connected with the bottom of the liquid outlet pipe.

[0012] Preferably, the liquid outlet pipe vertically penetrates the inner wall of the reaction tank body and extends to the inner lower end of the reaction tank body.

[0013] Preferably, the condenser is installed on the left and right sides of the interior of the reaction tank body through a liquid inlet pipe and a liquid outlet pipe, and the condenser is arranged vertically.

[0014] Preferably, the condenser is in a U-shape, and the upper and lower ends of the condenser are respectively connected to the upper and lower ends of the liquid outlet pipe.

[0015] Preferably, the vent pipe is in an "L" shape, and the vent pipe passes through the inner wall of the reaction tank body vertically downward, and the pipe opening of the vent pipe is higher than the pipe opening of the exhaust pipe.

[0016] Preferably, the water storage pipe is in a "U" shape, and the water storage pipe is connected to the connecting pipe, the water storage tank and the drainage pipe.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. By arranging the condenser inside the reactor, the vertically arranged condenser can fully contact the gas and liquid in the reactor. When the liquid is extracted from the condenser, the condenser moves up and down to exchange heat along the reactor, ensuring the contact area between the condenser and the liquid in the reactor. This can increase the heat exchange area per unit reactor, avoid the pressure generated by rapid heating during the gas oxidation reaction, and effectively reduce safety risks in production.

[0019] 2. During the reaction, the gas generated in the reaction tank can rise from the lower end into the vent pipe, which is conducive to ensuring the pressure stability in the tank during the reaction. The "U"-shaped water storage pipe forms a water seal structure to prevent the gas from overflowing and volatilizing, so that the volatilized gas can be absorbed by water, thereby preventing the gas accumulated after the lid is opened after the reaction from volatilizing directly to the outside, making the reaction safer.

DETAILED DESCRIPTION

[0027] like Figure 1 、 Figure 2 and Figure 3The embodiment of the utility model provides a gas production reaction tank, comprising: a reaction tank body 1, a jacket 2, a stirring mechanism 3, an air inlet pipe 4, an air outlet pipe 5, a liquid inlet pipe 6, a liquid outlet pipe 7, a condenser pipe 8, a connecting pipe 9, a water storage pipe 10, a water storage tank 11, a drain pipe 12 and a vent pipe 13. The jacket 2 is installed at the outer end of the bottom of the reaction tank body 1, the stirring mechanism 3 is installed on the top of the reaction tank body 1, the air inlet pipe 4 is installed at the bottom of the reaction tank body 1, and the reaction tank body 1 is provided with a plurality of channels. An air outlet pipe 5 is installed at the upper right end of the tank body 1, a liquid inlet pipe 6 is installed at the lower end of the side of the reaction tank body 1, a liquid outlet pipe 7 is installed at the upper end of the reaction tank body 1, and a condenser 8 is installed at the outer end of the liquid outlet pipe 7. A connecting pipe 9 is installed at the upper left end of the reaction tank body 1, a water storage pipe 10 is installed on the left side of the connecting pipe 9, a water storage tank 11 is installed on the top of the water storage pipe 10, a drain pipe 12 is installed at the bottom of the water storage pipe 10, and a ventilation pipe 13 is installed on the right side of the connecting pipe 9.

[0028] In this embodiment, two groups of liquid inlet pipes 6, liquid outlet pipes 7 and condenser pipes 8 are provided, and the two groups of liquid inlet pipes 6, liquid outlet pipes 7 and condenser pipes 8 are respectively located on the left and right sides of the reaction tank body 1. By arranging the condenser pipes 8 inside the reaction tank body 1, the vertically arranged condenser pipes 8 can fully contact the gas and liquid in the reaction tank. When the liquid is extracted from the condenser pipes 8, the up and down movement can be carried out along the reaction tank for heat exchange, thereby ensuring the contact area between the condenser pipes 8 and the liquid in the reaction tank, and can increase the heat exchange area of the unit reaction tank, thereby avoiding the pressure generated by rapid heat generation during the gas oxidation reaction, and effectively reducing the safety risks in production.

[0029] In this embodiment, the liquid inlet pipe 6 horizontally passes through the inner wall of the reaction tank body 1 and extends to the interior of the reaction tank body 1 and is connected to the bottom of the liquid outlet pipe 7. The cooling liquid can pass from the liquid inlet pipe 6 into the lower end of the liquid outlet pipe 7 inside the reaction tank body 1, and then enter the bottom of the condenser 8 from the lower end of the liquid outlet pipe 7. The cooling liquid spreads throughout the entire condenser 8 from bottom to top to exchange heat with the liquid in the reaction tank body 1. The cooling water enters at the low end and exits at the high end. The water will encounter heat in the condenser 8 and automatically flow upward, achieving a greater cooling effect. The water and steam countercurrent make the temperature at the end of the condenser the lowest, so that the steam is fully condensed, which can improve the heat exchange efficiency of the condenser.

[0030] In this embodiment, the liquid outlet pipe 7 vertically penetrates the inner wall of the reaction tank body 1 and extends to the lower end of the inner part of the reaction tank body 1.

[0031] In this embodiment, the condenser 8 is installed on the left and right sides of the interior of the reaction tank body 1 through the liquid inlet pipe 6 and the liquid outlet pipe 7, and the condenser 7 is arranged vertically.

[0032] In this embodiment, the condenser 7 is in a U-shape, and the upper and lower ends of the condenser 7 are respectively connected to the upper and lower ends of the liquid outlet pipe 7. The U-shaped condenser 7 can not only ensure the contact area with the liquid, but also allow the coolant to form a passage to quickly take away the heat.

[0033] In this embodiment, the vent pipe 13 is in an "L" shape, and the vent pipe 13 passes through the inner wall of the reaction tank body 1 vertically downward, and the pipe mouth of the vent pipe 13 is higher than the pipe mouth of the outlet pipe 5, so that the gas generated in the reaction tank body 1 can rise from the lower end into the vent pipe 13, which is beneficial to ensure the pressure stability in the tank body during the reaction.

[0034] In this embodiment, the water storage pipe 10 is in a "U" shape, and the water storage pipe 10 is connected to the connecting pipe 9, the water storage tank 11 and the drain pipe 12. The "U"-shaped water storage pipe 10 forms a water seal structure. The water storage tank 11 injects water into the water storage pipe 10, and the overflowing volatile gas is blocked by the water storage pipe 10 so that the volatilized gas can be absorbed by water, thereby preventing the gas accumulated when the cover is opened after the reaction from volatilizing directly to the outside, making the reaction safer.
