[0018] A second tee 14 is provided at the outlet of the manifold 9. The second tee 14 has downward and upward outlets and a solenoid valve is also provided at the upward outlet. The downward outlet of the second tee 14 extends into the water cooling jacket 3 and is coaxially arranged with the water cooling jacket 3. A guide cone 15 with a downward pointed tip is also coaxially fixed at the upward outlet of the second tee 14. The water flow discharged from the upward outlet of the second tee 14 impacts the guide cone 15 and then spreads into a curtain; a water supply pipe 16 with a solenoid valve is also provided on the manifold 9. In case of emergency rescue, supplementary water is injected into the manifold 9 through the water supply pipe 16 to ensure that the water source in the system around the tank body 1 is sufficient;

[0019] A diverter plate 17 matched with the downward outlet of the second tee 14 is arranged in the water-cooling jacket 3. The diverter plate 17 includes a plurality of triangular baffles uniformly distributed along the circumferential direction of the cross section of the water-cooling jacket 3. Flow grooves 18 are formed between adjacent triangular baffles. A vertical flow channel 19 corresponding to the flow grooves 18 is arranged on the circumferential surface of the water-cooling jacket 3. The water flow discharged from the downward outlet of the second tee 14 hits the diverter plate 17 and enters each flow groove 18 respectively, and then enters the corresponding vertical flow channel 19. During the flow, the water flow exchanges heat between the walls of the tank body 1. A spiral flow guide 20 is arranged in the vertical flow channel 19 to extend the heat exchange path of the water flow and prevent a large amount of outer circle water flow from directly flowing down without contacting the inner wall of the water-cooling jacket 3. The spiral flow guide 20 includes a vertical rod and a spiral sheet fixed on the vertical rod. The lower end of the vertical rod is connected to the inner bottom surface of the water-cooling jacket 3. The bottom of the water-cooling jacket 3 has a collecting ring 21, and the water inlet pipe 7 is connected to the collecting ring.

[0020] The above-mentioned solenoid valves are electrically connected and controlled by a PLC controller or are all normally closed solenoid valves. In this way, when a dangerous situation occurs, the power supply of the solenoid valve can be directly cut off. At this time, the water supply pipe 16, the upward outlet of the second three-way 14 and the downward outlet of the first three-way 10 can all discharge water;

[0021] The working principle of this embodiment is:

[0022] When the temperature is high in summer, the water cooling jacket 3 is kept working. Specifically, the second three-way 14 sends water to the water cooling jacket 3 to take away the heat of the tank body 1. After absorbing the heat, the water flows through the water inlet pipe 7 and the water pump into each coil group 5. The induced draft fan 6 draws air upward, and the external air flow passes through the coil group to take away the heat of the water flow. The cooled water flows into the collecting pipe 9 and returns to the second three-way 14. This can prevent the tank body 1 from bursting due to pressure increase in hot summer. When the tank body 1 leaks accidentally, the second three-way 14 drains water upward to form a water curtain to wrap the upper part of the tank body 1. At the same time, the first three-way 14 on the water outlet pipe drains water upward to form a water curtain to wrap the upper part of the tank body 1. A three-way valve 10 drains water downward to form two layers of water curtains inside and outside the cofferdam 2. The cofferdam 2 is thin at the top and thick at the bottom. The leaked liquid is mixed with the water flow and diluted and blocked in the cofferdam 2. After the danger is eliminated, it is discharged through the liquid extraction port 4. Compared with the prior art, this embodiment uses a water cooling jacket 3 to cool the tank body 1, and the circulating water returns to the water cooling jacket 3 after being cooled by the cooling mechanism. When the tank body 1 leaks, the present application can also generate a spray water curtain above the tank body 1 and a water curtain around the tank body 1 to dilute and prevent the dimethyl disulfide liquid from escaping, which is beneficial to ensuring the safety of the surrounding facilities and personnel.

[0023] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
