The distillation tank is a device for separating homogeneous liquid mixture, is one of the most commonly used devices in chemical industry, and is also a device with high risk and easy leakage and fire explosion accidents. The materials in the distillation tank are mostly flammable and explosive dangerous chemicals, once the materials are leaked, the materials and air form explosive mixtures, and fire explosion can be caused when the materials meet open fire. If the material is a toxic chemical, the leakage may result in poisoning of personnel.
Specifically, in the working process of the distillation tank, the material is heated, when the temperature reaches the boiling point of a certain component, the component is converted from a liquid state into a gas state, and the gas is discharged from the distillation pipe and condensed and collected. In the process, the problem of ultrahigh pressure in the tank caused by temperature fluctuation, material fluctuation, blockage of a distillation pipe or other reasons can occur, and the tank body can be cracked, so that inflammable or toxic gas is leaked, and further explosion or toxic accidents are caused. In the prior art, a tank body is generally provided with an explosion venting port, when the pressure exceeds a limit value, the explosion venting port is opened to release the pressure, and the pressure in the tank is reduced, so that the tank body is prevented from being broken. However, after the explosion venting port is opened, gas leakage still exists, and if open fire or a power supply exists on the site, fire accidents are easily caused. If toxic gas exists during explosion venting, the health of field workers can be harmed.

When the pressure in the tank exceeds the limit value, the explosion venting bolt falls off, and the sealing end faces of the tank body and the cover body are disconnected. Under the effect of the pressure in the tank and the pressure spring, the annular sleeve moves upwards along the tank body, the volume of the tank body is increased, and the pressure in the tank can be reduced. At the moment, the annular sleeve still forms a seal with the side wall of the tank body, so that gas in the tank body is prevented from leaking. In addition, after the annular sleeve is moved on, the lower part of the tank body is exposed, the annular sleeve does not heat the materials in the tank body, the heat dissipation of the tank body after being exposed is accelerated, the temperature of the materials is rapidly reduced, the materials can be prevented from continuously evaporating, and the pressure in the tank body is favorably reduced.
In the scheme, the cover body and the annular sleeve adopt an integrated structure, so that the cover body and the annular sleeve form sealing. Because the distillation pipe and the feeding pipe are arranged on the cover body, when the annular sleeve moves upwards, the distillation pipe and the feeding pipe cannot interfere with the annular sleeve to move upwards. The distillation tube and the feed tube may be provided as a hose connection structure.
The strength of the hose connection is not as strong as the fixed steel pipe connection. This embodiment provides a structure, and inlet pipe and distillation tube adopt fixed knot to construct, and do not influence the upshift of ring sheath when letting out the explosion.
