Device for cooling mercury vapor through water circulation

Abstract

The invention relates to the technical field of mercury vapor cooling, and particularly relates to a device for cooling mercury vapor through water circulation. By improvement of the structure of the cooling device, the device comprises a tank, a cooling tower arranged on the tank, an inlet formed in the side surface of the tank and an outlet formed at the side surface opposite to the inlet and at the skew diagonal position of the inlet, and further causes the water circulation cooling of the mercury vapor to be realized, the contact time of water and the vapor to be relatively long and a heat exchange degree to be relatively high; and through reasonable design of the device, a vapor circulation pipe is arranged in a cooling water pipeline in a sleeving manner, the probability of leaking the mercury vapor to environments and polluting and corroding the outer wall of the cooling tower by the mercury vapor is relatively low, the emission rate of the mercury vapor and the environment pollution rate are reduced, and the cooling effect of the mercury vapor is improved.

Description

technical field [0001] The invention relates to the technical field of mercury vapor cooling, in particular to a water circulation cooling device for mercury vapor. Background technique [0002] Mercury is a highly corrosive substance that can corrode metals such as cast iron. In the process of producing and preparing mercury, the equipment requirements for mercury are relatively strict, making it difficult for a large number of cast iron and metal products to be used as mercury in the production process. Even if the equipment with a thickness of several tens of centimeters of steel pipe and steel plate is used as the raw material for the production and treatment of mercury, the equipment will be corroded and empty during the long-term production process, which will further affect the production. The environment poses a threat, which also makes the service life of the equipment shorter and the cost of mercury preparation is higher. Especially for equipment or devices that c...

[0002] Mercury is a highly corrosive substance that can corrode metals such as cast iron. In the process of producing and preparing mercury, the equipment requirements for mercury are relatively strict, making it difficult for a large number of cast iron and metal products to be used as mercury in the production process. Even if the equipment with a thickness of several tens of centimeters of steel pipe and steel plate is used as the raw material for the production and treatment of mercury, the equipment will be corroded and empty during the long-term production process, which will further affect the production. The environment poses a threat, but also makes the service life of the equipment shorter, and the cost of mercury preparation is higher

Especially for equipment or devices that cool mercury into liquid and recover mercury vapor in the production process through water circulation cooling, when it is made of cast iron and other metals, its heat dissipation effect is better and the heat exchange rate is higher, but , the long-term corrosion of mercury will cause mercury vapor to corrode the equipment, causing mercury and water to mix, causing water pollution; mercury vapor leaking into the environment, causing pollution to the atmosphere and other environments, and at the same time, the recovery rate of mercury Lower, increasing the cost of mercury recovery
