Description

TECHNICAL FIELD

[0001] The utility model relates to carbon fluoride gas processing technical field, specifically is a kind of carbon fluoride gas processing equipment. BACKGROUND

[0002] Carbon fluoride is a colorless gas.Under standard conditions, the density is greater than air, and carbon fluoride is a highly toxic gas. After inhalation, it can cause serious irritation and damage to the respiratory tract, eyes and skin, etc. It can react with moisture in the respiratory tract to generate hydrogen fluoride and carbon dioxide, which can corrode the respiratory mucosa and cause symptoms such as coughing, difficulty breathing, etc. In severe cases, it can lead to pulmonary edema and even death. When operating carbon fluoride, it must be done in a well-ventilated environment, such as a fume hood or a laboratory or workshop equipped with a high-efficiency ventilation system. The operator needs to wear personal protective equipment, including a gas mask, chemical protective gloves and protective clothing, etc. If a leak occurs, personnel should be evacuated immediately and appropriate emergency measures should be taken, such as diluting and absorbing the leaked gas with spray water. Currently, water absorption method is commonly used in industry to treat carbon fluoride gas by reacting carbon fluoride with water to generate carbon dioxide and hydrogen fluoride.

[0003] However, when the existing workers use the water absorption method to treat carbon fluoride gas, the workers need to pass the carbon fluoride gas into the water. When the carbon fluoride gas enters the water body, it will produce a bubble, causing the carbon fluoride gas to move to the water surface, and thus the reaction between the carbon fluoride gas and the water mostly occurs on the contact surface between the water and the carbon fluoride gas, which leads to insufficient direct contact between most of the carbon fluoride gas and the water, and thus affects the treatment efficiency of the carbon fluoride gas. Therefore, it does not meet the current needs, and thus we propose a carbon fluoride gas treatment equipment. Utility model content
