Embodiment Construction
[0045] Attached to the following Figure 1-4 This application will be described in further detail.
[0046] When using the bromine method to produce methyl bromide, firstly, the sulfur bromide is prepared by mixing bromine and sulfur, and then the sulfur bromide is dropped into methanol, and the reaction is carried out at 50-60 degrees Celsius, and the reactants are continuously evaporated to obtain methyl bromide. Washing with 5% caustic soda solution, washing with sulfuric acid, drying again, and finally compressing and liquefying to obtain the product methyl bromide
[0047] The embodiment of the present application discloses a methyl bromide purification device.
[0048] refer to figure 1 , the methyl bromide purification device includes a tank 1, and two partitions 2 are arranged side by side in the tank 1, and the two partitions 2 divide the tank 1 into three chambers, and from top to bottom are drying chambers 11 , heat exchange chamber 12 and pickling chamber 13 . ...

The application relates to a methyl bromide purification device, which includes a tank body, the tank body is provided with a drying chamber and a pickling chamber that communicate with each other, the drying chamber is used to store concentrated sulfuric acid, and the pickling chamber is located below the drying chamber The tank body is provided with a liquid inlet and an air outlet both connected to the drying chamber, and the tank body is also provided with a liquid outlet and an air inlet connected to the pickling chamber. The application has the advantages of using concentrated sulfuric acid to dry methyl bromide gas, and using concentrated sulfuric acid to absorb water and dilute the formed dilute sulfuric acid as a reagent in the previous process of drying to wash the methyl bromide gas, reduce the types of chemicals, facilitate the storage of chemicals, and help reduce production. cost effect.
Description
technical field [0001] The application relates to the field of chemical production equipment, in particular to a methyl bromide purification device. Background technique [0002] Methyl bromide, also known as methyl bromide, methyl bromide or methyl bromide, is a colorless, odorless gas. It has a strong fumigation effect, can effectively kill various harmful organisms, and can be used as a disinfectant for buildings, ships and aircraft. [0003] When using the bromine method to produce methyl bromide, firstly, the sulfur bromide is prepared by mixing bromine and sulfur, and then the sulfur bromide is dropped into methanol, and the reaction is carried out at 50-60 degrees Celsius, and the reactants are continuously evaporated to obtain methyl bromide. Washing with 5% caustic soda solution, washing with sulfuric acid, drying with anhydrous calcium chloride, and finally compressing and liquefying to obtain the product methyl bromide. [0004] In view of the above-mentioned re...
