Equipment used in process for recovering organic matters in hydrogen chloride gas

Abstract

The invention discloses equipment used in a process for recovering organic matters in hydrogen chloride gas. The equipment includes a tail gas absorption device, and a prompting device is arranged atthe bottom on the left side of the tail gas absorption device; by a fluid infusion device, the equipment can achieve automatic supplementation of absorption liquid, a collection device collects wasteabsorption liquid and performs real-time monitoring of the collection amount, cooperation of the collection device and the prompting device can alert workers to transfer of the waste absorption liquid, thus ensuring timely transfer of the waste absorption liquid and preventing excessive waste absorption liquid from overflowing and polluting the environment, and through coordination of a liquid storage device, a flow guide device and a liquid change device, the equipment can achieve replacement of the absorption liquid without stop, thus guaranteeing continuous work of the equipment, improvingthe tail gas treatment efficiency, providing guarantee for high-efficiency production of methane chloride, and improving the practicability of the equipment used by the process for recovering organicmatters in hydrogen chloride gas.

Description

technical field [0001] The invention relates to the field of equipment used in the process of recovering organic matter in hydrogen chloride gas, more specifically, relates to the equipment used in the process of recovering organic matter in hydrogen chloride gas. Background technique [0002] Methane chloride, also known as methyl chloride, is a product formed when the hydrogen atoms in the methane molecule are replaced by chlorine atoms. According to the number of hydrogen replaced by chlorine on a single molecule of methane, methane chloride can be divided into monochloromethane, dichloromethane, and trichloromethane. Chloromethane and tetrachloromethane are four compounds, among which monochloromethane is a colorless gas with an ether-like odor, and the rest are colorless, transparent, and volatile liquids. Methane chloride is second only to vinyl chloride in organic products. The bulk chlorine-based products are important chemical raw materials and organic solvents. Dur...

Problems solved by technology

[0003] The existing absorption tower for absorbing hydrogen chloride is mainly composed of a tower body, a demister layer, a packing layer, a spray system, a medicine storage tank, a circulation pump, and a centrifugal fan. The bottom of the tower body enters the interior and flows upwards, and then the spray system, the storage tank, and the circulation pump cooperate with each other to spray the absorption liquid on the mixed gas in the tower body, and the absorption liquid absorbs the hydrogen chloride in the mixed gas to realize the removal of the mixed gas. The purpose of hydrogen chloride, but the absorption tower of this structure cannot continue to work, and it needs to be shut down to replace the absorption liquid after a period of use, resulting in low tail gas treatment efficiency, which limits the production efficiency of methane chloride, and when replacing the absorption liquid, need First discharge the absorption liquid in the drug storage barrel and then fill it with new absorption liquid. During this process, both releasing the absorption liquid and filling the new absorption liquid will consume a lot of time, resulting in a long downtime of the absorption tower and further reducing the treatment efficiency of the tail gas. , which further limits the production efficiency of methane chloride, so it is urgent to design a kind of equipment used in the process of recovering organic matter in hydrogen chloride gas
