Embodiment Construction
[0010] A process for recovering and utilizing carbon dioxide in beer production, characterized in that it includes a gas purification unit, a gas storage and compression unit, a drying unit, an adsorption unit, a refrigeration compression unit and a recycling unit connected in sequence; the gas purification unit Including: demister and scrubber; the fermentation gas containing carbon dioxide enters the demister which is fed with water, removes the foam in the gas and enters the scrubber. The scrubber adopts two-stage double tower washing, and the first stage uses permanganic acid Potassium is used as detergent, potassium permanganate solution is sprayed down from the top of the tower, carbon dioxide is convected upward from the bottom of the tower to remove aldehydes in the gas, and sodium bicarbonate is used as detergent in the second stage of washing to remove acids; After the washing process is completed, it enters the gas storage and compression unit through the steam-water...

The invention relates to a carbon dioxide recovery and utilization process, and specifically relates to a recovery and utilization process of carbon dioxide in beer production. The invention belongs to the technical field of waste gas treatment. The process comprises a gas purification unit, a gas storing and compression unit, a drying unit, an adsorption unit, a refrigeration compression unit, and a reutilization unit. Silica gel is adopted as a drying agent in the drying unit. Double-tower drying is carried out, and water is removed, such that qualities of products such as beer are prevented from being affected by water contained in carbon dioxide. The absorption unit adopts active carbon and synthesized sodium-type zeolite as absorption agents, such that volatile substances and water-insoluble undesirable gas are removed. The refrigeration compression unit aims at converting gas into easy-storage liquid. The reutilization unit is used for gasifying the liquid-state carbon dioxide, and the carbon dioxide gas can be recycled in beer filling. According to the invention, a chemical-physical combined method is adopted for purifying and recovering carbon dioxide. The recovered carbon dioxide has high purity and low energy consumption, and can be used in beer filling in beer factories. Therefore, substantial economic and social benefits are provided.
Description
technical field [0001] The invention relates to a process for recovering and utilizing carbon dioxide, in particular to a process for recovering and utilizing carbon dioxide in beer production, and belongs to the technical field of waste gas treatment. Background technique [0002] With the increasing development of the economy, energy and the environment have become the focus of global attention. Both developed and developing countries regard sustainable development strategy as an inevitable choice. [0003] At present, the greenhouse effect produced by the massive emission of greenhouse gases has brought many negative effects on natural conditions and human living conditions. For example, rising temperatures, rising sea levels and frequent severe weather. Therefore, the climate change caused by the "greenhouse effect" has become a global hot environmental issue, which has attracted more and more attention from all countries in the world. Among them, the main gas compone...
