Carbon dioxide automatic control recycling device for fermentation tank

Abstract

The invention relates to a carbon dioxide automatic control recycling device for a fermentation tank. The carbon dioxide automatic control recycling device is characterized by comprising a recycling device and an automatic control device; the recycling device comprises a bubble trap, a sealing tank, a washing tower, a first steam-water separator, a CO2 compressor, a cooler, a second steam-water separator, a filter, a condenser and a CO2 storage tank, the automatic control device comprises a control system, a liquid level meter, a compressor pressure sensor, a CO2 concentration detector, a CO2storage tank stored pressure sensor and an alarm apparatus. The carbon dioxide automatic control recycling device for the fermentation tank carries out full-automatic control and monitoring, can givean alarm to remind staff to carry out processing operation, recycle CO2, lower the CO2 exhaust amount and have a social significance in promoting sustainable development, improving the environment, increasing economic benefit and the like.

Description

technical field [0001] The invention relates to a recovery device in the field of brewing, in particular to an automatic control recovery device for carbon dioxide used in a fermenter. Background technique [0002] The rapid development of the economy, for the CO 2 Recycling offers a broad market. Currently, CO 2 There are two main directions for the utilization of CO2, one is the chemical industry, the other is the food industry, the former is for CO 2 The quality requirements of the latter are slightly lower, and the latter have higher requirements and must meet food-grade CO 2 National standards for the food industry CO 2 It can be used as an aerating additive for beer and carbonated beverages, as well as a vegetable preservative without polluting food. During the production of alcohol by fermentation methods such as liquor and beer, a large amount of CO is always associated 2 Gas, the content is between 90% and 98%, which is a good high-concentration CO 2 Gas sourc...

AI Technical Summary

Problems solved by technology

[0003] CO produced in liquor and beer production 2 It is widely used in the food industry, and the physical absorption method has become a CO2 method because it is not corrosive to equipment. 2 A method commonly used for recovery has large absorption capacity, easy regeneration, low energy consumption, and less absorbent consumption, but the separation effect is low and the cost is high. Due to the CO used in the food industry 2 The purity requirement is higher, in CO 2 The recycling process requires manual operation and control, and the labor cost is relatively high, so higher requirements are placed on the recycling equipment
