The Beer Fermentation Carbon Dioxide Recovery And Vaporization System Improvements Design

The beer production is a traditional industry in our country, with the development of the national economy and the improvement of people’s life, the Chinese beer industry has been an unprecedented development. The technology and equipment production enterprise most beer in China is backward, low degree of automation. To improve the level of automation of beer production, enhance the comprehensive strength of China’s beer industry is a crunch time research topic, at the same time, with the increasingly fierce market competition, the beer industry showing a toward energy saving, consumption and efficiency of development.Carbon dioxide compressor fermentation carbon dioxide recovery system Tsingtao beer factory two during operation to the cooling water cooling, the cooling water system in summer is not up to the requirements, affecting the efficiency of carbon dioxide recovery system. In the pure liquid carbon dioxide prepared by steam heating vaporization vaporizer can supply for use.To solve the above two issues, enterprises with carbon dioxide heat absorption process for the transformation project of carbon dioxide cooling water cooling. Topic will be fermented transformation recovery and vaporization system carbon dioxide into equipment and electrical control transformation in two parts:equipment mainly includes the installation of pipelines and a carbon dioxide vaporization heat exchange coil; electrical control transformation mainly for the use of PLC according to the temperature of cooling water and carbon dioxide vaporizing temperature switch the valve, thus saving cooling water system of ammonia refrigeration power and consumption saving carbon dioxide vaporization process steam, energy-saving benefit is considerable.Programmable logic controller (PLC) in various fields as the automatic control device of modernization has been widely used in industrial enterprises, is the intelligent control of the essential equipment in the production process automation. This design uses a Panasonic electrical FP0C14type PLC, display and the Panasonic GT32touch screen to realize state system operation.Mainly includes: Design of carbon dioxide energy-saving circulation system:liquid carbon dioxide from the equipment cooling water absorption of heat steam cooling, and decrease the temperature of cooling water, reduce the refrigeration by ammonia; at the same time saving carbon dioxide vaporization of steam required.Design and installation of PLC automatic control system, control program written, the realization of the valve switch control, safety protection, sensor data acquisition, data processing, process control, touch screen operations display content. Preparation of touch screen operation interface, realizing the hand, automatic carbon dioxide vaporizer switching operation. Recent operational data storage, alarm information, for the analysis of data and state trackingThe innovation of this research mainly includes:1, carbon dioxide vaporizing most is through the steam heating method, and less by way of the air heat of vaporization. Utilization of carbon dioxide compressor cooling water vaporization in beer factory is the first.2, write the PLC control program with a touch screen and man-machine interaction, display and operation control program running state. It has the advantages of simple operation, convenient, natural, human-computer interaction, say without mincing words etc..
