Measuring method for mixed gas under complex working condition

Abstract

The invention relates to a measuring method of gas energy resources of industrial enterprises, in particular to the measuring method of mixed gas under complex working condition. The technical proposal is that: under the condition of mixing blast furnace gas and coke oven gas, density compensation is carried out by applying computer software to compensate a mathematical model according to a thermal value and taking the thermal value as one of the parameters on the basis of the original temperature and pressure compensation, thus obtaining the accurate measuring value of the mixed gas; the adoption of the co-existence of a plurality of communication ways, and the application of computer process control technology and thread parallel technology can effectively improve the stability and reliability of system operation. The method can cause the measurement of the mixed gas to be more scientific and close to the true value, solves the problem of the accurate measurement of mixed gas medium which is greatly influenced by the thermal value under the condition of complex working condition, and can be widely applied to heavy industry enterprises using the mixed gas, thus causing the measurement and the operation of the mixed gas to be more reasonable and effectively guiding the production.

Description

Technical field [0001] The invention relates to a metering method of gas energy in industrial enterprises, in particular to a metering method of mixed gas under complex working conditions. Background technique [0002] At present, in the production of industrial enterprises, gas energy measurement is an information-based energy measurement and acquisition system, which uses on-site primary and secondary instruments, communication networks and data acquisition computers to form a metering acquisition system for acquisition and measurement. However, the working conditions of heavy industrial enterprises are relatively complicated, and the measurement results of the above-mentioned metering systems are not accurate, so they cannot effectively guide production; (Blast furnace gas mixed with coke oven gas) The density of the medium is easily affected by the calorific value. Traditional measuring instruments only have temperature and pressure compensation. The measured value and t...

Problems solved by technology

However, the working conditions of heavy industrial enterprises are relatively complicated, and the measurement results of the above-mentioned metering systems are not accurate, so they cannot effectively guide production; (Mixed blast furnace gas and coke oven gas) The density of the medium is easily affected by the calorific value. Traditional measuring instruments only have temperature and pressure compensation. The measured value and the real value fluctuate greatly, and the measurement accuracy is not high.

In addition, the gas metering communication network adopts a single communication method, and the scalability of the system is not strong. Data collection and storage are carried out in an unattended state, and data collection and storage are prone to failure when affected by system factors, which is not suitable for complex work. The actual needs of gas metering under environmental conditions
