On-line monitoring system for anaerobic reactor

Abstract

The invention discloses an on-line monitoring system for an anaerobic reactor. The on-line monitoring system comprises a gas sensor, a gas trigger, a counter, a data collecting card and a computing device, wherein the computing device is provided with detection software, the gas sensor is arranged at a gas outlet of the anaerobic reactor, the gas trigger is communicated with the gas outlet of the anaerobic reactor, the counter is connected with the gas trigger, the data collecting card is respectively connected with the counter and the gas sensor, and the computing device is connected with the data collecting card. The gas sensor and the counter can transmit the collected data into the data collecting card, and the data collecting card can send the obtained data into the computing device, so the manual recording is not needed during the operation of the system. The system can be always in the sampling state, and the manual regulation is not needed in the midway, so the sampling frequency is high. The system has the advantages that structure is simple, the manufacture cost is low, and in addition, the specialty requirement on an operator is not high. Therefore, the on-line monitoring system has the advantages that the structure is simple, the manufacture cost is low, the sampling frequency is high, the operation is simple, and the like.

Description

technical field [0001] The invention relates to the field of detection instruments for anaerobic reactors, in particular to an on-line monitoring system for anaerobic reactors. Background technique [0002] Anaerobic biotechnology is widely used in many fields of sewage treatment sludge digestion. It is a mature and effective environmental protection technology. However, there are many problems in the operation of the anaerobic bioreactor in the actual operation of the factory. Affected by various operating parameters such as water, it is easy to acidify and cause the operation of the anaerobic reactor to collapse, so the monitoring of various operating parameters inside the anaerobic reactor is extremely important. The biochemical reaction process inside the anaerobic reactor is relatively complex, and there are many parameters that have index significance for the operating status of the reactor. Only by comprehensively measuring multiple parameters of the gas-liquid phase ...

AI Technical Summary

Problems solved by technology

[0004] The gas chromatograph is not only expensive, but also the operation and maintenance of the gas chromatograph is complicated, and the professional quality of the operator is required to be high. In addition, the staff needs to be adjusted every certain time, so the sampling frequency of the gas chromatograph is relatively low; The flowmeter only displays the current gas production rate, but cannot store the historical records of the gas production rate in real time, often relying on the operator to record manually
