Temperature detecting circuit for household garbage waste plastic cleavage reaction

Abstract

The invention relates to a temperature detecting circuit for household garbage waste plastic cleavage reaction. According to an existing temperature detecting system, demands for accuracy and reliability cannot be completely met. The temperature detecting circuit comprises a temperature compensating circuit module, a temperature signal amplification module, an active low-pass filtering module, an A / D conversion module and a differential processing module. A temperature sensing component is used for sensing a temperature signal and connecting the temperature signal to the temperature compensating circuit module. The output end of the temperature compensating circuit module is connected to one input end of the temperature signal amplification module. The active low-pass filtering module is connected with the output end of the temperature signal amplification module. After the process of filtering is finished, the active low-pass filtering module is connected with the input end of the A / D conversion module, and the output end of the A / D conversion module is connected with the differential processing module. The output end of the differential processing module serves as the output end of the temperature detecting circuit. The temperature detecting circuit is high in temperature detecting accuracy, strong in anti-jamming capability and low in cost.

Description

technical field [0001] The invention belongs to the technical field of signal detection and relates to a temperature detection circuit for the pyrolysis reaction of domestic waste waste plastics. Background technique [0002] In today's society, issues such as energy and environmental protection are becoming more and more prominent, and the recycling and secondary utilization of garbage have attracted more and more attention from people, and have gradually become the development direction of contemporary energy. In the process of waste treatment, temperature is an important physical quantity and one of the important parameters that need to be measured and controlled. The output, quality and energy consumption of the obtained products are directly related to the temperature. Therefore, it is of great practical significance to measure temperature accurately. [0003] In the process of garbage processing, it is necessary to send the relatively clean garbage with low water ...

AI Technical Summary

Problems solved by technology

In a high-temperature reactor, temperature measurement and control is a very important link. The accuracy of the data obtained by the traditional high-temperature ambient temperature measurement method is not high, and poor temperature control will cause some unnecessary waste to be generated during the decomposition process. products that affect the quality of the oil

Moreover, the life of the traditional temperature measuring device is not long, and the damage rate is relatively high during use.

At present, relevant detection systems have appeared on the market, but they cannot fully meet the requirements in terms of accuracy and reliability. It is very urgent to develop a high-precision, anti-interference high-temperature temperature detection system.
