1. Background and meaning

The temporary storage warehouse of waste power plant is mainly used to store waste to be incinerated. Domestic waste is piled for a long time. A large number of microorganisms in the waste release a large amount of toxic and harmful gas in the process of decomposing the waste. According to the state For unorganized emission source gas monitoring requirements and enterprise personnel safety management requirements, hazardous gas monitoring in garbage dumps is necessary and important. Existing garbage power plants mostly use fixed gas sensors installed in detection locations. The main problems are:

● The sensor is installed in an explosion-proof area, maintenance and calibration are difficult, and safety risks are high;

● Single set of area coverage is small, multiple sets of equipment deployment costs are high.

2, plan

The hazardous gas detection system of the garbage warehouse is mainly used for online monitoring of the hazardous gases in the garbage warehouse. Due to the existence of the hazardous gases in the garbage warehouse, the device used in this plan is a multi-point extraction type, and the detection instrument is placed in the In the safe area, each extraction head is distributed in the area that needs to be detected, such as the leachate channel, garbage dump area, etc., through intermittent circulation extraction to achieve multi-region sampling and intermittent monitoring of hazardous gases. This program has automatic extraction control and gas overrun Sound and light alarm, fault self-diagnosis and other functions, maintenance and calibration are simple.

3, value

● Real-time monitoring of online gas concentration to ensure safety;

● Maintenance, easy to use, reduce the cost of later operation and maintenance.
