1. Background

Solid waste temporary storage, mainly, is used to store garbage to be incinerated. The garbage stacked for a long time, a large number of microorganisms will release a large amount of toxic and harmful gases in the process of decomposing the garbage.

According to the state's requirements for unorganized emission source gas monitoring and enterprise personnel safety management requirements, hazardous gas monitoring in garbage warehouses is necessary and important. The existing temporary storage warehouses mostly use fixed gas sensors installed in the detection position. The main problems are:

● The sensor is installed in an explosion-proof area, it is difficult to maintain and calibrate, and the safety risk is high;

● Single set has limited coverage, while multiple sets of equipment are costly.

2, plan

The hazardous gas detection system for garbage storage is mainly used for online monitoring of hazardous gases in the garbage storage. Due to the hazardous gases in the garbage storage, the device adopted in this program is a multi-point extraction type, and the detection instruments are placed in a safe area. The extraction heads are distributed in the areas that need to be detected, such as the leachate channel, the garbage dump area, etc., through intermittent cycle extraction to achieve multi-point sampling and intermittent monitoring of hazardous gases. This solution has automatic extraction control, gas over-limit sound and light alarm, with functions such as fault self-diagnosis,easy maintenance and calibration.

3, value

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

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