Embodiment Construction

[0047] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] Such as figure 1 As shown, the two-dimensional horizontal section of the landfill includes production wells and monitoring wells. The monitoring wells are arranged every 20m, and a production well is arranged in the middle of the square area formed by the four monitoring wells. The wellhead of the production well is controlled by a valve, providing With a certain negative pressure of pumping, the landfill gas is extracted by using the pressure difference and sent to the generator room for biogas power generation. Furthermore, flow monitoring sensors and valve opening controllers are installed on the production wells for regular monitoring of landfill gas flow data and control of valve opening. The monitoring well has a smaller pipe diameter than t...

Abstract

The present invention discloses a landfill gas acquisition optimization control system based on cloud. The system comprises a data acquisition terminal, a control terminal and a cloud server. The system is able to transmit the production data and the monitoring data in the landfill operation process through a GPRS network to a cloud server, and complete the optimization of inversion calculation and production strategy of the landfill model parameters in the cloud server so as to display the data at the front end of the site for visualization and emit the decision data to the control terminal for gas production optimization control. The landfill gas acquisition optimization control system based on cloud is able to effectively improve the landfill gas acquisition management level, reduce the environment problem caused by discharging landfill gas, enhance the usage rate of the landfill gas (methane) which is taken as clean energy, and relieve the energy crisis.

Description

technical field [0001] The invention belongs to the technical field of waste management and Internet of Things industrial control, and specifically relates to a cloud-based landfill gas collection optimization control system. Background technique [0002] Human society has entered an era of rapid development, and people's production and domestic waste is also increasing day by day with the pace of social development. At present, landfill is still the main way to deal with waste at home and abroad, supplemented by incineration. The landfill-based treatment mode saves a lot of process costs, but it also brings many troubles, such as occupying a large amount of land, secondary pollution of landfill gas and leachate, and so on. Landfill gas is a by-product of domestic waste landfills, and a large amount of landfill gas (CH 4 and CO 2 Mainly), they are the main greenhouse gases, which will exacerbate global climate change. In addition, methane is a clean energy. In the first ye...
