A coal-to-natural gas solid waste resource recovery and reuse system

Abstract

The invention discloses a coal-based natural gas solid waste resource recovery and reuse system, which belongs to the coal-based natural gas technical field. A coal-based natural gas solid waste resource recovery and reuse system includes a recovery device and a recovery method. The recovery device includes a device box, The outer walls of both sides of the device box are fixedly connected with supporting legs, the outer wall of one side of the device box is connected with a feed pipe, and the inside of the device box is movable and installed with a screening bucket, and the top of the screening bucket is connected with a first corrugated soft The top end of the first corrugated hose is fixedly connected with a top plate, and the feeding pipe communicates with the first corrugated hose. It can realize the collection and screening of the solid waste fly ash generated during the implementation of the gas project, and the fly ash with different particle sizes after screening can be recycled and reused separately, which not only reduces the pollution to the environment, but also saves resources and saves resources. The problem that the fly ash is easy to raise dust during the collection and screening process is solved, and the health of the staff is prevented from being endangered.

Description

technical field [0001] The invention relates to the technical field of coal-to-natural gas, more specifically, to a coal-to-natural gas solid waste resource recovery and reuse system. Background technique [0002] Under the dual pressure of air pollution and the sharp increase in demand for natural gas, under the reality that there is a large gap in the supply of natural gas and China's energy structure will still be dominated by coal for a long time, and under the rigid constraint that coal must be used cleanly and efficiently, more and more of enterprises have set their sights on coal-based natural gas, hoping to find a new path of clean and efficient utilization of coal. However, during the production of clean natural gas, a large amount of "three wastes" will be produced, namely waste water, waste gas, and waste residue, which will bring heavy pressure to the ecological environment where the project is located. [0003] The waste slag during the implementation of the co...

Problems solved by technology

[0004] In fact, the landfill method does not fundamentally solve the problem of garbage pollution, but only temporarily isolates the waste so that it will not have a negative impact on the surrounding natural environment for the time being. The erosion of rainwater will lead to the leaching of waste residue or into the groundwater , which will cause water pollution and form a large amount of landfill leachate with complex components and high concentrations of harmful substances, which will increase the cost of project investment
