Problems solved by technology

However, the separated substances are mainly large-density sand particles, light-density oil bodies and associated gas, while the separation of relatively low-density small-particle coal powder, water and coalbed methane is difficult to achieve
Although the widely used coal washing equipment can separate the coal-water mixture, it cannot separate the coalbed methane
The gas and coal-water separation devices and methods commonly used in coal mines are mainly for the separation of the injected gas and coal-water, and cannot solve the problem of separating the gas-water-coal mixture containing undesorbed coalbed methane.

Abstract

The invention discloses a separation device and a separation method for a gas, water and coal mixture. The separation device comprises a separation cabin. A feed inlet is formed in the separation cabin, a crusher is mounted on the feed inlet, a gas conveying pipe is mounted at the upper end of the separation cabin, and a gas bottle is mounted on the gas conveying pipe; a first screen is mounted inthe separation cabin, a first coal discharge pipe is mounted on the first screen, the first coal discharge pipe stretches out of the separation cabin, a vibration exciter is also mounted on the firstscreen, the vibration exciter is arranged vertically, a sound wave transducer is mounted at the lower end of the vibration exciter, a vibrating motor and an ultrasonic generator are mounted out of the separation cabin, and the vibrating motor is connected to the vibration exciter. The separation device is simple in structure, safe and reliable and suitable for separating the gas, water and coal mixture.

Description

technical field [0001] The invention relates to the technical field of mining of coal and coal bed gas, in particular to a separation device and method for a mixture of gas, water and coal. Background technique [0002] China's tectonic coal is widely developed and tectonic coal-bed methane resources are abundant. As a clean energy source, coal-bed methane has attracted widespread attention. Co-production of coalbed methane and coal by in-situ coalbed methane wells on the ground can be used as an important means for the development of structural coalbed methane. However, the coal particles and water produced during the drilling of coalbed methane wells are in a mixture state, making it difficult to effectively separate and collect gas, water, and coal, and part of the coalbed methane contained in the coal particles has been desorbed and is in the state of free gas, and part of it is still present in the pulverized coal The interior has not yet desorbed, increasing the diffi...
