Problems solved by technology

[0004] The disadvantage of the existing technology is that in the process of use, due to the different factors such as the properties, pipe diameters and stress conditions of multiple pipes, the bending and tensile loads on different pipes will be different, so that The deformation range of different pipes is different, which causes the inner pipe to wear the outer pipe, which affects the fluid transportation, or the pipe with large deformation forces the parallel pipe with small deformation to tear, all of which have a negative impact on the normal operation of the pipe

Embodiment Construction

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] As shown in Figure 1, a tube bundle device for underground coal gasification provided by an embodiment of the present invention includes a fixing part 2 and two continuous tubes 1, and the two continuous tubes 1 are connected to the fixing part 2 in parallel , the axes of the two continuous pipes 1 are arranged in parallel, and there is a predetermined gap between the outer walls of the two continuous pipes 1 . Such as Figure 1A and 1C As shown, the radial dimensions of the two continuous pipes 1 are the same, such as Figure 1B As shown, the radial dimensions of the two continuous pipes 1 are different. Correspondingly, except for the radial dimension, the wall thickness, material, and shape of the two coiled tubing 1 can be the same o...

Abstract

The invention discloses a flux tube device and flux tube conveying device for underground coal gasification. The flux tube device comprises at least two coiled tubings and further comprises a fixing member. A number of coiled tubings are connected in parallel to the fixing member, the axes of the coiled tubings are arranged in parallel, and a predetermined gap is reserved between the outer walls of any two adjacent coiled tubings. According to the flux tube device and flux tube conveying device for the underground coal gasification, the coiled tubings are arranged in parallel, and the predetermined gap is reserved between the adjacent coiled tubings, so that influences on other coiled tubings are reduced or even eliminated when different coiled tubings are deformed in different amplitudes,thereby reducing or even eliminating negative effects of normal operations.

Description

technical field [0001] The invention relates to underground coal mining technology, in particular to a bundle tube device and a bundle tube conveying device for underground coal gasification. Background technique [0002] Underground coal gasification technology is a technology that injects gasification agent directly into the original underground coal seam for thermochemical conversion reaction to produce coal gas or synthesis gas. In order to complete the underground coal gasification, it is necessary to drill a series of boreholes connecting the surface and the coal seam, or to drill boreholes in the coal seam, such as inlet boreholes, gas outlet boreholes and gasification channels. It is necessary to transport different types of substances through drilling, or install a series of equipment, such as transporting different types of gasification agents: air-oxygen, oxygen-carbon dioxide, oxygen-water vapor, oxygen-nitrogen, oxygen-water, etc., installation Different equipm...
