Abstract
The utility model belongs to the technical field of coal underground gasification equipment, particularly an electric-melting and panel turnover gas-injecting point controller. The controller is composed of a four-way pipe, a panel turnover A, a panel turnover B, a panel turnover C, an electric control heating wire, a low-melting metal pretension binding rod and a rotary shaft accommodator. The panel turnover A and the panel turnover B are fixed on a by-pass path end port of the four-way pipe via the low-melting metal pretension binding rod, and the rotary shaft accommodator is arranged at the pipe wall at both sides of the centerline at one side of the down stream of a main path of the four-way pipe. The panel turnover C is arranged on the rotating shaft accommodator at one side of the down stream of the main path of the four-way pipe, and the electric control heating wire winds the low-melting metal pretension binding rod. The utility model is combined with separation controlling gas injection process, which can increase controllability and stability of the underground gasification process and can automatically control a gas injection point to rise. The gas injection point is caused to rise with the rise of a gasification working surface so as to effectively control the gasification process.

Technical field
The utility model belongs to the coal underground gasification technology apparatus field, and particularly a kind of electric smelting turnover plate type gas injection point control device is applicable to underground coal gasification(UCG) control gas injection point gasifying process.
Background technology
The method of control gas injection point is less in the underground coal gasification(UCG) process at present, in shaft underground gasification process is arranged, someone proposes the pipe of placement different length in gasification tunnel and controls the gas injection point, and also the someone proposes to realize the gas injection point control with the method for explosion pipeline.But the former consumption of materials is big, and the latter was lost efficacy because of explosive or had unsafe factor, and is difficult to realize that it is very necessary therefore inventing a kind of safe and reliable gas injection point control device.
Summary of the invention
The purpose of this utility model provides a kind of electric smelting turnover plate type gas injection point control device that is applicable to the coal underground gasification furnace.
The utility model is made up of cross, turnover panel A, turnover panel B, turnover panel C, automatically controlled heater strip, low-melting-point metal pretension bar, axis of rotation adjuster; Turnover panel A and turnover panel B are fixed on the cross bypass port by low-melting-point metal pretension bar, the axis of rotation adjuster is installed on the center line both sides tube wall of cross primary path downstream one side, turnover panel C is installed on the axis of rotation adjuster of cross primary path downstream one side, can rotate, automatically controlled heater strip installs around on low-melting-point metal pretension bar.
On the four-way tube wall at described turnover panel C place, the sealing position-arresting ring is installed, guarantees that turnover panel C can only revolve the effect that turn 90 degrees and play the sealing primary path;
Along the center line both sides axostylus axostyle is installed at described turnover panel C, it inserts in the axle sleeve of axis of rotation adjuster;
At primary path and bypass port flange is installed all at described cross;
At described turnover panel A and turnover panel B and be fixed and accompany the fire prevention cushion between the cross bypass port, sealing bypass port prevents that gas from flowing out;
One stainless steel wire backguy is installed on described turnover panel C, and the other end of backguy is fixed on the turnover panel B, drives turnover panel C by the steel wire backguy and rotate when turnover panel B falls.
The beneficial effect that the utility model reaches is: electric smelting turnover plate type gas injection point control device is in conjunction with separating the control gas injection technology, the controllability and the stability of underground gasification process have been increased, can control on the gas injection point automatically and move, make the gas injection point follow gasification face on move and on move, thereby realized effective control to gasification.
