Abstract
The utility model discloses a coal mine underground coal bed gasification and energy-storage structure. In the structure, a gas-permeable heat insulation wall is arranged in two air current passages at intervals of 20-50cm; the thickness of the gas permeable heat insulation wall is 20-50cm; and the total area of the air ventilation holes of the gas permeable heat insulation wall is twice as large as the area of gas outlets of earth's surface. In the utility model, since the gas permeable heat insulation wall is arranged, the heat is controlled to be reserved around the bottom of a furnace so as to enable cola masses in deep part adjacent to the bottom of the furnace to be heated and distilled dryly, thereby increasing the output efficiency of coal gas, promoting the full use of energy at the same time, reducing the damage of high temperature gas to the air current passages and a pipeline system, ensuring the stability and the reliability of a production system in use, ensuring the full use of heat, and achieving the purposes of energy conservation and emission reduction.
Description
Technical field
The utility model relates to the gasification of coal mine down-hole coalbed technology, especially the gasification of coal mine down-hole coalbed stove.
Background technology
Down-hole, coal seam gasification technology is a new production technique, and so-called down-hole coal bed gasification is exactly by control device subterranean coal directly to be burnt in the down-hole, displaces highly purified coal bed gas by technical finesse then.Be gas production by becoming to mine, production technology is simple, can reduce security incident, reaches clean purpose of producing.
Gasification of coal mine down-hole coalbed generally is directly to construct coal seam gasification stove and two gas channels (air duct and gas passage) under coal mine at present, delivers air to the down-hole by air duct, by gas passage coal gas is transported to ground.Because coal discharges a large amount of heats when burning in gasification furnace, the gas temperature that furnace bottom produces is up to 1000-1200 ℃, after causing coal gas of high temperature to arrive face of land outlet, temperature is above 150 ℃, high-temperature gas is heating gas channel high temperature in the process of circulation on the way, gas channel country rock heat-resistant stability is reduced, and high-temperature gas makes ground coal gas receiving pipeline system also produce infringement to the outlet of the face of land, and a large amount of heat energy are run off to make full use of.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that existing gasification of coal mine down-hole coalbed furnace zone is come, and a kind of gasification of coal mine down-hole coalbed accumulation of energy structure is provided.
For achieving the above object, structure of the present utility model is, it comprises two gas channels, it is characterized in that, every interval 20-50cm is furnished with the breathable insulation wall one in two gas channels, and the thickness of breathable insulation wall is 20-50cm; The gross area of the air-vent of breathable insulation wall is 2 times of gas outlet, face of land area.
Good effect of the present utility model is: owing to be provided with the breathable insulation wall, heat control is retained in around the furnace bottom, makes near the furnace bottom destructive distillation of being heated of deep coal body, the coal gas output efficiency is increased; Promote that simultaneously energy makes full use of, and reduce the harm of high-temperature gas, guarantee production system reliability during use, guaranteed that heat makes full use of, reach the purpose of energy-saving and emission-reduction gas channel and pipe-line system.If it is better that two gas channels replace the exhaust result of use.
Description of drawings
Fig. 1 is an end view of the present utility model;
Fig. 2 is an A-A partial enlarged drawing among Fig. 1.
Among the figure: 1,4-gas channel, 2-breathable insulation wall, 3-gasification furnace, 5-refractory material, 6-air-vent.
The specific embodiment
Below in conjunction with Fig. 1 the technical solution of the utility model is described.
Fig. 1 is an end view of the present utility model, as can be seen from the figure, energy storage equipment of the present utility model is arranged on two gasification tunnels 1 and 4 of down-hole coal bed gasification furnace 3, every interval 20-50cm builds breathable insulation wall 2 by laying bricks or stones one, the breathable insulation wall construction as shown in Figure 2, it is built by laying bricks or stones with refractory material 5 and forms, and its thickness is 20-50cm; The gross area of the air-vent 6 of breathable insulation wall 2 is 2 times of gas outlet, face of land area.
