Abstract
Description
L'invention concerne à titre de produit industriel nouveau, un flexible pour le forage thermique de galeries horizontales dans des veines de charbon, en vue de la gazeification sauter- raine. Elle est caractdrisée par le fait, que le flexible est tubulaire, expansible, se met en place à partir de la surface du sol en le déroulant d'un tambour, qu'il avance en rampant et projette vers l'avant un mélange d'oxygène et vapeur d'eau sur une veine de charbon qu'il creuse en produisant du gaz à l'eau. The invention relates, as a new industrial product, to a hose for the thermal drilling of horizontal galleries in coal seams, for the purpose of earth gasification. It is characterized by the fact that the hose is tubular, expandable, is put in place from the surface of the ground by unrolling it from a drum, that it advances by crawling and projects a mixture of oxygen and water vapor on a coal seam which it digs while producing gas with water.
Le flexible fonctionne en deux versions. En marche avant, s'il est retire après un certain parcours, la galerie creusée peut titre un collecteur. Si la galerie creusée débouche sur un collecteur, dès que celui-ci est intercepté, on peut le faire fonctionner en rétro et produire une gazéification à haut rendement. L'oxygène débouche pur du flexible et la vapeur d'eau arrive extérieurement à l'extrêmité avant du flexible
Al'encontre de usage précédent, les gaz issus de la réaction prennent un direction opposée à celle du flexible et il n y a pratiquement pas derpfoblême de température
Une réalisation sous forme d'un dessin est annexé au présent mémoire. La figure l,est la coupe longitudinale du flexible. La figure 2, représente le flexible dans sa disposition au cours du fonctionnement.The hose works in two versions. In forward motion, if it is removed after a certain route, the dug gallery may be a collector. If the dug gallery leads to a collector, as soon as it is intercepted, it can be operated retro and produce a gasification with high efficiency. The pure oxygen comes out of the hose and the water vapor comes out to the front end of the hose
Unlike previous use, the gases from the reaction take an opposite direction to that of the hose and there is practically no temperature problem.
An embodiment in the form of a drawing is annexed to this memo. Figure l is the longitudinal section of the hose. Figure 2 shows the hose in its arrangement during operation.
En référence au dessin, l'organe de base du dispositif est une chambre tubulaire à section en couronne (1). Afin d'être expansible, l,etérieur et l'exérieur sont réalisés en tôle on dulie longitudinalement. Les embouts des extrëmités (2), sont fixés aux embouts contigus par des manchons filetés (3). L'ex- pansion des chambres est limitée par des cibles intérieurs (4), accrochés à leurs embouts respectifs. Selles communiquent par un conduit (5), situé dans les embouts. Une vanne (6), disposée sur chaque conduit, permet l'isolation ou la mise en communication des chambres.Les vannes sont commandées pneumatiquement par la tubulure (7), disposée en hélice dans la canalisation centrale (8), agissant par barres tubulaires concaves, plissées sur le côté interne (9) Un étranglement près de chaque branehement (10), conjointement avec la capacité de chaque tronçon de tube, échelonnera le fonctionnement des vannes pour la mise sous pression et l'expansion des chambres tubulaires. With reference to the drawing, the basic member of the device is a tubular chamber with a crown section (1). In order to be expandable, the inside and the outside are made of sheet metal which is longitudinally cut. The end caps (2) are attached to the adjoining end caps by threaded sleeves (3). The expansion of the chambers is limited by internal targets (4), hooked to their respective ends. Saddles communicate through a conduit (5), located in the end caps. A valve (6), arranged on each conduit, allows the isolation or the communication between the chambers. The valves are pneumatically controlled by the tubing (7), arranged helically in the central pipe (8), acting by tubular bars. concave, pleated on the internal side (9) A constriction near each branehement (10), together with the capacity of each section of tube, will stagger the operation of the valves for pressurizing and expanding the tubular chambers.
La canalisation centrale (8), amène l'oxygène et la sapeur d'eau de l'estrtmitd arrière (11) à l'extremité avant, d'oh ils sont projetés sur le charbon par la lance (12). Slle loge d'autre part une canalisation d'eau (13), pour le refroidissement du flexible et éventuellement produire de la vapeur d'eau, également disposée en hélice. L'eau est déversée dans l'estrtmité avant du canal central et à l'extérieur par des orifices (14), à travers les embouts. Pour la marche en rétro, la chambre tubulaire de l'extrmité avant, de mtme que la tubulure (7), sont reliées chacune à l'arrière par une tubulure indépendante. The central pipe (8) brings oxygen and the water sapper from the rear estrtmitd (11) to the front end, from where they are projected onto the coal by the lance (12). On the other hand, it houses a water pipe (13), for cooling the hose and possibly producing water vapor, also arranged in a helix. The water is poured into the front section of the central channel and outside through orifices (14), through the nozzles. For retro operation, the tubular chamber of the front end, as well as the tubing (7), are each connected at the rear by an independent tubing.
Un aménagement sera apporté au puit (15). A l'angle vif qu'il forme au forage avec la veine de charbon (16), on substituera un tronçon de puit courbe de 900, (17). An adjustment will be made to the well (15). At the sharp angle it forms when drilling with the coal seam (16), a section of curved well of 900, (17) will be substituted.
Pour la mise en marche, ltextrtmitd avant du flexible est engagée dans le puit, l'avance s'effectuant par déroulement. A l'approche du charbon, on y met le feu et la lance (12), projette vers l'avant le mélange oxygène-vapeur d'eau. Ces gaz, ainsi que l'eau et les gaz moteurs sont introduits dans le flexible à l'ex- trtmité arrière (11), par un raccord tournant, branché sur un pivot central distributeur. For start-up, the front hose outlet is engaged in the well, the advance being carried out by unwinding. When coal is approached, it is set on fire and the lance (12) projects the oxygen-water vapor mixture forward. These gases, as well as the water and the engine gases are introduced into the flexible hose at the rear end (11), by a rotary connector, connected to a central distributor pivot.
L'avancement du flexible se fait en deux temps. Au premier temps, on laisse descendre une certaine longueur de flexible dans le puit et il se produit une compression du flexible au pied du puit. Au deuxième temps, la tubulure (7) est mise sous pression. The advancement of the hose is done in two stages. At first, a certain length of hose is allowed to descend into the well and compression of the hose occurs at the foot of the well. Secondly, the tubing (7) is pressurized.
selle déclanche graduellement l'ouverture des vannes (6) et lamise sous pression des chambres tubulaires de l'arrière vers l'atant. Une uniformisation de leur longuenr s'effectue ainsi et la quantité comprimée au pied du puit, est ports d l'avant où sa détente produit un avancement. saddle gradually triggers the opening of the valves (6) and pressure lamination of the tubular chambers from the rear to the front. Standardization of their length is thus effected and the quantity compressed at the foot of the well is carried forward where its expansion produces advancement.
Pour la marche en rétro, les commandes sont inversées. 0E met par les moyens énoncés plus haut les chambres tubulaires en dépression de l'avant vers l'arrière, puis en surprsBsion dans le meme ordre. L'acquis du recul de l'extrêmité avant de la première chambre est graduellement transmis jusqu'au pied du puit où il est résorbé par une remontée par traction. For reverse operation, the controls are reversed. 0E puts by the means mentioned above the tubular chambers in depression from front to rear, then in supersession in the same order. The experience of the receding of the front end of the first chamber is gradually transmitted to the foot of the well where it is absorbed by a rise by traction.
Bien entendu l'invention ne se limite pas au mode de réalisation représenté et décrit et au dessin annexé à titre d'exem- ple, elle peut varier de forme, de modèle sans que soit altéré le principe de l'invention, le but étant de rester dans le cadre de l'idée nouvelle, objet du présent brevet. Of course, the invention is not limited to the embodiment shown and described and to the attached drawing by way of example, it can vary in shape, in model without the principle of the invention being altered, the aim being to remain within the framework of the new idea which is the subject of this patent.
