Abstract

The invention discloses a steam generator with a coiled tube and heat transfer sheets. The steam generator is structurally characterized in that two seal heads are spliced to form an inner container, the coiled tube is arranged under the heating inner container, the heat transfer sheets are arranged inside the inner container, a first pressure gauge and a first safety valve are connected with a water inlet in the periphery of a steam generator body, and a second pressure gauge, a second safety valve and a steam valve are connected to a steam outlet in the periphery of the steam generator body; a support is arranged on one side of the inner container and is supported by a first rib and a second rib. During operation, the coiled tube is heated, saturated steam is generated by water in the coiled tube, rises along the coiled tube and reaches the top of the inner container, and saturated steam can be generated by water which continuously flows into the coiled tube, so that circulation is implemented; the heat transfer sheets are arranged inside the inner container, so that the heat transfer area can be increased, heat can be quickly and efficiently transferred, a heat-insulation steam tube is connected with the outside of the steam outlet, so that the steam required by operation can be outputted. The steam generator has the advantages that the steam generator is simple in structure, convenient to operate and high in efficiency, is safe and reliable and is widely applicable to steam drilling machines in high-altitude and glacial environments, and problems of long heating time, low drilling depth and efficiency, heavy device weight, large size and the like of an existing steam generator of a steam drilling machine can be solved.

Description

Coil pipe adds heat transfer chip steam generator

Technical field

The invention belongs to a kind of steam raising plant of steam rig, is that a kind of coil pipe that is applicable to the adverse circumstances such as high height above sea level and glacier adds heat transfer chip steam generator specifically.

Background technology

At present the steam generator (also claiming inner bag) for high height above sea level region steam rig is generally fire-tube type, and for cylindrical, the flame of heating is comformed in multi-heating-pipe and passed through, and is liquid between heating tube; There is following problem in the steam generator of the type: energy consumption is large, and larger to glacier environment pollution, the thermal efficiency is low, the heat time is long, device is heavy, and volume is large, bores the depth, and has certain potential safety hazard.Thereby limited occasion and the scope of its use, limited greatly the related scientific research work in high height above sea level region simultaneously.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of easily and fast, the coil pipe that efficient, simple in structure, volume is little, safe adds heat transfer chip steam generator.

Realizing the technical scheme that object of the present invention adopts is:

A kind of coil pipe adds heat transfer chip steam generator ,comprise coil pipe, end socket, support, inner bag, heat transfer sheet, water inlet, steam (vapor) outlet or be delivery port, the first Pressure gauge, the second Pressure gauge, the first safety valve, the second safety valve and steam valve.Inner bag is spliced by two end sockets, heating inner liner below is provided with coil pipe, inner bag inside is provided with heat transfer sheet, water inlet and steam (vapor) outlet (or being delivery port) lay respectively at the right and left of inner bag, the water inlet of steam generator periphery is connected to the first Pressure gauge and the first safety valve, and steam (vapor) outlet is connected to the second Pressure gauge, the second safety valve and steam valve; Inner bag one side is provided with support, and support is supported by the first muscle and the second muscle.

The beneficial effect of advantage of the present invention and generation is:

1, generator inner bag is directly spliced by two end sockets, adopts the welding manner of complete penetraction and fusion in welding, and security is increased dramatically.

2, the method that the present invention adopts heating to be placed in inner bag bottom coil pipe increases the heating surface area of inner bag, and inner bag inside is provided with heating plate simultaneously, has further increased heating surface area, can realize fast, efficiently produce the object of steam.Water inlet of the present invention and steam outlet all configure safety valve and Pressure gauge simultaneously, and this double safety valve and the two manometric scheme of configuring on generator, guarantees steam rig work safety under high height above sea level and glacier environment.

3, the present invention is simple in structure, easy to operate, safe and reliable, and efficiency is high, and volume is little, can be applicable to widely the steam rig of high height above sea level and glacier environment.

The specific embodiment

Below in conjunction with accompanying drawing, by embodiment, the present invention will be further described in detail:

As Figure 1-3, a kind of coil pipe adds heat transfer chip steam generator ,comprise coil pipe 1, end socket 2, support 3, inner bag 4, heat transfer sheet 5, water inlet 6, steam (vapor) outlet, or be delivery port 9, the first Pressure gauges 11, the second Pressure gauge 14, the first safety valve 12, the second safety valve 13 and steam valve 15.Inner bag 4 is spliced by two end sockets 2, and coil pipe 1 is placed in the bottom of inner bag 4, and connects inner bag 4 upper and lower sides, and inner bag 4 inside are connected with heat transfer sheet 5.Water inlet 6 and steam (vapor) outlet (or being delivery port) 9 lays respectively at the right and left of inner bag, the water inlet 6 of steam generator 10 peripheries is connected to the first Pressure gauge 11 and the first safety valve 12, steam (vapor) outlet or be connected to the second Pressure gauge 14, the second safety valve 13 and steam valve 15 for delivery port 9, inner bag 4 one sides are provided with support 3, and support 3 is supported by the first muscle 7 and the second muscle 8.

Before work, from water inlet 6 injected waters of coil pipe 1, during work, by high mountain gas firing heat(ing) coil 1, produce saturated vapor and along coil pipe 1, rise to the top of inner bag 4, water enters coil pipe 1 again, continue heating, at the continual generation saturated vapor of coil pipe 1, realize circulation, in the course of work, the heat transfer sheet 5 being connected with inner bag 4, the heating surface area of quickening and increase inner bag 4, improves heat transfer efficiency, on steam (vapor) outlet 9, can connect heat-insulating hose and drilling pipe, i.e. the steam of exportable steam rig need of work.

After steam rig is finished using, from delivery port 9, residue water in steam generator 10 is discharged, during inoperative, steam generator 10 inside can not water, to prevent bursting by freezing.
