Description

 The invention relates to the oil and gas industry.

 A device containing a combustion chamber with devices for supplying an oxidizing agent, fuel and water (ed. St. N 1003585, class E 21 B 43/24, 1981) is known. The disadvantage of this device is its non-transportability, since it is rigidly mounted on the wellhead.

 The closest device is a device for the production of gas and steam containing a compressor, a compressor drive in the form of a reciprocating internal combustion engine with an exhaust manifold, a water spray device made in the form of a nozzle, and an outlet pipe (ed. St. N 283123, class E 21 B 43 / 24, 1968).

 The disadvantage of this device is its low efficiency and environmental pollution by exhaust gases by an internal combustion engine.

 To eliminate the above disadvantages in a device for producing gas and steam containing a compressor, a compressor drive in the form of a reciprocating internal combustion engine with an exhaust manifold, a water injection device made in the form of a nozzle, and an outlet pipe, the compressor includes a cylinder block located at an angle to the cylinder block internal combustion engine and the same with it in the number and size of cylinders, and the pistons of the compressor cylinders are alternately connected by connecting rod mechanisms to a common crank m shaft, and in the compressor cylinder block the number of cylinders is a multiple of 6, half of these cylinders are combined in the first compression stage, the input of which is connected to the exhaust manifold and to the water injection device, 1/3 of the cylinders in the second compression stage, the rest form the third stage, the output of which communicated with the output pipe of the device.

 In FIG. 1 shows a structural diagram of a device for the production of gas; figure 2 is a side view of the device for the production of gas and steam.

 The device comprises a reciprocating internal combustion engine with cylinder block 1 and a compressor with cylinder block 2, matching the number and size of cylinders with block 1. The pistons of the compressor and engine cylinders are alternately connected by connecting rod mechanisms with a common crankshaft (not shown in Figs. 1 and 2) . The number of compressor cylinders is a multiple of 6, and half of these cylinders are combined in the first compression stage, the input of which is connected by a pipe 3 to the exhaust manifold 4 of an internal combustion engine and to a water injection device 5 made in the form of a nozzle. 1/3 of the compressor cylinders are combined into the second compression stage, the rest form the third stage, the output of which is connected to the output pipe 6. A superheater 7 is installed on the output pipe.

 A three-way valve 8 is installed in the pipeline 3, which communicates the exhaust manifold 4 and the water injection device with the atmosphere and disconnects them from the inlet of the first compressor compression stage. Between the three-way valve 8 and the inlet of the first compressor compression stage, a pipe 9 is connected, connected to the atmosphere through a check valve 10.

 The device operates as follows.

 Water is injected into the exhaust stream of the internal combustion engine coming from the exhaust manifold 4 using the nozzle 5. The mixture of exhaust gases and water through pipeline 3 enters the compressor. In the compressor, the mixture is compressed with increasing temperature. In this case, the water in the mixture evaporates partially or completely, depending on the ratio of the mass flow rates of exhaust gases and water. From the output of the third stage of compressor compression, the mixture is sent to the outlet pipe 6 through a superheater 7. During engine start-up, when it has not reached the operating mode, the mixture of exhaust gases and water through a three-way valve 8 is discharged into the atmosphere, and enters the input of the first stage of compressor compression atmospheric air through the pipe 9 through the check valve 10.

 The proposed constructive implementation of the compressor and engine cylinder blocks and their relative position allow to obtain a compact and reliable device.

 The supply of the mixture of exhaust gases with water to the inlet of the first compressor compression stage allows not only to obtain a gas-vapor mixture, but also to remove the heat stress from the compressor, which makes it possible to refuse to use a special compressor cooling system.
