Technical Field

The utility model relates to a CNG decompression submergence formula burning technical field specifically is a CNG decompression submergence formula burning heat transfer integrative device.

Background

At present, in a CNG pressure reducing station, two modes of hot water (steam) heat exchange or electric heat exchange are mainly adopted. The hot water heat exchange cost is low but the limiting factors are more, a hot water (steam) heat source and the temperature of the heat source are required to meet the process heat exchange requirement nearby, and when CNG pressure reduction is required by many users, the heat source temporarily does not operate or the heat source temporarily does not need to carry out CNG pressure reduction during operation, and the heat source cannot immediately meet the heat requirement required by CNG pressure reduction. And a heat supply pipeline between a heat source and the pressure reducing device is also required to be established, so that the control is complicated and manual guard is required. The electric heat exchange can meet the requirements of temperature and continuity, but the use cost is high and a large electric load margin is required nearby.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: including the operation box, install snakelike heat exchange tube of arranging in the operation box, the heat exchange tube both ends are stretched out through the operation box respectively, inlet and liquid outlet have been seted up on the operation box, the operation box intussuseption is filled with the conduction oil, the through-hole has been seted up to the wall under the operation box, the cartridge has the combustor on the through-hole, heat exchange tube one end is the import, first control valve and first relief pressure valve are installed to the heat exchange tube other end, and are connected with the combustor, the cartridge has first calandria on the heat exchange tube, install second control valve and second relief pressure valve on the first calandria.

Preferably, the upper wall surface of the operation box body is provided with a smoke outlet.

Preferably, the operation box body is provided with a liquid inlet pipe and a liquid outlet pipe which extend out of the operation box body, and the liquid inlet pipe and the liquid outlet pipe are respectively provided with a second control valve.

Advantageous effects

The utility model provides a CNG decompression submergence formula burning heat transfer integrative device. The method has the following beneficial effects: the decompressed natural gas is used as fuel, heat generated by combustion of the natural gas is transferred to heat conduction oil in a shell pass of the device as much as possible in an immersed combustion mode through a combustor, and the heat conduction oil transfers the heat to CNG in a tube pass, so that the purpose of process heat exchange is achieved. And the flue gas generated after the natural gas is combusted and the heat transfer oil are discharged out of the device after heat exchange, and the CNG is converted into low-pressure natural gas after process heat exchange and pressure regulation and is continuously supplied to downstream users and burners.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a CNG decompression submergence formula burning heat transfer integrative device, including operation box 1, install snakelike heat exchange tube 3 of arranging in the operation box 1, 3 both ends of heat exchange tube stretch out through operation box 1 respectively, inlet and liquid outlet have been seted up on the operation box 1, operation box 1 intussuseption is filled with conduction oil 4, the through-hole has been seted up to operation box 1 lower wall face, the cartridge has combustor 5 on the through-hole, 3 one ends of heat exchange tube are the import, first control valve and first relief pressure valve are installed to the 3 other ends of heat exchange tube, and be connected with combustor 5, the cartridge has first calandria 6 on the heat exchange tube 3, install second control valve and second relief pressure valve on the first calandria 6.

As a preferable technical solution, a smoke outlet is further opened on the upper wall surface of the operation box body 1.
