Description

Technical Field

[0001] The utility model relates to the technical field of natural gas heating equipment, in particular to a natural gas heating device. Background Art

[0002] With the rapid development of national industry, natural gas has become a popular energy source in many fields. Natural gas refers to a mixture of hydrocarbons and non-hydrocarbon gases naturally stored in the strata. In petroleum geology, it usually refers to oilfield gas and gasfield gas. It mainly exists in oil fields and natural gas fields, and a small amount is also found in coal seams. The main use of natural gas is as fuel, which can be used to make carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry.

[0003] Under certain conditions, natural gas needs to be processed using a heating device. For example, after liquid natural gas is converted into gaseous natural gas, the temperature is still a little low and needs to be heated up so that it can be transported to the client for use. When heating natural gas, if the temperature is too high, natural gas is prone to explosion and safety accidents. Therefore, it is necessary to monitor the temperature in the heating device and cool it down in time when the temperature is too high. Utility Model Content

[0004] The utility model aims to design a natural gas heating device so as to achieve safe heating and prevent accidents caused by over-high temperature.

[0007] Furthermore, in the above-mentioned natural gas heating device, the heat medium inlet and the heat medium outlet are arranged so that the flow direction of the heat medium is opposite to the flow direction of the natural gas.

[0008] Furthermore, in the above-mentioned natural gas heating device, the heat exchange tube is a bent tube.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a natural gas heating device, in which natural gas can enter the device body from the natural gas inlet, and leave the device body from the natural gas outlet after passing through the heat exchange tube. When passing through the heat exchange tube, the natural gas exchanges heat with the heat medium in the heat exchange area, so that the temperature of the natural gas increases. When the temperature sensing probe detects that the temperature inside the device body is too high, cold air can be introduced into the cold air pipe through an external cold air blower to cool the device body in time. The natural gas heating device can monitor the temperature inside the device body and cool it down in time when the temperature is too high, thereby achieving safe heating and preventing accidents caused by excessive temperature.
