Abstract

The invention discloses a vortex heater, and relates to the technical field of natural gas pipeline networks. The vortex heater comprises a heater body. A gas inlet cavity, a heating cavity and a heatexchange cavity are formed in the heater body. The gas inlet cavity communicates with the heating cavity. Gas inlets are formed in the gas inlet cavity and provided with nozzles. The nozzles inject gas entering from the gas inlets into the gas inlet cavity in the tangential direction of the inner wall of the gas inlet cavity. The heat exchange cavity is formed between an outer shell of the heaterbody and the heating cavity. A heat exchange gas inlet and a heat exchange gas outlet are formed in the outer shell of the heater body. Heat exchange pieces are arranged on the outer wall of the heating cavity. According to the vortex heater, heat generated by high-pressure gas of an inlet of a gas pipeline network is utilized for heating; mounting is simple; energy consumption is small; an outerheating source is not needed; and the heater is simple in manufacturing and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of natural gas pipeline network, in particular to a vortex heater. Background technique [0002] In the gas pressure regulating skid, because the pressure difference between the front and rear of the gas is too large or the ambient temperature is too low, the gas temperature will be too low, and the gas contains moisture, which will cause ice blockage in the gas pipeline and affect the gas supply, so a heater is required. Increase gas temperature. The heaters on the market include: electric heaters, water bath heaters, etc., all of which require an external heating source. The principle of this type of heater is: after the medium to be heated enters the heater, it flows in the annular space with the electric heating source for a certain period of time. Then flow out to achieve the purpose of raising the temperature. [0003] On June 18, 2014, the State Intellectual Property Office disclosed a utility model...
