Problems solved by technology
External heating to prevent "ice blockage" requires the consumption of energy such as electric energy and gas, and also consumes consumables such as electric heating cables and thermal insulation materials.
[0005] As mentioned above, the traditional external heating method or dosing delivery method is mature, but it has the disadvantages of high energy consumption, poor stability, and cumbersome maintenance.

The invention discloses a double-channel gas vortex self-heating device. At least one air inlet hole is formed in the position, close to a vortex chamber, of a vortex pipe body and is connected with the vortex chamber through a pressure reducing nozzle so as to press high-pressure natural gas obtained after pressure reducing into the vortex chamber. Cold airflow formed by a vortex generator in thevortex chamber is located at the middle portion, formed hot airflow is wrapped at the outer portion of the cold airflow and extends to a hot airflow branch pipe from the vortex chamber, and the tailend of the hot airflow branch pipe is connected with a downstream pipeline. One end of the hot airflow branch pipe communicates with the hot airflow branch pipe, and the other end of the hot airflow branch pipe communicates with the vortex chamber so that hot airflow in the hot airflow branch pipe can enter the vortex chamber again along a hot airflow circulation pipe so as to form circulation airflow with the hot air in a heat end pipe. A hot airflow ring wrapped at the outer portion of the cold airflow obtained after rapid pressure reducing can be formed by the hot airflow in the vortex chamber. The double-channel gas vortex self-heating device is simple in structure, convenient to operate and high in heat energy utilization rate and has the beneficial effects that secondary energy consumption is avoided, maintenance is avoided, and the heating effect is good.
Description
technical field [0001] The invention relates to the technical field of gas transportation such as natural gas and coal gas, in particular to a dual-channel gas vortex self-heating device. Background technique [0002] Natural gas is a gaseous fluid with relatively low viscosity. After being extracted from the gas mine, it first undergoes purification processes such as dehydration, desulfurization, and dust removal, and then it is transported through high-pressure pipelines, and then the pressure is reduced to a safe range by step-by-step pressure reduction. to downstream users. The depressurization process of high-pressure natural gas at distribution stations along the line is approximately a process of adiabatic expansion. When depressurized by the pressure regulating equipment of the gas transmission station, the temperature drops sharply due to the "Joule-Thomson effect", and the water contained in the natural gas Steam and hydrates formed due to high pressure are easy t...
