Abstract
The invention relates to a double-coil-tube type electric-heating natural gas gasification heat exchanger, which comprises an exchanger body, a gas-state natural gas coil, a gas-state natural gas inlet valve, a liquid-state natural gas coil, a liquid-state natural gas inlet valve and an electric heater; the exchanger body is a closed container filled with heat transfer medium water; the gas-state natural gas coil, the liquid-state natural gas coil and the electric heater are arranged in the exchanger body and immersed in the heat transfer medium water; the gas-state natural gas coil and the liquid-state natural gas coil are respectively connected with pipelines outside the exchanger body; and the gas-state natural gas inlet valve and liquid-state natural gas inlet valve are respectively arranged on a gas-state natural gas inlet pipeline and a liquid-state natural gas inlet pipeline. The invention has the advantages that: the natural gas gasification heat exchanger has a simple structure, low cost and a small size, saves energy sources, is safety and reliability in running and suitable for a large-size fuel gas company, a city gate station, an industrial park station building and a residential cell station building.
Description
(1) technical field
The present invention relates to rock gas station gasification application apparatus, particularly a kind of double plate tubular type electric heating natural gas gasifying heat exchanger.
(2) background technique
Usually be respectively equipped with electric heating liquified natural gas (LNG) vaporizer and gaseous natural gas (BOG) heat exchanger on the natural gas gasifying sled, a gasification sled is gone up and is placed the area that two electric heating heat transmission equipments have not only increased the gasification sled, also increased simultaneously the floor space of station, and adopt two electric heaters, not only power consumption is big, and has increased operation cost.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, a kind of double plate tubular type electric heating natural gas gasifying heat exchanger is provided, this apparatus structure is simple, cost is low, energy saving, safe and reliable to operation, walk altogether under the situation of an electric heating gasification heat exchanger at BOG gas and LNG liquid, can reduce the floor space of gasification sled and reduce electric energy.
Technological scheme of the present invention:
A kind of double plate tubular type electric heating natural gas gasifying heat exchanger, comprise body, the gaseous natural gas coil pipe, the gaseous natural gas inlet valve, the liquid natural gas coil pipe, liquified natural gas inlet valve and electric heater, body is the seal container that heat transferring medium water is housed, the gaseous natural gas coil pipe, liquid natural gas coil pipe and electric heater all are arranged in the body and are immersed in the heat transferring medium water, the gaseous natural gas coil pipe is connected with the body Outer Tube respectively with the liquid natural gas coil pipe, and gaseous natural gas inlet valve and liquified natural gas inlet valve are located at respectively on gaseous natural gas and the liquified natural gas inlet pipeline.
Working procedure of the present invention:
Opening electric heater at first, when heat transferring medium water heats and remains on 60 degrees centigrade, open gaseous natural gas inlet valve and liquified natural gas inlet valve, gaseous natural gas and liquified natural gas are respectively by gaseous natural gas coil pipe and the heat exchange of liquid natural gas coil pipe, make its air outlet temperature reach ambient temperature, be transported to downstream line separately then.
Advantage of the present invention is: this natural gas gasifying heat exchanger structure is simple, cost is low, energy saving, safe and reliable to operation, floor space is little, is applicable to large-scale gas company, urban gate station, industrial park station and residential quarter station.
