Heat exchanger for natural gas pressure adjusting station

Abstract

The invention provides a heat exchanger for a natural gas pressure regulating station, which includes a heating pipe, a condenser, a temperature sensor, a pressure sensor, an anti-leakage pipeline, a natural gas collection box, an alarm, a gas transmission pipe and a solenoid valve, and the right end of the temperature sensor is arranged with a Condenser, a heating pipe is installed at the right end of the condenser. This design enables the temperature control device to heat or cool the natural gas pipeline according to the actual temperature of the natural gas pipeline. The pressure sensor is placed inside the anti-leakage pipeline, and a solenoid valve is fixed at the lower end of the anti-leakage pipeline. , the lower end of the electromagnetic valve is welded with a gas transmission pipe, the right end of the gas transmission pipe is installed with a natural gas collection box, and the upper end of the natural gas collection box is equipped with an alarm. This design can collect leaked natural gas and prevent natural gas from leaking into the air. The invention has high heat transfer efficiency , good stability, high reliability, and high security.

Description

technical field [0001] The invention relates to a heat exchanger for a natural gas pressure regulating station, which belongs to the field of heat exchanger equipment. Background technique [0002] In the existing technology, the natural gas pressure regulating station is an important part of the gas turbine combined cycle power plant. It is the main processing system of natural gas and directly affects the reliability and economy of the gas turbine combined cycle unit. When the upstream gas supply terminal provides When the pressure of natural gas is different from the pressure required by the gas turbine, it is necessary to adjust the pressure of the natural gas. Considering that the temperature of the natural gas will be affected after the pressure adjustment, in order to avoid the temperature change of the natural gas pipeline from damaging the gas turbine, the temperature of the natural gas at the inlet of the gas turbine should meet certain requirements. Therefore, the...

Problems solved by technology

[0003] The existing heat exchangers used in natural gas pressure regulating stations cannot regulate the natural gas pipelines by themselves according to the changes of the natural gas pipelines. When the pressure is higher than that of the heat exchanger device, the natural gas will leak and an explosion will occur in case of an open flame, which will bring huge safety hazards to the power plant
