Intelligent and highly efficient heating system of exposed points of natural gas pressure regulating station

Abstract

The invention discloses an intelligent and highly efficient heating system of exposed points of a natural gas pressure regulating station. The system comprises at least two heating heat sources, a natural gas transmission pipeline, a temperature adjusting air circulation pump, a temperature adjusting air circulation pipeline, an air booster pump, an air eddy current pipe and a control circuit. The heating heat sources are divided into at least two work groups. Two ends of each heating heat source in the corresponding work group communicate with the natural gas transmission pipeline through current collection pipes. The temperature adjusting air circulation pipeline communicates with each heating heat source through the temperature adjusting air circulation pump. The air inlet end of the air eddy current pipe communicates with the air booster pump, and the high temperature air inlet end and the low-temperature air outlet end communicate with each heating heat source through a current guide branch pipe. The air inlet end of the air booster pump communicates with the temperature adjusting air circulation pipeline. The system is simple in structure, highly universal and expandable, and high in heat exchange efficiency and comprehensive recycling rate of rest heat; the change and adjustment flexibility of devices are high; and stability and reliability of operation of heating devices are high.

Description

technical field [0001] The invention relates to an intelligent and efficient natural gas pressure regulating station dew point heating system, which belongs to the technical field of natural gas pressure regulating stations. Background technique [0002] At present, in the application process of natural gas, it is often necessary to adjust the temperature of natural gas to meet the needs of transportation and use. At present, when adjusting the temperature of natural gas, it is mainly based on the traditional heat exchanger as the main structure, and then The natural gas is heated by heat exchangers using external heat sources such as water baths and oil baths. Although it can meet the needs of natural gas heating operations, the efficiency of heating operations is relatively low, and the natural gas is heated and adjusted during the heating process. The capacity is relatively poor, and the utilization rate of waste heat is relatively low, which leads to the relatively low w...

[0002] At present, in the application process of natural gas, it is often necessary to adjust the temperature of natural gas to meet the needs of transportation and use. At present, when adjusting the temperature of natural gas, it is mainly based on the traditional heat exchanger as the main structure, and then The natural gas is heated by heat exchangers using external heat sources such as water baths and oil baths. Although it can meet the needs of natural gas heating operations, the efficiency of heating operations is relatively low, and the natural gas is heated and adjusted during the heating process. The capacity is relatively poor, and the utilization rate of waste heat is relatively low, which leads to the relatively low working efficiency of natural gas heating and relatively high operating energy consumption and cost. To solve this problem, it is urgent to develop a new natural gas Heating system to meet the needs of actual use
