A device for noise reduction, ice blockage prevention and cold energy utilization of natural gas pipelines

Abstract

The invention relates to a device for denoising, ice blockage prevention and cold energy utilization of a natural gas pipeline. The device relates to the technical field of pipeline systems, and is characterized in that two sections of natural gas pipelines (4) are connected into a whole through a pressure regulating valve (2); a heat exchange flat pipe (1) with an outer coating (3) is wrapped on the whole natural gas pipeline (4) and the pressure regulating valve (2); a solar heater (8), a summer indoor cold supply system for working and living areas (9) and a natural gas heating furnace (10) are connected in parallel between a water segregator (7) and a water collector (11); the water collector (11) is provided with a pipeline connected to one end of the heat exchange flat pipe (1); the other end of the heat exchange flat pipe (1) is connected with a circulating pump (6) through the pipeline and then connected to the water segregator (7); and a constant pressure tank (5) is connected to an inlet of the circulating pump (6). The device can control aerodynamic noise of the pressure regulating valve of the natural gas pipeline to be within a state-specified standard, is large in noise reduction, alleviates the problem of ice blockage, is obvious in cold energy utilization effect, does not affect flow rate, is simple and convenient to install, and is low in cost.

Description

technical field [0001] The invention is a device for noise reduction, ice blockage prevention and cold energy utilization of natural gas pipelines. It relates to the technical field of piping systems. Background technique [0002] The pressure regulating valve in the natural gas pipeline station is the main source of noise. The noise generated after the ordinary pressure regulating valve without noise reduction design can reach more than 100dB(A) through field measurement. Due to the high water content of the natural gas to be transported and the cooling of the ambient temperature, the pressure regulating valve will be blocked by ice, which will affect the transportation. The temperature of the transported natural gas decreases after being depressurized by the pressure regulating valve. If the cold energy produced can be utilized, additional economic benefits will be generated. [0003] At present, there is an electric heating anti-icing injection pipe technology, which is...
