A Natural Gas Heating and Filtration Separation System

technical field

The utility model belongs to the field of natural gas turbine pretreatment equipment, in particular to a natural gas heating and filtering separation system. the

Background technique

Before natural gas enters the turbine, it generally needs to be filtered through a filter separator to filter out solid impurities and liquid impurities in the gas. The filtering effect of natural gas becomes poor, and the ignition temperature of the gas turbine cannot be reached. the

Utility model content

In order to solve the problems of poor filtering effect and failure to reach the ignition point when the natural gas temperature is too low, the utility model designs a natural gas heating and filtering separation system. the

The technical solution of the utility model to solve the above problems is: a natural gas heating and filtering separation system, including a heater and a filter separator fixed on the base, the heater and the filter separator are connected through a main pipeline, and the air inlet of the main pipeline is fixed A thermometer, a heater and a filter separator are respectively connected in parallel with bypass pipes. Its advantages are: the utility model can effectively remove the solid particle impurities and liquid droplets in the natural gas fuel by heating the lower temperature natural gas through the heater and entering the filter separator, so as to meet the requirements of the gas turbine on the temperature and cleanliness of the gas fuel . A thermometer is fixed at the inlet end of the pipeline. When natural gas that meets the operating temperature of the turbine enters the pipeline, it enters the filter separator through the bypass pipeline, and can also enter the turbine through the bypass pipeline during maintenance. the

In the natural gas heating and filtering separation system, a differential pressure gauge is connected in parallel at both ends of the filtering separator. Its advantages are: the differential pressure gauge detects the filtering condition of natural gas, judges whether the filter separator is blocked, and prevents danger. the

In the natural gas heating and filtration separation system, the main pipeline and the filtration separator are respectively connected with safety pressure release valves. Its advantage is: when the natural gas in the pipeline reaches a certain pressure, it will be released automatically. the

In the natural gas heating and filtration separation system, the interior of the filter separator is divided into an upper chamber and a lower chamber by an orifice plate, a liquid level gauge connected to the chamber is fixed outside the filter separator, and a filter element is fixed in the upper chamber. Its advantages are: after the filter element filters the natural gas, the impurities will settle to the lower cavity due to gravity, and a small amount of liquid will accumulate in the upper cavity. Bit, regular sewage. The liquid level gauge in the lower cavity observes the liquid level to prevent the liquid level from submerging the inlet, and regularly discharges sewage. the

In the natural gas heating and filtration separation system, pressure gauges are fixed on the main pipelines at both ends of the filtration separator. Its advantages are: keep abreast of pipeline pressure and prevent pipeline blockage. the

In the natural gas heating and filtration separation system, a nitrogen replacement port and a sewage discharge port are opened at the bottom of the filter separator. Its advantages are: the role of the nitrogen replacement port is to replace the residual natural gas inside the equipment with nitrogen during equipment repair or maintenance, so as to avoid accidents such as explosions. the
