Steam cycle environment-friendly supply system based on gasified light hydrocarbon

Abstract

The invention discloses a steam cycle environment-friendly supply system based on gasified light hydrocarbon. The system includes a light-hydrocarbon gasification system and a combustion boiler. The light-hydrocarbon gasification system includes a gas making tank, an oil storage tank, a gas intake tank, a liquid circulating heater, a neutralization tank and a gas storage tank. The oil storage tank where liquid light hydrocarbon is stored is connected with the gas making tank through a pipeline and inputs the liquid light hydrocarbon into the gas making tank. The gas intake tank is connected with the gas making tank through a pipeline and inputs pressured air which promotes light-hydrocarbon gasification into the gas making tank. The liquid circulating heater is connected with the gas making tank through a pipeline to conduct heating. In the gas making tank, by the input of the liquid light hydrocarbon mixed with the pressured air, the liquid light hydrocarbon is physically converted into high-concentration gasified light hydrocarbon under the action of high temperature, and through pipeline connection, the high-concentration gasified light hydrocarbon is output into the neutralization tank. The neutralization tank is connected to an air-mixed pressure regulating device, and because of air input into the neutralization tank by the air-mixed pressure regulating device, the constituent ratio of the gasified light hydrocarbon to the air in the mixed fuel gas is (15-21): (85-79) in the neutralization tank. The mixed fuel gas in the neutralization tank is input into the gas storage tank by the pipeline connection and stored.

Description

[0001] Technical field: [0002] The invention relates to the technical field of energy and environmental protection, in particular to a steam cycle environmental protection supply system based on gasification of light hydrocarbons. [0003] Background technique: [0004] In recent years, with the rapid development of my country's economy, energy consumption has been increasing day by day. Although my country imports a large amount of oil and natural gas every year, the pressure of energy shortage is becoming increasingly prominent. At the same time, liquid light hydrocarbons, as derivatives in the production process of oil and gas fields and refineries, are an associated by-product of pentane mixed hydrocarbons that can be seen in most oil and gas fields, natural gas fields, refineries, and petrochemical plants at home and abroad. . Due to its scattered origin, high cost of purchasing and storage, complex components and other reasons. Liquid light hydrocarbons are difficult ...

[0007] On the other hand, for cleaning linen, in the past, not only the demand for steam was large, but the combustion energy consumption rate was high, and there was also a lot of waste in the use process. If energy consumption can be reduced while , the recycling of steam can further reduce the fuel cost of linen washing enterprises and promote environmental protection
