Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide one and can fixed gas be recycled, thus avoiding the lightness-removing column fixed gas recycling system of the wasting of resources and the method for recycling thereof。
The lightness-removing column fixed gas recycling system of the present invention, including lightness-removing column fixed gas gas outlet, fuel surge tank, spent acid incinerator air inlet, torch altar lamp which burns day and night air inlet, described lightness-removing column fixed gas gas outlet passes sequentially through adjustment valve and the first valve connects with the air inlet of fuel surge tank, described spent acid incinerator air inlet connects with the gas outlet of torch altar lamp which burns day and night air inlet with fuel surge tank, it also includes torch gas house steward's air inlet, described torch gas house steward's air inlet is connected with the air inlet of fuel surge tank by pressure-control valve, described fuel surge tank is connected to for controlling the pressure transducer that pressure-control valve opens and closes；By the setting of pressure-control valve, when the air pressure in fuel surge tank is too high, pressure transducer can open pressure-control valve, so that fixed gas can discharge to torch gas house steward's air inlet, and then it can be avoided that because of in fuel surge tank air pressure excessive and the phenomenon that fuel surge tank explodes occurs, described torch altar lamp which burns day and night air inlet is communicated with supplementary gas tank by direct-operated regulator；Setting by supplementary gas tank and direct-operated regulator, when air pressure deficiency in torch altar lamp which burns day and night, direct-operated regulator is opened, the compression air supplemented in gas tank can add in torch altar lamp which burns day and night, it is thus possible to avoid torch altar lamp which burns day and night that the phenomenon extinguished occurs, it also includes torch gas air inlet, and described torch gas air inlet is by the pipeline communication between the second valve and adjustment valve and the first valve；Setting by torch gas air inlet and the second valve, when the air pressure in fuel surge tank is too high, can manually open the second valve, fixed gas is discharged in torch gas burner, it is possible to avoid because in fuel surge tank, air pressure is excessive and the phenomenon that fuel surge tank explodes occur。
The method that the lightness-removing column fixed gas of the present invention is recycled, comprises the following steps:
(1) fixed gas that first lightness-removing column is produced by fuel surge tank is collected, and then the fixed gas collected is cushioned；
(2) fixed gas collected is transported in spent acid incinerator and torch altar lamp which burns day and night by fuel surge tank, and the burning for spent acid incinerator and torch altar lamp which burns day and night uses；
(3) when the pressure of the fixed gas pressure overpressure sensor settings in fuel surge tank, pressure transducer controls pressure-control valve and opens, and the fixed gas in fuel surge tank is by pressure-control valve discharge to torch gas house steward's air inlet；
(4) when the pressure that the fixed gas pressure in fuel surge tank sets lower than pressure transducer, pressure transducer controls pressure-control valve and closes。
(5) when the air pressure that the pressure of torch altar lamp which burns day and night air inlet needs lower than torch altar lamp which burns day and night burning, direct-operated regulator is opened, the compression air supplemented in gas tank adds in torch altar lamp which burns day and night air inlet, it is achieved to supplementing of the pressure of torch altar lamp which burns day and night air inlet；
(6) when the pressure of torch altar lamp which burns day and night air inlet reaches the air pressure that torch altar lamp which burns day and night burning needs, direct-operated regulator is closed, and supplements the gas tank stopping pressure to torch altar lamp which burns day and night and supplements。
(7) when the pressure at fuel surge tank air inlet place exceedes the rated pressure of fuel surge tank, manually opened second valve the fixed gas that lightness-removing column produces can be directly discharged to torch gas air inlet；
(8) when the pressure at fuel surge tank air inlet place is lower than the rated pressure of fuel surge tank, can manual-lock the second valve, stop the discharge of fixed gas that lightness-removing column is produced。
The method have the benefit that the fixed gas produced in sulfuric acid alkylation production process can be recycled by the present invention, after fixed gas being directly discharged to torch gas house steward with tradition, the mode being consumed fixed gas by torch burning is compared, avoid the waste of resource, improve the economic benefit of enterprise。
