Abstract
The utility model discloses a glycerin production tail gas safe and environmental-friendly processing device which comprises a buffer tank (1) provided with padding, a water absorption groove (2), a back-fire relief valve (3), a combustion furnace (4) and a safety valve (5). The buffer tank (1) with the padding is connected with the back-fire relief valve (3) through a pipeline and then connected with the combustion furnace (4), and a branch pipeline between the buffer tank (1) with the padding and the back-fire relief valve (3) is connected with the safety valve (5) and then is connected to the water absorption groove (2). By means of the glycerin production tail gas safe and environmental-friendly processing device, the environment can not be polluted when tail gas in glycerin production with waste animal and vegetable oil and methyl alcohol as raw materials is processed, production safety can be guaranteed, and secondary energy source recycling can be achieved.
Description
Technical field
The utility model relates to the auxiliary equipment of carrying out glycerol production take waste and old vegetable and animals oils and methyl alcohol as raw material, is specifically related to glycerol production tail gas safe environment-friendly processing unit.
Background technology
Grease in the waste and old vegetable and animals oils and methyl alcohol reaction generate biodiesel and glycerol mixture, after separation, neutralization, reclaiming most of methyl alcohol, have obtained being dissolved with the crude glycerine of a small amount of methyl alcohol, organic combustibility, penetrating odor.This crude glycerine can not in industrial application, need process industry to be refined to and meet the requirement of GB/T13206-2011 " glycerine " quality index because purity is lower, impurity is many, peculiar smell is arranged.Because the glycerine heat decomposition temperature is lower, on producing, need under high vacuum state, by distillation glycerine is separated with other impurity, and high vacuum state generally be provided by the high vacuum unit.Therefore, in the purification of glycerin production process, a small amount of methyl alcohol, organic combustibility, irritative gas are extracted out by the high vacuum unit, if directly discharging, flammable, irritative gas will affect production environment and safety; If glycerol production tail gas is directly sent to the combustion furnace internal combustion, when tail gas pressure fluctuation occurred or has a power failure suddenly, tempering may appear, cause security incident.
Summary of the invention
The purpose of this utility model provides a kind of tail gas safe environment-friendly processing unit when carrying out glycerol production take waste and old vegetable and animals oils and methyl alcohol as raw material, to realize when processing tail gas, neither polluting environment, can guarantee production safety again, can realize that also secondary energy sources reclaim again.
For realizing above purpose, the utility model glycerol production tail gas safe environment-friendly processing unit comprises surge tank, water absorption cell, spark arrester, combustion furnace and the safety valve with filler; Described surge tank with filler connects combustion furnace by pipeline behind spark arrester; Pass to the water absorption cell after drawing the lateral connection safety valve between with the surge tank of filler and spark arrester.
Said structure glycerol production tail gas safe environment-friendly processing unit has the following advantages:
(1) by surge tank the methyl alcohol in the condensation tail gas is recycled, improved added value.
(2) safety devices such as spark arrester, safety valve, pressure release absorption cell are set, prevent from owing to the tail gas pressure oscillation or have a power failure suddenly causing the tempering accident to occur.
(3) when spark arrester occurs to stop up, can pass through the safety valve pressure release, guarantee the equipment safety operation.
Description of drawings
Accompanying drawing is the utility model glycerol production tail gas safe environment-friendly processing unit structural representation.
Each parts is shown in the accompanying drawing: with surge tank 1, water absorption cell 2, spark arrester 3, combustion furnace 4 and the safety valve 5 of filler.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, the utility model glycerol production tail gas safe environment-friendly processing unit comprises surge tank 1, water absorption cell 2, spark arrester 3, combustion furnace 4 and the safety valve 5 with filler; Described surge tank 1 with filler connects combustion furnace 4 by pipeline behind spark arrester 3; Pass to water absorption cell 2 after drawing lateral connection safety valve 5 between with the surge tank 1 of filler and spark arrester 3.
Filler in the described surge tank adopts 304 stainless steels or 316 stainless steel ripple fillers.
Owing to containing a small amount of methyl alcohol, organic combustibility, irritative gas in the glycerol production tail gas, in sending to the combustion furnace combustion process, corresponding safety device need to be set, otherwise tempering easily occurs, cause security incident.Adopt the glycerol production tail gas safe environment-friendly processing unit of said structure, extract tail gas out first through containing filler surge tank 1 by the high vacuum unit, behind spark arrester 3, go again combustion furnace 4 internal combustion, between surge tank 1 and spark arrester 3, safety valve 5 is set, when tail gas pressure surpassed safety valve 5 setting pressure, the decontamination water station was processed after safety valve 5 pressure release emission gases were absorbed by water absorption cell 2.Regularly condensation Methanol Recovery in the surge tank 1 is utilized.
Claims (1)
