Description
Technical field
This utility model relates to tail gas disposal technique field, particularly relates to a kind of lab scale device for absorbing tail gas.
Background technology
In the past, for convenience of operation, the processing mode of some tail gas (such as cis-butenedioic anhydride gas) for producing in the lab scale evaluation test of catalyst was directly discharged in air exactly.There is very big drawback in this way, the especially discharge of some toxic and harmfuls, one pollutes the environment, furthermore test operation personnel bring the infringement on body and mind.Increasingly pay attention to along with the security protection of environmental conservation and workman is worked, although the discharge capacity of lab scale reaction end gas is little, it is also desirable to install device for absorbing tail gas additional after its device.
Cis-butenedioic anhydride gas in tail gas, by installing device for absorbing tail gas after small testing device additional, is carried out cooling and absorbing, to reduce the discharge of harmful gas by this utility model, reach the purpose of environmental protection, the cis-butenedioic anhydride simultaneously produced in all right recovery test, is fabricated to fumaric acid, is conducive to making full use of of material.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made brief description.
nullSuch as Fig. 1、Shown in Fig. 2，A kind of lab scale device for absorbing tail gas，It is characterized in that: include absorption bottle 1、Tail gas air inlet pipe 2、Drain pipe 3、Drain valve 4、Water inlet pipe 5、Water intaking valve 6、Fluid jetting head 7、Tail gas discharging pipe 8、Dividing plate 9，Described tail gas air inlet pipe 2 is positioned at absorption bottle 1 side，Described tail gas air inlet pipe 2 is connected with lab scale assay device by flexible pipe，Described drain pipe 3 is positioned at absorption bottle 1 one side bottom，Described drain pipe 3 is provided with drain valve 4，Described water inlet pipe 5 is positioned at absorption bottle 1 top near bottle mouth position，Described water inlet pipe 5 is provided with water intaking valve 6，It is internal that described fluid jetting head 7 is positioned at absorption bottle 1，Described fluid jetting head 7 is connected with water inlet pipe 5，Described tail gas discharging pipe 2 is connected with absorption bottle 1 bottleneck，It is internal that described dividing plate 9 is positioned at absorption bottle 1，Described dividing plate 9 is positioned at below fluid jetting head 7，Material used by described absorption bottle 1 is glass，Described tail gas air inlet pipe 2 is at a certain angle with liquid level，It is angle that described tail gas air inlet pipe 2 is positioned at one end mouth of pipe within absorption bottle 1，Described dividing plate 9 has several circular holes.
Working method: lab scale assay device is connected with tail gas air inlet pipe 2 by flexible pipe, cis-butenedioic anhydride gas enters in absorption bottle 1 by tail gas air inlet pipe 2, major part cis-butenedioic anhydride gas is soluble in water, small portion of gas rises to absorption bottle 1 top, running into absorption bottle 1 sidewall and dividing plate 9 condenses, only minimal amount is not only absorbed by the water and discharges from tail gas discharging pipe 2 with the gas not condensing sum.When sour water concentration reaches 30% in absorption bottle 1, get final product opening water discharge valve 4, sour water is discharged by drain pipe 3.Sour water supplements fresh water by water inlet pipe 5 after getting rid of, and fresh water enters in absorption bottle 1 via fluid jetting head 7.Also the cis-butenedioic anhydride condensing in dividing plate 9 and absorption bottle 1 sidewall can be rinsed out simultaneously.By at a certain angle to oblique for tail gas air inlet pipe 2 lower section and liquid level, so that cis-butenedioic anhydride gas contacts with water with maximum area, increase the assimilation effect of water, it is angle that tail gas air inlet pipe 2 is positioned at one end mouth of pipe within absorption bottle 1, it is more beneficial for gas and enters absorption bottle 1, absorption bottle 1 installs additional dividing plate 9 and is conducive to the condensation of cis-butenedioic anhydride gas.Absorption bottle 1 adopts glass to manufacture, it may be clearly seen that absorbs the sour water color that cis-butenedioic anhydride is later, observes the reaction effect of evaluation test more intuitively, not only solves environmental issue, can also have part fumaric acid output simultaneously, be conducive to making full use of of material.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
