Abstract
The invention discloses a device for extracting lignin by water-assisted dissolution. The device comprises a cooking boiler and a settling box, wherein the cooking boiler is connected with the settling box through a guide tube; the top end of the cooking boiler is provided with a feed port, and the lower part is provided with a heating bin; a stirrer is arranged in the settling box, the top end is provided with a water inlet, and the bottom is provided with a filter screen; and a baffle is horizontally arranged above the filter screen. The cooking boiler is connected with the settling box through the guide tube in which the screen is arranged; after finishing boiling, the valve is opened, the benzene sulfonate-lignin mixed solution flows into the settling box, and the stirrer can thoroughly mix the benzene sulfonate-lignin mixed solution with water, so that the lignin completely separates out and precipitates; and the bottom of the settling box is provided with the filter screen, the baffle is drawn out after precipitating completely, the waste liquid enters the waste liquid container, the lignin stays on the filter screen, and the coarse lignin can be collected after the filter screen is dismounted. The device is simple to operate, and has obvious effects.
Description
Technical field:
The present invention relates to a kind of water-soluble hydrotropy and extract the device of lignin, belong to lignin extraction dress
Put field.
Background technology:
Lignin is the important Natural organic sources with extensive use, in agricultural, oil, smelting
Before having a wide range of applications on gold, dyestuff, cement and concrete industry and Macromolecular materials industry
Scape.Lignin is present in plant, need to it be extracted from plant during use, present
The device of lignin extraction is less, operates the most cumbersome.
Summary of the invention:
In order to solve the problem existing for background technology, present invention employs solution below:
A kind of water-soluble hydrotropy extracts the device of lignin, including digester and settling tank, described steaming
Saucepan is connected with settling tank by conduit, and the top of described digester is provided with charging aperture, and lower section sets
Having heating cabinet, be provided with agitator in described settling tank, top is provided with water inlet, and bottom was provided with
Filter screen, described drainage screen upper horizontal is provided with baffle plate.
Further, described digester side is provided with discharging opening.
Further, it is provided with backstop in described conduit.
Further, described drainage screen is detachable.
Further, it is provided with waste liquid access device below described drainage screen.
Further, described conduit is provided with valve.
Connect with conduit between digester and the settling tank of the present invention, and in conduit, be provided with backstop,
Valve is opened in steaming and decocting after completing, benzene sulfonate-lignin mixed liquor flows into settling tank, agitator
Can make benzene sulfonate-lignin mixed liquor and water be sufficiently mixed make lignin separate out completely, heavy
Forming sediment, the bottom of settling tank is provided with drainage screen, extracts baffle plate out after precipitation is complete, and waste liquid enters waste liquid
Access device, lignin is trapped on drainage screen, pulls down drainage screen and just can collect rough wooden
Element.The present invention is simple to operate, and effect is notable.
Accompanying drawing illustrates:
Fig. 1 is overall structure front view of the present invention；
Fig. 2 is overall structure top view of the present invention.
