Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, the utility model is expanded on further.In the following detailed description, Only by way of explanation, describe some one exemplary embodiment of the present utility model.Undoubtedly, this area Those of ordinary skill will be consequently realised that, in the case of without departing from spirit and scope of the present utility model, can By with various different in the way of described embodiment is modified.Therefore, accompanying drawing and being described in substantially It is illustrative, rather than be used for limiting scope of the claims.

As depicted in figs. 1 and 2, IC anaerobic reactor gas-liquid separation device, is used for being arranged on IC anaerobism The top of reactor, including separate tank body 1, the top of described separation tank body 1 is provided with gas vent 2, institute That states gas vent 2 is connected above blow-down pipe 3, and the bottom of described separation tank body 1 is connected with return duct 5, All sides of described separation tank body 1 are provided with riser, and described gas vent 2 is provided with liquid blocking mechanism.Described Riser includes the one-level riser 6 that the lower periphery side of described separation tank body 1 connects, described separation tank body 1 Last week, side was provided with two-stage hoisting pipe 7, and described one-level riser 6 and two-stage hoisting pipe 7 are anti-with IC anaerobism respectively The lower reative cell of device and upper reative cell is answered to connect.The lower reative cell of IC anaerobic reactor and upper reative cell are produced Biogas is collected by gas collector, and IC anaerobic reactor to those skilled in the art, is that known technology is at this Repeat no more, enter in described separation tank body 1 by described one-level riser 6 and two-stage hoisting pipe 7 respectively, Carrying out gas-liquid separation in described separation tank body 1, biogas enters described one-level riser 6 and two-stage hoisting pipe After 7, zymotic fluid density in described one-level riser 6 and two-stage hoisting pipe 7 declines, and with described IC Density contrast is created between the zymotic fluid that in anaerobic reactor, density is higher.The existence of this density contrast, makes to send out Ferment liquid is constantly promoted in described separation tank body 1.After isolating biogas in described separation tank body 1 Zymotic fluid is returned to the lower reative cell of described IC anaerobic reactor again by described return duct 5, thus is formed Circulation in zymotic fluid continuous print.In described separation tank body 1, isolated biogas is through the resistance of described liquid During retaining device, air velocity slows down, and in biogas, liquid falls under gravity, enters described return duct 5 Returning to the lower reative cell of described IC anaerobic reactor, biogas passes through described liquid blocking mechanism by described gas Body outlet 2 discharge.The present embodiment efficiently separates the moisture in biogas, has preferably gas liquid separating function, Biogas is made to be purified further.

Described liquid blocking mechanism includes being arranged on the gear liquid of described gas vent 2 and gives vent to anger frame 8, described gear liquid Give vent to anger and be provided with the water fender 10 of cone setting below frame 8, the perimembranous of described water fender 10 and described gas It is provided with gear liquid gas outlet 9 between outlet 2.When biogas exports, first pass through described water fender 10, because Described water fender 10 is arranged for cone, so the attachment of moisture in biogas is in the bottom of water fender 10, separately Also can flow in described separation tank body 1 along the conical surface outward, biogas is discharged from described gear liquid gas outlet 9, Under the effect of the described water fender 10 that cone is arranged, moisture non-separating in biogas separates again, makes Biogas is purified further.

Described one-level riser the 6th, described two-stage hoisting pipe 7 separates the tangentially connected setting of tank body 1 with described, When in the biogas entrance described separation tank body 1 beneficially containing moisture for the said structure, separate described in tangential impact Zymotic fluid in tank body 1, makes zymotic fluid swirling motion, plays good centrifugal action, advantageously in Gas-liquid separation.

The sidewall of described gas vent 2 is connected with out biogas pipe 4, and said structure also can collect biogas.

Described one-level riser the 6th, described two-stage hoisting pipe 7 is uniformly arranged along the circumference of described separation tank body 1, It is more beneficial for the gas-liquid separation in described separation tank body 1.

Of the present utility model general principle, principal character and of the present utility model excellent have more than been shown and described Point.Skilled person will appreciate that of the industry, the utility model is not restricted to the described embodiments, above-mentioned reality Execute and principle of the present utility model is simply described, without departing from the utility model spirit described in example and specification On the premise of with scope, the utility model also has various changes and modifications, and these changes and improvements both fall within In the range of claimed the utility model.The utility model claims scope by appending claims And equivalent defines.
