Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of biomass gas filtering device that the present invention proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is the structural representation of a kind of biomass gas filtering device that the present invention proposes.
With reference to Fig. 1, a kind of biomass gas filtering device that the present invention proposes, comprising: casing 1, screen pack 2, case lid 3;
Casing 1 inside is provided with the cavity for holding filtered fluid, the sealed groove 12 that casing 1 top is provided with opening and arranges around this opening, case lid 3 is positioned at sealed groove 12, case lid 3 is positioned at this opening part, casing 1 inside is provided with filter screen stand 11, filter screen stand 11 has groined type structure, screen pack 2 is arranged on filter screen stand 11, casing 1 sidewall is provided with air inlet, gas outlet, air inlet is positioned at below screen pack 2, gas outlet is positioned at above screen pack 2, air inlet place is provided with air inlet pipe 4, gas outlet place is provided with escape pipe 5, casing 1 sidewall is also provided with the anti-overflow lip of filtered fluid, filtered fluid recovery port, the anti-overflow lip of filtered fluid to be positioned at below screen pack 2 and to be positioned at above air inlet, the height of screen pack 2 is H1, the height of the anti-overflow lip of filtered fluid is H2, 20mm≤H1-H2≤30mm, air inlet is positioned at below the anti-overflow lip of filtered fluid, gas outlet is positioned at above the anti-overflow lip of filtered fluid, in filtered fluid recovery port, place is provided with valve 6,
The limiting bracket stretched out is provided with downwards, limiting bracket shape and box opening form fit, when case lid 3 is positioned at sealed groove 12, against screen pack 2 upper surface bottom limiting bracket bottom case lid 3.
In the biomass gas filtering device course of work of the present embodiment, first case lid is opened, filtered fluid is added in casing, screen pack is arranged on filter screen stand, case lid is placed in sealed groove, make to compress screen pack bottom the limiting bracket below case lid, carry out spacing to screen pack, then in sealed groove, liquid is added, achieve water-stop, thus improve filter box sealing property, in filter process, by air inlet pipe, the high-temperature fuel gas produced in biological fuel gasification furnace is passed in casing, high-temperature fuel gas first with filtered fluid generation chemical reaction, filtered fluid is by the tar that contains in combustion gas and pernicious gas filtering, filtered fluid also has suction-operated to the flue dust in combustion gas simultaneously, the bubble that gas is formed in filtered fluid rises to filtered fluid surface, the screen pack being positioned at filtered fluid ullage carries out secondary filter to it, in specific operation process, screen pack suitably can add asbestos, the sorptive materials such as cleaning ball promote clean-up effect further, the pure combustion gas obtained through twice filtration treatment is discharged by escape pipe, tar in filtered fluid and impurity are by filtered fluid recovery valve 5 regularly recycling, achieve the saving of resource, when filtered fluid liquid level in Rose Box is too high, unnecessary filtered fluid will eject by overflow pipe the generation preventing from filtering the problems such as hydrorrhea case, when casing internal gas pressure is too high, case lid can by the air pressure in casing intermittent upwards jack-up by a small margin, autobalance box house air pressure, case lid and casing collide simultaneously, and generation chimes of doom, plays alarm function.
