Abstract

The utility model relates to a marsh gas generator using the method of fermentation. The utility model comprises a fermentation chamber, wherein, the inner of the fermentation door is spaced into a plurality of small chambers by a baffle plate, and namely the baffle plate (11) which spaces the fermentation chamber into the small chambers is arranged between a side wall (12) and a spacing wall (14). A gap is reserved between the upper edge of the baffle plate (11) and a gas arch (2), and a gap is reserved between the lower edge of the baffle plate (11) and a chamber bottom (16). Thus, material liquid is mixed evenly and is fermented fully, the output of marsh gas is large, and the discharge of discharge liquid can reach indexes prescribed by departments of environmental protection. The utility model is suitable for manufacturing marsh gas in industry.

Description

Marsh gas generator

The utility model belongs to the fermentation unit technical field, is applicable to produce biogas.

At present, industrially produce the fermentation unit that biogas uses and have two kinds, a kind of is an arch form advection fermentation unit, this device in use because the deposition of old feed liquid, new and old feed liquid easily forms laminar flow and viscous flow phenomenon, can not thorough mixing; Also having a kind of device is a jar shape upflowing biogas generation tank, by stirrer feed liquid is mixed preferably in the use, but facility investment and power consumption is big.The common drawback of above-mentioned two kinds of devices is that the feed liquid fermentation is incomplete, and gas production rate is little, and discharging of waste liquid does not reach environmental administration's set quota, causes environmental pollution.

The purpose of this utility model provides a kind of biogas generating device that can make feed liquid thorough mixing, fermentation finished thoroughly1 during the fermentation.

The utility model comprise by at the bottom of the chamber of the end wall at side walls and two ends and bottom and the gas at top arch crowd around the proving room that forms, the gas arch is provided with venting hole, be provided with the longitudinal division identical with this proving room length in the middle part of proving room, the bottom of this next door one end is provided with and is communicated with the hole, on an end wall relative, feed-pipe, inoculated tube, discharge nozzle and chamber door are installed with being communicated with the hole, it is characterized in that being equipped with between sidewall and next door with proving room every the plate washer that is divided into cell, the last lower rim of plate washer leaves the gap respectively and between at the bottom of the gas arch, chamber.

The utility model has been divided into several cells by plate washer with proving room, and feed liquid is uniformly mixed carry out micro-circulating movement under the effect of plate washer in each cell, has solved laminar flow and viscous flow problem.Feed liquid is able to abundant fermentation after the circulation of some cells, thereby can make the waste liquid of discharging reach environmental administration's set quota, has reduced the environmental pollution degree.In addition, because the utility model fermentation finished thoroughly1, gas production rate is big, compares with the capacity fermentation unit with existing, and a day charging capacity can double, and gas production rate can improve 2～2.5 times, and the baffle arrangement that is adopted is simple, and cost is low, and is easy for installation.

Accompanying drawing shows embodiment of the present utility model, wherein

Fig. 1 is the front view of embodiment;

Fig. 2 is the vertical view after embodiment removes the gas arch;

Fig. 3 is the A-A sectional view of Fig. 1;

Fig. 4 is the B-B sectional view of Fig. 1;

Fig. 5 is the structural representation of embodiment middle frame.

Among the embodiment, proving room by the chamber of the end wall (9) at side walls (12) and two ends and bottom at the bottom of the gas arch (2) at (16) and top crowd around and form, the following position of gas arch (2) is cuboid, and gas arch (2) is provided with venting hole (1), in order to collect biogas.Be provided with the longitudinal division (14) identical with this proving room length in the middle part of proving room, this next door (14) are separated into two identical locellus of size with proving room.Next door (14) is provided with in the bottom of one end and is communicated with hole (13), so that two locellus are communicated with.Proving room is provided with feed-pipe (4), inoculated tube (5), discharge nozzle (15) and chamber door (7) on the end wall (9) of an end relative with being communicated with hole (13), be respectively applied for and carry feed liquid, carry bacterial classification, effluent discharge and personnel to come in and go out.The outside of feed end end wall (9) is provided with equipment pond (6), is used for installing required equipment.Between sidewall (12) and next door (14), be equipped with proving room every ten baffle plates (11) that are divided into 12 cells by framework (17), 0.2～0.4 meter of the high out-feed liquid of the upper limb of this baffle plate (11), the distance of (16) is 1/3 of a feed liquid height at the bottom of its lower rim and the chamber, and the distance between adjacent two dividing plates (11) equates with distance between sidewall (12) and next door (14).Framework (17) is separately fixed on sidewall (12) and next door (14) by the fixed feet (8) which is provided with.Lower end at the baffle plate of locating near feed-pipe (4) (11) has a base plate (10), so that feed liquid that enters and bacterial classification are mixed fully.Described proving room is optional to be formed by connecting with cement prefab, and baffle plate (11) and base plate (10) can select for use plank to manufacture.

The utility model in use, feed liquid that is used for fermenting and bacterial classification are introduced into first locellus of proving room respectively through feed-pipe (4) and inoculated tube (5), after stopping of baffle plate (11) and base plate (10) is able to thorough mixing, slowly flow forward in bottom along this locellus, ferment simultaneously, produce biogas, biogas emits the laggard air inlet chamber of out-feed liquid (3), discharges by venting hole (1).Feed liquid is proceeded fermentation by being communicated with another locellus that hole (13) enters proving room.Because baffle plate (11) has been divided into several cells with proving room, has formed multistage circulating fermentation structure, feed liquid is all carried out micro-circulating movement in each cell, thereby makes the feed liquid fermentation fully, fully, and the feed liquid of fermenting is at last discharged through discharge nozzle (15).The utility model can use two or more proving room serial or parallel connections waste residue, waste liquid that the feed liquid of use can select for use brewery, sugar refinery, starch factory, pharmaceutical factory to discharge.
