Abstract
The invention relates to a feeder for medium and large-scale biogas projects, which realizes the blockage-free feeding. The feeder comprises a feed tank, a biogas storage tank and two air compressors, the two tanks are connected with each other through a biogas outlet pipe, the feed tank is provided with two pressure gauges, a thermometer, a liquid flow meter, a feeding and discharging pipe, a biogas outlet, a plurality of ball valves, an access hole and a plurality of heat coils clinging to the inner wall of the feed tank tightly, and the biogas storage tank consists of a biogas outlet and a level. When the first air compressor operates, negative pressure is generated in the pipe to suck liquid feed into the feeder, the materials are preheated in the pipe, and the thermometer indicates the temperature in the tank; and when the second air compressor operates, positive pressure is generated in the biogas storage tank, and the liquid feed is forced to flow into an anaerobic digester under the pressure. The feed tank has the function of pre-acidification, and the liquid feed can flow back under the control of the valve according to working needs. A liquid flow meter is arranged on the liquid outlet pipe so that the flow of the feed can be adjusted according to practical working needs.
Description
Technical field
The present invention relates to be used in a kind of big-and-middle-sized biogas engineering the equipment of charging.Specifically, be a kind of no obstruction, maintenance free that is used for big-and-middle-sized biogas engineering, can preheat, pre-acidified feeder.
Background technology
Biogas engineering is in service, generally sends feed liquid to anaeroic digestor at regular time and quantity by spiral pump.Because swine manure wastewater solid content height uses the pump delivery material easily to result in blockage, and influences biogas engineering and normally moves; Spiral pump need be made regular check on, keep in repair, and causes the waste of manpower and material resources.
Summary of the invention
The invention provides a kind of feeder that is specifically designed to big-and-middle-sized biogas engineering, can preheat, can have pre-acidified effect by temperature in the thermometer index pot, can carry out feed liquid according to need of work and reflux, and the size that can regulate feed rate according to need of work.
The technical solution adopted in the present invention is: be made of a charging stock tank and a gas holder and two compressed air units, two tank bodies link to each other by tracheae.Charging stock tank is provided with two tensimeters, thermometer, liquid meter, feed and exhaust tube, air inlet port, several valves, an inspection window and is close to some circle hot coils of charging stock tank inwall.Gas holder is made up of a production well and a liquid level tube.During compressed air unit 1# operation, form negative pressure in the tracheae, feed liquid is sucked feeder, material preheats at this, observes the material heating state by thermometer; During compressed air unit 2# operation, in gas holder, form malleation, feed liquid is squeezed in the anaeroic digestor by air pressure.Charging stock tank has pre-acidified effect, by the control of valve, can carry out feed liquid according to need of work and reflux.Have liquid meter on the feed and exhaust tube, can regulate feed rate according to the real work needs.
Characteristics of the present invention are: whole process realizes charging and discharging by air pressure, is fit to the high waste water of solid content, and material does not need particular filter, and material variety is applied widely, has successfully solved the blockage problem that exists in the biogas fill process.Have hot coil in jar, can in jar, preheat, have pre-acidified effect, can carry out feed liquid according to need of work and reflux, can be by temperature in the thermometer index pot.Be provided with liquid meter, can regulate the size of feed rate according to the reality of work needs, it is big to be suitable for working range.
Description of drawings
Below with reference to embodiment and accompanying drawing the present invention is further described.
Fig. 1 is the feeder process flow sheet, and Fig. 2 is the feeder plot plan, and Fig. 3 is the charging stock tank drawing in side sectional elevation.1. feed inlet and outlets among the figure; 2. liquid meter 3. hot coils; 4. charging stock tank; 5. hot-water line support; 6. tensimeter (+); 7. tank body support; 8. tensimeter (-); 9. thermometer; 10. pore; 11. inspection window; 12. tracheae; 13. liquid level tube; 14. gas holder; 15. venting hole; 16 compressed air units.
Embodiment
In Fig. 1, during compressed air unit 1# (16) operation, form negative pressure in the gas holder, to size mixing, feed liquid sucks charging stock tank in the pond, and material preheats at this, during compressed air unit 2# (16) operation, in gas holder, form malleation, by air pressure feed liquid is squeezed in the anaeroic digestor, realized that whole process is unobstructed, do not have and stop up.Feeder has pre-acidified effect, can carry out feed liquid according to need of work and reflux.Have liquid meter on the drain pipe, can regulate feed rate according to the real work needs.Have inspection window on the charging stock tank, regularly carry out cleaning waste slag.
