Description

Energy-saving pulse anaerobic reactor

Technical field

The utility model relates to a kind of sewage disposal device, especially relates to a kind of energy-saving pulse anaerobic reactor.

Background technology

At present in sewage treatment industry, contain the higher sewage of organic substrate concentration for processing, what generally adopt is the way that upflow type anaerobic reactor (being called for short UASB) is handled, the deficiency of the main existence of this equipment is: one, this equipment water distributor power are mainly from a water pump, if treatment sewage concentration of suspended matter height, the power of a water pump does not reach requirement far away, cause anaerobic pond inside fully to carry out anaerobic reaction, the organism processing rate is very low, only about 30-40%; Its two, if because of water distributor water distribution in the anaerobic pond is not enough or uneven, general two kinds of schemes that adopt are: increase the building height of anaerobic pond, promote the internal-response rate; Another kind of scheme is to increase by one to three water pump, and with the power of enhancing water distributor, but the weak point of above two kinds of schemes is respectively: improve the anaerobic pond building height and equal enterprise to the increasing that environmental protection drops into, increased cost; Increase water pump and equal to expend the more electric power and the water resources of usefulness.Therefore, the upflow type anaerobic reactor of each enterprise's use is subjected to many unfavorable factors at present.

The utility model content

The utility model provides a kind of energy-saving pulse anaerobic reactor at the deficiencies in the prior art.

For realizing the above object, the technical solution adopted in the utility model is:

Energy-saving pulse anaerobic reactor is made of jointly anaerobic pond, water distributor, triphase separator, biogas chamber, lift pump, surge generator, producer pipe connecting, water inlet pipe, inlet pipe, escape pipe, effluent weir; Wherein, surge generator is installed in the top of anaerobic pond, be respectively equipped with water inlet pipe, inlet pipe and escape pipe in the upper end of surge generator, water inlet pipe directly links to each other with lift pump, and the biogas chamber in inlet pipe and the anaerobic pond is connected, and escape pipe passes straight through in the anaerobic pond upper space, a producer pipe connecting is installed in the surge generator bottom, directly be communicated to the water distributor of anaerobic pond bottom, effluent weir is located at the top of anaerobic pond, and triphase separator is mounted in it top according to the height of anaerobic reactor.During works better, lift pump is evacuated to water in the pulse type reactor, when water level reach a certain height, and can overflow pipe connecting inlet of water, begin to flow into the water distributor of anaerobic pond bottom, at this moment, in surge generator, form a negative pressure, produce siphonage, water in surge generator flows into water distributor in a large number, to increase the upwards thrust of water distributor inside, the sedimentary suspended sludge layer of anaerobic pond is stirred equably, in anaerobic pond, organism is carried out effecting reaction; Simultaneously, sewage, dirt and biogas separate by triphase separator, and unnecessary part water flows out from effluent weir.The biogas that forms in anaerobic pond is then delivered to the biogas chamber, when surge generator produces negative pressure because of work, the indoor biogas of biogas enters surge generator by inlet pipe, prevent that effectively the air admission anaerobic pond from destroying inner oxygen-free environment, guaranteed the interior removal of anaerobic pond organic matter of sewage 80-90%.

Wherein: 1, anaerobic pond; 2, water distributor; 3, triphase separator; 4, biogas chamber; 5, lift pump; 6, surge generator; 7, producer pipe connecting; 8, water inlet pipe; 9, inlet pipe; 10, escape pipe; 11, effluent weir;

Embodiment:

As shown in Figure 1, energy-saving pulse anaerobic reactor is made of jointly anaerobic pond 1, water distributor 2, triphase separator 3, biogas chamber 4, lift pump 5, surge generator 6, producer pipe connecting 7, water inlet pipe 8, inlet pipe 9, escape pipe 10, effluent weir 11; Wherein, surge generator 6 is installed in the top of anaerobic pond 1, and the size specification of surge generator 6 can be decided according to the volume size of below anaerobic pond 1.Be respectively equipped with water inlet pipe 8, inlet pipe 9 and escape pipe 10 in the upper end of surge generator 6, water inlet pipe 8 directly links to each other with lift pump 5, biogas chamber 4 in inlet pipe 9 and the anaerobic pond 1 is connected, escape pipe 10 passes straight through in anaerobic pond 1 upper space, in surge generator 6 bottoms a producer pipe connecting 7 is installed, directly is communicated to the water distributor 2 of anaerobic pond 1 bottom.Effluent weir 11 is located at the top of anaerobic pond 1, and triphase separator 3 is mounted in it top according to the height of anaerobic pond 1.During works better, lift pump 5 is evacuated to water in the surge generator 6, when water level reach a certain height, water producer pipe connecting 7 inlet that can overflow, begin to flow into the water distributor 2 of anaerobic pond 1 bottom, at this moment, in surge generator 6, formed a negative pressure, produce siphonage, the water in the surge generator 6 flows into water distributor 2 at short notice in a large number, to increase the upwards thrust of water distributor 2 inside, anaerobic pond 1 sedimentary suspended sludge layer is stirred equably, in the time of in anaerobic pond 1 organism is carried out effecting reaction, like this since, just need not increase anaerobic pond 2 building heights and increase the quantity of lift pump 5.Simultaneously, sewage, dirt and levitation gas are separated by triphase separator 3, and suspended sludge is continued to stay in the anaerobic pond 1, and unnecessary part water flows out from effluent weir 11, and partly gas formation biogas is then collected by biogas chamber 4.When surge generator 6 produces negative pressure because of work, biogas in the biogas chamber 4 enters in the surge generator 6 by inlet pipe 9, effectively prevent air admission anaerobic pond 1,, guaranteed anaerobic pond 1 interior effective removal organic matter of sewage in order to avoid destroy inner oxygen-free environment.

The utility model has reduced the building cost and the running cost of sewage disposal device effectively, has improved the clearance to organic matter of sewage simultaneously, is applicable to chemical industry, high-enriched organics discharge of wastewater enterprises such as pesticide producing factory.
