Abstract

The invention relates to a large-sized biogas fermentation device integrating fermentation and gas storage, comprising a feed port, a liquid outlet port and a dreg discharge port. The large-sized biogas fermentation device integrating fermentation and gas storage is characterized by comprising a casing, a gas generation chamber installed in the casing and a gas storage floating cover sleeved outside the gas generation chamber, wherein a water layer is arranged between the casing and the gas generation chamber; the gas generation chamber is internally provided with a biogas stirring device; and the bottom part of the gas storage floating cover is provided with balancing weights. The invention has the following advantages of compact structure, small occupied space, and convenient operation, management and maintenance due to the integration of fermentation and gas storage, safe and reliable use, ensuring of gas generation amount in winter, improvement of gas generation amount due to complete fermentation of raw materials and large-scale industrial production for facilitating the popularization of biogas.

Description

The large-sized biogas fermentation device that integrates fermentation, gas storage
Technical field:
The invention belongs to a kind of firedamp gas equipment, particularly a kind of large-sized biogas fermentation device that integrates fermentation, gas storage.
Background technology:
Biogas is as a kind of renewable energy source, and not only cleaning, cheap, health but also developing eco-agriculture and all many-sides such as environment protection and comprehensive utilization demonstrate its unique advantages gradually are subjected to people's great attention.But there is following defective in existing firedamp gas equipment: 1, need to connect between methane-generating pit and biogas burner biogas is carried out purifying treatment and pressure controlled equipment, as devulcanizer, tensimeter etc., the piping attachment that these equipment claimed are installed is many, occupation space big and operation, management and maintenance are all not too convenient.2, the pressure transient of biogas is in use made troubles to the user.3, gas production rate is low, generally about 100 cubes.4, fermentation vat does not have attemperator, and the factor of created gase in winter is lower.5, owing to adopt the one-piece construction of concrete placement, operating efficiency is low, can't carry out the large-scale industrialization manufacturing, thereby has seriously restricted popularizing and promoting of biogas.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of large-sized biogas fermentation device that integrates fermentation, gas storage, this device integrates fermentation, gas storage, and compact construction, gas production rate is big, biogas pressure is stable, but and large-scale industrialization production.
Technical scheme of the present invention is: a kind of large-sized biogas fermentation device that integrates fermentation, gas storage, comprise opening for feed, liquid outlet and slag notch, and it is characterized in that: by shell, aerogenesis chamber in the enclosure is installed and is enclosed within the outdoor storage air-float hood of aerogenesis and form; Between shell and the aerogenesis chamber is water layer; The indoor biogas whipping appts that is equipped with of aerogenesis, balancing weight is equipped with in storage air-float hood bottom.
Above-mentioned biogas whipping appts is made up of with the motor that is connected with main shaft main shaft, the agitating vane that is installed on the main shaft.
Above-mentioned housing exterior is provided with thermal insulation layer and heat-sink shell.
On the above-mentioned storage air-float hood means of deflation is housed.
The present invention has following advantage and positively effect:
1, owing to integrate fermentation, gas storage, so compact construction, occupation space is little and operation, management and easy to maintenance.
2, owing between shell and aerogenesis chamber, be water layer, therefore can prevent the biogas leakage that aerogenesis is indoor effectively, safe in utilization, reliable.
When 3, the biogas when enter the storage air-float hood from the aerogenesis chamber in increases gradually, pressure in the storage air-float hood increases gradually, in order to prevent that storing up air-float hood rises, and is equipped with balancing weight in the bottom of storage air-float hood, make the constant weight of storage air-float hood and balancing weight, guarantee that the biogas pressure in the storage air-float hood is stable.And the design also is equipped with means of deflation on the storage air-float hood, thereby can further guarantee the safety of the stable of biogas pressure and storage air-float hood, brings convenience for the user uses.
4, owing to be not provided with thermal insulation layer and heat-sink shell, therefore both can absorb extraneous heat in large quantities, and make fermentation more abundant, can be incubated again, thereby guarantee the gas production rate in winter in the shell outside part.
5, owing to, therefore raw material is fully fermented, improve gas production rate at the indoor whipping appts that is equipped with of aerogenesis.
6, therefore the design can carry out large-scale industrialization production owing to use steel to make, and is convenient to promoting the use of of biogas.
Description of drawings:
Fig. 1 is a front view of the present invention.
Fig. 2 is a sectional view of the present invention.
Embodiment:
As shown in the figure: a kind of large-sized biogas fermentation device that integrates fermentation, gas storage, by shell 1, aerogenesis chamber 2 in the enclosure is installed and is enclosed within the outdoor storage air-float hood 3 of aerogenesis and form.For raw material is fully fermented, improve gas production rate, aerogenesis is indoor to be equipped with by main shaft 4, be installed in the biogas whipping appts that agitating vane 5 and the motor 6 that is connected with main shaft on the main shaft are formed.For the biogas leakage that prevents that aerogenesis is indoor, between shell and aerogenesis chamber, water 7 is housed.Biogas is too much in the air-float hood, pressure is excessive in order to prevent to store up, and in storage air-float hood upper bottom portion balancing weight 8 and purging valve 9 is housed.In order to guarantee the gas production rate in winter, be provided with thermal insulation layer 10 and heat-sink shell 11 in housing exterior.The front of above-mentioned storage air-float hood is provided with opening for feed 12, the back is provided with liquid outlet 13 and slag notch 14, and tensimeter 15 and venting port 16 are equipped with in the top of storage air-float hood.
