Description
Technical field
This utility model is related to biogas fermentation field of engineering technology, especially relates to a kind of high temperature clad steel plate biogas fermentation
Tank.
Background technology
Biogas fermentation can produce substantial amounts of carbon dioxide, accounts for the 40% of biogas total amount, and carbon dioxide solubility becomes in water
Become the very strong carbonic acid of corrosivity, it will produce serious corrosion to the marsh-gas fermentation tank built using steel construction, particularly ferments
The air chamber position of tank.Because the biogas of firm output contains the water vapour of saturation, carbon dioxide corrodes steel by dissolving in water vapour
Structure.Biogas fermentation also can produce the hydrogen sulfide of a small amount of, and hydrogen sulfide is a kind of very strong gas of corrosivity, and it also can be to fermentation tank
The steel construction of air chamber produces corrosion.The position that marsh-gas fermentation tank is worn by corruption is all located at greatly air chamber, in order to carry out to marsh-gas fermentation tank
Interior anti-corrosion, generally using the method brushing various anticorrosive paints.But various anticorrosive paint restricted lifetime, will lose efficacy for 35 years.
Re-start preservative treatment, need to empty feed liquid in tank, manipulation strength is big, loaded down with trivial details, delay long-play, of a high price.
Using the marsh-gas fermentation tank of pure stainless steel making, because expense is too high, few use.Need a kind of use cost badly relatively low and prevent
The good marsh-gas fermentation tank of rotten effect.
Utility model content
The utility model proposes a kind of high temperature clad steel plate marsh-gas fermentation tank, low cost of manufacture, durable in use, using effect
Good.
The technical solution of the utility model is achieved in that
By corrosion resistant plate system in a kind of high temperature clad steel plate marsh-gas fermentation tank, the tank body made including ordinary steel and tank body
The tank skin becoming；Described tank body upper end is provided with fermentation tank top board, and this fermentation tank top board includes the rustless steel towards described tank body cavity
Flaggy and towards the ordinary steel flaggy outside tank body；It is provided with heat-insulation layer outside tank body.
Further, described heat-insulation layer is vacuum heat-preserving brick layer or insulating foam layer.
Further, the bottom of described tank body is provided with waste material discharge gate, dismountable on this waste material discharge gate is provided with plug.
Further, it is provided with air vent on the top of described tank body, this air vent is provided with air bleeding valve.
Further, described tank interior cavity is divided into two-layer, the fermenting cellar including lower floor and the air storage chamber on upper strata.
Further, the periphery of described tank body is provided with least 3 charging apertures of diverse location.
Further, it is provided with heat exchanger tube in described tank body.
Employ technique scheme, the beneficial effects of the utility model are:
1) tank body main body is formed around inner tank wall using ordinary steel steel plate, and fermentation tank top board is also directed towards tank interior
Side corrosion resistant plate is just set, outside be ordinary steel make, both there is extraordinary decay resistance, ruggedness is good, simultaneously
It is also greatly reduced manufacturing cost.
2) it is the heat insulation effect ensureing tank body, prevent setting heat-insulation layer outside thermal loss, this fermentation tank.Heat-insulation layer is usual
For vacuum heat-preserving brick layer or insulating foam layer, therefore, tank body has good heat-insulating property, good energy saving property, reduces biogas and sends out
Heat cost during ferment.
3) periphery of tank body is provided with least 3 charging apertures of diverse location, can select corresponding charging aperture as needed
Carry out filler, facilitate easy-to-use.
