Abstract
A monomer ultra-large volume steel post cone high-temperature anaerobic fermentation system comprises: a column cone shaped tank (1), stirrers (2),(3) in the column cone shaped tank (1), four water inlets a, sludge outlets c equispaced on the tank bottom, an umbrella shaped baffle (4) in a distance below a firedamp outlet at the roof of the column cone shaped tank (1). The water distribution at the bottom of the tank is uniform and the full-tank homogeneration effect is good and the water inlet, sludge lines are centralized and conveniently managed and the land use is saved; the earth water is prevented from being on the gas outlet to benefit for performing the post-order firedamp purification treatment; and each tank stress in the tank set does not interfered each other and the safety of the whole of the tank set is ensured; when the high-temperature anaerobic fermentation system is in regular service, the COD average removal rate is stably above 80% and the coarse firedamp yield of each device can be 30000m3; suitable for large-scale tank group construction and the engine total investment is saved up by 10-30%.
Description
Technical field
The present invention relates to the energy-saving and emission-reduction technical field of waste water processing, specifically the monomer ultra-large volume steel post cone high-temperature anaerobic fermentation system.
Background technology
The eighties in last century, Nanyang alcohol head factory (existing day hat group) is with bioenergy whipping appts (number of patent application: 85104232) be applied to conventional post taper anaerobic reactor, built two 5000m
3The high-temperature anaerobic fermentation jar, daily output biogas 30000m
3Civilian for the Nanyang, produced good economic benefit.According to the statistic data reckoning of actual motion for many years, the water inlet COD volumetric loading of this high-temperature anaerobic fermentation jar is 5.14～8.34kgCOD/ (m
3D), mean value is 6.76kgCOD/ (m
3D); The COD clearance is 76.9%～90%, and mean value is 83.7%.
Utilize the bioenergy whipping appts to mix fully, the organic pollutant in the water into fully contacted and the removal of being degraded with microorganism, have simple in structure, not additionaling power, stable, stir the successive characteristics.
Facts have proved that the effect that the post taper anaerobic reactor that uses bioenergy to mix device is handled the alcohol industry high concentrated organic wastewater is good.
But, former 5000m
3Still there are the following problems in actual motion for the high-temperature anaerobic fermentation jar:
1. monomer pond appearance is bigger, and single water entry water inlet is adopted at a jar end, although the water distribution of branch cotton umbrella is arranged, it is uneven that water distribution is still disliked.The monomer pond holds big more, and this problem is obvious more, will influence full pond and stir homogenizing effect.
2. jar end shore pipe and water inlet pipe layout are disperseed, and when jar group quantity increases, will be unfavorable for the pipeline centralized management.
3. when the anaerobic jar biogas output is big, there is muddy water to carry under one's arms often to enter the situation of tank deck biogas pipe to take place, be unfavorable for the purifying treatment of postorder biogas.
4. the total canal of anaerobic jar water outlet water sealed tank and water outlet is rigid the connection with tank body, lacks flexible transition, if jar group quantity increases, stressed influencing each other between each jar will produce potential safety hazard to the jar cohort.
Summary of the invention
It is even to the objective of the invention is to study a kind of jar of base fabric water, and water inlet, spoil disposal pipeline are concentrated, and avoids the air outlet muddy water of carrying under one's arms, and each jar is stressed in jar group does not disturb mutually, guarantees jar monomer ultra-large volume steel post cone high-temperature anaerobic fermentation system of group general safety.
Monomer ultra-large volume steel post cone high-temperature anaerobic fermentation of the present invention system, comprise: post taper tank body 1, whipping appts 2,3 is housed in the post taper tank body 1, also has jar uniform four the water-in a in the end, a mud discharging mouth c, a distance is provided with umbrella baffle plate 4 under the post taper tank body 1 top methane outlet.
The water inlet pipe 5 that links to each other with water-in a, mud discharging mouth c, shore pipe 6 layout that superposes up and down.
Independently water seal water outlet canister 7 of two in south, north is equipped with on 1 jar of outer top of post taper tank body, is connected with flexible flange 8 with post taper tank body 1.
The gap of giving vent to anger of umbrella baffle plate 4 and methane outlet is 100～300mm.
This high-temperature anaerobic fermentation new installation is a post tapered steel structure, in establish day the independent research such as still trivial grade of department of hat group and obtain the bioenergy whipping appts of national inventing patent excellent prize, leavening temperature is controlled at about 55 ℃ ± 3 ℃, the monomer useful volume is 10000m
3The process design parameter that adopts is as follows:
Volumetric loading 6.0kgCOD/ (m
3D)
Mixed liquid concentration 8～10g/L
When the COD average removal rate normally moves, can stablize and reach more than 85%
Biogas output 20～25m
3Biogas/m
3Sewage (water inlet COD concentration is 47000mg/L)
Produce biogas index 0.51m
3Biogas/KgCOD
The biogas CH that produces
4Content is about 55～60%
CO
2Content is about 38～40%
H
2S content is 700～800mg/m
3
Aerogenesis pressure malleation 0.6～0.8mH
2O
The advantage of monomer ultra-large volume steel post cone high-temperature anaerobic fermentation of the present invention system is: jar base fabric water is even, and complete jar homogenizing effect is good; The water inlet of jar group, spoil disposal pipeline are concentrated, convenient management, and land used is saved; The phenomenon of avoiding the air outlet to carry under one's arms muddy water is beneficial to the postorder marsh gas purifying and handles; Each jar is stressed in the jar group does not disturb mutually, and a jar group general safety is guaranteed; This high-temperature anaerobic fermentation new installation is when normal operation, and the COD average removal rate can be stablized and reaches more than 85%, and the individual equipment biogas output can reach 30000m
3Be applicable to the construction of extensive jar of cohort, save total investment of engineering 10%～30%.
