Description

Oxygenating device and fermentation equipment thereof

Technical Field

The utility model relates to an environmental protection equipment technique especially relates to oxygenating devices that seal fermentation and fermentation treatment and fermentation equipment thereof.

Background

In the sludge fermentation technology with 80% of water content in the current market, generally adopts tank type compost fermentation, strip-stack type compost fermentation or common fermentation tank.

The tank type compost fermentation is that sludge, auxiliary materials (mushroom dregs, sawdust, straws, household garbage and the like) and a reverse mixed material are mixed according to fixed proportion and then are transported to an overground or underground tank of a fermentation workshop by a dumper or a forklift for aerobic fermentation, and a turner or a turner is used for regular turning in the fermentation process.

The strip-stack type compost fermentation is characterized in that sludge, auxiliary materials (mushroom slag, sawdust, straws, household garbage and the like) and a reverse mixed material are mixed according to fixed proportion and then are conveyed to a fermentation workshop or an open field by a dump truck or a forklift to be stacked and fermented in a strip form, an oxygen supply system is not used for supplying oxygen by periodically overturning and pushing, the fermentation tank fermentation is characterized in that the sludge, microbial inoculum, mushroom slag, straws, peanut shells, sawdust and the reverse mixed material are mixed according to fixed proportion and then are conveyed to a lifting hopper by the forklift, and the sludge is conveyed into a tank top feeding port by the lifting hopper and then falls into a tank body to be fermented in an aerobic mode.

Because the sludge which needs to be fermented like with different sludge component characteristics and organic matter heights needs to be added with the reverse mixing materials, mushroom residues, sawdust, straws, household garbage and the like, sludge fermentation treatment centers in the market receive sludge with the water content of 80 percent, sludge treatment centers adopt groove type composting and strip stack type composting processes, and a plurality of turners and pushers need to be arranged.

As for the requirement of -class water content of the sludge fermentation process, the water content needs to be controlled between 55% and 65%, and in addition, because the sludge with the water content of 80% is pasty and has extremely low air permeability, a large amount of auxiliary materials or back-mixed materials need to be mixed with the sludge to be fermented, because the sludge organic matters and the water content in various places are different, the proportion of some auxiliary materials or back-mixed materials to the 80% sludge is 1: 1, 1: 1.5 and 1: 2, and the proportion of part of the auxiliary materials or the back-mixed materials to the 80% sludge is 1: 3, so that the water content, the carbon nitrogen ratio and the organic.

The method comprises the steps of fermenting sludge with the water content of 80% to obtain the water content of 30%, 35% and 40%, fermenting sludge with the water content of 80% of 1 ton to the water content of 40% according to an energy conservation law, removing water with the water content of 80% of 1 ton to the water content of 40% according to a constant solid amount of 1 to (1-80) ═ 0.2/(1-40%) -0.33, and removing water with the water content of 1 to 0.67 ton according to the energy conservation law, so that the energy of partial sludge is insufficient, an ideal effect cannot be achieved in an expected fermentation period, and auxiliary materials need to be added, so that a reverse mixing material actually mainly has the effect of mixing with the sludge with the water content of 80%, the water content required by fermentation is reduced, in addition, , partial microbial bacteria are returned for utilization and culture, the material height of tank compost fermentation and strip-pile compost fermentation is limited, the reason that the material height of the tank compost fermentation and the strip-pile compost fermentation cannot be too thick at the bottom aeration material layer, the fermentation is influenced by the bottom aeration material layer, is basically 0.6-0.8 meter, 100 ton sludge with the water content of 80% per day is fermented on a small scale, the sludge, the area is calculated, the area of the auxiliary materials and the.

And the space for fermenting the trough type compost and the bar stack type compost is too large, the complete deodorization reaches the standard, the emission cost is high, the separation spectrum is mostly discharged to the atmosphere naturally, partial projects are only set even if matched deodorization is carried out, and the air quantity required by fermenting tons of sludge per hour is about 110m³The air is partially absorbed by aerobic microorganisms, most of the air is used for carrying away moisture, and the turnover is not completely uniform, so that partial finished materials are in massive and granular shapes and the like due to the fact that the non-decomposed fermented materials are not completely uniform.

The fermentation tank principle and technology are from Germany and then sold to Japan, and are introduced from Japan in 2013 by part of domestic manufacturers, the fermentation tank is used for fermenting livestock manure and kitchen waste in Japan, the fermentation tank is imitated by to to be used for sludge fermentation by a part of manufacturers, series problems occur in the sludge fermentation process, such as the fracture of a main shaft of a stirring mechanism, the fracture of blades, the fracture of ratchet teeth of a driving mechanism, the fracture of a main shaft bond, the incapability of normal discharging and the unstable yield, the frequent lifting of a culture bacterial bed always cause the sludge fermentation tank to be incapable of normal operation, a large amount of auxiliary materials are used in each place to reduce the resistance of the driving mechanism and increase the air permeability of sludge, but the fermentation yield is reduced by more than 70% compared with the livestock manure and the kitchen waste and is unstable, because the principle, design parameters and mechanical design of the fermentation tank are according to the substances of the livestock manure and the kitchen waste, and the specific gravity, the porosity, the air permeability, the components, the oxygen demand and the municipal sludge of the livestock manure.

Therefore, there is a need to research kinds of targeted sludge high-temperature aerobic fermentation equipment to solve the problems of low sludge fermentation treatment efficiency, high failure rate, large floor area, serious environmental pollution, high cost and the like in the prior art.
