Abstract
The utility model discloses a sludge treatment system. The sludge treatment system comprises a hydrothermal treatment unit, a heat exchange desanding unit, an anaerobic digestion unit and an steam generating unit which are connected in sequence, wherein the heat exchange desanding unit comprises a heat exchanger, a desanding device and a cooling tower which are connected in sequence; the heat exchanger is connected with the hydrothermal treatment unit; the cooling tower is connected with the anaerobic digestion unit and is used for directly evaporating the sludge and lowering the temperature to reach cooling; the moisture is sped up to be evaporated under the effect of spraying and air drafting of the cooling tower, thus a lot of heat can be taken away, and as a result, the more appropriate reaction temperature can be realized while the sludge is fed into an anaerobic digestion cylinder after being processed by separating organic matters, water and inorganic matters through the desanding device, the benefit is provided for the output of the methane, the methane output potential of the sludge is greatly developed, and the cooling water is saved; and simultaneously, the heat exchange area of the heat exchanger and the cost of investment on equipment are saved, the cost of cooling the sludge is reduced, and less consumption is brought.
Description
Technical field
The utility model belongs to biomass sludge and administers the field, is specifically related to a kind of biomass sludge treatment system.
Background technology
The applicant once developed a kind of biomass sludge treatment system, comprise the hydrothermal treatment consists unit, heat exchange desanding unit, anaerobic digestion unit and the steam generating unit that connect successively, wherein, heat exchange desanding unit mainly is comprised of the heat exchanger and the sand separator that connect successively, and the inorganic silt in the mud after effectively will processing in the hydrothermal treatment consists unit is thus separated from the mixed solution that is comprised of water and organic matter.In this treatment system, inorganic silt part after sand separator is processed is discharged from its bottom, mixed solution organic and that water forms directly enters into the anaerobic digestion unit, after the anaerobic digestion reaction, excess sludge mixes with mud after the hydrothermal treatment consists cell processing through heat exchanger and carries out heat exchange, therefore, in the heat exchange link, must ensure enough water coolants just can make above-mentioned organic matter and water reach the optimum temps of anaerobic digestion unit, its floor space is larger, the equipment construction cost of investment is higher, and resource utilization is also lower.
The utility model content
For above-mentioned deficiency, the utility model provides a kind of heat exchanging apparatus investment of saving, and reduces the sludge treating system of cooling-water consumption.
The utility model is to realize by such technical scheme: a kind of sludge treating system, comprise the hydrothermal treatment consists unit, heat exchange desanding unit, anaerobic digestion unit and the steam generating unit that connect successively, described heat exchange desanding unit comprises heat exchanger, sand separator and the cooling tower that connects successively, wherein, heat exchanger is connected with the hydrothermal treatment consists unit, and cooling tower is connected with the anaerobic digestion unit.
Further, described hydrothermal treatment consists unit comprises mix and blend tank, hydrothermal reactor and the flash tank that connects successively, and described heat exchanger is connected with this flash tank.
Described anaerobic digestion unit comprises the mesophilic anaerobic digestion tank, described cooling tower is arranged between sand separator and the mesophilic anaerobic digestion tank, described mesophilic anaerobic digestion tank partly is connected by the pre-treatment of described heat exchanger with the hydrothermal treatment consists unit, namely, through the mud after the hydrothermal treatment consists cell processing during through over-heat-exchanger, carrying out after the heat exchange self temperature with excess sludge behind the anaerobic reaction reduces, enter into sand separator and carry out organic matter, water separates with inanimate matter, enter into again cooling tower, part heat transferred water coolant, this part heat has been taken away in the evaporation of water coolant, thereby can reach comparatively suitable temperature of reaction when mud enters into the mesophilic anaerobic digestion tank again.
Described mesophilic anaerobic digestion unit is connected with mix and blend tank in the hydrothermal treatment consists unit by heat exchanger, and the biogas that the mesophilic anaerobic digestion tank produces passes into steam generating unit, provides steam for hydrothermal reactor thus.
Each equipment in the described hydrothermal treatment consists unit is that many serial or parallel connection formulas connect, and, when each equipment respectively is one, is series-mode frame that is; When a certain equipment is many, be parallel structure between this equipment, thereby increase the treatment capacity in the hydrothermal treatment consists unit of cells time, enhance productivity.
Described hydrothermal reactor is closed reactor, and its internal pressure is not less than the saturated vapor pressure of mud, therefore the moisture evaporation can not occur and loses heat.
The sludge treating system that the utility model provides is set up cooling tower in heat exchange desanding unit, the cooling tower of namely between sand separator and anaerobic digestor, connecting, this cooling tower directly carries out the evaporative cooling cooling to mud, spray by cooling tower and exhausting etc., added the evaporation of moisture whole, taken away amount of heat, thereby can make through sand separator and carry out organic matter, water and mud after inanimate matter separates can reach comparatively suitable temperature of reaction when entering anaerobic digestor, the quantum of output that is conducive to biogas is developed the biogas output potential of mud greatly; Experiment shows, the temperature of reaction of mesophilic anaerobic digestion unit is generally 35 ℃～37 ℃, and the mud temperature after the hydrothermal treatment consists is generally more than 90 ℃, heat exchanger can be reduced to it 60 ℃～70 ℃ usually, after walking heat through the moisture evaporator strip of cooling tower, the temperature of mud can be reduced to 35 ℃～40 ℃, the amount of moisture of vaporization losses be equivalent to enter cooling tower sludge quantity 4%～6%, thereby greatly saved water coolant, heat interchanging area and the equipment investment cost of also having saved heat exchanger simultaneously, mud cooling expense is low, consumes few.
