Abstract
The invention relates to a process for preparing biofuel from biological waste. The process comprises the following steps: squeezing water out of biological waste firstly, then classifying the biological waste into two classes and treating the two classes of biological waste at the same time, wherein the first class of sewage is used for producing biogas, heat generated through biogas combustion is used for drying, and the second class of biological waste blocks is cut,; conveying the cut biological waste into drying equipment for drying; processing the waste gas discharged from the drying equipment by primary cleaning equipment and secondary cleaning equipment and discharging when the standard is reached; pelleting dried biological waste into finished products in pelleting equipment. The process provided by the invention overcomes the defects of the processing process in the prior art that harmful gas pollutes the environment, power generation cost is high in the case of fuel addition, equipment investment is high, and the rate of return is low; and through the specific process design, the process for preparing biofuel is free from environment pollution, does not need additional heat consumption, and is low in production cost.
Description
Technical field
The present invention relates to a kind of technology of utilizing biologic garbage to make biofuel.
Background technology
Human in development; Standard of living is improving constantly, and various biologic garbages are also day by day increasing, and the processing to various biologic garbages at present comprises garbage loading embeading, burning etc.; Wherein science is with the direct combustion power generation of rubbish, and this above-mentioned the whole bag of tricks all can bring secondary pollution.From the method for the direct combustion power generation of biologic garbage is analyzed, be with the biologic garbage burning, produce heat and generate electricity.Its technical process is that biologic garbage is concentrated fermentation, mixes into a spot of coal or the oil generation heat that burns together again.The defective of this technical matters is: 1. biologic garbage is moist, and calorific value is low, and rate of combustion is low, and obnoxious flavour that combustion processes produces and fermenting process produce foul smell can bring pollution to environment.2. because calorific value is low, it is high to add the cost that generates electricity behind the fuel.3. having high input of equipment, return rate is low.
Summary of the invention
In order to overcome existing existing the problems referred to above of biologic garbage treatment technology; The present invention provides a kind of technology of utilizing biologic garbage to make biofuel, and this utilizes biologic garbage to make the free from environmental pollution and heat exhaustion that need not add of process of biofuel technology.
The present invention solves its technical problem institute adopting process flow process and comprises:
At first biologic garbage is carried out water squeezing processing, the biologic garbage after the water squeezing is divided into two types also to be handled simultaneously,
The sewage of the first kind gets into the sewage centralized pool; Sewage in the sewage centralized pool is admitted to the biogas retort; The biogas that produces in the biogas retort is through the roasting kiln burning, and its heat energy is sent into drying plant, and the residue that produces in the biogas retort gets into the settling tank deposition; The residue of post precipitation is sent into drying plant after press filtration, the clear water of post precipitation gets into the secondary-cleaned pond; Secondary-cleaned equipment is sent in clear water one tunnel circulation in the secondary-cleaned pond, and another road replenishes sends into the primary purification pond; Primary purification equipment is sent in purification water one tunnel circulation in the primary purification pond, sends the biogas retort back to after the waste concentration of purification water raises,
Second type block biologic garbage shreds processing; Biologic garbage after the chopping delivers into the drying plant oven dry; The waste gas that drying plant is discharged passes through qualified discharge behind primary purification equipment, the secondary-cleaned equipment successively, and it is finished product that the biologic garbage after the oven dry delivers into the granulating equipment granulation.
The chopping treatment process comprises crosscut and the perpendicular two procedures of cutting.
External warming-up device of biogas retort and gas transmission equipment.
Gas transmission equipment inserts in the bottom of biogas retort.
The present invention is through the design of above-mentioned idiographic flow, has the advantage of the free from environmental pollution and heat exhaustion that need not add of the process of making biofuel.
Description of drawings
Below in conjunction with accompanying drawing and embodiment detailed content of the present invention is described.
Accompanying drawing is a process flow sheet of the present invention.
Embodiment
As shown in the figure, the concrete technical process of the present invention comprises:
At first biologic garbage is carried out water squeezing processing, dehydration reaches about 35%, and water squeezing processing can be adopted drum extrusion or dull and stereotyped pressure filtering technique, and the biologic garbage after the water squeezing is divided into two types also to be handled simultaneously.The sewage of the first kind gets into the sewage centralized pool; Sewage in the sewage centralized pool is admitted to the biogas retort; External warming-up device of biogas retort and gas transmission equipment, gas transmission equipment inserts in the bottom of biogas retort, and its effect is that stirred tank is utilized remaining biogas, and can kill the bacterium in the retort, and warming-up device can make the reaction in the retort quicken.The biogas that produces in the biogas retort is through the roasting kiln burning, and its heat energy is sent into drying plant, and the residue that produces in the biogas retort gets into the settling tank deposition; The residue of post precipitation is sent into drying plant after press filtration, the clear water of post precipitation gets into the secondary-cleaned pond; Secondary-cleaned equipment is sent in clear water one tunnel circulation in the secondary-cleaned pond, and another road replenishes sends into the primary purification pond; Primary purification equipment is sent in purification water one tunnel circulation in the primary purification pond, sends the biogas retort back to after the waste concentration of purification water raises.Second type block biologic garbage shreds processing; The chopping treatment process comprises crosscut and the perpendicular two procedures of cutting, and the biologic garbage after the chopping delivers into the drying plant oven dry, drying course dehydration about 25%; The waste gas that drying plant is discharged passes through qualified discharge behind primary purification equipment, the secondary-cleaned equipment successively, and it is finished product that the biologic garbage after the oven dry delivers into the granulating equipment granulation.
Biologic garbage becomes the TA of biofuel:
Biologic garbage becomes the calorific value of biofuel about 4000 kilocalories, can supply various boiler combustions, is almost to replace coal and oily equivalent fuel.The biofuel commercial value is about 650 yuan/ton; Technology of the present invention can be handled the biologic garbage about 500 tons every day; Can be made into 150 tons of left and right sides biofuels; Manufacturing biofuel expense per ton is about 250 yuan, and biofuel profit per ton can reach about 60,000 yuan of profits every day about 400 yuan.
The energy and environmental benefit:
Extract 150 tons of biofuels every day, be equivalent to 85 tons national standard coal.Because production process is pollution-free, be equivalent to can reduce about 56100 tons of CO2 emissions in, reduce about 280 tons of sulphur dioxide emission.
Above-described embodiment describes a kind of preferred implementation of utilizing biologic garbage to make the technology of biofuel of the present invention; Be not that the design and the scope of inventing limited; Under the prerequisite that does not break away from the present invention program; Various external form modification and improvement that those skilled in the art make technical scheme of the present invention all should fall into a kind of protection domain that utilizes biologic garbage to make the technology of biofuel of the present invention.
