Description

A kind of plant refuse comprehensive utilization method

Technical field

The present invention relates to a kind of is raw material with the plant refuse, realizes comprehensive utilization method by destructive distillation, and concrete is a kind of plant refuse comprehensive utilization method.

Technical background

In people's industrial and agricultural production and daily life, can produce branch, leaf, bark, wood shavings, sawdust, bamboo, rattan, straw, grass, husk, maize peel, corn cob, etc. contain the vegetable fibre waste, the tree branches that some are good-for-nothing, mulberry shoot, flaw-piece, bamboo, rattan are normally burnt as the firewood charcoal, utility value is not high, also causes environmental pollution easily.Contain the vegetable fibre waste in a large number, then become rubbish as waste of shell, pericarp and vegetables, flowers etc., these wastes ferment in rubbish and rot, grow the fly worm, serious contaminate environment.

Summary of the invention:

The objective of the invention is to propose a kind of plant refuse comprehensive utilization method, this method is a raw material with containing the vegetable fibre waste all, adopt the method for water-cooled to improve the plant vinegar liquid rate of recovery, improve the plant vinegar liquid rate of recovery by the control exhaust smoke level, reduce the content of the suspended substance in the flue gas, reduce the pollution of flue gas, and plant charcoal is carried out processing treatment, make it become the subsidiary material of soil improvement agent and fertilising, dispenser air.

Technical scheme of the present invention is: a kind of plant refuse comprehensive utilization method, it is characterized in that raw material all is the plant refuse that contains vegetable fibre, and concrete grammar is:

(1) plant refuse classification and remove impurity, Cutting Length be to less than furnace diameter,

(2) dried plant waste, controlling moisture content is less than 25%,

(3) plant refuse is put into charring furnace and burns,

(4) by adjusting exhaust air rate, temperature is 200-400 ℃ in the control stove, and charring furnace smoke temperature is 80-150 ℃, and condenser smoke temperature is 15-30 ℃,

(5) smoke exhaust pipe of charring furnace communicates with the plant vinegar liquid withdrawer, with condenser temperature is reduced to 15-30 ℃ in the plant vinegar liquid withdrawer,

(6) reclaim and handle plant vinegar liquid,

(7) reclaim tar,

(8) come out of the stove after the plant refuse carbonization in the charring furnace, cooling,

(9) reclaim and handle plant charcoal.

The concrete grammar of described recovery and processing plant vinegar liquid is: plant vinegar liquid flows into container through going out the plant vinegar liquid pipe, and plant vinegar liquid filters, and leaves standstill 4-5 and precipitates in individual month, and the coke cleaning oil of removal come-up is got the middle part clear liquor, checks, packs, puts in storage.

It is that to adopt thickness be that the powdery filtering layer of 30-50 millimeter, the particulate filter layer that thickness is the 80-100 millimeter, powdery filtering layer, the two layers of filter paper that thickness is the 30-50 millimeter successively filter that described plant vinegar liquid filters, described powdery filtering layer is that 80-100 purpose sawdust or powdered carbon are formed, and described particulate filter layer is a particle diameter greater than 4 millimeters activated carbon granule.

The method of described recovery and processing plant charcoal is: the plant charcoal cooling; plant charcoal is crushed to the 80-100 order; add the plant nutrition composition, add water, transfer PH=5-7; mixing and making material is bulk; nodulizer is granulated, and with the temperature oven dry that is lower than 80 ℃, control moisture content is less than 2%; check, pack, put in storage, become the subsidiary material of soil improvement agent and fertilising, dispenser.

The plant nutrition composition of described adding is calcium, phosphorus, boron, magnesium, manganese, zinc.

The described plant refuse that contains vegetable fibre is branch, leaf, bark, wood shavings, sawdust, bamboo, rattan, straw, grass, husk, maize peel, corn cob, shell, pericarp, bagasse and the rubbish that contains vegetable fibre.

Described charring furnace is mechanical charring furnace or brick charring furnace.

Raw material of the present invention is branch, flaw-piece, bamboo, rattan, plant refuses such as the mulberry shoot of cutting off every year as mulberry tree, dried-up bamboo, rattan can also be leaf, bark, wood shavings, sawdust, straw, grass, husk, maize peel, corn cob, shell, pericarp, bagasse even the rubbish that contains vegetable fibre.So not only made full use of resource, also the rubbish that contains vegetable fibre can have been turned waste into wealth, for new approach has been opened up in refuse treatment.

The present invention is because whole raw material comes from waste or rubbish, removal of impurities, classification to raw material are very important, non-plant material such as the metal in the raw material, plastics, rubber need be removed, the raw material of same stove should be selected same class raw material, can guarantee the plant vinegar liquid quality like this.Main points of the present invention are to adopt the method for water-cooled and control exhaust smoke level to control condensing temperature, to improve the plant vinegar liquid rate of recovery, particularly reduce the content of the suspended substance in the flue gas, reduce the pollution of flue gas to air, after tested, fume emission of the present invention has reached relevant emission standard.By the adjustment exhaust air rate, temperature in the may command stove, exhaust air rate is big, and temperature is then high in the stove, and exhaust air rate is little, and temperature is then low in the stove, 60-80 ℃ of common smoke temperature control, secondary smoke temperature is 30-50 ℃.The present invention also adjusts temperature in the condenser by the flow of adjusting water coolant, makes the temperature of flue gas in condenser be controlled at 30-50 ℃, and is good at this temperature range interplantation vinegar output of fluid high quality.Plant vinegar liquid is through bed filtration, and leaving standstill becomes the plant vinegar liquid that serves many purposes with removing impurity and tar light oil.The resulting plant charcoal of the present invention is a low-firing, through pulverizing, add the required nutrition of plant, granulates, and then becomes the subsidiary material of soil improvement agent fertilising, dispenser.The required nutrition of plant is to prepare according to the different demands of each kind of plant, also will adjust according to the soil property and the water quality of various places.The product that the present invention obtains also has tar.The present invention is applicable to fairly large mechanical charring furnace, the brick charring furnace that the scale that also is applicable to is less.The present invention is to the plant refuse comprehensive utilization, has improved the value of these plant refuses greatly.The present invention has adopted science and simple method to improve the plant vinegar liquid rate of recovery, reduce the content of the suspended substance in the flue gas, reduce the pollution of flue gas, and plant charcoal is carried out processing treatment, make it become the subsidiary material of soil improvement agent and fertilising, dispenser air.The inventive method is scientific and reasonable, range of product is many, quality is good, output is high, can not cause environmental pollution.
