Abstract

Disclosed is a process for comprehensively recycling urban tree branches and leaves. The process is characterized in that firstly, the collected tree branches and the collected leaves are sorted, and leaf rubbish is made into animal feed; the leaf rubbish is dried at 80 DEG C-120 DEG C and then smashed, the smashed leaf rubbish and concentrated feed which is composed of corn, wheat bran and oil residues according to proportioning are evenly mixed and then subjected to granulation and drying to prepare the animal feed; and tree branch rubbish is carbonized into carbon products, the tree branches with diameters of over 3cm are directly carbonized and activated by steam to be made into wood charcoal. Deadwood branches, dead leaves and straw rubbish are made into organic fertilizers, the deadwood branches, the dead leaves, plant ashes and the tree branch rubbish which are produced during trimming of lawns and flowers are carbonized into charcoal powders produced in the process of carbonization, and animal manure is matched for mixed fermentation to obtain carbon based organic fertilizers.

Description

City branch, leaf comprehensive reutilization technique

Technical field

The present invention relates to a kind of comprehensive recycling process of rubbish, be specifically related to the recycling of city tree, branches and leaves class rubbish, belong to the technical field of chemical industry.

Background technology

For the beautifying city, street corner, city kind has expired various trees, flowers and plants, and sanitation worker people need frequent pollard, sweep leaf, especially to the autumn and winter sky, can produce a large amount of leaf and flowers and plants deadwood, these branches, leaf are entrucked and carried away after by sanitationman's cleaning usually, between burn.Burning has not only been wasted resource but also has been polluted environment.

China Patent Publication No. be CN1208723 disclosure of the Invention a kind of production method of compound organic and inorganic fertilizer, its key problem in technology is: after the organic matters such as stalk, weeds, leaf or shell of all kinds of crops are ground into powdery, under 85-100 ℃ temperature, sterilize, then mix in 20-30 ℃ enclosed environment with nitrogenous fertilizer, potash fertilizer, phosphate fertilizer, WS protease and trace element fertilizer, after mixing compound organic and inorganic fertilizer; This Chemical Mixed Fertilizer content of organic matter is high, but and the activating soil microorganism, promote effective release and the conversion of nitrogen, phosphorus in soil and the chemical fertilizer, improve chemical fertilizer utilization ratio.

Summary of the invention

The object of the invention is to, a kind of city branch, leaf comprehensive reutilization technique are provided, to improve the economic worth of city branch, leaf, to overcome the existing above-mentioned shortcoming and defect of prior art.

The technical problem that will solve required for the present invention can be achieved through the following technical solutions: a kind of city branch, leaf comprehensive reutilization technique, it is characterized in that, and first branch, the leaf rubbish collected are classified,

(1) leaf class rubbish is made animal feed

(a) with the leaf collected through 80 ℃-120 ℃ oven dry, pulverizing;

(b) proportioning is mixed by the fine fodder that corn, wheat bran, the dregs of fat form;

(c) granulate, dry;

(2) branch class garbage carbon changes into carbon product

(a) will make charcoal after the branch direct carbonization of diameter more than 3cm, the steam activation;

(b) branch of diameter below 3cm pulverized, dried, makes carry out again after the semi-finished product batten making charcoal after carbonization, steam activation, the oven dry.

(3) deadwood dead leaf, weeds class rubbish are made fertilizer

The deadwood dead leaf, plant ash, (2) the branch class garbage carbon that cut the grass on a lawn, flowers produce are changed into the charcoal powder that produces in the carbon goods process, be equipped with again animal manure and carry out mixed culture fermentation, make charcoal base fertilizer.

As preferably, the ratio of leaf is 85% in described (1), the ratio of fine fodder is 15%.

As further preferred, the ratio of corn is 5% in the mixture that is comprised of leaf and fine fodder in described (1), and the ratio of wheat bran is 5%, and the ratio of the dregs of fat is 5%.

As preferably, the leaf in described (1) is leaf of elm tree, white poplar leaf.

As preferably, the ratio of withered branch is 70% in described (3), and the ratio of plant ash is 10%, and the ratio of charcoal powder is 5%, and the ratio of animal manure is 10%.

Beneficial effect of the present invention: leaf, branch class branches and leaves rubbish are classified, leaf class rubbish is made fertilizer; Branch class rubbish is made carbon product; With withered branch, cut the grass on a lawn, prune the charcoal powder that weeds class rubbish that flowers produce and carbonisation produce and make charcoal base organic fertilizer, this mode has improved the economic worth of leaf, branch class branches and leaves rubbish greatly, has also protected environment simultaneously.

The specific embodiment

Below in conjunction with specific embodiment, the present invention is done progressive explanation.Should be understood that following examples are only for explanation the present invention but not for limiting scope of the present invention.

A kind of city branch, leaf comprehensive reutilization technique is characterized in that, first branch, the leaf rubbish collected are classified, and are divided into the leaf class, branch class, deadwood dead leaf, weeds class three classes.

(1) leaf class rubbish is made animal feed

(a) leaves such as the leaf of elm tree collected, white poplar leaf are removed moisture through 80 ℃ of-120 ℃ of oven dry, again through pulverizing;

(b) fine fodder with 85% leaf proportioning 15% mixes, and described fine fodder is comprised of corn flour, wheat bran, the dregs of fat, and the ratio of corn is 5% in the mixture that wherein is comprised of leaf and fine fodder, and the ratio of wheat bran is 5%, and the ratio of the dregs of fat is 5%;

(c) mixture that is comprised of leaf and fine fodder is delivered in the granulation machine and is granulated, and drying is namely finished the making of animal feed again; After the feed of granulation shape, not only convenient transportation but also convenient storage.

(2) branch class garbage carbon changes into carbon product

(a) branch of diameter more than 3cm directly being sent to retort carries out making the charcoal finished product after carbonization, the steam activation;

(b) branch of diameter below 3cm pulverized first, dried, deliver to and be processed into the semi-finished product batten in the machine-made charcoal machine, send the semi-finished product batten to retort and carry out carbonization, steam activation, make the charcoal finished product after the drying.

(3) deadwood dead leaf, weeds class rubbish are made fertilizer

The deadwood dead leaf 70%, plant ash 10%, (2) the branch class garbage carbon that cut the grass on a lawn, flowers produce are changed into the charcoal powder 10% that produces in the carbon goods process, after being equipped with again animal manure 10% and carrying out mixed culture fermentation, make charcoal base fertilizer.

The present invention has improved the economic worth of leaf, branch class branches and leaves rubbish greatly, has also protected environment simultaneously.

More than the specific embodiment of the present invention is illustrated, but the present invention is as limit, only otherwise break away from aim of the present invention, the present invention can also have various variations.
