Abstract
The invention discloses a kind of with the method for house refuse production compound fertilizer: it is the following steps are included: carry out scalping, magnetic separation, broken, screening, ingredient, mixing, granulation for the house refuse after compost, it is characterized by: before carrying out scalping, first house refuse is transported in drying unit be evaporated, deodorization, sterilization processing.The advantages that there is the present invention corruption not pollute sufficiently, and technical maturity, manufacturing requirements is low, easy to operate, there is higher practical reference value.
Description
Technical field
The present invention relates to a kind of methods with house refuse production compound fertilizer.
Background technique
A large amount of rubbish is toppled in city or cities and towns daily, these rubbish had not only occupied a large amount of soil, but also seriously polluted people
The environment of class existence, and this phenomenon also increases with being continuously increased for population.The method of existing processing rubbish is removed
Incinerator is burned or is buried and fills out outside the lowland of mountain valley, there are also house refuse is carried out centralized classification, carries out compost after screening, magnetic separation
Fermentation, then, classification processing；Wherein corresponding element is added as needed and becomes organic fertilizer for farmland for fines
Material；But on the one hand this fines through compost, classification decomposes not exclusively, belong to and replacing in slow nutrient, and N, P, K therein ratio
Example is uneven, and C/N ratio is higher, and contained organic matter is also slow, so, it is directly that its is agricultural without processing, it is difficult to send out
Wave fertilizer efficiency.On the other hand, Natural fermentation not only needs the air storage place of large area, but also since fermentation process is in dew
It, fermentation odor smokes day, in substance forms a kind of new pollution sources.
Summary of the invention
Purpose of the present invention is to provide a kind of production with house refuse, fertilizer efficiency height, organic matter micro-element nutrition
The method for the organic composite fertilizer that composition is more, does not pollute.
It is an object of the present invention to what is be achieved, it the following steps are included: by after compost house refuse carry out scalping,
Composite heat transfer base-material is arrived in magnetic separation, broken, screening, and then the nutrient according to needed for different crops, designs and reasonably match
Side, nutrient insufficient section can be used inorganic fertilizer addition, remix, granulating.Before carrying out scalping, first house refuse is conveyed
It carries out being evaporated deodorizing sterilizing processing in drying unit.
Temperature in drying unit is controlled at 250 DEG C -380 DEG C, and is made using the rotation of the drying roller on drying unit
With the quantity with charging, residence time of the rubbish in drying roller is controlled, makes the humidity for carrying out the rubbish of magnetic separation after drying
Between 14%-18%.
In technical solution of the present invention, an infrared and ultraviolet line disinfection treatment can be also carried out again to the rubbish after screening.
The present invention compared with existing production technology there is corruption not pollute, technical maturity, manufacturing requirements sufficiently
It is low, it is easy to operate the advantages that, have higher practical reference value.
The present invention is described in detail for following example.
It preferably selects in a natural environment through spontaneous fermentation, decomposed or semi-decomposed house refuse, because such rubbish is organic
Matter content is high, and partially protein is enclosed in vivo by microorganism, and better decomposition can be played in subsequent technique.
Rubbish is transported on the roller of drying unit with belt conveyer first and be evaporated deodorizing sterilizing processing, drying unit
Operation is to send hot wind to roller with hot-blast stove, pressure fan, is controlled with the temperature guaranteed in rolling at 300 DEG C or so, and utilize
The quantity of charging and the rotary action of roller control rubbish residence time in roller, so that the rubbish humidity after drying exists
14%-18%, meanwhile, during drying, with foul smell, the exhaust gas in exhaust blower suction cylinder；Foul smell, the exhaust gas of extraction
It is discharged after deodorization chamber * winding paper, wash water tower, water treatment facilities processing, to reduce the pollution of environment.Second step scalping, is broken at magnetic separation
Broken, screening: the scalping machine that the rubbish after being evaporated deodorization is sent to 30mm sieve pore is carried out scalping by belt conveyer, will be less than 30mm
Thin block powder is sent into magnetic separation, removes iron filings, then crushed with pulverizer, is then fed again into screening machine dusting cover, obtains being less than 3mm
Following organic fertilizer base-material.The disinfection of third step infrared and ultraviolet: the house refuse after dusting cover is transported to infrared sterilizing equipment decontaminating apparatus and is carried out
Infrared and ultraviolet disinfection, to reach the bacterium killed in rubbish.4th step compound organic fertilizer production: the organic fertilizer after measurement disinfection
Expect base-material constituent content, and according to nutrient and needs needed for different crops, carries out ingredient, be then sufficiently mixed uniformly
Afterwards, it adopts and is granulated by any known method to get product of the present invention.
Claims (3)
1. a kind of with the method for house refuse production compound fertilizer: it is the following steps are included: the house refuse after compost is carried out slightly
Sieve, magnetic separation, broken, screening, ingredient, mixing, granulation, it is characterised in that: before carrying out scalping, be first transported to house refuse
It is evaporated in drying unit, deodorization, sterilization processing.
2. the method according to claim 1 with house refuse production compound fertilizer, it is characterised in that: the drying dress
Set, in temperature control at 250 DEG C -380 DEG C, and using roller rotary action and charging quantity, control rubbish drying
Residence time in equipment for drying, the rubbish humidity 14%-18% after making drying.
3. the method according to claim 1 or 2 with house refuse production compound fertilizer, it is characterised in that: the life after screening
Rubbish living carries out an infrared and ultraviolet line disinfection again.
