Description
Technical field
The present invention relates to overheat steam technology fields, comprehensive more particularly, to a kind of superheated steam anaerobic carbonization organic matter to be
System and method.
Background technique
It is generated in many Intermediates Industry production processes such as medicine intermediate, pesticide intermediate, printing and dyeing intermediate, food big
With high salt, the high-COD waste water of amount, the improvement discharge of such waste water are always the world-famous puzzle of wastewater from chemical industry industry.It is steamed by multiple-effect
The solid slag salt formed is dried in hair, embrane method filtering, spray, and waste liquid is formally only transformed into solid waste form, having substantially
There is no eliminate for the harmful organic matter of poison.It, can will be in slag salt currently, superheated steam anaerobic carbonization technology disclosed in the relevant technologies
Organic carbon cracking, to make dangerous waste slag salt become available industry byproduct or common solid waste, so that counter push away solution
The emission problem of high COD, industrial wastewater with high salt.But organic matter superheated steam is met in carbide furnace will high temperature cabonization
Cracking, but the prerequisite of high temperature cabonization cracking is " anaerobic ", certainly, this " anaerobic " condition refers to anoxic or oxygen deprivation, phase
To anaerobic, not absolute anaerobic.How superheated steam anaerobic carbonization cracking technology existing for prerequisite is guaranteed, it is ensured that overheat is steamed
Vapour can carbonization organic matter be effectively current technical problems to be solved.Meanwhile after superheated steam anaerobic carbonization cracking organic matter
A large amount of organic exhaust gas can be generated, organic matter includes the various organic matters in high salt, also including in electronic waste, greasy filth, sludge
Organic matter, component is sufficiently complex, if superheated steam is in carbonization treatment without the complete exhaust treatment system of a set of science
Organic matter while protecting environment, can generate new pollutant simultaneously and destroy atmospheric environment.
The information disclosed in the background technology section is intended only to deepen understanding of the general background technology to the present invention, and
It is not construed as recognizing or implying in any form that the information constitutes the prior art known to those skilled in the art.
Summary of the invention
The purpose of the present invention is to provide a kind of superheated steam anaerobic carbonization organic matter integrated system and methods, existing to solve
There is technical problem present in technology.
To achieve the goals above, the invention adopts the following technical scheme:
In a first aspect, the present invention provides a kind of superheated steam anaerobic carbonization organic matter integrated system, which is characterized in that packet
It includes: feeding system, carbide furnace, discharge system, overhead steam boiler and exhaust treatment system；The feeding system passes through air exclusion
The connection of the feed inlet of mechanism and carbide furnace；The discharge system is connected by the discharge port of air exclusion mechanism and carbide furnace；Institute
Overhead steam boiler is stated to connect with carbide furnace；The exhaust treatment system is connect with carbide furnace, passes through air-introduced machine pump drainage carbide furnace
Exhaust gas, the exhaust treatment system can heat the overhead steam boiler using the temperature of exhaust gas.
As a kind of further technical solution, the exhaust treatment system includes: the cyclone separator set gradually, rotation
Wind deduster, deodorization stove, waste heat boiler, air heat exchanger, half-dried chilling tower, Dry absorption device, bag filter, air inducing
Machine, spray column, absorption tower and chimney；The air inlet of the cyclone separator is to be processed in carbide furnace for connecting carbide furnace
Flue gas sequentially enters cyclone separator to material under the action of air-introduced machine, whirlwind removes for high temperature cabonization cracking generation under anaerobic
Dirt device, deodorization stove, waste heat boiler, overhead steam boiler, air heat exchanger, half-dried chilling tower, Dry absorption device, bag-type dust
Device, air-introduced machine, spray column, absorption tower and chimney.
As a kind of further technical solution, the feeding system includes: storage bin, bucket elevator, feeding passage, feeds intake
Storehouse, the stirring cage that feeds intake, Blowing stopper/unloading valve；The storage bin is set to the bottom of bucket elevator；The top of the bucket elevator is by sending
