Abstract
The utility model relates to an abnormal odor catalytic oxidizer for treating town household garbage, which comprises an intake and exhaust heat exchange structure, an electric heating device, a supported catalyst, a heat insulator and a temperature control device. The intake and exhaust heat exchange structure comprises an inner barrel and an outer barrel; the outer barrel is used as a shell; one end of the outer barrel is provided with a gas inlet and the other end of the outer barrel is provided with an end cover; spiral blades for gas flow guiding are arranged on the peripheral surface of the inner barrel; gas flow guide blades are radially arranged on the end face of the inner barrel; one end of the inner barrel is provided with an exhaust port and the other end of the inner barrel is provided with a ring-shaped end cover; the exhaust port extends out of the outer barrel; a catalytic oxidization chamber and a waste gas cooling passage are formed in the inner barrel; a fixed bracket is arranged on the end cover of the outer barrel; the electric heating device and the supported catalyst are arranged at intervals on the fixed bracket; the temperature control device comprises a controller and a thermocouple; the controller is connected with the electric heating device; the thermocouple is arranged in the catalytic oxidization chamber; the thermocouple is connected with the controller by a line. Utilization of the abnormal odor catalytic oxidizer for treating town household garbage can effectively solve the problem of environmental gas abnormal odor at household garbage treatment process points and in treatment workshops.
Description
Technical field
The utility model relates to a kind of catalytic oxidizer, especially relates to a kind of foreign odor catalytic oxidizer for application of city life garbage processing.
Background technology
The foreign odor harm of the collection of application of city life garbage, storage, transhipment, processing procedure is the technical barrier that allows people have a headache all the time.
House refuse complicated, mostly contain kitchen excess, content of organics is higher, and often there are a large amount of pathogen microorganisms and parasite and heavy metal element, its organic matter is corrupt under microbial action can go out various foreign odor gas by sustained release, these foreign odor gas ingredients are conventionally complicated, Main Ingredients and Appearance is roughly sulfur-containing compound, as hydrogen sulfide (gaseous state), methyl mercaptan (approximately 36 DEG C of boiling points), butyl mercaptan (approximately 122 DEG C of boiling points), tert-butyl mercaptan (approximately 64 DEG C of boiling points), propanethiol (approximately 68 DEG C of boiling points), propylene mercaptan (approximately 67 DEG C of boiling points), amyl hydrosulfide (approximately 123 DEG C of boiling points), beneze methane thiol (approximately 195 DEG C of boiling points), benzenethiol (approximately 168 DEG C of boiling points), p-benzyl mercaptan (approximately 43 DEG C of boiling points), sulfur dioxide (gaseous state), methyl disulfide (approximately 109 DEG C of boiling points), carbon disulfide (approximately-30 DEG C of boiling points) etc., nitrogen-containing compound, as ammonia (gaseous state), methylamine (approximately-6.8 DEG C of boiling points), ethamine (approximately 16.6 DEG C of boiling points), dimethylamine (approximately 6.9 DEG C of boiling points), trimethylamine (approximately-4 DEG C of boiling points), hydrazine (approximately 119 DEG C of boiling points), butylamine (approximately 44 DEG C of boiling points), Beta-alanine (approximately 198 DEG C of boiling points), beta-amino propyl alcohol (approximately 188 DEG C of boiling points), indoles etc., halogen and halogenated hydrocarbons, hydro carbons and aromatic hydrocarbon, oxygen-bearing organic matter, as alcohol, phenol, aldehyde, ketone etc.Wherein particularly evident with the toxicity of hydrogen sulfide, people is at 70~150mgH
2s/m
3in environment approximately 1 hour, there is irritation in respiratory tract and eyes, suck approximately 5 minutes after olfactory fatigue and do not hear that it is smelly; People is at about 300mgH
2s/m
3in environment approximately 8 minutes, there is acute irritation symptoms in eyes, causes that slightly for a long time pulmonary edema, bronchitis cause pneumonia, occurs that headache and dizziness feels sick; People is at 1000mgH
2s/m
3in environment can there is acute poisoning in the several seconds, and after accelerated breathing, respiratory paralysis is lethal.
Current, the method that solves house refuse foreign odor both at home and abroad can be summarized as: essence encapsulation method, and fragrant essence is covered foreign odor, but can not reduce foreign odor composition, local Dilution air method, arranges with blower fan exhausting dilution indoor stink or directly, still causes the pollution to external environment condition, solid matter absorption method, extract the just discharge after adsorbing with solid matters such as activated carbon, carbonate compound, zeolite, inorganic halides in special arrangement of foreign odor gas out with blower fan, with the degree that reduces externally to pollute, but effect depends on foreign odor molecular species, content, and active carbon etc. was easily because the little molecule foul odor poisoning of part was lost efficacy, Ozonation, i.e. Bian ozone oxidation H
2s and NH
3, effect depends on ozone concentration, but ozone itself just has a kind of stink, and ozone concentration reach 125PPM by harm people's health, affect surrounding environment, and the oxidizable inefficacy of the high-field electrode of ozone generator needs to regularly replace, effective microbe method, optimize and choose the high concentration that contains multiple occurring in nature, highly active efficacious microbial colony or yeast flora are cultivated, cloth is spread in house refuse, allow these microbial bacterias suppress to cause in rubbish the biochemistry activity of smelly microorganism, and utilize the nutrition of some stink thing as self, to reduce the rotten speed of rubbish and reeky foreign odor degree thereof, the current stable and reliability of the method still needs further to be studied, health effect international academic community to people also there is no final conclusion, and for be foreign odor source, instead of foreign odor molecule itself, inoperative to established foreign odor, also because of the installations and facilities of the large corrosion treatment of its solution acidic, plant extraction liquid catalytic oxidation, utilizes some natural botanical extraction liquids to destroy the character of hydrogen sulfide, mercaptan, ammonia, amine, aldehyde foul smell molecule, and through reaction, foul smell molecule generates the nontoxic product of odorless, and the method raw material sources are still limited and cost is still very high, negative pressure is collected into incinerator burning method, and the method is effective, but application often shown limitation, each operation point of domestic rubbish disposal process, during especially without large-scale incinerator and the operation point of dispersion and movement operation point be difficult to processing.
The said method application of house refuse deodorizing both at home and abroad has all obtained significant achievement, but resident and garbage disposal worker are still perplexed in the foreign odor of house refuse and harm, therefore, in the urgent need to a kind of rapidly and efficiently, house refuse foreign odor processing method and the treating apparatus of wide adaptability, solve the problem that affects of house refuse foreign odor from each operation point source and environment.
