Abstract
The utility model relates to a medical waste disposing incinerator. The utility model essentially consists of a material inlet, a once combustion chamber, a secondary combustion chamber, a combustor, a flue, a once air duct, a secondary air duct, a thermometer hole and a desulphurization and antichlor injecting entrance. The incinerator is designed to a once combustion chamber and a secondary combustion chamber. The two combustion chambers are provided with a combustion supporting combustor with intelligent control to intelligently control the combustion temperature of the combustion chamber. Multilevel and multiply whirlwinds are arranged on the four walls of the combustion chamber. The pathogenic bacteria of the medical waste can be completely wiped out. The burning efficiency of the burning residue is below five percent. The utility model has the advantages of excellent burning capability, high ability of unit disposing, high degree automatization, full burning, no strict requirements to the moisture size and calorific value of the medical waste, and is applied to intraday produced medical waste on-site processing, and can be used as household waste disposing incinerator.
Description
(1) technical field: refuse treatment plant.
(2) technical background: along with growing with each passing day and the raising of living standards of the people of progress, the urban population of expanding economy, society, the pollution of China's clinical waste becomes increasingly conspicuous.Owing to contain pathogen such as a large amount of germs, virus and parasite in the clinical waste,, environment and human life and health caused serious harm if management or mishandling very easily causes viral pollution.China classifies clinical waste as hazardous waste, and regulation must be carried out harmless treatment to clinical waste.
The processing mode of clinical waste mainly contains sanitary landfill method, sterilization method and burning method.The sanitary landfill method treating capacity is big, convenient and easy, yet because the particularity of clinical waste directly adopts landfill disposal also to have many problems.Carrying out landfill with domestic garbage mixing, then is the disposal options that China's law is expressly forbidden.The sterilization method is a kind of conventional treatment mode of MEDICAL WASTE TREATMENT, adopt the sterilization of physical disinfection or chemical agent, have convenience, practical characteristics, but because the completeness that various sterilization technologies have certain selectivity and are difficult to guarantee sterilization for the clinical waste of handling, and the use of a large amount of medicaments also has certain negative effect, and China's health ministry does not advocate whole employing of clinical waste disinfected.
It is thorough that burning method has sterilization, easily operation, decrement subtract hold big, secondary pollution can be controlled, burn the innoxious degree advantages of higher of back residue for the favor of world developed country, also be able to apply in developing country.The hospital refuse incinerator of China's production at present sees have and fire formula again with regard to its type of furnace, rotate the charging tray formula, pyrolysis reverse combustion type etc.Owing to start late, the operating period is short, still needs and further strengthens studying, and improves design, improves the dynamics of incinerator quality and increase series of products, improves the scientific and technological content of incinerator, could satisfy the requirement that medical wastes incineration is handled.Therefore, we have proposed multiply whirlwind medical wastes incineration stove, present technique has absorbed the advantage of international advanced technology, consider that simultaneously China has the not good shortcoming of medical wastes incineration stove treatment effect now, furnace type structure, supply air system and the auxiliary combustion equipment of incinerator designed and innovate, be more suitable in clinical waste is carried out burning disposal.This technology not only can effectively subtract appearance, decrement to rubbish, and can also reach sterilization and the generation that suppresses noxious material in the burning process completely.
The utility model is designed to primary zone and secondary combustion chamber to incinerator, carry out multistage multiply whirlwind for combustion air and be arranged in the combustion chamber wall, simultaneously once, secondary combustion chamber disposes the combustion-supporting combustor of band Based Intelligent Control respectively, controls the combustion chambers burn temperature automatically.Clinical waste directly burns under the effect of multistage multiply whirlwind in the primary zone, pathogen in the clinical waste is utterly destroyed and effective generation that suppresses harmful substance in the burning, the hot burn decrement rate of incineration residue is below 5%, and burning is thorough, 850 ℃～1100 ℃ of incineration temperature controls; The flue gas that burns generation in the primary combustion enters in the secondary combustion chamber and fires under the strong disturbance of intensification and multiply whirlwind at the intelligent combustion machine aided, the burning indoor temperature is controlled at 1100 ℃～1300 ℃ high temperature, fuel gas in the flue gas is able to completing combustion, simultaneously, under the effect of desulfurization, antichlor, significantly reduced the harmful substance in the flue gas.
