Abstract
The utility model relates to an environment-friendly device and aims at providing a medical waste burning fume treatment device which is simple, low in energy consumption, little in maintenance, high in purification efficiency and low in investment cost. As cooling water containing alkali liquor is sprayed in the high-temperature medical waste burning fume, when the fume is cooled down, the alkali liquor and the acid gas in the fume are subjected to chemical reaction to reduce the content of the acid gas, heavy metal and particulate matter; later, the fume with high water content enters a mixer (8) containing slaked lime powder and activated carbon powder through a fume delivery pipe (7); and the fume after further purification enters a bag-type dust remover (9), so that the particulate matter produced in the reaction of the fume is removed by the filtering purification effect by the bag-type dust remover (9) to realize the aim. The medical waste burning fume treatment device has the benefits of being reasonable in design, convenient to maintain, low in energy consumption and capable of effectively avoiding the renewed resynthesis of pollutants such as dioxin and the like; and the purified fume can meet the emission standard.
Description
Technical field
The utility model relates to a kind of environmental protection equipment, is specially a kind of medical waste combustion product gases treatment facility.
Background technology
Medical waste is meant the discarded object that produces in to curative activities such as humans and animals diagnosis, chemical examination, disposal, prevention from suffering from the diseases and research process, having extremely strong infectiousness, biological toxic and corrosivity, is " national hazardous waste register " hazardous waste listed in the text.At present one of effective treatment technology that medical waste is adopted be a burning method, and burning method is one of effective method that destroys infectiousness noxious material, minimizing volume and weight.But the chemical reaction of many complexity will take place in the medical refuse burning process, so contain in the incineration flue gas in a large number to human body and the harmful secondary pollution of environment.Compare with house refuse, the suitable chlorine-bearing compound of quantity is arranged in the medical waste, can reach about 35%, studies show that, the chlorine element is the main source of sour gas hydrogen chloride in the flue gas, and chlorosity easily and the heavy metal generation chemical reaction in the medical waste, generate the chloride that grain diameter is littler, volatility is stronger, for example poisonous and harmful substances such as hydrogen chloride, nitrogen oxide, oxysulfide, volatile heavy metal and dioxin.If without effective processing, these pollutants very likely reenter environment under certain conditions, cause secondary pollution.
Three kinds of wet method, semidry method and dry method are adopted in the gas cleaning that produces for medical refuse burning at present.The shortcoming of wet-treating is that the flue gas after handling needs heating again, and a lot of dissolubility heavy metal salts are arranged in the waste liquid of generation usually, and villaumite concentration must be handled up to 3% again; The shortcoming that semidry method is handled is that equipment is easy to wear, the transit route easy break-down that adopts during processing, and also the operational factor of handling needs strict control; The shortcoming of dry process is that adsorption efficiency and adsorbent utilization rate are low, can increase the pressure that follow-up flying dust is handled.
Summary of the invention
The purpose of this utility model is to provide that a kind of equipment is simple, power consumption less, maintenance is little, purification efficiency is high, cost of investment is low a kind of medical waste combustion product gases treatment facility.
A kind of medical waste combustion product gases of the utility model treatment facility comprises water tank 1, in the described water tank 1 cooling water that contains alkali lye is housed, and a side of water tank 1 is connected with the outlet conduit 2 of water pump 3; The opposite side of outlet conduit 2 is connected flue gas input pipe 4 tops, and the below of described flue gas input pipe 4 is provided with shower nozzle 5, and shower nozzle 5 stretches into quench tower 6, and described quench tower 6 is a conical vessel; The middle part of quench tower 6 one sides is provided with the flue gas delivery pipe 7 of the portion of inserting into the inner, and blender 8 connects carrier pipe 7 and sack cleaner 9, and described sack cleaner 9 can independently be installed institute by many groups cloth bag and constitute; Middle part, the below connecting pipe 10 of blender 8, an other side of pipeline 10 connect defeated powder blower fan 11 of calcium hydroxide and the defeated powder blower fan 12 of active carbon respectively; Be provided with calcium hydroxide warehouse 13 between the defeated powder blower fan 11 of pipeline 10 and calcium hydroxide, described calcium hydroxide warehouse 13 is the back taper container, and its lower end one side is provided with quantitative table 14; Be provided with active carbon warehouse 15 between the defeated powder blower fan 12 of pipeline 10 and active carbon, described active carbon warehouse 15 is the back taper container, and its lower end is provided with quantitative table 14; One side of sack cleaner 9 connects flue gas efferent duct 16, and the bottom connects storage ash bucket 17.
A kind of medical waste combustion product gases of the utility model treatment facility, by in high temperature medical waste combustion product gases, spraying into the cooling water that contains alkali lye, in flue gas cool-down, alkali lye and acidic gas in flue gas generation chemical reaction, reduce acidic gas in flue gas, the content of heavy metal and particle, the flue gas that water content is very high enters the blender 8 that contains calcium hydroxide powder and active carbon powder by flue gas delivery pipe 7 subsequently, enter sack cleaner 9 after further purifying flue gas, remove the particulate matter that reaction is produced in the flue gas through the filtration, purification effect of sack cleaner 9, reach the purpose of materials such as getting rid of sour gas bioxin and heavy metal.Its beneficial effect is that reasonable in design, simple in structure, easy to maintenance, consumed energy is few, the absorption efficiency height, cost of investment is little, can effectively avoid pollutant such as bioxin synthetic more again, flue gas after being purified can reach discharge standard.
