Description

Environmental protection disinfection medical waste incinerator

technical field

The utility model relates to a medical waste incinerator.

Background technique

Existing medical waste incinerators only consider combustion and dust removal, and there is generally a problem of insufficient control over the emission of dioxin toxicity. Dioxin is easy to cause cancer and is very harmful to human health. On June 16, 2003, Premier Wen Jiabao of the State Council of my country issued a government order requiring the nationwide implementation of centralized incineration of medical waste to prevent the spread of viruses. Therefore, how to effectively control the discharge of dioxins in the incineration process is a top priority.

Contents of the invention

The purpose of the utility model is to provide an environmentally friendly and disinfected medical waste incinerator capable of meeting dioxin discharge standards, protecting human health, and solving the technical problems that the incinerator cannot effectively control dioxin emissions due to insufficient combustion.

The technical scheme of the utility model environment-friendly disinfection medical waste incinerator: the top of the main combustion chamber is connected with the flue, and the main combustion chamber has a built-in grate. Heater, cold air cooler and dust collector. The air preheater is connected to the main combustion chamber through the air pipe, fan and cross air pipe in turn. The cold air cooler is connected to the cold air supply machine. Connected, the igniter is connected above the grate of the main combustion chamber, and the ash tank is connected below the grate of the main combustion chamber.

The above-mentioned main combustion chamber is a shape with a big bottom and a small top.

The above-mentioned air preheater communicates with the lower part of the furnace of the main combustion chamber through the air duct, the blower fan and the cross air duct successively.

Beneficial effects: the working process of the utility model: after putting the medical waste into the main combustion chamber, use the igniter to ignite it, start the fan to make the waste start to dry distillation and gasify, and the combustible gas can achieve secondary combustion through the upper combustion aid, and achieve the goal of eliminating waste. The purpose of smoke, at this time, the temperature is 850-1000 ℃ high temperature, when the flue gas passes through the air preheater, one is to cool down the flue gas, and the other is to heat the air for combustion. The high temperature flue gas discharged by the air preheater passes through the cold wind When the temperature is lowered, it quickly drops below 150°C, and it only takes 0.8 seconds for the above working process to drop from 850-1000°C to below 150°C. Therefore, the formation and discharge of dioxins are effectively controlled. The utility model has the following characteristics:

1. The air at normal temperature directly enters the cold air cooler through the cold air supply machine and mixes with the high-temperature gas in the flue.

2. The hearth of the main combustion chamber adopts a bottom-large and upper-small structure and a retort gasification combustion method to speed up retort gasification.

3. The hot air heated by the air preheater is directly sent to the lower part of the furnace by the fan for primary combustion, and an oxygen-supplementing burner is installed at the top of the main combustion chamber for secondary combustion, so that the combustible gas can be fully burned for the second time. An air preheater is installed on the flue to increase the temperature of the air for combustion.

4. There is a dust collector at the tail, which has a good smoke and dust removal effect.

In the utility model, due to dry distillation, gasification, oxygen supplementation and secondary combustion, high-temperature disinfection, rapid cooling, and reduction of smoke and dust. Its advantages are: full combustion, no black smoke, smoke and dust emission up to the standard, the biggest advantage is that it can effectively prevent the generation and emission of dioxins and ensure human health. It is an incinerator that can replace imported ones, which can greatly reduce investment costs. The utility model is environmentally friendly, and the sterilized medical waste incinerator can be widely used for medical waste incineration.

Detailed ways

As shown in the figure, this kind of medical waste incinerator consists of ash tank 1, igniter 2, main combustion chamber 3, oxygen supplement burner 4, flue 5, air preheater 6, cold air cooler 7, fan 8, A cold air supply machine 9, a dust collector 10, a flue outlet 11, and a fire grate 12 are formed. Igniter 2, oxygen-supplementing combustor 4, air preheater 6, cold air cooler 7, blower fan 8, cold air feeder 9, dust remover 10 all can adopt existing equipment. The igniter 2 can be used to ignite the garbage, and the fan 8 sends the air heated by the air preheater directly to the main combustion chamber 3 and the oxygen-supplementing combustion aid 4, so that the upper part of the main combustion chamber can be fully burned by retort gasification, and the high-temperature flue gas passes through the smoke Road 5 enters the air preheater 6, and the air sucked by the fan is heated through the horizontal air pipe 13, and the cold air blown in by the cold air supply machine 9 is mixed with the high-temperature flue gas in the flue by the cold air dehumidifier 7, so as to achieve the purpose of rapid cooling. Finally, dust is removed by dust collector (wet method).
