Description

Device for continuous oxygen-free carbonization of organic waste with superheated steam

technical field

The invention relates to the technical field of organic waste treatment equipment, in particular to a device for continuous anaerobic carbonization of organic waste with superheated steam.

Background technique

At present, the level of carbonization technology in my country is simple and single, and it is mostly used for the carbonization of biomass, such as the carbonization of organic matter such as wood, straw, rice husk, and coal. The carbonization effect of carbides is not very demanding. With the rapid development of China's chemical, pesticide, pharmaceutical and other industries, a large amount of hazardous organic waste is produced every year. Many wastes can be destroyed by simple incineration of pollutants that are difficult to degrade, but at the same time, a large amount of highly toxic gas dioxin will be produced. British and residue, fly ash and other waste.

The world produces more than one billion tons of organic waste every year. In 2015, my country’s hazardous waste production exceeded 60 million tons. As of 2011, there were about 1,500 units with hazardous waste business licenses nationwide, and the annual disposal volume of hazardous waste was only It can exceed 9 million tons, and the disposal capacity and disposal technology are far from satisfying the status quo. At the same time, the incineration technology cannot completely dispose of all hazardous waste. For example, the incineration of high-salt organic waste will shorten the service life of the incinerator. Therefore, the organic waste disposal industry urgently needs to introduce more new technologies.

At present, the existing carbonization technology has many defects in the processing of machine waste, and the objective shortcomings are as follows:

1. The way of the existing superheated steam carbonization furnace

The saturated steam enters the heat accumulator, vapor-liquid separator, superheating furnace, turbogenerator and deaerator in sequence. Dispose of organic waste.

2. External heating continuous carbonization organic waste device

Using electric heating to burn biomass fuel or heating heat medium to heat the carbonization furnace externally, these devices have common disadvantages: high energy consumption; Issues such as sealing and thermal media leakage.

3. External heating (or internal heating) batch type carbonization device

The disadvantages of this device are: the fixed treatment capacity is small each time; the time is long; the treatment efficiency is very low; most of the waste gas generated by the batch carbonization device is directly discharged into the atmosphere, polluting the environment, or as a simple waste gas treatment device, the effect is general .

4. Internal heating continuous carbonization device

The disadvantage of using heated air to carbonize the materials in the carbonization furnace is that the hot air is rich in oxygen, so the organic waste cannot be carbonized in the true sense without oxygen. The hot air is rich in oxygen, and it is easy to burn when exposed to organic waste. Many organic substances have very low melting points, so once certain organic substances melt, they will damage the carbonization furnace body and its internal conveying devices.
