Combination fire grate vaporization incinerator

Abstract

The invention discloses a combination fire grate vaporization incinerator. The combination fire grate vaporization incinerator comprises a hopper, a vaporizing chamber, a combustion chamber and a tailportion flue. Two sides of the vaporizing chamber are arranged obliquely and a slag-falling channel is formed by contracting the bottom of the two sides of the vaporizing chamber, and a water seal tank is formed in the bottom end of the slag-falling channel. The vaporizing chamber is internally provided with a middle arch which is arranged obliquely, and the vaporizing chamber is divided into a vaporizing area provided with a communicating vaporizing air channel on the upper portion and a vaporizing combustion area. The combustion chamber is arranged above the vaporizing combustion area. A combination fire grate is arranged on an inclined side of the vaporizing area, the starting end of the combination fire grate is located below the hopper, and the tail end of the combination fire grateis connected with the slag-falling channel. The combination fire grate at least comprises a first-stage fire grate and a second-stage fire grate which are arranged in a ladder mode. The top of the vaporizing combustion area and the combustion chamber are arranged in a shape like a Chinese character 'ao', the extending section of the vaporizing air channel and the combustion chamber are separatelylocated at platforms at two sides of the Chinese character 'ao', and the concave part of the top of the vaporizing combustion area forms a side baffle wall of the vaporizing air channel. The combination fire grate vaporization incinerator is subjected to vaporizing first and then burnt and two stage combustion, and has the advantages of wide fuel adaptability and good initial emission of flue gas.

Description

technical field [0001] The invention relates to a gasification incinerator for a combined furnace, which belongs to the sub-field of gasification and incineration of garbage in the field of environmental protection. Background technique [0002] With the process of urbanization and the expansion of scale, the increase of urban population, the opening of the market, the change of residents' consumption structure and the development of tourism, the generation and accumulation of urban garbage have increased year by year. 156 million tons, while in 2016 the volume of domestic waste removal has reached 204 million tons. The growth rate of waste removal volume is much faster than expected. [0003] Garbage incineration is the most preferred way of solid waste reduction and recycling / harmless treatment. Furnace types used for waste incineration include grate furnace, rotary kiln, circulating fluidized bed, pyrolysis furnace, etc. The development of waste incineration technology...

Problems solved by technology

More importantly, for my country's high-moisture, low-calorific value waste, if the layer combustion technology does not use oil to support combustion, the pollution emissions will be high. If oil is used, the operating cost will be quite high and the economy will be poor.
