Vertical precombustion furnace, horizontal rotary furnace and vertical discharging device combined garbage incinerator

Abstract

The invention discloses a vertical precombustion furnace, horizontal rotary furnace and vertical discharging device combined garbage incinerator. A vertical precombustion furnace (14), a horizontal rotary furnace (6) and a vertical discharging device (8) are connected through a kiln head rotary sealing device (3) and a kiln tail rotary sealing device (7) so as to form an L-shaped garbage incinerator. Because the length of the horizontal rotary furnace is shortened and the vertical precombustion furnace and the vertical discharging device are arranged vertically, the L-shaped garbage incinerator has the characteristics of minimum volume, small occupied area and low heat loss. Meanwhile, because the vertical precombustion furnace and the vertical discharging device are relatively stationary, the relative rotation of the horizontal rotary furnace can be effectively guaranteed, and the sealing property of the L-shaped garbage incinerator is also guaranteed simultaneously. The garbage incinerator is suitable for incineration treatment of a variety of garbage, particularly household garbage, can replace mechanical discharging furnaces, fluidized beds, rotary kilns and other incinerationequipment, and is suitable for incineration treatment of unclassified garbage in China.

Description

Technical field [0001] The invention belongs to the technical field of garbage treatment equipment, in particular to a garbage incinerator combined with a vertical pre-combustion furnace + a horizontal rotary furnace + a vertical discharger. Background technique [0002] The disposal of all kinds of garbage, especially domestic garbage, is an urgent problem for the whole society today. The state has clearly put forward the garbage disposal principle of "harmlessness, reduction, and resource utilization". [0003] At present, there are several methods of garbage disposal, incineration, landfill and biological methods. [0004] The landfill method is the most commonly used method for domestic garbage disposal in my country. It not only takes up a large amount of land and forms a situation of "garbage encircles the city", but also pollutes groundwater sources for a long time. [0005] Biological method can treat part of the decomposable garbage well, but the non-decomposable part needs t...

AI Technical Summary

Problems solved by technology

[0010] There is also the use of incinerators in thermal power plants for waste disposal, but a large amount of coal is required as fuel in the incineration process

[0011] There is also the use of rotary kilns to treat waste, but the diameter and length of the rotary kiln system are large, the floor area is large, the civil construction costs are high, and the heat loss of the system is also large.

[0012] The waste incinerator composed of vertical pre-combustion furnace + horizontal rotary furnace + vertical discharger has not been reported so far
