Embodiment 1

[0024] Embodiment 1 In Figs. 1 and 2, a vertical domestic waste thermal decomposition incinerator includes an incinerator body 3, a hopper and a feeding bin 1 at the front end of the incinerator body 3, and a slagging device 4 at the rear end; its features In that: a stepping feeding device 2 is provided at the front end of the hopper and feeding bin 1; the feeding device 2 is a stepping conveyor, mainly including a conical hopper, a trough, a horizontal stepping plate 12, a hydraulic drive device 10 and a hot air Composed of drying chamber 13; the top of horizontal stepping plate 12 is connected with conical hopper 1, and the bottom is provided with hot air drying chamber 13; horizontal stepping plate 12 is connected with push rod mechanism 9 on roller bracket 11 and driven by hydraulic drive device 10, The rubbish is pushed into the discharge port 14 in a step-by-step manner. In view of the problem that the 100t / d vertical thermal decomposition furnace that has been put into...

Embodiment 2

[0026] Example 2 A vertical domestic waste thermal decomposition incinerator, in which the hot air drying chamber 13 is connected to the flue gas air preheater in the tail flue of the boiler body of the incinerator body, and the hot air for drying is introduced. All the other are with embodiment 1. The waste heat of the flue gas is used to heat the cold air, and the heated hot air is supplied to the walking garbage conveyor. Hot air can be used as its backup hot air source. Using the waste heat of the flue gas can reduce the exhaust gas temperature and improve the efficiency of the boiler.

Embodiment 3

[0027] Example 3 A vertical domestic waste thermal decomposition incinerator, wherein the slag removal device 4 adopts a hydraulic bucket arm type slag discharger; its structure is that the bottom of the air inlet pipe 5 is water-sealed at the bottom of the tank 7 below the outlet of the ash hopper A dust-scraping board 6 is set, and the dust-scraping board 6 is driven by a bucket arm type connecting rod transmission mechanism 8 . As shown in Figure 1. General waste incineration devices such as grate furnaces and circulating fluidized bed furnaces use hydraulic arc-shaped push plate slag machines or chain plate slag machines. Because the vertical rotary pyrolysis waste incinerator has a conical ash hopper at the lower part of the furnace body inserted into the water seal tank, and the primary air pipe of the first combustion chamber passes through the center of the conical ash hopper and then enters the air under the rotary grate. chamber, the slag falls into the water from t...

Abstract

The invention discloses an upright life waste thermal decomposition incinerator, comprising a body, a hopper and a feeding chamber at the front of the body, and a slag outlet at the back end, a feeder at the front end of the hopper and the feeding chamber. The feeder is step feeder formed by a taper hopper, a groove, a horizontal step plate, a hydraulic driver and a hot wind drying room. The horizontal step plate is connected with the taper hopper above and the hot wind drying room under, while it is driven by the hydraulic driver, to stepped push waste into an outlet. The hot wind drying room is connected with a smoke air preheater in the tail smoke channel of the boiler. The slag outlet is hydraulic arm slag outlet device, which arranges a slag scrape plate at the bottom of the water sealing groove at the bottom of lower wind inlet tube under a slag hopper, while the plate is driven by an arm connecting rod transmitter. The invention can be used in high-water low-heat waste incinerator.

Description

technical field [0001] The invention relates to an incinerator in energy and environmental protection equipment, in particular to a domestic garbage incinerator. It can be especially used for incineration of low calorific value, high moisture, unsorted household waste incineration to generate electricity. Background technique [0002] With the development of modern production, the increase of urban population and the improvement of consumption level, the generated garbage pollutes the environment and causes social public hazards, which has already attracted the attention of all countries. At present, there are two major types of municipal solid waste disposal methods, namely incineration and sanitary landfill. The latter occupies a large amount of land and its leachate pollutes more groundwater, and the landfill causes secondary pollution to the surrounding environment. Most foreign countries use waste incineration to achieve the purpose of reduction, harmlessness and reso...
