Embodiment 1

[0026] according to figure 1 and figure 2 , a new type of high-temperature-resistant garbage incinerator, which includes a body of furnace 3 and ash box 9; The fire grate includes a bracket 6 and a plurality of hollow bars 7 that run through the bracket; the hollow bars 7 are connected in series through elbows; A water outlet 16 and a water outlet 17; the support 6 is vertically connected to the side wall of the furnace body 3, and a reinforcing plate 13 is provided below the joint; a closing plate 12 is provided above the support.

[0027] During the combustion process, the hollow grate 7 starts water circulation through the water inlet 16 and the water outlet 17, which effectively prevents the grate from being burned out, and the circulating hot water can also be recycled.

[0028] A smoke pipe 1 is provided on the furnace body 3, and an air inlet pipe 8 is provided in the ash box 9.

[0029] The body of furnace 3 is provided with an inspection door 11 , and the ash box ...

Embodiment 2

[0037] The hollow furnace bars used in high-temperature-resistant garbage incinerators are prepared according to the following process:

[0038] Take Cu-Fe master alloy (CuFe10) 1000kg, Cu-Cr master alloy (CuCr10) 200kg, Cu-Mn master alloy (CuMn30) 50kg, Al-Ti-B master alloy (AlTi5B1) 10kg; put them into the electric melting furnace in turn, Raise the temperature, control the melting temperature to 1200°C, after 3 hours of melting, take out the prepared melt, pour it into the mold, cool to 800°C at a cooling rate of 40°C / s, keep it warm for 100s, and then heat it at 25°C / s Cool to 300°C, keep warm for 200s, then cool to room temperature at a speed of 20°C / s, demould to get the blank; heat the blank to 500°C, heat up at a rate of 2°C / s, keep warm for 2 hours, and then Cool down to 400°C with a cooling rate of 5°C / s and keep warm for 5 hours, then raise the temperature to 450°C with a heating rate of 2°C / s and keep warm for 4 hours, then cool down to 300°C with a cooling rate of...

Embodiment 3

[0040] The performance test of hollow furnace bar alloy material of the present invention:

[0041] Set up control groups, control group 1: no addition of Al-Ti-B master alloy, the rest is the same as in Example 2; control group 2: no addition of Cu-Mn master alloy, the rest is the same as in embodiment 2. The performance parameters of each group are shown in Table 1:

Abstract

The invention discloses a novel high-temperature resistance garbage incinerator. The novel high-temperature resistance garbage incinerator includes an incinerator body and a ash collection box; the ash collection box is arranged under the incinerator body; a fire grate is arranged between the ash collection box and the incinerator body; the fire grate includes a support and a plurality of hollow fire bars, wherein the fire bars penetrate through the support; the fire bars are in serial connection through bent pipes; the two ends of each fire bar stretch out of the outer side of the incineratorbody and are provided with a water inlet and a water outlet respectively; the support and the side wall of the incinerator body are connected perpendicularly and reinforcing plates are arranged underthe joint; closing plates are arranged on the support. The novel high-temperature resistance garbage incinerator is reasonable in structure; by conducting water circulation on the fire bars inside the fire grate, the temperature of the fire bars is reduced, the fire bars are prevented from deforming and cracking due to incineration, and the technical problems are effectively solved that in the prior art, fire grates of garbage incinerators are not resistant to incineration and not convenient to use.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration, and in particular relates to a novel high-temperature-resistant garbage incinerator. Background technique [0002] With the development of society, there are more and more domestic wastes, and the recyclable part of the domestic wastes is recycled, while the remaining part is incinerated in the incinerator. [0003] There are horizontally distributed fire grates in the incinerator, and the fire grate is welded with iron bars distributed horizontally and vertically. Because the garbage contains a lot of plastic and other substances, it will corrode the metal material after melting. When burning, it will stick to the grate and burn, and the grate will also bear the weight of the garbage, which will cause the grate to bend and break. Use The service life is short; when adding raw materials, it is easy to accumulate on the edge of the furnace body, resulting in adhesion to the furnace b...
