Embodiment 2

[0030] Embodiment 2: The conduit 12 runs through the top of the heat chamber 7 and communicates with the interior of the water storage tank 11, the finned tubes 9 are arranged at equal intervals, and the conduits 12 are symmetrically distributed about the vertical center line of the water storage tank 11 to make the heating more uniform ;

[0031] Specifically, such as figure 1 and figure 2 As shown, hot water can be drawn out along the outlet 10 for domestic or production water, and at the same time, new cooling water is continuously injected from the water inlet 13 to make full use of heat energy, avoid waste of resources, and realize the function of waste heat recovery.

Embodiment 3

[0032] Embodiment 3: The bottom ends of both sides of the hot chamber 7 are provided with a quick ash discharge mechanism 8, and the fast ash discharge mechanism 8 is composed of a fixed plate 801, a protective shell 802, an inspection cover 803, a servo motor 804, and an eccentric wheel 805. The fixed plate 801 is fixedly connected to the bottom end of one side of the heat chamber 7, one side of the fixed plate 801 is fixedly connected with a protective case 802, the inside of one side of the protective case 802 is provided with an inspection cover 803, and one side of the inside of the protective case 802 is fixedly connected with a servo The motor 804, the output end of the servo motor 804 is fixedly connected with the eccentric wheel 805 through a coupling, and the inside of the eccentric wheel 805 is provided with a mounting hole;

[0033] Specifically, such as figure 1 and Figure 5 As shown, when the flue gas dust enters the inside of the hot chamber 7 along the smoke ...

Abstract

The invention relates to a sludge low-temperature drying incinerator with a waste heat recovery function. The sludge low-temperature drying incinerator with the waste heat recovery function comprises a bottom plate, the top end of the bottom plate is fixedly connected with a front end bin, the bottom ends of the two sides of a hot bin are each provided with a rapid ash discharging mechanism, and the other side of the top end of the bottom plate is provided with a feeding anti-blocking mechanism; and a waste heat recovery structure is arranged at the top end of the hot bin. According to the sludge low-temperature drying incinerator with the waste heat recovery function, by arranging finned tubes, a water outlet, a water storage tank, a guide pipe and a water inlet, during use, when sludge is continuously overturned, heated, dried and dewatered in a rotary incineration kiln body, generated smoke and dust can enter the hot bin along a smoke guide pipe on a rear end bin; and the low-temperature finned tubes densely distributed in the hot bin exchange heat with high-temperature smoke, hot water can be led out along the water outlet to serve as domestic or production water, and meanwhile, new cooling water is continuously injected from the water inlet, the waste heat recovery function is achieved, and the problem that the device does not have the waste heat recovery function is solved.

Description

technical field [0001] The invention relates to the technical field of incinerators, in particular to a sludge low-temperature drying incinerator with the function of recovering waste heat. Background technique [0002] Municipal sludge contains a large amount of organic matter and a certain amount of cellulose and lignin, and has a certain calorific value, which makes it convenient for subsequent accumulation, utilization or further processing after being incinerated and dried. There are many types of low-temperature drying incinerators, including multi-chamber incinerators, fluidized bed incinerators, rotary kiln incinerators, grate incinerators, etc. This plan focuses on rotary kiln incinerators, rotary kiln The temperature range of the type incinerator is relatively large, ranging from 810 ° C to 1650 ° C. The temperature control is adjusted by the fuel amount of the burner at the end of the kiln. Usually, liquid fuel or gas fuel is used, and coal powder or waste oil can...
