Problems solved by technology

At the same time, the combustion-supporting air is only injected from the kiln head, and it basically tends to laminar flow at the end of the kiln, and the disturbance is not obvious, which is not conducive to the full combustion of materials in the kiln.
Therefore, in order to ensure a constant kiln head temperature in operation, it is necessary to assist a large amount of additional fuel for heating, resulting in increased operating costs

Embodiment 1

[0026] Embodiment 1: as figure 1 and figure 2 As shown, the multi-stage combustion rotary kiln used in the waste incineration project of the present invention includes a rotary kiln body 1, and one end of the rotary kiln body 1 is provided with a kiln head air supply port 2, a kiln head feed port 3 and a burner 13. The other end of the kiln body 1 is provided with a kiln tail discharge port 4 , and the kiln tail discharge port 4 includes a kiln tail smoke outlet 401 and a kiln tail slag discharge port 402 . Along the axial direction of the rotary kiln body 1, more than one air supply section is sequentially provided on the middle section of the rotary kiln body 1, each air supply section is provided with more than one middle section air supply port 5, and on the same air supply section A plurality of air supply ports 5 in the middle section are evenly arranged along the outer circumferential direction of the rotary kiln body 1 . The number and location of the air supply sec...

Embodiment 2

[0035] Embodiment 2: as image 3 and Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that: the middle air supply ports 5 on each air supply section are connected with a centralized air supply pipe 10, and in this embodiment, all the middle air supply ports The tuyere 5 is all connected with a centralized air supply pipe 10, and the air inlet end of the centralized air supply pipe 10 is connected with the middle section air supply fan 9, that is, the centralized air supply control is adopted through the centralized air supply pipe 10. The centralized air supply pipe 10 is annularly arranged on the outer peripheral side of the rotary kiln body 1 , and its inlet end communicates with the middle air supply fan 9 through a fixed pipe 11 and a seal 12 . The middle stage air supply fan 9 is installed on the ground outside the rotary kiln body 1 .

Abstract

The invention discloses a multi-stage combustion rotary kiln for waste incineration projects, comprising a rotary kiln body, wherein one end of the rotary kiln body is provided with a kiln head air supply opening and a kiln head feeding opening, and the other end of the rotary kiln body is provided with a kiln tail discharge opening; along the axial direction of the rotary kiln body, the middle section of the rotary kiln body is provided with more than one air supply fracture surface in order, and each of the air supply fracture surfaces is provided with more than one middle section air supply opening. The multi-stage combustion rotary kiln is simple and compact in structure, low in cost, good in combustion effect, stable and reliable in work, good in energy saving performance and the like.

Description

technical field [0001] The invention mainly relates to the field of garbage incineration engineering equipment, in particular to a rotary kiln suitable for garbage incineration engineering. Background technique [0002] At present, rotary kiln technology is widely used in waste incineration projects in my country, especially for hazardous waste incineration projects and medical waste incineration projects with a scale of more than 10 t / d. Rotary kiln technology is the first choice for incineration equipment. The rotary kiln equipment used for incineration is mostly short and fat kiln structure, and the configuration is usually in the downstream mode for easy operation. The waste to be incinerated, the burner and the air duct required for combustion in the kiln are all arranged at the front end of the kiln head, and all are supplied by the kiln head. [0003] Since all kinds of wastes have a certain calorific value, and some wastes have a high calorific value. For example, t...
