Description

Technical Field

[0001] The utility model belongs to the technical field of hazardous waste treatment equipment and relates to a rotary kiln for hazardous waste incineration. Background Art

[0002] Solid hazardous waste is often incinerated using a rotary kiln. The rotary kiln is in a slow rotation state. The hazardous waste to be crushed is fed into one end of the kiln, and a gas burner is arranged at the feeding port. After the material is crushed into a fluid, it is discharged from the end of the kiln. Since the inner wall of the kiln is formed by laying refractory bricks, it needs to be regularly maintained and repaired. During the incineration process, lumps are also likely to form at the end of the kiln, which also needs to be regularly cleaned. In the prior art, when maintaining and cleaning the kiln, the fire needs to be stopped to cool the kiln, which takes a long construction period, causes serious energy consumption loss, and cannot realize continuous incineration treatment of hazardous waste. Content of the Utility Model

[0003] The purpose of the utility model is to provide a rotary kiln for hazardous waste incineration aiming at the above problems existing in the prior art. The technical problem to be solved by the utility model is how to avoid stopping the fire of the kiln.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A rotary kiln for hazardous waste incineration, characterized in that it includes a discharge tower and two incineration units symmetrically distributed at both ends of the discharge tower. The incineration unit includes a ground rail, a support slidably connected to the ground rail, and a furnace body rotatably connected to the support. The discharge tower includes a jack corresponding to the furnace body. The discharge end of the furnace body is inserted into the jack, and a slag discharge port is arranged at the lower end of the discharge tower.

[0005] Further, a chimney is connected to the top of the discharge tower.

[0006] During normal operation, the two incineration units can choose to work simultaneously, or one of the furnace bodies can be selected to be in a working state according to the incineration amount, and the other furnace body slides away from the discharge tower through the ground rail. The jack on the discharge tower is temporarily blocked due to the separation of the furnace body. The advantage of this incineration kiln is that one or two furnace bodies can be selected to work according to the incineration amount, and the two furnace bodies can be regularly repaired alternately to ensure the continuous progress of the incineration work. Description of the Drawings

[0007] Figure 1 It is a schematic structural diagram when one of the incineration units is in an idle state.

[0008] Figure 2 It is a schematic structural diagram when both are in a working state.

[0009] In the figure, 1, discharge tower; 2, ground rail; 3, support; 4, furnace body. Detailed Embodiment

[0010] The following are specific embodiments of the present utility model, and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described. However, the present utility model is not limited to these embodiments.

[0011] As Figure 1 and Figure 2 shown, the rotary kiln furnace for hazardous waste incineration includes a discharge tower 1 and two incineration units symmetrically distributed at both ends of the discharge tower 1. The incineration unit includes a ground rail 2, a support 3 slidably connected to the ground rail 2, and a furnace body 4 rotatably connected to the support 3. The discharge tower 1 includes a jack corresponding to the furnace body 4. The discharge end of the furnace body 4 is inserted into the jack. A slag discharge port is provided at the lower end of the discharge tower 1, and a chimney is connected to the top of the discharge tower 1.

[0012] During normal operation, the two incineration units can be selected to work simultaneously, or one of the furnace bodies 4 can be selected to be in a working state according to the incineration amount, and the other furnace body 4 slides away from the discharge tower 1 through the ground rail 2. The jack on the discharge tower 1 is temporarily blocked due to the separation of the furnace body 4. The advantage of this incineration kiln furnace is that one or two furnace bodies 4 can be selected to work according to the incineration amount, and the two furnace bodies 4 can be regularly repaired in rotation to ensure the continuous progress of the incineration work.

[0013] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
