Embodiment Construction

[0036] A method and system for treating and utilizing phenol water using a rotary kiln, such as Figure 1 to Figure 3 As shown, it involves a rotary kiln 1, a phenol water tank (box) 2, an electric pump 3, a pipeline 4, and a nozzle 5.

[0037] Among them, the rotary kiln 1 can be divided into cement rotary kiln, burnt gemstone rotary kiln, kaolin rotary kiln, lime rotary kiln, etc. according to the purpose. There are a large number of fired products in this type of rotary kiln in the factory, and the fired products generally need to be cooled. . The following is an example of a rotary kiln for burnt gemstones.

[0038] The rotary kiln 1 includes the kiln head part 11 (kiln head cover), the kiln body part 12 and the kiln tail part, wherein the kiln head is the discharge part of the rotary kiln, the diameter is larger than the diameter of the rotary kiln, and the seal is realized by stainless steel scales and the kiln body. Body part 12 is the main body of the rotary kiln (ro...

Abstract

The invention provides a method and system for processing and utilizing phenol water through a rotary kiln. Firstly, a spraying pipe is installed in a kiln head of the rotary kiln and connected to a phenol water tank through a pipeline and a pump, the spraying pipe is provided with water spraying holes spraying water upwards, the phenol water falls onto sintered articles discharged out of the rotary kiln after being sprayed out and atomized so that phenol water mixed steam can be formed, under the driving of negative-pressure airflow, in the forward direction, the phenol water mixed steam sequentially passes through a cooling zone, a sintering zone and a preheating zone in the kiln, and finally, the phenol water mixed steam is discharged. The phenol water is processed under the high-temperature environment of the rotary kiln, and the cooling problem of the sintered articles is solved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of phenol water, in particular to a method and system for treating and utilizing phenol water. Background technique [0002] In industrial production, a large amount of phenolic water will be produced when the gasifier is used to provide gas, which mainly comes from the washing water and phenolic condensed water in the process of cooling and purifying the gas. Phenol water contains phenol, ammonia, cyanide, sulfide, tar and other components. The amount of phenol-containing condensate depends on the gasification coal quality and the gasification process used. Phenol water has a strong pungent odor, is poisonous and harmful, and pollutes the environment. The use of a double-stage mixed gas generator can separate and recycle the tar and phenol water associated with gas production. Even if the phenol water is reused for the second time, the amount of phenol water will be greatly reduced t...
