Method for preparing sewage purification treatment material and device

Abstract

The invention relates to a preparation method of a sewage purification treatment material and a device thereof. The method comprises the steps of feeding powdered coke with small particle size into the device, and heating. The device comprises a roller positioned inside a heating chamber; one end of the roller is connected with a discharge pipe via a conical end; the other end of the roller is connected with a feed pipe; a plurality of rows of material turning over plates and material guide plates are fixed on the inner wall of the roller, each row of the material turning over plates and material guide plates are composed of a plurality of material turning over plates and a plurality of material guide plates that are alternately installed, and expansion gaps are arranged among the material turning over plates and material guide plates in the same row; spaces are left between every two rows of the turning over plates and material guide plates; each material guide plate is a triangular component composed of a flat surface and an inclined surface, the flat surface is arranged flush with the material turning over plates, and the tip ends of the material guide plates face the discharge pipe; a space is left between the middle part of the each material turning over plate and the inner wall of the roller; the discharge pipe is hermetically connected with a discharge chamber, and a vapor inlet port is arranged on the discharge chamber; the feed pipe is hermetically connected with a gas collection chamber; and a driving device is connected with the external part of the discharge pipe to drive the roller to rotate.

Description

technical field [0001] The invention belongs to a material processing method, and in particular relates to a method of using gas produced in the production process of a coking enterprise as a heat source to make sewage purification treatment materials from the waste in the production process of the coking enterprise-small coke powder with a particle size of ≤5mm method. [0002] The invention also relates to a device for carrying out the method described above. Background technique [0003] During the production process of coking enterprises, many small coke particles and powder mixtures with a particle size of ≤5mm are produced. At present, these small particle size mixtures cannot be effectively utilized and become wastes in the production process of coking enterprises. [0004] On the other hand, in the process of coking enterprises, while producing coke and tar products, coke oven gas is also produced, which is a by-product of the coking industry. Many small and mediu...

Problems solved by technology

The cost of activated coke and activated carbon is very high. When used to treat wastewater and sewage, enterprises cannot afford the cost of wastewater and sewage treatment

[0006] The known equipment or devices used to prepare activated carbon and activated coke from coke require the particle size of the raw material to be greater than 5mm, especially powder below 2mm. Can block the passage of water vapor, can't activate; 2) in the known rotary kiln with huge volume, because the particle diameter of roasted product is too small, can discharge into the atmosphere together with exhaust gas after combustion, not only can't recycle, but also increased air pollution

[0007] Due to the above reasons, there has been no report on the preparation of activated coke by using a mixture of small coke particles and powder with a particle size of ≤5mm as a raw material.
