Embodiment 1

[0043] Such as Figure 5 As shown, the present embodiment provides a solid-liquid mixture processing method, comprising the following steps:

[0044] The step of transporting the solid-liquid mixture. In this step, the solid-liquid mixture is transported on a conveying device. The conveying device has two stages of conveying surfaces. The first stage of conveying surface is located above the side of the second stage of conveying surface. The first-level transmission surface 200 and the second-level transmission surface 300 are connected by a transition device 500, the height between the first-level transmission surface 200 and the second-level transmission surface 300 is greater than 100 cm, and the transmission device can mix solid-liquid Sludge is transported from the head end of the first-stage transmission surface to the tail end of the first-stage transmission surface, and then introduced to the second-stage transmission surface through the transition device 500, and tran...

Abstract

The invention relates to a solid-liquid mixture processing method including the steps of transportation of a solid-liquid mixture, squeezing dehydration of the solid-liquid mixture, and drying of the solid-liquid mixture; in the drying step, a drying device is used for drying the solid-liquid mixture after squeezing dehydration and comprises a second rotary shaft which is arranged in a cavity of a furnace body in a penetration manner; the second rotary shaft is provided with a ventilation cavity; the ventilation cavity is provided with a plurality of gas jet holes, and the gas jet direction of the gas jet holes does not coincide with and is not parallel to the stirring direction of a stirring shaft and the stirring direction of blades; when the material is dried, hot gas is introduced into the cavity of the furnace body through a first gas inlet, the second rotary shaft rotates to drive a stirring assembly on the second rotary shaft to continuously stir the material in the radial and axial directions of the second rotary shaft, so that the material can roll over in the furnace body in the axial and radial directions of the second rotary shaft, the material stirring time is increased, and the convection heat transfer area of the material with the hot gas is increased.

Description

technical field [0001] The invention relates to the technical field of solid-liquid mixture treatment, in particular to a solid-liquid mixture treatment method. Background technique [0002] Sludge is the product of the sewage treatment process, which contains a large amount of organic matter, heavy metals and molds, etc. If no follow-up treatment is added, it will cause serious pollution to the environment. Therefore, it is often necessary to concentrate and dehydrate the sludge, but after this treatment The moisture content of the final sludge is usually above 70%, and the sludge needs to be further dried. [0003] In the prior art, the drying system used for sludge drying is mostly structured as the drying system disclosed in the Chinese patent document CN201058838Y, including a furnace body, a feeder connected to the feed port of the furnace body, and an air outlet of the furnace body. Connected spray tower. Among them, the furnace body includes a transmission shaft ar...
