Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the traditional output, cooling and separation of waste tire pyrolysis residues, which mostly adopt single spiral equipment with partition wall heat exchange, which makes it extremely difficult for large-scale pyrolysis residues to be extruded by a single spiral blade. Forming a dense material seal, it is impossible to realize the two-phase isolation and blocking output of waste tire pyrolysis residue output and pyrolysis gas phase output, as well as automatic and continuous treatment process and other technical problems, and provides a water method for waste tire pyrolysis residue Treatment process

Embodiment 1

[0060] Such as figure 1 As shown, the waste tire cracking residue sealing conveying device in this embodiment includes a sealed box 1, and the inside of the sealed box 1 is filled with water (not shown in the figure).

[0061] The front end of the sealed box 1 is provided with a pressing screw 2 as a feeding mechanism, and the pressing screw 2 includes an outer sleeve 21 and blades 22 . One end of the outer sleeve 21 is fixed on the top of the sealed box 1, and the other end is connected to the discharge port of the cracking reaction device (not shown in the figure). The pressing screw 2 is driven by an external electric motor. Because the weight of waste tire pyrolysis residue is relatively light, in order to effectively press it into the sealed box, the rotating speed of the pressing screw 2 is greater than or equal to 30 rpm.

[0062] A discharge mechanism is provided at the tail end of the sealed box 1, that is, a screw mechanism 4 with a jacketed hydrophobic opening st...

Embodiment 2

[0067] Such as figure 2 and 3 As shown, the water washing and sorting device for waste tire pyrolysis residue in this embodiment includes a sealed box 1, and a pressing screw 2 as a feeding mechanism is arranged on the top of the feeding side of the sealed box 1. The pressing screw 2 includes an outer sleeve 21 and blades 22 . One end of the outer sleeve 21 is fixed on the top of the sealed box 1, and the other end is connected to the discharge port of the cracking reaction device (not shown in the figure). A water isolation compartment 5 is provided on the discharge side of the sealed box 1 . The water isolation cabin 5 is adjacent to the sealing box 1, and the side plate on the discharge side of the sealing box 1 plays a role of separation, and isolates the water isolation cabin 5 from the upper part of the sealing box 1. A communication port 6 is provided at the bottom of the side plate 51 , so that the sealed box 1 and the water isolation compartment 5 become a communi...

Embodiment 3

[0074] Embodiments 1 and 2 jointly constitute the device used in the water treatment process of waste tire pyrolysis residues in Embodiment 3. For details, see Figure 4 , wherein the meanings indicated by the reference numerals are the same as those in Embodiments 1 and 2. The device is used to carry out the water treatment process of the present invention. The specific process is as follows:

[0075] The waste tire pyrolysis residue continuously output by the pyrolysis reaction equipment is conveyed to the feeding mechanism through the continuous conveying screw, pressurized by the speed of the pressing screw, and the waste tire pyrolysis residue is forced into more than 1L of water in the form of forced pressing. A sealed box, wherein the rotating speed of the pressing screw is 30 rpm. After the waste tire pyrolysis residue enters the airtight water tank full of water, it is cooled under the action of water. At this time, the stirring and propulsion mechanism under the si...

Abstract

The invention discloses a water treatment process of residues from pyrolyzed waste tire. The process comprises the following steps that the residues from pyrolyzed waste tire are input into a sealing box fully filled with water inside; under stirring propulsion of a stirring propulsion mechanism, remained coals in the residues from pyrolyzed waste tire are shifted to the tail end of the sealing box body for outputting; steel wires in the residues from pyrolyzed waste tire are shifted to the bottom of the sealing box for gathering, and are collected; a feeding mechanism performs an input operation, and is a pressing spiral; the stirring propulsion mechanism is a stirring propulsion spiral horizontally arranged; and the stirring propulsion spiral is a total spiral, an interrupted spiral or a rake tooth spiral. The process realizes two-phase effective isolation stop outputting of solid-phase outputting and splitting gas-phase outputting of residues from pyrolyzed waste tire, and realizes automatic continuous all-closed water treatment of the residues from pyrolyzed waste tire.

Description

technical field [0001] The invention relates to a water treatment process for waste tire pyrolysis residue. Background technique [0002] With the continuous development of waste tire pyrolysis treatment process, its processing scale is becoming more and more productive, but the ensuing problems of waste tire pyrolysis residue output sealing and residual carbon steel wire separation still restrict the development of industrialized and standardized industries. [0003] Since the cracking reaction of waste tires produces hydrocarbon gases and solid residue products (the solid residue products are also called waste tire pyrolysis residues), the hydrocarbon gas temperature is as high as 400 ° C and is flammable and explosive when it leaks into the air. Therefore, when the waste tire pyrolysis residue is exported, it must be strictly sealed to prevent hydrocarbon gas from "escaping" to the external space when the solid residue is exported. Due to the presence of irregular steel ...
