Description

Technical Field

[0001] The present invention relates to the technical field of dispersion devices, and specifically to a device for improving the dispersion of carbon black in carbon black flue gas and a method for using the same. Background Art

[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is carbon, and it contains small amounts of elements such as oxygen, hydrogen and sulfur. Currently, carbon black is generally prepared by the contact method, oil furnace method and thermal cracking method. In the production process of oil furnace carbon black, the carbon black formation reaction is completed in the reactor.

[0003] First, the fuel oil enters the fuel oil gun, is atomized by compressed air and then sprayed into the combustion section of the reactor to mix with the preheated high-temperature air for full combustion, generating high temperature. The high-temperature turbulent airflow enters the reactor tangentially, forming a high-speed rotating airflow in the carbon black reactor, and encounters the fully atomized and axially injected raw oil in the throat section of the reactor. The atomized raw oil droplets are cracked at high temperature to form carbon black aggregate powder. The powdered carbon black is wrapped in the high-temperature flue gas flow and continues to flow. After encountering the axially injected quenching water at the primary quenching position of the reactor, the cracking reaction is quickly terminated, ending the entire cracking and combustion reaction process. Then, the temperature needs to be further reduced at the secondary quenching position at the rear of the reactor to meet the temperature requirements of the rear equipment.

[0004] Normally, the secondary rapid cooling of carbon black is carried out by using a Venturi tube for cooling. Several water gun nozzles are provided at the straight section of the Venturi tube, and the water gun nozzles are connected to the water inlet pipe. Rapid cooling water is sprayed into the Venturi tube to cool down the high-temperature flue gas of carbon black, and the high-temperature flue gas containing powdered carbon black rises and enters the next bag filter collection process. In the process of secondary rapid cooling, carbon black scaling and wall adhesion are easily formed due to the uneven injection of rapid cooling water, and the powdered carbon black in the carbon black flue gas is unevenly distributed. When entering the collection bag filter, some filter bags have less carbon black, while others have too much carbon black, or the filter bag load is too large, resulting in abnormal parking accidents. Summary of the invention

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In the present invention, the static mixing baffle at the outlet can evenly stir and divide the high-temperature flue gas containing carbon black when the flue gas is discharged, thereby avoiding the uneven concentration of powdered carbon black and reducing the carbon black hanging on the pipe wall. This solves the problem that in the process of secondary rapid cooling of the existing carbon black flue gas, carbon black scaling and wall hanging are easily formed due to the uneven injection of rapid cooling water, and the uneven distribution of powdered carbon black in the carbon black flue gas.

[0030] 2. In the present invention, the flue gas containing powdered carbon black is stirred and mixed and divided at the same time through the synchronous relative rotation of two static mixing baffles, which facilitates the subsequent uniform distribution of carbon black. The two static mixing baffles are designed to be separately detachable, which facilitates the separation, cleaning, maintenance or replacement of the static mixing baffles, making the dispersion device more convenient to use.

[0031] 3. In the present invention, the scraper rod is driven to rotate simultaneously by the static mixing baffle, so that the inner wall of the venturi tube can be cleaned, and the smoke is prevented from scaling or hanging on the inner wall of the venturi tube during the cooling process, thereby ensuring the internal space of the venturi tube and further improving the convenience of maintenance of the venturi tube during use.
