Description
Technical Field
[0001] The utility model relates to the field of chemical industry, in particular to solid-gas separation equipment for carbon black production. Background Art
[0002] The main reason for solid-gas separation in the carbon black production process is that a large amount of gas, such as carbon monoxide, is produced during the production of carbon black, accompanied by solid particles. The mixture of these gases and solid particles needs to be effectively separated to ensure the continuity of the production process and the quality of the carbon black product. Specifically, the solid-gas separation process helps to remove impurities mixed in the carbon black and improve the purity of the product.
[0003] In the prior art, solid-gas separation during carbon black production is usually performed by sequentially passing the solid-gas mixture into multiple water tanks filled with separation liquid to ensure the separation quality. The separation equipment of multiple water tanks occupies a large area, and the evolution efficiency of a single separation tank is low. Utility Model Content

[0006] Furthermore, the separation barrel is in the shape of a round barrel with a support leg at the bottom, a discharge port is arranged on one side of the bottom of the separation barrel, a plug is embedded in the discharge port, an outer card platform is arranged on the top of the separation barrel, and a barrel cover card is embedded on the outer card platform.
[0007] Furthermore, the barrel cover is in a conical cover shape, and an inner snap-in is provided on the inner wall of the bottom of the barrel cover. The inner snap-in is movably embedded in the outer snap-in platform. An air inlet pipe is provided in the center of the upper surface of the barrel cover, an air outlet pipe is provided on the left side of the air inlet pipe, and handles are provided on both sides of the upper surface of the barrel cover. An exhaust cavity connected to the air inlet pipe is provided in the center of the inner wall of the barrel cover, the exhaust fan is fixedly provided in the exhaust cavity, and the reflux air distribution pipe is fixedly embedded below the exhaust cavity.
[0008] Furthermore, the top of the reflux air distribution pipe is a T-shaped conical tube-shaped air inlet chamber, below the air inlet chamber is an acceleration chamber with a slender diameter, below the acceleration chamber is an air distribution chamber with cones on the upper and lower sides and a barrel-shaped middle section, a through air outlet is arranged at the center of the cone below the air distribution chamber, a plurality of air distribution branch pipes distributed in a circular array are arranged on the side of the cone below the air distribution chamber, a plurality of hollow triangular cone-shaped reflux chambers distributed in a circular array are arranged on the side of the cone above the air distribution chamber, and the upper surface of the reflux chamber is provided with dense air inlet holes that penetrate into the internal cavity.
[0009] The beneficial effects of the utility model are as follows: the air inlet pipe of the barrel cover is connected with the external air pipeline, and an exhaust fan is arranged in the barrel cover.

[0020] In a specific embodiment, after the separation barrel 1 completes the separation, the separation liquid in the separation barrel 1 needs to be replaced and cleaned, the plug 3 is opened, the separation liquid is poured out from the discharge port 12, and the solid materials deposited at the bottom of the separation barrel 1 are manually rinsed and collected.
[0021] Preferably, the barrel cover 2 is in a conical cover shape, and an inner snap-in 24 is provided on the inner wall of the bottom of the barrel cover 2. The inner snap-in 24 is movably embedded in the outer snap-in platform 11. An air inlet pipe 21 is provided at the center of the upper surface of the barrel cover 2, and an air outlet pipe 22 is provided on the left side of the air inlet pipe 21. Handles 23 are provided on both sides of the upper surface of the barrel cover 2.

The exhaust fan 4 is fixedly arranged in the exhaust cavity 25, and the reflux air distribution pipe 5 is fixedly embedded below the exhaust cavity 25.
[0022] Preferably, the top of the reflux air distribution pipe 5 is a T-shaped conical tube-shaped air inlet chamber 51, below the air inlet chamber 51 is an acceleration chamber 52 with a slender diameter, below the acceleration chamber 52 is an air distribution chamber 53 with conical surfaces on the upper and lower sides and a barrel-shaped middle section, a through air outlet is arranged at the center of the cone surface below the air distribution chamber 53, a plurality of air distribution branch pipes 54 distributed in a circular array are arranged on the side surface of the cone surface below the air distribution chamber 53, a plurality of hollow triangular cone-shaped reflux chambers 55 distributed in a circular array are arranged on the side surface of the cone surface above the air distribution chamber 53, and the upper surface of the reflux chamber 55 is provided with densely distributed air inlet holes that penetrate into the internal cavity.
[0023] In a specific embodiment, below the air inlet chamber 51 is an acceleration chamber 52 with a slender diameter, and below the acceleration chamber 52 is an air dividing chamber 53 with conical surfaces on the upper and lower sides and a barrel-shaped middle section. When high-speed gas enters the acceleration chamber 52 from the air inlet chamber 51, the gas flow cross-section shrinks, the gas flow velocity in the acceleration chamber 52 accelerates, and the conical surface above the air dividing chamber 53 forms a nozzle effect on the accelerated gas, further increasing the flow velocity of the gas in the conical area above the air dividing chamber 53, so that a static pressure difference is formed between the reflux chamber 55 and the conical area above the air dividing chamber 53, and the reflux chamber 55 generates negative pressure suction.
[0024] In a specific embodiment, the air inlet pipe 21 of the barrel cover 2 is connected to the external air pipeline, and an exhaust fan 4 is arranged in the barrel cover 2.

The reflux chamber 55 generates negative pressure under the action of the pressure difference to suck the gas in the separation barrel 1 back to the air distribution chamber 53 for secondary introduction into the separation liquid for separation, thereby realizing multiple reflux and diversion of the solid-gas mixed flue gas in the separation barrel 1.
