Description

Technical Field

[0001] The utility model relates to the technical field of carbon black reaction furnaces, in particular to an improved throat pipe used in carbon black reaction furnaces. Background Art

[0002] As a reinforcing agent for rubber products, the demand for carbon black is increasing. The carbon black industry is a chemical industry with high energy consumption. These raw materials can also be used as industrial raw materials and are energy sources themselves. Therefore, energy conservation and consumption reduction in carbon black production has great potential. Energy conservation is also very important to the carbon black industry.

[0003] Carbon black raw oil is sprayed into the reactor throat at multiple points, with nozzles spraying at 30°, 45°, and 60° angles, mixed with high-temperature and high-speed flue gas from the reactor combustion chamber, and cracked to produce carbon black. However, since the angle of the preset oil gun of the throat is fixed, when it is necessary to produce carbon black products of different qualities or performances, the entire throat needs to be replaced, which is time-consuming and reduces production efficiency. At present, multiple carbon black reactors can be connected in parallel after the reactor or after the air preheater, and some are connected in parallel before entering the main bag filter. In order to facilitate the adjustment of carbon black quality, this not only increases the equipment footprint, but also increases the investment in the device, reducing economic benefits. Whether it is to increase the size of the carbon black reactor or adopt the production process of parallel carbon black reactors, the structure of the carbon black reactor has always been a single throat structure with one reactor and one throat. Utility Model Content

[0004] In order to solve the above problems, the utility model designs an improved throat pipe for a carbon black reaction furnace.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] An improved throat for a carbon black reactor comprises a throat, a shell is provided on the outer wall of the throat, a through hole is formed through the outer wall of the throat, a base is provided on the rear side wall of the shell, an oil gun is plugged into the top wall of the base, front and rear inner walls of the shell are rotatably connected to a round rod through a bearing, a cylinder is connected to the outer wall of the round rod by interference fit, a nozzle is provided at the bottom end of the cylinder, and the nozzle extends into the throat through the through hole, a motor is detachably provided on the front side wall of the shell, and the output end of the motor is fixedly connected to the front end of the round rod through a coupling.

[0007] Furthermore, the shell is communicated with the inner cavity of the throat through a through hole.

[0008] Furthermore, the oil gun, the base, the round rod, the cylinder and the nozzle are connected.

[0009] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the housing via a bearing seat, and the inner ring of the bearing is connected to the outer wall of the round rod by interference fit.

[0010] The beneficial effects of the utility model are:

[0011] Through multi-angle automatic adjustment, the oil pipe nozzle can distribute the raw oil more evenly, ensuring that there is an appropriate amount of raw material supply in each area of ​​the reactor, which can promote the uniformity of the combustion and cracking process and improve the quality of carbon black;

[0012] The multi-angle nozzle can better contact with the high-temperature gas, so that the crude oil can react more fully. At the same time, by optimizing the nozzle angle, the atomization degree of the crude oil can be improved, which is beneficial to the cracking of the crude oil and reduces the distribution range of carbon black particles, thereby improving the coloring strength of carbon black.

[0013] The multi-angle automatic adjustment function allows the oil pipe nozzle in the throat to be flexibly adjusted to meet the needs of producing carbon black products of different qualities or performances. This can avoid the operation of replacing the entire throat, saving time and cost and improving production efficiency;

[0014] By precisely controlling the distribution of the crude oil in the reactor and the reaction conditions, the performance of the carbon black product can be finely adjusted, which helps to improve the quality of carbon black and meet the market demand for high-quality carbon black.
