Novel hard carbon black reaction furnace

Abstract

The invention discloses a novel hard carbon black reaction furnace. The carbon black reaction furnace is formed by an air distributor, a gas distributor, a combustion section and a throat pipe straight section through axial coaxial sealing connection. A raw oil gun is axially and horizontally arranged in the central position of a panel of the carbon black reaction furnace; a muzzle of the raw oilgun extends into the front 200 to 300 mm part of the throat pipe straight section. The novel hard carbon black reaction furnace disclosed by the invention has the following technical effects: different types of carbon black can be produced without changing a reaction furnace body; by using the reaction furnace to produce carbon black, the requirements on the quality on raw oil can be reduced and the production cost of enterprises is reduced; a product of the carbon black has the advantages of high color strength, high compression oil absorption value and capability of meeting the quality requirements of all-steel radial tires; in addition, preheated air, gas and raw oil has no damages on the reaction furnace body in the combustion reaction process, so that the service life of the reactionfurnace is prolonged.

Description

technical field [0001] The invention relates to a carbon black reaction furnace, in particular to a novel hard carbon black reaction furnace. Background technique [0002] High structure carbon black endows filled vulcanizate with higher modulus stress and better wear resistance. As one of the three basic properties of carbon black, structure has always been an important control index in the production process. However, for a long time, the control of this indicator by various manufacturers mainly depends on the type of raw material oil and its proportion. Although this can meet the control requirements, it limits the flexibility of operation, and oil products with high aroma factors often The price is expensive, which is not conducive to the improvement of economic benefits. Therefore, it is undoubtedly necessary to find an effective means of controlling and adjusting the structure from the process to achieve the purpose of stabilizing product quality and reducing costs. ...

AI Technical Summary

Problems solved by technology

[0004] The invention relates to a new type of hard carbon black reaction furnace, which solves the problems of single carbon black produced by the existing reaction furnace, insufficient coloring strength, difficult control of the reaction temperature, and low output ratio. Carbon black requires the use of different reaction furnaces, which reduces the need to stop production and replace the entire production device when the furnace type is replaced, which affects the company's benefits. At the same time, it also changes that only "good oil" can be used to produce high-quality carbon black. , increase production costs, affect the competitiveness of enterprise products and other issues
