Co-production processing method and equipment for carbon black and oil

Abstract

The present invention discloses a co-production processing method and equipment for carbon black and oil. The co-production processing method and equipment are characterized in that: an online tubular furnace is arranged between a carbon black reaction furnace and an air preheater; the online tubular furnace is divided into, from the bottom to top in turn, a radiation section, an overheating section and a convection section; a water-containing oil heating temperature adjusting system, a superheated steam temperature adjusting system, a water-free oil heating temperature adjusting system, a temperature alarm interlock system and other systems are also arranged; the physical heat of high-temperature carbon black flue gas is used as a heat source for heating raw oil, so that the water-containing oil and water-free oil are heated to the required temperatures; saturated steam is superheated to a specified temperature, thus meeting the feed requirements of an oil processing unit; and simultaneously the oil-containing water discharged from the top of a first-stage evaporator of the oil processing unit can be directly mixed with chilling water of a carbon black device, thereby solving thedifficulty of oil-containing wastewater treatment, effectively reducing the addition amount of the chilling water, decreasing the amount of exhaust gases, increasing the chemical heat value of the exhaust gases, reducing energy consumption in exhaust gas transport, reducing the requirement capacity of processing equipment and simultaneously achieving the security operation.

Description

technical field [0001] The invention relates to a carbon black and oil processing co-production method and equipment. Background technique [0002] At present, many domestic carbon black enterprises are affiliated enterprises of coking plants or coal tar processing enterprises, or have the ability to process coal tar themselves, and some carbon black enterprises are affiliated enterprises of tire or tire sales enterprises. According to incomplete statistics, at the end of 2009, the carbon black production capacity of such carbon black enterprises combined with upstream and downstream enterprises had reached 1.695 million tons, accounting for 39% of the total carbon black production capacity in the country, and continued to develop rapidly. [0003] The simple material co-production of carbon black production and coal tar processing can reduce transportation costs and procurement costs, and improve economic benefits to a certain extent. [0004] According to the requirements...

AI Technical Summary

Problems solved by technology

This cooling method not only consumes water resources, but also makes the water content in the flue gas reach about 45% (volume), reduces the chemical calorific value of the exhaust gas, makes the subsequent application of the exhaust gas more difficult, and increases the flow rate of the exhaust gas at the same time. The collection and tail gas transportation of the carbon black device increases equipment investment and power consumption
