AI Technical Summary

Technical Problem

The waste heat recovery efficiency of high-temperature exhaust gas in the existing white carbon black production is low, resulting in the failure to effectively absorb heat, and the water temperature in the water tank is uneven, which has the problem of uneven heating.

Method used

A waste heat recovery device for the production of white carbon black is designed, including a heat exchange box, a heat exchange chamber, an intake pipe, an outlet pipe, a curved and folded heat exchange pipe and a circulation mechanism. The flow of high-temperature exhaust gas is controlled by the air conductor mechanism, and the rotation of the rotating connecting block is driven by the transmission mechanism, so that the heat exchange pipe rotates in the heat exchange chamber, increases the contact area with cold water, and improves the water flowability through the circulation mechanism.

Benefits of technology

It effectively improves the heat absorption of high-temperature exhaust gas, realizes uniform heating of cold water, solves the problem of uneven water temperature in the water tank, and improves the efficiency of waste heat recovery.

Abstract

The invention relates to the technical field of white carbon black production, and discloses a white carbon black production waste heat recovery device which comprises a base and a heat exchange box installed on the base. A heat exchange cavity is formed in the heat exchange box, a water inlet pipe and a water outlet pipe which communicate with the heat exchange cavity are installed on one side of the heat exchange box, and an air inlet pipe and an air outlet pipe which extend into the heat exchange cavity are installed at the two ends of the heat exchange box correspondingly. The bent and folded heat exchange pipe can rotate through the flow guide mechanism and the transmission mechanism, cold water in the heat exchange cavity can be uniformly heated in cooperation with the circulation mechanism, and high-temperature tail gas can stay in the gas inlet pipe, the heat exchange pipe and the gas outlet pipe for a certain time through the control mechanism and the gas guide mechanism; therefore, the high-temperature tail gas can have sufficient contact time with cold water in the heat exchange cavity through the heat exchange pipe, heat in the high-temperature tail gas can be effectively absorbed by the cold water conveniently, and the emission temperature of the high-temperature tail gas can be controlled.
