Ring cooler feed hopper cooling air heat recycling system

By using the cooling air hot circulation system of the ring cooler feed hopper, ambient temperature air is introduced into the ring cooler feed hopper for cooling, and high temperature hot air is introduced into the main burner for combustion. This solves the energy waste problem of direct exhaust of cooling air from the ring cooler feed hopper, and achieves efficient energy utilization and improved combustion efficiency.

AI Technical Summary

Technical Problem

In existing technologies, the cooling air from the feed hopper of the ring cooler is directly discharged, resulting in energy waste and failing to effectively utilize the high-temperature hot air.

Method used

Design a cooling air hot circulation system for the feed hopper of an annular cooler. Normal temperature air is introduced into the feed hopper for cooling through cooling pipes and cooling fans, and the cooled high temperature hot air is introduced into the main burner for combustion. The combustion fan is eliminated, and a Roots blower and a temperature sensor are used for flow regulation.

Benefits of technology

It enables the recycling of cooling gas, improves energy efficiency, reduces gas emissions, lowers production costs and air pollution, and ensures combustion efficiency and equipment stability.

Abstract

The application provides a cooling air heat circulation system of a ring cooler feeding hopper, which comprises a cooling pipeline, a ring cooler feeding hopper, a hot air pipeline and a main burner, the outlet end of the cooling pipeline is communicated with the ring cooler feeding hopper, a cooling fan is arranged on the cooling pipeline to guide the cooling gas into the ring cooler feeding hopper through the cooling pipeline, and the hot air pipeline is communicated with the ring cooler feeding hopper and the main burner respectively to guide the gas heated by the ring cooler feeding hopper into the main burner. By arranging the hot air pipeline, the high-temperature hot air cooled by the ring cooler feeding hopper can be introduced into the main burner to participate in combustion, the energy waste caused by the direct discharge of the high-temperature hot air is avoided, and the energy utilization efficiency is improved. By using the high-temperature hot air as the combustion-supporting air of the main burner, the temperature of the high-temperature hot air is higher than that of the normal-temperature combustion-supporting air used in the prior art, the combustion can be provided with more favorable conditions, the fuel combustion is more sufficient, the fuel consumption of the main burner is reduced, and the energy cost in the production process is reduced.
