Foundation protection structure of heat recovery coke oven

Abstract

The invention relates to a foundation protection structure of a heat recovery coke oven. The foundation protection structure comprises an oven bottom protection cross beam supporting plate, a foundation protection base, a heat dissipation assembly and reinforcing assemblies, wherein a plurality of groups of heat dissipation assemblies are arranged in each ventilation hole of the foundation protection base; multiple reinforcing assemblies are arranged, and each reinforcing assembly is composed of an installation channel, a supporting frame and a plurality of reinforcing columns; the installation channels penetrate through the foundation protection base, the supporting frames are arranged in the installation channels in a full-length mode, the supporting frames are each of a broken-line-shaped structure, and the reinforcing columns are vertically arranged between the inflection points of the tops of the supporting frames and the bottom faces of the installation channels. According to the invention, multiple sets of cooling fins are arranged in the ventilation holes, so a heat dissipation area is effectively increased, and ventilation cooling effect is enhanced; multiple rows of the reinforcing assemblies are arranged in the foundation protection base in the full-length mode, so the overall strength of the foundation protection base is effectively improved; and protection on the foundation of the heat recovery coke oven is enhanced, and the service life of the coke oven foundation is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of heat recovery coke ovens, in particular to a basic protection structure for heat recovery coke ovens. Background technique [0002] Heat recovery coke oven refers to a coke production device with micro-negative pressure operation in the coke oven carbonization chamber, mechanized tamping, coal charging, coke discharge, recovery and utilization of waste heat from coking combustion exhaust gas, mainly for the production of foundry coke. [0003] The bottom of the heat recovery coke oven body is fixedly connected to the furnace bottom protection beam support plate, and the bottom of the furnace bottom protection beam support plate is fixedly connected to the basic protection base. The base protection base is made of high-temperature resistant clay bricks. In order to prevent the base protection base from being damaged by thermal expansion during the long-term high-temperature production process of the heat r...

AI Technical Summary

Problems solved by technology

This device can prevent expansion and falling off at the bottom of the coke oven to a certain extent, but there are still the following deficiencies: 1. The reinforcement pillars are only set near the outer side of the coke oven foundation, and the reinforcement capacity is limited, and there is no overall reinforcement structure to enhance the coke oven foundation. Overall strength; 2. The heat dissipation area of ​​the ventilation holes is limited, and the heat cannot be quickly exported
