Eliminating type coke oven afterheat recovery power generating system based on voltage stabilizing power supply circuit

Abstract

The invention discloses an eliminating type coke oven afterheat recovery power generating system based on a voltage stabilizing power supply circuit. The eliminating type coke oven afterheat recovery power generating system mainly consists of a coke oven top big pit and an oven top cylinder brick covering the top surface of the coke oven top big pit, wherein a perforated steel plate, a heat insulation plate layer and a perforated steel plate are sequentially arranged inside the coke oven top big pit from bottom to top, a heat insulation brick layer arranged between the perforated steel plate and the heat insulation plate layer is formed by filling heat-resistant sealing slurry in an inside gap part of the coke oven top big pit, a heat exchanger and an evaporator forming a sealed loop are arranged outside the coke oven top big pit, an afterheat power generating system is also arranged on the evaporator, an afterheat control circuit is arranged in the afterheat power generating system, a static electricity eliminating circuit, an overcurrent protection circuit, a control type power supply circuit, a voltage stabilizing power supply circuit and a control type output circuit are arranged in the afterheat control circuit, and the overcurrent protection circuit, the control type power supply circuit, the voltage stabilizing power supply circuit and the control type output circuit are in sequential connection.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to an elimination type coke oven waste heat recovery power generation system based on a stabilized voltage power supply circuit. Background technique [0002] Coke oven, also known as coke oven, is a furnace made of refractory bricks and refractory blocks. It is the main thermal equipment used to make coal to produce coke, while modern coke oven refers to the main purpose of producing metallurgical coke. 1. A horizontal chamber coke oven capable of recycling coking chemical products, which is mainly composed of a furnace body and auxiliary equipment. [0003] Due to the characteristics of coke oven production, the surface temperature of the existing coke oven is relatively high, and the temperature of the top surface of the coke oven is about 90°C, which accounts for more than 8% of the total heat consumption of the coke oven. At present, all international and domestic coke o...
