Embodiment

[0030] Such as Figure 1~4 As shown, the coke oven top pit 1 of the present invention is formed by stacking bricks or cement, etc., and the cross section of its internal cavity is in the shape of an inverted trapezoid, that is, the width of the bottom of the coke oven top pit 1 is smaller than that of the top. width, and the bottom of the coke oven top pit 1 is the base 13 of the coke oven top pit 1, and a special heat exchanger system and a non-porous steel plate 7 are also arranged inside the coke oven top pit 1.

[0031]In order to ensure that the present invention can effectively carry out heat preservation and eliminate defects such as smoke and fire, a perforated steel plate 3, a heat insulating plate layer 4, a Perforated steel plate 3 and furnace top clinker brick 2. Because when laying, not only there are gaps between the perforated steel plate 3 and the heat insulating plate layer 4, between the heat insulating plate layer 4 and the perforated steel plate 3, between...

Abstract

The invention discloses a coke oven top afterheat recovery power generating system based on a voltage stabilizing power supply circuit. The coke oven top 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, and a control type power supply circuit, a voltage stabilizing power supply circuit and a control type output circuit which are in sequential connection are arranged in the afterheat control circuit.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to a coke oven top waste heat recovery power generation system based on a voltage stabilized 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 ovens mainly ha...
