Embodiment

[0033] 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.

[0034] 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, betwee...

Abstract

The invention discloses a voltage stabilizing power supply circuit based elimination type coke oven waste heat power generation system. The voltage stabilizing power supply circuit based elimination type coke oven waste heat power generation system is mainly formed by a large hole and an oven top clinker brick, wherein the large hole is formed at the oven top of a coke oven and the oven top clinker brick covers the surface of the top of the large hole; a porose steel plate, a heat insulation plate layer and a porose steel plate are arranged inside the large hole from bottom to top in turn; an internal gap formed between the large hole and a heat insulation brick layer which is arranged between each porose steel plate and the heat insulation plate layer is filled with heatproof sealing paste; a heat exchanger and an evaporator which form a closed circuit are arranged outside the large hole; the evaporator is provided with a waste heat power generation system; a waste heat control circuit is arranged in the waste heat power generation system; a static elimination circuit, a control type power supply circuit, a voltage stabilizing power supply circuit and a control type output circuit are arranged in the waste heat control circuit, wherein the control type power supply circuit, the voltage stabilizing power supply circuit and the control type output circuit are connected in turn.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to an elimination type coke oven waste heat 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 ovens main...
