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 protection-type coke oven waste heat recovery and power generation system based on a power adjustment circuit. The protection-type coke oven waste heat recovery and power generation system mainly comprises a coke oven top big hole and oven top clinker tiles covering the top surface of the big hole; the coke oven top big hole is internally provided with a porous steel plate, a heat insulation plate layer and a porous steel plate in sequence from bottom to top; a heat preservation brick layer is arranged between each porous steel plate and the heat preservation plate layer and is formed by pouring heat-resistant sealing slurry in internal slots of the coke oven top big hole; a heat exchanger and an evaporator which form a closed loop are arranged outside the coke oven top big hole; a waste heat power generation system is also arranged on the evaporator; a waste heat control circuit is arranged in the waste heat power generation system; an overcurrent protection circuit, a control type power circuit, the power adjustment circuit and a control type output circuit which are sequentially connected are arranged in the waste heat control circuit.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to a protection type coke oven waste heat recovery power generation system based on a power supply adjustment 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 mainl...
