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, betwee...

Abstract

The invention discloses a coke oven top waste heat recycling and electricity generation system based on an efficient drive power source circuit. The coke oven top waste heat recycling and electricity generation system is mainly composed of a large coke oven top pit and oven top quarry tiles covering the surface of the top of the pit. The large coke oven top pit is internally and sequentially provided with a porous steel plate, a heat insulation plate layer and the porous steel plate from bottom to top. A heat preservation tile layer arranged between the porous steel plates and the heat insulation plate layer is formed by pouring heat-resisting sealing slurry into seams of the large coke oven top pit. A heat exchanger and an evaporator for forming a sealing loop are arranged outside the large coke oven top pit. The evaporator is further provided with a waste heat electricity generation system. The waste heat electricity generation system is internally provided with a waste heat control circuit. The waste heat control circuit is internally provided with a control type power circuit, the efficient drive power source circuit, and a control type output circuit which are sequentially connected.

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 high-efficiency drive power 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 have t...
