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 roof waste heat recovery power generation system based on a power supply adjusting circuit. The system is composed of a coke oven roof pit and roof quarry tiles covering the surface of the roof. A hole steel plate, a thermal insulation plate layer and a hole steel plate are arranged inside the coke oven roof pit from bottom to top in order. an insulation tile layer arranged between the hole steel plate and the thermal insulation plate layer is poured with heatproof sealing slurry at the internal seam of the coke oven roof pit. A heat exchanger and an evaporator forming an enclosed loop are arranged outside the coke oven roof pit. A waste heat power generation system is arranged on the evaporator. A waste heat control circuit is arranged in the waste heat power generation system. A control-type power supply circuit, a power supply adjusting circuit and a control-type output circuit are arranged in the waste heat control circuit and the control-type power supply circuit, the power supply adjusting circuit and the control-type output circuit are connected in order.

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 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 mainly have the f...
