Embodiment

[0036] 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.

[0037] 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 warning type coke oven waste heat recovery power generation system based on a boosting power supply circuit. The warning type coke oven waste heat recovery power generation system based on the boosting power supply circuit is mainly composed of a big coke oven top pit, oven top clinker bricks which cover the top surface of the big coke oven top pit, a porous steel plate, an insulation board layer and a porous steel plate arranged in the big coke oven top pit in sequence from the bottom to top, an insulating brick layer arranged between the porous steel plate and insulation board layer, and heat-resistant sealing slurry filled in a gap in the big coke oven top pit, a heat exchanger and an evaporator which form a closed loop are arranged at the outside of the big coke oven top pit, the evaporator is further provided with a waste heat power generation system, a waste heat control circuit is arranged in the waste heat power generation system, and the waste heat control circuit is provided with an outage warning circuit, and an over-current protection circuit, a control type power circuit, the boosting power supply circuit and a control type output circuit connected in sequence.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to an alarm type coke oven waste heat recovery power generation system based on a boosted 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 have ...
