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 thermal protection type coke oven waste heat power generation system based on a power source adjustment circuit. The system is mainly composed of coke oven top large pits and oven top clinker bricks covering the surfaces of the tops of the coke oven top large pits, a pored steel plate, a thermal insulation board layer and a pored steel plate are arranged inside each coke oven top large pit in sequence from bottom to top, a thermal insulation brick layer is arranged between each pored steel plate and the corresponding thermal insulation board layer, gaps, inside the corresponding coke oven top large pit, of each thermal insulation brick layer are filled with heatproof sealing slurry in a poured mode, heat exchangers and an evaporator forming a closed loop are arranged outside the coke oven top large pits, a waste heat power generation system body is further arranged on the evaporator, a waste heat control circuit is arranged in the waste heat power generation system body, and an over-temperature protection circuit and a control type power source circuit, the power source adjustment circuit and a control type output circuit which are connected in sequence 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 thermally protected coke oven waste heat 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 hav...
