Thermal protection type coke oven waste heat recovery power generation system based on power source voltage adjustment circuit

Abstract

The invention discloses a thermal protection type coke oven waste heat power generation system based on a power source voltage 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 a thermal inductance automatic switching circuit and a control type power source circuit, the power source voltage 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 heat-sensing coke oven waste heat power generation system based on a power rectifying 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 followin...
