Abstract

The invention discloses a wet protection type coke oven after heat power generating system based on a stabilization power supply circuit. The wet protection type coke oven after heat power generating system based on the stabilization power supply circuit mainly consists of a coke oven top hollow place and oven top cylinder bricks covering the surface of the top thereof. A porous steel plate, a heat insulation plate layer and another porous steel plate are sequentially arranged inside the coke over top hollow place from top to bottom. Heat preservation brick layers are arranged among the porous steel plates and the heat insulation plate layer; and a heat-resisting sealing pulp is filled inside the seam of the coke oven top hollow place. A heat exchanger and an evaporator forming an enclosed loop are arranged outside the coke oven top hollow place. The evaporator is further provided with an after heat power generating system. An after heat control circuit is arranged inside the after heat power generating system. The after heat control circuit is provided with a thermal induction automatic switching circuit, and a controlled power supply circuit, a stabilization power supply circuit as well as a controlled output circuit that are sequentially connected with one another.

Description

technical field

[0001] The invention relates to a waste heat power generation system, in particular to a humidity protection type coke oven waste heat power generation system based on a stabilized voltage 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 ove...

Examples

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...
