Embodiment 1

[0027] Such as figure 1 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.

[0028] 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, between the perforated steel plate 3 and the kiln brick 2, And there are also gaps between these perforated steel plates 3 an...

Embodiment 2

[0032] Compared with the implementation examples, this embodiment differs in that a special heat exchanger system and a non-porous steel plate 7 are also provided inside the large pit 1 on the top of the coke oven.

[0033] Such as figure 2 As shown, the present invention is sequentially provided with a heat exchanger system, a non-porous steel plate 7, a heat insulation plate layer 4, a perforated steel plate 3 and a furnace top clinker brick 2 from bottom to top inside the coke oven top pit 1, and the The plane of furnace top clinker brick 2 will be on the same level as the plane of coke oven top pit 1.

[0034] The heat exchanger system is composed of a heat exchanger 8 arranged between the non-porous steel plate 7 and the base 13 of the coke oven top pit 1 and an evaporator 9 arranged outside the coke oven top pit 1 . The heat exchanger 8 of the present invention is different from the traditional heat exchanger structure. It is made of a base 10 made of cement and a heat...

Abstract

The invention discloses a coke oven top waste heat reclaiming system, which mainly consists of a coke oven top large pit (1) and an oven top quarry tile (2) covering the surface of the top of the large pit. The system is characterized in that a poriferous steel plate (3), a thermal baffle layer (4) and a poriferous steel plate (3) are sequentially arranged from bottom to top in the coke oven top large pit (1), and inner gaps of the coke oven top large pit (1) are filled with heat-resisting sealing slurry (5). According to the invention, through the measures that poriferous steel plates and the thermal baffle layer are arranged in the coke oven top large pit (1), the gaps are filled with the heat-resisting sealing slurry and the like, the temperature of the coke oven top surface can be effectively reduced, the heat preservation effect is very obvious, the energy-saving effect is very ideal, and the energy-saving rate can reach 0.4KW/m2.

Description

technical field [0001] The invention relates to a waste heat recovery device, in particular to a coke oven top waste heat recovery system. 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 following defects: First, there is no suitable recovery technology fo...
