Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in figures 1-4, oven top of coke oven hollow place 1 of the present invention is piled up by fragment of brick or cement etc. and is formed, the cross section of its internal cavities is inverted trapezoidal shape, namely the bottom width of this oven top of coke oven hollow place 1 is less than its top width, the bottom of oven top of coke oven hollow place 1 is then the base 13 of oven top of coke oven hollow place 1, is also provided with special heat exchanger system and atresia steel plate 7 in this oven top of coke oven hollow place 1 inside.
Effectively can be incubated in order to ensure the present invention, stop defects such as smoldering, burn with anger, therefore be provided with porose steel plate 3, thermal baffle layer 4, porose steel plate 3 and furnace roof clinker tile 2 from bottom to up successively at the cavity inside of this oven top of coke oven hollow place 1.Due to when laying, between not only described porose steel plate 3 and thermal baffle layer 4, between thermal baffle layer 4 and porose steel plate 3, between porose steel plate 3 and furnace roof clinker tile 2, there is gap, and also have gap between these porose steel plate 3 and inwalls of thermal baffle layer 4 and oven top of coke oven hollow place 1, therefore, the present invention must fill with at these gap places and fill out temperature resistant encapsulation slurry 5, to guarantee that oven top of coke oven hollow place 1 inside is the entirety of a sealing.
According to actual demand during construction, the present invention also in the inside of oven top of coke oven hollow place 1, can also lay one layer of heat preservation brick layer 6 between porose steel plate 3 and thermal baffle layer 4.Correspondingly, its gap each other also needs filling to fill out temperature resistant encapsulation slurry 5.
The KP1 that temperature resistant encapsulation slurry 5 of the present invention is preferentially 5% ~ 10% by refractory wass and concentration mixes, described thermal baffle layer 4 is that the thermal insulation board monoblock being 100mm by two layers of thickness is built by laying bricks or stones and formed, or sting block to form, the aperture of described porose steel plate 3 is then preferentially made into 60mm.
The present invention is provided with heat exchanger system, atresia steel plate 7, thermal baffle layer 4, porose steel plate 3 and furnace roof clinker tile 2 from bottom to up successively in the inside of oven top of coke oven hollow place 1, and the plane of this furnace roof clinker tile 2 will with the plane of oven top of coke oven hollow place 1 in same level.
Described heat exchanger system is then made up of the heat exchanger 8 between the base 13 being arranged on atresia steel plate 7 and oven top of coke oven hollow place 1 and the evaporator 9 that is arranged on oven top of coke oven hollow place 1 outside.Heat exchanger 8 of the present invention is different with traditional heat exchanger structure, and it is the pedestal 10 made by cement, and the heat exchange heat pipe 11 of the inside being arranged on this pedestal 10 is formed.
In order to ensure result of use, this heat exchange heat pipe 11 is that serpentine is arranged in the inside of pedestal 10, or arranges twist, and this heat exchange heat pipe 11 is only provided with one deck in the inside of pedestal 10.The two ends of this heat exchange heat pipe 11 then respectively introduction pipe be connected with downcomer with the riser of evaporator 9, namely make between evaporator 9 and heat exchanger 8, to form a circulation circuit sealed.Meanwhile, this heat exchange heat pipe 11 is also provided with fin 12, to guarantee further to improve its heat transfer rate.
In like manner, the present embodiment not only between pedestal 10 and base 13, fill with between atresia steel plate 7 and pedestal 10, between thermal baffle layer 4 and atresia steel plate 7, between porose steel plate 3 and thermal baffle layer 4 and between furnace roof clinker tile 2 and porose steel plate 3 and be filled with temperature resistant encapsulation slurry 5, and at pedestal 10, atresia steel plate 7, thermal baffle layer 4, also fill with between porose steel plate 3 and the inwall of oven top of coke oven hollow place 1 and be filled with temperature resistant encapsulation slurry 5, namely make the inside of whole oven top of coke oven hollow place 1 become as a whole by this temperature resistant encapsulation slurry 5.
Because coke oven is a large-scale body of heater, the quantity of the oven top of coke oven hollow place 1 arranged at its top can reach tens, even up to a hundred, but when constructing, the inside of each oven top of coke oven hollow place 1 only arranges a heat exchanger 8, and an evaporator 9 is also only set in the outside of oven top of coke oven hollow place 1, all heat exchangers 8 are all connected with this evaporator 9 by pipeline.
In order to ensure result of use, the closed circuit that this heat exchanger 8 and evaporator 9 are formed needs to be in vacuum state, namely the pipe interior that described heat exchange heat pipe 11 is connected with evaporator 9 is vacuum state, and is also provided with in its pipeline closed for participating in the circulation fluid circulated.The volume of this circulation fluid can regulate according to the difference in summer and winter, thus guarantees its heat exchange efficiency.
