The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Embodiment 1
As shown in Figure 1; The coke oven furnace roof hollow place 1 of the utility model is piled up by fragment of brick or cement etc. and is formed; The cross section of its internal cavities is down trapezoidal shape, and promptly the bottom width of this coke oven furnace roof hollow place 1 is less than its top width, and the bottom of coke oven furnace roof hollow place 1 then is the base 13 of coke oven furnace roof hollow place 1.
Can effectively be incubated in order to ensure the utility model, therefore defective such as stop to smolder, burn with anger is provided with porose steel plate 3, thermal baffle layer 4, porose steel plate 3 and furnace roof clinker tile 2 at the cavity inside of this coke oven furnace roof hollow place 1 from bottom to up successively.Because when laying; Between not only described porose steel plate 3 and the thermal baffle layer 4, between thermal baffle layer 4 and the porose steel plate 3, have the slit between porose steel plate 3 and the furnace roof clinker tile 2; And also there is the slit between the inwall of these porose steel plates 3 and thermal baffle layer 4 and coke oven furnace roof hollow place 1; Therefore, the utility model must be irritated at these places, slit and filled out temperature resistant encapsulation slurry 5, to guarantee that coke oven furnace roof hollow place 1 inside is the integral body of a sealing.
Actual demand during according to construction, the utility model also can also be laid one deck insulating brick-layer 6 in the inside of coke oven furnace roof hollow place 1 between porose steel plate 3 and thermal baffle layer 4.Correspondingly, its slit each other also need be irritated and filled out temperature resistant encapsulation slurry 5.
The temperature resistant encapsulation slurry 5 of the utility model is that 5%～10% waterglass mixes by refractory wass and concentration preferentially; 4 of described thermal baffle layers are built by laying bricks or stones for the thermal insulation board monoblock that is 100mm by two layers of thickness and are formed; Perhaps sting block and form, the aperture of described porose steel plate 3 then preferentially is made into 60mm.
Embodiment 2
Present embodiment is compared with examples of implementation, and difference is also to be provided with special heat exchanger system and atresia steel plate 7 in this coke oven furnace roof hollow place 1 inside.
As shown in Figure 2; The utility model 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 coke oven furnace roof hollow place 1, and the plane of this furnace roof clinker tile 2 will with the plane of coke oven furnace roof hollow place 1 on same horizontal plane.
Described heat exchanger system is then by the heat exchanger 8 between the base 13 that is arranged on atresia steel plate 7 and coke oven furnace roof hollow place 1 and be arranged on the outside evaporimeter 9 of coke oven furnace roof hollow place 1 and form.The described heat exchanger 8 of the utility model is different with traditional heat exchanger structure, and it is the pedestal of being made by cement 10, and heat exchange heat pipe 11 formations that are arranged on the inside of this pedestal 10, and its structure is as shown in Figure 4.
In order to ensure result of use, this heat exchange heat pipe 11 is serpentine to be arranged in the inside of pedestal 10, or arranges twist, and this heat exchange heat pipe 11 only is 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 the tedge and the down-comer of evaporimeter 9, promptly make between evaporimeter 9 and the heat exchanger 8 closed circuit that forms a sealing.Simultaneously, on this heat exchange heat pipe 11, also be provided with fin 12, to guarantee further to improve its heat transfer rate.
In like manner; Present embodiment is not only between pedestal 10 and the base 13, between atresia steel plate 7 and the pedestal 10, between thermal baffle layer 4 and the atresia steel plate 7, between porose steel plate 3 and the thermal baffle layer 4 and irritate between furnace roof clinker tile 2 and the porose steel plate 3 and be filled with temperature resistant encapsulation slurry 5; And between the inwall of pedestal 10, atresia steel plate 7, thermal baffle layer 4, porose steel plate 3 and coke oven furnace roof hollow place 1, also irritate and be filled with temperature resistant encapsulation slurry 5, promptly make the inside of whole coke oven furnace roof hollow place 1 become as a whole through this temperature resistant encapsulation slurry 5.
Because coke oven is a large-scale body of heater; The quantity of the coke oven furnace roof hollow place 1 that is provided with at its top can reach tens, even up to a hundred, but when construction; The inside of each coke oven furnace roof hollow place 1 all only is provided with a heat exchanger 8; And an evaporimeter 9 also only is set in the outside of coke oven furnace roof hollow place 1, and all heat exchangers 8 all are connected with this evaporimeter 9 through pipeline, and its structure is as shown in Figure 3.
In order to ensure result of use; This heat exchanger 8 need be in vacuum state with evaporimeter 9 formed closed loops; Be that the pipe interior that described heat exchange heat pipe 11 is connected with evaporimeter 9 is a vacuum state, and in the pipeline of its sealing, also be provided with and be used to the circulation fluid of participating in circulating.The volume of this circulation fluid can be regulated according to the difference in summer and winter, thereby guarantees its heat exchange efficiency.
Described evaporimeter 9 has four mouths of pipe; Be down-comer, tedge, water inlet and venthole; Heat exchange heat pipe 11 in down-comer and tedge and the pedestal 10 forms the circulation line of sealing, and what then form between water inlet and the venthole is open circulation line.During use; Circulation fluid absorbs heat energy and becomes steam from coke oven furnace roof hollow place 1, flow to the tedge place of evaporimeter 9 then, gets into evaporimeter 9 inner water sources from water inlet and then carries out forming steam after the heat exchange with this high-temperature steam; Emit from venthole then; And the circulation fluid in the pipeline becomes liquid after discharging heat energy, flows back to heat exchanger 8 inside from down-comer, participates in circulation again.
As stated, just can realize the utility model preferably.
