Abstract
A high heating efficiency grate cooler is disclosed by the utility model. In the utility model, a hot blast retaining wall is arranged to act as an interface of high temperature wind and moderate temperature wind or that of moderate temperature wind and lower temperature wind and top of the wall is hung on upper wall of the grate cooler. The utility model adopts the hot blast retaining wall to partition hot blast in upper part of the grate cooler; the hot blast retaining wall can swing, adjust height and make use of hot blast more effectively, improve thermal efficiency of the grate cooler, stabilize secondary and tertiary air temperature of an rotary kiln, save coal consumption and is highly valuable in improving power generation by waste heat and exhaust gas temperature and so on.
Description
(1) technical field
The utility model relates to a kind of cooling machine, particularly a kind of industry cooling machines such as cement industry, Aluminum that are used for.
(2) background technology
At present the cooling air of cooling machine through with the heat exchange of heat material after the hot blast that produced generally all to be recovered utilization, as two, tertiary air is used for replenishing the heat energy of rotary kiln and dore furnace preheater; Oven dry thermal source as coal mill or other facility (as the slag drying system etc.); Can also be as the heat air source of cogeneration; The blast instability of the hot blast recovery area of the cooling machine that exists be unfavorable for the recycling of hot blast, so efficiency of utilization is lower at present.
(3) summary of the invention
The technical problems to be solved in the utility model is: provide a kind of thermal efficiency high cooling machine.
In order to solve the problems of the technologies described above, high temperature wind and the interface of middle temperature wind or the interface of middle Wen Fengyu low temperature wind of the utility model in the cooling machine is provided with the hot blast barricade, and the upper end of hot blast barricade is suspended on the roof of cooling machine.
Described hot blast barricade is made up of the link plate that articulates mutually on the polylith vertical direction.By increasing or reduce the adjusting that link plate is realized the hot blast wall height.
In order to improve the flexibility of hot blast barricade swing, described hot blast barricade top links to each other with the roof of cooling machine by the U-shaped suspension member.
The beneficial effects of the utility model are: the utility model adopts the hot blast barricade to separate to the hot blast on the bed top of combing, height can be swung and can be regulated to the hot blast barricade, energy more efficient use hot blast, improve the thermal efficiency of cooling machine, can stablize two tertiary air temperature, the saving coal consumption of rotary kiln, and high value of practical be arranged at aspects such as improving cogeneration, raising EGT.
(4) description of drawings
Fig. 1 is the utility model partial sectional view;
Fig. 2 is a longitudinal section of the present utility model schematic diagram;
Among the figure: 1, hot blast barricade, 2, high warm material layer, 3, the bed of combing, 4, cooling air.
(5) specific embodiment
The cooling machine that a kind of high heat is as shown in Figure 1 and Figure 2 imitated, the high temperature wind in the cooling machine and the interface of middle temperature wind are provided with hot blast barricade 1, on the comb bed 3 of cooling machine, pile up high warm material layer 2 is arranged, hot blast barricade 1 is in the top of high warm material layer 2, the upper end-face edge of hot blast barricade 1 is provided with hanging scroll, hanging scroll is through in the U-shaped suspension member, and the U-shaped suspension member passes cooling machine roof, and fixing.
In this specific embodiment, hot blast barricade 1 can be designed to be made up of the link plate that articulates mutually on the polylith vertical direction.By the number of increase and decrease link plate, control the height of hot blast barricade 1.Hot blast barricade 1 adopts link plate formula structure, does not influence passing through of big grog ball (piece).
The material of hot blast barricade 1 can be heat-resisting steel part, also can use refractory ceramics.
Claims (3)
1. one kind high cooling machine that heat is imitated, it is characterized in that: the interface of the high temperature wind in the cooling machine and the interface of middle temperature wind or middle Wen Fengyu low temperature wind is provided with hot blast barricade (1), and the upper end of hot blast barricade (1) is suspended on the roof of cooling machine.
2. the cooling machine that a kind of high heat according to claim 1 is imitated, it is characterized in that: described hot blast barricade (1) is made up of the link plate that articulates mutually on the polylith vertical direction.
3. the cooling machine that a kind of high heat according to claim 1 and 2 is imitated, it is characterized in that: described hot blast barricade (1) top links to each other with the roof of cooling machine by the U-shaped suspension member.
