Abstract
The utility model discloses a baffle plate specialized for an inlet duct of a kiln end exhaust heat boiler, which comprises a plurality of baffle plate blocks (1). The utility model is characterized in that: one edge of each baffle plate block (1) is fixedly connected with a steel plate (2), and the other edge is fixedly connected with a steel plate (3); when closing connection is performed for every two baffle plate blocks (1), the steel plate (2) and the steel plate (3) between the baffle plate blocks (1) are closely connected vertically through a closing way. The leakage rate is reduced, and the efficiency of an exhaust heat power-generation system is greatly improved.
Description
Technical field
The utility model relates to the cement kiln waste-heat power generation system technical field, particularly relates to a kind of kiln tail waste heat boiler inlet cigarette wind special baffle of cement kiln waste-heat power generation system.
Background technology
Along with implementing of the energy-conservation industrial policy of country, cement kiln residual heat generating is built like a raging fire.
Chinese patent ZL200720187416.4 discloses the device of a kind of silicon-aluminum alloy electric furnace gas cleaning and UTILIZATION OF VESIDUAL HEAT IN, the smoke intake pipeline of aerial cooler is connected with the electric furnace flue gas discharge tube in this device, and the flue that goes out of aerial cooler is connected with the inlet flue gas pipeline of sack cleaner.Be equipped with mixer selector valve on the outlet flue of aerial cooler, the gas approach place of sack cleaner is equipped with the temperature monitoring point.Aerial cooler is equipped with the inertia baffle plate with being connected of sack cleaner in the flue, the below of inertia baffle plate is equipped with ash bucket.The gas approach place of sack cleaner is equipped with ash-spraying valve.The outlet flue of sack cleaner is divided into two-way, and wherein one road flue is connected with the gas approach of drying kiln, and another road flue of the exhaust pass of drying kiln and sack cleaner converges through air-introduced machine and is connected with chimney.
Along with the development of cement kiln residual heat generating technology, cement kiln waste-heat power generation system high-temperature flue baffle plate also must constantly obtain tremendous development for adapting to improving of cement kiln generation technology.
Cement kiln waste-heat power generation system high-temperature flue inlet cigarette wind (valve) baffle plate is different from general thermal power plant baffle plate, thermal power plant's baffle plate is generally in indoor installation, working media generally is clean air, the effect of inlet cigarette windshield plate mainly is the adjusting of air quantity, there are not baffle plate high temperature deformation and dust wear problems, material generally adopts the welding of Q235 steel plate, and very thin thickness, mostly below 6mm.And cement kiln waste-heat power generation system flue-gas temperature height (350～450 ℃) and contains that a large amount of dust, gas speed is high, negative pressure is big, particularly kiln tail dustiness reach 80mg above, more than the negative pressure 7000Pa.As adopting same this baffle plate again, will cause the baffle plate distortion, it is stuck baffle plate to occur, leaks to increase, and has wasted the large quantity of exhaust gas resource, and flow can't be regulated.
And, with regard to cement kiln waste-heat power generation system itself, the leakage rate of valve is related to the generated energy in waste heat power station, and very big to the generated energy influence as leaking out of SP waste heat boiler (being kiln tail boiler) bypass (valve), bypass valve whenever leaks out 1%, generated energy descends 0.6%, therefore must strictly control, designing requirement bypass valve air leak rate of air curtain is 1%, the most very much not should surpass 1.5%, but actual conditions are far longer than 1.5%, even reach 5%--10%; Too, the bypass valve slip is big, equally also can reduce the quality of flue gas, causes AQC stove undercapacity for AQC waste heat boiler (being that the kiln hood boiler is vertical).
As shown in Figure 1, the various inlet cigarette windshield plates of prior art, generally about 2%, much all more than 5%, it has influenced the efficient of afterheat generating system to its processed finished product slip greatly.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and a kind of kiln tail waste heat boiler inlet cigarette wind special baffle is provided.It has reduced slip, has improved the efficient of afterheat generating system greatly.
A kind of kiln tail waste heat boiler inlet cigarette wind special baffle for realizing that the purpose of this utility model provides comprises a plurality of baffle plate pieces, and each described baffle plate piece is edge fixedly connected on one side
The shaped steel plate, another side edge fixedly connected
The shaped steel plate;
When between per two described baffle plate pieces during closed the connection, described between the described baffle plate piece
The shaped steel plate and
Shaped steel plate back-off tight closure up and down connects.
More preferably, described baffle plate piece and
The shaped steel plate and
The shaped steel plate is fixedly connected by welding, rabbet or utilizing screw to be fixedly attached on the described baffle plate piece.
The beneficial effects of the utility model are: kiln tail waste heat boiler inlet cigarette wind special baffle of the present utility model, baffle plate is when reducing air leak rate of air curtain, improve safe handling property, and wearability, make baffle plate in the cement residual heat boiler electricity generation system, bring into play safer effect more efficiently.
Description of drawings
Fig. 1 is the kiln tail waste heat boiler inlet cigarette wind special baffle structural representation of prior art;
Fig. 2 is a kiln tail waste heat boiler inlet cigarette wind special baffle structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, kiln tail waste heat boiler inlet cigarette wind special baffle of the present utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein is only in order to explanation the utility model rather than to restriction of the present utility model.
As shown in Figure 2, kiln tail waste heat boiler inlet cigarette wind special baffle of the present utility model comprises a plurality of baffle plate pieces 1, and each described baffle plate piece 1 is edge fixedly connected on one side
Shaped steel plate 2, another side edge fixedly connected
Shaped steel plate 3;
When closure connects between per two described baffle plate pieces 1, a baffle plate piece 1
Shaped steel plate 2 and another baffle plate piece
The shaped steel plate is the connection of back-off tight closure about in the of 3, forms the seal form as labyrinth seal, so just greatly reduces slip, and
Shaped steel plate 2 Hes
Shaped steel plate 3 connects, and has also strengthened the intensity of baffle plate.
Preferably, baffle plate piece 1 He
Shaped steel plate 2 Hes
Shaped steel plate 3 is fixedly connected by welding, rabbet or utilizing screw to be fixedly attached on the described baffle plate piece 1.
Kiln tail waste heat boiler inlet cigarette wind special baffle of the present utility model, through experiment test, the final slip of baffle plate after the improvement can reduce more than 50%, be that slip is controlled in 1%, reached the inleakage of bypass when reducing boiler operatiopn, thereby improve the operational efficiency of cement kiln waste-heat power generation system, improve generated energy.
Should be noted that at last that obviously those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these revise and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification.
