Abstract
A steam superheater in a cement kiln outlet preheater is characterized in that the inner side pipe of an U-shaped steel pipe and steel plates are installed and welded in circle to form a cyclone tube, the cyclone tube is a high-temperature fume channel, the bottom of the cyclone tube is a high-temperature fume inlet, and the top of the cyclone tube is a high-temperature fume outlet; and the external side pipe and the inner side pipe of the U-shaped steel pipe are respectively communicated with a steam inlet ring header and a steam outlet ring header. Since the temperature in the cyclone tube is reduced by only about 10 DEG C, the whole production process of the preheater can not be affected, while the temperature reduction can greatly play a role on improvement on the taste of steam, particularly on the preheat of saturated steam in the project of cement kiln waste heat generation, and generated energy of the whole cement kiln waste heat generation system is greatly increased.
Description
Technical field
The utility model relates to the steam superheater in a kind of cement kiln tail preheater, in particular for the superheated water stall pure in, the kiln hood of low-temperature cogeneration technology or (with) saturated vapor that produces of kiln tail waste heat boiler.
Background technology
The suspended preheater whirlwind tube of cement kiln tail is a cement kiln tail preheater important component part, and its effect is with the heat transferred cement slurry in the flue gas, thereby reaches the purpose of preheating cement slurry.Simultaneously since the asymptote curved profile and the effect of cement slurry self gravitation of whirlwind tube separate after making cement slurry and flue gas fully mixing, cement slurry after this process is preheated with enter dore furnace after flue gas separates and enter cement rotary kiln again and sinter grog into.Whirlwind tube operation principle is: flue gas and cement slurry mixture enter the whirlwind tube by whirlwind cylinder shell smoke inlet place, flue gas is spinned in the whirlwind tube, and descending rises is again discharged by whirlwind tube inner core, cement slurry in this process and finally enters next process procedure by the cement slurry exit because inertia and self gravitation effect generation dirt fall.
Summary of the invention
Technical problem to be solved in the utility model is in the cement kiln tail preheater steam superheater to be installed.This device can effectively utilize the relatively-high temperature waste heat heat of whirlwind tube, with the saturated vapor heating, thereby produces the superheated steam that is used for cogeneration or other purposes, and in the majority to use C2 level whirlwind tube, and operating mode is the most suitable.
Steam superheater in this cement kiln tail preheater, the inside tube of U-shaped steel pipe and steel plate circumferential arrangement assembly welding constitute the whirlwind tube, the whirlwind tube is the high-temperature flue gas passage, the bottom of whirlwind tube is a high-temperature flue gas entry, the whirlwind tube the top be the high-temperature flue gas outlet; The outboard tube of U-shaped steel pipe and inside tube are connected with steam inlet annular header and steam (vapor) outlet annular header respectively.The inside tube of U-shaped steel pipe and steel plate welding, the whirlwind tube of formation steam superheater.Also be provided with the ash removal equipment for flapping that stretches to the preheater both sides on the steam superheater.
Its operation principle is, flue gas passes through steam superheater from bottom to top, and steam enters steam (vapor) outlet collection case after the inlet header case enters membrane wall heat exchanger tube and flue gas heat exchange, delivers to the steam turbine unit then and is used for generating or other purposes.Flue gas and steam carry out exchange heat by the membrane wall heat exchange, reach the purpose of overheated saturated vapor.
Because the temperature in the whirlwind tube only reduces about 10 ℃, production technology to whole preheater can not have any impact, but very large effect has been played in the lifting to the steam taste, especially for the preheating of saturated steam in the cement kiln residual heat generating project, the generated energy of whole cement kiln waste-heat power generation system is significantly promoted.
Description of drawings
Fig. 1 is the steam superheater structural representation in the cement kiln tail preheater.
The specific embodiment
Now 1 pair of the utility model is further described in conjunction with the accompanying drawings: in cement kiln tail preheater 1 steam superheater is installed, the inside tube of U-shaped steel pipe 4 and steel plate circumferential arrangement assembly welding constitute cylinder, in the cylinder is the high-temperature flue gas passage, the bottom of whirlwind tube is a high-temperature flue gas entry, and the top of whirlwind tube is the high-temperature flue gas outlet; The outboard tube of U-shaped steel pipe 4 and inside tube are connected with steam inlet annular header 2 and steam (vapor) outlet annular header 3 respectively, also are provided with the ash removal equipment for flapping 5 that stretches to preheater 1 both sides on the steam superheater.
Claims (2)
1. the steam superheater in the cement kiln tail preheater, it is characterized in that: the inside tube of U-shaped steel pipe and steel plate circumferential arrangement assembly welding constitute the whirlwind tube, the whirlwind tube is the high-temperature flue gas passage, and the bottom of whirlwind tube is a high-temperature flue gas entry, the whirlwind tube the top be high-temperature flue gas outlet; The outboard tube of U-shaped steel pipe and inside tube are connected with steam inlet annular header and steam (vapor) outlet annular header respectively.
2. the vapor superheater in the cement kiln tail preheater according to claim 1 is characterized in that: also be provided with the ash removal equipment for flapping that stretches to the preheater both sides on the steam superheater.
