Description

Steam power plant boiler exhaust pipeline

Technical Field

The utility model relates to a power plant field, concretely relates to steam power plant boiler exhaust pipe.

Background

The smoke exhaust pipe is widely used in industrial production. The flue for the thermoelectric plant is a cylindricality siphunculus usually, because the tub service environment of discharging fume that the thermoelectric plant used is abominable, be corroded especially the season that the rainwater is frequent very easily, cause use cost higher, in order to prevent that it from receiving the corruption of outside rainwater, need be at tub top installation rain shield of discharging fume, but great rainwater can be touch to the inevitable of installation rain shield, also can enter into and discharge fume intraductally cause its corruption, and also the flue gas when entering into the pipe of discharging fume from advancing the tobacco pipe also has impurity, it can be stopped up with it from the impurity of the pipe top entering of discharging fume through long-term accumulation, influence the efficiency of discharging fume.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a thermal power plant boiler exhaust pipe.

The utility model discloses a realize through following technical scheme:

the utility model provides a steam power plant boiler exhaust pipe, is including advancing tobacco pipe and exhaust pipe, it is fixed with the pipe intercommunication of discharging fume through the connecting pipe to advance the tobacco pipe, the top of the pipe of discharging fume is provided with the rain shade that is used for keeping off the rain, the lower part of the pipe of discharging fume is provided with the collecting pipe rather than the intercommunication, the collecting pipe bottom is fixed with the downtake through the bolt, be provided with the umbelliform filter mantle in the collecting pipe, the top of umbelliform filter mantle is fixed with annular shield mantle, the lower part that annular shield mantle is provided with a plurality of and opens the discharge orifice on the umbelliform filter mantle, be provided with on the lateral wall of umbelliform filter mantle and be used for with the sealed sealing washer of collecting pipe inner wall, the bottom of umbelli.

Preferably, the outer diameter of the umbrella-shaped filter cover is matched with the inner diameter of the collecting pipe.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality is through setting up the collecting pipe in the lower part of tub of discharging fume to set up umbrella form filter mantle that can convenient to detach in the collecting pipe, effectually prevented the jam of tub of discharging fume.

FIG. 2 is a schematic partial cross-sectional view of FIG. 1;

FIG. 3 is another perspective view of FIG. 2;

FIG. 4 is a schematic enlarged view of a portion of the structure of FIG. 3;

in the figure: the device comprises a smoke inlet pipe 1, a connecting pipe 2, a smoke exhaust pipe 3, a rain shield 4, a collecting pipe 5, a down pipe 6, a bolt 7, an umbrella-shaped filter cover 8, a sealing ring 9, an annular shield cover 10, a water flowing hole 11 and a handle 12.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, 2, 3 and 4, a smoke exhaust pipeline of a boiler of a thermal power plant comprises a smoke inlet pipe 1 and a smoke exhaust pipe 3, wherein the smoke inlet pipe 1 is fixedly communicated with the smoke exhaust pipe 3 through a connecting pipe 2, a rain shield 4 for shielding rain is arranged at the top of the smoke exhaust pipe 3, a collecting pipe 5 communicated with the smoke exhaust pipe 3 is arranged at the lower part of the smoke exhaust pipe 3, the bottom of the collecting pipe 5 is fixed with a descending pipe 6 through a bolt 7, an umbrella-shaped filter cover 8 is arranged in the collecting pipe 5, an annular shield cover 10 is fixed at the top of the umbrella-shaped filter cover 8, a plurality of water flow holes 11 formed in the umbrella-shaped filter cover 8 are formed in the lower part of the annular shield cover 10, a sealing ring 9 for sealing with the inner wall of the collecting pipe 5 is arranged on the side wall of the umbrella-shaped filter cover 8, and a handle 12 is fixed at the bottom.

The outer diameter of the umbrella-shaped filter cover 8 is matched with the inner diameter of the collecting pipe 5.

The working principle is as follows: when the utility model is used, the smoke enters the smoke exhaust pipe 3 through the smoke inlet pipe 1 and the connecting pipe 2 and is discharged from the top of the smoke exhaust pipe 3, part of the rainwater entering the smoke exhaust pipe 3 can enter the collecting pipe 5 when raining in rainy season, and is gathered at the side edge of the umbrella-shaped filter cover 8, and can be mixed with impurities contained in the smoke when entering the smoke exhaust pipe 3 from the smoke inlet pipe 1, the impurities are positioned at the lower part of the edge of the umbrella-shaped filter cover 8, after a period of precipitation, the supernatant at the upper part can overflow to the lower part of the umbrella-shaped filter cover 8 through the drain hole 11 and is finally discharged from the downcomer 6, and the supernatant is recycled by a barrel for cleaning, after long-term impurity accumulation at the edge of the umbrella-shaped filter cover 8, the bolt 7 can be periodically unscrewed, the downcomer 6 is taken down, the handle 12 is held by hands to pull the umbrella-shaped filter cover 8 downwards to be discharged from the collecting pipe 5, and the impurities on the inner walls of the umbrella-shaped filter, reach convenient quick jack-up desilting effect, effectually prevented the jam of discharging fume pipe 3, the sealing washer 9 that sets up can effectually prevent the seepage of impurity liquid mixture, and the annular that sets up shelters from cover 10 and has effectually guaranteed that the rainwater that comes in from discharging fume pipe 3 is directly got rid of from discharge orifice 11, guarantees the effect that impurity deposits.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
