Description

Boiler waste heat recovery system

Technical Field

The utility model relates to a boiler waste heat recovery system.

Background

The temperature of an outlet of a boiler smoke exhaust flue is generally 150-180 ℃, in order to utilize the heat, the water temperature supplied to a boiler is generally increased by additionally arranging an economizer on the boiler smoke exhaust flue, but on one hand, because the water storage capacity of the economizer is small, when the water adding amount of the boiler is large, the water temperature added in the front is high, the water temperature added in the back is low, and the waste heat of the boiler smoke exhaust cannot be fully utilized; on the other hand, due to the structure of the economizer, smoke dust in the smoke gas easily blocks the economizer, so that the waste heat utilization efficiency is influenced. In recent years, some manufacturers have started to modify economizers, and the purpose of the economizers is to recycle the waste heat of the boiler flue gas to the maximum extent. However, various flue gas waste heat recovery schemes are available in the market, and improvement spaces are provided for the rest of heat recovery effects and the use convenience.

SUMMERY OF THE UTILITY MODEL

To the defect that above-mentioned background art exists, the utility model provides a boiler waste heat recovery system.

In order to realize the above energy-saving purpose, the utility model adopts the technical scheme that: the smoke inlet and the smoke exhaust chamber are connected with the smoke exhaust pipe of the boiler through a smoke inlet, and the smoke exhaust chamber is provided with a smoke exhaust port.

Furthermore, a water inlet is arranged above one side of the sealed water tank, and a water outlet is arranged below the other side of the sealed water tank.

Furthermore, an ash discharge port is arranged below the lower smoke chamber.

Furthermore, a ball float valve is arranged in the sealed water tank.

The utility model discloses following beneficial effect has: the utility model discloses a tobacco pipe passes to seal water tank with the heat, with the water heating in the seal water tank, furthest recycle boiler flue gas waste heat, shorten the boiler water boiling time, reduce the required heat energy consumption of boiler water boiling evaporation, reduce boiler fuel consumption, practice thrift and make the vapour cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model discloses a boiler 1 reaches smoke chamber 3 of being connected with boiler exhaust pipe 2, install seal water tank 4 in the smoke chamber 3, one side top of seal water tank 4 is equipped with water inlet 12, the opposite side is issued and is equipped with outlet 13, seal water tank 4 separates into smoke chamber and lower smoke chamber 8 with the smoke chamber, be equipped with ball-cock assembly (not shown) in the seal water tank 4, it passes seal water tank 4 through a plurality of tobacco pipes 9 and is connected with lower smoke chamber 8 to go up the smoke chamber, the below of lower smoke chamber is equipped with ash discharge port 14, it separates into smoke chamber 6 and smoke discharge chamber 7 through baffle 5 to go up the smoke chamber, it is connected with boiler exhaust pipe 2 through advancing smoke port 10 to advance the smoke chamber 6, smoke discharge chamber 7 is equipped with exhaust port 11.

The utility model discloses a theory of operation does:

the flue gas of boiler 1 is discharged into smoke inlet 6 through boiler smoke discharging pipe 2 and then enters lower smoke chamber 8 through smoke pipe 9, the flue gas in lower smoke chamber 8 is discharged into smoke discharging chamber 7 through smoke pipe 9 and then discharged from smoke outlet 11, the water in sealed water tank 4 is heated by the heat of flue gas absorbed by smoke pipe 9, the boiler flue gas waste heat is recycled to the utmost extent, the boiler water boiling time is shortened, the heat energy consumption required by boiler water boiling evaporation is reduced, the boiler fuel consumption is reduced, and the steam generating cost is saved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
