Abstract
The utility model discloses a boiler with cooling function, including the boiler body, this internal furnace that has of this boiler is provided with intercommunication to furnace's primary air fan and overfire fan on this boiler body respectively, is connected with a high-pressure steam pipe in this overfire fan's import department, is provided with a valve on this high-pressure steam pipe, the external high-pressure steam pipeline of this high-pressure steam pipe. The utility model provides a boiler with cooling function can effectively reduce the inside temperature of boiler, makes the temperature drop to below 1000 ℃, and the cooling is effectual to extension boiler life-span.
Description
Technical Field
The utility model relates to a boiler field especially relates to a boiler with cooling function.
Background
The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. During operation of the boiler, the internal temperature is high, typically up to 1000 ℃, and when the temperature exceeds 1000 ℃, the life of the boiler is severely affected.
The existing boiler is not provided with a cooling device, but the cooling device is too complex in structure and poor in cooling effect.
SUMMERY OF THE UTILITY MODEL
To the above, an object of the utility model is to provide a boiler with cooling function can effectively reduce the inside temperature of boiler, makes the temperature drop to below 1000 ℃, and the cooling is effectual to extension boiler life-span.
The utility model discloses a reach the technical scheme that above-mentioned purpose adopted and be:
the utility model provides a boiler with cooling function, includes the boiler body, has a furnace in this boiler body, is provided with the primary air fan and the secondary air fan that feed to furnace on this boiler body respectively, its characterized in that is connected with a high-pressure steam pipe in this secondary air fan's import department, is provided with a valve on this high-pressure steam pipe, the external high-pressure steam pipeline of this high-pressure steam pipe.
As a further improvement of the utility model, the upper end of the furnace is provided with a main steam outlet.
As a further improvement of the utility model, be provided with overfire air fan entry and overfire air fan export on the furnace lateral wall, this overfire air fan passes through overfire air fan pipe connection to overfire air fan entry, and this high pressure steam pipe is linked together with the overfire air fan pipeline.
As a further improvement of the utility model, be provided with primary air fan entry and primary air fan export on the furnace lateral wall, this primary air fan passes through primary air fan pipe connection to primary air fan entry.
The utility model has the advantages that: through connecting high-pressure steam pipe in the import department at secondary fan, when secondary fan blew air in toward furnace, the high-pressure steam that lets in by high-pressure steam pipe mixes with the air of blowing in, makes the air moist, and moist air gets into in the furnace, can effectively reduce the furnace internal temperature, makes the temperature drop to below 1000 ℃, and the cooling is effectual to extension boiler life.
The above is an overview of the technical solution of the present invention, and the present invention is further explained with reference to the accompanying drawings and the detailed description.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.
Referring to fig. 1, an embodiment of the present invention provides a boiler with a cooling function, including a boiler body 1, a furnace 11 is provided in the boiler body 1, a primary air fan and a secondary air fan 3 communicated to the furnace 11 are respectively provided on the boiler body 1, a high pressure steam pipe 4 is connected to an inlet of the secondary air fan 3, a valve 41 is provided on the high pressure steam pipe 4, and the high pressure steam pipe 4 is externally connected to a high pressure steam pipeline.
In this embodiment, a main steam outlet 111 is provided at the upper end of the furnace 11.
In the embodiment, a secondary fan inlet 112 and a secondary fan outlet 113 are arranged on the side wall of the hearth 11, the secondary fan 3 is connected to the secondary fan inlet 112 through a secondary fan pipeline 31, and the high-pressure steam pipe 4 is communicated with the secondary fan pipeline 31.
In this embodiment, a primary air fan inlet 114 and a primary air fan outlet 115 are provided on the side wall of the furnace 11, and the primary air fan is connected to the primary air fan inlet 114 through a primary air fan pipe.
Through connecting high pressure steam pipe 4 at the import department of overfire fan 3, when overfire fan 3 blew air into 11 in the furnace, the high pressure steam that lets in by high pressure steam pipe 4 mixes with the air of blowing in, makes the air moist, and moist air gets into 11 in the furnace, can effectively reduce 11 interior temperatures in the furnace, makes the temperature drop to below 1000 ℃ to the extension boiler life-span.
For the opening mode of the high pressure steam pipe 4, the valve 41 can be manually opened, or the valve 41 can be opened in an electric control mode. When the high temperature alarm of the boiler is sounded, the valve 41 is opened, the steam can be introduced from the high pressure steam pipe 4, and when the high temperature alarm is released, the valve 41 is closed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
