Abstract
The utility model discloses a boiler tube waste heat recovery device which comprises a boiler, a steam generator and a smoke channel connected with the boiler. A heat conduction tube is arranged in the smoke channel vertically, the lower end of the heat conduction tube is arranged in the smoke channel, the upper end of the heat conduction tube is arranged outside the smoke channel, the steam generator is arranged on the upper portion of the smoke channel and is isolated from the smoke channel, and the upper end of the heat conduction tube is located in the steam generator. The heat conduction tube is arranged in the smoke channel, boiler waste heat is led out through the heat conduction tube to form steam or hot water or hot air, and the aim of making full use of heat is achieved, and heated clean air such as water or other media can dry materials or be supplemented into the boiler or a pit furnace to be recycled. Heat efficiency of the boiler and the industrial pit furnace is improved, fuel consumption is reduced, and the aim of energy conservation is achieved. Meanwhile, the device is simple in structure and convenient to install and an original boiler or an original industrial pit furnace does not need to be changed during installation.
Description
Technical field
The utility model relates to a kind of back of pipeline receiving apparatus, relates in particular to a kind of back of pipeline receiving apparatus that is applied to boiler industry.
Background technology
At present national each cauldron factory is in the time that industrial fuel oil, combustion gas, coal-burning boiler manufacture and design, can only reach below 75% because a variety of causes causes the specified thermal efficiency of boiler, have more than 25% heat energy to scatter and disappear by flue gas loss, loss of the inadequacy burning for chemistry mechanics reason, unburned carbon loss, body of heater radiation loss, lime-ash physics sensible heat loss etc.Wherein flue gas loss accounts for the more than 90% of total heat loss, and existing a lot of producers utilize common heat exchanger to reclaim the heat of flue gas loss, but the heat exchange efficiency of common heat exchanger is lower, and institute takes up space larger.
Therefore there is defect in prior art.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and it is a kind of for by the boiler tubing retracting device of boiler afterheat recycling, to solve problems of the prior art that the utility model provides.
For achieving the above object, the utility model adopts following technical scheme: a kind of boiler tubing waste-heat recovery device, the exhaust gases passes that it comprises boiler, steam generator and connects boiler, in described exhaust gases passes, be provided with heat pipe, described heat pipe is vertically arranged in exhaust gases passes, described heat pipe lower end is arranged in exhaust gases passes, upper end is arranged on outside exhaust gases passes, described steam generator is arranged on exhaust gases passes top and isolates mutually with it, and the upper end of described heat pipe is arranged in steam generator.
According to an aspect of the present utility model, wherein, described boiler tubing waste-heat recovery device also comprises a clean air pipeline, and it is arranged on exhaust gases passes upper end and isolates mutually with it, and the upper end of described heat pipe is arranged in clean air pipeline.
According to an aspect of the present utility model, wherein, described clean air pipeline below is provided with air blast, for clean air pipeline provides clean air.
According to an aspect of the present utility model, wherein, described heat pipe is set to one or more.
Beneficial effect:
The utility model by arranging heat pipe in exhaust gases passes, boiler afterheat is exported as steam or hot water or hot-air by heat pipe, and to reach making full use of of heat, heat pipe isothermal performance is good, when heat conduction, produce self-vibration and do not produce stifled ash and flowing resistance, remain good heat transfer efficiency.Clean air (water or other media) after heating can material drying or is added in boiler, cellar for storing things stove and recycle.The thermal efficiency that improves boiler and industry cellar for storing things stove, reduces fuel consumption, reaches energy-conservation object.Meanwhile, this apparatus structure is simple, easy for installation, and compact conformation does not need former boiler or Industrial Stoves to change when installation.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of boiler tubing waste-heat recovery device in the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of boiler tubing waste-heat recovery device, the exhaust gases passes 2 that it comprises boiler 1 and connects boiler, on described exhaust gases passes, be provided with heat pipe 3, described heat pipe 3 is vertically arranged in exhaust gases passes, described heat pipe 3 lower ends are arranged in exhaust gases passes, and upper end is arranged on outside exhaust gases passes.Described heat pipe 3 is set to super heat-conductive pipe, and it is heat conduction original paper, in the efficiency of itself and common heat exchanger, improves a lot.Heat pipe isothermal performance is good, produces self-vibration and do not produce stifled ash and flowing resistance when heat conduction, remains good heat transfer efficiency.
Described boiler tubing waste-heat recovery device also comprises steam generator 4, and described steam generator 4 is arranged on exhaust gases passes 2 tops and isolates mutually with it, and the upper end of described heat pipe 3 is arranged in steam generator.High-temperature flue gas is discharged by lower end passage, when discharge, high-temperature flue gas washes away heat pipe, in the time that flue-gas temperature is greater than 30 degrees Celsius, heat pipe is activated and just automatically conducts heat to upper end, at this moment heat pipe lower end heat absorption, upper end heat release, the heat energy of high-temperature flue gas is delivered in upper steam generator endlessly, for steam generator provides heat.Clean air (water or other media),
Described boiler tubing waste-heat recovery device also comprises a clean air pipeline 5, and it is arranged on exhaust gases passes 2 upper ends and isolates mutually with it, and the upper end of described heat pipe 3 is arranged in clean air pipeline.High-temperature flue gas is discharged by lower end passage, when discharge, high-temperature flue gas washes away heat pipe, in the time that flue-gas temperature is greater than 30 degrees Celsius, heat pipe is activated and just automatically conducts heat to upper end, at this moment heat pipe lower end heat absorption, upper end heat release, the heat energy of high-temperature flue gas is delivered to endlessly in the clean air pipeline 5 of upper end, for heating the clean air of clean air pipeline 5, described clean air can be for the production of, fuel saving expense, reduce production costs, reduce toxic emission.
Described clean air pipeline below is provided with air blast 6, for clean air pipeline provides clean air.This device volume is little, and compact conformation is installed and do not needed former boiler or industry cellar for storing things stove to change.
