Description
Technical field
The utility model relates to a kind of vapour generator, is specifically related to a kind of steamer being applied to heat treatment furnace.
Background technology
Under normal circumstances, when heat treatment furnace utilizes Sweet natural gas to heat metal works, the flue gas of a large amount of temperatures as high 300-700 DEG C can be produced in stove, and traditional heat treatment furnace is often direct drains into outside stove by this high-temperature flue gas, not only cause environmental pollution, the also serious waste energy, increases the discharge of greenhouse gases.
In order to address this problem, existing a lot of heat treatment furnace realizes the waste heat recovery of furnace high-temperature flue gas by arranging interchanger, the heat reclaimed as required heat hot water, there is steam as process furnace moisturizing and domestic water, or add warm air and be used as combustion air in stove.Existing heat treatment furnace interchanger is generally water tank, be filled with water boiler, and it can realize the recycling of flue gas heat to a certain extent.But its major defect existed is: 1, interchanger is all arranged at outside stove by most of heat treatment furnace, such as in patent CN203857826U, heat treatment furnace establishes the many bends collecting high-temperature gas to be vented tracheae in furnace roof outside and the exhaust the other end of tracheae is connected with the burner hearth of boiler.High-temperature flue gas in stove is entering in the process of boiler furnace by the outer gas exhaust duct of stove, and the most of heat in flue gas has diffused in air, then causes serious energy dissipation.2, in flue gas heat recycling process, usually the water directly contacted with water tank or the boiler internal surface that is filled with water is only had to be heated rapidly, the inner off-centre water of water tank then heats slower, and now most flue gas has been discharged in air usually, therefore lower to the heat recovery and utilization rate of high-temperature flue gas.3, due to the water that high-temperature flue gas direct heating contacts with water tank or boiler internal surface, then make the water local temperature that contacts with water tank internal surface higher.In addition, the shape of water tank is generally rectangular parallelepiped, square or right cylinder, and the high-temperature water directly contacted with water tank surface can cause water tank to produce stress deformation usually, then shortens the work-ing life of water tank.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of to be arranged in heat treatment furnace and flue gas heat recovery utilization rate is high, the steamer that is heated evenly, not easily produces stress deformation, stabilized structure.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of steamer being applied to heat treatment furnace, comprise heat treatment furnace, described heat treatment furnace inwall furnace roof installs steamer, described steamer comprises at least one tank, described tank comprises the first seamless tube, outside sheathed second seamless tube of described first seamless tube, two ends of described first seamless tube and the second seamless tube are connected by seamless tube joint flange and seal, and described tank is provided with the steam duct connected with the second seamless tube.
Seamless tube described in the utility model is the right cylinder tubing of hollow.Furnace high-temperature flue gas directly heats through tank first seamless tube inside the water contacted with the first seamless tube outside surface, the outside surface that simultaneously high-temperature flue gas is directly coated on tank second seamless tube heat the water contacted with the second seamless tube internal surface, makes the water heating in whole tank rapid and even.
As preferably, described steamer comprises three tanks, is arranged side by side and is interconnected by pipeline through between three tanks, and the steam duct of tank described in one of them is connected through with the steam duct of adjacent two tanks.Because the steam duct of alternate two tanks is all connected through with the steam duct of middle tank, the steamer be therefore made up of three tanks can form firm triangular structure.
As preferably, be provided with branch drain bottom the second seamless tube of described tank, described branch drain is all connected with total pipeline, the setting of described drainage pipeline, and tank can be facilitated to complete the operation such as draining, cleaning.
As preferably, described tank is connected to the inwall furnace roof of heat treatment furnace by erecting frame.The setting of erecting frame can facilitate steamer to be connected with the installation of heat treatment furnace inwall furnace roof.
Preferably, described erecting frame is made up of many square tubes, is provided with insulating cotton between described second seamless tube and square tube.Described insulating cotton the calorific loss that can effectively reduce in tank is set.
Further, described steam duct is seamless tube.
As preferably, described steam duct is provided with steam output pipe, and the steam formed through heating evaporation in tank can be transported to workshop, bathroom or other place and use by described steam output pipe.
The utility model compared with the existing technology has the following advantages and effect:
1, steamer described in the utility model is arranged in heat treatment furnace, and directly can utilize the water in furnace high-temperature flue gas heating tank, flue gas heat recovery utilization rate is higher.
2, the water that the high-temperature flue gas direct heating in heat treatment furnace contacts with tank outside surface and internal surface, makes the water in tank can be heated rapidly and be heated comparatively even.
3, the water in tank is uniformly heated by high-temperature flue gas, and therefore tank described in the utility model can not produce stress deformation due to inside local water temperature over-high.
4, the steamer be made up of three tanks described in the utility model, structure is comparatively firm.
