Abstract
The utility model discloses an internal load-bearing beam of a heat-carrier heating furnace. The internal load-bearing beam is formed by ordinary carbon steel plates (1) in welding mode and is in the structure of a sealed box chamber, a water inlet (2) is arranged in one end portion of the internal load-bearing beam, and a water outlet (3) is arranged in the other end portion of the internal load-bearing beam. When the heat-carrier heating furnace works, cooling water enters the internal load-bearing beam from the water inlet (2) and flows out the internal load-bearing beam from the water outlet (3). At least two flow guiding plates (4) are arranged in the box chamber of the internal load-bearing beam in parallel, and a certain distance is arranged between the two flow guiding plates. A safety pressure relief pipe connecting opening (5) is further formed in the internal load-bearing beam, and the internal load-bearing beam is connected with a safety pressure relief valve through the safety pressure relief pipe connecting opening (5). Even though the internal load-bearing beam is in a high-temperature environment in the furnace, the temperature of the internal load-bearing beam does not rise, and the internal load-bearing beam of the heat-carrier heating furnace is simple in structure, low in price, long in service life and suitable for being popularized and utilized in heat-carrier heating furnaces.
Description
Technical field
The utility model relates to a kind of heat medium heater, particularly relates to the bearing beam in the heat medium heater stove.
Background technology
As everyone knows, bearing beam in the heat medium heater stove is in the interior hot environment of stove mostly, these bearing beams are both stressed, be heated again, thereby usually by can be high temperature resistant, can bear again the high temperature resistant precious metal material of larger external force and make, material commonly used has 1Gr18Ni9Ti, 15GrMo, 12Gr1MoV etc.There is the defective of following two aspects in the bearing beam of this structure, on the one hand, the production cost of bearing beam is higher, on the other hand, because these resistances to elevated temperatures by the bearing beam that high temperature resistant precious metal material is made are often limited, sometimes can't reach the desired effect of product design fully, thereby become a bottleneck of restriction heat medium heater industry development.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cheap, need not adopt that high temperature resistant precious metal material and performance are better, bearing beam in the heat medium heater stove of longer service life.
For solving the problems of the technologies described above, the utility model adopts bearing beam in a kind of like this heat medium heater stove, this bearing beam is the case cell structure of the sealing that is welded by the ordinary carbon steel plate, end at this bearing beam is provided with water inlet, the other end at bearing beam is provided with delivery port, when heat medium heater was worked, cooling water entered from the water inlet of described bearing beam, from the water outlet outflow of bearing beam.
In the utility model, at the indoor deflector that is provided with at least two space certain distances, is parallel to each other and arranges of the case of described bearing beam.
As a kind of preferred embodiment of the present utility model, on described bearing beam, also offer a safety relief and take over mouth, this bearing beam is taken over mouth through described safety relief and is linked to each other with a safety relief valve.
After adopting said structure, the utlity model has following beneficial effect:
The utility model adopts logical water-cooled mode in bearing beam, because current cooling, though thereby bearing beam is in the hot environment, but the temperature of itself can't raise, therefore on the one hand, bearing beam of the present utility model can adopt ordinary carbon steel to make and get final product, and no longer needs to adopt the resistant to elevated temperatures precious metal material of energy; On the other hand, bearing beam of the present utility model can not produce Oxidative demage, has solved the difficult problem of ordinary carbon steel oxidized destruction in hot environment.
Bearing beam of the present utility model can be high temperature resistant in the furnace high-temperature environment, can bear larger external force again, compares with the bearing beam that adopts high temperature resistant precious metal material to make, and is under equal conditions cheap, and performance is more superior, and service life is also longer.
Bearing beam of the present utility model is when having served as structure in the stove spare function, or good water preheater can provide for boiler the feedwater of required heat, is used for admirably the recycling of heat energy.
Bearing beam of the present utility model is taken over by safety relief and mouthful is linked to each other with a safety relief valve, can guarantee like this in hot environment, at any time can both safety relief, and security performance is good.
Be provided with deflector in the bearing beam of the present utility model so that the beam body in current even everywhere, current in the beam body without the dead angle.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of bearing beam in the utility model heat medium heater stove.
Fig. 2 is along the generalized section of A-A line among Fig. 1.
The specific embodiment
Referring to bearing beam in Fig. 1, a kind of heat medium heater stove shown in Figure 2, this bearing beam is the case cell structure of the sealing that is welded by ordinary carbon steel plate 1, end at this bearing beam is provided with water inlet 2, the other end at bearing beam is provided with delivery port 3, when heat medium heater is worked, cooling water enters from the water inlet 2 of described bearing beam, from delivery port 3 outflows of bearing beam.
For making the current in the beam body even everywhere, without the dead angle, the utility model is at the indoor deflector 4 that is provided with at least two space certain distances, is parallel to each other and arranges of the case of bearing beam, as shown in Figure 1 in the beam body for current.
For guaranteeing in hot environment, bearing beam at any time can both safety relief, and the utility model also offers a safety relief and takes over mouthfuls 5 on bearing beam, and this bearing beam is taken over mouthfuls 5 through described safety relief and linked to each other with a safety relief valve 6, as shown in Figure 1.
Bearing beam of the present utility model is used for the hot environment in the heat medium heater stove, it is the structural member for load, shape is generally rectangle, adopt the welding of ordinary carbon steel plate to make, can horizontal positioned, also can vertically place, in the beam body circulating water is arranged, can bear larger external force, the utility model also be provided with stove in the water inlet control valve door 7 of temperature interlocking, this water inlet control valve door 7 links to each other with the water inlet 2 of bearing beam by pipeline, when temperature in the stove is elevated to setting value, water inlet control valve door 4 is opened automatically, and the current bearing beam of namely flowing through cools off bearing beam, then discharge from the delivery port 3 of bearing beam, temperature at discharging condensate is higher than ambient temperature, but far below the boiling point of water, draining is pollution-free, can be used as the feedwater that supplies of boiler, when temperature in the stove did not reach the condition of necessary water-cooled, water inlet control valve door 7 was closed, and stopped to supply water.
The utility model is through on probation, though bearing beam is in the hot environment, the temperature of itself does not raise, and has obtained good effect.
