Description

Melting furnace
Technical field
The utility model relates to a kind of firing equipment, is specifically related to a kind of melting furnace.
Background technology
In Chemical Manufacture, often need needs chemical solution being carried out to Fast Heating, common mode adopts melting furnace mixed coal gas producer to heat, and gas generator often needs to adopt coal to carry out high-temperature fusion granulation as material, to environment, so the heat absorption efficiency improving melting furnace equals the use amount reducing coal, namely reduces the pollution to environment.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is the melting furnace providing a kind of heat absorption efficiency high.
For achieving the above object, the utility model provides following technical scheme: comprise body of heater and be positioned at several heat absorbing conduits of body of heater inner chamber, it is characterized in that: described body of heater is that tubular is arranged, the opening of one end of the length direction of this tubular is as hot gas inlet, the opening of the other end is as heat outlet, described each heat absorbing conduit take the shape of the letter U shape arrange, the two ends of this U-shape are respectively as inlet and liquid outlet, the both sides of this U-shaped parallel with body of heater length direction and center line about body of heater length direction is symmetrical arranged, the turning of this U-shaped near the hot gas inlet of body of heater and opening towards heat outlet.
By adopting technique scheme, the heat absorbing conduit arranged that takes the shape of the letter U makes the body of heater of unit length can carry out the heat exchange of double length, and solution is more slow at the flow velocity at the turning of U-shaped, it is allowed to aim at hot gas inlet, the saturated thermal current of the heat making just to enter body of heater, with the solution sufficient heat exchange in longer time and heat absorbing conduit, makes heat absorption efficiency increase.
The utility model is set to further: the described heat absorbing conduit being positioned at same level is one group, and each group of described heat absorbing conduit is in vertically setting gradually, and u turn place of the heat absorbing conduit of described same group is that concentric semicircle shape is arranged.
By adopting technique scheme, the heat absorbing conduit of much more vertical group arrangement increases heat absorbing conduit quantity, and u turn place of the heat absorbing conduit of same group is the arrangement compactedness that concentric semicircle shape then increases heat absorbing conduit, reduces melting furnace overall volume.
The utility model is set to further: the chamber wall of described body of heater inner chamber is provided with along its length in wavy fluctuating block.
By adopting technique scheme, fluctuating block can stop the thermal current of the chamber wall near body of heater inner chamber, slow down the circulating rate in its relative length direction, namely extend it and persist the time at inner chamber, secondly, make in wavy setting thermal current form convolution, while hindering other air-flows, repeatedly heat exchange is carried out to heat absorbing conduit.
The utility model is set to further: described body of heater inner chamber chamber wall is coated with heat-insulation layer.
By adopting technique scheme, heat-insulation layer avoids the heat losses of the thermal current of body of heater inner chamber, increases heat utilization ratio further, reduces the use amount of coal.
The utility model is set to further: the cavity outer peripheral face of described heat absorbing conduit circumferentially setting gradually oriented heat absorbing conduit sunken inside.
By adopting technique scheme, arranging cavity makes heat absorbing conduit increase with the contact area of extraneous heat exchange, the lasting heat exchange in cavity and part thermal current can circle round, extend heat exchange duration on the one hand, increase heat exchange efficiency, reduce the solution passed through in heat absorbing conduit on the other hand, the heat that the solution increasing unit volume absorbs, accelerate degree of heat.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the horizontal cross-section schematic diagram of the utility model detailed description of the invention;
Fig. 2 is the vertical cross-section schematic diagram of the utility model detailed description of the invention;

Detailed description of the invention
As shown in Fig. 1-Fig. 3, the utility model discloses a kind of melting furnace, comprise body of heater 1 and be positioned at several heat absorbing conduits 3 of body of heater inner chamber 2, body of heater 1 is arranged in tubular, the opening of one end of the length direction of this tubular is as hot gas inlet 11, the opening of the other end is as heat outlet 12, each heat absorbing conduit 3 take the shape of the letter U shape arrange, for clear expression structure, it is the simple technique of painting in Fig. 1 and Fig. 2, center line in Fig. 1 represents the track of heat absorbing conduit 3, the intersection of the dotted line in Fig. 2 represents the end of heat absorbing conduit 3, the two ends of this U-shape are respectively as inlet 31 and liquid outlet 32, the both sides of this U-shaped parallel with body of heater length direction and center line about body of heater length direction is symmetrical arranged, the turning of this U-shaped near the hot gas inlet 11 of body of heater and opening towards heat outlet 12, the heat absorbing conduit 3 arranged that takes the shape of the letter U makes the body of heater 1 of unit length can carry out the heat exchange of double length, and solution is more slow at the flow velocity at the turning 33 of U-shaped, it is allowed to aim at hot gas inlet, the saturated thermal current of the heat making just to enter body of heater 1 is with the solution sufficient heat exchange in longer time and heat absorbing conduit, heat absorption efficiency is increased.
The heat absorbing conduit 3 being positioned at same level is one group, each group of heat absorbing conduit 3 is in vertically setting gradually, u turn place 33 of the heat absorbing conduit 3 of same group is that concentric semicircle shape is arranged, the heat absorbing conduit 3 of vertical many group arrangements increases heat absorbing conduit quantity, u turn place 33 of the heat absorbing conduit 3 of same group is the arrangement compactedness that concentric semicircle shape then increases heat absorbing conduit, reduces melting furnace overall volume.
