The rectifying tower has high heating speed, high heating efficiency, and high heat energy utilization rate, and can uniformly heat materials, therefore the rectifying quality of the rectifying tower is increased.
Description
Technical field
The utility model relates to a kind of rectifying column, relates in particular to a kind of no benzene paint solvent rectifying column.
Background technology
Along with China's rapid development of economy, industrial enterprise's pollution problem is more and more serious.For adding solvent in the production process of producing paint, these solvents generally all are employing toluene, dimethylbenzene, acetone, contain benzoline etc., it is very big to the production and the use toxicity of product of paint that these contain benzene solvent, had a strong impact on the healthy of worker, also polluted environment.And the appearance of not having the benzene paint solvent has replaced the key that the raw material that contains benzene is prevention benzene poisoning and environmental pollution, need to use rectifying column in the production of non-toluene solvent, traditional rectifying column comprises a tower body, be provided with the steam pipe of heating usefulness in the tower body, steam pipe generally is to adopt Dan Congguan, adopt the Dan Congguan firing rate slow, efficient is low, utilization rate to heat energy is lower, the Dan Congguan heat medium flows from the bottom up simultaneously, make the temperature of charge on tower body bottom and top inconsistent, heat inhomogeneously, influence the quality of its distillation.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of no benzene paint solvent rectifying column is provided, and this rectifying column firing rate is fast, efficiency of heating surface height, and heat energy utilization rate height, and to the material homogeneous heating, thereby the distillation quality of raising rectifying column.
For solving the problems of the technologies described above, the technical solution of the utility model is: no benzene paint solvent rectifying column, comprise tower body, the bottom of described tower body is provided with steam inlet pipe, the top of described tower body is provided with steam outlet pipe, be provided with second heat(ing) coil that first heat(ing) coil that vertically spirals and level are spiraled and be provided with in the described tower body, described first heat(ing) coil and second heat(ing) coil are communicated with described steam inlet pipe and steam outlet pipe respectively.
As a kind of preferred scheme, described first heat(ing) coil spirals to wrap and is assisting described second heat(ing) coil.
As a kind of preferred scheme, described second heat(ing) coil spirals and is wrapped in described first heat(ing) coil.
As a kind of preferred scheme, be provided with the fixed mount of fixing described first heat(ing) coil in the described tower body.
As a kind of preferred scheme, be provided with the fixed mount of fixing described second heat(ing) coil in the described tower body.
After having adopted technique scheme, effect of the present utility model is: because described no benzene paint solvent rectifying column, comprise tower body, the bottom of described tower body is provided with steam inlet pipe, the top of described tower body is provided with steam outlet pipe, be provided with second heat(ing) coil that first heat(ing) coil that vertically spirals and level are spiraled and be provided with in the described tower body, described first heat(ing) coil and second heat(ing) coil are communicated with described steam inlet pipe and steam outlet pipe respectively, therefore, feed heat medium to steam inlet pipe, heat medium flows out from steam outlet pipe through flowing in first heat(ing) coil and second heat(ing) coil respectively, in tower body, in the process of flowing material in the tower body is heated, because first heat(ing) coil vertically spirals, and being level, second heat(ing) coil spirals, like this, when heat medium flows at first heat(ing) coil, guaranteed the material heating-up temperature basically identical of tower body upper and lower, and heat medium is when flowing in second heat(ing) coil, guaranteed the material heating-up temperature basically identical of tower body horizontal direction, thereby make the material heating-up temperature in the whole tower body even, and because the dual of the heat medium of first heat(ing) coil and second heat(ing) coil flowed, it is fast to compare the Dan Congguan firing rate, efficiency of heating surface height, heat energy utilization rate height, and to the material homogeneous heating, thereby the distillation quality of raising rectifying column.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure cutaway view of the utility model embodiment;
In the accompanying drawing: 1. tower body; 2. steam inlet pipe; 3. steam outlet pipe; 4. first heat(ing) coil; 5. second heat(ing) coil; 6. fixed mount; 7. discharging tube; 8. distill mouth.
The specific embodiment
A kind of no benzene paint solvent rectifying column, as shown in drawings, it comprises tower body 1, described tower body 1 is provided with charging aperture, and the top is provided with distillation mouth 8, and the bottom is provided with discharging tube 7, the bottom of described tower body 1 is provided with steam inlet pipe 2, the top of described tower body 1 is provided with steam outlet pipe 3, is provided with second heat(ing) coil 5 that first heat(ing) coil 4 that vertically spirals and level are spiraled and be provided with in the described tower body 1, and described first heat(ing) coil 4 and second heat(ing) coil 5 are communicated with described steam inlet pipe 2 and steam outlet pipe 3 respectively.The mounting means of described first heat(ing) coil 4 and second heat(ing) coil 5 has two kinds of forms.A kind of form is that described first heat(ing) coil 4 spirals and is wrapped in described second heat(ing) coil 5.Be provided with the fixed mount 6 of fixing described first heat(ing) coil 4 in the described tower body 1.Described fixed mount 6 is to be fixed on tower body 1 madial wall, and first heat(ing) coil 4 is fixed on the fixed mount 6, and described second heat(ing) coil 5 is fixed on the inner ring of described first heat(ing) coil 4.Another kind of form is that described second heat(ing) coil spirals and is wrapped in described first heat(ing) coil (this installation form is not represented).Be provided with the fixed mount of fixing described second heat(ing) coil in the described tower body, this fixed mount equally also is to be fixed on the tower body madial wall, and described first heat(ing) coil then is to be fixed on the inner ring of described second heat(ing) coil.
Operation principle of the present utility model is: during work, material is joined in the tower body 1 by charging aperture, feed heat medium to steam inlet pipe 2, heat medium flows out from steam outlet pipe 3 through flowing in first heat(ing) coil 4 and second heat(ing) coil 5 respectively, in tower body 1, in the process of flowing material in the tower body 1 is heated, the product that produces after the distillation gasification enters next operation through distillation mouthful 8 discharge tower bodies 1, and the liquid after retaining is then discharged from discharging tube 7.Because first heat(ing) coil 4 vertically spirals, and second heat(ing) coil 5 is that level is spiraled, like this, when heat medium flows at first heat(ing) coil 4, guaranteed the material heating-up temperature basically identical of tower body 1 upper and lower, and heat medium is when flowing in second heat(ing) coil 5, guaranteed the material heating-up temperature basically identical of tower body 1 horizontal direction, thereby make the material heating-up temperature in the whole tower body 1 even, and because the dual of the heat medium of first heat(ing) coil 4 and second heat(ing) coil 5 flowed, it is fast to compare the Dan Congguan firing rate, efficiency of heating surface height, heat energy utilization rate height, and to the material homogeneous heating, thereby the distillation quality of raising rectifying column.
