Abstract
The utility model relates to the technical field of evaporators, in particular to a spraying type methanol evaporator. The spraying type methanol evaporator comprises a skirt support, a cylinder body, an evaporation segment, a methanol spraying segment, a separation segment, an overheating segment and a filtration segment, wherein the evaporator is integrally barrel-shaped; the skirt support is arranged at the bottom; the cylinder body is arranged above the skirt support; the evaporation segment is arranged above the cylinder body; a spraying pipe is arranged above the evaporation segment; the separation segment is arranged above the spraying pipe; the overheating segment is arranged above the separation segment; and the filtration segment is arranged above the overheating segment. A raw material feeding manner of the spraying type methanol evaporator can facilitate evaporation and gas-liquid exchange; procedures required to be completed in four devices separately are integrated into one device and completed, so that the overall investment cost is saved; and the procedures are completed in one device, so that heat loss is reduced, liquid drops are not prone to produce, the technology is reasonable, and energy is saved.
Description
Technical field
The utility model relates to a kind of vaporizer, relates in particular to a kind of spray-type methanol evaporator.
Background technology
At present, silver-colored method Formaldehyde Production mainly is divided into two unit operations, and namely oxidizing reaction unit, absorptive unit, oxidizing reaction unit are finished by four devices respectively, i.e. methyl alcohol evaporation, the heating of three vigour, and three vigour are filtered, the oxidizer reaction.It is large to exist the flow process floor space, and the consume of equipment heat energy is large.The factors such as equipment and initial cost are many.
Summary of the invention
The technical problems to be solved in the utility model is: it is large that existing vaporizer exists the flow process floor space, and the consume of equipment heat energy is large.The factors such as equipment and initial cost are many provide a kind of spray-type methanol evaporator.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: this spray-type methanol evaporator comprises group's seat, cylindrical shell, evaporator section, methyl alcohol spray section, segregation section, superheat section and fillter section, described vaporizer integral body is tubbiness, the bottom is provided with group's seat, described group's seat top is provided with cylindrical shell, the top of described cylindrical shell is provided with evaporator section, described evaporator section top is provided with shower, described shower top is provided with segregation section, described segregation section top is provided with superheat section, and described superheat section top is provided with fillter section.
According to another embodiment of the invention, further comprise between described shower and the evaporator section and be provided with chamber.
According to another embodiment of the invention, further comprise in the described segregation section and be provided with scum dredger.
According to another embodiment of the invention, further comprise and be provided with thick effect and efficient combined filtering device in the described fillter section.
According to another embodiment of the invention, comprise that further described evaporator section is internal recycle tubular type structure, is comprised of inner circulating tube, tubulation and housing.
The beneficial effects of the utility model are: the raw material feeding manner of this spray-type methanol evaporator, more be conducive to vaporization, and also more be conducive to the exchange of gas-liquid; Need be incorporated in the device four unaided each process operations of device and finish, save the overall investment cost; Because finishing in a device, calorific loss is few, is difficult for producing drop, and technique is reasonable, save energy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, group seat, 2, cylindrical shell, 3, evaporator section, 4, the methyl alcohol spray section, 5, segregation section, 6, superheat section, 7, fillter section.
Embodiment
Fig. 1 is structural representation of the present utility model, comprise group's seat 1, cylindrical shell 2, evaporator section 3, methyl alcohol spray section 4, segregation section 5, superheat section 6 and fillter section 7 among the figure, described vaporizer integral body is tubbiness, the bottom is provided with group's seat 1, and described group's seat 1 top is provided with cylindrical shell 2, and the top of described cylindrical shell 2 is provided with evaporator section 3, described evaporator section 3 tops are provided with shower 4, described shower 4 tops are provided with segregation section 5, and described segregation section 5 tops are provided with superheat section 6, and described superheat section 6 tops are provided with fillter section 7.
Be provided with chamber between shower 4 and the evaporator section 3.
Be provided with scum dredger in the segregation section 5.
Be provided with thick effect and efficient combined filtering device in the fillter section 7.
Evaporator section 3 is internal recycle tubular type structure, is comprised of inner circulating tube, tubulation and housing.This simple in structure, service efficiency is high.
When the utility model is implemented, formaldehyde enters vaporizer by methyl alcohol spray section 4 in the spray mode, air enters vaporizer by cylindrical shell 2, hot formalin at the bottom of the absorption tower is sent into evaporator section 3 by the product recycle pump, shell side indirect heating evaporator section 3 tube side methyl alcohol and air, make it vaporization and mixing, two vigour segregation section 5 interior through scum dredger except drop, two vigour after the separation are allocated an amount of low-pressure steam at superheat section 6, become three vigour and go top filtration section 7 to carry out gas filtration, make at last clean ternary deoxidation device.
The raw material feeding manner of this spray-type methanol evaporator is conducive to vaporization more, also more is conducive to the exchange of gas-liquid; Need be incorporated in the device four unaided each process operations of device and finish, save the overall investment cost; Because finishing in a device, calorific loss is few, is difficult for producing drop, and technique is reasonable, save energy.
