Description
Technical field
This utility model is related to a kind of fresh air dehumidifying system, belongs to dehumidification system technical field.
Background technology
At present, painting, metallic paint and coating varnish in being sprayed in the way of " wet on wet " after electrophoretic coating, and disposably
The technique that the technique of drying is referred to as 3C1B.The technology trends of 3C1B techniques are using painting, high solid color in high solid
Paint and high solid varnish, can improve application linear velocity, reduce the discharge of VOC, in reduction between painting, paint and varnish coating
It is miscible.Apply in high solid to prevent the radiation of ultraviolet using opaque pigment, simultaneously because middle painting thickness height can be prevented
Electrophoretic paint is affected by ultraviolet radiation.
Compared with traditional vehicle coating process, the technique eliminates middle painting baking operation, so as to polishing being applied in reducing, being wiped
The investment of the coating equipments such as net and drying and floor space, improve production efficiency, reduce energy resource consumption.Simultaneously as without in
Polishing operation is applied, thus has saved the personnel needed for polishing and adjuvant expense.But the finish paint in " wet on wet ", varnish spraying process
Between, need to typically increase prebaking technique, that is, remove a large amount of moisture content in finish paint surface, using high temperature（Typically≤100 DEG C）It is dried empty
Gas carrys out the moisture content on quick adsorption finish paint top layer, so as to the solid part reached with varnish " wet on wet " requires, reaches cooling vehicle body
Varnish spraying is required.However, general drying carries out heat temperature raising to sent air using the heater box of indirect heat exchange, in order to protect
Card drying room air is fresh and discharges produced moisture content, it is necessary to a certain amount of fresh air of supplement, discharges considerable amount of useless
Gas.Existing fresh air supplements general room directly in heater box upper shed, is supplemented to heater box using workshop wind as fresh air, now follows
The relative humidity of ring wind is larger, and the time of surface of vehicle paint moisture evaporation is longer（Generally higher than ten minutes）, efficiency is low.
The content of the invention
For the problem that above-mentioned prior art is present, this utility model provides a kind of fresh air dehumidifying system, it is possible to decrease supplement
The humidity of fresh air, can also it is follow-up it is strong it is cold during cool-down dehumidification process is also carried out to sent room temperature wind, so as to accelerate vehicle body cover
The moisture content rate of volatilization on paint top layer, it is ensured that varnish spray painting work is normally carried out, it is ensured that paint film final mass.
To achieve these goals, a kind of fresh air dehumidifying system that this utility model is adopted, including finish paint sudden strain of a muscle dry chamber, finish paint
Dry turning transition chamber, area's heating system, two area's heating systems and strong SAPMAC method wind system are dodged, also including fresh air dehumidification device,
The fresh air dehumidification device includes casing, the filter being laid in casing, the electrically operated valve on casing and blower fan C,
Control electrically operated valve can be by the gas inlet box body in workshop, and filter can dehumidify to the gas for sucking, and blower fan C will be removed
Gas discharge Jing airducts after wet deliver to area's heating system, two area's heating systems carries out fresh air supplement；The strong SAPMAC method wind
The structure of system is identical with the structure of fresh air dehumidification device.
Preferably, pressure difference switch and pressure gauge on casing are also included.
Compared with prior art, the fresh air supplemented by this utility model after dehumidification treatments, the relative humidity of circulated air
Reduce by a relatively large margin, under identical drying temperature, the time of surface of vehicle paint moisture content volatilization shortens（Can typically shorten to 8 minutes with
It is interior）.Reduction in processing time means the reduction of occupation area of equipment, while required heating amount and air-supply air quantity are also simultaneously
Reduce, energy consumption is reduced up to 20%（Heat, air quantity can reduce 30%, and because increasing dehumidifying, therefore energy consumption increased）More than, reduce production
Cost, makes whole prebake process more low-carbon environment-friendly.Finally, the humidity of supplementary fresh air is reduced, can also be in follow-up strong cold process
In sent room temperature wind is also carried out cool-down dehumidification process, so as to accelerate the moisture content rate of volatilization on vehicle body finish paint top layer, it is ensured that varnish
Spray painting work is normally carried out, it is ensured that paint film final mass.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of dry turning transition chamber 2 of as shown in Figures 1 to 8, fresh air dehumidifying system, including finish paint sudden strain of a muscle dry chamber 1, finish paint sudden strain of a muscle,
One area's heating system 9, two area's heating systems 10 and strong SAPMAC method wind system 12, it is characterised in that also including fresh air dehumidification device
11, the fresh air dehumidification device includes casing, the filter 111 being laid in casing, the electrically operated valve 112 on casing
And blower fan C116, control electrically operated valve 112 can be by the gas inlet box body in workshop, and filter 111 can be to the gas of suction
Dehumidified, the gas discharge Jing airducts after dehumidifying are delivered to area's heating system 9, two area's heating systems 10 and carried out by blower fan C116
Fresh air is supplemented；The structure of the strong SAPMAC method wind system 12 is identical with the structure of fresh air dehumidification device 11.
Preferably, pressure difference switch 115 and pressure gauge 113 on casing are also included.
As shown in Fig. 2 main flow of the present utility model is：Fresh air dehumidification device will pass through blower fan C after the dehumidifying of workshop wind
It is sent in airduct, then fresh air supplement is carried out to the heating unit of area's heating system 9, two area's heating systems 10 by airduct, reduces
Relative humidity in two heating units, so as to ensure the dehydration rate of paint film after prebake.
Individually workshop wind is carried out cool-down dehumidification after filtration by fresh air dehumidifying system, and water capacity is dropped to 10-15g/kg,
And the wind after dehumidifying is sent to the fresh air supply port of heater box, strong cooling system similarly utilizes the principle, will be the wind after dehumidifying straight
Pick in strong cold house, it is ensured that the water content of paint film while strong cold effect, will not be increased.
Jing is tested, in preliminary drying stem portion using this programme reducing the humidity of the supplemented fresh air of prebake heater box, while
Being also adopted by this scheme reduces the relative humidity of the sent fresh air of strong cold air supplying and exhausting system, so as to ensure the same of the dehydration rate after prebake
When shorten the process time of prebake operation, save hall space and reach 170m, energy efficient improves Factory Building profit up to 200,000 Kcal
With energy consumption is saved while efficiency again.
From said structure, can be during prebake using this utility model, the fresh air that drying and warning is covered
The fresh wind of Jing dehumidifying is substituted for, so as to reduce mending the humidity of fresh air（General water capacity is less than 10 ~ 15g/kg）, and it is follow-up strong cold
During sent room temperature wind is also carried out cool-down dehumidification process, so as to accelerate the moisture content rate of volatilization on vehicle body finish paint top layer, it is ensured that
Varnish spray painting work is normally carried out, it is ensured that paint film final mass.
