t, P
dCatalytic action under, organic exhaust gas can be oxidized burning generate harmless water and carbon dioxide.Can discharge a large amount of heat in catalysis, the combustion process, reaction back gas temperature can significantly be risen, these high-temperature gases are directly outdoor by smoke stack emission usually, both brought thermal pollution, caused the waste of energy again.
On the other hand, in the steel oven dry processing procedure, drying chamber need use fuel that it is heated, and temperature is reached about 70 ℃, with oven dry steel surface paint, in its heating process, needs to use a large amount of natural gases or electric energy, and its energy resource consumption is bigger.
In addition, in the steel preheating processing procedure, preheating chamber need use fuel that it is heated, and temperature is reached about 250 ℃, in its heating process, has a large amount of energy resource consumptions equally.
The utility model content
The utility model is intended to provide a kind of steel plate pretreatment device of energy-saving and environmental protection more, and it is used to dry steel plate with the hot gas that Catalytic Combustion of Organic Exhaust Gases produces, and has both reduced thermal pollution, has reduced the consumption of fuel again.
Steel plate pretreatment device of the present utility model, comprise feed mechanism, conveying mechanism, preheating device, derusting device, spray-painting plant, drying unit and discharging mechanism, it is characterized in that: it also includes the coating cloud treating apparatus, the catalytic bed that is provided with heater in the reative cell of coating cloud treating apparatus and places catalyst, and reative cell drives air by air pump and flows, its air inlet pipe road is communicated with the paint spray booth and the drying chamber of spray-painting plant, and its outlet pipe is communicated with the drying chamber of drying unit.
Organic exhaust gas in paint spray booth and the drying chamber is under air pump drives, can enter in the reative cell of coating cloud treating apparatus, when reaction chamber temperature is heated to the catalysis initiation temperature, organic exhaust gas can be in catalytic bed the effect of catalyst under oxidizing fire, discharge a large amount of heats, produce high-temperature gas, high-temperature gas is under air pump drives, and the drying chamber that flows to drying unit by outlet pipe is dried steel plate.The heat energy that it has made full use of the high-temperature gas that organic exhaust gas such as catalytic combustion coating cloud in the reative cell produces had both reduced hot driving, had reduced the fuel consumption that oven dry is handled, energy-saving and environmental protection again.
Description of drawings
The structural representation of a kind of steel plate pretreatment device of Fig. 1;
Fig. 2 is a kind of schematic diagram of steel plate pretreatment device.
The specific embodiment
A kind of steel plate pretreatment device, as Fig. 1, Fig. 2, comprise the rollgang 1 that is used to carry steel plate, steel plate is carried to the feed mechanism of roller-way, on the roller-way steel plate is carried out The pre-heat treatment, remove the preheating device 2 of surface and oil contaminant and moisture content, remove the derusting device 3 of surface of steel plate rusty stain, the spray-painting plant 4 that surface of steel plate is sprayed paint, with the drying unit 5 of surperficial paint drying, and discharging mechanism, it also includes coating cloud treating apparatus 6, the reative cell of described coating cloud treating apparatus is divided into two parts, the heating clamber and the catalytic combustor that catalytic bed is set of heater are set, heating clamber and catalytic combustor, front and back are communicated with successively.Be provided with heaters 61 commonly used and the catalytic bed 62 of placing catalyst such as electrical heating in the reative cell of coating cloud treating apparatus, the heater temperature in the reative cell that can raise, the admission line 7 of reative cell is communicated with the paint spray booth of spray-painting plant and the drying chamber of drying unit 5, its outlet pipe 8 is communicated with the drying chamber of drying unit, air pump or blower fan 9 are installed on the admission line of reative cell or the outlet pipe, again or air pump or blower fan 9 all be installed on admission line and the outlet pipe, air pump can go into to reative cell to flow into from air inlet pipe by steering current, with the organic exhaust gas sucting reaction chambers such as paint in paint spray booth and the drying chamber, air-flow in the air pump guiding reative cell flows to drying chamber from outlet pipe, thereby the high-temperature gas that will produce behind the reative cell exothermic catalytic reaction imports drying chamber oven dry steel plate.
Owing to need not damage the paint of surface of steel plate in the drying course, the temperature of oven dry need be controlled at about 70 ℃ usually, because the gas temperature of introducing from reative cell is very high, for fear of its destruction to the surface of steel plate enamelled coating, introducing fresh wind tube road with extraneous Cryogenic air also can be set in the drying chamber of drying unit, introduce the amount of air in fresh wind tube road and the amount of introducing the high-temperature gas of reative cell by control and can control temperature in the drying chamber.The gas flow of two pipelines can be passed through air pump, blower fan drives.
Reative cell leads in the outlet pipe of drying chamber can be provided with air door, and the aperture of air door is adjustable, goes into the amount of the high-temperature gas in the drying chamber by the damper controllable flow, thus the temperature of control drying chamber.
The outlet pipe 8 of reative cell also can be communicated with exhaust chimney by by-pass line 12, and it can be discharged by exhaust chimney when high temperature hot gas does not need or can't enter drying chamber, and control valve 13 is installed on the by-pass line, can regulate switching as the case may be.
The admission line 7 of reative cell and outlet pipe 8 are by the heat exchange each other of same heat exchanger 63, it can shift to an earlier date preheating to the coating cloud that enters reative cell, can reduce simultaneously the temperature of reative cell outlet hot gas, to a certain extent, can reduce reative cell and be heated to the required heat of catalysis ignition, thereby further reduce energy resource consumption.And because the restriction of bake out temperature, it is too high that its outlet temperature does not originally need, so the decline of outlet temperature can not bring adverse effect to oven dry.
In addition, reative cell also can be provided with the outlet pipe in the preheating chamber that leads to preheating device, and it can partly be incorporated into the high-temperature gas of reative cell catalytic combustion preheating chamber and carry out preheating, thereby also can reduce the energy that preheating consumes, further reduce the consumption of the energy, improve energy-conservation effect.
In addition, the preheating chamber 2 of preheating device also can have pipeline 10 to be communicated with drying chamber, and it can introduce drying chamber with high-temp waste gas after the preheating chamber preheating dries, and can further reduce the energy resource consumption of oven dry.Because does not handle on preheating chamber light plate surface, exist the possibility of magazines such as dust bigger in the waste gas after the preheating chamber preheating, enter drying chamber and be adsorbed on the paint of surface of steel plate for fear of the dust magazine, need to be provided with high-temperature filter 11 on the pipeline, the filtering of dust magazine.
