Description
Technical field
The present invention relates to drying plant technical field, the high-temp waste gas waste heat on especially a kind of drying plant being applied to generation high temperature poisonous fume and coating material retracting device.
Background technology
Drying plant carries out heating, drying by high temperature air to base material, and its operating temperature sometimes can up to 200 DEG C, and equipment also needs constantly to supplement fresh air at work, and discharge section high-temp waste gas, the EGT of discharge is usually also more than 100 DEG C.The coating material of some base material contains noxious material, mixes in the offgas after high-temperature gasification, if these waste gas are directly discharged in air, and not only contaminated environment but also cause the waste of the energy and coating material.
Way of the prior art has two kinds: one to be directly be discharged in air by waste gas.Two is to be processed into by poisonous fume by exhaust treatment system nontoxic to be discharged in air again.First method is completely infeasible in current stage.Second method has high input, and causes the waste of the energy and coating material.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of high-temp waste gas waste heat rational in infrastructure and coating material retracting device, thus effectively solve high pollution, high investment, the energy and coating material waste problem.
The technical solution adopted in the present invention is as follows:
A kind of high-temp waste gas waste heat and coating material retracting device, comprise finned cooler, its input connects high-temp waste gas entrance by pipeline, the output of described finned cooler is divided into two-way, lead up to pipeline connecting fan, the output of described blower fan connects waste gas recovery drying plant entrance and substrate coating material absorbing device entrance respectively by pipeline; Pipeline of separately leading up to connects two road condensers, the output of described two road condensers connects fluid reservoir and centrifugal pump successively by pipeline, described centrifugal delivery side of pump connects coating material holder, described two condenser rear ends, road are connected demister, and the output of described demister is connected with finned cooler by pipeline.
Further improvement as technique scheme:
The output of described finned cooler is connected in parallel to two blower fans by pipeline;
Connecting line between described waste gas recovery drying plant entrance and substrate coating material absorbing device entrance is provided with Pneumatic gate valve;
Described two road condensers are separately installed with import and the outlet of chilled water.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, rationally, convenient and reliable operation.While high-temp waste gas waste heat recovery, condensation can reclaim substrate coating material, can reach twice laid, the effect of energy-saving and emission-reduction, structure is simple, less investment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, waste gas recovery drying plant entrance; 2, substrate coating material absorbing device entrance; 3, Pneumatic gate valve; 4, blower fan; 5, fluid reservoir; 6, centrifugal pump; 7, demister; 8, two road condensers; 9, finned cooler; 10, high-temp waste gas entrance.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the high-temp waste gas waste heat of the present embodiment and coating material retracting device, comprise finned cooler 9, its input connects high-temp waste gas entrance 10 by pipeline, the output of finned cooler 9 is divided into two-way, lead up to pipeline connecting fan 4, the output of blower fan 4 connects waste gas recovery drying plant entrance 1 and substrate coating material absorbing device entrance 2 respectively by pipeline; Pipeline of separately leading up to connects two road condensers 8, the output of two road condensers 8 connects fluid reservoir 5 and centrifugal pump 6 successively by pipeline, the output of centrifugal pump 6 connects coating material holder, two road condenser 8 rear ends are connected demister 7, and the output of demister 7 is connected with finned cooler 9 by pipeline.
The output of finned cooler 9 is connected in parallel to two blower fans 4 by pipeline.
Connecting line between waste gas recovery drying plant entrance 1 and substrate coating material absorbing device entrance 2 is provided with Pneumatic gate valve 3.
Two road condensers 8 are separately installed with import and the outlet of chilled water.
As shown in Figure 1, from high-temp waste gas (the substrate coating material containing volatilization that drying plant is discharged, temperature is 105 degrees Celsius) first through a finned cooler 9, (temperature slightly declines, drop to 87.5 degrees Celsius), two-way is divided from finned cooler 9 gas out, one tunnel is drawn by blower fan 4 and is got back to drying plant, when waste gas coating material excessive concentration, Pneumatic gate valve 3 is closed, waste gas enters in substrate coating material absorbing device, when concentration reduces, Pneumatic gate valve 3 is opened, and waste gas comes back to drying plant; Two road condensers 8 of separately leading up to again are lowered the temperature and are made EGT reach the condensing temperature of substrate coating, be condensed into liquid, receive in fluid reservoir 5 by back of pipeline, when the liquid capacity in fluid reservoir 5 reaches certain value, centrifugal pump 6 works, coating material is pumped in coating material holder and recycles, simultaneously from two road condensers 8 waste gas out through the temperature that demister 7(now exports be 37 degrees Celsius) again get back in finned cooler 9 and recycle.The waste heat recovery of final formation high-temp waste gas and recycling of substrate coating material, solve the waste problem of the energy and coating material.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
