Existing technology is that the direct discharge of the hot blast of microwave ventilation cooling system is outdoor, has caused the waste of heat, simultaneously because ventilation cooling system directly from the air draught of tobacco job shop, has influenced the humiture in workshop.
Because mostly the microwave ventilation cooling system be to require to set fan delivery according to the cooling of the highest temperature and magnetron, can not variable frequency adjustment, cause under the lower situation of winter or workshop temperature, air quantity is excessive, influences workshop moisture temperature, has strengthened the workshop air conditioning energy consumption.
Summary of the invention
A kind of microwave tobacco class process equipment UTILIZATION OF VESIDUAL HEAT IN equipment that the purpose of the utility model provides to existing problem in the above-mentioned prior art just; This equipment can effectively utilize microwave class tobacco processing equipment waste heat; Simultaneously also reduced of the influence of its ventilation cooling system, reduced tobacco job shop air conditioning energy consumption tobacco job shop humiture.
The purpose of the utility model realizes through following technical scheme: microwave tobacco class process equipment residual heat using device; Comprise microwave class firing equipment and the tobacco processing equipment that uses hot blast; Wherein: between the hot air inlet of the exhaust duct of microwave class firing equipment cooling system and tobacco processing equipment, be connected a hot blast conveying pipe road; The hot blast that microwave class process equipment is discharged is introduced tobacco processing equipment, and on the hot blast conveying pipe road, be connected with fresh wind tube road and volume damper.
In order to keep microwave class process equipment ventilation cooling system to the cooling effect of magnetron and make the hot blast wind-warm syndrome of discharge constant; On the exhaust duct of microwave class firing equipment cooling system, frequency conversion fan and temperature sensor are installed, temperature sensor is connected with fan frequency converter.
The said tobacco processing equipment of hot blast that uses is loosening and gaining moisture, hot blast leaves moisting, charger, roller drying, pneumatic conveying drying or pipe tobacco material wind selection equipment.
In order to make microwave class process equipment synchronous, on tobacco processing equipment hot blast conveying pipe road, connect exhaust duct and intake stack, and regulate air quantity through the magnetic valve that is installed on the pipeline with the air balance and the process time of the tobacco processing equipment that uses hot blast.When a plurality of tobacco processing equipments are produced simultaneously, when the air quantity that microwave processing equipment is discharged can not satisfy tobacco processing equipment air intake air quantity and requires, close exhaust duct emptying valve, open the new air valve in fresh wind tube road to satisfy the requirement of tobacco processing equipment air intake air quantity.
The utility model has the advantages that:
1, the waste heat that has effectively utilized microwave class tobacco firing equipment magnetron cooling system to produce has improved microwave class tobacco processing equipment capacity usage ratio.
2, reduce the new intake of tobacco processing equipment that uses hot blast, thereby reduced influence, reduced tobacco job shop air conditioning energy consumption tobacco job shop humiture.
3, can be constant about 70 ℃ through the hot blast wind-warm syndrome that fan frequency converter is discharged cooling system, reduce microwave class tobacco processing equipment ventilation cooling system exhaust air rate, reduced equipment energy consumption.
