Description
Technical field
The utility model relates to a kind of drying system of fireworks pyrotechnic medicine.
Background technology
In recent years in fireworks and firecrackers industry, heat pump drying technology is promoted to the whole industry gradually, improves production efficiency, decreases the loss brought because of Changes in weather, but existing heat pump drying technology generally also exists the problem of following two aspects:
1, heat utilization rate is not high, and energy consumption is still too large.Particularly temperature low time in winter, higher to the degree of dependence of the additional heat of electricity, cause larger impact to electrical network, particularly the fireworks and firecrackers manufacturing enterprise overwhelming majority is in rural area, and rural power is generally not enough, and impact is normally produced.On the other hand, the direct hydrofuge mode that existing drying room is taked, has also taken away partial heat energy while discharging moisture content; Simultaneously at high operating temperatures (as 60 DEG C or more), the hydrogenesis in air becomes the ability of aqueous water to reduce, and even disappears.
2, there is potential safety hazard.Winter, dry temperature was low, and need to use resistance auxiliary heating, lack the suppression treatment measures of dust in drying room, resistance assistor is arranged in drying room simultaneously, brought larger danger to pyrotechnic composition drying; In addition, direct hydrofuge releases the air of system not through dust removal process, carries part gunpowder dust and enters external environment condition, be not only unfavorable for environmental protection, also leave potential safety hazard.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, provides a kind of drying system being exclusively used in fireworks pyrotechnic medicine safely and efficiently.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of pyrotechnic composition drying system, comprises air source heat pump and drying room, and air source heat pump comprises the working medium circulation loop that working medium pipeline sequentially connects compressor, condenser, throttling arrangement, main evaporator are formed; Air inlet and the air outlet of drying room are communicated with the air outlet of condenser respectively and air inlet forms hydronic main air duct; Main air duct is provided with new wind and supplements passage and hydrofuge passage; It is characterized in that, between the throttling arrangement of described air source heat pump and main evaporator, be also provided with secondary evaporimeter; Described new wind supplements between passage and hydrofuge passage and is provided with heat exchanger; Damp-heat air in hydrofuge passage, sequentially by after described heat exchanger and secondary evaporimeter, enters main evaporator room; The air inlet of described drying room is arranged at drying room top, and the air outlet of drying room is arranged at drying room bottom, forms hot blast circulation style from top to bottom in drying room.
Adopt technique scheme, the damp-heat air in hydrofuge passage is sequentially through the process of three steps:
1. damp-heat air (about 60 DEG C) preheating when over-heat-exchanger enters the new wind of condenser, and reduce the energy promoting new air temperature and consume, damp-heat air own temperature reduces (about 40 DEG C) simultaneously.
2. then damp-heat air enters secondary evaporimeter again, and secondary evaporimeter absorbs the pre-hot working fluid of wherein heat, before working medium enters main evaporator, improve Temperature of Working, alleviates compressor load and reduces energy consumption; Damp-heat air own temperature reduces simultaneously; it includes hydrogenesis and becomes aqueous water to depart from (dehumidifying); take the gunpowder dust wrapped up in air in the process that aqueous water departs from and depart from (dedusting); while protection of the environment, eliminate in air the potential safety hazard that there is gunpowder dust and cause.
3. through the damp-heat air (about 20 DEG C) of above-mentioned process, continue to enter main evaporator room and surrounding air mixing, effectively can improve the operating ambient temperature of main evaporator, especially in the time (19 DEG C can be promoted to during environment temperature 8 DEG C) that environment temperature is lower, thus improve the condition of work of heat pump, reduce the additional heat of electricity and use and avoid frosting.
By above-mentioned three steps, for the temperature characterisitic of damp-heat air in different phase, be provided with corresponding heat energy utilization mode, constitute corresponding suitable level and utilize system, achieve fully effectively utilizing hydrofuge heat energy, greatly reduce heat energy loss, improve moisture exclusion efficiency.
The principle that tradition drying room rises based on hot-air, be all be designed to air inlet under, air outlet is in upper mode, but we find, for pyrotechnic composition drying room, this hot blast circulation style from bottom to top easily causes " airborne dust " phenomenon, makes the gunpowder dust in drying room ground and even material disc enter in circulated air, and trickle down at random in system air channel, form serious potential safety hazard.The utility model changes the top-down circulation style of hot blast into, can avoid above-mentioned " airborne dust " phenomenon, significantly reduce potential safety hazard.And the steam on material surface can be taken away in time, improve drying efficiency.
As from the foregoing, the beneficial effects of the utility model are, provide a kind of professional drying system being applicable to fireworks pyrotechnic medicine, have good security, energy saving and the feature of environmental protection.
With improvement, described system is provided with auxiliary heating subsystem, comprises the radiator of device in main air duct, and radiator is communicated with hot-water supply device by water circulating pipe and circulating pump.Drop into this auxiliary heating system where necessary, because electric device can away from ducting system, without any electric spark produce may, to stop potential safety hazard.
With improvement, described heat pump apparatus of air source cross valve.To realize changing between refrigeration mode and heating mode, after oven dry completes, systematic evaluation is refrigeration mode, pyrotechnic composition can be cooled without the need to shifting out drying room, not only increase production efficiency, reduce labour intensity, what is more important avoids the potential safety hazard of handling process, is conducive to fireworks medicine drying work standardization and carries out in order.
Preferably, the compressor flow of described main air duct is 2000 ~ 3500m
3/ h, blower press is 800 ~ 715Pa.The hot blast being conducive to entering drying room directly blows to suitable speed and pressure on the drying room wall on sealing opposite, then in drying room, form the soft hot air flow without dead angle, all materials are all heated evenly, dry progress is unified, degree of drying is corresponding, to improve the volume drying efficiency of material in drying room, " airborne dust " phenomenon is avoided to ensure safety.
In order to avoid the appearance of " airborne dust " phenomenon further, guarantee safety.Preferably, the air outlet of described drying room is greater than air inlet.Further, the area of described air outlet is 8 ~ 20 times of air-admitting surface.Especially 12 ~ 16 times.Preferably 14 ~ 15 times.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
