Abstract
The invention discloses a dual-mode pyrotechnic composition drying system. The dual-mode pyrotechnic composition drying system comprises a drying chamber, a draught fan, a heat exchanger and a dust removing pond. A working medium circulation pipeline is sequentially connected with a compressor, a condenser, a first auxiliary evaporator, a second auxiliary evaporator and a main evaporator. A system main air flue sequentially passes through the first auxiliary evaporator, a channel A of the heat exchanger, the condenser, a drying chamber air inlet, the drying chamber, a drying chamber air outlet, a channel B of the heat exchanger and the second auxiliary evaporator and finally communicates with the dust removing pond. An auxiliary air flue is arranged between the drying chamber air outlet and a condenser air inlet and provided with an air door capable of being opened and closed, and the auxiliary air flue communicates with the main air flue through the air door. According to the system, the high energy efficiency ratio and the high drying efficiency are still achieved on the basis that safety is ensured. Compared with a traditional straight-line type drying system, energy is saved by more than 60%, and the drying time is shortened by more than 1/3; and meanwhile switching between two modes is convenient, compatibility is good, and the equipment utilization rate is high.
Description
Technical field
The present invention relates to a kind of pyrotechnic composition drying system.
Background technology
In drying system, what the return air of hothouse was expelled directly out external environment is referred to as straight-line；The return air of hothouse through heating again or dehumidifying etc. process again return to hothouse be referred to as circulating.The shortcoming of straight-line is in that heat energy utilization is insufficient, and Energy Efficiency Ratio is relatively low, and drying efficiency is relatively low.Although circulating Energy Efficiency Ratio is higher, but when using in the pyrotechnic composition drying system of fireworks and firecrackers, because solvent (such as the ethanol) volatilization gas etc. in pyrotechnic composition dust, pyrotechnic composition can not be got rid of completely, iterative cycles accumulation in air channel, concentration increases, and causes potential safety hazard.
Summary of the invention
In order to solve above-mentioned drawback, the technical problem to be solved is to provide a kind of drying system for pyrotechnic composition, is guaranteeing to have on safe basis higher Energy Efficiency Ratio.In order to solve above-mentioned technical problem, the technical solution used in the present invention is, a kind of double mode pyrotechnic composition drying system, including hothouse and main evaporator, condenser, compressor, blower fan, it is characterized in that, also include the first secondary vaporizer, the second secondary vaporizer, heat exchanger, dedusting pond；Working medium circulation pipeline sequentially connects compressor, condenser, the first secondary vaporizer, the second secondary vaporizer, main evaporator；
This system arranges main air duct and secondary air channel, wherein:
Main air duct is sequentially by the first secondary vaporizer, the A channel of heat exchanger, condenser, hothouse air inlet, hothouse, hothouse air outlet, the channel B of heat exchanger, the second secondary vaporizer, finally connection dedusting pond；
Secondary air channel is arranged between hothouse air outlet and condenser air inlet, and secondary air channel is provided with air door to be opened/closed, and secondary air channel connects main air duct by air door.
Adopt technique scheme, achieve the switching in both of which by the mode of disconnected, the logical action in secondary air channel.During described air door closed mode, in system, air flows along main air duct, and system is in line pattern.
During air door open mode, system is in circulation and dehumidifying pattern: in system, air major part circulates between hothouse and condenser, the return air fraction of hothouse air outlet sequentially enters dedusting pond through the channel B of heat exchanger, the second secondary vaporizer, constitutes dehumidifying passage；System is by dehumidifying passage air-out, and supplementary new wind sequentially enters condenser through the A channel of the first secondary vaporizer, heat exchanger.
Owing to, in the initial time period dried, the concentration of solvent volatility gas is higher；In the processing completion time used for them dried, medicine just has the dust of higher concentration when soon drying.Characteristic in drying course, according to material, it is possible to select to open in line pattern within the above-mentioned two period, it is ensured that safety.Circulation and dehumidifying pattern can be selected, to improve Energy Efficiency Ratio and drying efficiency in other periods.
Meanwhile, in both modes, extraneous new wind has carried out dehumidifying dust removal process by the first secondary vaporizer, is conducive to the raising of pyrotechnic composition drying efficiency and drying quality；Outside hothouse, the hot blast of row is sequentially by the secondary vaporizer of heat exchanger and second, and waste heat reclaims through two-stage, and the heat energy of different orders is obtained for and makes full use of.
And, the air of outer row eventually enters into dedusting pond, and environment will not cause dust pollution and potential safety hazard thereof.
In summary, the beneficial effects of the present invention is, guaranteeing still to have on safe basis higher Energy Efficiency Ratio and drying efficiency, compare with tradition straight-line drying system: energy-conservation more than 60%, drying time shortens more than 1/3；Easy switching between both of which, compatible good simultaneously, and utilization rate of equipment and installations is high.
Preferably, described air door is self closing door, and system is provided with dust concentration tester and escaping gas tester, the system opening and closing according to the Data Control self closing door of tester.Realize system fully automatic operation.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
