Description
Technical field
The present invention relates to a kind of pyrotechnic composition drying systems.
Background technology
In drying system, the return air of hothouse is expelled directly out the referred to as straight-line of external environment；The return air of hothouse passes through
It crosses the processing such as heating or dehumidifying again and again returns to the referred to as circulating of hothouse.The shortcomings that straight-line, is heat energy utilization not
Fully, efficiency is relatively low, and drying efficiency is relatively low.Although circulating efficiency is relatively high, dried in the pyrotechnic composition of fireworks and firecrackers
In use, because solvent (such as alcohol) volatilization gas in pyrotechnic composition dust, pyrotechnic composition cannot exclude completely, in wind in system
Iterative cycles accumulate in road, and concentration increases, and leads to security risk.
Invention content
In order to solve above-mentioned drawback, technical problem to be solved by the invention is to provide a kind of dry systems for pyrotechnic composition
System has higher Energy Efficiency Ratio on the basis of ensuring safety.In order to solve the above-mentioned technical problem, the technical side that the present invention uses
Case is a kind of double mode pyrotechnic composition drying system, including hothouse and main evaporator, condenser, compressor, wind turbine, feature
It is, further includes the first secondary evaporator, the second secondary evaporator, heat exchanger, dedusting pond；Working medium circulation pipeline sequentially connects pressure
Contracting machine, condenser, the first secondary evaporator, the second secondary evaporator, main evaporator；
Main air duct and secondary air duct is arranged in the system, wherein：
Main air duct sequentially passes through the first secondary evaporator, the A channel of heat exchanger, condenser, hothouse air inlet, drying
Room, hothouse air outlet, the channel B of heat exchanger, the second secondary evaporator, are finally connected to dedusting pond；
Secondary air duct is set between hothouse air outlet and condenser air inlet, and secondary air duct is equipped with air door to be opened/closed, secondary
Air duct is connected to main air duct by air door.
Using above-mentioned technical proposal, the switching in both of which is realized by way of disconnected, the logical action in secondary air duct.
When the air door closed state, air is flowed along main air duct in system, and system is in line pattern.
When air door opening state, system is in cycle and hydrofuge pattern：Air is most of in hothouse and condensation in system
It is circulated between device, sequentially the channel B through heat exchanger, the second secondary evaporator enter the return air fraction of hothouse air outlet
Dedusting pond constitutes hydrofuge channel；Air is discharged by hydrofuge channel in system, and the fresh air of supplement is sequentially through the first secondary evaporator, heat
The A channel of exchanger enters condenser.
Since in the initial time period of drying, the concentration of solvent volatility gas is higher；In the processing completion time used for them of drying, drug
The dust of higher concentration is just had when soon drying.During the drying process, it according to the characteristic of material, can select in above-mentioned two
In line pattern is opened in period, it is ensured that safety.Cycle and hydrofuge pattern can be selected in other periods, to improve Energy Efficiency Ratio and do
Dry efficiency.
Meanwhile in both modes, extraneous fresh air has carried out dehumidifying dust removal process by the first secondary evaporator, is conducive to cigarette
The raising of gunpowder drying efficiency and drying quality；The hot wind arranged outside hothouse sequentially by heat exchanger and the second secondary evaporator,
Waste heat is recycled by two-stage, and the thermal energy of different orders, which is obtained for, to be made full use of.
Moreover, the air arranged outside eventually enters into dedusting pond, dust pollution and its security risk will not be caused to environment.
In summary, the beneficial effects of the present invention are, on the basis of ensuring safety still have higher Energy Efficiency Ratio and
Drying efficiency, compared with traditional straight-line drying system：Energy saving 60% or more, drying time shortens 1/3 or more；Two kinds of moulds simultaneously
Easy switching between formula, good compatibility, utilization rate of equipment and installations are high.
Preferably, the air door is self closing door, and system is equipped with dust concentration tester and escaping gas tester, is
System controls the opening and closing of self closing door according to the data of tester.Realization system fully automatic operation.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Description of the drawings
