Description
[technical field]
The utility model relates to a kind of air cleaning system, particularly air cleaning system between the PET hot filling.
[background technology]
Purification between the PET hot filling requires: whole 1000 grades or 10000 grades, and local laminar flow, indoor malleation; The temperature remains within the normal range for personnel's operation interval.
As shown in Figure 1, air cleaning system has only a low temperature drying wind supply air system between traditional large-scale PET hot filling, specifically be between hot filling and 100 grades of laminar flow hood are established at the top of corresponding hot filling machine main part, the both sides of these hundred grades of laminar flow hood are established an air outlet more respectively, these hundred grades of laminar flow hood and two air outlets are connected with the low temperature drying wind air-supply unit that is located at outside between hot filling, send low temperature drying air (among the figure with the solid arrow symbolic representation) with thermotropism bottling department part, and inner both sides are provided with return air inlet between hot filling, adopt side direction to arrive the return air inlet mode again through personnel's operation interval.This scheme can satisfy the air cleaning class requirement when static state, but has some problems dynamically the time, is mainly reflected in following three aspects: the one, and hot filling machine main body top hazes easily, falls under water, and water droplet drops in the bottleneck, easily causes product rotten; The 2nd, bottling department humidity is relatively large, and the lasting long trend that is arranged, and working space has fog, and it is tired out that the staff is sweat easily, influences work; The 3rd, operating ambient temperature and humidity are all higher, very easily form mould and grow.Cause the main cause of this problem to be:
1, hot filling machine main part constantly produces hot and humid steam, usually the moist steam temperature is at 70 ℃～80 ℃, hot humid air up flow naturally (among the figure with the dotted arrow symbolic representation), mix mutually with the low temperature drying air of blowing down from hundred grades of laminar flow hood (being generally 25 ℃～28 ℃) convection current soon, because two bursts of gas flow temperatures differ and reach 42 ℃～55 ℃, cold and hot crossing swords forms little rainfall weather, as easy as rolling off a log undergoing phase transition causes water vapour to tie mist, form the globule at last, and a lot of globules fall in conjunction with forming water droplet.
2, form the convection current collision because the low temperature drying direction of air that the hot and humid steam that the hot filling machine produces and hundred grades of laminar flow hood are sent is opposite, air-flow certainly will be toward flowing on every side, the part air-flow arrives top between hot filling, and in this process, further on furred ceiling or metope, condense at last with the cold air heat exchange and form more globules, the globule falls in conjunction with forming water droplet again.All the other air-flows with the purification cold wind at top around the hot filling machine inside flow through personnel's operation interval flow to around return air inlet, and in this process further cooling haze, the temperature between hot filling is constantly increased, it is uncomfortable that personnel's operation is inside easily felt.
