Embodiment 1

[0020] Embodiment 1, as shown in Figure 1, an air-cooled dry cleaning machine solvent recovery device, wherein the drying channel 1 and the distillation channel 2 are independent of each other, the two channels are respectively provided with a drying solvent cooling recovery device 5 and a distillation solvent Air-cooled heat exchangers 3 are respectively arranged in the circuits of the cooling recovery device 6 and the drying and distillation solvent cooling recovery devices 5 and 6 . When the device in this embodiment is used, since the distillation channel 2 is only communicated with the distillation cooling recovery device 6, the speed and efficiency of distillation cooling recovery solvent can be improved.

Embodiment 2

[0021] Embodiment 2, as shown in Figure 2, an air-cooled dry cleaning machine solvent recovery device, wherein the drying channel 1 and the distillation channel 2 are independent of each other, the two channels are respectively provided with a drying solvent cooling recovery device 5 and a distillation solvent An air-cooled heat exchanger 3 is provided after the cooling recovery device 6 and the circuits of the drying and solvent distillation cooling recovery devices 5 and 6 are connected. When the device in this embodiment is in use, because the distillation channel 2 is only communicated with the distillation solvent cooling recovery device 6, the speed and efficiency of the distillation cooling recovery solvent can be improved; The loops are connected to each other and share a set of air-cooled heat exchanger 3, therefore, its structure is more compact than that of Embodiment 1.

Embodiment 3

[0022] Embodiment 3, as shown in FIG. 3 , an air-cooled dry cleaning machine solvent recovery device, wherein the drying channel 1 and the distillation channel 2 are respectively connected with the cooling chamber 7, and a set of drying and distillation solvent is arranged in the cooling chamber 7. Cooling recovery device 8, air-cooled heat exchanger 3 is arranged in the circuit of drying distillation solvent cooling recovery device 8. In this embodiment, since the drying passage 1 and the distillation passage 2 communicate with the cooling chamber 7 and its drying and distillation solvent cooling recovery device 8, the structure is the most simple and practical, the solvent recovery efficiency is high, and the operation of the unit has been optimized.

[0023] As shown in Figure 4-6, that is, in Embodiments 4, 5, and 6, the heat exchangers described are all air-cooled heat exchangers 9, and the remaining structures correspond to the above-mentioned Embodiments 1, 2, and 3 resp...

Abstract

The wind cooled solvent recovering device for dry washing machine includes a stoving channel, a distilling channel and a cooling recovery unit connected together. The cooling recovery unit has wind cooled heat exchanger in the cooling recovery loop; and the distilling channel is provided with one medium type or one wind cooled heat exchanger. The present invention has high solvent recovering efficiency, low running cost, simple recovering device structure and other advantages.

Description

technical field [0001] The invention belongs to the field of washing machines and relates to a device for solvent drying and distillation recovery of an air-cooled dry cleaning machine. Background technique [0002] The washing solvent of the existing air-cooled dry-cleaning machine mainly adopts tetrachlorethylene, and the recovery of its solvent mainly involves the recovery of the drying solvent and the distillation of the distillation solvent. The heat content of the solvent vapor in the recovery process of the distillation solvent is the drying The solvent recovery process is twice as long, so the drying and distillation system is usually completed by two independent systems. Therefore, at present, the drying and distillation methods of air-cooled dry cleaning machines mainly include the following two methods: the first one is to separate the passages of drying and distillation solvents, each of which has a set of cooling recovery devices, and the circuits of the cooling...
