Description

technical field [0001] The invention relates to the technical field of pharmaceutical auxiliary equipment, in particular to a high-energy-saving hot-pressed water distiller. Background technique [0002] At present, there are two types of hot-pressed distilled water machines produced at home and abroad, one is a vertical evaporator type, and the other is a horizontal evaporator type. ), convert electric energy into heat energy for evaporation operation, only feed water is heated by working steam. Although the energy-saving effect is the best in the special equipment for producing distilled water at present, the following problems still exist: [0003] One is that the condensed water generated by the working steam contains a lot of heat, which is not recycled effectively, but thrown away in vain. The wasted heat can be seen from the following description: [0004] Taking a hot-press distilled water machine with a production capacity of 10 tons as an example, to produce 10,0...

Problems solved by technology

[0010] Second, heat recovery is more difficult: Although everyone knows that there is a large heat loss, there are many difficulties in recovering the above-mentioned heat. The main reasons are:

The above reasons may be that the hot-pressed water distillers at home and abroad have not been able to recover the heat of the working steam condensate so far.

[0014] The third is that the working efficiency of the hot press is reduced: due to the structure of the traditional demister (steam-water separator), the pure steam outlet of the evaporator (at the top of the evaporator) is too high, so that the pure steam of the evaporator The connecting pipeline between the outlet and the pure steam inlet of the hot press is too long (both are about 4m, especially the hot-pressed distilled water machine of the horizontal evaporator is longer, about 5m or more)

Because the pipeline of pure steam entering the hot press is long, the flow resistance of pure steam increases, which increases the suction force of the hot press, but the compression work of the hot press decreases accordingly, resulting in The power consumption of the heat press machine under the capacity increases, which is a waste of energy
