Description

(54) DEVICE FOR CLEANING LIQUIDS

one

The invention relates to devices for cleaning liquids and can be used for cleaning impurities of water, mineral acids, organic liquids used in the electrical, electronic and chemical industries.

A device for purifying liquids by distillation is known, which includes an evaporator, a superheater with a nozzle, above which a refrigerator-condenser 1 is installed.

The disadvantages of the known device are limiting the range of cleaned liquids to a single object - water, insufficient purification from cations, easily volatile impurities and solid microparticles due to the use of a nozzle with a relatively small working surface, no drainage system and trapping of volatile impurities, insufficient effectiveness of the condenser during cleaning of liquids, prone to fogging, carrying out the process only at atmospheric pressure, as well as a possible change in the composition during cleaning their mixtures with different boiling points of the components due to the separate implementation of the evaporator and the superheater.

The purpose of the invention is to increase the degree of purification of liquids and preserve their composition.

The goal is achieved by distilling a device for cleaning liquids, including an evaporator, a superheater with a nozzle, over which a condenser / condenser is installed, provided with a nozzle installed in the lower part of the condenser-condenser, and a superheater and an evaporator are placed one above the other. in one case.

At the same time, the device is equipped with an insulating chamber separating the lower parts of the nozzle and the condenser cooler.

Moreover, it is advisable to fill the vaporizer with a nozzle.

Claims (3)

The device for cleaning liquids consists of an evaporator 1, a superheater 2, a DISTILLATION placed in one housing 3 and filled with a porous nozzle 4. Above the superheater there is a condenser cooler 5. Inside and outside the housing 3 there are heating elements 6 and 7 that correspond to the height of the evaporator 1 and steam superheater 2, between which adiabatic zone 8 is placed. Heating elements 6 and 7 are placed in housing 9 and provided with latches 10. Porous seal 11 is located on nozzle 4. Lower part of Cornus 3 provided with a pipe 12 for discharging the liquid to be cleaned, and its upper part with a nozzle 13 for discharging superheated steam connecting the housing 1 with the condenser cooler 5, in the lower part of which a nozzle 14 is located. In the condenser cooler 5 there is a nozzle 15 and confusors 16. The upper end of the nozzle 14 is located at the maximum cross section of the diffuser 15. Between the lower part of the nozzle 14 and the lower part of the 1-condenser 5 condenser 5 is an insulating chamber 17. The condenser-cooler 5 is equipped with a cool zhdayuschey rubaschkoy 18, nozzle 19 for discharging volatile impurities .m nozzles 20 for discharging purified liquid. The device works as follows. The source fluid through the pipe 12 enters the lower part of the evaporator 1, where the heating elements b are transferred to a dispersed vapor-liquid mixture passing through the adiabatic zone 8, which is designed to prevent sudden temperature fluctuations in the materials of the apparatus and the nozzle 4. From the adiabatic zone the stream passes into the steam superheating zone 2, heated by heating elements 7, where the main cleaning from less volatile impurities, for example cations, takes place. Superheated steam. containing volatile impurities, through the nozzle 14 enters the condenser-cooler 5, in the upper part of which, above the upper edge of the nozzle 14, the vapor condenses in the form of a thin film of liquid with simultaneous cleaning, if necessary, of volatile impurities, which are discharged through the nozzle 19 along the vacuum line mc in the capture system. The condensate flow film is cooled in the lower part of the condenser-cooler 5, located below the upper end of the nozzle 14, and removed from the apparatus through the nozzle 20. The invention provides for expanding the range of highly pure liquids, increasing the degree of purification of liquids from volatile organic and inorganic impurities not less than 10 times, from volatile impurities not less than 5 times compared with the known device. 1.
