Abstract
The utility model discloses an apparatus for treating sewage by low-temperature vacuum evaporation, which comprises a reactor, a condenser, a vacuum pump, a freezing machine and refrigeration accessories of the freezing machine. The heat of sewerage treated in the reactor is vaporized in the state of vacuum after dispersed by the freezing machine, and the heat of water vapor is absorbed and coagulated into water by a cryogen in the condenser for drainage or reclamation. The concentration of the sewerage in the reactor is increased after vaporization, and the sewerage can be reclaimed and reused. The apparatus can be used for treating the sewerage without the need of chemical agents, a chemical agent system does not need to be added, the process of sewage treatment and the apparatuses are simplified, heat is reclaimed, water is saved, pollutant discharge cost and operation management cost are saved, and the occupation area of the apparatus is reduced.
Description
The utility model discloses a kind of device, be applicable to and handle or concentrated various waste liquids to have the three big functions that reclaim water, reclaim resource, concentrating spent liquor with cryogenic vacuum evaporation process sewage.
In the prior art, the dispose of sewage method of waste liquid, mainly be that chemical agent (medicament) is put in the processed sewage waste liquor, discharge through post precipitation again through reaction (have need stir), its weak point is that the total system various kinds of equipment is many, floor space is big, the operational management more complicated more can not reclaim resource (all kinds of expensive golden room).
The purpose of this utility model is to utilize the cryogenic vacuum evaporating principle, at the deficiencies in the prior art, makes a kind of waste disposal plant of the continuous operation of being made up of the low temperature closed circulation refrigeration system of vacuum vaporation system and refrigerant vapour-liquid alternation.
The purpose of this utility model is to realize in the following manner: the device of the cryogenic vacuum evaporation process sewage of being made up of reactor (2), scatterer (3), condenser (4), cooling coil (5), steam separator (6), cool condensation tank (8), refrigerator (9), heating calancria (10) between sump (1) and vacuum pump (7) and whole process is moved continuously by the co-ordinate motion of relevant portions such as power supply, button, connecting tube, valve, liquidometer.
The utility model compared with prior art has following advantage:
One, energy-conservation, directly reclaim the heat of refrigerator;
Two, water saving, the water contamination-free that evaporates can be recycled;
Three, do not add chemical agent, do not produce mud;
Four, littler than adding chemical agent method floor space;
Five, can work after the energising, easy to operate.
