Abstract
Description
Technical field
The utility model relates to a kind of evaporation equipment, particularly, is a kind of indirect steam recompression vapo(u)rization system.
Background technology
Be used for industries such as medicine, chemical industry, food, beverage, metallurgy, the energy, desalinization at present and carry out the vapo(u)rization system of liquid concentration, generally include at least one evaporimeter and gas-liquid separation device, the material that needs evaporation and concentration enters in the evaporimeter by the inlet of evaporimeter, heats concentrated by continue the input water vapour in heating interlayer to the material in the evaporimeter.In existing vapo(u)rization system, the indirect steam that evaporimeter is heated after concentrating normally directly discharges; Perhaps by cooling water with the indirect steam condensation, the cooling of cooling water and carry and also to need more energy.In fact, the indirect steam that evaporimeter is heated after concentrating also has higher enthalpy, particularly indirect steam is during becoming liquid condensation process from gaseous state, to discharge lot of energy, and above-mentioned dual mode does not all effectively utilize remaining heat energy in the indirect steam, causes a large amount of wastes of the energy.
Existing machinery formula steam recompression system is that indirect steam is directly compressed.Because the proportion very little (specific volume is very big) of the water vapour under the water vapour, particularly vacuum, volume flow is huge, and the difficulty of compression is very big.Usually the saturated-steam temperature of single stage compress only has 6-8 degree centigrade.The evaporation and concentration that can not be used for the higher material of the elevation of boiling point; Even the multi-stage compression saturation temperature promotes also about 15 degrees centigrade.So the scope of its application has great limitation.Heat energy steam recompression system also the saturated-steam temperature that sucks steam can only be improved below 20 degrees centigrade, and this method still will consume steam.Now, the application along with clean energy resourcies such as wind energy, water power, nuclear power, solar energy is utilizing system of the present invention, can realize the no emission of carbon-dioxide of evaporating concentration process.This will improve the greenhouse effects that are on the rise greatly.
The utility model content
Technical problem to be solved in the utility model provides a kind of indirect steam recompression vapo(u)rization system, and this equipment can heat that remaining heat energy effectively utilizes in the indirect steam after concentrating to evaporimeter, saves a large amount of energy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: indirect steam recompression vapo(u)rization system, comprise evaporimeter, condenser, heating agent compressor, and described evaporimeter comprises evaporation equipment and the gas-liquid separator that is connected with evaporation equipment; Described condenser has evaporation side and condensation side, wherein condensation side has steam inlet and condensate outlet, the steam (vapor) outlet of gas-liquid separator is connected by pipeline in steam inlet and the evaporimeter, evaporation side has heating agent import and heating agent outlet, heating agent outlet is connected by the pipeline and the heat medium import of heating agent compressor, evaporimeter, and the heating agent outlet exports connection by the heat medium of pipeline and evaporimeter.
The evaporimeter of this programme both can be that single effect evaporator also can be a multi-effect evaporator, its form can be any board-like, tubular type or the other forms of evaporimeter that rises film, falling liquid film, lifting film or heating flash evaporation formula, it can be the single effect evaporation system that a cover is formed, and also can or overlap two effect or the multiple effect systems that evaporimeter is formed by two covers more.After the material that need to concentrate enters in the evaporimeter of vapo(u)rization system, concentrate through an effect or multiple-effect evaporation, the indirect steam of afterbody by condenser with the thermal energy conduction of indirect steam to heating agent, liquid heating agent evaporates in condenser and with the indirect steam condensation, the compressed machine compression of gaseous state heating agent after the evaporation makes it reach required pressure, carrying out the heat medium import of evaporimeter again heats the material in the evaporimeter, under higher pressure, be condensed and make material evaporation, get back to condenser after the heating agent decompression of condensation afterwards, with the indirect steam transducing after under certain pressure, evaporate, carry out the waste heat in the recycling indirect steam.This programme does not directly compress indirect steam by existing machinery formula steam recompression (MVR) system, but a large amount of energy absorption of emitting during with the indirect steam condensation by the heating agent that is easier to compress, and make liquid heating agent change the heating agent of gaseous state into, after this heating agent compression, its saturated-steam temperature can promote 150 ℃, promptly can be used as the heat medium of evaporimeter.Like this, the indirect steam that the big energy that produces in the evaporimeter is very big will be attained the Way and be utilized fully.
Described evaporimeter is single effect evaporator or multi-effect evaporator.
The material inlet of described evaporimeter is connected by pipeline and material preheater.When feeding temperature is low,, can before system's operation, use a preheater to improve the feeding temperature of material for reaching the evaporability of design fast.
The proportion of proportion when described steam is in saturated vapor pressure when heating agent is in saturated vapor pressure under the equality of temperature.This programme is introduced ' heating agent ' that is easy to compress and is replaced directly steam being compressed, and improves its saturated-steam temperature when improving pressure, and then can be used as the heat medium of evaporimeter.Heating agent can be selected various types of freon or allied substances for use.
Described steam (vapor) outlet is connected by pipeline and vavuum pump, and the pipeline between steam (vapor) outlet and the vavuum pump is also connected with the condensate discharge pipeline.The noncondensing gas of material side is extracted out by vavuum pump.
To sum up, the beneficial effects of the utility model are: a large amount of energy absorption that the utility model is emitted during with the indirect steam condensation by the heating agent that is easier to compress, and make liquid heating agent change the heating agent of gaseous state into, after this heating agent compression, its saturated-steam temperature can promote 150 ℃, promptly can be used as the heat medium of evaporimeter.Like this, the indirect steam that the big energy that produces in the evaporimeter is very big will be attained the Way and be utilized fully.
