Description

MVR vapo(u)rization system

Technical field

The utility model relates to a kind of MVR vapo(u)rization system.

Background technology

Traditional evaporimeter is as low in single-action or multi-effect evaporator exist the thermal efficiency, power consumption is large, operating cost is high, some row such as waste resource are not enough, but also can produce carbon dioxide, the pernicious gases such as sulfur dioxide, bring a lot of adverse influences to social economy and human development, in addition, MVR system evaporation operating mode is easy to be subject to fluctuate such as feeding temperature, small sample perturbations such as condensed water level variation and departing from of heating cycle occurs, affect it and accurately controlled applying in the evaporation technology process of operating mode at needs, especially at accurate chemical field, as the industry preparation of nanometer silver nitrate, the industrial evaporation of sodium peroxydisulfate etc.

Summary of the invention

In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide and a kind ofly can reuses indirect steam and MVR vapo(u)rization system that can regulating system pressure ratio.

For this reason, the MVR vapo(u)rization system that the utility model provides comprises feed pump, preheating device, condensate pump, condensate draining, condenser, compressor, Matter Transfer pump, evaporimeter and discharging pump, described feed pump is connected with the first entrance of condenser through the first outlet of preheating device, described condensate pump is connected with the first entrance of evaporimeter through the first outlet of condensate draining, the outlet of described condenser is connected with the second entrance of evaporimeter through Matter Transfer pump, the first outlet of described evaporimeter is connected with discharging pump, described compressor is located between condenser and evaporimeter and respectively and is connected with the second entrance of condenser and the second outlet of evaporimeter.

The utility model has the advantages that: the indirect steam that 1, can produce MVR vapo(u)rization system reuses; 2, compressor adopts high temperature water spray and two kinds of water spray modes of low temperature water spray, has regulated water-spraying evaporation amount in the utilization that has ensured condensation water residual heat, regulates thus the actual pressure ratio of compressor, reaches and regulates MVR system pressure ratio object.

Brief description of the drawings

The structural representation of the MVR vapo(u)rization system that Fig. 1 provides for the utility model.

Detailed description of the invention

As shown in Figure 1, the MVR vapo(u)rization system that the utility model provides comprises feed pump 1, preheating device 2, condensate pump 3, condensate draining 4, condenser 5, compressor 6, Matter Transfer pump 7, evaporimeter 8 and discharging pump 9, described feed pump 1 is connected with the first entrance 51 of condenser 5 through the first outlet 21 of preheating device 2, described condensate pump 3 is connected with the first entrance 81 of evaporimeter 8 through the first outlet 41 of condensate draining 4, the outlet 52 of described condenser 5 is connected with the second entrance 82 of evaporimeter 8 through Matter Transfer pump 7, the first outlet 83 of described evaporimeter 8 is connected with discharging pump 9, described compressor 6 is located between condenser 5 and evaporimeter 8 and respectively and is connected with the second entrance 53 of condenser 5 and the second outlet 84 of evaporimeter 8, preheating device 2 is provided with the second outlet 22 and low-temp. spraying water pump 10 is passed through in the second outlet 22 successively, the first valve 11 is connected with compressor 6, the second outlet 42 of condensate draining 4 is successively through high-temperature water pump 12, the second valve 13 is connected with compressor 6.

In the present embodiment, when the 8 vapour-liquid temperature difference of evaporimeter in system excessive, illustrative system pressure ratio is excessive, depart from normal pressure ratio, now open the low-temp. spraying water yield that the first valve 11 strengthens compressor 6, the energy that compressor 6 is injected is mainly used in eliminating the degree of supercooling of water spray, and only there is a small amount of water-spraying evaporation, even there is the condensation of part indirect steam, due to compressor 6 exhaust end of a period constancies of volume, but the minimizing of water vapour quality, compression process is insufficient, pressure ratio is less than theoretical pressure ratio, reaches the effect that reduces pressure ratio.Otherwise, in the time that system pressure ratio is too small, open the high temperature injection flow rate of the second valve increase compressor 6, the energy that compressor 6 is injected is mainly used in making water-spraying evaporation, produces more water-spraying evaporation steam, and pressure ratio is greater than theoretical pressure ratio, reaches the effect that improves pressure ratio.
