Abstract
The utility model discloses a condensate water drainage system applied to a mechanical vapor recompression (MVR) evaporator. The MVR evaporator comprises a mechanical compression fan and a vacuum-pumping system, and comprises a condensate storage tank, wherein three condensate water intake pipelines are arranged on the top of the condensate storage tank and respectively connected with a water collecting hopper in front of the inlet of the mechanical compression fan, a condensate water discharge hole at the bottom end inside a volute of the mechanical compression fan, and a mechanical compression fan outlet; a vacuum discharge pipeline and a vacuum-pumping pipeline are additionally arranged on the top of the condensate storage tank and connected with the vacuum-pumping system; a condensate water discharge pipeline is arranged at the bottom end of the condensate storage tank; normally open electromagnetic valves are arranged on the three condensate water intake pipelines; normally closed electromagnetic valves are arranged on the vacuum discharge pipeline; the normally closed electromagnetic valves are arranged on the vacuum-pumping pipeline; the normally closed electromagnetic valves are arranged on the condensate water discharge pipeline. The condensate water drainage system is high in automatic degree, the amount of labor of a worker is reduced, the efficiency of labor is improved, and the operation efficiency is greatly reduced.
Description
Technical field
The utility model belongs to new forms of energy and energy-efficient-industrial energy saving field, is specifically related to a kind of for the concentrated MVR evaporimeter condensate water discharging system of solution.
Background technology
MVR evaporimeter is a kind of energy-efficient evaporation concentration equipment, be a kind of with electric energy replace steam as evaporation thermal source equipment.It has introduced mechanical compress blower fan part than conventional evaporator more, however operating cost will be well below direct use steam the multiple-effect evaporation unit as thermal source.MVR evaporimeter only need use the thermal source of a small amount of raw steam as heater in the time of start operation, in evaporimeter, the heated vaporization generation of solution indirect steam is inhaled in mechanical compress blower fan and is added into saturated indirect steam by the mechanical energy energy of impeller, temperature and pressure has all obtained certain lifting, jet chimney again, the saturated vapor that obtains temperature rise turns back to the thermal source of heating clamber as heating clamber heating, complete after a circulation, just can stop as the raw steam that starts thermal source, whole system is almost not need to use raw steam.Double evaporation-cooling part in the time that pipeline is inhaled into blower fan is condensed into condensed water, the indirect steam entering in volute of blower also can produce a part of condensed water in compression temperature-rise period, and the steam of compression after heating up reenters evaporimeter by pipeline and has few steam-condensation and produce condensed water in tube wall flows into blower fan, if this three partial condensations water is processed the dynamic balancing that affects impeller not in time, also affect the stability of whole fan operation.The at present domestic method of directly discharging with pump that this two parts condensed water is generally taked, automaticity is low, and the operate power of pump is high, and cost is larger.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned deficiency, and a kind of condensate water discharging system and control method thereof for MVR evaporimeter is provided.
Key problem in technology of the present utility model is to adopt the condensation storage tank of a certain volume capacity as the carrier of condensed water, and by being set, pipeline and MVR evaporimeter organically combine, its concrete technical scheme is: a kind of condensate water discharging system, described drainage system is for MVR evaporimeter, described MVR evaporimeter comprises mechanical compress blower fan and pumped vacuum systems, it is characterized in that comprising condensation storage tank, described condensation tank top is provided with three condensed water inlet channels and connects respectively the drip pan before mechanical compression fan import, the condensed water discharge outlet of mechanical compress volute of blower inner bottom and mechanical compress fan outlet, described condensation tank top is separately provided with a vacuum pumping pipeline and a vacuum lead connects pumped vacuum systems, described condensation storage tank bottom is provided with condensed water discharge pipe road, on described three condensed water inlet channels, be provided with normally open solenoid valve, on described vacuum pumping pipeline, be provided with normally closed solenoid valve, on described vacuum lead, be provided with normally closed solenoid valve, described condensed water discharge pipe road is provided with normally closed solenoid valve.Described drainage system connects DCS Distributed Control System.
A kind of condensate water discharging system control method, comprise the following steps: first when DCS system shows that in condensation storage tank, condensed water reaches discharge water level, system is sent instruction all closes three normally open solenoid valves on condensed water inlet channel, normally closed solenoid valve on vacuum pumping pipeline is opened and is made vacuum evacuates, then the normally closed solenoid valve on condensed water discharge pipe road is opened emptying condensed water, the emptying rear system of condensed water is sent instruction closes the normally closed solenoid valve on condensed water discharge pipe road, then the normally closed solenoid valve on vacuum lead is opened condensation storage tank is vacuumized, in the time that the vacuum of vacuum in condensation storage tank and the pumped vacuum systems of MVR evaporimeter is identical, normally closed solenoid valve on vacuum lead is closed, three normally open solenoid valves on last condensed water inlet channel are all opened and are allowed condensed water enter condensation storage tank, circulating is exercised intrasystem condensed water discharge like this.
The beneficial effects of the utility model: the utility model is by keeping same vacuum by condensation storage tank and MVR evaporimeter, make it be combined into unified entirety, then utilize the opening and closing of DCS Distributed Control System control magnetic valve, reach the object of automatic control, its automaticity is high, reduce workman's amount of labour, raise labour efficiency, and greatly reduce the power of operation.
