Technical field
The utility model is related to a kind of MVR vaporising devices, particularly discloses the MVR vaporising devices that a kind of normal temperature starts.
Background technology
It is a kind of processing effective means of wastewater from chemical industry with MVR evaporating waste waters due to the demand of disposal of waste gas, water and industrial residue, and it is a lot
Small enterprise's discharge capacity requires that MVR evaporations system could be entered by being preheated to boiling point in conventional MVR evaporations again per hour less than one ton
System, system could normally be run.Material must be preheated for this, and such as Electroplate Factory of some factories, Treatment of Metal Surface factory etc.,
There can not possibly be boiler, discharge capacity is again little, it is impossible to use steam preheating, if using electrical heating, price is no doubt one side, and more
What is solved is that the most corrosivity of material is very strong, and corrosion resistance is difficult to solve electrical heating elements at high temperature, and because heated
Material does not flow substantially in journey, heat transfer efficiency extreme difference.The phenomenon of coking fouling is easily produced on heating element heater wall.
MVR vaporising devices conventional at present are generally using two sections of preheatings, such as Fig. 1, plant running for a period of time after, waste water
First condensed water preheater 1, is preheated using the heat of the condensed water of evaporator heater 3 during normal operation to material.
When MVR vaporising devices are introduced into normal operation, evaporator heating chamber 3 is because of no condensed water, it is impossible to which material is preheated, at this moment
Elder generation is accomplished by after waste water enters vapor preheater 5, material is heated to boiling point by steam, then starts compressor 4, material enters
Enter evaporator 2, heated and produced after condensed water by evaporator heating chamber 3, condensed water enters to be entered in condensation water preheater 1 to material
Row heating.That is, device is when bringing into operation, it is necessary to which crossing makes steam make after material reaches boiling point, then open compressor,
Whole device could run well, and otherwise starting compressor 4 while device starts just can not be such that device normally runs, and this is just
Cause energy consumption too high, cost increase.
The content of the invention

The condensing water inlet 102 that the 4th temperature control valve 9 is crossed with the condensation water preheater 1 is connected.
First temperature control valve 6, second temperature control valve 7, the 3rd temperature control valve 8,9 points of the 4th temperature control valve
Wei not temp autocontrolled valve.
When 4 initial start of compressor, the temperature control valve 9 of second temperature control valve 7 and the 4th is closed, described
First temperature control valve 6 and the 3rd temperature control valve 8 are opened；When the second temperature control valve 7, the 3rd temperature control valve 8 are examined
When measuring the temperature of charge in evaporator 2 and rising to boiling temperature, the temperature control valve 8 of the first temperature control valve 6 and the 3rd
Close, the temperature control valve 9 of second temperature control valve 7 and the 4th is opened.
The beneficial effects of the utility model are：Starting compressor 4 at the very start, carried out without using steam or electrical heating pre-
Heat, and the compressed air heat heated material produced with 4 machines of compression.Controlled by first temperature control valve 6, second temperature
Valve 7, the 3rd temperature control valve 8, the wheel flow control of the 4th temperature control valve 9, before material reaches boiling temperature, the first temperature
The temperature control valve 8 of control valve 6 and the 3rd is opened, and the temperature control valve 9 of second temperature control valve 7 and the 4th is closed, and compressor 4 is continuous
