Specific implementation mode
In the utility model, evaporating column is commercially available.
The utility model is described in further detail with reference to the accompanying drawings of the specification：
Embodiment：
A kind of pigment waste acid concentrator, includes the preheater 1 being connect with spent acid input duct, and the pipe outlet of preheater 1 connects
It is connected to primary heater 2；The outlet of primary heater 2 is connected to the first evaporator 3 by pump, and the first evaporator 3 adds with two level
Hot device 4 is connected by pipeline, and pipeline is equipped with pressure reducing valve 5；The outlet of secondary heater 4 is connected to the second evaporator 6, and second steams
The outlet of device 6 is sent out at the top of it, communicating pipe 7 is set, the second evaporator 6 is connect with storage acid pond 8, the inlet for storing up sour pond 8 is set
There is graphite heat exchanger 9；
Primary heater 2, the first evaporator 3, secondary heater 4, the second evaporator 6 are connected with vacuum pump 10, vacuum
Under state, the boiling point of acid solution can reduce, and the first evaporator 3 and the second evaporator 6 are connect with negative-pressure air fan 11, are evaporated
Water vapour etc. is recycled to corresponding device by negative-pressure air fan and is collected.
Graphite heat exchanger 9 is the cylindrical heat exchanger being set up in parallel, and the heat exchanger tube 12 of several vertical and horizontal is arranged thereon,
Lateral heat exchanger tube 12 and longitudinal heat exchanger tube 12 are staggered, and are in the plane being mutually parallel, such heat exchanger tube knot
It when structure makes gas converting heat, will not be interfered with each other between each gas, improve the efficiency of heat exchange.2 bottom of primary heater is equipped with
Steam transfer passage 13, is heated by steam.
Acid pickle is first passed through preheater and preheated by the utility model, here, preheater is commercially available plate type preheater,
It enters back into primary heater and enters the first evaporator after being heated, water equal solvent therein is tentatively evaporated；It is laggard
Enter in secondary heater and heated, enters the second evaporator afterwards, solvent therein is evaporated again；
This practicality carry out primary heater, the first evaporator, secondary heater, the second evaporator under vacuum conditions,
The boiling point of acid reduces, and concentrated effect is more preferable.
