Technical field
The utility model belongs to technical field of chemical, relates to a kind of evaporation technique, is specifically related to the tower vapo(u)rization system of a kind of cold water.
Background technology
Domestic existing vaporising device is thermal source mainly with steam greatly, and it imitates number from the single-action to the multiple-effect, and in the majority with triple effect.For guaranteeing respectively to imitate thermograde, most end effect secondary steams is the low vapours of negative pressure, because of not convenient use, mostly adopts cooling water to absorb, then will recycle after cooling water temperature with cooling tower.Like this, not only waste the considerable evaporation latent heat of end effect secondary steam heat, also will in the cold water process, drop into energy.Because national energy policy is becoming tight day by day, utilize existing steam to carry out reducing energy consumption for thermal source and the vaporising device of being furnished with the waste heat from water cooling tower treatment system, seem very urgent.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, has proposed the tower vapo(u)rization system of a kind of cold water, makes the indirect steam of steam raising unit end effect consume by need the energy that treatable used heat becomes cold water formula evaporating column.
The utility model comprises cold water formula evaporating column, circulatory pool, heat exchanger and steam raising unit.
The casing that described cold water formula evaporating column is bottom surface opened, be provided with the honeycomb packing layer in casing, the top of honeycomb packing layer is the spray chamber, spray is provided with liquid distributor in chamber, the end face of casing is provided with humid air outlet and material liquid import, and the bottom surface that casing is opened is as the air intlet of cold water formula evaporating column.
Be provided with liquid collecting plate in described circulatory pool, liquid collecting plate is the flat board be obliquely installed, and an end is fixed on the sidewall of circulatory pool, the downward-sloping and unsettled setting of the other end, and angle of inclination is less than or equal to 15 °, guarantees that liquid slowly enters the circulatory pool bottom; The sidewall of circulatory pool has circulation fluid delivery outlet and semi-finished product liquid delivery outlet near bottom surface.
Described heat exchanger is tubular heat exchanger; The steam raising unit bottom is provided with the finished fluid delivery outlet.
Described cold water formula evaporating column be arranged on circulatory pool directly over, the circulation fluid delivery outlet of circulatory pool is connected with the input port of circulating pump, the output port of circulating pump is connected with an end of the heat exchanging pipe of heat exchanger, the other end of heat exchanging pipe is connected with liquid distributor; The semi-finished product liquid delivery outlet of circulatory pool is connected with the input port of rear pump, and the output port of rear pump is connected with the semi-finished product liquid input port of steam raising unit.
The utility model utilizes humidity unsaturated air flash principle to be evaporated, therefore particularly applicable to high temperature low humidity area.The utlity model has following beneficial effect:
1, make the indirect steam of steam raising unit end effect consume by need the energy that treatable used heat becomes cold water formula evaporating column.
2, make the cooling tower system become waste-heat recovery device by the used heat treating apparatus of steam raising unit.
3, cold water formula evaporating column essence is the front-packed evaporator of steam raising unit, is equivalent to and many effect evaporations, therefore production capacity promotes to some extent.
4, the utility model provides a kind of reducing energy consumption approach for existing vaporising device, for the industry energy conservation consumption reduction, increases the benefit and has fairly obvious meaning with survival ability.
The accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the tower vapo(u)rization system of cold water comprises cold water formula evaporating column 1, circulatory pool 2, heat exchanger 3 and steam raising unit 4.
The casing that cold water formula evaporating column 1 is bottom surface opened, be provided with honeycomb packing layer 1-1 in casing, the top of honeycomb packing layer 1-1 is spray chamber 1-2, be provided with liquid distributor 1-3 in spray chamber 1-2, the end face of casing is provided with humid air outlet a and material liquid import b, and the bottom surface that casing is opened is as the air intlet c of cold water formula evaporating column 1.
Be provided with liquid collecting plate 2-1 in circulatory pool 2, liquid collecting plate 2-1 is the flat board be obliquely installed, and an end is fixed on the sidewall of circulatory pool 2, the downward-sloping and unsettled setting of the other end, angle of inclination ≤ 15 °; The sidewall of circulatory pool 2 has circulation fluid delivery outlet and semi-finished product liquid delivery outlet near bottom surface.
Heat exchanger 3 is tubular heat exchanger; 4 bottoms, steam raising unit are provided with finished fluid delivery outlet d.
Cold water formula evaporating column 1 be arranged on circulatory pool 2 directly over, the circulation fluid delivery outlet of circulatory pool 2 is connected with the input port of circulating pump 5, the output port of circulating pump 3 is connected with the end of the heat exchanging pipe 3-1 of heat exchanger 3, and the other end of heat exchanging pipe 3-1 is connected with liquid distributor 1-3; The semi-finished product liquid delivery outlet of circulatory pool 2 is connected with the input port of rear pump 6, and the output port of rear pump 6 is connected with the semi-finished product liquid input port of steam raising unit 4.
