Abstract
The utility model discloses a dirty comdenstion water recycling system, heavily defiling condensate draining, strip tower and gently defiling the condensate draining including what connect gradually, gently the dirty cool basin that congeals is connected in causticization workshop section. Heavily dirty comdenstion water can arrive causticization workshop section by the retrieval and utilization behind strip tower strip, reduced the quantity of clean water, has reduced wastewater treatment capacity, reduces the sewage treatment cost and has practiced thrift the energy. The delivery port of heavily dirty condensate draining is connected in the pre -heater, and the pre -heater is including heavily dirty water inlet, heavily dirty delivery port, gently dirty water inlet and light dirty delivery port, and the heavily dirty delivery port of pre -heater is connected in the water inlet of strip tower, and the delivery port of strip tower is connected in the light dirty water inlet of pre -heater, and the light dirty delivery port of pre -heater is connected in light dirty condensate draining, and gently dirty condensate draining is connected in causticization workshop section. The waste heat that will heavily defile the comdenstion water passes through the heat exchanger and transmits for the cool water that congeals of light dirt, practices thrift the primary steam energy, increases the emergence of going into the gently temperature of dirty comdenstion water of causticization section, the causticization reaction of being convenient for.
Description
Technical field
The utility model belongs to technical field of papermaking and pulping equipment, specifically, relates to the foul condensate reclaiming system of evaporation section.
Background technology
Traditional paper industry one to being use water rich and influential family, and produces a large amount of sewage, and papermaking producer remains high for the expense of sewage disposal every year.
Evaporation section uses a large amount of steam, and the black liquor of evaporation section can evaporate a lot of pollutant, and therefore evaporation section can produce a large amount of foul condensates, and in addition, the heavy sewage of heavy foul condensate groove, also comprises the sewage that pulping and digesting system is come.In prior art, these dirty cold water are that the treatment tank being directly discharged into environmental protection center carries out processing, and this not only wastes the water resource of still recoverable, and causes very large burden to sewage disposal.
Utility model content
The utility model overcomes shortcoming of the prior art, provides foul condensate reclaiming system, will weigh foul condensate and recycle, and reduce the waste to water resource, economize energy, and reduce the pressure of water treatment, and save water treatment expense.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Foul condensate reclaiming system, comprise the heavy foul condensate groove, stripper and the light foul condensate groove that connect successively, light dirty cool solidifying tank is connected to caustic room.
Wherein, the delivery port of heavy foul condensate groove is connected to preheater, preheater comprises heavy dirty water inlet, heavy dirty delivery port, light dirty water inlet and light dirty delivery port, the dirty delivery port of weight of preheater is connected to the water inlet of stripper, the delivery port of stripper is connected to the light dirty water inlet of preheater, the light dirty delivery port of preheater is connected to light foul condensate groove, and light foul condensate groove is connected to caustic room.
Wherein, preheater is plate type heat exchanger.
Wherein, feeding filter is provided with between the dirty delivery port of the weight of preheater and the water inlet of stripper.
Compared with prior art, the beneficial effects of the utility model are:
Foul condensate reclaiming system described in the utility model, comprise the heavy foul condensate groove, stripper and the light foul condensate groove that connect successively, light dirty cool solidifying tank is connected to caustic room.Heavy foul condensate can be back to use caustic room after stripper stripping, decreases the consumption of clean water, reduces sewage load, reduces cost of sewage disposal and has saved the energy;
The delivery port of heavy foul condensate groove is connected to preheater, preheater comprises heavy dirty water inlet, heavy dirty delivery port, light dirty water inlet and light dirty delivery port, the dirty delivery port of weight of preheater is connected to the water inlet of stripper, the delivery port of stripper is connected to the light dirty water inlet of preheater, the light dirty delivery port of preheater is connected to light foul condensate groove, and light foul condensate groove is connected to caustic room.The waste heat of heavy foul condensate is passed to light dirty cool solidifying water by heat exchanger, saves the primary steam energy, be added to the temperature of the light foul condensate of causticization section, be convenient to the generation of causticizing reaction;
Preheater is plate type heat exchanger, and structure is simple, and cost is low, easily installs and uses;
Be provided with feeding filter between the dirty delivery port of weight of preheater and the water inlet of stripper, prevent the impurity blocking stripper in foul condensate, further filter cleaning foul condensate, is convenient to reuse.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model, in the accompanying drawings:

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1 and Figure 2, foul condensate reclaiming system described in the utility model, comprise the heavy foul condensate groove, stripper and the light foul condensate groove that connect successively, light dirty cool solidifying tank is connected to caustic room.Heavy foul condensate can be back to use caustic room after stripper stripping, decreases the consumption of clean water, reduces sewage load, reduces cost of sewage disposal and has saved the energy.
The delivery port of heavy foul condensate groove is connected to preheater, preheater comprises heavy dirty water inlet, heavy dirty delivery port, light dirty water inlet and light dirty delivery port, the dirty delivery port of weight of preheater is connected to the water inlet of stripper, the delivery port of stripper is connected to the light dirty water inlet of preheater, the light dirty delivery port of preheater is connected to light foul condensate groove, and light foul condensate groove is connected to caustic room.The waste heat of heavy foul condensate is passed to light dirty cool solidifying water by heat exchanger, saves the primary steam energy, be added to the temperature of the light foul condensate of causticization section, be convenient to the generation of causticizing reaction.
Preheater is plate type heat exchanger.Structure is simple, and old low, easily installs and uses.
Feeding filter is provided with between the dirty delivery port of weight of preheater and the water inlet of stripper.Prevent the impurity blocking stripper in foul condensate.Further filter cleaning foul condensate, is convenient to reuse.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
