Description
Technical field
The utility model relates to a kind of chemical production equipment, relates in particular to a kind of white carbon black thin pulp cycle heat exchange and prepares hot-water system.
Background technology
Chemical reaction comprises many processing parameters, and for example temperature of reaction is one of processing parameter.Approximately 80～95 ℃ of the temperature of reaction of general precipitated silica.
In precipitated silica production process, need with a large amount of hot water as reaction process water.
Approximately 80～90 ℃ of white carbon black temperature of reaction.Reacted grout carries out filtration washing with plate-and-frame filter press.Because domestic filter press filter board material mostly is regenerating polypropylene, the grout that temperature is too high enters sheet frame and easily causes filter plate distortion, the aging structure deteriorate that causes.
General white carbon black enterprise all will carry out heat exchange to grout reduces grout temperature, and completely reacted white carbon black grout proceeds to thin pulp groove, during pass through tubular heat exchanger.In tubular heat exchanger, inject cold water, cold water and the heat exchange of white carbon black grout have just obtained hot water.Gained hot water can be used as reaction process water, reduces reaction process energy consumption, enhances productivity.
In order to improve the utilization ratio of reactor, completely reacted white carbon black grout must be sent into thin pulp groove as early as possible, though white carbon black grout is through a heat exchange like this, temperature still has 70～75 ℃.The heat energy of white carbon black grout is not fully used.
Utility model content
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and a kind of system that can make full use of white carbon black thin pulp heat is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme,
A white carbon black thin pulp cycle heat exchange preparation system, comprises the pump housing, interchanger and thin pulp groove; The described pump housing comprises the first import, circulation import and the first outlet, and described interchanger comprises the second import and the second outlet, and described thin pulp groove comprises triple feed inlet, the 3rd outlet and thin pulp outlet; The first import of the described pump housing is for reacting entering of grout, and the first outlet of the pump housing connects the second import of interchanger, and the second outlet of interchanger connects the triple feed inlet of thin pulp groove, and the 3rd outlet of thin pulp groove connects the circulation import of the pump housing; Described the 3rd outlet is provided with by-pass valve control with circulation import junction; Described thin pulp outlet is for the output of grout.
Wherein, described interchanger is surface-type heat exchanger.
Wherein, described surface-type heat exchanger is tube and shell heat exchanger or double-pipe exchanger.
The beneficial effects of the utility model are: described grout, and by pumping of pump, proceed to interchanger and carry out heat exchange, then enter described thin pulp groove.Grout, by after thin pulp groove internal recycle, is opened described by-pass valve control, the pump housing described in described grout enters again, and through interchanger, heat exchange is cooling again, then enters described thin pulp groove, finally from the thin pulp outlet of thin pulp groove, exports thin pulp.By white carbon black thin pulp cycle heat exchange preparation system of the present utility model, can make the heat energy of white carbon black grout be fully utilized.
Accompanying drawing explanation
Figure 1 shows that the structural representation of white carbon black thin pulp cycle heat exchange preparation system of the present utility model.
Embodiment
By describing technology contents of the present utility model, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
See also Fig. 1, as shown in the figure, a kind of white carbon black thin pulp of the utility model cycle heat exchange preparation system, comprises the pump housing, interchanger and thin pulp groove; The described pump housing comprises the first import, circulation import and the first outlet, and described interchanger comprises the second import and the second outlet, and described thin pulp groove comprises triple feed inlet, the 3rd outlet and thin pulp outlet; The first import of the described pump housing is for reacting entering of grout, and the first outlet of the pump housing connects the second import of interchanger, and the second outlet of interchanger connects the triple feed inlet of thin pulp groove, and the 3rd outlet of thin pulp groove connects the circulation import of the pump housing; Described thin pulp outlet is for the output of grout.In this technical scheme, completely reacted white carbon black grout is pumped via interchanger by pump, then to thin pulp groove.In this process, open the cold water switch of described interchanger simultaneously, carry out heat exchange, by regulating Cold water tap aperture to control outlet hot water temperature.Turn for the first time material finish after, close the first import.Open grout in circulation import thin pulp groove by the 3rd described outlet, enter the pump housing pumping by pump, make grout again enter described interchanger and carry out secondary circulation heat exchange, simultaneously by regulating the Cold water tap aperture of interchanger to control outlet hot water temperature.In said process, the grout heat exchange in white carbon black reactor and the grout secondary circulation heat exchange in the thin pulp groove operation of staggering.The improvement of above-mentioned embodiment has, and described interchanger is surface-type heat exchanger, preferred, can adopt tube and shell heat exchanger or double-pipe exchanger.In this embodiment, only take tube and shell heat exchanger or double-pipe exchanger to be described as example, for the kind of other feasible interchanger, at this, just do not repeat.
Said system, in real work, concrete is as follows:
Embodiment mono-: 40M
3the white carbon black grout that temperature is 90 ℃ through the pump housing and interchanger, while proceeding to thin pulp groove, through described interchanger, can be made 15 tons of 50 ℃ of hot water through a heat exchange from reactor, and white carbon black grout temperature drops to 76 ℃.20 ℃ of cold water temperatures, heat exchange efficiency approximately 80%.Then, open described by-pass valve control, make the grout in thin pulp groove pass through again described interchanger, then the white carbon black grout cycle heat exchange of 76 ℃ in thin pulp groove is dropped to 60 ℃, make again 15 tons of 50 ℃ of hot water, heat exchange efficiency 70%.
