Description
Technical field
The utility model relates to a kind of mud quenching and tempering device, particularly relates to a kind of hot quenching and tempering device mud being carried out pyrohydrolysis.
Background technology
Research shows, after sludge high temperature heating (pyrohydrolysis), dewatering improves, and water-soluble COD improves, and can carry out the subsequent treatment such as deep dehydration or anaerobic digestion, therefore, at present, a lot of to its research.
During initial proposition pyrohydrolysis technology path, be because in pyrohydrolysis process, do not have the phase transition process of water, therefore, observable index heated drying is much lower.But along with going deep into of research, there are two difficult problems in pyrohydrolysis technique: if use thickened sludge to carry out pyrohydrolysis, although its heat transfer property is good, because the water yield that need heat is too large, energy consumption is also very high, and, also produce a large amount of unmanageable pyrohydrolysis black liquor; If use dewatered sludge to carry out pyrohydrolysis, its energy consumption is low, and black liquor amount is low, but due to the conductivity of heat extreme difference of dewatered sludge, make the heat time very long, productivity ratio is low, and reactor volume is excessive and be difficult to manufacture.
In order to solve these difficult problems, most researcher have selected the process route of " steam direct heating " and " flash distillation recovers energy ".This also just means, artificial has introduced the phase transition process of water, and the initial advantage of pyrohydrolysis technique is exhausted.If add the disposal cost of hydrolysis black liquor, the cost of pyrohydrolysis technique is also very high.
The equipment that the utility model proposes, while adhering to this advantage of the anhydrous phase transformation of pyrohydrolysis technique, improves the heat conductivility of mud, and the volume of its reactor can receptible scope at one, and the large-scale application for pyrohydrolysis technique provides an approach.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of anhydrous phase transformation, capacity usage ratio are high, the acceptable pyrohydrolysis reactor of reactor volume, comprising: enter dredge pump, reactor and regulator board.It is characterized in that, described in enter dredge pump outlet and be connected with described reactor inlet is closed, described reactor exit has regulator board.Described reactor is provided with heating heat exchanger, heat transfer oil heater, recovery heat exchanger, conduction oil reflux pump and agitator.Described heat-conducting oil heating outlet of still is closed with described heating heat exchanger entrance and is connected, described heating heat exchanger outlet is closed with described conduction oil reflux pump entrance and is connected, described conduction oil reflux pump outlet is closed with described recovery heat exchanger entrance and is connected, and described recovery heat exchanger exit is closed with described heat transfer oil heater entrance and is connected.
Described heating heat exchanger and reclaim in heat exchanger the helical duct be welded with around reactor.The blade Length discrepancy of described agitator, its long end is close to reactor wall.
Compared with prior art, the beneficial effect of a kind of sludge hot hydrolysis reactor of the present utility model is: anhydrous phase transformation, capacity usage ratio are high, reactor volume can accept.
Accompanying drawing explanation
Fig. 1 is a kind of sludge hot hydrolysis reactor structural representation of the utility model embodiment
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment:
A kind of sludge hot hydrolysis reactor as shown in Figure 1, comprising: enter dredge pump 1, reactor 2 and regulator board 3.Enter dredge pump 1 and export be connected closed with reactor 2 entrance, there is regulator board 3 in reactor 2 exit.Reactor 2 is provided with heating heat exchanger 2-1, heat transfer oil heater 2-2, reclaims heat exchanger 2-3, conduction oil reflux pump 2-4 and agitator 2-6.Heat transfer oil heater 2-2 exports be connected closed with heating heat exchanger 2-1 entrance, heating heat exchanger 2-2 exports be connected closed with conduction oil reflux pump 2-4 entrance, conduction oil reflux pump 2-4 exports and is connected with recovery heat exchanger 2-3 entrance is closed, and recovery heat exchanger 2-3 outlet is closed with heat transfer oil heater 2-2 entrance and is connected.The helical duct 2-5 around reactor is welded with in heating heat exchanger 2-1 and recovery heat exchanger 2-3.The blade Length discrepancy of agitator 2-6, its long end is close to the wall of reactor 2.
Briefly introduce as follows to the operation principle of the present embodiment below:
Mud adds in reactor 2 by entering dredge pump 1, and mud, in reactor 2, is similar to and travels forward with the state of plug-flow mode.First mud carry out heat exchange with heating heat exchanger 2-1 and be heated to assigned temperature, concurrent heat-dissipating hydrolysis; Subsequently, the pyrohydrolysis mud of HTHP carries out heat exchange with recovery heat exchanger 2-3 and is cooled, the heat reclaimed is carried by conduction oil, and provide pressure by conduction oil reflux pump 2-4, in press-in heat transfer oil heater 2-2, conduction oil enters heating heat exchanger 2-1 after heating up in heat transfer oil heater 2-2, the mud entered after heating.
In pyrohydrolysis reactor 2, mud plug-flow speed is forward slowly, and the heat conductivility of mud is very poor, and heat transfer rate is extremely slow.Therefore, this device has installed agitator 2-6 especially, and its effect manufactures turbulent environment in the plane perpendicular with direction of advance, improves heat transfer rate, simultaneously, due to the effect of helical duct 2-5, conduction oil travels forward as spiral around reactor 2, makes conduction oil both in turbulence state, again lentamente along the axially-movable of reactor 2, these two measures of the present utility model, make the overall heat-transfer coefficient of mud increase, thus make this device in a rational volume range.
Generally, the temperature of sludge hot hydrolysis, at about 180 DEG C, by entering the acting in conjunction of dredge pump 1 and regulator board 3, maintaining the pressure in reactor 2, water is not undergone phase transition.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
