Description

Forced-circulation evaporator
Technical field
The utility model relates to a kind of forced-circulation evaporator, and more particularly, it relates to a kind of forced-circulation evaporator that can effectively prevent cavitation from occurring.
Background technology
Forced-circulation evaporator forms fouling or produces crystallization for avoiding the product that seethes with excitement on heating surface.For this reason, the flowing velocity in pipe must be high.Heated when circulating fluid flows through heat exchanger, the then part evaporation when the pressure of separator reduces, thus by liquid cools to should boiling temperature under pressure.Due to circulating pump, the operation of evaporimeter and the temperature difference are substantially irrelevant.The recirculation rate of material can fine adjustment.Evaporation rate is set in certain scope.In crystallization application, crystal can by regulating circulation flow rate and adopting special separator designs to separate from circulation crystal mud.Equipment adopts pump forced circulation, and have evaporation rate high, cocnentration factor is great, is specially adapted to the evaporation of concentration or viscosity higher building material.
Due in the course of the work, the temperature of the solution in pipeline is almost close to boiling point, so when entering into circulating pump from outflow tube, due to diminishing of pressure, the bubble that it is caused of solution boiling point, especially easily there is the phenomenon of cavitation erosion, circulating pump is damaged, thus affects the function of whole forced-circulation evaporator.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide forced-circulation evaporator, this fixture, by being easy to change the positioning element arranged with on it, can adapt to the processing of the bascule of different model.
For achieving the above object, the utility model provides following technical scheme: a kind of forced-circulation evaporator, comprise motor, axial-flow pump, heating clamber, vaporization chamber and circulation pipe, one end of heating clamber is connected with axial flow delivery side of pump, the other end of heating clamber is connected with vaporization chamber by mozzle, the import of axial-flow pump is connected with vaporization chamber by circulation pipe, one end of the relative axial-flow pump of described circulation pipe is provided with cooling device, described cooling device comprises the air ring be sheathed on this circulation pipe, cold runner is provided with in described air ring, described cold runner is connected with water pump, described water pump is placed in cistern.
The utility model is set to further: be provided with expansion bellow compensator between described heating clamber and mozzle.
The utility model is set to further: described expansion bellow compensator and mozzle adopt Flange joint.
The utility model is set to further: described heating clamber is vertical or horizontal.
Compared with prior art, the utility model has the advantage of: what axial flow Pump and Electromotor adopted belt to connect can effectively to avoid being caused by thermal expansion because being rigidly connected seals to axial-flow pump machine the damage caused; The expansion bellow compensator be connected between heating clamber with mozzle, eliminates the leakage problem that expansion and contraction due to mozzle cause; By being arranged on the cooling device of circulation pipe, temperature before solution flows into axial-flow pump is reduced, solution is made no longer to be in the state of closing on boiling point, the temperature avoiding the solution in pipeline of the prior art is almost close to boiling point, thus when entering axial-flow pump, easily produce the generation of the problem of cavitation erosion, extend the service time of axial-flow pump, increase the stability of whole system, extend maintenance cycle.
Accompanying drawing explanation
Fig. 1 is the overall perspective of the utility model forced-circulation evaporator embodiment.
In figure, 1, axial-flow pump; 2, motor; 3, circulation pipe; 4, mozzle; 5, heating clamber; 6, vaporization chamber; 7, gas outlet; 8, air ring; 81, cold runner; 9, cistern; 10, water pump; 11, expansion bellow compensator; 12, flange; 13, charging aperture; 14 complete liquid outlet.
Detailed description of the invention
With reference to accompanying drawing 1, the embodiment of the utility model forced-circulation evaporator is described in further details:
The present embodiment comprises motor 2, axial-flow pump 1, heating clamber 5, vaporization chamber 6 and circulation pipe 3, described heating clamber 5 is vertical or horizontal, one end of heating clamber 5 is connected with the outlet of axial-flow pump 1, the other end of heating clamber 5 is connected with vaporization chamber 6 by mozzle 4, expansion bellow compensator 11 is provided with between described heating clamber 5 and mozzle 4, described expansion bellow compensator 11 and mozzle 4 adopt flange 12 to be connected, the import of axial-flow pump 1 is connected with vaporization chamber 6 by circulation pipe 3, one end of the relative axial-flow pump 1 of described circulation pipe 3 is provided with cooling device, described cooling device comprises the air ring 8 be sheathed on this circulation pipe 3, cold runner 81 is provided with in described air ring 8, described cold runner 81 is connected with water pump 10, described water pump 10 is placed in cistern 9.
According to said structure and accompanying drawing, during work, first add feed liquid from the charge door of vaporization chamber 6, feed liquid passes into axial-flow pump 1 by circulation pipe 3, then delivers to heating clamber 5 by axial-flow pump 1, the feed liquid of heating sends into vaporization chamber 6 by mozzle 4, steam is discharged by the gas outlet 7 of vaporization chamber 6, enters axial-flow pump 1 again, move in circles with this after not merged by the feed liquid of evaporating and the feed liquid entered through charging aperture 13 through circulation pipe 3, complete the evaporation and concentration of feed liquid, complete liquid and discharge through completing liquid outlet 14, in the process, be no matter feed liquid in circulation pipe 3 or mozzle 4 be under being in the state close to boiling point all the time, so there is boiling bubble when easily entering axial-flow pump 1 from circulation pipe 3, thus easily cavitate (during the bubble-break formed in liquid flow, piece surface is constantly impacted and cause one wearing and tearing), by being arranged on the cooling device of circulation pipe 3, temperature before solution flows into axial-flow pump 1 is reduced, solution is made no longer to be in the state of closing on boiling point, the temperature avoiding the solution in pipeline of the prior art is almost close to boiling point, thus when entering axial-flow pump 1, easily produce the generation of the problem of cavitation erosion, extend the service time of axial-flow pump 1, increase the stability of whole system, extend maintenance cycle, axial-flow pump 1 and motor 2 adopt belt to be connected can effectively to avoid caused by thermal expansion because being rigidly connected the damage caused is sealed to axial-flow pump 1 machine, the expansion bellow compensator 11 be connected between heating clamber 5 with mozzle 4, eliminates the leakage problem that expansion and contraction due to mozzle 4 cause.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
