For fear of the generation of above-mentioned situation, need to carry out Real-Time Monitoring to described lining 2, in the time that described lining 2 is damaged, can learn in time, and repair as early as possible, prevent that larger accident from occurring.Therefore, described evaporator also comprises the circuit for detection of described lining 2 damaged situations, and described circuit comprises the first electrode 3, the second electrode 4, power supply 5 and measurement mechanism 6.Particularly, described the first electrode 3 is arranged on the outside of described metal shell 1, is connected with described metal shell 1; Described the second electrode 4 is arranged on the inwall of described lining 2, and described the second electrode 4 insulate with described metal shell 1, and described the first electrode 3 is connected by wire with described the second electrode 4; Described power supply 5 is connected in described wire, for whole circuit provides power supply; Described measurement mechanism 6 is connected in described wire, for measuring the variation of described circuit electric signal.
In the time that breakage occurs described lining 2, the liquid of described evaporator inside will directly contact described metal shell 1.Now, will be by described liquid conducting between described the second electrode 4 and described metal shell 1, thus make whole circuit in conducting state, the registration of described measurement mechanism 6 will change.By the variation of described measurement mechanism 6 registrations, just can Real-Time Monitoring described in lining 2 whether damaged, can in the time that described lining 2 is damaged, keep in repair timely, avoid metal shell 1 described in described liquid corrosion to cause leak of liquid.
Fig. 2 is the structural representation of first preferred embodiment of the utility model evaporator, as shown in Figure 1, described in described evaporator, measurement mechanism 6 is selected reometer 62, and described reometer 62 can be measured the size of current in described circuit, thereby can monitor the variation of electric current in described circuit.In order to prevent producing super-high-current in circuit, in described circuit, be also connected in series a resistance 61.
In the time that the described lining 2 of described evaporator does not damage, described the first electrode 3 insulate by described lining 2 mutually with described the second electrode 4, and causing whole circuit is off-state, and the registration of described reometer 62 is close to zero.In the time that the described lining 2 of described evaporator is damaged, the liquid of described evaporator inside is described the second electrode 4 and described metal shell 1 conducting, conducting between described the first electrode 3 and described the second electrode 4, thus make described circuit become closure state.Now, the electric current in described circuit can increase, and can monitor the increase of electric current by described reometer 62, and described evaporator needs on-call maintenance, otherwise can cause metal shell 1 perforation that is corroded, and makes leak of liquid.
Fig. 3 is the structural representation of second preferred embodiment of the utility model evaporator, as shown in Figure 3, different from described first preferred embodiment is, described measurement mechanism 6 in described second preferred embodiment comprises resistance 61 and for measuring the voltage table 63 of described resistance 61 both end voltage sizes, described resistance 61 is connected in described circuit, described voltage table 63 is connected in parallel on the two ends of described resistance 61, measure the variation of the magnitude of voltage at described resistance 61 two ends by described voltage table 63, monitor the damaged situation of described lining 2.In the time that breakage occurs described lining 2, described circuit is in conducting state, and it is large that the registration of described voltage table 63 can become.In the time that the registration of described voltage table 63 becomes large, illustrate that breakage has occurred described lining 2, now need to repair in time described lining 2.
Fig. 4 is the structural representation of the 3rd preferred embodiment of the utility model evaporator.As shown in Figure 4, described measurement mechanism 6 can be selected the reometer 62 in described first preferred embodiment, also the voltage table that is parallel with resistance 61 63 in described second preferred embodiment can be used, other electric signal measurement instrument (such as multimeter etc.) can also be selected.In the 3rd preferred embodiment shown in Fig. 4, described evaporator also comprises current transducer 7 and display 8, and the current input terminal of described current transducer 7 is connected in described circuit, and described display 8 is connected with the current output terminal of described current transducer 7.Described current transducer 7 can convert the current signal of input to standard industry control signal (for example: 4-20mA signal), current output terminal by described transmitter is transported to control signal in described display 8, described display 8 receives after described control signal, shows corresponding captions or picture cues.For example, in the time that described lining 2 is damaged, described current transducer 7 detects the electric current in described circuit, and change into 4-20mA signal and be transported to described display 8, described display 8 shows captions such as " lining have breakage " or " please repair lining " after receiving signal, remind staff to repair timely described lining 2, prevent that larger accident from occurring.
In the 4th preferred embodiment, for in the time there is breakage in described lining 2, learn in time the damaged general orientation of described lining 2, described evaporator is provided with multiple described circuit, described the second electrode 4 in different described circuit is separately positioned on the diverse location of the inwall of described evaporator lining 2, more preferably, described the second electrode 4 is evenly distributed on the inwall of described evaporator lining 2.Fig. 5 is the front view of the installation site of the second electrode in the 4th preferred embodiment of the utility model evaporator; Fig. 6 is the upward view of the installation site of the second electrode in the 4th preferred embodiment of the utility model evaporator.As shown in Figure 5 or Figure 6, described evaporator is provided with the described circuit of eight covers (installation site of described the second electrode 4 is only shown in Fig. 5 or Fig. 6), different described circuit shares same described the first electrode 3, and described the first electrode 3 is arranged on the bottom outside of described evaporator.
Due under normal conditions, in the tank body of evaporator, be loaded with the slurries of 2/3 liquid level of the height of whole described evaporator, easily there is corrosion leakage lower than liquid level place and tank base.Therefore, 4 described the second electrodes 4 are wherein separately positioned on to the contour circumferential position that the middle and high degree of corrosion protective lining 2 is 1/2 tank body height, and are evenly arranged; Other 4 described the second electrodes 4 are arranged on to the contour circumferential position near described base of evaporator, and are evenly arranged.Wherein, as shown in Figure 6, described second electrode 4 of two contour circumferential positions is staggered.
Because the slurries in described evaporator are electrolyte solutions, there is electric conductivity, when the composition of electrolyte in slurries and concentration one timing, its resistance coefficient is certain.In the time that described lining 2 is damaged, the size of the electric current producing in described circuit and corrosion protective lining 2 breaking points have fixing corresponding relation to the distance of described the second electrode 4, and the distance of described breaking point and described the second electrode 4 is far away, and the electric current producing in described circuit is just less, otherwise electric current is larger.Accordingly, can judge according to the size of the registration in different measurement mechanism 6 approximate location of described lining 2 breaking points.
