[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Depend on Figure 1 to Figure 2 A novel triple-effect heat exchange device is provided, comprising a heat exchanger body 1, a pipeline 2 and a heat exchange column 3.

[0025] Among them, multiple heat exchange columns 3 and pipelines 2 are provided, and multiple heat exchange columns 3 and pipelines 2 are installed inside the heat exchanger body 1, and the output ends and input ends of the multiple heat exchange columns 3 are interconnected through the pipelines 2; and the heat exchanger body 1 also includes a forced circulation pump 9, which is installed at the output ends and input ends of two of the pipelines 2. Specifically, the output end of the forced circulation pump 9 is connected to the end of one of the pipelines 2 away from the heat exchange column 3, and the input end of the forced circulation pump 9 is connected to the end of the other pipeline 2 away from the heat exchange column 3. Specifically, multiple heat exchange columns 3, multiple pipelines 2 and forced circulation pump 9 constitute a circulation pipeline.

[0026] When the waste liquid is transported from the inlet of the heat exchanger body 1 into the pipeline 2, the forced circulation pump 9 is started to transport the waste liquid in the pipeline 2 to the heat exchange column 3 for heat exchange treatment.

[0027] At the same time, the heat exchanger body 1 also includes a solid-liquid separator 8, which is installed between the multiple pipes 2. Specifically, the waste liquid treated by heat exchange in the heat exchange column 3 enters the solid-liquid separator 8 through the multiple pipes 2. The solid-liquid separator 8 is used to separate and treat the waste mixed in the waste liquid. Preferably, a material outlet 11 is provided at the bottom of the solid-liquid separator 8, and the material outlet 11 is used to discharge solid materials. A preheating outlet 10 is provided at the top of the solid-liquid separator 8, and the residual heat generated by the waste liquid entering the solid-liquid separator 8 is discharged from the preheating outlet 10 to avoid excessive pressure inside the solid-liquid separator 8, which may damage the solid-liquid separator 8.

[0028] Specifically, a solid-liquid separator is a separator based on the principle of centrifugal separation and used to separate precipitable solids from liquid.

[0029] More preferably, the outer wall of the pipe 2 is wrapped with thermal insulation cotton, and a clamp is provided on one side of the thermal insulation cotton. The clamp fixes the thermal insulation cotton around the outer wall of the pipe 2, thereby insulating the waste liquid transported inside the pipe 2.

[0030] Secondly, when the waste liquid is transported into the pipeline 2 from the inlet of the heat exchanger body 1, the forced circulation pump 9 is started to generate suction, so that the waste liquid in the pipeline 2 is transported to one of the heat exchange columns 3, and then the waste liquid enters the remaining heat exchange columns 3 in turn through the other pipelines 2, and the waste liquid returns to the solid-liquid separator 8 from the last heat exchange column 3 through the pipeline 2.

[0031] It is important to note that the pore size of the heat exchange column 3 in the present application is increased to 1.5 times of the original size, which will bring about a better heat transfer effect and increase the efficiency of heat conduction.

[0032] Depend on Figure 1 to Figure 2 It is shown that a plurality of steam adding control mechanisms and a plurality of observation mechanisms are installed on one side of the plurality of heat exchange columns 3 .

[0033] A plurality of steam adding control mechanisms are respectively arranged on one side of the plurality of heat exchange columns 3 , and the steam adding control mechanism comprises a steam heating input pipe 4 , an automatic control component 5 and a steam condensate water outlet pipe 6 .

[0034] The steam heating input pipe 4 is arranged on the outer wall at the top end of the heat exchange column 3. The automatic control component 5 is an automatic control valve. The automatic control valve is arranged in the middle of the steam heating input pipe 4. The heated steam enters the heat exchange column 3 through the steam heating input pipe 4. The automatic control valve can control the amount of steam added to make the control of various heating temperatures more precise.

[0035] Briefly, an automatic control valve is a valve that uses a combination of sensors, valve actuators, and control modules. It can transmit signals from sensors to the control module to issue instructions to operate the valve actuator. The design of this valve allows fluid parameters such as flow and pressure to be accurately controlled.

[0036] Specifically, the heat exchange column 3 has a complete steam transport system. When the heat provided by the steam transport system to the heat exchange column 3 is insufficient, the automatic control valve opens, and the heated steam enters the heat exchange column 3 through the steam heating input pipe 4.

[0037] The steam condensate water outlet pipe 6 is arranged on the outer wall of the bottom end of the heat exchange column 3 , and the water condensed inside the heat exchange column 3 is discharged through the steam condensate water outlet pipe 6 .

[0038] Depend on Figure 1 to Figure 2 It is shown that a plurality of observation mechanisms are respectively arranged on the outer walls of the tops of the plurality of heat exchange columns 3, and the observation mechanisms include a fixing part, an observation mirror 7, a rotating part and a mirror cover.

[0039] The fixing part is a bolt, and the observation mirror 7 is installed on the top of the heat exchange column 3 by the bolt. The rotating part is a hinge, one side of the hinge is installed on the outer wall of the heat exchange column 3, and the mirror cover is installed on the other side of the hinge. The mirror cover is buckled on the surface of the observation mirror 7. By rotating the mirror cover, the operating status and scaling of the equipment can be easily observed through the observation mirror 7, and possible problems can be discovered and solved in time, which is helpful to maintain and optimize the operation of the equipment.

[0040] Beneficial effects obtained by the heat exchanger body 1, the pipeline 2, the heat exchange column 3, multiple steam addition control mechanisms and multiple observation mechanisms: The utility model can effectively increase the heat exchange area without changing the pump power by installing the heat exchange column 3 at the outlet of the forced circulation pump 9, thereby solving the problem of insufficient evaporation heat exchange area and improving the efficiency of evaporating wastewater.

[0041] By installing the observation mirror 7, the operating status and scaling of the equipment can be easily observed, and possible problems can be discovered and solved in time, which is helpful for maintaining and optimizing the operation of the equipment.

[0042] The use of steam heating combined with an automatic control valve to control the amount of heating steam can achieve more precise temperature control and improve the controllability and accuracy of heating.

[0043] When the utility model is used, when the waste liquid is transported into the pipeline 2 from the inlet of the heat exchanger body 1, the forced circulation pump 9 is started to generate suction, so that the waste liquid in the pipeline 2 is transported to one of the heat exchange columns 3, and then the waste liquid enters the remaining heat exchange columns 3 in turn through the other pipelines 2, and the waste liquid returns to the solid-liquid separator 8 from the last heat exchange column 3 through the pipeline 2.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
