Technical Field

[0001] This utility model relates to the technical field of condensate recovery and filtration equipment, and in particular to a condensate recovery filtration device. Background Technology

[0002] Condensate typically refers to liquid that transforms from a gaseous or vaporous state through a cooling process. During condensation, it may carry some metallic impurities caused by pipe corrosion and some solid and oily impurities caused by the aging of machine components. Therefore, condensate recovery and filtration equipment is needed to treat the condensate.

[0003] Existing condensate recovery and filtration equipment, such as the Chinese utility model patent CN222865625U (authorization announcement number: A steam condensate recovery device), represents a class of prior art whose main structure includes a water storage tank, a float level switch, a filter screen, and brushes. The water storage tank stores the condensate, the float level switch controls the liquid level in the water storage tank, the filter screen filters the condensate, and the brushes clean the filter screen.

[0004] However, the existing technology and equipment still have the following problems when in use: after long-term operation, the existing machines need to be manually cleaned by workers after shutdown, resulting in poor machine usability. In addition, steam may carry oil impurities when condensing, and the existing machines lack the ability to separate and filter oil impurities, resulting in poor recovery of condensate. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a condensate recovery filtration device that facilitates machine cleaning without shutting down the machine, thereby improving its usability, and that separates oily impurities in the condensate by incorporating an oil-water separator, thereby improving the machine's recovery efficiency.

The discharge device, two filtration devices, oil-water separation device, and stirring device are all installed on the measuring device, and the cyclone separation device is installed on the oil-water separation device. The measuring device measures the quantity of condensate, the discharge device discharges the condensate, the filtration devices filter the condensate, the oil-water separation devices remove oily impurities from the condensate, the cyclone separation device separates solid impurities from the condensate in one step, and the stirring device stirs the condensate to prevent fungal growth.

[0007] Preferably, the measuring device includes a support frame, four piezoelectric weights, and a liquid storage tank. Two mounting slots are respectively provided on the left and right sides of the support frame. The four piezoelectric weights are fixedly installed in the four mounting slots of the support frame. The liquid storage tank is placed on top of the four piezoelectric weights and is slidably mounted on the support frame. Two mounting slots and a drain outlet are provided at the top of the liquid storage tank, and an inlet is provided at the rear end of the tank. The liquid storage tank holds the condensate, and the piezoelectric weights measure the weight of the liquid storage tank, thereby measuring the quantity of condensate.

The hydrophilic-oleophobic filter elements only allow the condensate to pass through, thereby causing the oil impurities to accumulate inside the separation cylinder, thus achieving the separation of condensate and oil impurities. When too much oil impurity accumulates, it can be automatically discharged to the outside through pipe two.

[0025] like Figure 2 As shown, the measuring device 01 includes a support 11, four piezoelectric weights 12, and a liquid storage tank 13. The support 11 has two mounting slots 1 on its left and right sides, and the four piezoelectric weights 12 are fixedly installed in the four mounting slots 1 of the support 11. The liquid storage tank 13 is placed on top of the four piezoelectric weights 12 and is slidably installed on the support 11. The top of the liquid storage tank 13 has two mounting slots 2 and a drain port, and the rear end of the liquid storage tank 13 has a liquid inlet.

[0026] like Figure 3 As shown, the discharge device 02 includes a second bracket 21, an impeller pump 22, and a first pipe 23. The second bracket 21 is fixedly installed on the top of the first bracket 11, the impeller pump 22 is installed on the top of the second bracket 21, one end of the first pipe 23 is installed on the side of the impeller pump 22, and the first pipe 23 passes through the discharge port of the liquid storage tank 13 and is installed on the liquid storage tank 13.

[0027] like Figure 4 As shown, the filter device 03 includes a support 31 and a filter screen 32. The support 31 is slidably installed in a mounting slot 2 of the piezoelectric weight block 12. A handle is provided at the top of the support 31. The filter screen 32 is installed on the support 31. The two filter devices 03 are respectively slidably installed in two mounting slots 2 of the liquid storage tank 13.

[0028] like Figure 5As shown, the oil-water separation device 04 includes a support 41, a separation cylinder 42, multiple supports 43, a coalescing filter element 44, two hydrophilic and oleophobic filter elements 45, a pipe 2 46, a pipe 3 47, and a pipe 48. The support 41 is installed on the ground, the separation cylinder 42 is installed on the support 41, the multiple supports 43 are evenly spaced inside the separation cylinder 42, and multiple through holes are provided on the multiple supports 43. The coalescing filter element 44 and the two hydrophilic and oleophobic filter elements 45 are fixedly installed on the multiple supports 43. The pipe 2 46 is installed at the top of the separation cylinder 42, one end of the pipe 3 47 is installed at the bottom of the two hydrophilic and oleophobic filter elements 45, and the other end of the pipe 3 47 is connected to the liquid inlet of the liquid storage tank 13 through a hose. One end of the pipe 48 is installed at the bottom of the coalescing filter element 44.

[0029] like Figure 6 As shown, the cyclone separator 05 includes a collection box 51, a cyclone separator 52, and a pipe 53. The collection box 51 is installed on the ground, the cyclone separator 52 is installed on the top of the collection box 51, and the pipe 53 is installed on the top of the cyclone separator 52. The other ends of the pipe 53 and the pipe 48 are connected.

[0030] First, the condensate is introduced into the hydrocyclone separator 52. The hydrocyclone separator 52 uses its own structure to separate solid impurities from the condensate through cyclone separation. The collection box 51 stores the separated solid impurities. Then, the condensate enters the separation cylinder 42, where the coalescing filter element 44 disperses the condensate and oil impurities, breaking up the emulsion state of the oil impurities and promoting their separation from the condensate. The hydrophilic-oleophobic filter element 45 allows only condensate to pass through, thus causing the oil impurities to accumulate inside the separation cylinder 42. This achieves the separation of condensate and oil impurities. When oil impurities accumulate excessively, they can be automatically discharged to the outside through pipe 46. Then, the condensate enters the storage tank 13 for storage. At the same time, the filter screen 32 filters the condensate, and the piezoelectric weighing block 12 measures the weight of the storage tank 13 to measure the amount of condensate. When there is too much condensate, the condensate input can be stopped to prevent the storage tank 13 from storing too much condensate. When it is necessary to drain the condensate, the impeller pump 22 is turned on, and the impeller pump 22 operates to drain the condensate inside the storage tank 13.

[0031] Example 2

[0032] In addition to Example 1, it also includes:

[0033] like Figure 7As shown, the stirring device 06 includes a stirring paddle 61, a reducer 62, and a motor 63. The stirring paddle 61 is rotatably mounted inside the bottom of the liquid storage tank 13. The reducer 62 is fixedly mounted at the bottom of the liquid storage tank 13 and is rotatably connected between the liquid storage tank 13 and the stirring paddle 61. The motor 63 is fixedly mounted at the bottom of the reducer 62 and provides power to the stirring paddle 61 through the reducer 62.

[0034] First, the condensate is introduced into the hydrocyclone separator 52. The hydrocyclone separator 52 uses its own structure to separate solid impurities in the condensate through cyclone separation. The collection box 51 stores the separated solid impurities. Then, the condensate enters the separation cylinder 42, where the coalescing filter element 44 disperses the condensate and oil impurities, breaking up the emulsion state of the oil impurities and promoting their separation from the condensate. The hydrophilic-oleophobic filter element 45 allows only condensate to pass through, thus allowing oil impurities to accumulate inside the separation cylinder 42. This achieves the separation of condensate and oil impurities. When too much oil impurity accumulates, it can be automatically discharged to the outside through pipe 46. Then, the condensate enters the storage tank 13 for further processing. During storage, the filter 32 filters the condensate, and the piezoelectric weight 12 measures the weight of the storage tank 13 to measure the amount of condensate. When there is too much condensate, the condensate input can be stopped to prevent the storage tank 13 from storing too much condensate. When it is necessary to drain the condensate, the impeller pump 22 is turned on to drain the condensate from the storage tank 13. When it is necessary to save the condensate when the machine is stopped, the motor 63 is turned on to drive the agitator 61 to rotate and stir the condensate. The moving condensate can prevent fungi from adhering to the inner wall of the storage tank 13, hindering the reproduction of fungi and thus preventing the condensate from being contaminated by fungi.

[0035] like Figures 1 to 7As shown, this utility model discloses a condensate recovery filtration device. During operation, condensate is first introduced into a hydrocyclone separator 52. The hydrocyclone separator 52 separates solid impurities from the condensate through its own structure. A collection box 51 stores the separated solid impurities. Then, the condensate enters a separation cylinder 42, where a coalescing filter element 44 disperses the condensate and oily impurities, breaking up the emulsified state of the oily impurities and promoting their separation from the condensate. A hydrophilic-oleophobic filter element 45 allows only condensate to pass through, thus allowing oily impurities to accumulate inside the separation cylinder 42. This achieves the separation of condensate and oily impurities. When too much oily impurity accumulates, it can be automatically discharged to the outside through pipe 46. The condensate then enters the storage tank 13 for storage. At the same time, the filter screen 32 filters the condensate, and the piezoelectric weighing block 12 measures the weight of the storage tank 13 to measure the amount of condensate. When there is too much condensate, the condensate input can be stopped to prevent the storage tank 13 from storing too much condensate. When it is necessary to drain the condensate, the impeller pump 22 is turned on, and the impeller pump 22 operates to drain the condensate from the storage tank 13. When it is necessary to save the condensate when the machine is stopped, the motor 63 is turned on. The motor 63 provides power to drive the stirring paddle 61 to rotate and stir the condensate. The moving condensate can prevent fungi from adhering to the inner wall of the storage tank 13, inhibiting fungal reproduction and thus preventing the condensate from being contaminated by fungi.

[0036] The four piezoelectric weight blocks 12, impeller pump 22, coalescing filter element 44, two hydrophilic and oleophobic filter cartridges 45, hydrocyclone separator 52 and motor 63 of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0037] The main functions achieved by this utility model are as follows: by setting up a filter device 03, it is convenient to clean the machine without stopping the machine, thus improving the machine's usability; and by setting up an oil-water separator 04, it separates oily impurities in the condensate, thus improving the machine's recovery effect. This solves the existing technical problems that require manual cleaning of the machine's interior by workers after long-term operation, resulting in poor machine usability, and that existing machines lack the ability to separate and filter oily impurities when condensing steam, leading to poor condensate recovery effect.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
