Description

Technical Field

[0001] The utility model relates to the technical field of boiler water treatment, in particular to a water treatment device for desalting boiler water. Background Art

[0002] Boiler water can be roughly divided into: raw water, feed water, make-up water, boiler water, sewage, condensate, etc. In the water treatment process, water containing hardness is called hard water; water that has been treated with nano-ion exchange to remove hardness is called soft water; water that has been treated with anion and cation exchange to remove salt substances is called demineralized water.

[0003] Wastewater is generated in the production of desalted water, and the wastewater also contains salt substances. In the existing treatment of salt in the wastewater, the wastewater is evaporated and placed in an evaporation box frame. The wastewater is heated and evaporated to make salt crystals remain on the evaporation box frame, and then the evaporated gas is collected through a suction pipe and condensed into liquid again to separate the salt in the wastewater. However, in the evaporation process, multiple evaporation plates are placed to increase efficiency. In the prior art, when the wastewater is placed in multiple evaporation plates, it is necessary to perform water discharge treatment individually, which is a relatively cumbersome method. Therefore, a water treatment device for desalination of boiler water is proposed. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-4 , which is an embodiment of the utility model, provides a water treatment device for desalination of boiler water. The water treatment device for desalination of boiler water comprises a treatment box 1 and a liquid supply pipe 2. The bottom surface of the liquid supply pipe 2 is fixedly connected to the upper surface of the treatment box 1. An evaporation heating structure connected to the interior is installed on the back of the treatment box 1. An exhaust pipe is installed on the upper surface of the treatment box 1 to exhaust the evaporated steam for subsequent condensation. Four vertical rods 3 are fixedly inserted in the interior of the treatment box 1. An evaporation box frame 4 is arranged on the inner side of the treatment box 1. The number of evaporation box frames 4 is arranged in plurality, and the plurality of evaporation box frames 4 are equidistantly distributed. A salt support pan 12 is slidably inserted in the interior of the evaporation box frame 4. The middle part of the upper surface of the salt support pan 12 is a semi-annular structure. After the wastewater evaporates, the salt remains on the upper surface of the salt support pan 12. The salt can be taken out by pulling the salt support pan 12 out of the evaporation box frame 4. 4 is slidably sleeved on the outer surfaces of the four vertical rods 3, and the bottom surface of the evaporation box frame 4 is fixedly connected with four support springs 5. The vertical rod 3 is located on the inner ring side of the support spring 5, and the lower end of the support spring 5 is fixedly connected with a support ring 6. The upper surface of the support ring 6 is fixedly connected with a height-fixing rod 17, which is arranged in parallel with the vertical rod 3. The height-fixing rod 17 limits the maximum distance of the evaporation box frame 4 moving downward to prevent the support spring 5 from being crushed. The support ring 6 is fixedly sleeved on the outer surface of the vertical rod 3. The front and back sides and the left and right sides of the evaporation box frame 4 are all provided with liquid outlet grooves 7. The upper end of the evaporation box frame 4 is fixedly sleeved with a water collecting frame 13, and the water collecting frame 13 collects the liquid flowing down from the top of the evaporation box frame 4. The left and right sides and the front and back sides of the evaporation box frame 4 are fixedly connected with a guide frame 14, and the guide frame 14 is connected with the liquid outlet groove 7, so that the overflowed waste water has a tendency to flow to the center of the evaporation box frame 4.

[0026] A turntable 8 is provided in front of the liquid supply pipe 2, and a curved pipe 9 is provided in front of the turntable 8. The other end of the curved pipe 9 is fixedly inserted through the upper surface of the processing box 1. A long shaft 10 is fixedly inserted at the axis of the turntable 8. The long shaft 10 is rotatably connected to the processing box 1. A through hole 11 is provided on the disk surface of the turntable 8. A positioning arc plate 18 is fixedly installed on the front of the turntable 8 and located at the upper end of the curved pipe 9. The front end of the liquid supply pipe 2 is coaxially arranged with the rear end of the curved pipe 9. When the positioning arc plate 18 contacts the curved pipe 9, the through hole 11 is stably connected to the liquid supply pipe 2 and the curved pipe 9. The long shaft 11 is fixedly connected to the processing box 1. 0 is fixedly connected with a cross bar 15 on the outer circumferential side surface, and a hook rod 16 is arranged in front of the cross bar 15, and the lower end of the hook rod 16 slides through the upper surface of the processing box 1, and the lower end of the hook rod 16 is fixedly connected with the back of the evaporation box frame 4 located at the bottom, and the upper end of the hook rod 16 is bent backward, and the backward bent part of the hook rod 16 is located above the cross bar 15. When the bottom evaporation box frame 4 is full of water, the cross bar 15 is pulled downward by the hook rod 16, driving the through hole 11 to gradually misalign with the liquid supply pipe 2 and the bent pipe 9, so that the turntable 8 blocks the liquid supply pipe 2.

[0027] During use, when it is necessary to treat waste water, the turntable 8 is rotated to connect the through hole 11 with the liquid supply pipe 2, and the liquid supply pipe 2 adds waste water to the uppermost evaporation box frame 4 through the through hole 11 and the bent pipe 9. When there is enough waste water in the uppermost evaporation box frame 4, the waste water flows out from the liquid outlet 7, and then flows to the top of the next evaporation box frame 4 through the guide frame 14. During the continuous addition of waste water, it is ensured that each evaporation box frame 4 is added with sufficient waste water. When the lowermost evaporation box frame 4 is filled with water, as the waste water in the evaporation box frame 4 increases, the support spring 5 below is compressed, and at the same time, the cross bar 15 is pulled downward through the hook rod 16, so that the through hole 11 is gradually misaligned with the liquid supply pipe 2 and the bent pipe 9, so that the turntable 8 blocks the liquid supply pipe 2, and ensures that after the lowermost evaporation box frame 4 is full of waste water, the liquid supply pipe 2 stops supplying waste water to the bent pipe 9.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
