[0007] Further, the condensing pipe is inclined, and the height of the water inlet pipe is lower than the height of the water outlet pipe.

[0008] Further, the water supply and drainage device includes a water pump, a water supply pipe connected to the water pump, and a drain pipe; the water supply pipe is connected to the water inlet pipe, and the drain pipe is connected to the water outlet pipe.

[0009] Further, one side of the hood body is provided with a water inlet hole and a water outlet hole; the water inlet hole is arranged close to the water inlet pipe, and the water outlet hole is arranged close to the water outlet pipe; the water supply pipe passes through the water inlet hole and is detachably connected to the water inlet pipe, and the drain pipe passes through the water outlet hole and is detachably connected to the water outlet pipe.

[0010] Further, the clamping groove includes a first clamping groove for accommodating the water inlet pipe and a second clamping groove for accommodating the water outlet pipe; the opening side of the first clamping groove faces the second clamping groove, and the opening side of the second clamping groove faces the first clamping groove.

Detailed implementation manners

[0022] Embodiment

[0023] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 6 As shown, the condensing oil fume hood of this embodiment includes a horizontally arranged and hollow hood body 11, an air outlet 13 opened at the upper end of the hood body 11, an air inlet 12 opened at the lower end of the hood body 11, a condensing component 20 arranged at the air inlet 12, and a water supply and drainage device connected to the condensing component 20; U-shaped card slots are provided on both sides opposite to the air inlet 12, and both sides of the condensing component 20 are respectively clamped in the card slots. Specifically, an external exhaust fan needs to be matched during use, so that air enters the hood body 11 through the air inlet 12 and then is discharged from the air outlet 13 (after being discharged from the air outlet 13, it will enter the corresponding pipeline). When the air containing oil fume passes through the air inlet 12, it will contact the condensing component 20 at the air inlet 12. High-temperature particles such as oil fume will be cooled by the condensing component 20, and the cooled oil and water will adhere to the condensing component 20 and flow along the condensing component 20 into the card slots and the hood body 11, and be collected in the hood body 11 (or directly discharged). In this way, when inhaling the oil fume air, the oil fume air is cooled immediately for the first time, and part of the oil and water in it are removed, which can reduce the pressure of the subsequent treatment equipment to a certain extent and improve the treatment efficiency of the oil fume air.

[0024] In this embodiment, the condensation assembly 20 includes a water inlet pipe 21 and a water outlet pipe 22 arranged in parallel, and a plurality of condensation pipes 23 for connecting the water inlet pipe 21 and the water outlet pipe 22; the water inlet pipe 21 and the water outlet pipe 22 are respectively clamped in the card slots; the plurality of condensation pipes 23 are distributed along the length direction of the water inlet pipe 21, and the length direction of the condensation pipe 23 is perpendicular to the length direction of the water inlet pipe 21. The condensation pipe 23 is inclined, and the height of the water inlet pipe 21 is lower than the height of the water outlet pipe 22. The water supply and drainage device includes a water pump, a water supply pipe 18 connected to the water pump, and a drainage pipe 19; the water supply pipe 18 is connected to the water inlet pipe 21, and the drainage pipe 19 is connected to the water outlet pipe 22. Specifically, the water pump sends normal temperature water or cold water into the water inlet pipe 21 through the water supply pipe 18, and after flowing through the condensation pipe 23, it is discharged from the water outlet pipe 22 and the drainage pipe 19. The lower height of the water inlet pipe 21 is more conducive to the water in the condensation pipe 23 fully filling the condensation pipe 23.

[0025] One side of the cover body 11 in this embodiment is provided with a water inlet hole and a water outlet hole; the water inlet hole is arranged close to the water inlet pipe 21, and the water outlet hole is arranged close to the water outlet pipe 22; the water supply pipe 18 is detachably connected to the water inlet pipe 21 after passing through the water inlet hole, and the drainage pipe 19 is detachably connected to the water outlet pipe 22 after passing through the water outlet hole. Specifically, the condensation assembly 20 can be first clamped into the card slot, and then the water supply pipe 18 and the drainage pipe 19 are connected. When disassembling, the water supply pipe 18 and the drainage pipe 19 are first removed, and then the condensation assembly 20 can be taken out for cleaning.

[0026] The card slot in this embodiment includes a first card slot 14 for accommodating the water inlet pipe 21 and a second card slot 15 for accommodating the water outlet pipe 22; the opening side of the first card slot 14 faces the second card slot 15, and the opening side of the second card slot 15 faces the first card slot 14. A plurality of first springs 16 are arranged in the first card slot 14, and a plurality of second springs 17 are arranged in the second card slot 15; the axis of the first spring 16 is perpendicular to the length direction of the water inlet pipe 21, and the axis of the second spring 17 is perpendicular to the length direction of the water outlet pipe 22. Specifically, when installing the condensation assembly 20, the water inlet pipe 21 can be first clamped into the first card slot 14 and the first spring 16 is compressed, and then the water outlet pipe 22 is clamped into the second card slot 15. In this way, both sides of the condensation assembly 20 are supported by the first spring 16 and the second spring 17. During the operation of the system, due to the vibration of the fan and the flow of air, the condensation assembly 20 will be driven to vibrate, and this vibration can prompt the oil, water, etc. adhering to the condensation pipe 23 to flow downward faster.

[0027] A plurality of oil discharge holes are provided on the lower side wall of the first card slot 14 in this embodiment. Specifically, the oil on the condensation pipe 23 can enter the cover body 11 through the oil discharge holes for temporary storage or direct discharge.

[0028] In summary, the condensing oil fume hood of this embodiment needs to be used in conjunction with an external exhaust fan during operation. Air enters the hood body 11 through the air inlet 12 and then is discharged from the air outlet 13 (after being discharged from the air outlet 13, it will enter the corresponding pipeline). When the air containing oil fume passes through the air inlet 12, it will come into contact with the condensing component 20 at the air inlet 12. High-temperature particles such as oil fume will be cooled by the condensing component 20. The cooled oil and water will adhere to the condensing component 20 and flow along the condensing component 20 into the card slot and the hood body 11, where they are collected (or can be directly discharged). In this way, when inhaling the oil fume air, the oil fume air is cooled immediately, and part of the oil and water in it are removed, which can reduce the pressure on the subsequent treatment equipment to a certain extent and improve the treatment efficiency of the oil fume air.
