Description

Technical Field

[0001] This utility model relates to the field of duct silencing technology, and in particular to a silencing device for waterproof condensation ventilation ducts. Background Technology

[0002] The air flowing inside ventilation ducts (such as fire escape exhaust ducts) contains a certain amount of moisture. When the surface temperature of the duct is lower than the dew point temperature (or the temperature difference is too large), the water vapor in the air will quickly condense into liquid water, forming condensation. This will not only make the duct surface wet, but may also form a water film, affecting the smoothness of airflow and thus generating additional noise.

[0003] Therefore, we propose a silencer for waterproof condensate ventilation ducts. Utility Model Content

[0004] In view of this, the present invention provides a water-resistant condensation ventilation duct silencer to solve the problem in the prior art that when the ventilation temperature difference is too large, water vapor will easily condense inside the duct, increasing noise.

[0005] A silencer for a waterproof condensation ventilation duct includes a venturi tube, and a condensation mechanism is installed inside the venturi tube. The condensation mechanism includes a rotating shaft rotatably installed inside the venturi tube, and a fan blade is fixedly installed at one end of the rotating shaft, with the fan blade located inside the narrow diameter section of the venturi tube.

[0006] A turbine fan is fixedly installed inside the venturi tube, and the other end of the rotating shaft is fixedly connected to the drive shaft of the turbine fan.

[0007] The air inlet and outlet of the turbine fan are respectively connected to a row of copper pipes through pipes. The upper and lower ends of the copper pipes pass through the side wall of the venturi tube and are connected to the outside of the venturi tube. A water storage chamber is fixedly connected to the bottom of the air outlet section of the venturi tube.

[0008] Preferably, the air outlet section of the venturi tube described above has a through hole A communicating with the copper tube, and the outer surface of the copper tube is smooth.

[0009] Preferably, the above also includes an insulating sleeve, which is fitted over the outside of the Venturi tube, and an asbestos layer is filled between the insulating sleeve and the Venturi tube.

[0010] Preferably, the aforementioned insulation sleeve is installed through the wall, with the air inlet section of the Venturi tube located indoors and the air outlet section of the Venturi tube located outdoors.

[0011] Preferably, the above-mentioned insulation sleeve is provided with a through hole B aligned with the through hole A, and a baffle is also fixedly sleeved on the insulation sleeve between the two sets of through holes B.

[0012] Preferably, a valve is installed at the lower end of the aforementioned water storage chamber.

[0013] Preferably, the valve described above has a piston chamber inside, a piston block is slidably installed inside the piston chamber, a spring is fixedly installed at the bottom of the piston chamber, the upper end of the spring is fixedly connected to the bottom of the piston block, and a drain port communicating with the inside of the piston chamber is opened on the lower part of the side wall of the valve.

[0014] Preferably, the aforementioned rotating shaft is rotatably mounted inside the venturi tube via a support rod and bearings.

[0015] Preferably, a water-blocking strip is fixedly connected to the bottom inner wall of the venturi tube described above.

[0016] Preferably, a conical body is fixedly mounted on the aforementioned rotating shaft, and the top of the conical body is aligned with the center of the narrow diameter portion of the venturi tube.

[0017] Implementing the embodiments of this utility model will have the following beneficial effects:

[0018] The aforementioned waterproof condensate ventilation duct silencer was adopted.

[0019] Through the design of the Venturi tube, the Venturi tube generates a turbulence effect when gas passes through, which can reduce the transmission of external noise into the room.

[0020] The condensation mechanism introduces cold air from outside into the copper pipe to cool the exhaust pipe. The airflow inside the copper pipe and the Venturi tube comes into contact with each other, which can cool and condense the air. Condensation can reduce the moisture in the exhaust gas, and cooling can reduce the temperature difference between the exhaust airflow and the inner wall of the subsequent exhaust duct, thereby preventing condensation from occurring in the duct.

[0021] A fan is installed inside the narrow section of the venturi tube. The narrow section can accelerate the airflow and use the accelerated airflow to drive the fan, which in turn drives the turbine fan and draws in cold air from the outside into the copper tube. No additional power is required, which is very convenient.

[0022] The water storage chamber and valves allow for the collection of condensed water and drainage, which is very convenient. Attached Figure Description

The condensation mechanism 500 includes a rotating shaft 501 rotatably mounted inside the Venturi tube 200. The rotating shaft 501 is rotatably mounted inside the Venturi tube 200 via a support rod 507 and a bearing 506. A fan blade 502 is fixedly mounted at one end of the rotating shaft 501, and the fan blade 502 is located at the narrowest part 2 of the Venturi tube 200. 02. Inside; a turbine fan 508 is fixedly installed inside the venturi tube 200, and the other end of the rotating shaft 501 is fixedly connected to the drive shaft of the turbine fan 508; the air inlet and air outlet of the turbine fan 508 are respectively connected to a row of copper pipes 505 through pipes, and the upper and lower ends of the copper pipes 505 pass through the side wall of the venturi tube 200 and communicate with the outside of the venturi tube 200; a water storage chamber 300 is fixedly connected to the bottom of the air outlet section 203 of the venturi tube 200.

[0036] In implementation, such as Figure 2 As shown, the surface of the air outlet section 203 of the venturi tube 200 is provided with a through hole A204 that communicates with the copper tube 505, and the outer surface of the copper tube 505 is smooth.

[0037] Specifically, such as Figure 1 The system also includes an insulation sleeve 100, which is fitted over the Venturi tube 200, with an asbestos layer filling the space between the insulation sleeve 100 and the Venturi tube 200. The asbestos layer provides noise reduction and insulation; the insulation sleeve 100 is made of insulating rubber and plastic material. In use, the insulation sleeve 100 is installed through the wall, with the air inlet section 201 of the Venturi tube 200 located indoors and the air outlet section 203 of the Venturi tube 200 located outdoors.

[0038] In implementation, such as Figure 3 As shown, a water-blocking strip 504 is fixedly connected to the inner side wall of the bottom of the Venturi tube 200. The water-blocking strip 504 can prevent condensed water from flowing into the subsequent air duct.

[0039] In practice, a conical body 503 is fixedly mounted on the rotating shaft 501, with the top of the conical body 503 aligned with the center of the narrow diameter portion 202 of the venturi tube 200. The conical body 503 disperses the airflow.

[0044] The valve 400 above is designed as a pressure relief valve. When there is enough water in the water storage chamber 300, it can automatically press down the spring 403 under the action of gravity and discharge the water from the drain outlet 402 without the need for manual drainage, which is more convenient.
