Description

Technical Field

[0001] The utility model relates to the technical field of power wave scrubbers, in particular to a power wave scrubber with a highly visible spray head. Background Art

[0002] The working principle of the dynamic wave scrubber mainly relies on the action of dynamic waves. This equipment is used to wash and separate droplets or particles in gas-liquid mixtures. The purification process of flue gas acid-making industry often adopts dynamic wave scrubbing technology to cool and remove dust from high-temperature flue gas. The high-temperature flue gas and acid collide and fully contact at high speed in the reverse nozzle of the dynamic wave scrubber, completing the gas-liquid mass transfer and heat transfer process, thereby achieving the purpose of cooling and removing dust from the flue gas.

[0003] The spray height of the dynamic wave scrubber nozzle is a key control point. If the spray height is too high, it will cause acid corrosion of the carbon steel pipe on the upper part of the dynamic wave overflow weir. If the spray height is too low, the lower fiberglass pipe will be damaged by high-level flue gas. The spray height will change due to various factors. The existing dynamic wave spray height control measures are mainly to control the nozzle pressure and remove the manhole to check the spray height. When removing the manhole, the negative pressure environment in the reverse nozzle is destroyed, which is different from the actual working state of the spray, resulting in inaccurate spray height control and waste of labor. Utility Model Content

[0004] The main purpose of the utility model is to provide a dynamic wave scrubber with visible spray height of the nozzle, so as to solve the problems of inaccurate spray height control and waste of labor in the above-mentioned prior art dynamic wave scrubber.

[0006] Furthermore, the camera is fixedly connected to a support rod, and the camera is located at the end of the support rod; the support rod is plugged into the observation tube.

[0007] Furthermore, a stepped hole is provided inside the observation tube, the stepped hole includes an inner conical hole and an outer cylindrical hole, a sealing gasket is provided inside the cylindrical hole; the end of the support rod is provided with a conical head and a cylindrical head matching the stepped hole.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1 to Figure 2 As shown, a dynamic wave scrubber with visible spray height of the nozzle comprises a dynamic wave cylinder 1, the dynamic wave cylinder 1 is connected to a reverse spray pipe 2, the reverse spray pipe 2 is connected to an overflow weir 3, a dynamic wave nozzle 8 is arranged in the reverse spray pipe 2, an observation tube 4 is connected to the position above the overflow weir 3 on the reverse spray pipe 2, a valve 5 is arranged on the observation tube 4, a movable camera 6 is arranged on one side of the observation tube 4, which can be inserted into the reverse spray pipe 2 along the observation tube 4 to observe the spray height, and the camera 6 is communicatively connected to the computer in the DCS main control room.

[0027] The camera 6 is fixedly connected to the support rod 7, the camera 6 is located at the end of the support rod 7, and the wire of the camera 6 is arranged inside the support rod 7; the support rod 7 is plugged into the observation tube 4; a stepped hole is arranged inside the observation tube 4, the stepped hole includes an inner conical hole and an outer cylindrical hole, and a sealing gasket 13 is arranged on the inner side of the cylindrical hole; a conical head 701 and a cylindrical head 702 matching with the stepped hole are arranged at the end of the support rod 7; when the support rod 7 is plugged into the observation tube 4, the sealing between the support rod 7 and the observation tube 4 is achieved under the cooperation of the conical hole and the conical head 701 and the extrusion of the cylindrical head 702 and the sealing gasket 13.

[0028] The support rod 7 is connected with an air blowing pipe 703 for blowing air to the camera, and the pipeline of the air blowing pipe 703 is arranged inside the support rod 7; the air blowing pipe 703 can cool down the camera and blow away dust, so that the camera can take clear pictures and transmit the pictures to the computer in the DCS control room.

[0029] The support rod 7 is fixedly connected to a power mechanism 10 that drives the support rod 7 to reciprocate; the power mechanism 10 is a cylinder, a hydraulic cylinder or an electric push rod, etc.; the support rod 7 is fixedly connected to a support bracket 11, a slide rail 12 is provided under the support rod 7, and the support bracket 11 is slidably connected to the slide rail 12; the support bracket 11 and the slide rail 12 ensure the stability of the support rod when it moves.

[0030] Example 2

[0031] like Figure 3As shown, Example 2 also provides a dynamic wave scrubber with highly visible nozzle spraying liquid.

[0032] The working principle of the above embodiment is:

[0033] When the water supply pump current of the power wave nozzle 8 fluctuates and the pressure and flow rate of the water supply pipe fluctuate, it means that the spray height of the power wave nozzle 8 may change, and it is necessary to check the spray height of the power wave nozzle 8 in the reverse spray pipe 2; first open the valve 5, then the camera 6 is pushed into the reverse spray pipe 2 under the action of the support rod 7, and finally the camera 6 transmits the picture to the computer in the DCS main control room, so as to directly obtain the spray height; when the spray height is not appropriate, adjust the spray height to a suitable range; this method of adjusting the spray height is more convenient and more accurate.
