Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of condenser cleaning, and particularly relates to a scale prevention device for a condenser in a steam turbine generator set. Background Art
[0002] A condenser is a heat exchanger that condenses the exhaust steam of a steam turbine into water, also known as a condensate recuperator. Condensers are mainly used in steam turbine power plants and are divided into two types: water-cooled condensers and air-cooled condensers.
[0003] Since the condenser is in an open state, it is easily affected by the outside world, resulting in the accumulation of microorganisms and sediments. These contaminations will cause the condenser to reduce efficiency and shorten its service life.
[0004] Currently, chemical cleaning or a rubber ball cleaning system is mostly used to clean the pipelines inside the condenser.
[0005] However, chemical cleaning is likely to cause environmental pollution, and the rubber ball cleaning system has a high usage cost. Moreover, relying solely on the water flow to drive the rubber balls into the condenser pipelines for cleaning, the effect is not ideal, and stubborn stains inside the pipelines cannot be cleaned.
[0006] In view of this, the utility model provides a scale prevention device for a condenser in a steam turbine generator set to solve the problem of condenser cleaning. Content of the Utility Model
[0007] The purpose of the utility model is to provide a scale prevention device for a condenser in a steam turbine generator set, aiming to solve the problem of efficient cleaning of stains inside the condenser pipelines in the prior art.

The surface of the brush head is provided with bristles. A water channel is opened inside the brush head. Drainage holes communicating with the water channel are opened on the surface of the brush head. A connector is also provided at the open end of the water channel. A connecting hose penetrates through the inside of the rod portion, and one end of the connecting hose is connected to the connector.
[0009] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the utility model, threaded joints are provided at both ends of the connecting hose, and the connecting hose is threadedly connected to the connector through the threaded joints.
[0010] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the utility model, an anti-slip pad is sleeved outside the rod portion.
[0011] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the present utility model, the anti-slip mat surface is provided with anti-slip lines.

[0013] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the present utility model, the telescopic joint is a hollow tubular structure, and adjacent telescopic joints are sequentially sleeved and threadedly connected.
[0014] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the present utility model, the telescopic joint is a hollow frustum-shaped structure, and adjacent telescopic joints are sequentially sleeved.
[0015] Preferably, as a scale prevention device for a condenser in a steam turbine generator set of the present utility model, when adjacent telescopic joints are stretched, an interference fit connection can be formed.
[0016] Compared with the prior art, the beneficial effects of the present utility model are:
[0017] 1. By adopting high-pressure water flushing and cooperating with the brushing of the brush bristles, when the brush head extends into the pipeline in the condenser, the stains in the pipeline can be well flushed and brushed.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Embodiment 1: Please refer to Figure 1 , Figure 4 , the present utility model provides the following technical solutions: A scale prevention device for a condenser in a steam turbine generator set includes a brush head 1 and a rod part 2 connected to one end of the brush head 1. The surface of the brush head 1 is provided with bristles 5. The bristles 5 can be made of fiber materials or natural wool materials, such as nylon, PET, pig bristles, etc. A water channel 6 is opened inside the brush head 1, and a drain hole 7 communicating with the water channel 6 is opened on the surface of the brush head 1. The drain holes 7 in this embodiment are arranged in an annular and equally spaced manner, and their specific arrangement or setting position can be adaptively produced according to actual needs. A connecting head 8 is also provided at the open end of the water channel 6. A connecting hose 4 penetrates through the inside of the rod part 2. The connecting hose 4 is the same as the hose used in an existing household shower head, and threaded joints are provided at both ends. The connecting hose 4 is threadedly connected to the connecting head 8 through the threaded joints. Here, it should be particularly noted that when the connecting hose 4 is threadedly connected to the connecting head 8, a sealing ring needs to be padded at the connection between the connecting hose 4 and the connecting head 8, or a raw material tape needs to be tied on the threaded connection surface between the connecting hose 4 and the connecting head 8 to prevent water leakage;
[0028] During specific use: Connect the other end of the connecting hose 4 to a booster pump and connect to a water source. Press high-pressure water into the connecting hose 4 and the water channel 6 through the booster pump, and spray it out from the drain hole 7 at high pressure. The cleaning personnel hold the rod part 2 and insert the brush head 1 into the pipeline in the condenser for double cleaning of high-pressure flushing and the brush to prevent the formation of stains on the pipeline in the condenser.
[0029] Furthermore, an anti-slip pad 3 can be sleeved outside the rod part 2. The anti-slip pad 3 is made of materials such as rubber and silicone to improve the anti-slip effect when holding; at the same time, anti-slip patterns can also be provided on the surface of the anti-slip pad 3 to further improve the anti-slip effect when holding.
[0030] Embodiment 2: The difference from the first embodiment is that the rod part 2 does not have a fixed size, but is composed of several telescopic joints of hollow tubular structures, and adjacent telescopic joints are sleeved and threadedly connected in sequence, as Figure 2 - Figure 3 shown;
[0031] During specific use: By rotating adjacent telescopic joints, the adjacent telescopic joints can be telescoped, so that the length of the entire rod part 2 can be adjusted, so as to perform adaptive telescoping according to the actual length of the condenser pipeline, so as to better clean the pipeline in the condenser.
[0032] Embodiment 3: In addition to the threaded telescopic method in Embodiment 2, the telescopic joints of the rod part 2 can also adopt a hollow frustum structure, and adjacent telescopic joints are sleeved in sequence;
[0033] When in use, when stretching between adjacent telescopic joints, due to its frustum structure, an interference fit connection can be formed between the telescopic joints to achieve locking, as Figure 5 shown;
[0034] It should be specifically noted here that the number of telescopic joints in Embodiment 2 and Embodiment 3 is not limited to the number in the drawings, but can be adaptively produced in terms of quantity and size according to the actual required length.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
