Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of condenser cleaning, and particularly relates to a condenser integrated robot integrated cleaning device. BACKGROUND

[0002] The steam turbine unit of a waste incineration power plant is an important equipment system for converting steam energy into mechanical energy, and the condenser is an important component of the condensing steam turbine unit. The condenser is a heat exchanger for condensing the exhaust steam of the steam turbine into water. The working performance of the condenser directly affects the thermal economy of the entire waste incineration power plant unit.

[0003] In actual operation, the condenser heat exchange efficiency will inevitably decrease due to various reasons. The condenser of the power plant is a key component in the open cycle cooling system, and is prone to scaling and corrosion. The scaling will increase the resistance of the cooling water to some extent, reducing its flow rate. On the other hand, due to the relatively small thermal conductivity of the scale, the heat transfer coefficient of the equipment is reduced, which adversely affects the normal heat exchange. After the condenser cooling water pipe is scaled, a robot transfer device is used to drive a high-pressure water gun to move and achieve internal flushing of the condenser cooling water pipe.

[0044] In an optional embodiment, a plurality of support rods 234 are symmetrically fixedly connected to the surface of the water injection pipe 232. The support rods 234 are located inside the conveying circular groove 233, and the end of the support rod 234 away from the water injection pipe 232 is fixedly connected to the movable housing 221.

[0045] It should be noted that the first mounting slot 2110 is also equipped with a signal receiving device, a signal transmitting device, and a motor control circuit. The motor control circuit is connected to the signal receiving device. The signal receiving device is used to receive the position information sent by the signal transmitting device, determine the distance between the cleaning device and the robot transfer device, and send the determined distance to the control circuit. The control circuit controls the start and stop of the first motor 212 and the second motor 2213 according to the received distance value, thereby determining whether to move and whether to clean. This invention achieves intelligent cleaning of cooling water pipes of different lengths by using the signal transmitting device and the signal receiving device in conjunction.

[0046] Working principle: When the device is in use, the cleaning device is moved by a robot transfer device, thereby inserting the cleaning device into the condenser cooling water pipe. After the cleaning is completed, the cleaning device is transferred by the robot transfer device to another condenser cooling water pipe for cleaning. Due to the material characteristics of the conveying sleeve 231 and the water injection pipe 232, the conveying sleeve 231 and the water injection pipe 232 can be bent. The end of the conveying sleeve 231 away from the moving housing 221 is inserted into the waste collection box, and the end of the water injection pipe 232 away from the cleaning housing 1 is connected to the high-pressure water pump. When the device is placed in the condenser cooling water pipe, the operation of the first motor 212 drives the scraper head 214 through the first rotating shaft 216. The rotation of the scraper head 214 drives the spiral cutting blade 215 to rotate within the condenser cooling water pipes. The rotation of the spiral cutting blade 215 breaks down the scale in the condenser cooling water pipes, and its spiral shape provides some forward propulsion. Furthermore, the rotation process removes larger, harder scale. As the cleaning housing 1 moves within the condenser cooling water pipes, the broken scale is transported towards the cleaning housing 1 by the spiral cutting blade 215, and further broken down by the transverse cutting blade 211, which further breaks down the scale adhering to the inside of the condenser cooling water pipes. This facilitates the breaking down of scale in the condenser cooling water pipes, preventing the device from becoming immobile due to hard scale. When the device is moved inside the condenser cooling water pipe, due to the elastic potential energy of the spring 226, when the device is placed in the condenser cooling water pipe, both the second roller 2210 and the first roller 225 are in contact with the inner wall of the condenser cooling water pipe, and there is a corresponding force between them, causing the second motor 2213 to run. After the second motor 2213 runs, it drives the second gear 2212 to rotate. The rotation of the second gear 2212 drives the first gear 2211 to rotate. The first gear 2211 drives the second roller 2210 to rotate through the second rotating shaft 229. When the second roller 2210 rotates, it can move the device in the condenser cooling water pipe, which is beneficial for moving the device inside the condenser cooling water pipe and improving the cleaning efficiency. The device works as follows: When the high-pressure water pump is running, water is injected into the water storage tank 237 along the water injection pipe 232, and then sprayed out along the first water distribution tank 238 and the second water distribution tank 239. Because the first water distribution tank 238 and the second water distribution tank 239 are arranged in a staggered, ring-shaped array, the water inside the water storage tank 237 is sprayed at high pressure onto the condenser cooling water pipes without any dead angles. During the movement of the device, the spiral cutting blade 215 and the transverse cutting blade 211 break up the dirt on the inner wall of the condenser cooling water pipes. The high-pressure water sprayed from the water storage tank 237 onto the dirt washes away most of it, while also wetting the small amount of dirt still adhering to the inner wall of the condenser cooling water pipes. As the device moves...The annular collecting hood 235 scrapes away the dirt adhering to the inner wall of the condenser cooling water pipes. As the annular collecting hood 235 moves, the dirt flows along its interior into the conveying trough 233, then along the conveying sleeve 231, and finally into the waste collection box. This process helps to break up the dirt on the inner wall of the condenser cooling water pipes, and most of the dirt is washed away by water spraying. Simultaneously, it wets the small amount of dirt still adhering to the inner wall of the condenser cooling water pipes before scraping it off.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
