Embodiment 1

[0038] A pipeline flushing device, such as figure 1 As shown, it includes an air supply device, an ice storage tank 2 and a waste water tank 3, the air outlet of the air supply device communicates with the air inlet of the ice storage tank 2, and the outlet of the ice storage tank 2 is connected to the waste water tank through the pipeline 13 to be washed. The inlet of 3 is connected, and the ice storage tank 2 is provided with a feed port for adding dry ice / crushed ice, and the feed port is provided with a first valve 41 for opening / closing the feed port.

[0039] Through the pipeline flushing device with the above structure, when in use, the air supply equipment blows the dry ice / crushed ice in the ice storage tank 2 into the pipeline 13 to be washed, and the crushed ice has a certain hardness, which is equivalent to abrasive, and can effectively The aging product adsorbed on the inner wall of the pipeline 13 to be cleaned can be washed out without causing damage to the inne...

Embodiment 2

[0050] A pipeline flushing method such as figure 1 and figure 2 As shown, use the pipeline flushing device in Embodiment 1 to carry out the following steps:

[0051] Step 1: Connect the pipeline 13 to be washed; connect the oil inlet pipe, the oil return pipe and the safety oil pipe in the oil control device in sequence to form the pipeline 13 to be washed, wherein the oil inlet of the oil inlet pipe becomes the inlet of the pipeline 13 to be washed, The oil outlet of the safety oil pipe becomes the outlet of the pipeline 13 to be washed, and the pipeline 13 to be washed is connected with the pipeline flushing device; the inlet of the pipeline 13 to be washed is also connected with the tee joint C12, and the pipeline to be washed is connected to the tee joint C12. The outlets of 13 communicate with the third valve 43 and the fourth valve 44 respectively, so that when the pipeline flushing device starts, it can be performed by opening / closing the second valve 42, the third va...

Abstract

The invention belongs to the technical field of pipeline flushing, and particularly relates to a pipeline flushing device and method. The pipeline flushing device comprises a gas supplying device, anice storage tank and a waste water tank; a gas outlet of the gas supplying device communicates with a gas inlet of the ice storage tank; an outlet of the ice storage tank communicates with an inlet ofthe waste water tank through a to-be-flushed pipeline; the ice storage tank is provided with a feeding inlet facilitating adding of dry ice / crushed ice; and a first valve used for opening / closing thefeeding inlet is arranged at the feeding inlet. According to the pipeline flushing device, aged objects on the inner side wall of the to-be-flushed pipeline are flushed out through the dry ice / the crushed ice, and the dry ice / the crushed ice is not left in the to-be-flushed pipeline; and the to-be-flushed pipeline is flushed forwards and reversely through the pipeline flushing method provided bythe invention, thus the to-be-flushed pipeline is washed more comprehensively, and the situation that the pipeline flushing device cannot safely and stably operate due to pipeline blockage of an oil control system is avoided.

Description

technical field [0001] The invention belongs to the technical field of pipeline flushing, and in particular relates to a pipeline flushing device and a pipeline flushing method. Background technique [0002] Many existing large-scale equipment need to use oil control systems. For example, there are three oil control systems in steam turbines in power plants, which are the regulation and control oil system, lubricating oil system and generator sealing oil system. The cleanliness of the oil used in them is quite Importantly, the quality of the oil and lubricating oil adjusted in the three oil control systems is directly related to the safe and stable operation of the turbogenerator set. [0003] As the operating cycle of the equipment increases and the oil inside the oil control system will age and decompose under the action of various external comprehensive factors, part of the products in the oil aging process will be intercepted by the filter screen, and the other part will...
