Problems solved by technology

[0005] The flue gas delivery pipeline in the prior art has the following problems during transportation: 1. Due to the large amount of organic waste gas such as carbon dioxide and sulfur dioxide in the flue gas, when the flue gas is transported, the delivery pipeline will be eroded to a certain extent
2. Due to the high temperature of the boiler flue gas, it will cause thermal expansion and contraction of the transportation pipeline during transportation, resulting in deformation of the transportation pipeline. In severe cases, it will also cause leakage of the transportation pipeline
[0007] The non-metallic compensator in the prior art has the following problems when it is used in the flue gas discharge pipeline of a power plant: 1. Due to the high temperature of the flue gas, the temperature difference between the inside and outside of the pipeline is large, and the water vapor in the flue gas is easily Condensation on the inner wall of the non-metallic compensator, the condensed water is easy to penetrate into the skin and the non-metallic material filled inside the compensator, the service life of the non-metallic compensator will be reduced, and the maintenance cost will increase. When the compensator is repaired and replaced, the entire The exhaust gas conveying system needs to be shut down, which seriously affects the work efficiency; 2. The dust in the flue gas is easy to accumulate dust in the compensator, which affects the compensation amount of the compensator; 3. The temperature of the flue gas is too high, and it is easy to penetrate into the compensator. It poses a safety threat to non-metallic materials. After a long time of use, the sealing performance of the compensator will deteriorate, which cannot meet the needs of the industry.

Abstract

The invention discloses a non-metal compensator for a flue gas conveying pipeline of a power plant boiler. A left connector support, a right connector support, a skin, a flow guiding assembly, a non-metal heat preservation assembly and compression assemblies are included; the two ends of the skin are connected with the left and right connector supports correspondingly through the compression assemblies; the flow guiding assembly comprises a first flow guiding barrel and a second flow guiding barrel which are arranged in a sleeved manner, and an elastic assembly and a waterproof assembly are arranged between the first flow guiding barrel and the second flow guiding barrel; and the space defined by the flow guiding assembly and the skin is filled with the non-metal heat preservation assembly. According to the non-metal compensator for the flue gas conveying pipeline of the power plant boiler, influences of condensed water on the compensator are effectively reduced, the service life of the compensator is prolonged, and the compensation amount of the compensator is increased.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to a non-metallic compensator for a power plant boiler flue gas transmission pipeline. Background technique [0002] Power equipment (power system) mainly includes two categories: power generation equipment and power supply equipment. Transformers, contactors, etc. [0003] With the rapid development of my country's economy, power plant boilers are one of our three major power generation equipment and the basic driving force for my country's economic development. In recent years, with the change of thinking on environmental protection and energy saving, a large number of power station boilers with low energy efficiency and heavy pollution have been shut down. At present, driven by positive factors such as the advancement of environmental protection technology, the reduction of power generation costs, and the increase in power demand, the future development prospects of the ...
