A turbine equipped with a cleaning device for cooking dynamic and static blades

Abstract

The invention discloses a turbine equipped with a cleaning device for cooking dynamic and static blades, which comprises a gas cut-off valve A, an outer casing of the turbine, a gas exhaust port of the turbine, a gas cut-off valve B, a gas outlet pipe, a steam inlet Gas pipeline, steam shut-off valve and blowdown valve, the two ends of the turbine outer casing are respectively provided with a turbine gas inlet pipe port and a turbine gas exhaust port, and the sides of the turbine gas inlet pipe port A steam inlet pipe is connected, a steam shut-off valve is arranged on the steam inlet pipe, and a blowdown valve is connected to an opening on the side of the gas exhaust port of the turbine. The invention cleans the turbine by steaming and boiling, which saves labor, time and cost, not only eliminates hidden dangers of the equipment, but also makes an annual profit of 2 million yuan.

Description

technical field [0001] The invention relates to a turbine, in particular to a turbine equipped with a cleaning device for cooking dynamic and static blades. Background technique [0002] In order to maximize profits, make full use of energy, and save electricity costs, most metallurgical ironmaking industries use BPRT air supply systems or TRT systems to make full use of a large amount of gas with pressure energy and heat energy generated by blast furnaces, and generate mechanical energy through turbine expansion. Then through the speed-up clutch direct fan or direct generator. After expansion, the low-energy gas is connected to the grid and sent to the gas-fired boiler to mix with air for combustion. The boiler generates steam to drive the steam turbine generator set to generate electricity, or the steam turbine is directly connected to the sintering exhaust fan through the clutch reducer. Or send steam into the user for heating and heating. Adopting this method is not on...

Problems solved by technology

Although the dust content of blast furnace gas is controlled within the required range, the saturated water content in the gas is very high. After the gas undergoes primary expansion and work, the temperature of the gas drops significantly, and a large amount of gas condensate is produced, which mixes with the dust in the gas to produce mud. When the secondary blade is pushed to do work, the mud is easy to stick to the blade. Due to the strong driving force, the adhesion is very strong and it is difficult to get rid of it. Although some equipment has its own soft water spray system, the effect is not good, resulting in secondary The thickness of the dirt adhered to the blade pushing surface is uneven, and the vibration of the turbine rotor increases. To ensure safe operation, it must be shut down regularly, and the upper cover and bearing cylinder must be removed; the rotor is transported to the factory for high-speed dynamic balancing, otherwise the rotor vibration exceeds the limit requirement 8 When the road is on the road, there will be a vicious safety accident that destroys the plane and kills people, and the economic and social reputation effects will cause two major losses
