Three-way door for adjusting boiler air heater of thermal power plant

Abstract

The invention relates to the technical field of boiler pipelines, and discloses a three-way door for adjusting a boiler air heater of a thermal power plant. The three-way door comprises a fixed tank, wherein the outer side face of the fixed tank fixedly communicates with communicating pipes at equal angles, and a baffle is movably arranged in the fixed tank; an equipment tank is fixedly arranged at the bottom end of the fixed tank; and a motor is fixedly arranged on one side of the bottom end of the inner chamber of the equipment tank. According to the three-way door for adjusting the boiler air heater of the thermal power plant, the baffle is movably arranged, and the baffle is triangular; in winter, a driving gear can be driven to rotate by starting the motor, and the driving gear is controlled to rotate by one turn; at the moment, the gear ratio of the driving gear to a driven gear is one to three, so the driven gear rotates a third of the turn and drives the baffle to rotate to open a warm air pipeline; and on the contrary, in summer, the baffle is controlled to rotate to open a normal pipeline, so that the power consumption of the air heater is reduced, and the advantage of energy conservation is realized.

Description

technical field [0001] The invention relates to the technical field of boiler pipes, in particular to a three-way door for adjusting boiler heaters in thermal power plants. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. Due to the shortage of fossil fuels on the earth, human beings are trying their best to develop nuclear power generation, nuclear fusion power generation and high-efficiency solar power generation, in order to finally solve the energy problems faced by human society. The earliest thermal power generation was realized in 1875 at the thermal power plant at the Gare du Nord in Paris. With the improvement of generator and steam turbine manufacturing technology, the improvement of power transmission and transformation technology, especially the emergence of power system and the demand ...

AI Technical Summary

Problems solved by technology

[0003] Boiler heaters are often used in thermal power plants to achieve heating operations. In order to prevent low-temperature corrosion of the air preheater in winter, northern power plants generally install heaters at the fan inlets to increase the temperature of fan inlets. In summer, the heaters Outage, but due to the muffler-heater-fan structure, due to the existence of the heater, the resistance of the fan is increased in spring, summer and autumn, which increases the power consumption of the boiler fan

[0004] During the installation process of the pipeline, it is necessary to extract the external air to provide the air intake, but the external air contains a lot of dust in the haze weather, so the air entering the pipeline contains a lot of dust and will stick to the baffle at this time. If the surface of the baffle is not cleaned at this time, the dust on the surface of the baffle will enter the interior of the device and cause irreversible effects

[0005] When the external air enters the pipeline through the fan, it will cause the pipeline to vibrate, but the device currently used has not suppressed this phenomenon. After a long period of operation, it is easy to cause damage or leakage of the device itself, which is extremely serious. The reduced service life, can not meet the use
