Generator waste heat utilization adjustment components

Abstract

The invention discloses a power generator waste-heat utilization regulating assembly which comprises a power generator, a plurality of groups of waste-heat utilization equipment, a flue gas flow-splitregulating device and a driving device, wherein the power generator is used for generating power and waste gas through combustion; the flue gas flow-split regulating device is arranged between the power generator and the waste-heat utilization equipment so as to change the flow direction and the flow rate of the waste gas, and comprises a shell and a floating ball valve arranged in the shell; a plurality of communicating holes are formed in the peripheral surface of the shell; one communicating hole is connected with the power generator through a gas exhaust pipe so as to receive the waste gas; pressure sensors are arranged on the gas exhaust pipe; other communicating holes are connected with the corresponding waste-heat utilization equipment through gas inlet pipes; and the driving device is used for driving the floating ball valve to move and enclose at most one communicating hole at the same time. According to the power generator waste-heat utilization regulating assembly disclosedby the invention, the number of utilization hours of a power generator set can be increased and the maximum utilization can be achieved through less regulating operation.

Description

Problems solved by technology

[0003] Generally, in order to ensure the stable and efficient power generation of the generator set, the generator set and the waste heat flue gas utilization equipment generally adopt a one-to-one principle. The pressure of the flue gas discharge needs to be kept stable, and when the flue gas enters the waste heat utilization unit, it is affected by the fluctuation of the cooling and heat demand at the end. Changes in the utilization of flue gas waste heat can easily lead to unstable flue gas discharge pressure, so that the generator set needs to meet the demand of end flue gas waste heat for partial load power generation or set up a bypass pipe to discharge excess flue gas to the atmosphere, resulting in waste heat waste

[0004] The existing waste heat utilization considers to ensure the back pressure of the flue gas emitted by the generator set, and gives up the possibility of diversifying the use of flue gas, or directly causes waste of flue gas, so there is room for improvement
