Background technology
Heat exchanger is used in the power plant and incineration firing equipment that utilizes fossil fuel operation in addition, in order to not have in the situation about directly contacting thermal energy transfer with first fluid, for example flue gas (Rauchgas) between two fluids on second fluid, for example air.In this case, such device is also referred to as air preheater.Air preheater for example is used to the preheating of combustion air in industry and the power plant burning equipment and for example is used to the preheating of gas washing (Gasw sche) gas afterwards and heats in exhaust gas cleaning.In principle, air preheater can be used as heat regenerator (Regenerator) and be used as recuperator (Rekuperator).Usually use heat regenerator for high thermal power to be passed.
In rotary type heat exchanger (it belongs to the cohort of heat regenerator), the process gas of heat and gas to be heated, below be also referred to as input air (Zuluft) and flow through same structure, so-called " storage substance " on the time with staggering, it has a large amount of passages.In the air preheater of so-called " Ljungstr m " structure type, storage substance is turn-taked lentamente, and wherein passage alternately contacts with the flue gas of heat or cold input air and the heat that will absorb from flue gas is thus passed to input air so that be included in.
According in the AC system air preheater of " Rothem ü hle " structure type, storage substance regularly (as stator) is configured in the housing with at least two rotary covers, and it synchronously rotates in the stator above and below.Housing is corresponding at least one entrance and exit that comprises for process gas and input air in addition.Process gas or input gas are guided through the rotary cover that rotates in static passage, and corresponding another gas (input air or process gas) is guided through these static passages, so that alternately flow through all passages of stator with process gas or input air and heat transmission can occur thus.Alternatively, not only process gas but also gas to be heated also can correspondingly be guided through the rotary cover of rotation.
Especially when the heat energy that should be used to from flue gas or burning gases (it can comprise thin particles/dust, metallic vapour and/or other corrosive material usually), must with periodic interval realize the heat transfer of heat exchanger contact-making surface, that is to say the cleaning of inner surface.Otherwise such electrodeposition substance is result on the contact-making surface that conducts heat cause, the diameter of the passage of flow path obviously reduce or itself in addition stop up, this efficient that can obviously reduce corresponding equipment maybe can cause it to stop.
