The observation visual angle that the utility model uses user is described, but the above-mentioned noun of locality cannot understand or be not construed as to this reality
With the restriction of novel protected range.
The course of work of hanging basket regenerative air preheater described in the utility model is described below.
The hanging basket regenerative air preheater is installed on heating-furnace when being applied to petroleum chemical heating furnace residual neat recovering system
Side ground, tetra- interfaces of A, B, C, D of the hanging basket regenerative air preheater by flange, bolt etc. respectively with corresponding flue,
Air duct connection, in which: hot fume enters from the A mouth of the second airflow channel 3 (flue gas heat exchange room), and hot fume is in the second airflow channel
It exchanges heat in 3 (air heat-exchange rooms) with the hanging basket for stopping or moving to the room, the heat storage heating by hanging basket and wherein loaded,
After flue gas passes through hanging basket heat exchange cooling, flue-gas temperature is reduced to 110 DEG C or so even lower (minimum to be down to 80 DEG C), cold flue gas
It is exported from B mouthfuls, is sent into smoke stack emission through smoke induced draught fan；Cold air is sent by air blower from the C mouth of the first airflow channel 4, with
The hanging basket heat exchange of the room is moved to after smoke pre-heating, cold air passes through hanging basket and heat storage therein and constantly heat absorption heating,
Hot-air is sent out from the D mouth of the first airflow channel 4, and be sent to burner for heating furnace through residual neat recovering system hot-flow flue makes for burning
With.
Constantly movement is logical in the second airflow channel 3 (flue gas heat exchange room) and the first air-flow for first hanging basket 1, the second hanging basket 13
Road 4 toggles between (air heat-exchange room), constantly by flue gas waste heat for heat exchange to combustion air, to realize air preheat
Function.The motion-promotion force of hanging basket is provided by driving device, and switching cycle can be adjusted according to required smog discharge temperature
Whole, the frequency of hanging basket switching is related with required heat exchange power.Under same operating condition, it is desirable that when smog discharge temperature is lower, hanging basket fortune
Dynamic switching frequency is very fast, and preheater recycling heat increases, and the temperature that air is preheated is relatively high, then furnace fuel amount is corresponding
It reduces, thermal efficiency of heating furnace improves；Conversely, under same operating condition, it is desirable that exhaust gas temperature it is higher when, hanging basket moves switching frequency drop
Low, preheater recycles heat and reduces, and air is preheated temperature decline, then furnace fuel amount accordingly increases, thermal efficiency of heating furnace
Decline.
1 hanging basket heat exchange structure group being made of 2 hanging basket groups, a preheater at least contain 1 hanging basket heat exchange structure group.
When exhaust gas volumn is larger, heat exchange power is larger, and required heat storage quantity is big, to avoid suspension arrangement load excessive, hanging basket volume
It is excessive, make precision and the increased risk of service requirement, it is necessary to which 2 or more hanging basket heat exchange structure groups, multiple heat exchange are set
Unit is installed side by side, and the commutation cycle of hanging basket group therein is the same, is uniformly controlled by control cabinet, and the period can be according to exhaust gas temperature
Adjustment.But multiple hanging basket groups commutate in turn, and in a cycle, commutating period, interval should be uniform between hanging basket group, to keep cigarette
Duct pressure and temperature it is constant, avoid the occurrence of larger fluctuation, influence furnace operation safety.
The above, only specific embodiment of the utility model cannot limit the range that utility model is implemented, institute with it
With the displacement of its equivalent assemblies, or according to equivalent variations made by the utility model patent protection scope and modification, should all still fall within
The scope that this patent is covered.In addition, between technical characteristic and technical characteristic in the utility model, technical characteristic and technical application
Between novel, technical application it is novel it is novel with technical application between use can be freely combined.
