反應釜內加熱管與釜體連接型式的常規結構為焊接結構,在使用過程中,常在焊接處發生破壞現象,經過改進,取消了焊接結構,杜絕焊接應力的產生,同時在使用中,加熱管的震動也減弱了,有效地防止了疲勞破壞的發生。
[Abstract] the conventional structure of the reaction kettle heating pipe and the kettle body connection type for welding structure, in use process, the damage often occurred in welding parts, modified, canceled the welding structure, to eliminate welding stress, while in use, the heating pipe vibration is weakened, effectively prevent the occurrence of fatigue failure.temperature
Φ=hA△t=170×π×0.95×1.25×(430-160)=17123.6W
Phi =hA △ t=170 * pi * 0.95 * 1.25 * (430-160) =17123.6W
第二步:由于只計算穩定狀態的結果,所以管外熱量全部被流動水流所帶走的熱量應該是?反應釜加熱管
The second step: the calculation of the steady state results, so the pipe heat is the heat taken away by water flow should be
Φ=ρμκυ△t=ρμAC(t out-t in)
Phi = P Mu kappa upsilon Delta t= ρ AC (t Out-t in
∴t out=Φ/pUAC+t tn= 17123.6/ 980×0.1×π/4(d-28)2×4184
* t out= /pUAC+t tn= 17123.6/ Φ 980 × 0.1 × π /4 (D-28) 2 × 4184
