Quritishning moddiy balansi tenglamasi

Kolorifen hisobi
Kolorifen tanlash uchun isitish yuzasini aniqlaymiz.
F= bunda Q=L_max*(C_x(t_i-t₀)

Bu yerda: C_x-0.241 kj/kgk

W₁=145ºC; W₀-2ºC

Q=L_max* C_x(W₁- W₀)=40.06*0.241(145-2)=1380.2

k=40NW/mk deb qabul qilamiz.

-2ºC→145ºC; W_kmv=152ºC; W_kh=5 ºC

= =30 ºC > 2 ºC


W_yr 43.2 ºC
F= 7.98m²

Ushbu hisob bo’yicha КФС – 11 kotariferni tanlaymiz.

КФС – 2 tip; F=9.9 m²; m=57.03 kp; ℓ= 360mm; h= 560mm; jonlomoqim

ϯ₁= 0.112m³; ϯ₂= 0.0046m²

Mexanik hisob.
Barabanning og’ish burchagi.
ά= +(0.007+W_x)
bu yerda : -uzunligi-14 m; n-aylanishlar-5ayl/min; d-diametri-2.8m²; W_x-tutun tezligi-6.8 m/s

ά= +0.007+ =11.8 ºC

N=0.078*ρ²*G*n

N=0.078*2.8²*14*1115*0.071*5=3.49kV

Batareyali siklon qurilma hisobi.
Berilgan boshlang’ich ma’lumotlar:

V_k=9500m³ =2.64

d_э=190mm

ρ₂=1k/m
Batareyali siklon hisoblanayotanda ko’pincha narmal nagruzkada ishlash uchun ⍙p =70 mm suv ustuni deb qabul qilsak, element diametrini esa d_э =190 mm deb qabul qilamiz.

Batareyali siklon elementlar sonini hisoblaymiz.

N=28.75*10² =28.75*10²* =11.7 Vm

Elementning sonini 12 deb qabul qilamiz. Gidravlik qarshilikni apparat uchun element diametrini 190mm bo’lib uning temperaturasi W=30 ºC dan katta bo’lsa, ρ=65 deb qabul qilamiz.

Silindrik qinidagi gazni tezligini hisoblaymiz.
Silindrik 1 element uchun sarfini hisoblaymiz.

V_g=0.785*D²*3600*W_k = 0.785*0.192²*3600*1.46=868.9 kl/s

Bizga kerakli elementlarni hisoblaymiz.

n= = =10.93

n=12 dona qabul qilganimiz to’g’ri ekan.
n₁=3 dona; n₂=6 dona deb qabul qilsak unda apparatni elpni hisoblashimiz mumkin.

B=d_эл*n₁+0.04(n₁+1)=0.190*3+0.04(3+1)=0.73mm

n= d_эл*2₁+0.04(n₂+1)=0.190*6+0.04(6+1)=2.42m

elementning ko’ndlangnkesim yuzasimi hisoblaymiz.

ϯ_эл= = =0,283mm²

Shu shtuserlar uchun flanetslibrikma tanlaymiz ГОСТ1255*67

D_k=300mm D₁=365mm

D_ф=435mm D₂=357mm

D_б=395mm d=23mm
