Fig. 2 is the schematic diagram of the smoke evacuation system of central range hood；Fig. 3 is based on aerodynamic principle, the row of foundation
The physical model figure of cigarette system；Fig. 4 is the branch pipe dynamic model figure intercepted from smoke evacuation system.
As shown in figs 2-4, central fume-exhausting includes the host 4 that roof is arranged in and the terminal that each floor is arranged in
Machine 2 (i.e. slave), terminating machine 2 are connected by branch pipe 3 (lateral), check-valves and common flue 1, and terminating machine 2 passes through power
Distributing valve is connect with branch pipe 3, for oil smoke to be discharged according to the air quantity of host assignment.In branch pipe dynamic model figure, f is interflow
Entrance, m are interflow outlet, and S is manifold inlet, according to aerodynamics, it is known that following two formula (1) and (2):
Pm=Pf+aQf 2, QS=0, (1)
Pm=Pf+ b, PS=Pm- c, QS>0 (2)
Wherein, QSFor air quantity at S；QfFor the air quantity at f；PmFor the wind pressure at m；PfFor the wind pressure at f；PSFor the wind at S
Pressure, a are along journey coefficient, and b is interflow coefficient, and c is branch tube cofficients；In the situation identical with material of the aperture of common flue, a is
Constant, and b and c are with QfVariation.
In central range hood, slave and slave are vertically connected with, at the f of n-th layer at the as m of (N-1) layer,
Therefore, there are following formula (3) and (4):
Pf(N)=Pm(N-1) (3)
Qf(N)=Qf(N-1)+QS(N-1), QS>0 (4)
The purpose of the power distribution method of the embodiment of the present invention is to keep the air quantity of each booting slave constant, i.e., each booting
The Q of slaveSIt is identical.Known QSValue and in the case which floor booting slave be located at, and known a, b (K)
With c (K), b (K) and c (K) indicate that b and c is with QfVariation, i.e., the value of different floors is different, according to formula (1), (2),
(3) and (4) obtain the pressure P at each lateral by recursionS。
Further, according to PSTarget opening angle θ needed for the power distributing valve valve of slave can be calculated, with specific reference to
Following formula (5) is calculated:
θ=x (PS+y)+z
Wherein, θ is target opening angle；X, y, z is respectively coefficient related with the valve body structure of power distributing valve；PSFor
Wind pressure at the lateral of each slave.
It should be noted that y, z are influenced by the valve body structure of power distributing valve due to coefficient x, coefficient a and b (K)
It is influenced by flue size, c (K) is influenced by the smoke machine structure of each floor.Flue corresponding coefficient a, b can be tested in advance
(K), the valve body structure of power distributing valve and smoke machine structure are selected as needed, and can test corresponding coefficient x, y, z,
c(K)。
By taking 6 floors as an example, it is desirable that the balanced air quantity for the slave that is switched on is q, it is assumed that 1,3,5 floor of operating condition is opened, and 2,4,6
Floor closes, it is known that x, y, z, a, b1, b2, b3, b4, b5, b6, c1, c2, c3, c4, c5, c6, passed through according to formula (1), (2), (3) and (4)
Recursion obtains the pressure P at the lateral of each floorS。
The wind pressure being calculated at the f of each floor first is as follows:
Pf(1)=0, Pf(2)=b1, Pf(3)=b1+aq2,
Pf(4)=b1+b2+aq2, Pf(5)=b1+b2+5aq2, Pf(6)=b1+b2+b3+5aq2,
The pressure P at the lateral of each floor is calculated according to the wind pressure at the f of each floorS:
Ps (1)=b1-c1, Ps (2)=0, Ps (3)=b1+b2+aq2-c3,
Ps (4)=0, Ps (5)=b1+b2+b3+5aq2-c5, Ps (6)=0.
According to the above PSThe target opening angle θ of the power distributing valve of each booting slave can be calculated in value.
Further, according to the total blast volume 3q and wind pressure Pm (6) of 6 layers of attic of interflow outlet, available host institute
The target power value needed, the i.e. target frequency of blower.Specifically, according to preset wind pressure component curve, blowing machine can be calculated
Target frequency.
Therefore, when each operating condition changes, the θ of each floor valve of adjustment of each booting slave is calculated according to the above method
The power value of value and host, makes each slave dynamic balnce.
In another embodiment, in step S101 it is each booting slave power distributing valve target opening angle also
It can calculate in the following manner:
Maximum angle is set by the target opening angle of the power distributing valve of the booting slave farthest with host distance, is led to
It is often 90 degree；
The target opening angle for setting all booting slaves meets linear decrease from bottom to up, and has the first decrement value
With the second decrement value；
The target of the power distributing valve of each booting slave is calculated according to maximum angle, the first decrement value and the second decrement value
Opening angle.
In practical applications, when center is used for range hood when 6 floor, including x, y, z, a, b1, b2, b3, b4, b5, b6,
c1, c2, c3, c4, c5, c6, 16 parameters in total, and total floor is more, and number of parameters is more.Parameter is more, central fume-exhausting
The difficulty and reliability of machine operation are lower, are unfavorable for the control of system.Therefore, following simplified calculations can be used.
It according to actual test and is calculated, works as QSWhen=0, PmWith PfVery close to that is, relative to b value, a value can be ignored
Disregard, and relative to b value, c value also be can be ignored.In addition b1It is worth bigger, and b2~b6Value is relative to b1For value compared with
It is small, it is believed that it is consistent, it is set as b.It is also supposed that operating condition is that 1,3,5 floors are opened, 2,4,6 floors are closed.
The wind pressure being calculated at the f of each floor is as follows:
Pf(1)=0, Pf(2)=b1, Pf(3)=b1,
Pf(4)=b1+ b, Pf(5)=b1+ b, Pf(6)=b1+ 2b,
The pressure P at the lateral of each floor is calculated according to the wind pressure at each floor fS:
Ps (1)=b1, Ps (2)=0, Ps (3)=b1+ b,
Ps (4)=0, Ps (5)=b1+ 2b, Ps (6)=0,
Therefore, it can be deduced that:
Ps (1)=b1, Ps (2)=0, Ps (3)=Ps (1)+b,
Ps (4)=0, Ps (5)=Ps (3)+b, Ps (6)=0.
Because 1 slave is farthest from host, in order to keep power optimal, the opening angle of slave 1 is set as maximum, usually
90 °, and by above-mentioned calculated result it is found that the Ps of booting slave from bottom to up is linear decrease, it is believed that its θ is also line
What property was successively decreased, this decrement value is set as angle [alpha].
Due to the P of shutdown slave from bottom to upfIt is also linear decrease, in order to correct the influence for ignoring a value, can recognizes
θ for booting slave from bottom to up has another decrement value, is set as angle beta (β < < α).
By taking above-mentioned operating condition as an example, the target opening angle of the power distributing valve of each slave is obtained:
θ1=90, θ2=0, θ3=90- alpha-beta, θ4=0, θ5=90-2 α -2 β, θ6=0.
Wherein, the value of α, β by x, y, z, a, b (K), the value of c (K) is simplified come so α, β by test comparison
Value is determined by flue size, the valve body structure of power distributing valve, range hood structure, can test to obtain the value of α, β in advance.
Step S102 adjusts the opening angle of the power distributing valve of each booting slave by target opening angle；In addition,
The opening angle of the power distributing valve of shutdown slave is 0；
Step S103 drives the blower of host to work according to target power value, to distribute balanced wind for each booting slave
Amount.
In the present embodiment, influences power and distribute balanced factor, the mainly opening angle of the power distributing valve of slave
With the power value of host.In practical applications, power distributing valve and host are Mass productions, can in order to be applicable in various scenes
Go out the interface of power allocation of parameters with advance reservation, for example, power allocation of parameters can be the value of above-mentioned α, β, then according to need
Parameter interface is set, realizes dynamic balnce distribution.
