Water supply device includes for water box 7 and water storage case 8, and water storage case 8 is connected with steam generator 2, and water can in water storage case 8
To be independently flowed into steam generator 2.
For being connected with intake tunnel 91 and backwater channel 92 between water box 7 and water storage case 8, be connected on intake tunnel 91 into
Water pump 911 and inlet valve 912 are provided with back water pump 921 and back-water valve (BWV) 922 on backwater channel 92.
It steams in chamber 1 and is provided with pressure sensor 101 and temperature sensor 102, pressure sensor 101 and temperature sensor
102 position can be specifically arranged according to the specific structure for steaming chamber 1.Control circuit board 10 respectively with steam pump, steam generator
2, intake pump 911, inlet valve 912, back water pump 921, back-water valve (BWV) 922, pressure sensor 101, temperature sensor 102 are electrically connected,
And then control circuit board 10 may be implemented to steam pump, steam generator 2, intake pump 911, inlet valve 912, back water pump 921, return
The control of water valve 922, pressure sensor 101, temperature sensor 102 guarantees to carry out cooperating between them.The control circuit
Plate 10 can be using the master control circuit board 10 in electric steam box.
As shown in figure 3, the steam circulation control method realized using steam circulation above-mentioned, comprising the following steps:
S1, initialization, setting steam circulation start pressure threshold, and setting 2 filling of steam generator starts pressure threshold, if
It sets under steam circulation starting pressure threshold, steams 1 pressure of steaming chamber in chamber 1 after the corresponding discharge of steam of different temperatures range and retain
Value；2 filling start-up temperature threshold value of steam generator is set；The temperature threshold that stops working that steam generator stops working is set；
Start work；
S2, control circuit board 10 control inlet valve 912 and open, and control circuit board 10 controls intake pump 911 simultaneously and starts work
Make, and then will be pumped into water storage case 8 for the water in water box 7, the water in water storage case 8 is flowed into steam generator 2；
Control circuit board 10 controls steam generator 2 and starts work generation steam, and steam, which enters, to be steamed in chamber 1, control electricity
Road plate 10 controls steam drive apparatus 5 and keeps halted state；
S3, control circuit board 10 obtain the pressure signal for steaming the acquisition of 1 pressure sensor 101 of chamber in real time, and judge to steam chamber 1
Interior pressure whether be more than setting steam circulation starting pressure threshold；If it is, carrying out S4；
Meanwhile control circuit board 10 obtains the temperature steamed and steamed in chamber 1 when pressure in chamber 1 reaches steam circulation starting pressure threshold
Degree evidence, and the 1 pressure retention of steaming chamber when the secondary discharge of steam after is determined according to the temperature data；
After S4, steam generator 2 carry out work until reaching the temperature threshold that stops working that steam generator stops working,
Control circuit board 10 controls steam generator 2 and stops working；
Control circuit board 10 controls inlet valve 912 and closes, while controlling intake pump 911 and stopping working；
S5, control circuit board 10 control steam drive apparatus 5 and work, and then steam extra in steaming chamber 1 is driven to enter
It is steamed in chamber 1 in steam generator 2 and through being re-entered into vapour channel 3；
When the pressure data that control circuit board 10 obtains steaming 1 pressure sensor 101 of chamber acquisition reaches when time discharge of steam
After 1 pressure retention of steaming chamber afterwards, then steam off driving device 5 is controlled；
S6, control circuit board 10 obtain the pressure signal for steaming the acquisition of 1 pressure sensor 101 of chamber in real time, and judge to steam chamber 1
Whether interior pressure is less than 2 filling of the steam generator starting pressure threshold of setting；If it is not, then returning to S5；
If so, control circuit board 10, which obtains, steams steaming when pressure in chamber 1 reaches 2 filling of steam generator starting pressure threshold
Temperature data in chamber 1, if the temperature data steamed in chamber 1 at this time is less than or equal to 2 filling start-up temperature threshold value of steam generator,
S2 is then directly carried out, if the temperature data steamed in chamber 1 at this time is greater than 2 filling start-up temperature threshold value of steam generator, is waited
Control circuit board 10 obtains after the temperature steamed in chamber 1 drops to 2 filling start-up temperature threshold value of steam generator and carries out S2 again；Pass through
The deterministic process of temperature data, most the maximum amount of effective use steam heat in the case where capable of being worked normally in chamber 1 is steamed in guarantee,
It is more advantageous to the raising for realizing capacity usage ratio；
In addition it can realize the raising of capacity usage ratio by another temprature control method: i.e. in S1, setting is steamed
2 filling of vapour generator starts under pressure threshold, steams the different temperatures range corresponding 2 delay start time of steam generator in chamber 1
Value；
In S6, control circuit board 10, which obtains, steams steaming when pressure in chamber 1 reaches 2 filling of steam generator starting pressure threshold
Temperature data in chamber 1, and then determine when time 2 delay start time of steam generator, so that control circuit board 10 is according to when secondary
The 2 delay start time of steam generator controls 2 delay start of steam generator；
S7, control circuit board 10 detect power cut-off signal, after control circuit board 10 receives power cut-off signal,
Control circuit board 10 controls inlet valve 912 and opens, while controlling intake pump 911 and starting work；So with for low in water box 7
Warm water is also accordingly flowed into steam generator 2 after being flowed into water storage case 8, is mixed with the high-temperature water in steam generator 2, such as
This is gradually reduced the water temperature in steam generator 2 and water storage case 8；After a period of work to intake pump 911, steam generation
The water temperature of water again can not impact the performance of back water pump 921 and back-water valve (BWV) 922 in device 2 and water storage case 8, control circuit board 10
The closing of inlet valve 912 is then controlled, while controlling intake pump 911 and stopping working；Then control circuit board 10 controls back-water valve (BWV) 922 and beats
It opens, while controlling back water pump 921 and starting work, by the water return water in steam generator 2, water storage case 8 to for guaranteeing in water box 7
Dry environment in steam generator 2 and water storage case 8.
By the steam circulation control method to the circular treatment of steam, realization that can be effective and substantive is to steam energy
Recycling, substantially increase the energy utilization rate of steam circulation, reduce energy consumption.2 need of steam generator simultaneously
Discontinuous operation is wanted, without continuing working, reduces the energy consumption of steam generator 2, while being also beneficial to improve steam generator 2
Service life.
