S2：According to the pressure value of cooling section 8 detected, the air quantity that cooling section 8 is extracted out of D grades toilets 15 is adjusted,
So that the pressure stability of cooling section 8 is within a preset range.
It is cold by adjusting introducing when the cooling section 8 of tunnel dryer is fluctuated by the influenced by wind pressure in B grades of toilets 14
But the air quantity of section 8, so as to which the air quantity poured into out of B grades toilets 14 be made to be maintained at introducing air quantity summation from D grades of toilets 15
In certain range, so as to which the pressure of cooling section 8 be made to keep in a certain range, so as to avoid each technique inside tunnel dryer
Region laminar flow disturbance moves and sinuous flow, while while 8 pressure of cooling section is controlled, can make the pressure of D grades of toilets 15 with B
Grade toilet 14 fluctuation and respective change, so as to which the relative pressure stabilization between B grades of toilets 14 and D grades of toilets 15 be made to exist
In certain section, so as to ensure the stability of production environment；And the control method principle of the present invention is simple, easy to operate.
In the present embodiment, the specific control process of step S2 is：When 8 pressure value of cooling section detected is more than preset standard
During threshold value, the air quantity that the laminar flow air inducing component of cooling section 8 is extracted from D grades of toilets 15 is reduced；When 8 pressure of cooling section detected
When value is less than preset standard threshold value, increase the air quantity that the laminar flow air inducing component of cooling section 8 is extracted from D grades of toilets 15, so that cold
But the pressure stability of section 8 is within a preset range；In addition the exhaust air rate of cooling section 8 and total exhaust air rate of D grades of toilets 15 are protected
Hold constant, control principle is simple, easily operated.
In the present embodiment, in step sl, while the pressure in B grades of toilets 14 is detected, when the cooling section 8 detected
When pressure value is more than the pressure value of B grades of toilets 14, then the pressure anomaly in B grades of toilets 14 is judged.
The invention also discloses a kind of for adjusting the control system of tunnel sterilization dryer laminar flow zone wind pressure, including control
Component 16 processed and the pressure detecting assembly for detecting 8 pressure of cooling section of B grades of toilets 14 and 15 junction of D grades of toilets
10, pressure detecting assembly 10 is connected with control assembly 16；Pressure detecting assembly 10 detects the pressure value of cooling section 8 and is sent to control
Component 16 processed, control assembly 16 control the laminar flow air inducing component of cooling section 8 so that cooling section 8 according to the pressure value of cooling section 8
Pressure is in preset range.
In the present embodiment, control assembly 16 is programmable controller（PLC）；Pressure detecting assembly 10 is wind pressure sensor；
The laminar flow air inducing component of cooling section 8 is laminar flow wind turbine.
In the present embodiment, as shown in Figure 1, tunnel sterilization dryer includes preheating section 1 and cooling section 8, wherein in preheating section 1
Preheating high efficiency particulate air filter 2, preliminary heating zone flow fan 3 and dehumidifier exhaust duct 4 are provided with, dehumidifier is set to arrange on dehumidifier exhaust duct 4
Wind wind turbine 11 is provided with cooling layer flow fan 5, cooling high-efficiency filter 6 and cooling, air discharging pipeline 7, cooling, air discharging in cooling section 8
Cooling, air discharging machine 9 on pipeline 7 is set, air-valve 13, and two pipes are wherein both provided in dehumidifier exhaust pipeline and cooling, air discharging pipeline 7
Road is provided with total air inducing wind turbine 12 after converging.
Its specific control process is as follows：By monitoring the pressure of cooling section 8, when B grades of toilet 14 relative pressures increases, then
Its relatively cool section 8 pressure difference becomes larger, and the air that B grades of toilets 14 pour into cooling section 8 increases, and the pressure of cooling section 8 is then corresponding
The pressure value of cooling section 8 is fed back to the PLC of tunnel sterilizing dryer by increase, and PLC reduces the rotating speed of cooling layer flow fan 5,
The relative pressure for making cooling section 8 is constant, at this time due to sky that tunnel sterilizing dryer cooling section 8 is extracted from D grades of toilets 15
Gas is reduced, and D grades of toilet's 15 pressure increases, with respect to B grades 14 pressure differences of toilet restore in normal range (NR)；When B grades of toilets 14
Relative pressure reduces, and relatively cool section 8 of pressure difference reduces, and the air that B grades of toilets 14 pour into cooling section 8 is reduced, cooling section 8
Pressure then accordingly reduce, the pressure value of cooling section 8 is fed back to tunnel sterilizing dryer PLC, PLC then improves cooling laminar flow
The rotating speed of wind turbine 5, the relative pressure for making cooling section 8 is constant, and tunnel sterilizing dryer cooling section 8 is from D grades of toilets 15 at this time
The air of extraction increases, and D grades of 15 pressure of toilet reduce, and with respect to B grades 14 pressure differences of toilet restore normal；In addition in control process
Middle dehumidifier exhaust blower wind turbine and 9 rotating speed of cooling, air discharging machine do not change, and draft capacity is kept constant.
It is exemplified below：Pressure differential such as the opposite D grade toilets 15 of preheating section 1 is 6Pa, with respect to D grades toilets 15 of high temperature section
Pressure differential for 8Pa, the pressure differential of the opposite D grade toilets 15 of cooling section 8 is then 7Pa, and B grades of toilets 14 are clean relative to D grades
The pressure difference of room 15 is 15Pa, then B grades of toilets 14 are 8Pa relative to 8 pressure difference of cooling section, as B grades of 14 relative pressures of toilet increase
Greatly, it is 20Pa to make B grades of toilets 14 and D grades of 15 relative pressures of toilet, then B grades of 14 relatively cool sections of toilet, 8 pressure differences are
（20-7）Pa, i.e. 13Pa, B grades of toilets 14 pour into 8 air of cooling section and increase, if do not handled the air increased, then 8 phase of cooling section
D grades of 15 pressure differences of toilet will be become greater than with 7Pa, former tunnel sterilizing dryer internal differential pressure is by disequilibrium.It now will cooling
The 8 laminar flow wind turbine amounts of collecting folk songs of section reduce, and holding 8 pressure of cooling section is constant, then not only tunnel sterilizing and drying machine internal pressure can protect
Hold constant, D grades of 15 pressure of toilet can also increase, and gradually revert to 2 toilet's relative pressures.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention should be regarded as the protection of the present invention
