The heat exchanger feed regulator of a kind of pulse vacuum pressuresteam sterilization equipment as described in Fig. 1-3, comprise temperature sensor 11, shell-and-tube heat exchanger 1, filter 4, manual ball valve 3, magnetic valve 2, single chip control unit, alarm module, described shell-and-tube heat exchanger 1 is divided into main body and arm, the main body of shell-and-tube heat exchanger 1 is provided with water vapour import 6, steam outlet 8 and running water outlet 7, described water vapour import 6 is connected with the sterilization bin of pulse vacuum pressuresteam sterilization equipment, described steam outlet 8 is connected with the vavuum pump of pulse vacuum pressuresteam sterilization equipment, in the present embodiment, described vavuum pump adopts liquid-ring vacuum pump.
The arm of shell-and-tube heat exchanger 1 is provided with running water inlet 5, described temperature sensor 11 has two, be separately positioned on the tube chamber oral area of the shell-and-tube heat exchanger 1 at water vapour import 6 and steam outlet 8 place, described filter 4 is arranged on the arm between running water inlet 5 and shell-and-tube heat exchanger 1 main body, filter 4 can filter the running water of suction shell-and-tube heat exchanger 1 and purify, described magnetic valve 2 is arranged on the arm between filter 4 and shell-and-tube heat exchanger 1 main body, described manual ball valve 3 is arranged on the arm between magnetic valve 2 and shell-and-tube heat exchanger 1 main body, the described signal output part of temperature sensor 11 is connected with the signal input part of single chip control unit, first signal output part of single chip control unit is connected with magnetic valve 2, secondary signal output is connected with alarm module.
The main body of shell-and-tube heat exchanger 1 is vertically arranged, described water vapour import 6 is arranged on the bottom of shell-and-tube heat exchanger 1 main body, steam outlet 8 is arranged on the top of shell-and-tube heat exchanger 1 main body, described running water exports 7 sides and opens on the top of shell-and-tube heat exchanger 1 main body, the main body of shell-and-tube heat exchanger 1 is divided into outer tube and interior pipe, described outer tube is water vapour passage 9, the lumen diameter of outer tube is greater than 30 centimetres usually, present embodiment preferably its lumen diameter is 30 centimetres, the water vapour that need cool and discharge is discharged by outer tube, described interior pipe is for being arranged on the intraluminal running water path 10 of outer tube, described running water path 10 adopts metal material to make, the lumen diameter of described interior pipe is 2 to 3 centimetres, one end of described running water path 10 is communicated with the arm of shell-and-tube heat exchanger 1, the other end exports 7 with the running water being arranged on shell-and-tube heat exchanger 1 body top and is communicated with.
The interior pipe quantity be arranged in outer tube is generally 15 to 25, present embodiment preferably arranges 19 running water path 10s in water vapour passage 9, for the running water of cooling water steam through running water path 10 to water vapour passage 9 in the vapours of process cool, its concrete cooling principle allows vapours and many root timbers matter be that the tube wall of the running water path 10 of metal contacts, taken away the heat of steam by the cold water of constantly flowing in running water path 10, thus realize lowering the temperature and condensation to steam.
When high vacuum autoclave with pulsing system needs the vapours in pump drainage sterilization bin, primer fluid ring vacuum pumps, water vapour in high vacuum autoclave with pulsing system in room is just drawn into liquid-ring vacuum pump suction inlet by the water vapour passage 9 of shell-and-tube heat exchanger 1, when water vapour enters the water vapour passage 9 of shell-and-tube heat exchanger 1, the temperature sensor 11 being arranged on water vapour import 6 place of shell-and-tube heat exchanger 1 can detect the temperature of water vapour, and the temperature signal detected sends to single chip control unit, single chip control unit sends corresponding control instruction to the magnetic valve 2 be positioned on shell-and-tube heat exchanger 1 support according to its temperature signal received, if during the setting value of the temperature value that temperature sensor 11 detects higher than single chip control unit, single chip control unit Controlling solenoid valve 2 is opened, extraneous running water enters many running water path 10s in shell-and-tube heat exchanger 1 by magnetic valve 2, thus condensation is carried out to the high-temperature steam in shell-and-tube heat exchanger 1, discharge from the outlet of liquid-ring vacuum pump through cooled water vapour.
The concrete control program that single chip control unit Controlling solenoid valve 2 is opened is: when water vapour enters the water vapour import 6 of shell-and-tube heat exchanger 1, the temperature sensor 11 be arranged on herein can detect the temperature of the water vapour import 6 of shell-and-tube heat exchanger 1, and signal is sent to single chip control unit, single chip control unit is changed the temperature signal received and is compared with the temperature range of setting, and sends a signal to magnetic valve 2 to open corresponding gear to regulate the inflow of running water.The setup control value of temperature sensor 11 arranged water vapour import 6 place is that less than 80 DEG C magnetic valves 2 cut out; 80 DEG C ~ 90 DEG C magnetic valves 2 open one grade; Second gear opened by 90 DEG C ~ 100 DEG C magnetic valves 2; Third gear opened by 100 DEG C ~ 120 DEG C magnetic valves 2; Fourth gear (standard-sized sheet) opened by 120 DEG C ~ 150 DEG C magnetic valves 2.
After water vapour carries out condensation by shell-and-tube heat exchanger 1, when arriving steam outlet 8, the temperature sensor 11 being arranged on steam outlet 8 place can the temperature of detector tube shell heat exchanger 1 steam outlet 8, the setup control value of temperature sensor 11 arranged steam outlet 8 place is 70 DEG C, after water vapour have passed through the cooling of shell-and-tube heat exchanger 1, its temperature can reduce, therefore to the setup control value of the temperature sensor 11 that steam outlet 8 place is arranged lower than the setup control value of the temperature sensor 11 arranged water vapour import 6 place, the temperature value signal detected is sent to single chip control unit by the temperature sensor 11 that steam outlet 8 place is arranged, single chip control unit is changed the temperature signal received and is compared with the temperature value 70 DEG C of setting, if be less than the temperature value 70 DEG C of setting, then single chip control unit sends signal at stop magnetic valve 2, to stop water inlet, otherwise continue water inlet, and then achieve the real-time control of shell-and-tube heat exchanger 1 water inlet, decrease the waste of water resource.
When the control instruction that the detected value of the temperature sensor 11 arranged according to steam outlet 8 place sends, when the control instruction sent with the detected value of the temperature sensor 11 arranged according to water vapour import 6 place clashes, the control instruction that the preferential detected value performing the temperature sensor 11 arranged according to steam outlet 8 place sends.
When abnormal conditions appear in magnetic valve 2 or temperature sensor 11, single chip control unit sends control signal and reports to the police to alarm module, to point out fault.Now can open the manual ball valve 3 in magnetic valve 2 bypass, continue to provide cold water to the water supply pipe 10 in shell-and-tube heat exchanger 1, to continue condensation to by the water vapour in the water vapour passage 9 of shell-and-tube heat exchanger 1, thus reduce the temperature entering liquid-ring vacuum pump water vapour, reduce the noise of liquid-ring vacuum pump, ensure that liquid-ring vacuum pump continues normal operation.
The above, it is only preferred embodiment of the present invention, not any restriction is made to technical scope of the present invention, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
