Eo scrubber which is also called eo, eto gas scrubber, is used for removing ethylene oxide from industrial exhaust streams by using eto מעקר
Eo gas scrubber process
Process Description of eo scrubber
The process description of eo gas scrubber
(1) Water volume and flow rate: the flow rate of the spay pump and the air volume of the centrifugal fan can be determined according to the exhaust volume of the vacuum pump;
(2) Acid medium for absorption reaction: 0.5-1.5% sulfuric acid solution (solid acid catalyst can be added);
(3) Temperature and pressure: Although the reaction is exothermic, the increase in temperature and pressure is limited. The reaction temperature is between normal temperature and 50°C, and the pressure is between slight negative pressure and normal pressure;
(4) waste liquid production: ethylene oxide reacts with water in the reactor tower to form a hybrid alcohol solution mainly composed of ethylene glycol.
לאחר התגובה, ריכוז האתילן גליקול בכור יעלה.
לאחר שצפיפות האתילן גליקול במגדל תגיע לערך הנקוב, נוזל הפסולת יועבר למיכל הנוזל העשיר באמצעות משאבת הנוזל העשיר, ולאחר מכן יתווסף הנוזל החדש.
(5) תוספת של נוזל טרי: לאחר ההעברה, יש להוסיף נוזל תגובה טרי לקומקום המגדל;
(6) נטרול תמיסה שנפלטה: יש לטפל ולמחזר את התמיסה שנפלטה על ידי כימיקלים מסוכנים מוסמך & יש לטפל במפעל לטיפול בפסולת, ובמניפסט העברת הפסולת המסוכנת (חמישה גיליונות).
(7) פרמטרים של ציוד: הספק הפעלה מקסימלי: 25kw;
EO Scrubber תכנון בטיחות חשמלי
On-site electrical devices such as motors, temperature sensors and pressure transmitters are of flame-proof type, and the explosion-proof grade is DIIBT4.
The isolation-type safety barrier, which is an intrinsically safe explosion-proof structure with the highest explosion-proof grade, is used for switch signal devices such as limit switch and liquid level switch.
Non-explosion proof cabinet body will be adopted if installed in the area with no explosion hazard and explosion-proof control cabinet will be adopted if installed on site.
Automatic control scrubber
Siemens PLC control system is adopted to ensure safe and reliable operation of the equipment.
The touch screen on-line monitoring system is adopted to realize good human-machine interface, so that operators can timely know the running status of the equipment in the daily production process.
In case of equipment failure, the operators can analyze and judge the cause of the failure in time and eliminate the failure with the help of the monitoring system.
A RS485 communication interface is reserved in the control system for the connection with the user’s DCS system. This interface supports Modbus protocol.
