AnalysisShelter is a new technology that became popular in countries around the world in the mid-to-late 1980s. It integrates the configuration, complete equipment, and installation of industrial online instruments, and has been widely applied in oil refining and chemical engineering.The standardized and systematic design of the on-site analysis unit makes instrument installation, commissioning, and maintenance convenient, and also provides a good operating and control environment for the instruments, leading to increasing application in process equipment.。

The explosion-proof house belongs to a general term. The professional term in the industry is positive-pressure explosion-proof analysis house, while many customers affectionately call it the explosion-proof station, CEMS flue gas online monitoring station, VOCs online monitoring analysis house, CEMS analysis house, etc. no matter what it is called, its function is the same, and explosion-proofing is the key.。

2. Positive-pressure ventilation type explosion-proof analysis house: non-explosion-proof detection instruments and various instrument cabinets can be installed inside the room. Only after the explosion-proof positive-pressure equipment operates and generates positive pressure inside the room can the non-explosion-proof parts inside the room be energized and operated.。

nowadays, explosion-proof analysis houses are widely used in environmental protection enterprises for online monitoring, inspection, and analysis.。

2. In the positive-pressure explosion-proof house, it is strictly prohibited to store or temporarily place any combustible, flammable, or easily ignitable items, and it is strictly prohibited to store or temporarily place corrosive items.。

3. During protection and maintenance, before entering the analysis house, personnel must turn on the explosion-proof axial flow exhaust fan outdoors through the explosion-proof switch.。

4. When people work inside the house, they must not close the door completely.。If the door is closed and a dangerous or combustion abnormal situation occurs, push the door handle outward, and the door can be opened to protect life safety.。

5. For the various power boxes, junction boxes, explosion-proof switches, backup power supplies, and their connecting parts inside the positive-pressure explosion-proof house, it is strictly prohibited to disassemble, loosen, or detach them while energized.。This can only be carried out after a power outage and after detection with a portable flammable gas alarm system.。

6. In daily maintenance of the positive-pressure explosion-proof house: Check the working status of external electricity and gas, and strictly prevent abnormalities in electricity and gas.。Check whether the instrument air supply is normal.。Check whether the sample gas has moisture or liquid carryover during the pretreatment process, and if abnormal, shut down for fault detection.。Check the working status of the instruments and whether there are any abnormalities in the DCS display (including historical curves).。Check whether the connected pipelines are abnormal.。Check whether the various configurations, equipment, explosion-proof device connections, pipeline connections, operating status, and flow and pressure indicators inside the analysis house are abnormal.。

7. Strictly comply with safety and fire protection regulations.。

8. Check once a month whether the explosion-proof centrifugal fan and combustible gas alarm inside the analysis house are operating normally.。

9. For indoor and outdoor lighting fixtures and emergency lighting fixtures, if they are found not to be lit, after a power outage and confirmation that the environment has no flammable and toxic gases, replace the bulbs or fluorescent tubes.。

10. For the explosion-proof instruments and explosion-proof components set up in the system, never handle them while energized.。Strictly comply with safety and fire protection standards.。

11. After replacing pretreatment components in the system or suspecting a leak at a certain point, a comprehensive leak inspection of the system must be carried out under the monitoring of someone.。ProhibitPreventsystemSoftComponentsDrainDew。Strictly prevent poisoning by harmful gases.。
