Oil-water separator cleaning how to do?

1. The oil-water separator can be directly installed in the oily sewage flow through the channel, the sewage outlet can be aligned with the oil-water separator with grille inlet, and other equipment can be connected with the pipeline. The bottom of the sewage line can be connected with the sludge dewatering device, such as not equipped with sludge dewatering device can be directly connected to the sewage pipe. 2, the installation of the oil-water separator must be adjusted to the level of its position, there should be no error. 3, the first time before use, the device should be filled with tap water, and then adjust the position of the adjustment plate on the equipment, until the outlet of the oil outlet only out of the oil does not come out of the water until the 4, adjust the plate adjusted, do not move, or will affect the water quality. Will affect the water quality of the water. 5, should pay attention to the water inlet filter on the debris poured out and cleaned up. (Catering industry should wash the oil and dirt on the filter screen with hot water, so as not to clog the filter screen and affect the water intake. If the pump is used to lift the water intake, please regularly clean up the pump intake bottom valve next to the dirt, so as not to clog the pump valve, affecting the flow of water intake.) 6, should pay attention to clean up the waste oil in the oil collection tank: first open the lower part of the tank drain valve, drain off part of the water, and then the waste oil collection. (In catering industry, if there are more animal oils than vegetable oils, the wastewater will form clumps and lumps, then you should open the drain valve first, drain off part of the water, and then open the tank cover and clean up the wastewater oil in the tank with a spoon.) Please keep the exterior of the unit tidy. Set the automatic oil and water discharge valve to open the compressed air input valve slowly (do not open the compressed air input valve in a hurry, so as to avoid the high-pressure rapids from impacting the inside of the equipment and causing damage to the parts). Carry out the adjustment of the required working air pressure, when the filter is in normal and stable working air pressure, pinch the drain valve of the lower part of the first filter by hand and rotate it to the left or right; when the automatic drain valve is rotated to the point that it just doesn't leak air, and then finally connect with a hose to lead the discharged condensate into a container; oil-water separator: the oil in the oily wastewater of the catering industry is mainly derived from the oil from the animal and vegetable oils being processed and mixed in the water, the floating oil, the dispersed oil, and the dispersed oil. Mixed in the water floating oil, dispersed oil, oil particles are relatively large.

How to completely remove the Trojan horse implanted in the cell phone?

One of the precautions to kill the virus:

1, first of all, when killing the virus, you have to close all the applications that are open, otherwise in the running state of the application, the cell phone antivirus software will automatically skip the non-detection, which may lead to the background of the silent running of the virus application, can not get scanned in a timely manner.

2, the kill time, keep the screen always on, some of the phone will kill when the automatic lock screen, resulting in the failure of the kill time.

3, after the completion of the anti-virus, anti-virus processing results, we must be based on the views of the anti-virus software to solve, do not think that the software used before all right, will be ignored at will, that is, the anti-virus software misreporting, which is very easy to lead to let go of the virus.

Two, remove the smartphone virus:

1, you can open the tencent cell phone butler page through the computer to scan the QR code to download, but also in the android market, APPSTORE, and other software management push center inside the download

2, open the tencent cell phone butler - click on the security protection - virus checking

3, according to the results of the scan, choose the malicious apps or viruses directly uninstalled or deleted.

Three, kill the virus after the processing, to ensure that the virus does not recur:

1, first of all, poisoning is generally a virus to use vulnerabilities to attack the phone, so the phone will be poisoned, it can also be understood that if the vulnerability is not repaired, the virus, even if temporarily cleaned up, the future will still appear, so the phone's system vulnerability must be timely to repair the Tencent cell phone butler in the system vulnerability function to go to timely repair.

2, for some of the removal, but after restarting the phone, the cell phone virus will appear again, called stubborn Trojan, for this kind of virus should use some special tools.

1)Open the Tencent cell phone manager, click on the upper right corner of the four dots logo, open the toolbox.

2)Then point to add tools, in which you can find a stubborn Trojan special kill, directly point to add, and then use this tool to kill the virus can be.

The above is the way to remove smartphone virus.

What is the heat exchanger cleaning method?

1.Connect the transfer pump and connecting conduit so that the cleaning agent is pumped in from the bottom of the heat exchanger and out from the top.

2. Repeat the cycle of cleaning to the recommended cleaning time. As the cycle progresses and the sediments dissolve, the gas generated during the reaction increases, and the excess air should always be discharged through the bleeder valve. As the air is discharged, the space inside the heat exchanger will increase, and appropriate water can be added, do not inject a large amount of water at the beginning, which may cause water overflow.

3, the cycle should regularly check the effectiveness of the cleaning agent, you can use PH test paper to determine. If the solution remains at a PH value of 2_3, then the cleaning agent is still effective. If the PH value of the cleaner reaches 5_6, you need to add another appropriate amount of Fosetek cleaner.

4. After reaching the cleaning time, recover the cleaning solution. And use water to rinse the exchanger repeatedly until rinsed clean to neutral, with PH test paper to determine the PH value of 6 ~ 7.

5, after the completion of the cleaning can be started to run. You can also pressurize the test to see if there is leakage. If there is a leak, you can use Megawatt polymer composite materials to repair and protect, and can greatly extend the service life of the equipment.

6, after the equipment is stabilized, note down the current medium over flow, working pressure, heat transfer efficiency and other data.

7, compare the cleaning and cleaning before the change in value, you can calculate the enterprise every hour to save electricity, coal and other production costs and improve efficiency.
