The kitchen drains in the hotel are all oily, how to dredge the blocked pipes?

Unclogging of sewers:

1. Animal fat blockage: If it is oily, it is recommended to use boiling water, of course, if you can buy concentrated sulfuric acid, the effect is better. If something is clogged, the only way to do that is to clean the pipes.

2. Cement plugging: 70% hydrochloric acid cannot be found, and 35% is sold everywhere, you can try it. Add a small amount of flour to it to act as a corrosion inhibitor, and it is best to have urotropine. It can reduce the corrosion of steel.

3. Go to the market to spend quick money to buy a 2-meter-long spring wire pipe dredging tool, bend 1-20 degrees at 1-2 cm on its head, dredge it back and forth at the entrance and exit of the sewer, and flush it with water.

4. Go to the mall to buy a powder that professionally cleans the pipes.

5. Put in a small yellow beetle, or add some irritating things such as washing powder or salt, and then cover the lid, and the sewer pipe will pass instantly.

6. Pour 1 cup of laundry detergent into the clogged drain, then pour 3 cups of hot water. If that doesn't clear the drain, pour 1 more cup of vinegar into it.

7. Insert a log with a diameter close to the inner diameter of the sewer pipe into the pipe, put a certain amount of water in the pool, and pump the log up and down quickly without interruption, and the clogged dirt in the pipe will be washed away under the action of suction and pressure.

The kitchen drain of the hotel is full of oil stains, and you should have discharged the untreated oily sewage directly into the sewer.

With the decrease of temperature, the waste grease condenses, and the grease adheres to the inner wall of the drain pipe, which causes the inner diameter of the drain pipe to decrease over time, resulting in the formation of blockage due to poor drainage, and the overflow of wastewater from drainage inspection wells, and the waste water breeds mosquitoes and flies in summer, infects diseases, and pollutes the environment with peculiar smells.

It is recommended to install an oil-water separation equipment, waste residue, waste oil, and waste water are discharged separately, which is conducive to improving the environmental sanitation of the kitchen, and can also be inspected by the environmental protection department.

The size of the grease trap mainly depends on the size of the hotel, the price is not very expensive, and the ordinary stainless steel grease trap has no operating costs, so there is no need to worry about additional electricity bills.

The unreasonable design and installation of smoke exhaust pipes often cause the kitchen smoke exhaust to be unobstructed, which directly affects the use of oil fume purifiers. The main reasons for this are as follows:

1. The ventilation area of the main smoke exhaust pipe is insufficient, and the gas flow rate is too large. According to the engineering experience, the wind speed in the main smoke exhaust pipe should not exceed 15m s. Otherwise, after a period of operation (such as a year after the town banquet), it is easy to cause the smoke exhaust system to be unsmooth.

In the operation practice of oil fume purifiers, most of the cases are caused by the lack of ventilation area of the exhaust pipeline, and the flow rate of the gas in the pipeline is more than 15m s.

2. The ventilation section of the smoke exhaust pipe becomes smaller because it has to pass through the building beam, and the resistance on the section increases, resulting in unobstructed airflow.

3. When the smoke exhaust pipe passes through the building beam or evades other equipment pipes, one section of the smoke exhaust pipe will be lower than the overall smoke exhaust pipe plane. After a period of use, the oil-water mixture will accumulate in the lower section of the smoke exhaust pipe, which directly affects the smooth flow of the smoke exhaust.

Fourth, the kitchen fumes on different floors are discharged through the same main pipe, and the kitchen smoke exhaust effect on the floor near the exit is better, while the kitchen smoke exhaust on the lower floor is not smooth.

Therefore, the following data should also be paid attention to in the design of kitchen smoke exhaust pipes:

1) The diameter of the tuyere of the oil fume purifier is 800mm

2) The distance between the rusty steel hood of ominous pants and the tuyere should be 4m
