When the main discharge method in the kitchen is open ditch, the diameter of the pipe is 150mm

1、 Pipe arrangement

Kitchen drainage pipes are mostly used for short distance connections between drainage points of equipment and facilities and nearby open ditches. Outside the

 kitchen, they are generally used for connecting indoor pipe networks with outdoor oil separators and municipal sewage pipelines.

When the main discharge method in the kitchen is open ditch, the diameter of the pipe discharge should be within 150mm, and the diameter of the outdoor 

sewage main pipe should not be less than 200mm.

2、 Ditch drainage

Open ditch discharge is the main way of sewage discharge in the kitchen. Each operation room or area is equipped with an open trench. The open ditch 

should be covered with cast iron or stainless steel grates, and the grates should also have movable stainless steel cover plates that can be picked up at any time.

The length of the open kitchen ditch should not exceed 30m, and the slope of the ditch bottom should be between 0.5% and 2%. The depth of the highest point (st

arting point) of the open ditch should be between 50-80mm, and the end of the open ditch should be equipped with sedimentation wells and anti rodent slag frames.

3、 Pool Drainage

When there are many devices, centralized drainage points, and a large drainage volume in a certain area of the kitchen, pool drainage can be considered, such as in the

 raw material rough processing room, tableware cleaning room, etc.

The method of pool drainage is to set up a floor pool below the kitchen floor level, and the size of the floor pool should include all drainage points in the area. The pool is

 connected to the open drainage ditch and a slag receiving basket is installed at the outlet.

The depth of the underground pool is generally between 80-200mm, which can be selected according to the construction site conditions.
