Inclined plate settler for settling and separating coal slag water

Technical Field

The utility model relates to the technical field of industrial water treatment, in particular to an inclined plate settler for settling and separating coal slag and water.

Background

With the development of the project of producing olefin, oil, glycol, natural gas, arene, large synthetic ammonia, methanol and synthetic gas from coal in China. A large amount of coal slag water, which we generally refer to as "black water", will be produced in the coal gasification section. The amount of black water generated is about 10000 tons a day due to the large amount of black water, and the water is recycled for saving water resources. The conventional cinder water is naturally clarified by a clarifying tank and then recycled, but the water quality often does not reach the requirement of below 100ppm and can not be recycled.

At present, the following two water treatment processes are generally adopted in China to solve the problem of coal cinder water clarification:

the natural settling process adopts a structure that no inclined plate device is arranged in a tank body, and achieves the purpose of clarification by controlling the settling time of the stay, wherein the stay time is about 4 to 6 hours generally. After long-time stay, the treated water quality can meet the process requirements, but the tank body occupies a larger area and the slag water treatment capacity is smaller.

The natural sedimentation and inclined plate sedimentation combined process is characterized in that an inclined plate is arranged in an upper tank of the structure, a central water inlet mode is adopted, an inclined plate or an inclined pipe is paved at the upper part, the retention time is 3-4 hours generally, the treated water quality is good, but the investment cost is high, the amount of added flocculating agent is large, and the operation cost is high.

Detailed Description

The technical solution in the embodiment of the present invention will be made clear below with reference to the drawings in the embodiment of the present invention; the present invention has been described in considerable detail with reference to certain preferred versions thereof. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-2, in the embodiment of the present invention, an inclined plate settler for coal cinder water sedimentation separation, comprises an inclined plate settler 1, support profile steel 2, a collector 3 and a clear water outlet 4, the inclined plate settler 1 is installed in a clarification tank body 5 through the support profile steel 2 for installing in the clarification tank body 5 for sedimentation separation, the collector 3 is installed on the upper side of the inclined plate settler 1 for separating clear water after sedimentation, the clear water outlet 4 is installed on the lower side of the 3 one end of the collector, and the clear water outlet 4 runs through the side wall of the clarification tank body 5.

Preferably, the inclined plate settler 1 is of a PP (polypropylene) or stainless steel or glass fiber reinforced plastic structure, has high structural stability and is convenient to use for a long time.

Preferably, the inclined plate settler 1 consists of a plurality of groove-shaped inclined plates 101, and 60 degrees are arranged between the groove-shaped inclined plates 101 and the groove-shaped inclined plates 101, so that the fluid contact area and the slag water stroke are increased, and the retention time of the slag water is prolonged.

Preferably, the interval between the adjacent groove-shaped inclined plates 101 is 20-60mm, and can be adjusted according to the situation to prevent large-particle solids from blocking the channel.

Preferably, a slag water inlet is arranged at the lower side of the inclined plate settler 1, so that coal slag water to be subjected to sedimentation separation enters from the lower part of the inclined plate settler 1.
