Cinder soaking water concentrating and separating tank

Abstract

The invention relates to a concentration and separation processing facility for flushing cinder soaking water from a fuel electric plant, in particular to a cinder soaking water concentrating and separating tank which is mainly characterized in that a separated tapered cinder hopper (14) of the concentration and separation tank is arranged below a concentration and separation tank body (1) and is internally provided with a cinder separating plate (15); the middle part of the concentration and separation tank body (1) is provided with a straight reaction cylinder (6) which is a reaction region A on the upper part, a rotational flow settling region B in the middle and a first concentration region C at the lower part; the outer wall of the straight reaction cylinder (6) is fixedly connected with a tapered reaction cylinder (9); the concentration and separation tank body (1), the separated tapered cinder hopper (14) of the concentration and separation tank and the tapered reaction cylinder (9) forms a second concentration region E which is connected with a second cinder discharging pipe (12) and a valve (13) arranged on the second cinder discharging pipe (12); a flow guiding cylinder (7) is arranged outside the straight reaction cylinder (6) and forms a flow guiding region D together with the straight reaction cylinder (6) and the tapered reaction cylinder (9); a tapered cinder baffle (8) is arranged on the concentration and separation tank body (1), and a separation region F is formed between the tapered cinder baffle (8) and the flow guiding cylinder (7).

Description

technical field [0001] The invention relates to a treatment facility for concentration and separation of ash flushing and slag water for a thermal power plant, and a treatment method using the concentration and separation treatment facility for ash flushing and slag wastewater of the invention. Background technique [0002] At present, some thermal power plants in my country still use low-concentration direct-discharge ash flushing systems, and large-flow, low-concentration mortars are directly discharged into ash yards. Due to the large amount of water discharged into the ash yard, which exceeds the evaporation and leakage of the ash yard, drainage outside the ash yard occurs. Water bodies discharged directly to the outside often pollute the environment. [0003] In order to save water and reduce external drainage, many thermal power plants send the overflow water from the ash field back to the power plant for recycling ash, realizing the recycling of ash water. However, ...

AI Technical Summary

Problems solved by technology

[0005] (1) Ash flushing consumes a lot of water;

[0006] (2) The amount of water discharged into the ash yard is large, resulting in external drainage;

[0007] (3) Long-distance transportation of large-flow mortar, high energy consumption,

[0008] (4) The thick slurry pipeline and the return water pipeline of the ash yard are relatively long, and the cost of scale prevention is high and difficult, which is not conducive to water reuse

The system still has the following deficiencies: (1) it occupies a large area; (2) it must have concentrating equipment, so the management and maintenance of mechanical equipment is complicated and the power consumption is large; (3) the pool body is low, which makes the concentrating effect somewhat (4) It is impossible to collect low-density hollow spherical ash particles in gray water, commonly known as "floating beads", which are a new type of building material
