Problems solved by technology
However, this kind of sludge treatment method has the following problems: ① The construction of sludge concentration tank, sludge filter press room and supporting equipment and facilities requires a large amount of capital investment, and the system construction cost is high; ② The sludge treatment system occupies a large area; ③The operation of the system consumes a lot of electric energy, so the operating cost is high; ④The iron scale wears out the equipment such as sludge pumps, pipes, and valves very seriously, so the maintenance frequency and workload of the equipment are large; Working under high-pressure conditions, plates, frames, filter cloths, etc. are easily damaged and need to be replaced frequently; ⑥The treatment process is long, and leakage often occurs during sludge transportation, concentration, treatment and equipment maintenance.

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] see figure 2 and image 3 , a kind of sludge treatment equipment for the turbid ring system of a hot rolling mill in an iron and steel enterprise, including a sludge treatment tank. The length of the sludge treatment tank is 15m, the width is 4m, and the height is 4m. This size can be appropriately scaled up or down, and the sludge The treatment pool is a reinforced concrete structure, the pool wall 1 is 20cm thick, and a steel plate 2 with a thickness of 5mm is laid on the bottom of the pool. The steel plate 2 is evenly arranged with water seepage holes 3, the diameter of the small holes 3 is 5mm, and the adjacent small holes 3 The gap between them is 5cm, and all the water that leaks out through the small holes 3 on the steel plate 2 can be collected and reused in the steel rolling turbid ring system, and the treated sludge can be used as sin...

Abstract
The invention relates to a kind of sludge treatment equipment and its treatment process in the turbid ring system of a hot rolling plant of an iron and steel enterprise, including a sludge treatment pool, the sludge treatment pool is a reinforced concrete structure, and a steel plate is laid on the bottom of the pool, and the steel plate is evenly arranged There are small water seepage holes, all the water that leaks out through the small holes on the steel plate can be collected and reused in the steel rolling turbid ring system, and the treated sludge can be used as sintering raw material, and a layer of iron oxide scale and sludge are laid on the steel plate The treatment tank is connected to the sludge storage tank that transports sludge to the sludge treatment tank through a sludge pump. The device is simple in structure, low in cost, very convenient in operation and management, occupies a small area, and does not need to build sludge concentration tanks, sludge filter press rooms, and supporting equipment and facilities, so it has the characteristics of greatly reducing the construction cost of sludge treatment systems .
Description
technical field [0001] The invention belongs to the technical field of sludge treatment equipment, and relates to sludge treatment equipment and a treatment process for a turbid ring system in a hot rolling plant of an iron and steel enterprise. Background technique [0002] see figure 1 , the sludge settled by the chemical degreaser in the turbid ring system of the existing iron and steel enterprise hot rolling plant enters the sludge tank, and then is stirred evenly by the agitator and then pumped into the sludge thickening tank with the sludge pump, and then the high-lift sludge is used to The pump is pumped into the plate and frame filter press, the sludge is dried and transported outside, and the filtered water is returned to the turbid ring system. However, this kind of sludge treatment method has the following problems: ① The construction of sludge concentration tank, sludge filter press room and supporting equipment and facilities requires a large amount of capital ...
