Abstract
The utility model relates to a filter for oil slag containing effluent, and pertains to the technical area of treatment of iron scale, slag and effluent produced in the steel rolling or the continuous casting. The traditional way of filtering always adopts the quartz sand filter which is prone to produce sticky oil mud to cause condensation and jamming in the filter to disable the filter and make the quality of the water after treatment, and then effects the normal production. So the filter for oil slag containing effluent is designed to be composed of a water inlet pipe, a water inlet filter pipe member, a tube, a stirrer, a guide plate, the filter material made of walnut shell, a water outlet filter plate member, a water distributor for backwash, and a water outlet pipe. The tube is a vertical cylindrical tube. In the upper seal head member of the tube, the sewage to be treated flows into the water inlet pipe to flow through the filter pipe member. The stirrer, the guide plate and the filter material made of walnut shell are arranged in the tube. The water outlet filter plate member, the water distributor for backwash and the water outlet pipe are arranged in the lower seal head member of the tube. With the filter and filter material as designed in the utility model, the backwash and recycling are convenient, the operation cost is low, the administration is convenient, the effect in removing the oil and the slag is good, and is the ideal filter equipment for treating the oil containing effluent which is produced in the steel rolling and in the continuous casting.
Description
Technical field:
The utility model relates to a kind of oil-containing, slag effluent filter, the processing technology field of particularly metallurgical steel rolling, continuous casting oil-containing, iron scale impurity waste water.
Background technology:
The treatment process of domestic steel rolling (continuous casting) oil-containing, iron scale impurity waste water generally is that cooling back reuse is filtered in secondary precipitation, and its technological process is as follows: turbid loopback water → eddy flow well → second pond → quartz sand filtration device → cooling tower → reuse.
Filter and adopt common quartz sand or double filtering filter.And its filtrate backwash and regeneration needs chemicals treatment and air water backwash, because impurity such as the oil content that contains in the sewage, scum skin, silt particle, easily form " greasy filth " with viscosity, the original filtration is to remove impurity such as oil content, scum skin, silt particle, because adhering to, greasy filth cause filtrate to harden, stop up and lose filtration on the quartz sand filter media, cause the water treatment water quality deterioration, oil-polluted water is among the vicious circle, thereby cause water treatment subsequent handling cooling tower to adhere to the tower that collapses because of greasy filth, greasy filth stops up steel rolling (continuous casting) cooling water nozzle, influences product quality.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned quartz sand filtration device processing oil-polluted water and exists " greasy filth " phenomenon to cause filtrate to harden, stop up the shortcoming that loses filtration, designs a kind of oil-containing, slag effluent filter
According to physical chemistry agglomeration principle of dynamics: finely divided oil droplet is to filtering the size of filtrate medium agglomeration power (F) in the water, depend on the tension force (σ) between oil bead diameter in the water (γ) and oil-water two-phase interfaces, and be following relation: F=4 π γ σ, by following formula as seen, oil bead diameter in the water (γ) is big, and the tension force between oil-water two-phase interfaces (σ) is big.
The characteristic of walnut shell filtering material: 1. have hydrophilic not oleophylic and suitable proportion, backwash is easy, and regeneration power is strong.2. have many ribs property and microporosity, section dirty power is strong, oil and suspended substance removal rate height.3. have many ribs property and different-grain diameter, form deep-bed filtration, strengthened oil removing ability and filtering velocity.4. hardness is big, and not perishable through specially treated, need not change filtrate, and an annual replenish lost amount is saved maintenance cost and maintenance time, increases operation rate.Walnut shell filtering material oil removing mechanism: the 1. cohesion between a filtrate material: suspension in the sewage and oil are adsorbed on the condensation product of filter material surface or filter material surface during with the filtrate collision.2. filtrate interception function: utilize filtrate to pile up and the filter bed that forms, a material of the suspension solid in the sewage is tackled in filter bed.Design a kind of steel rolling (continuous casting) oil-containing sewage filter of forming by cylindrical shell, upper cover, low head, water inlet screen casing, water outlet sieve plate, deflector, walnut shell filtering material etc.
Oil-containing, the slag effluent filter of the utility model design are mainly realized by following structure.
It mainly is made up of water inlet pipe (1), water inlet screen assembly (3), cylindrical shell (4), agitating device (5), deflector (6), walnut shell filtering material (7), water outlet sieve plate assembly (8), backwash water dispensing apparatus (10), outlet pipe (12); It is characterized in that cylindrical shell (4) constitutes by being upright cylindrical shape, in the upper cover assembly of cylindrical shell (4), water inlet pipe (1) injects cylindrical shell (4) by screen assembly (3) with treatment sewage; Agitating device, deflector (6), walnut shell filtering material (7) are housed in cylindrical shell (4); In the low head assembly of cylindrical shell (4), water outlet sieve plate assembly (8), backwash water dispensing apparatus (10), outlet pipe (12) are housed.
Described walnut shell filtering material (7) is tiled in level on the water outlet sieve plate assembly (8) that is provided with, and agitating device (5) comprises blade and rotating shaft, and blade is fixed on roller end, and described blade is arranged in the filtrate.Described rotating shaft and blade have two covers, and the rotating shaft level is to setting, and two rotating shafts and blade present the center symmetric arrangement, and the rotating shaft root stretches out outside the cylindrical shell.Water inlet pipe is arranged on the upper cover assembly, and outlet pipe is arranged on the low head assembly of water outlet sieve plate assembly below.
The oil-containing of the utility model design, slag effluent filter mainly are made up of water inlet pipe, upper cover assembly, low head assembly, water inlet screen casing, cylindrical shell, agitating device, deflector, walnut shell filtering material, water outlet sieve plate, sieve plate support frame, backwash water dispensing apparatus, outlet pipe etc.
This steel rolling (continuous casting) oil-containing sewage filter is to utilize physical chemistry agglomeration principle of dynamics, and utilization is through the characteristic of the wild walnut shell filtering material of specially treated, the oil-containing sewage filter of new generation that research and design goes out, it is compared with the quartz sand filtration device, maximum characteristics are exactly that the filtrate backwash and regeneration is convenient, can directly take to filter preceding backwash, need not by source of the gas and chemical agent, operating cost is low, convenient management, backwash intensity is low, oil removing, SS is effective, is to handle to substitute stone cottonrose hibiscus sand filter in steel rolling (continuous casting) oil-polluted water, increase water quality, simplify filtering technique, reduce the desirable water treatment facilities of cost of water treatment.
