Abstract
The invention aims to provide a method and a device for recycling oil refining wastewater. The method comprises the following steps of: 1) filtering oil refining wastewater which is discharged from an oil cleaning device by using a filtration device to obtain filtered oil and water; 2) filtering the filtered oil and water by using an oil-water separator to obtain recovered filtered water; and 3) performing pumpback on the filtered water so that the filtered water enters the oil cleaning device for recycling. The device comprises an oil cleaning tank and a water storage device, wherein the oil cleaning tank is connected with the water storage device through a water pipe; the filtration device and the oil-water separator are sequentially arranged in the water storage device from top to bottom; and the lower part of the oil-water separator is provided with a recovery water tank. The oil refining wastewater is filtered and catalyzed and then is pumped back into an oil refining device for further recycling. The water consumption for oil refining, particularly oil cleaning can be greatly saved, the production cost is saved, and the discharge of sewage is reduced.
Description
Technical field: the present invention relates to a kind of cycling utilization of wastewater method and device, particularly refinery water recycle method and device.
Background technology: prepare in the production process of oil fuel or industrial chemicals product at petroleum refining, need to use a large amount of water, so promptly have a large amount of trade effluents or sewage and produce, thereby very easily environment is polluted.As being that raw material prepares in the process of diesel oil or kerosene with oil fuel, particularly can produce a large amount of waste water during washing oil, promptly produce a large amount of waste water or sewage; Wherein, be nearly 1/3rd of washing oil amount with the waste water that produces in the washing oil production process.That is to say that the washing oil water is 30 percent of a washing oil amount.If washing oil exhausted water directly effluxed promptly environment is polluted, and consumed great amount of water resources.Simultaneously, the waste water that produces is not done recycling utilization, the waste water of loss also can be taken away the part oil product, causes the waste of the resource of oil product.
At present, also good without comparison way is carried out cyclic utilization method to the waste water that produces in oil refining, the washing oil process.
Summary of the invention:The present invention will provide a kind of refinery water recycle method and device exactly, be with refinery water after filter handling, handle further recycle in pumpback to the oil refining apparatus again through catalyst.Can practice thrift in a large number and refine oil particularly washing oil water consumption, save production cost, reduce sewage emissions.
A kind of refinery water recycle method is characterized in that carrying out as follows:
1), the washing oil waste water that will from Device for washing oil, give off, with filtration unit the oil refining catalyst in the washing oil waste water is carried out filtering, must filter profit;
2), will filter profit through the water-and-oil separator filtration treatment, establish the profit filtermedium in the described water-and-oil separator, must reclaim filtered water;
3), with filtered water, in pumpback gets into Device for washing oil, recycle.
Profit filtermedium of the present invention is any mixing of thin charcoal, molecular sieve, fine sand or three.
A kind of device of realizing above-mentioned refinery water recycle method; Comprise oil-washing tank, water storage device, oil-washing tank is connected with water storage device through water service pipe; Be provided with filtration unit and water-and-oil separator in its described water storage device from top to bottom successively, the water-and-oil separator bottom is provided with the recovery tank; Described water-and-oil separator is provided with the profit filtermedium.
Filtration unit of the present invention is a 100-120 order filter screen; Said water-and-oil separator is a 160-180 order filtering net.
The present invention's a kind of refinery water recycle method and device, the consumption of conserve water resource in a large number in the oil refining production process saves production cost, and the discharging for oil refining enterprise minimizing waste water alleviates the pollution to environment.In general oil refining process, the waste water that has usually about 4% produces, and also has nearly about 3% grease foreign material, follows waste water and runs off.The washing oil water consumption is 1/3rd of a washing oil amount; As in every day refinery output at 40 tons, nearly 14 waste water that ram the loose soil with a stone-roller after sowing and nearly waste oil waste loss more than 1.5 tons are just arranged every day.Also the loss of taking out more than the 10 ton of many electricity consumptions of process water to be arranged.Therefore, behind employing the inventive method and the device, by can practice thrift nearly 300 tons of process water in every month in above-mentioned refinery output, nearly 50 tons of the grease fuel of recovery generation and utilization has bigger economy, society and environmental benefit.
Description of drawings:
Fig. 1: be cycling utilization of wastewater device synoptic diagram of the present invention.
Among the figure: 1, oil-washing tank, 2 aqua storage tanks, 3, the filtration unit net, 4, water-and-oil separator, 5, water pump, 6, the profit filtermedium, 7, stopping valve, 8, water service pipe, 9, reclaim tank.
Embodiment:Below in conjunction with specific embodiment the present invention is done further detailed description.
Embodiment 1
The oil-washing tank 1 that above aqua storage tank 2, is provided with as shown in Figure 1 is provided with a water service pipe 8 in the bottom of oil-washing tank 1 and is communicated with aqua storage tank 2, on water service pipe 8, is provided with stopping valve 7, flows in the aqua storage tank 2 with oil in the control oil-washing tank 2; The water outlet of water service pipe 8 is located at the top of aqua storage tank 2, is positioned at the top of filtration unit net 3; In aqua storage tank 2,, be provided with filtration unit net 3 and water-and-oil separator 4 successively from top to bottom, reclaim the bottom that tank 9 is located at aqua storage tank 2.3 pairs on filtration unit net is emitted from oil-washing tank 1, and the large granular impurity in the oil product filters, and it mainly is to filter in refining, the washing oil process to add catalyzer.Said filtration unit net 3 is 120 eye mesh screens; Described water-and-oil separator 4 is 180 order filtering nets; On profit water sepn 4, be provided with profit filtermedium 6; Said profit filtermedium is any one in thin charcoal, molecular sieve, fine sand, or three's the mixing of pressing arbitrary proportion; Water pump 5 is located at and is reclaimed tank 9 inner bottom parts.
Technological process is: from oil-washing tank 2 interior profit blended waste water of discharging; Filtration unit net 3 in water service pipe 8 is flowed through aqua storage tank 2; In 3 pairs of waste water of filtration unit net because of in the oil refining process, the washing oil granules of catalyst and the large granular impurity material of adding filter, and must filter profit; The profit filtermedium 6 of above-mentioned filter oil current on water-and-oil separator 4, i.e. charcoal or molecular sieve, fine sand, or the mixed catalyst of its three's arbitrary proportion; Also can be unslaked lime, carry out oxidation catalyst filter and become the recovery filtered water, reclaim filtered water and get into again in the recovery tank 9.To reclaiming the recovery filtered water in the tank 9, in water pump 5 suction oil-washing tanks 1, be used for the washing oil water.So promptly realized the recycle of waste water.
