Description
Technical Field
The utility model belongs to the technical field of the oil mist collector, concretely relates to can keep the effective absorption amount of wind to carry out the oil mist collector of effective absorption processing to the pollution sources invariably automatically continuously.
Background
The oil mist collector is an environment-friendly device which is mainly used for discharging relatively clean air from the tail part after mist of oil mist, oil smoke, water mist and micro dust mixed generated during the operation of metal processing equipment is treated in modes of absorption, trapping, separation, filtration and the like. The mechanical separation type oil mist collector sequentially separates all particles which can be collected and separated and are contained in oil mist through various elements with front-stage and middle-stage gas-liquid separation technologies, namely, various particles with the particle size of more than 0.5um and inertial motion characteristics are separated and processed through various gas-liquid separators, and the particles with the particle size of less than 0.5um are difficult to directly separate through the gas-liquid separators because most of the particles are in a random diffusion motion state, and need to be combined with a fiber cylindrical filter with corresponding filtering capacity for the tiny particles to carry out post-stage collection; the mixed oil mist gas is actively dredged and separated by the gas-liquid separators of the front stage and the middle stage in sequence, the mixture and the gas state which are liquid or contain partial solid are respectively separated and not mixed, the gas which is pushed backwards does not contain or only contains little separated liquid mixture, the post-stage cylindrical filter mainly filters the superfine oil mist and water mist particles which can not be separated and processed by the front stage, and the post-stage treatment quantity is much smaller in quality analysis.
In recent years, due to the layer-by-layer breakthrough and innovation of the gas-liquid separation technology of the oil mist collector, the technologies of various front-stage and middle-stage gas-liquid separators are effectively applied, and the most direct result is that compared with the past that the replacement time of a rear-stage cylindrical filter is shortened from 1 year 4 times to 1 year 1 time or less, but even if the rear-stage cylindrical filter is replaced 1 time in 1 year, the real problem that the rear-stage cylindrical filter is very wasted is solved, and the rear-stage cylindrical filter is usually expensive. As shown in fig. 1, the length of the effective operation time of the oil mist collector mainly determines the effective absorption air volume value of the oil mist collector, for example, 1 machining center generates a large amount of oil mist pollution during working, and the oil mist will pass through the gap of the machining center and be dissipated outwards when the closed door is opened every time to form air pollution without any treatment measures, and if the oil mist collector is selected and matched with 1 oil mist collector with power of 0.37kw and maximum absorption capacity of 20 cubic meters per minute according to the reference factors such as oil mist forming space of the internal cavity of the machining center, door opening times per minute, material property of the machined part, spindle rotation speed and the like, the following phenomenon will occur when the oil mist collector with exhaust gas emission purification efficiency of 99% for 0.4um particles is correspondingly collected and processed; the oil mist is absorbed particularly rapidly in the initial use, because the absorbed air volume is in a state close to the maximum value, the absorption speed is gradually reduced along with the increase of the operation time, the air volume is reduced, the oil mist particles are continuously gathered into liquid, the air permeability of a rear-stage cylindrical filter is inevitably influenced, when the oil mist collector operates for 8 months, the actual absorbed air volume is reduced to 8 cubic meters per minute and still stays within the effective absorbed air volume value, because the oil mist in the machining center can still be effectively absorbed by the oil mist collector, only the absorption speed changes, the oil mist pollution is still effectively controlled in an equipment cavity to be collected but not dissipated outwards, but when the oil mist is lower than 8 cubic meters per minute, the oil mist cannot be completely and effectively absorbed, and the absorbed air volume of 8 cubic meters per minute is the critical node of the effective absorbed air volume and the ineffective absorbed air volume in the embodiment, below this value, although a part of the oil mist can be absorbed, the existing part of the oil mist starts to be dissipated to the outside, and the more the amount of the oil mist is reduced, the more the oil mist is dissipated to the outside, and even when the oil mist collector is in operation, the oil mist collector is in a state of being substantially ineffective in absorbing treatment, and the pollution source starts to pollute and affect the surrounding environment.
The source part which causes the whole absorption air volume of the collector to be reduced is a rear-stage cylindrical filter, the front-stage and middle-stage separators have active separation characteristics and basically cannot cause too large influence on the air volume, the rear-stage cylindrical filter is mainly used for collecting oil mist and water mist particles with the particle size smaller than 1um, the rear-stage cylindrical filter adopts fiber non-woven materials with non-hydrophilic and non-oleophilic characteristics and high-efficiency filtering capacity, the fibers are densely and disorderly overlapped and formed, such as polyester fibers, metal fibers, glass fibers, polypropylene fibers and composite fibers formed by compounding various materials, the formed structure is compact and firm, the filtering material can meet the design requirement by being folded into a W-shaped continuous structure, has certain external force impact resistance, and the oil mist and water mist particles with the particle size smaller than 1um, particularly smaller than 0.5um, mainly do irregular diffusion movement, when the particles move from the peripheral layer of the cylindrical filter to the inner space of the cylinder, the particles can randomly collide with each fine fiber from outside to inside and are stopped, the gas bypasses and passes through the tiny gaps among the fibers to complete filtration, the tiny particles are numerous although small in number, a large number of particles can be orderly coagulated and retained in the peripheral structure layer of the cylindrical filter, the peripheral framework layer of the filter material and the fiber gap space of the layers in the outer-in direction by the gathered liquid, large liquid drops, small liquid drops, large particles and small particles in a step shape after continuous operation for months, the tiny fiber gap space only contains the liquid drops, the fibers do not absorb the liquid, and the fiber gaps in the outer-in direction are more and more in a transparent state which is not filled by the liquid particles, so that the functions of intercepting fine particles and permeating gas are maintained, when the liquid amount is more and more, the air permeability of the filter is reduced, the effective absorption air volume of the oil mist collector is gradually reduced to the invalid absorption air volume numerical range, and the pollution source cannot be effectively absorbed and is diffused to the surrounding environment.
Generally, liquid trapped and gathered by a rear-stage cylindrical filter is removed in an inside-to-outside back-blowing mode through high-pressure gas in the prior art, the back-blowing gas can penetrate through the cross section of the whole filtering material from inside to outside, the original gap between fibers can be torn and cracked under the action of high pressure, and the original structure of the filtering material of the filter can be damaged to bring adverse effects. In addition, another treatment mode for effectively absorbing the air volume reduction of the oil mist collector in the prior art is as follows: the maintenance indication mark is arranged on the oil mist collector, when the air volume is reduced to a value, the action of manually maintaining, cleaning and replacing the filtering material is prompted, but in the actual use, a plurality of users still have difficulty in timely paying maintenance and replacing the rear-stage cylindrical filter, the maintenance indication needs to pay close attention from time to time, when the user without the prepared filtering material prepares the material, a corresponding time period is also needed, and moreover, each replacement represents double cost investment of labor hour and material, the user can form a mind state of temporarily and regrettably continuing to use, even if the user does not use at all, and meanwhile, due to frequent investment of continuous operation cost, some psychological reluctant facilities are generated to maintain and replace, all operations to be completed need to be carried out by people, and are restrained and restricted by various practical factors in the actual use, the results are not ideal.
