Description
Technical field
The utility model relates to a kind of air filter, and especially a kind of combination type air filter that is applicable to air conditioner ventilating system belongs to the air purifying process field.
Background technology
The traditional filtrate formula filter of the normal employing of the medium air filtration section of air purification field at present; Filtrate formula filter comprises bag filter, baffle filter is arranged and does not have baffle filter etc. that these traditional filtrate formula filter resistances are high, can cause the corresponding increase of system energy consumption; And the dust-filtering effect between 0.1 μ m～0.3 μ m is not remarkable; In use, when the forward and backward differential pressure of filtrate reaches the whole resistance of design, the filter that need more renew; Used filter is taken as rubbish, causes handling problem.In 2011 03 year 30 days, the Chinese patent of application number 201120087715.7 disclosed a kind of air cleaner, mainly is made up of casing and ionisation chamber to above problem applicant.Understand according to the applicant, above-mentioned filter has the gone into lung particle PM2.5 of harm to have good filter effect to health and atmosphere quality.Problems such as if think further to improve the filter efficiency of filter, dual mode is arranged at present: a kind of is the high efficiency particulate air filter that uses on the market, and this filter exists cost high, and energy consumption is big; Another kind is the twin-stage electrostatic filter that two electrostatic filter stacks are formed, and this twin-stage electrostatic filter not only initial stage input cost improves, and the ozone amount of its generation also can correspondingly increase.Therefore press for the filter of a kind of filter efficiency height, energy-conserving and environment-protective.
The utility model content
The purpose of the utility model is: the problem to above-mentioned prior art exists, a kind of good filtration effect is proposed, and have cost advantage, the combination type air filter of energy-conserving and environment-protective.
In order to reach above purpose; The combination type air filter of the utility model comprises complete machine outside framework and the ion chamber that is installed in the complete machine outside framework, and said complete machine outside framework one side end face is provided with air inlet; The opposite side end face is provided with air outlet; Its improvements are, preposition prefilter is set between the air inlet of said complete machine outside framework and the ion chamber, between the air outlet of said complete machine outside framework and the ion chamber bag filter are set.
The utility model further improves, and said complete machine outside framework is made by the panel beating moulding, is provided with the electrical equipment fixed head in the said complete machine outside framework, and the below of said electrical equipment fixed head is provided with ion chamber.
The utility model further improves again; Said ion chamber comprises support frame and is installed in the conductive contact member on the support frame; Said ion chamber is provided with ionized region and dust collection section successively along airflow direction, and said dust collection section is provided with the also positive and negative parallel-plate of line interlacing.
It is that said bag filter is made up of metal framework and the filter bag that is installed on the metal framework that the utility model further improves again.
Further perfect of the utility model is that said complete machine outside framework, ion chamber and preposition prefilter are formed electrostatic filter.
The advantage of the utility model is: the combination type air filter of the utility model adopts the technical scheme of electrostatic filter and bag filter combination; Not only prolonged the service life of bag filter greatly; Especially remarkable to PM2.5 particulate filtration efficient; Also can prevent the reentrainment of dust problem effectively; The present technique scheme has the advantage that suppresses ozone for the technical scheme of twin-stage electrostatic filter, and the present technique scheme has advantages such as lower resistance, low energy consumption and saving cost of investment joint for adopting high efficiency particulate air filter filtration PM2.5.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the fundamental diagram of the utility model.
The specific embodiment
Embodiment one
The combination type air filter of present embodiment; Its structure is as shown in Figure 1; Comprise complete machine outside framework 3 and the ion chamber 2 that is installed in the complete machine outside framework 3, complete machine outside framework 3 one side end faces are provided with air inlet, and the opposite side end face is provided with air outlet; Preposition prefilter 1 is set between the air inlet of complete machine outside framework 3 and the ion chamber 2, between the air outlet of complete machine outside framework 3 and the ion chamber 2 bag filter 4 is set.Wherein, complete machine outside framework 3, ion chamber 2 and preposition prefilter 1 are formed electrostatic filter, and complete machine outside framework 3 is made by the panel beating moulding and is furnished with electric standing part; Be provided with the electrical equipment fixed head in the complete machine outside framework 3; The below of electrical equipment fixed head is provided with ion chamber 2 (being ionization/collecting unit of dust), and ion chamber 2 comprises support frame and be installed in the conductive contact member on the support frame that ion chamber 2 is provided with ionized region 21 and dust collection section 22 successively along airflow direction; Dust collection section is provided with the also positive and negative parallel-plate of line interlacing; Bag filter 4 is made up of metal framework and the filter bag that is installed on the metal framework, and the material of filter bag is a chemical fibre, and metal framework is iron sheet frame or zinc-plated frame.
During actual the use, combination type air filter whole machine installation in the air channel, is passed to 220V, the 50Hz power supply places " ON " state with the ON/OFF switch on the filter panel, makes electrostatic filter and bag filter operate as normal.Dust-contained airflow at first passes through preposition prefilter 1, catches the large particulate matter in the air-flow, like hair, fiber etc.; Follow airflow passes ion chamber 2; Form a large amount of positive and negative ion in the ionized region of ion chamber 2, because of adopting positive corona, flowed to the positive corona utmost point and be neutralized by the negative aeroion of ionization (comprising free electron); The remaining cation in most of zone in the electric field, the collision of particles suspended and cation has been loaded positive charge in the air-flow; The grain flow that loads positive charge is to dust collection section, and voltage across poles is identical with ionized region voltage in this zone, because the same sex is repelled each other; The principle that there is a natural attraction between the sexes; Charged particle has been adsorbed the bacterium and the virus that are attached on the particle simultaneously by the absorption of the parallel-plate of heteropolarity, plays airfiltering effect; Most dust granules are hunted down in ion chamber 2, and the charged particle thing that minority is not adsorbed behind the arrival bag filter 4, is collected by pocket type filter 4.
Except that the foregoing description, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
