Static composition metal filler wet dust removal filter and filter method
Technical field
The present invention relates to a kind of static composition metal filler wet dust removal filter and filter method, belong to air filtration, purification technology field.
Background technology
Air conditioner industry exists three challenges greatly at present: healthy, energy-conservation and environmental protection.Many in recent years studies show that, the atmospheric air quality allows of no optimist, and adds that the physics of some buildings self and chemical contamination, air conditioner fresh air amount are introduced deficiency and operation management is not good at, and causes indoor air quality to worsen.Exist harmful substances such as a large amount of aerosols, microorganism and chemical gaseous pollutant in the air, be detrimental to health and influence to produce and carry out.
Current air-conditioning system is generally used just, medium effeciency filter improves indoor air quality.But, just, medium effeciency filter is lower to 1 μ m and following aerosol filter efficiency; Simultaneously, the long-term use of filter caused filtration resistance increase, especially medium effeciency filter, and resistance increases severely, and causes the air-conditioning air quantity to reduce, and operating cost increases, and makes a lot of air-conditioning systems that roughing efficiency air filter only is installed, and medium effeciency filter is not installed; And; when air-conditioning box between the whole system down period; the condensed water that outdoor air infiltrates, the temperature inside the box gos up and accumulate constantly evaporates; for the microorganisms such as bacterium that are trapped on the filter are created desirable breeding environment; bacterium can produce multiple metabolin in reproductive process, as smell, toxin, allergin etc., the particle diameter of most of metabolins is very little; be easy to penetrate filter, cause the secondary pollution of air-conditioning system.
Summary of the invention
The invention discloses a kind of static composition metal filler wet dust removal filter and filter method, can overcome low, the drawbacks such as bacterium easily breeds, air secondary pollution of filter efficiency that existing air-conditioning system exists.The present invention is a kind of composite dedusting filter of novelty, is particularly useful for removing the pollutants etc. that easily condenses such as filtering high-temperature flue gas and mist of oil.Grit, microorganism can not be detained in metal packing inside, and the aerosol particles of above particle of 1 μ m and 0.5-1 μ m is all had high filtration efficiency, have guaranteed health.
Static composition metal filler wet dust removal filter, comprise: storage tank, water pump, rectification step-up transformer, high-pressure metal nozzle group, wavy metal filler, blower fan, tank and water fender, it is characterized in that: dust removal filter top built-in high-pressure metal nozzle group, high-pressure metal nozzle group water inlet external water pipe, water pipe is connected with storage tank through water pump; High-pressure metal nozzle group bottom is provided with the wavy metal filler, and water fender is installed in the air-out position of wavy metal filler, and the bottom of dust removal filter connects tank, and dust removal filter one end connects blast pipe, and corresponding end connects discharge pipe, described discharge pipe internal fan; The outer setting of dust removal filter has the rectification step-up transformer, and rectification step-up transformer and each nozzle of high-pressure metal nozzle group are connected in parallel by lead.
The filter method of static composition metal filler wet dust removal filter is: by high-pressure metal nozzle group with after the rectification step-up transformer is connected, form the tiny electrostatic charged spray of particle diameter, the droplet spray is at the charged moisture film of the inner formation of metal packing, charged moisture film and small dust produce image force, make grit humidification, cohesion and weightening finish and are hunted down; Big grit directly is filtered, detention.Captive grit flows into tank with sewage, reaches the effect of removing large and small grit in the air.
The present invention is simple in structure, and grit, microorganism can not be detained in that metal packing is inner, not avoid secondary pollution, and the aerosol particles of above particle of 1 μ m and 0.5-1 μ m is all had high filtration efficiency, has guaranteed health.Being particularly useful for removing the pollutants etc. that easily condenses such as filtering high-temperature flue gas and mist of oil, is the compound wet dust removal filter of a kind of auto purification type static.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is done and to describe in further detail.
Static composition metal filler wet dust removal filter, comprise: storage tank 1, water pump 2, rectification step-up transformer 3, high-pressure metal nozzle group 4, wavy metal filler 5, blower fan 6, tank 7 and water fender 8, its structure as shown in Figure 1, dust removal filter 11 tops built-in high-pressure metal nozzle group 4, high-pressure metal nozzle group 4 water inlet external water pipes, water pipe is connected with storage tank 1 through water pump 2; High-pressure metal nozzle group 4 bottoms are provided with wavy metal filler 5, water fender 8 is installed in the air-out position of wavy metal filler 5, and the bottom of dust removal filter 11 connects tank 7, and dust removal filter 11 1 ends connect blast pipe 10, corresponding end connects discharge pipe 9, described discharge pipe internal fan 6; The outer setting of dust removal filter 11 has rectification step-up transformer 3, is connected in parallel by lead with high-pressure metal nozzle group 4 each metallic nozzle.
By high-pressure metal nozzle group with after the rectification step-up transformer is connected, form the tiny electrostatic charged spray of particle diameter, droplet spray forms charged moisture film in that metal packing is inner, and charged moisture film and small dust generation image force make grit humidification, cohesion and weightening finish and be hunted down; Big grit directly is filtered, detention.Captive grit flows into tank with sewage, reaches the effect of removing large and small grit in the air.
The concrete course of work is as follows:
Water in the storage tank 1 is under the driving of water pump 2, through the high-pressure metal nozzle 4 that links to each other with rectification step-up transformer 3, form the less electrostatic charged spray of particle diameter, droplet forms charged moisture film in metal packing 5 inside under the gravity effect, blower fan 6 provides power to make to have the air of grit to enter dust removal filter 11 by blast pipe 10, new wind during through filler big grit contact with drop, liquid film by inertial collision, contact detention effect, mainly be hunted down by gravitational effect, the inertia effect and interception effect; Less grit and charged moisture film near the time, can produce the mirror image charge inducing, under the image force effect, make grit humidification, cohesion and weightening finish, mainly be hunted down by diffusion effect and electrostatic effect.Air is sent into indoor through behind the dust removal filter 11 by discharge pipe 9; The sewage of catching grit flows into tank 7 because the gravity effect, can be recycled after treatment or enters sewer.Blast pipe of the present invention, discharge pipe, dust removal filter and be connected high-pressure metal nozzle water pipe and must take insulation measures are avoided electric leakage.Experiment results shows: static composition metal filler wet dust removal filter of the present invention and filter method not only have very high filter efficiency to the above particle of 1 μ m, and the aerosol particles of 0.5-1 μ m are also had high filtration efficiency.
