Description
(1) technical field
The present invention relates to the dust removal by filtration technology, is exactly the supporting geomantic omen mist filtration, purification cleaner of a kind of and drying plant specifically.
(2) background technology
Cleaner refers to equipment that dust is separated from flue gas, the dust removal mechanism of cleaner is very simple, and it is the same with the dust removal mechanism of mouth mask, is by filtering material the machinery of fly ash granule in the flue gas to be tackled to realize.But in addition, the fly ash granule of receiving has earlier also formed the stable dense grieshoch (being commonly referred to as filter cake or filter bed) of one deck at filter material surface, it has played good filtration again, particularly makes the cleaner of filter bag of establishment cloth, and this metafiltration bed has played main filtration.Filter element can become filtrate through weaving (or acupuncture) by staple, glass fibre or various chemical fibre, is sewn into the filter bag of vertical hanging again.Remaining pressure loss of bag-type dust equipment is to be produced by flue and baffle door between the bag-type dust equipment importation flange.The size of this pressure drop and the flow velocity of flue gas square proportional, therefore the pressure drop Δ p. of whole bag-type dust equipment and the relation that exhaust gas volumn is quadratic power.The performance of cleaner with accessible gas flow, gas drag losses and the efficiency of dust collection during by cleaner express.Simultaneously, the price of cleaner, operation and maintenance cost, service life length and operational administrative difficulty or ease also be to consider the key factor of its performance.Cleaner mainly divides following a few class: (1) mechanical force cleaner comprises gravitational dust collection equipment, inertial dust collection equipment, centrifugal dust-removing equipment etc.(2) the washing type cleaner comprises water-bath type cleaner, foam type cleaner, Venturi tube cleaner, water film type cleaner etc.(3) the filtering type cleaner comprises (4) electrostatic dust collection equipments such as bag-type dust equipment and stratum granulosum cleaner.(5) magnetic dust removal equipment.
Inertial dust collection equipment is to make dusty gas and baffle plate bump or sharply change airflow direction, utilizes inertia force to separate and capture the cleaner of dust.Inertial dust collection equipment also claims the inertia cleaner.The performance of inertial dust collection equipment is different different because of structure.When the flow velocity of gas in equipment is 10m/S when following, the pressure loss is between 200 1 1000Pa, and efficiency of dust collection is 50% one 70%.In actual applications, inertial dust collection equipment generally is placed on the first order of Multilevel Dust Control System, is used for the thicker dust of separating particles.It is specially adapted to capture particle diameter greater than the dried dust of 10 μ m. remove caking property dust and fibre dust and be unwell to.Inertial dust collection equipment can also be used to separating droplet, and require the flow velocity of gas in equipment to be advisable with 1-2m/s this moment.The fountain cleaner is that water is by the nozzle atomisation in cleaner, and when ash-laden gas passed through vaporific space, because of the collision between grit and the drop, interception and cohesion, grit settled out with drop.This cleaner simple structure, resistance are less, easy to operate.Its outstanding advantage is to be provided with very little slit and aperture in the cleaner, can handle the higher flue gas of dust content and can not cause stopping up.Because the drop of its spray is thicker, so do not need vaporific nozzle, operation is more reliable so again, sprays beautiful jade formula cleaner and can use recirculated water, and particulate matter reaches till the quite high degree in washing lotion, thereby has simplified water processing establishment greatly.So this cleaner still has many enterprises to adopt so far.Its shortcoming is that equipment volume is huger, and the ability of handling fine dust is lower, so need water consumption often to be commonly used to remove the flue gas that dust size is big, dust content is high.Flow problem in cleaner is divided into three kinds of structures to fountain cleaner commonly used according to gas and liquid: (1) following current fountain, and namely gas flows with identical direction with water droplet; (2) countercurrent spray formula, namely liquid sprays against air-flow; (3) cross-flow fountain is namely spraying liquid perpendicular to airflow direction.
At present, flue gas is excessive in process of production for several brown coal drying and upgrading equipment that emerge both at home and abroad, and brown coal are through after the drying and dewatering, because brown coal are vegetation character, traditional several cleaners are all undesirable to the dust removing effects of the flue gas of its generation, dust, the requirement that does not reach low-carbon environment-friendly.
(3) summary of the invention
