Description
Technical field
The present invention relates to a kind of electric bag combined dust catcher, it comprises electrostatic precipitation unit and bag-type dust unit.
Background technology
Electric bag combined dust catcher is widely used in the industries such as electric power, building materials, iron and steel, chemical industry, papermaking, food at present.Electric bag combined dust catcher comprises electrostatic precipitation unit and bag-type dust unit, and these two unit are connected as a whole.During electric bag combined dust catcher work, ash-laden gas at first directly enters its inside from the import of electrostatic precipitation unit, the charged back of grit is under the effect of electric field force, tend to gather dust electrode, the electrode that gathered dust captures, enter in the bag-type dust unit through the flue gas behind the electrostatic precipitation, the clean gas behind the cloth bag filtration enters air-purifying chamber and discharges from air outlet by exhaust blower again.Because the flue gas that directly enters into the electrostatic precipitation unit is concentration and temperature height not only, and dust specific resistance is also big, this had both influenced efficiency of dust collection, had shortened the service life of bag-type dust unit cloth bag again.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of electric bag combined dust catcher, and it is the efficiency of dust collection height not only, and prolongs the service life of bag-type dust unit cloth bag.
In order to solve the problems of the technologies described above, a kind of electric bag combined dust catcher of the present invention, it contains electrostatic precipitation unit and bag-type dust unit, these two unit connect in aggregates, also contain the flue gas conditioning system, this system is by housing, the atomized water spray device, current equalizer and rhone are formed, the rear end of housing is arranged on the front end of described electrostatic precipitation unit and communicates with it, the front end of housing is provided with air inlet, current equalizer is made of two groups of homogenizing plates and flow plug, two groups of homogenizing plates are perforated plate construction, flow plug is made of framework and some spoilers, on some spoilers divide, following two ones, the spoiler on top equidistantly is arranged on from top to down in the framework and with horizontal plane and is inclined to identical angle, the spoiler of lower part and the spoiler on top are symmetricly set in the framework, two groups of homogenizing plates are successively set on the interior rear portion of housing, flow plug is arranged in the housing and between two groups of homogenizing plates, the atomized water spray device is made of water inlet pipe support and shower nozzle, the water inlet pipe support is made up of horizontal water inlet pipe and some vertical water inlet pipes, some vertical water inlet pipes vertically are distributed on the below of horizontal water inlet pipe, its upper end is arranged on the horizontal water inlet pipe and communicates with it, its lower end sealing, uniform several described shower nozzles on every vertical water inlet pipe, the part that vertical water inlet pipe of the water inlet pipe support of atomized water spray device is equipped with shower nozzle is positioned at housing and is positioned at the leading section of housing, its horizontal water inlet pipe is positioned at the outside of housing, and rhone is positioned at the below of housing rear end.
Described vertical water inlet pipe has 13, wherein respectively is provided with nine shower nozzles on vertical water inlet pipe of both sides, respectively is provided with 18 shower nozzles on other vertical water inlet pipe.
Because the front end in the electrostatic precipitation unit is provided with the flue gas conditioning system, be provided with atomized water spray device and current equalizer in the housing of this system, when flue gas when the air inlet of housing front end enters in it, flue gas at first contacts with the water smoke of atomized water spray device ejection, it is wet that dust in flue gas becomes, its weight increases, wet dust bigger in the flue gas drops to housing bottom greatly because of weight, discharge after entering rhone along the bottom, kind of dust is reduced like this, helps improving the efficiency of dust collection of electrostatic precipitation unit and bag-type dust unit; It is wet that dust in flue gas becomes, and improved dust specific resistance greatly, and this helps improving the efficiency of dust collection of electrostatic precipitation unit; It is wet that dust in flue gas becomes, and flue-gas temperature is reduced greatly, and this has prolonged the service life of bag-type dust unit cloth bag.When flue gas passes through current equalizer, the homogenizing plate that is positioned at the front portion in a part of dust in the flue gas and this device hits and bumps, lose the bottom that falls into housing behind the kinetic energy, enter rhone discharges along the bottom, this has further reduced the dust concentration of flue gas, the through hole of another part dust in this homogenizing plate in the flue gas moves backward, at this moment the size of the airflow direction of flue gas and flow velocity is under control, when flue gas passes through the flow plug of current equalizer, spoiler in dust in flue gas and this flow plug hits and bumps, lose the bottom that falls into housing behind the kinetic energy, this makes exhaust gas dust concentration obtain reduction again, flue gas by the gap between the spoiler continues motion backward, when being positioned at the homogenizing plate at rear portion, a part of dust in the flue gas and this plate hit to bump and lose the bottom that falls into housing behind the kinetic energy, enter rhone discharges along the bottom, another part dust in the flue gas is by the through hole in this plate, the airflow direction of flue gas and the size of flow velocity have obtained further control, and flue gas continuation at this moment is moved into the electrostatic precipitation unit backward and the bag-type dust unit carries out dedusting.In sum, flue gas is by after the flue gas conditioning system, and the concentration of flue gas, temperature and dust specific resistance have all obtained reduction, and this has not only improved efficiency of dust collection, and has prolonged the service life of bag-type dust unit cloth bag.
