Abstract
The utility model relates to a sodium sulfite-drying air flow filter. A front primary-effective filter layer is vertically arranged at an air inlet, a first-stage chemical filter layer and a second-stage chemical filter layer are horizontally arranged after the front primary-effective filter layer, a rear primary filter layer, a rear medium-effective filter and a rear high-effective filter layer are sequentially vertically arranged after the two stages of chemical filter layers, and an air outlet is arranged after the rear high-effective filter layer. Aimed at the acidic gases in the air, the sodium sulfite-drying air flow filter adopts two stages of chemical adsorption to clean the air, the first stage of chemical filtration is used for removing SOx and NOx in the air, and the second stage of chemical filtration is used for removing C12 and other gaseous acidic pollutants in the air. When the air passes through corresponding sorbent, the gaseous pollutants are first adsorbed in the sorbent to chemically react with active substances in the sorbent and be converted into relatively stable substances, and thereby the air is purified. The sodium sulfite-drying air flow filter is easy to mount and convenient to maintain, and can be overhauled on line.
Description
Technical field
The utility model relates to the air filtration technology, is a kind of sodium sulfite oven dry airflow filtering device that can remove solid particulate matter and sour gas in the air specifically.
Background technology
Produce in the anhydrous sodium sulfite process, the anhydrous sodium sulfite crystallization after the centrifugation in the bake drying device, needs to feed the air after filtering, to take away heat and moisture.Usually filtered air mainly uses bag filter to filter, and mainly is configured with inlet duct, filter bag, back-blowing device, gas storehouse lift valve, ash-discharging device composition.Owing to can cause the secondary of dust on filter bag to adhere in the bag filter blowback process, influence filter service life, and this filter can not remove airborne sour gas, be prone to cause getting into the decline of anhydrous sodium sulfite grade.
Summary of the invention
In order to solve the problem that the bag filter time between overhauls(TBO) is short and can not remove sour gas, the utility model provides a kind of can not only remove airborne solid particulate matter, and can remove the sodium sulfite oven dry airflow filtering device of airborne sour gas.
The utility model solves the technical scheme that its technical problem adopted:
A kind of sodium sulfite oven dry airflow filtering device; Comprise filter, air inlet and air outlet; Said filter comprises: the preposition primarily efficient filter layer that vertically is located at the air inlet place; The back level of said preposition primarily efficient filter layer is provided with one-level chemical filtering layer; Said one-level chemical filtering layer lower end is provided with secondary chemical filtering layer, and the rear end of said two-stage chemical filtering layer vertically is provided with rearmounted primarily efficient filter layer, rearmounted medium air filtration layer and rearmounted high efficiency filter layer successively, and said rearmounted high efficiency filter layer rear end is air outlet.
Effect, rearmounted efficient each filter course one side are separately installed with voltage drop meter in described preposition effect just, two-layer chemical filtering, rearmounted just effect, the postposition.
Said air cleaner is provided with 2 access doors.
Said air cleaner upper end is provided with charge door.
Described air inlet adopts louver structure.
Described air outlet adopts flange arrangement, is connected with the intake stack of air compressor machine.
The utility model is to airborne sour gas, and the mode through the two-stage chemisorbed cleans air, and first order chemical filtering is used to remove airborne SOx, NOx, and second level chemical filter is used to remove airborne Cl
2And other gaseous acid contact scar thing.When the corresponding adsorbent, gaseous contaminant at first is adsorbed in the adsorbent at air, carries out chemical reaction with wherein active material, converts metastable material to, thereby reaches the purpose that purifies air.The utility model is installed simple, and is easy to maintenance, can realize the on-bne repair of filter.
