The service life of device reduces maintenance cost.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this: a kind of rubbish
Rubbish burning waste gas degasification dust-extraction unit, uses vertical structure arranged up and down, including upright shell, upright shell is from top to bottom
Be divided into and denitrogenate room, dedusting enriched chamber, water tank, the dedusting enriched chamber be provided with air inlet, dedusting enriched chamber bottom be equipped with
It is lifted with integrated ceramic membrane mechanism inside screw ash-discharging device that the external world communicates, dedusting enriched chamber, is equipped with and removes inside the water tank
Sulphur room, the porous seat that sulphur removal room is fixed, the water tank top offer exhaust outlet, which is characterized in that denitrogenate chamber interior and be equipped with
SCR nitrogen oxides is nestled up on the left of low-temperature plasma mechanism and SCR nitrogen oxides catalysis restoring component, low-temperature plasma mechanism to urge
Change that restoring component, to offer the connecting pipe being connected with water tank, connecting pipe straight for SCR nitrogen oxides catalysis restoring component side
Logical sulphur removal room, denitrogenates room and ceramic membrane mechanism connection.Three chambers are arranged up and down reduces occupied area, can be dusted,
Sulphur removal and denitrogenating carries out together, further improves the standard of gas discharge.
Further, the integrated ceramic membrane mechanism shares 6, is located at the top inside dedusting enriched chamber, and three
Series connection is one group, and totally two groups, ceramic membrane covers the entire upper area of dedusting enriched chamber.Area of passage is increased, is met more
Air inflow.
Further, the air inlet is provided with dedusting enriched chamber side wall, and air inlet is directed at integrated ceramic membrane mechanism side.
Using blow-back ceramic membrane is entered, guarantee the cleaning of integrated ceramic membrane mechanism.
Further, the low-temperature plasma mechanism and SCR nitrogen oxides catalysis restoring component are mounted on and denitrogenate in the middle part of room,
The surface of integrated ceramic membrane mechanism.Filtered gas is set to no longer need to be directly entered removing nitrogen oxidation in the room of denitrogenating by pipeline
Object improves efficiency.
Further, the sulphur removal room is mounted on water tank bottom.It is designed using gas-lifting type chilling structure, allows the gas of entrance
It is come into full contact with liquid phase, improves sulfur removal effectiveness.
The utility model has the advantages that the utility model has the advantage that compared with traditional sight technology
1. being catalyzed restoring component and gas by adding integrated ceramic membrane mechanism, low-temperature plasma mechanism, SCR nitrogen oxides
The methods of lift-type chilling structure, so that the present apparatus becomes, a kind of processing exhausted air quantity is big, exhaust-gas treatment is thorough.
2. being arranged by air inlet in integrated ceramic membrane mechanism side, ash-removal effect is good, high dust collection efficiency, reliable for operation.
3. by dedusting enriched chamber, denitrogenating the arrangement up and down of room and water tank, the occupied area of whole device is reduced.
