Description
Technical field
The utility model relates to a kind of emission-control equipment, relates in particular to a kind of dry type emission-control equipment with fume recovery system, with the dust of automatic recovery dry type emission-control equipment generation.
Background technology
Usually, adopt the dry type emission-control equipment that the waste gas that various factories produce is handled, its adsorbent generally uses carbonaceous sorbents (following general designation active carbon) such as active carbon, activated charcoal.Because the price of active carbon is high, usually used active carbon is carried out Regeneration Treatment to practice thrift cost, this regeneration is used and is adopted the dry type desulfurizing denitrification apparatus with mobile laminar adsorption tower usually.As shown in Figure 1, move laminar dry type desulfurizing denitrification apparatus and mainly constitute (referring to patent documentation 1) by adsorption tower 1, the regenerator 2 (be also referred to as and break away from tower) that makes regeneration of activated carbon, first conveying mechanism 3, second conveying mechanism 4, vibratory sieve 5.SO in adsorption tower 1 in the absorption waste gas
2And the active carbon that adheres to dust is transferred to regenerator 2 through first conveying mechanism 3.In regenerator 2, active carbon cools off after through the thermal regeneration more than 400 ℃, is transferred in the absorption tower 1 via second conveying mechanism 4 then to recycle.Active carbon when recycling because bump is cut or because wearing and tearing produce fine-powder (below be called activated carbon powder), simultaneously, the fine dust in the waste gas also since the collision control of dust effect between itself and the activated carbon particles be collected.If these activated carbon powders and dust (following activated carbon powder and dust are referred to as dust) are not discharged, will cause the degree of adsorption tower 2 crushings to rise, situation about can't move also may appear.
In the prior art; In the bottom of regenerator 2 vibratory sieve 5 is set; After the active carbon of discharging from regenerator 2 is shaken off dust via vibratory sieve 5, be transferred to absorption tower 1 by second conveying mechanism 4 and recycle, wherein; As shown in Figure 1, the dust that vibratory sieve 5 is shaken off is manually regularly reclaimed with manpower trolley 6 by manual pick.Under the situation that dust concentration is few in the few and waste gas at exhaust gas flow, this manually regularly the recovery can not go wrong usually.Yet, in actual production process, usually following situation can appear:
(1) if exhaust gas flow increases, can only strengthen the model of adsorption tower, correspondingly, the amounts of activated carbon of circulation increases, and the activated carbon powder of generation also increases thereupon;
(2) if exhaust gas flow increases, even the dust concentration in the waste gas is constant, the absolute magnitude of dust also can increase;
(3) even exhaust gas flow is constant, if dust concentration increases, the amount of dust of recovery also can increase.
Based on above-mentioned situation, the amount that reclaims dust increases gradually, and reclaim frequency also increases thereupon, if adopt prior art, this will increase human cost greatly, and, when occurring above-mentioned three kinds of situation simultaneously, also can't tackle even apply the strategy of throwing waves of people into action.
