Abstract
The utility model discloses an absorption tower bottom accumulated dust blowback blockage-cleaning device which is characterized by comprising a dust-conveying device arranged in the bottom of an absorption tower. The dust-conveying device comprises multiple rows of blowback nozzles which are connected with a compressed air inlet. The absorption tower bottom accumulated dust blowback blockage-cleaning device effectively solves the problem of accumulated dust in the tower bottom and has the advantages of being reasonable in design, convenient to maintain, low in equipment cost, capable of improving use ratio of absorbents, reducing work amount of tower bottom dust-cleaning and improving operation environment of between work regions and in a factory.
Description
Technical field
The utility model relates to a kind of absorption Tata prodelta clay ash blowback sweeping device, is applied to the circulating fluid bed semi-drying method desulfuration field.
Background technology
Recirculating fluidized bed flue gas semi-dry desulphurization technology is a kind of new desulfur technology of the 80's of 20th century later development.See that from practical operation situation this technology has been tending towards ripe and the irreplaceable premium properties of other technology is arranged, the market demand progressively enlarges.
The capital equipment desulfurizing tower of circulating fluid bed semi-drying method desulfurization is made up of entrance, venturi section, direct tube section, outlet section four parts.Flue gas is got in the tower by entrance, through the venturi section of tower bottom, mixes with absorbent that adds from the venturi diffuser and technology atomizing water, continues reaction through direct tube section then, and outlet section flows out from tower top at last.Flue gas gets into sack cleaner subsequently, and the desulphurization ash that separates through deduster continues to participate in reaction in air flume is sent tower back to.
In the semi-dry process flue gas desulphurization process, the ash that falls at the bottom of the absorption Tata is very general at present, and the phenomenon that especially bulky grain drops at the bottom of tower in the absorption tower is more serious, and normal processing is at the bottom of absorbing Tata, the taper ash bucket to be set, and regularly clears.Handle wasting raw material like this, increase operating cost, and the deashing workload is big, human input is many.Therefore, should provide a kind of new technical scheme to address the above problem.
The utility model content
The purpose of the utility model is: to above-mentioned deficiency, provide a kind of easy to maintenance, equipment cost is low, can improve the absorbent utilization rate, the absorption Tata prodelta clay ash blowback block clearing device of deashing workload at the bottom of the minimizing tower.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of absorption Tata prodelta clay ash blowback block clearing device comprises being arranged on the ash conveying device that absorbs at the bottom of the Tata that said ash conveying device comprises many row's blowback nozzles, and said blowback nozzle is connected with compressed air inlet.
Said ash conveying device comprises 3 row's blowback nozzles.
Every row's blowback nozzle comprises 20 blowback nozzles.
A kind of absorption Tata of the utility model prodelta clay ash blowback block clearing device; At the bottom of existing absorption Tata, ash conveying device is set, said ash conveying device comprises many row's blowback nozzles, and said blowback nozzle is connected with compressed air inlet; The compressed air of 0.6-0.8MPa is continued to be blown at the bottom of tower; One can effectively stop particles settling, and the dust stratification that two abilities will be deposited at the bottom of the tower blows afloat, and makes it to bring the tower body middle and upper part into flue gas and participates in circular response again.
The beneficial effect of the utility model is: the utility model has solved tower prodelta clay ash problem effectively, and reasonable in design, easy to maintenance, equipment cost is low, can improve the absorbent utilization rate, and deashing workload at the bottom of the minimizing tower is improved between the operation area and plant area's running environment.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Wherein: 1, absorption tower, 2, ash conveying device, 3, the blowback nozzle, 4, compressed air inlet.
The specific embodiment
As shown in Figure 1, a kind of absorption Tata of the utility model prodelta clay ash blowback block clearing device comprises the ash conveying device 2 that is arranged at the bottom of 1 tower of absorption tower, and ash conveying device 2 comprises 3 row's blowback nozzles 3, and every row's blowback nozzle comprises 20 blowback nozzles.Blowback nozzle 3 is connected with compressed air inlet 4.A kind of absorption Tata of the utility model prodelta clay ash blowback block clearing device; At the bottom of 1 tower of existing absorption tower, ash conveying device 2 is set, ash conveying device 2 comprises many row's blowback nozzles 3, and blowback nozzle 3 is connected with compressed air inlet 4; The compressed air of 0.6-0.8MPa is continued to be blown at the bottom of tower; One can effectively stop particles settling, and the dust stratification that two abilities will be deposited at the bottom of the tower blows afloat, and makes it to bring the tower body middle and upper part into flue gas and participates in circular response again.
