The utility model relates to a dust collector field, in particular to a pocket type dust collector for semidry process desulfurization.
Background
The semidry desulfurization process is characterized in that desulfurizer particles are used as an absorbent, sulfur-containing flue gas is introduced into an absorption tower, sulfur dioxide in the flue gas reacts with the desulfurizer particles in the absorption tower to remove the sulfur dioxide, then the flue gas carries part of the desulfurizer particles to enter a dust removal unit, and collected dust is returned to the absorption tower for recycling after the dust removal unit removes dust. Because the single tower of the absorption tower has large processing capacity, the diameter of the single tower can exceed 10 meters, and the provided dust removal unit is a large-sized bag type dust remover generally. The bag collector who adopts is generally provided with a plurality of filter bags side by side, and the discharge opening of every filter bag all is provided with solenoid valve and air pump, and the steerable discharge opening of solenoid valve opens and shuts, and the air pump can be with the dust discharge of collecting in every sack to collect a house steward of absorption tower lower extreme, and return the dust that contains the desulfurizer granule to the absorption tower and recycle or discharge the dust. However, each filter bag is provided with an electromagnetic valve and an air pump, so that the equipment is expensive in manufacturing cost, and is easy to break down, so that the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a lower bag collector who is used for semi-dry desulfurization process of simple structure, manufacturing cost and maintenance cost to the technical problem who exists among the prior art.
The utility model provides a technical scheme of above-mentioned problem does: a bag type dust removal device for a semi-dry desulfurization process comprises a plurality of bag type dust removal units which are arranged side by side, wherein each bag type dust removal unit comprises a filter bag, an ash hopper and a discharge pipe which are connected from top to bottom; the bottom of the ash collecting box far away from one end of the main pipe is provided with a blast device, and the bottom of the ash collecting box near one end of the main pipe of the ash accumulating box is connected with a discharge pipe.
The dust is intensively discharged into the dust collecting box by the discharging hoppers and is uniformly treated, the electromagnetic valve and the air pump are not arranged on each discharging pipe, and only the air blowing device is arranged on the dust collecting box, so that the equipment cost and the equipment operation cost are greatly reduced.
Due to the light weight of the dust, air can be mixed under the action of the air blowing device, and suspension occurs. Under the flow guide effect of the top of the dust collection box, the suspended dust can move to one side of the main pipe, so that the energy consumption of the dust in the motion process is low, and the operation cost of the equipment is reduced.
In addition, because the desulfurizer generally adopts limestone with smaller particle size, and the final product generated by the limestone and sulfur dioxide is calcium sulfate with larger particle size, the desulfurizer and calcium sulfate dust are easier to suspend in the ash collection box, so that the desulfurizer can more easily enter the main pipe, and the recovery of the desulfurizer is facilitated.
Further, the air blowing device is an air pump.
The air pump mechanism is simple, the cost is low, and the equipment cost can be further reduced.
Further, the discharge pipe is connected with a dust suction device.
When dust is more in the dust collecting box, the dust can be rapidly treated by the dust suction device, and the working efficiency is improved.
Further, the dust suction device is a dust pump.
The dust pump mechanism is simple, the cost is low, and the equipment cost can be further reduced.
Furthermore, valves are arranged on the main pipe and the discharge pipe.
After the valve is arranged, the dust can be controlled to flow to the dust collecting box, and when more dust needs to be discharged from the dust collecting box, the valve on the main pipe can be closed.
Further, the discharge pipe is connected with the dust collecting box in a sealing mode.
The sealed connection may reduce dust escape.
Furthermore, the lengths of the discharge pipes extending into the dust collecting box are the same and are 1/20-1/10 of the minimum height of the box body.
The length that a plurality of discharge tubes deepened ash-collecting box is shorter, has reduced the hindrance of discharge tube to the dust, makes the dust be blown to house steward one side more easily.
Further, the ash collecting box top and the horizontal plane included angle are 20 ~ 45.
The included angle between the top of the ash collecting box and the horizontal plane can play a better role in guiding flow within the range.
