Description
Technical Field
The utility model relates to a flue gas dust collecting equipment technical field especially relates to a bag dust collector.
Background
Flue gas generated by industry, such as waste gas generated by brick and tile plants, cement plants and the like, contains a large amount of harmful substances such as sulfide, dust and the like, and can be discharged into the air after being treated to reach the national standard. The equipment for separating dust from flue gas is called dust remover or dust removing equipment. The existing dust removing equipment mainly adopts electrostatic dust removal, the investment of the electrostatic dust removal is large, the energy consumption is large, the operation cost is high, the structure is complex, the occupied area is large, and the national response to energy conservation and emission reduction can not be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problems, providing a bag dust collector, very big reduction dust removal cost and energy resource consumption, simple structure, transformation and running cost are low. Occupation space is less, can directly combine with current desulfurizing tower to remove dust, and the stability that the physics was removed dust is better, need not use high voltage electric power, and is safer.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a filter bag dust collector comprises a plurality of water tanks fixed on a water tank supporting pore plate, wherein filter bags are suspended in the water tanks, and the upper parts of the filter bags are fixed on the filter bag supporting pore plate;
the filter hole is arranged on the filter bag supporting pore plate and is in contact with the filter bag, and the positions which are not in contact with the filter bag are all sealing plates;
and the upper part of the filter bag is provided with a tube filter spraying layer.
The water tank supporting pore plate is provided with filtering holes except the positions contacted with the water tank.
Still be equipped with the defroster on the tub strains the spraying layer, be equipped with on the defroster and spray the layer.
The demister is also provided with a spraying layer.
The upper part of the spraying layer is closed and then connected with the chimney.
The utility model has the advantages that:
the utility model discloses very big reduction dust removal cost and energy resource consumption, simple structure, transformation and running cost are low.
The occupied space is less.
The physical dust removal stability is better, high-voltage power does not need to be used, and the device is safer.
The dust removal effect can be ensured, and the national policy of energy conservation and emission reduction is completely met.
Drawings
Fig. 1 is a schematic structural view of the present invention;
the filter bag type water purifier comprises a spray layer 1, a demister 2, a tube filter spray layer 3, a filter bag support pore plate 4, a filter bag 5, a water tank 6 and a water tank support pore plate 7.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1, a bag-type dust collector comprises a plurality of water tanks 6 fixed on a water tank support orifice plate 7, wherein filter bags 5 are suspended in the water tanks 6, and the upper parts of the filter bags 5 are fixed on a filter bag support orifice plate 4;
the filter bag supporting pore plate 4 is provided with filter holes at the positions contacted with the filter bags 5, and sealing plates at the positions not contacted with the filter bags 5; the upper part of the filter bag 5 is provided with a tube filter spraying layer 3.
The water tank supporting pore plate is provided with filtering holes except the positions contacted with the water tank.
Still be equipped with defroster 2 on the tube filtering sprays layer 3, be equipped with on the defroster 2 and spray layer 1.
The upper part of the spraying layer 1 is closed and then connected with a chimney.
During working dust removal, the flue gas is subjected to preliminary dust removal through a tube bundle dust removal system;
the flue gas after primary dust removal by the tube bundle dust removal system is subjected to dust removal again by the filter bag dust removal system;
the pipe filter spraying layer washes the flue gas particles attached to the filter bag to a water tank, so that the filter bag is prevented from being blocked.
Still be equipped with the defroster on the tub filter sprays the layer, be equipped with on the defroster and spray the layer, the flue gas is discharged after the defroster after filter bag dust pelletizing system removes dust once more at last.
Water enters the water tank through the filtering spraying layer, a water seal is formed when the lower part of the filter bag is immersed in water, the upper part of the filter bag is sealed by the filter bag supporting pore plate, smoke can only be upwards discharged through the filter bag, dust in the smoke is filtered by the filter screen of the filter bag, and then the smoke is washed by the filtering spraying layer of the upper part.
A tube bundle spraying layer is arranged above the tube bundle in the tube bundle dust removal system and used for washing the tube bundle.
The working principle is as follows: the dust-laden flue gas is dedusted by the filter bag, and flue gas particles attached to the filter bag are washed to the water tank by the pipe filter spraying layer of the filter bag, so that the filter bag is prevented from being blocked, and finally the flue gas enters the chimney to be discharged outside after passing through the demister. Water enters the water tank through the filter bag, a water seal is formed by immersing the lower part of the filter bag into water, the upper part of the filter bag is sealed by the filter bag supporting pore plate, smoke can only be upwards discharged through the filter bag, dust in the smoke is filtered by the filter screen of the filter bag, and then the upper pipe filter sprays the washing layer.
Compared with a traditional electrostatic dust collector, the dust collector greatly reduces dust removal cost and energy consumption, is simple in structure, small in occupied space, good in physical dust removal stability, free of high-voltage power and safer. And the dust removal effect can be ensured. Completely accords with the national policy of energy conservation and emission reduction.
Although the present invention has been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
