Description
Technical Field
The invention belongs to the technical field of dust collectors, and particularly relates to a method for replacing a filter bag by an electric modified bag dust collector.
Background
The electrostatic precipitator that thermal power factory, iron and steel works used is its overall dimension very huge, along with the environmental protection requirement improves, electrostatic precipitator's dust emission concentration has not reached standard, from this, most electrostatic precipitator need change into filter bag dust collector, and filter bag dust collector still has following advantage compared with electrostatic precipitator: 1. the running resistance is low, and the air inlet mode of the electric-change bag type dust collector is straight-through; 2. the internal space is fully utilized, the electric modified bag type dust collector adopts a long bag arrangement mode, the length of a filter bag is generally 6-8 m, and compared with the original dust collector, the electric modified bag type dust collector can treat larger air quantity in the same dust collection space; 3. the dust remover is changed on the basis of the original dust remover, so that the occupied area of equipment is not increased, and the construction period is short.
The technical scheme of the current electric changing bag mainly comprises the following steps as shown in figure 1: the device comprises a device shell 01, an inlet 02 for introducing dust-containing gas, an air outlet channel 03 above the device shell 01, clean rooms 04 on two sides of the air outlet channel 03, ash hoppers 05 arranged at the lower parts of the corresponding clean rooms, wherein a closable overhaul port is arranged on the upper surface of each clean room 04, a filter unit is fixedly arranged at the lower part of each clean room, each filter unit is formed by combining a flower plate 210 fixedly arranged on the bottom surface of the clean room and a plurality of densely distributed and vertical filter bag assemblies which are regularly arranged and sleeved on the flower plate 210, during operation, the dust-containing gas is introduced into the filter units from the inlet 02, large-particle dust directly falls into the ash hoppers 05, tiny dust is adhered to the surfaces of the filter bags after being filtered by the filter bag assemblies, and then the filter bags are reversely blown by arranging pulse ash cleaning assemblies 06, so that the filter bags vibrate and deform, and when the adhered dust is shaken off, the filter bags fall into the ash hoppers 05 for post treatment, and the filter bag filtering capacity is restored to the original. The pulse ash cleaning component 06 is fixedly arranged in each clean room 04, the pulse ash cleaning component 06 comprises an exhaust pipe fixedly arranged in the clean room 04 and a steam drum externally connected with the exhaust pipe, the exhaust pipe corresponds to the filter bag assembly arranged at the lower part in a regular mode, and nozzles which correspond to the openings of each filter bag assembly one by one are arranged in the exhaust pipe and can be used for blowing air flow into the filter bag assembly at regular or irregular time to clean ash. The length of the filter bag assembly is 6-8 meters, so that when the electric change bag is installed and the filter bag is maintained and replaced after later use, a large amount of operators are needed to input the dense filter bag assembly, and because the operators are in a high position, dust is large when the filter bag is replaced due to a narrow moving range and a lot of dust adheres to the filter bag, the weight is heavy, and a calandria needs to be removed during replacement.
The filter bag installation or the replacement of a large number of filter bags with the factors needs to be performed fully manually, the labor intensity is high, and particularly when the new cloth bags are maintained, the pulse ash removal component 06 is required to be detached firstly, so that the procedure is complicated; on the other hand, in view of the length of the filter bag assembly and the characteristic that the rigid bag cage matching the filter bag cannot be bent, it is difficult to arrange the filter bag assembly directly under the air outlet channel 03, because the operator does not have a working space in which the filter bag assembly can be vertically placed, as can also be seen from the figure, and thus the technical scheme has the defect of insufficient utilization of the internal space of the device housing 01.
