Abstract

The invention relates to a dust collection technique, can be used in chemical and other areas of industry and allows to increase the degree of regeneration of the sleeves. By intensifying the effect of dust accumulated on the layer in the bag filter, the tops of the upper cones of the regenerating elements 11 are connected to thread 9 by means of hinges 10 and On the side surface of the lower truncated cones of the regenerating elements 11 are fixed inclined elastic plates 12. 2 Il.

The invention relates to cleaner equipment, namely to apparatus. for the dry cleaning of gases from dust particles by the filtering method, can be used in the chemical and other sectors of the industry and is an improvement of the invention in the field of auto power, 1230643,

The purpose of the invention is to increase the degree of regeneration of the sleeves by intensifying the effect on the layer of dust deposited on the filter sleeves and thereby increasing productivity and reducing energy consumption during cleaning of leaked gases.

Fig 1 is a schematic of a bag filter; in fig „2 - raeree aa on figo1.

The filter is on (it includes the body 1 with the cover 2, the gas inlet nozzle 3 and the clean gas outlet nozzle 4. Inside the housing 1 there are hose grids 5 and 6, upper and lower, respectively, on which the filter sleeves 7 are fixed. -block-8 reciprocating during the operation.The block diameter is equal to the sum of the diameter of the sleeve and the distance between the sleeves.Through block 8, a flexible thread 9 is thrown at the ends of which are fixed to the vertices by means of hinges 10 regenerating elements 11, wavelengths in the form. Vuh cones Lower cone regeneriruyu-; conducting element 11 is truncated, and at its lateral surface sloping flexible plasti secured

12o. A hopper 13 is attached to the lower part of the housing 1 for collecting pypi. The dust settled in it is removed from the filter by the feeder 14.

The bag filter works as follows.

The dust-laden gas through pipe 3 enters the upper part of body 1 and passes into the sleeves 7, through which it is filtered and taken out of the pipe, the passage of the pipe 4. Writing settles down the inner surface of the sleeves 7, thereby creating a certain resistance of the filter septum. This resistance causes the gas flow to pass with increasing velocity in the gap between the regenerating element 11 and the sleeve 7. The passage in the gap, the gas flow

imposes pressure on the inclined elastic plates 12 and thus the o6i3a30M causes the regenerating element 11 to rotate around its axis at the hinge 10 ". Due to the high velocity of the gas flow in the gap and as a result of the mechanical action of the elastic plates 12 on the layer deposited on the sleeve 7, the intensive removal from the surface of the sleeve 7. The removed dust is then deposited in the hopper 13 towards the feeder 14 from it. The combined mechanical and aerodynamic effect on the layer of the seals deposited on the sleeve 7 is more cient for sravnensho one aerodynamic effect, which leads to degrees povshe- NIJ sleeves 7 regeneration.

Since the block 8 performs a return-and-forward movement, the regenerating elements 11 are constantly moving at low speed along the entire length of the sleeves 7 in opposite directions of the ho. As a result, the entire surface of the sleeves 7 regenerates. The speed in the gap between the regenerating element 11 and the sleeve 7, and therefore, the degree of regeneration is maintained constant regardless of where the sleeve 11 is located, since the resistance of these elements is the same. If one regenerating element is in the upper part of the sleeve, and the other is in the lower part (Fig 1), then there is an overflow of gas that has passed into the gap in the right sleeve to the left sleeve. Gas flow will not be observed only in the case when two regenerating elements 11 are in the middle part of the sleeve 7. Thus, the system is balanced and is in dynamic equilibrium. The gas that has passed into the gap between the element 11 and the sleeve 7 is either filtered in this sleeve or flows into the neighboring one.

As a result of the combined mechanical and aerodynamic effects on the layer of fluff deposited on the filter sleeves, the degree of regeneration of the sleeves increases. This increase in the degree of regeneration of the sleeves becomes pronounced when trapping fine drums.

As the degree of regeneration of the sleeves increases, the dust layer on them is reduced.

It provides less resistance to the gas flow to be cleaned, as a result of which the hydraulic resistance of the filter is reduced. At the same time, the filtration rate increases. A decrease in the hydraulic resistance of the filter leads to a decrease in energy consumption, and an increase in the filtration rate increases the productivity.
