Abstract

A device for collecting fine particles, consisting of a plurality of separators, which are partitions with alternating longitudinal slots, acting on the principle of impact, having a length, width and depth, located in at least two rows along the path of the dusty gas with gaps between the separators. According to the present utility model, partitions with alternating longitudinal slots required for perpendicular installation of plates in them have a perpendicular bar from their upper and lower ends, which defines the distance between adjacent partitions. In addition, each subsequent partition is installed parallel to the previous one and with a 180 ° rotation in order to organize a zigzag channel for the passage of dusty gas. The technical result is an increase in the overall efficiency of capturing fine particles due to a more rigid connection of separators, which exclude large deflections, an increase in the rigidity of the structure, the possibility manufacturing a structure without special equipment.

Description

The utility model relates to the technique of gas cleaning from fine dust and can be used in various industries: chemical, metallurgical, food, energy and other areas of industrial and economic activities.

An analogue is a device for collecting and removing particles entrained in the flue gas in the furnace, containing a plurality of separators having length, width and depth, located along the gas flow in the furnace, located in at least two rows along the path of the flue gas with gaps between the separators allowing a certain amount of particles in the flue gas to avoid capturing, and the separators in each subsequent row are located between the separators in each previous row [Patent RU 2106577, F23J 15/00, B01D 45/00, B01D 45/08 from 10.03.1998]. Separators are concave reflective elements of U-shape, E-shape or W-shape, acting on the principle of impact. In addition, the separators are located in or after the furnace and at least one subsequent row of separators is located from the previous one at a distance equal to the depth of the separator.

The disadvantage of the analogue is a significant difference in the fields of centrifugal forces that arise in the area behind the separators and inside them, which leads to a decrease in the overall efficiency of trapping solid dispersed particles.

The prototype is a device for fine dust and gas cleaning, containing a plurality of separators, which are concave reflective elements acting on the principle of collision, having a length, width and depth, located in at least two rows along the path of dusty gas with gaps between separators, with separators in each subsequent a row are located between the separators in each previous row [Patent RU 171615, B01D 45/06, B01D 45/08 from 07.06.2017]. The separators are I-beams with concavity on both sides, with the gap between them in each row being equal to the length of the I-beam.

The disadvantage of the prototype is the inconvenience of assembling the structure, the need for special equipment for the manufacture of I-beams, possible deformation (deflection) of I-beams, which leads to a violation of the regularity of the dusty gas flow structure.

The task of the utility model is to develop a device for capturing fine particles, in which the disadvantages of the analogue and the prototype are eliminated.

The technical result is to increase the overall efficiency of capturing fine particles, achieved due to the ordered structure of the gas flow due to the more rigid connection of the separators, which exclude large deflections, an increase in the rigidity of the structure, the possibility of manufacturing the structure without special equipment.

The technical result is achieved in that a device for capturing fine particles, consisting of separators, which are partitions with alternating longitudinal slots, acting on the principle of collision, having length, width and depth, located in several rows on the path of dusty gas with gaps between separators. According to the present utility model, partitions with alternating longitudinal slots required for perpendicular installation of plates in them have a perpendicular bar from their upper and lower ends, which defines the distance between adjacent partitions. In addition, each subsequent partition is installed parallel to the previous one and with a 180 ° rotation in order to organize a zigzag channel for the passage of dusty gas. In this case, the plates have slots along their entire height and width, and two transverse bridges, equidistant from each other in height, ensuring the rigidity of the structure of connected plates and partitions, which is fixed by studs with nuts at the ends passing through the body, cover and plates, thus most excluding the possibility of displacement of the plates, large deflections, increasing the rigidity of the structure.

The essence of the utility model is illustrated by drawings:

in fig. 1 shows a device for capturing fine particles;

in fig. 2 is an assembly diagram of the device.

The numbers in the drawing indicate:

1 - case,

2 - plates,

3 - partitions with slots,

4 - cover,

5 - hairpins,

6 - nuts.

The device for capturing fine particles contains a housing 1 with plates 2 installed in it and a plurality of separators, which are partitions 3 with alternating longitudinal slots designed for installing plates 2, a cover 4, pins 5, nuts 6. From the end sides of the housing 1 and cover 4, holes are made for the passage of pins 5. Pins 5 are used to connect the body 1, plates 2, partitions 3 and cover 4 with each other, while the pins 5 pass through the slots in the plates 2. Nuts 6 are screwed onto the ends of the studs 5 as a fixing element.

The proposed device for capturing fine particles operates as follows.

The dusty gas stream enters the proposed device for capturing fine particles from the side not enclosed in the housing 1, through the slots in the partitions 3 along a Z-shaped trajectory and exits from the opposite side. When the direction of the gas flow is changed, a centrifugal force is generated, which contributes to the uniform deposition of dust particles on the entire surface of the plates 2 and partitions 3. The presence of several rows of partitions 3 leads to an increase in the efficiency of capturing fine particles due to a more structured gas flow. When a significant layer of contamination is reached on the surface of plates 2 and partitions 3, due to which the efficiency of dust collection decreases and the hydraulic resistance increases, they are cleaned mechanically.

In the proposed device for capturing fine particles, a more regular organization of the structure of the dusty gas flow is provided, since the plates and baffles are installed perpendicular to each other. To exclude vibrations of the assembled block from plates and partitions, to exclude deflection of the structure, as well as to ensure the rigidity of the structure, it is fixed with studs passing through the body, cover and plates, thereby eliminating the possibility of displacement of the plates. This means that, all other things being equal, the efficiency of the deposition of fine particles will be comparable to that of the prototype.

Thus, the rigid connection of the combined partitions and plates in the proposed device for capturing fine particles leads to an increase in the overall efficiency of capturing fine particles, an increase in the rigidity of the structure, the simplicity of the elements makes it possible to manufacture the structure without special equipment.
