Abstract

The invention relates to a process for the purification of gases from sticking dusts and allows for an increase in the efficiency of dust cleaning. Dust gas enters the apparatus through the tangential nozzle 2, acquiring rotational motion. Under the action of centrifugal force, dust particles reach the near-wall zone and, streamlined chain link arms, are deposited on their surface due to the inertial effect. The purified gas exits through the nozzle 4. Upon reaching the limiting layer of dust on the chains, regeneration is carried out, together with the rotational-oscillatory movement through the movable ring 5 connected to the drive of the regenerating device. Due to the presence of bandages 7, the aerodynamic stability of chain beams is increased. 3 il. S (L cond with JV CO

Description

The invention relates to technological processes for the purification of gases from sticking dusts, such as chalk, lime, soot, etc., and can be used in the enterprises of the building materials industry, in the metallurgical, chemical industry, energy, and other sectors of the national economy.

The purpose of the invention is to increase the efficiency of dust cleaning.

FIG. 1 shows a dust collector, an incision; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The dust collector includes a housing 1 to which a tangential inlet is attached.

from a material with a specific mass of 7.8–8.1 g / cm, chain links of 30–40 mm in length from a rod with a diameter of 3-4 mm have the highest efficiency. The distance between the tires is (8-12) G, where is the length of the link.

Upon reaching the limiting layer of dust on the chain arms and the walls of the housing 1, the dust collector is stopped and regeneration is performed by turning on the actuator 9 of the regenerating device, which informs the reciprocating and rotating movement of the ring 5 with the chain arms suspended on it 6. The reciprocating-rotating movement of the ring 5 changes to complex (rotator 20

pipe 2 and cover 3 with an exhaust-15-oscillatory, etc.) movement is suspended by 4, under which movably mounted chain arms 6, which, colliding with each other and against the walls of the housing 1, provide Intensive discharge of collected dust into the bunker. The proposed device allows to increase the efficiency of the trap by increasing the efficiency and degree of gas purification, increase the inter-regeneration period, reduce the hydraulic resistance to the upward vortex flow due to the creation of a free space of 25 ti , acquires the rotational engine of various components and equipment parts),

living Under the action of centrifugal force, gas purification in the production of dispersion particles of the drink reaches the near-wall common chalk in cyclones with metal-porous material.

The area and, around the chain links are 6, the lining is 80-85%. Calculated

due to the inertial effect and high efficiency of purification of the same gases, the uloadhesive properties are deposited on their 30 viter of the proposed design; ring 5 is formed with chain bearers 6 suspended from it, bandages 7 fixed between each other, dust bin 8 installed outside the case, drive 9 regenerating devices, such as a cable system.

Dust collector works as follows.

Dust-laden gas entering the apparatus is 93-94% pure.

the surface and the inner surface of the housing 1. Part of the dust is separated from the vortex flow directly into the hopper 8, the purified gas exits through the exhaust manifold 4.

The efficiency of trapping sticky dust in the dust collector is higher, the smaller the chain links and the diameter of the rod from which they are made, as this increases the Stokes criterion.
