Description

(54) BATTERY CYCLONE

I

The invention relates to gas and bullet purification technology and can be applied in the chemical, energy and other industries.

A multiscale dust collecting installation is known, consisting of series-connected dust collectors with systems, suction fll.

The battery cycle contains coaxial, clean and gas-filled chambers separated by a partition, a central dust extraction pipe installed vertically along the cyclone axis and cyclone elements located around the latter radially blued, the axes of which in each tusk are shifted in plan relative to the respective axes of the previous tusk; the elements are installed in a clean gas chamber located inside a dusty gas chamber, equipped with a tangential inlet.

The design of this cyclone has two successively compacted steps: a single cyclone and a battery cyclone.

, To increase the efficiency of the second stage, use a suction system from the second stage bunker, containing a dust collector, and a suction fan,

This device is reliable in working with explosive dust due to an imperfect suction system.

The closest in technical essence and achievable result is LYET with a battery cyclone, comprising a housing, yctaHOBJjeHHbie vertically inside it is a first and second stage cyclone elements with output chambers of collected dust and purified gas and dust trays 2.1.

The disadvantage of the known cycle is its low explosion safety.

The object of the invention is to increase the explosion safety of a cyclone by ensuring the convergence of dust with the internal surfaces of b.

Claims (2)

The goal is achieved by coaxially the output chamber of the collected dust of the first stage, the output chamber of the cleaned gas of the second stage, inside of which the axis of the dust extraction of the first stage is located along the axis. ;.: It is also advisable to install the second-stage cyclone elements by ring rows around the clean gas outlet chamber. FIG. 1 shows the proposed cyclone; in fig. 2 shows section A-A in FIG. 1. The battery cyclone contains annular rows of cyclonic elements 1 of the first stage of dust: infusions installed to an axially cylindrical case 2. Inlet 3 of the dusty stream is central, and the output of the purified gas of the organ & n into the annular channel 4 located along the periphery of the case 3 and passes into the receiving chamber 5 of the annular rows of cyclone elements 6 of the second stage of dust collection located in the housing 2 under the elements of the first stage coaxially to the bunker 7 of the first stage so that the dust suppressor 8 from the first stage put on the center of the group of the second cyclone stage and in the output would rub 9 .. second stage cyclone hopper 10 zlem ontov second stage is used battery cyclone bottom. . ..---"one.---. The battery cyclone operates as follows ..., -. The dusty stream through the inlet 3 enters the cyclonic elements 1 of the first dust removal stage, where it is freed from dust particles and the cleaned enters the B ring; the wok canal 4, where through the receiving chamber 5 enters the cyclone elements 6 of the second dust removal stage, dehydrating them thoroughly and exits through the exhaust pipe 9. The dust collected in the cyclone elements 1 of the first dust removal stage is poured into the bunker 7 and along the path 8 of the dust release from the DRIVE of the battery cyclone. Py, l, caught in the cyclone 6 elements of the second stage refers to the hopper 10. The use of the proposed makes it possible to improve konbtruyshi of AByxcTjneMaToro batareShgrgo CEC jiOHa dust convergence resulting vypol} tim its partitions, tube sheets, lids and bottoms in the form of coaxial cones, and also the central location of the dusting of the first stage. This increases the blast-resistant design and reliability. Two light location of the first and second stages makes it possible to reduce construction sites. This makes it possible to install a pre-construction design, for example, above the industrial dust bin as the second and third mechanical dedusting stage. open dust system. Claim 1. Battery cyclone, comprising a housing, vertically mounted inside it cyclone elements of the first and second stages with outgoing chambers of dust and cleaned gas and dust jets, characterized in that, in order to improve the explosion safety of the cyclone by ensuring convergence of dust from its alternating surfaces , the output chamber of the cleaned gas of the second stage is installed coaxially with the output chamber of the collected dust of the first stage, inside which the first stage dust extraction channel is located along the axis . 2, the cyclone according to claim 1, in which the cyclone elements of the second stage are mounted in annular rows around the exit chamber of the purified gas.
