Description

dust separator for separating solid constituents from gases or vapors.

To the patent of the in-ing company "Anonymous manufacturing plant for

machines and apparatus (Naamfooze Vennootschap Nachinerieen ch Apparaten

Fabrieken), in Utrecht, Holland, following the 20th of May 1927

(for century. certificate. № 16882,

The real inventor of the Institute-In, Teuke (Walter Teuke).

On the issuance of a patent published npar 1932. The patent is valid for 15 years from January 31, 1931.

The present invention relates to a dust separator serving to release solid components from gases or vapors and consisting of short-circuits of fixed grooves or similar kilometers of bodies, past which the gas-vapor mixture advances.

In the drawing, fkg. 1 shows a diagram of the arrangement; grooves in a dust separator; FIG. 2 - horizontal section of the dust separator; FIG. 3rd longitudinal vertical section; FIG. 4th transverse vertical section.

The author found that with such grooves in the dust separator, the walls of which are flat and the like faces facing the gas flow, the angle n ((png. 1) formed by the walls of the grooves plays an important role. To improve the separation of solid particles from the gas-steam mixture, (Fig. 1) in the proposed dust separator is made equal to 50-70 °. The width & (Fig. 1) of the grooves' walls and the gap with (Fig. 1) between the

grooves in the transverse direction to the main flow path. The smaller the groove wall width and the gap between them, the more perfect the gas flow is divided into parts and the easier the dust particles fall from the middle of the gas streams between the grooves to places of lower velocity behind the grooves. Therefore, the width of 1 walls of the grooves make in the proposed dust separator less Yum. and clearance between grooves with less than 5 mm.

However, the lumen d (Fig. 1) between the grooves in the direction of gas flow and the general location of the grooves in this direction is also of greater importance. Most of the dust is separated from the grooves encountered by the gas stream at the beginning. In the following grooves, the proportion of the weight of the separated dust and the size of its grains rapidly fall. Therefore, it is not advisable to arrange a larger number of grooves one after the other, but, on the contrary, it turned out to be useful to interrupt the longitudinal grooves formed by the grooves in the direction of gas flow.

) 1 d i.e. arrange along the length of dust separation one or several zones not occupied by grooves (Fig. 1). Therefore, in the proposed dust separator, a number of grooves in the direction of the gas flow is combined in F () uppa, each not more than 4 gutters, with free zones between the groups, the length of which is not less than 2 (1.V

The fixing of the grooves in the cleaner housing is carried out in a manner known per se. The grooves are inserted into round or triangular holes in the supporting bottoms f and fi and the protruding ends of the grooves flatten. The grooves can be located vertically or obliquely. Since gas condensates prevent dust from sliding down the grooves, the gas must not cool down the condensation point before or when passing by the grooves; likewise, since the outer walls of the cleaner's casing form a cooling surface for the gas after the dust has been separated, the cleaner's casing is attached quadrilateral in plan and an element formed by groups of one row connected next to each other (from d to / ii), arranged and paired A common chamber for the gas inlet of each pair element (for example, d and gi) is located in the middle (for example, chamber of group d and i) and the gas is added to the chamber; frontal side of the casing cleaner. The gas outlet chambers I, li, In (Figs. 3 and 4) are located between the paired elements or on the outer walls of the casing and from them gas is removed in the same way as the gas supply through the collecting chamber (Fig. 4), on the other side of the housing. As a result, only the gas supply chamber is needed for isolation. and lid n casing dust separator. Lower support

The bottom of the DG is well protected from heat transfer by the underlying dust chambers. Thus, the remaining three outer edges of the separator can be used to cool the gas. The lower supporting bottom f under chambers d, gas inlet g and ij and chambers for outlet I, li, 1- is supplied with holes p and (Fig. 2 and 3) for dust removal into dust chambers}. The latter is divided by walls q parallel to the transverse A series of grooves into separate chambers T and / D To extract dust from the dust chamber: the latter is equipped with a door S (Fig. 4).

The proposed dust separator is used in conjunction with filtering apparatus, which serves to separate more fine dust, in order to trap larger dust particles, clog up the filters.

 of the patent.

1. A dust separator for separating solid constituents with stationary grooves or similar telpip and passing past them from gases or vapors; gas mixture of gas vapor, characterized in that the walls of the grooves make an angle of 50 ° to 70 ° between them while uii niiii & the walls b and the gap between the grooves in the transverse direction are 2: 1.

2. The form of execution of the dust separator, referred to in paragraph 1, characterized in that the transverse rows of grooves following each other in the direction of gas flow are grouped into groups, each not more than three rows, leaving the free zone between the groups, The free length of which, in the directional flow of gases, is at least twice as large as the lumens // J of a number of grooves in groups.
