Description

Изобретение относитс к оборудованию строительного производства, а именно к аппаратам дл обработки асбестной суспензии.The invention relates to equipment for the construction industry, namely, apparatus for the treatment of asbestos suspension.

По основному авт.св. Vf 552379 известен аппарат дл обработки суспензий , состо щий из конфузора, цилиндрического проточного участка, в котором установлен один каскад сопел, состо щий из двух р дов, диффузора и коллектора с подвод щим патрубком l.According to the main auth. Vf 552379 a suspension processing apparatus is known, consisting of a confuser, a cylindrical flow path in which one nozzle stage is installed, consisting of two rows, a diffuser and a collector with a supply pipe l.

Недостаток работы такого аппарата состоит в том, что процесс обработки в нем происходит недостаточно интенсивно, а таюхе в значительных удельных энергозатратах.The drawback of the operation of such a device is that the processing process in it is not intensive enough, and tayuhe in significant specific energy consumption.

Цель изобретени - интенсификаци обработки суспензии за счет создани резонансных пульсаций жидкости и снижение удельных энергетических затрат.The purpose of the invention is to intensify the processing of the suspension by creating resonant pulsations of the liquid and reducing the specific energy costs.

Цель достигаетс тем, что в аппарате дл обработки суспензии коллектор дл подачи жидкости снабжен пульсатором , установленным на его подвод щем патрубке.The goal is achieved by the fact that, in the suspension treatment apparatus, the fluid supply manifold is equipped with a pulsator mounted on its supply nozzle.

На фиг. 1 схематически изображен аппарат с коллектором, расположенным внутри проточного участка, общий вид, на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows schematically an apparatus with a collector located inside the flow path, a general view, in FIG. 2 is a section A-A in FIG. one.

Аппарат содержит конфузор 1, цилиндрический проточный участок 2, The apparatus contains confuser 1, a cylindrical flow area 2,

10 в котором установлен, по крайней мере, один каскад сопел 3 диффузор 4, коллектор 5 с подвод щим патрубком 6 и пульсирующим устройством 7.10 in which at least one cascade of nozzles 3, diffuser 4, collector 5 with inlet pipe 6 and pulsating device 7 is installed.

Аппарат дл обработки суспензии Slurry Handler

15 работает следующим образом.15 works as follows.

Поток суспензии, благодар поджатию в конфузоре 1, который увеличивает скорость транспортировки массы, поступает в проточный участок 2, The flow of the suspension, due to preload in the confuser 1, which increases the speed of mass transportation, enters the flow section 2,

Claims

20 where it flows into oncoming jets of liquid, which flows through the inlet pipe 6 and the pulsating device 7 through the manifold 5 and is ejected from the nozzle cascade 3 - The pulsary device 7 provides pulsation of the jets that are ejected from the nozzle cascade 3 Cavities filled with bubbles form at the entire cross section of the flow area, and when closed, zones of collapsing microbubbles are generated that generate intense high-speed pulses. les-pressure and high-speed Cumulative microjet. These pressure fields and micro jets affect the slurry. In the diffuser (the flow rate is reduced to the original mass transport rate., 1p cavities filled with cavitation bubbles in normal operation, without a pulsator, oscillations with a natural frequency are characteristic. If the frequency of the liquid pulsations using the pulsating device 7 coincides with the natural frequency of oscillations of the cavity , the specific energy consumption for the creation of cavities decreases by a factor of 2–5 with an increase in the volume of the cavity with the same expenditure of energy, and simultaneously with an increase in the volume of the cavity with the same costs of energy at the same time increases the number of cavitation bubbles in the cavity. Bubble cavitation modes created with the help of pulsations allow not only to intensify the mixing processes, but also to reduce the specific energy consumption for mixing while maintaining a high degree of homogenization and dispersion. No. 552379, characterized in that, in order to intensify the processing of the suspension by creating resonant pulsations of the liquid and reducing the specific energy iCal cost manifold for supplying liquid is provided with a pulsator installed ne its supply present lads, received information sources into account for examination 1.
