Description

(54) DEVICE FOR FLUID CLEANING

one

The invention relates to environmental protection and can be used for wastewater treatment in the chemical, oil refining, metallurgical and other sectors of the industry. A device for separating two liquids with different densities is known, which is a rectangular container equipped with three transverse partitions and a package of inclined plates located between the second and third partitions 1.

The disadvantages of this device include the fact that in it particles dispersed in a liquid are separated after their coagulation with the help of special reagents or devices.

The closest in technical essence and the achieved result is a device for cleaning fluid, including a housing with a package of obliquely mounted plates, a device for removing floating and precipitated particles 2.

The drawbacks of the device are that the removal of particles from the particles is low (about 60% of the initial concentration).

since it dispersed particles are not separated from the liquid, and the possibility of previously deposited particles falling into the liquid stream. In addition, having large dimensions, this device occupies a significant production area.

The purpose of the invention is to increase the cleaning efficiency and reduce the size of the device.

The goal is achieved by the fact that

10, a fluid cleaning device including a body with a plate pack, devices for removing floating and settled particles are provided with slide gates installed at the upper and lower edges of the plates, and the plates are made with alternating slot-like openings in the center and lateral edges.

The drawing shows a liquid cleaning device, a general view.

The device consists of a container 1 and formed by partitions 2 and 3 of the housing 4, dividing the container 1 into zones 5 and 6 of collecting precipitated and floating particles, respectively. Alternately, plates 7 with a central slit-like (; G1 sstriem 8 and plates 9 with slit-like apertures 10 made on the side faces in the direction of inclination of the plates) are mounted in case 4 in a sequential manner. In partitions 2 and 3 forming the case 4, slit-like apertures 11 are made connecting the interplate space of the package of plates 7 and 9, respectively, with zones 5 and 6. The slotted holes 11 in the partitions 2 and 3 are equipped with a spigot bolt 12. A pipe 13 is connected to the housing 4 to supply fluid for cleaning In part 4 of the housing 4, there is a pocket 14 for collecting the purified liquid with a pipe 15 for discharging it. To remove the precipitated particles, the zone 5 of the housing 4 is connected to the device 16 for removing the precipitated particles A to the zone 6 for removing the floating particles and emptying the zone respectively to remove the floating particles and the pipe 18. The device works as follows: Echip1, aemi fluid through the pipeline 13 enters the housing 4 and passes from the bottom up through sequentially alternating between them slit-like injections 8 and 10 and the plate package 7 and 9. When the liquid passes through the stack of plates in the interlamellar space occurs reorientation liquid layers. Thus, the layer of liquid on the first plate being lower, on the second plate, becomes upper, and so on. As a result of repeated changes in the orientation of the layers of liquid, substances in a liquid begin to oscillate. At the same time, particles with a low sedimentation rate adhere to particles with a higher sedimentation rate. As a result of coarsening, the particles are deposited on the plates or float to the positioned out. At the same time, the deposited particles slide along the plates 7 and 9 installed at an angle of 30-60 to the vertical to the slit-like holes 11 of the spherical shutter 12, and the floating particles move along the lower planes of the vyspraspolozhennyh plates to the slit-like holes 11 of the schnber gate 12. At opening the spigot gate 12, the precipitated particles enter the collecting zone 5 of the precipitated particles and are discharged from it through the device 16 to remove the precipitated particles, and the floating particles enter the zone 6 and are removed through it through the device 17 to remove the floating particles. The fluid cleaned in the plate pack 7 and 9 enters the pocket 14 of the housing 4 and is discharged from it through conduit 15. By repeatedly reorienting the fluid layers as it passes through the bag of vertically mounted plates provided with successive alternating slit-like openings and cutouts made respectively in the center and lateral faces of the plates in the direction of their inclination, the deposition rate of suspended particles increases and, as a result, the cleaning efficiency. In addition, the vertical arrangement of the plate pack increases the compactness of the device, which leads to a decrease in the production space occupied by the device. Claims An apparatus for cleaning a liquid, comprising a housing with a package of obliquely mounted plates, a device for removing floating and precipitated particles, characterized in that, in order to increase the cleaning efficiency and reduce its size. the device is equipped with spherical bolts M installed at the upper and lower edges of the plates, and the plates are made with alternating slit-like holes in the center and lateral faces.
