Abstract

PURPOSE:To carry out the agitation of water with good energy efficiency by branching a branch elastic pipe provided with an injection part at its leading end from an appropriate site of the operating part of an elastic pipe similarly furnished with an injection part at its leading end, and moving the elastic pipe with the reaction, etc. of a fluid spouted from both injection parts. CONSTITUTION:The operating part 2 of an appropriate elastic pipe 1 provided with an injection part 3 at the leading end is positioned in the working region in water W, the base part of the elastic pipe 1 rising vertically from almost the center of the working region is fixed by a fixing part 4 at the upper outside of the region, and a branched elastic pipe 1A similarly furnished with an injection part 3A is branched from the appropriate site of the operating part of the elastic pipe 1. The combined movements of waving, twisting, bending, turning, etc. are caused to the pipes 1 and 1A by the reaction, etc. of an optional fluid spouted from both injection parts 3 and 3A. The planar working region is stirred by the movements and mainly by the irreproducible action of both injection parts, and the agitation, aeration, etc. in the water are carried out with good energy efficiency.

Description

[Detailed description of the invention] The present invention mainly relates to agitation (including prevention of consolidation) in water.
, aeration (including air backwashing), etc.

In recent years, water stagnation due to land reclamation, whether seawater or freshwater,
It is well known that water quality is significantly deteriorating due to lack of dissolved oxygen, deposition of harmful sludge, etc. Such water treatment methods can be roughly divided into treatment of domestic water, tap water, industrial water, agricultural water, etc. for use or during use, and treatment of wastewater after use. During these treatments, it is often necessary to perform a pre-stirring action, a pre-aeration action, or a combination of both. In addition, it is necessary to compact the generated sludge, prevent its adhesion, and remove and move the sludge.In addition, it is necessary to perform aeration-related treatments such as biological treatment, which is the mainstay of wastewater treatment (recently, pre-treatment of water (also used).

Currently, these methods require large equipment such as sludge collectors to be installed during the treatment of water, sewage, and wastewater, but such sufficient equipment is not available for small biological treatment tanks such as human waste septic tanks. There was also room to consider rational methods for air backwashing of biological fixed beds.

In view of this problem, the present invention has an extremely simple and inexpensive structure in which the actuating part of an appropriate elastic tube with a spouting part at its tip is submerged in water in order to produce a stirring or aeration effect. The base of the elastic tube is located in the action area and stands upright from the approximate center of the action area, and the base part is fixed outside the upper area, and the branch elastic tube is provided with a spouting part at the same tip from the appropriate location of the actuation part of the elastic tube. A pipe is arranged, and the elastic pipe and the branch elastic pipe are given complex movements such as waviness, twisting, bending, and reversal due to the reaction force of any fluid ejected from both ejection parts, and this movement mainly causes both The present invention is intended to provide a water treatment method in which a spouting part performs non-reproducible movement in a substantially sliding state over a planar action area, and is configured to perform a stirring, rice-boiling, etc. action in water.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

An elastic tube↓ (hose, tube) placed in any underwater W such as water or a chemical solution is a tube capable of pumping a single fluid such as gas or liquid, and the material is elastically deformable such as waviness, twisting, bending, etc. shall be possible. Elastic tube↓
The actuating part 2 is located along the planar action area of the water W, and has an appropriate spouting part 3 disposed at its tip for spouting fluid in the axial direction. The base side of the elastic tube ↓ rises upward from the approximate center of the action area in a right-angled direction, but a fixing part 4 is provided outside the upper area, and at least the fixing part 4 or the fixing part 4 Fluid pumps such as pumps and compressors (not shown) at locations further away
Connect to a longer pipe. A holding part 5 is provided below the fixing part 4, and the holding part 5 holds the elastic tube 1 so that it can be freely twisted.

A branch elastic tube IA having an appropriate spout portion 3A at its tip is disposed from a proper position of the actuating portion 2 of the elastic tube ↓ located along the planar action area in the water W. ↓ and the branch elastic tube IA may undulate, twist, bend, or
It is configured to perform complex movements such as rotation and reversal, and as a result of this movement, both jetting portions 3 at the tip mainly perform non-reproducible movements in a substantially sliding state in a planar action area.

In FIG. 2, A indicates a biological fixed bed that requires backwashing.

As described above, in the present invention, the actuating part 2 of a suitable elastic tube 1 provided with a spouting part 3 at the tip is located in the action area of the water W, and the elastic tube rises in a right angle direction from approximately the center of the action area. ” is fixed 4 outside the upper region, and a branch elastic tube IA having a spouting portion 3A at the tip thereof is arranged at a suitable position from the actuating portion 2 of the elastic tube 1, and spouting from both spouting portions 3.3A is provided. Due to the reaction force of any fluid, etc., the elastic tube ↓ and branch elastic tube IA
is subjected to complex movements such as waviness, twisting, bending, and reversal, and as a result of this movement, both the ejection parts 3.3A mainly perform non-reproducible movements in a substantially sliding state in the planar action area,
This is a water treatment method configured to perform underwater agitation, agitation, etc., and the applicant's experimental results also show that when the elastic tube 1 is a single tube, the movement trajectory of the jetting part 3 is mainly determined by the material of the tube and its length. Due to the influence of speed, dead space remains even if the vehicle moves in the same trajectory within a generally fixed range. This is because even if there is a change in the pressure supply or the outside world over time, it is less affected by the change. Therefore, by arranging the branch elastic tube IA of an appropriate length from the appropriate position of the actuating part 2, the composite The movement is changed so that both the ejection parts 3.3A perform non-reproducible movements, and a highly efficient device with uniform operation within the action area without dead space has been created.

The pressure of the fluid to impart compound motion to the elastic tube 1 and the branch elastic tube IA is determined under relatively low pressure conditions (approx. Because only a small amount of water is needed, even in human waste septic tanks, etc., where sufficient treatment equipment was not available in the past, water can be used in existing water supply systems without having to use a pump to pump out water. It is capable of stirring and stirring the action area at the bottom, and can prevent compaction and adhesion of sludge.

Since it is a simple device with only the elastic tube ↓ including the branch elastic tube IA and the ejection part 3, it is much more economical than conventional devices, and the energy released only at the ejection point is minute. It is extremely energy efficient (and there is a new field in its use of slow-acting, which affects the entire required area).
