Abstract
An underwater gas fine-grained gas cutting mechanism belongs to the field of environmental engineering and the like. An oxygenation aeration water purification device is a special water purification device which is developed specially aiming at sewage treatment. In the working engineering of the equipment, the external gas is introduced into the sewage through the gas guide pipe after relatively pure oxygen is obtained through the gas purification device, and because the gas is not broken at the tail end of the gas outlet of the traditional equipment, the input oxygen is not fully dissolved in the water and then floats out of the water surface in the form of larger bubbles, the underwater gas fine-grained gas cutting mechanism can break the bubbles led out from the gas guide pipe, so that the dissolving rate of the gas in the working environment is improved, and the energy loss caused by the unit cubic meter of oxygen dissolving amount is reduced.
Description
Technical Field
The invention belongs to the field of environmental engineering and the like, and particularly relates to an underwater gas fine-grained gas cutting mechanism.
Background
In recent years, with the improvement of the requirement of our country for environmental protection treatment, the sewage treatment technology has been developed rapidly, and the development of sewage treatment equipment aiming at various environmental problems has also developed, for example, an oxygen-increasing aeration water purification equipment is a special water purification equipment developed specially for sewage treatment. The basic working principle of the device is to promote the photosynthesis of plants in water and the degradation of microorganisms by increasing the dissolved oxygen in water so as to achieve the aim of purifying sewage.
In the sewage treatment process of the aeration equipment, the smaller the size of bubbles introduced into the sewage is, the larger the total mass transfer coefficient of oxygen is, the higher the oxygen utilization rate is, and the more favorable the oxygen is to be transferred into the sewage. The bubbles generated when the outside gas enters water through the gas guide tube are too large, and the sizes of the bubbles can be increased along with the continuous coalescence of the bubbles during the floating, so that the gas outlet is provided with the gas cutting mechanism to promote the fine granulation of the bubbles, thereby effectively reducing the sizes of the bubbles. Therefore, the research on the air bubble fine-grained mechanism has important significance for improving the aeration effect.
Disclosure of Invention
The invention aims to design a fine grain gas cutting mechanism aiming at the problem that the conventional underwater aeration equipment has low dissolved oxygen rate due to insufficient broken bubbles. The mechanism is connected to the end part of the air outlet, and the oxygen guided out of the air guide pipe is crushed along with the rotation of the end part of the aerator, so that the dissolution rate of the oxygen in water is improved.
The invention comprises an air duct 1, a supporting arm 2, a lower layer cutter 3, a middle layer cutter 4, an upper layer cutter 5 and a cutter frame 6. Wherein:
(1) the external gas transmission device is connected with the gas guide tube 1 through the gas inlet end.
(2) The supporting arm 2 is connected with the air duct 1 through a bolt.
(3) The support arm 2 is intended to support a tool holder 6 to which a tool can be fixed by welding or bolting.
(4) The cutter of the invention is divided into an upper layer cutter 5, a middle layer cutter 4 and a lower layer cutter 3, wherein the lower layer cutter 3 (two cutters) are distributed diagonally at 180 degrees and fixed on a supporting cutter frame 6 at different angles with the horizontal plane of the supporting cutter frame 6; the middle layer cutters 5 and the upper layer cutters 6 are uniformly distributed on the same layer of cutter frame in a staggered mode, wherein the distribution mode of the cutters 5 (two cutters) is the same as that of the cutter 3, and the cutters 6 (two cutters) and the cutters 5 are vertically distributed and are positioned on the same horizontal plane with the supporting cutter frame 6.
When the cutter is installed, the blade of the cutter is consistent with the rotation direction of the end part of the aeration mechanism.
Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the invention without limiting the invention.
Fig. 1 is a front view of the present invention for explaining a connection manner between members.
Fig. 2 is a view of the lower tool 3 of the invention attached to a tool holder 6 for explaining the distribution of the tools 3 on the tool holder.
Fig. 3 is a diagram of the connection of the middle layer cutter 4 and the upper layer cutter 5 of the present invention to the tool holder 6 for explaining the distribution of the cutters 4, 5 on the tool holder.
Fig. 4 is a schematic diagram of the operation of the present invention for explaining the effect of fine grain of gas passing through the gas cutting mechanism.
The working process of the invention is as follows:
referring to fig. 4, the working principle of the gas crushing of the present invention is shown. The external oxygen is conveyed into the operation water area through a pipeline, the generated bubbles are large when the external oxygen does not pass through the cutter mechanism, and the dissolved oxygen rate in water is low. After passing through the air cutting cutter, the large-size air bubbles are crushed into small air bubbles with different sizes through the combined use of the three layers of cutters. Obviously, the dissolution rate of the crushed gas in water is greatly improved.
The invention has the beneficial effects that:
as the country attaches more importance to the environmental problem, the oxygen aeration equipment is widely applied to the fields of sewage treatment and the like, and the oxygen utilization rate in water is not high due to the immature technology, so that the resource waste and the energy consumption are indirectly caused. The underwater gas fine-grained gas cutting mechanism can crush bubbles and improve the dissolution rate of oxygen in water, thereby reducing the consumption of dissolved oxygen energy.
