Abstract

The invention relates to a water pressure type air dissolving device, belonging to the field of manufacture of mechanical equipment. The water pressure type air dissolving device comprises an external casing, an air inlet device and water inlet and outlet pipes, wherein the external casing consists of a semicircular body at the lower part and a conical body at the upper part; a lower area A formed by the semicircular body is a diffusion mixing area, an upper area B formed by the conical body is a gradually-reduced squeezing area, one or more groups of ejectors are mounted at the lower part of the area B, and horn holes in the lower part of the ejectors extend into the area A; the water inlet pipe connected with a water inlet pump is connected to the top ends of the ejectors, and the water outlet pipe is connected with the top part outside the conical body. The air solubility of the air dissolving device reaches saturation, the oxygen utilization rate is 100 percent, the investment is reduced by 25 percent compared with that of a traditional aeration method, the energy consumption efficiency ratio is improved by 4-6 folds, and meanwhile, the device adopts negative pressure self-suction air intake mode without using an air blower, so that no noise is generated.

Description

The molten gas equipment of hydraulic type

Technical field

The present invention is the molten gas equipment of hydraulic type, belongs to plant equipment and manufactures field.

Background technology

The molten gas of hydraulic type be utilize glassware for drinking water have can not be compressed but can by infiltration, gas can be compressed and compression after there is the characteristic of expansive force, take to apply that external force (pump head) is extruded gas self-priming in water and cone physical arrangement forms the double mode dissolved gas method that nature supercharging expands.

The molten gas equipment of one that existing market is used is to utilize air compressor machine inflation or jet inflation, under the pressure of air compressor machine or water pump, gas is dissolved in water.This kind of molten gas equipment is generally a cylinder, ejector is installed in its upper side space or is directly inflated by air compressor machine, its upper side water inlet, bottom water outlet, the deficiency existing is that the mixed dissolution of gas and water is disposablely to be completed by ejector or compressed air in equipment, and the solubility of gas is low.In addition, due to the compressed rear generation expansive force of gas, discharge and can form vent plug phenomenon at device upper space, for discharging unnecessary gas, gas vent must be offered in device top, because device is worked under certain process stage, in the time of emptying, can form tornado effect, part dissolved air water is followed residual gas and is discharged together, has reduced the utilization rate of dissolved air water, if what supply with is pure oxygen gas, can cause the waste of pure oxygen resource.

Summary of the invention

The present invention, just in order to overcome above-mentioned deficiency, provides a kind of improved hydraulic type molten gas equipment, and gas solubility can reach 100%, and resource utilization is high.Main improvement is to change equipment contour structures, Inlet and outlet water direction and adopts the method for double mode extruding gas dissolution in water, to reach gas saturation solubility, and avoids producing vent plug phenomenon in equipment.

Specifically implement like this: the molten gas equipment of hydraulic type, comprise shell body, ejector, inlet duct, water inlet pipe and water outlet pipe, it is characterized in that equipment is made up of the semicircular bodies of bottom and the bullet on top, the A district, bottom that semicircular bodies forms is diffusion mixed zone, the B district, top that bullet forms is convergent anallobar, the horn mouth that one or more groups injector is arranged on bottom, B district and injector bottom extends in A district, the water inlet pipe joining with intake pump is connected to the top of injector, and outlet pipe is connected with the top of cone.

By one or more groups injector is installed at device interior, water pump is made former high pressure water current hydrostatic head convert kinetic energy to and is become high-speed jet by injector, form region of no pressure at nozzle place cavity, the water flow pressure and the speed that enter region of no pressure are changed, current and gas mix in A district.Because delivery port is at top, B district, fluid-mixing can only rise and enter B district, because B district is upper cone structure, fluid is more and more less at the rising space in B district, and in the situation that flow is constant, fluid velocity can be more and more faster, unit pressure can be more and more higher, and gas is again subject to secondary extrusion and dissolves.Gas be once dissolved in the water be under the high pressure conditions of injector moment complete, secondary is dissolved in the water and under cumulative pressure state, carries out when long, it is supplementing and continuity of dissolving of first compression that gas is dissolved in the water by secondary, and the secondary of gas dissolves pressure and comes from that driving source and B district taper physical arrangement form.Gas 100% is added in liquid in this equipment after second-compressed is dissolved, and therefore in equipment, can not produce vent plug phenomenon, without offering exhaust outlet on equipment top.

If with the dissolved gas of this equipment be pure oxygen, for supporting oxygenerator is normally worked, must one pure oxygen inlet duct be set outward at housing, described pure oxygen inlet duct connects the gas outlet of oxygenerator, with the outlet pressure of balance oxygenerator.

Outlet pipe of the present invention is provided with flowing water Valve, utilizes flowing water Valve to adjust switch size, the fluid pressure in generation conditioning equipment.

The gas solubility degree of reaching capacity of this equipment, coefficient of oxygen utilization 100%, reduces investment outlay 25% than traditional aeration, and energy consumption efficiency, than improving 4-6 doubly, adopts negative pressure self-suction air inlet simultaneously, does not use blower fan, so do not produce noise.This equipment can be used for producing heavy-oxygen-enriched water, substitute aeration device for treating sewage, replace dissolving, give river course oxygenation; If throw in graininess or the minor diameter Ball-type packing of some in equipment, as long as sewage water inlet pipe is connected with unit fixed on water pump suction with blow-down pipe, this equipment just can be used as miniature complete sewage-treatment plant and uses.
