Description
Technical field:
Basis is novel relates to technical field of sewage, is specifically related to the adjustable dissolving of vapour-liquid ratio.
Background technology:
The maxima solubility of air in water depends primarily on pressure, water temperature and water quality, pressure is higher, water temperature is lower, then the saturation solubility of air in water is larger, according to the character of gas and liquid, and the change of temperature, pressure, gas saturation solubility is in a liquid different, in order to capture suspended substance most, bubble in air supporting should be little as far as possible, and be evenly distributed, at present, gas (air) saturation solubility in water depends on the temperature and pressure of water, the saturation solubility of gas (air) in water under differing temps and pressure condition is also different, the pressure of vapour-liquid ratio many uses manual shift pump that the multiphase pump that air floatation machine uses regulates, vacuum tightness, gas flow, the flow of recirculated water controls vapour-liquid ratio, the relative total inflow of recirculated water sets, for the change of water quality of sewage and the change of the water yield, air dissolving system cannot make corresponding reaction, thus reduction air flotation effect, simultaneously air floatation machine is also made to be not suitable with change of water quality and treatment capacity changes the impact brought, treatment effect is undesirable.
Summary of the invention:
In order to solve the problem, basis is novel to be intended to propose the adjustable dissolving of a kind of vapour-liquid ratio.Because this dissolving air dissolving system adds under meter and variable valve, install online turbidimeter and under meter additional at influent side simultaneously, vapour-liquid ratio can be realized and automatically can regulate adaptation influent quality and fluctuations in discharge, improve molten gas efficiency.
This novel technical scheme is: vapour-liquid ratio is adjustable dissolving, comprise air supporting casing, air dissolved pump, motor-driven control valve, circulating water flow gauge, gate valve, vacuum breaker and dissolving is in series with after having pipeline to draw bottom the water part of air supporting casing, Connection Release pipe after dissolving outlet side placed in series motor-driven control valve, releasing tube is positioned at above water inlet pipe.Water inlet pipe is serially connected with online turbidimeter and feed water flow gauge.
In such scheme, air dissolved pump on the suction side pipeline is other is connected to auto-admission variable valve and vacuum pressure sensor.Dissolving top is provided with pressure transmitter and automatic exhaust device.
This is novel has following beneficial effect: because this air floatation machine dissolving adds circulating water flow gauge and pressure transmitter as feeler mechanism, add auto-admission variable valve and motor-driven control valve, auto-admission variable valve and motor-driven control valve and feeler mechanism form closed-loop control, install online turbidimeter and under meter additional at influent side simultaneously, according to the data that online turbidimeter and under meter draw, the flow of the given saturated dissolved gas of upper computer, send instruction, feeler mechanism regulates auto-admission variable valve and motor-driven control valve to reach the circulating water flow of the saturated dissolved gas of setting, realize vapour-liquid ratio and automatically can regulate adaptation influent quality and fluctuations in discharge, improve molten gas efficiency.

Embodiment:
Be described further originally novel below in conjunction with accompanying drawing:
As shown in Figure 1, vapour-liquid ratio is adjustable, and dissolving comprises air supporting casing 1, air dissolved pump 8, motor-driven control valve 6, circulating water flow gauge 5, gate valve, vacuum breaker and dissolving 3 is in series with after having pipeline to draw bottom the water part of air supporting casing 1, motor-driven control valve 6 regulates pressure and the flow of dissolving 3, Connection Release pipe 10 after dissolving 3 outlet side placed in series motor-driven control valve 6, releasing tube 10 is positioned at above water inlet pipe 11.Water inlet pipe 11 is serially connected with online turbidimeter 13 and feed water flow gauge 12.This novel numerical value according to intake online turbidimeter 13 and feed water flow gauge 12 sets the circulating water flow needed for upper computer.
Air dissolved pump 8 on the suction side pipeline is other is connected to auto-admission variable valve 9 and vacuum pressure sensor 7.The flow regulating the air input of auto-admission variable valve 9 to realize the mixed solution of saturated solution gas by the numerical value of vacuum pressure sensor 7 adapts to the change of influent quality and the change of flooding velocity.
Lower Fig. 2 is the rational curve of certain air dissolved pump, and in Fig. 2, each curve is pump performance under different vapour-liquid ratio.
Can find out in Fig. 2, air dissolved pump vapour-liquid ratio when pressure difference is different with flow is also different, when pressure-controlling is between 0.5 ~ 1.0MPa, also there is respective change in the flow of pump and vapour-liquid ratio thereupon, as long as control the water inlet vacuum tightness of air dissolved pump, the flooding velocity controlling dissolving and pressure well, the vapour-liquid ratio of needs can be produced, the gas-liquid mixed flow of the qualified micro-bubble that namely water treatment needs.
During this is novel, according to the online turbidimeter 13 of water inlet and feed water flow gauge 12, circulating water flow needed for upper computer setting, the flow of the mixed solution of the saturated solution gas namely needed, by the pressure and the flow that regulate the motor-driven control valve 6 before and after dissolving 3 to regulate dissolving 3, closed-loop control is formed with motor-driven control valve by pressure transmitter 2 and circulating water flow gauge 5, finally reach set(ting)value, the flow simultaneously regulating the air input of auto-admission variable valve 9 to realize the mixed solution of saturated solution gas by the numerical value of vacuum pressure sensor 7 adapts to the change of influent quality and the change of flooding velocity.
Dissolving 3 top is provided with pressure transmitter 2 and automatic exhaust device 4.Dissolving 3 liquid level is with entering increasing and reducing of air inlet body, when liquid level drops to optimum height, now can not discharged from automatic exhaust device 4 to the gas in water by molten, thus make liquid level remain on optimum height always, ensure maximum gas-to-liquid contact space, increase molten tolerance and molten gas effect.
