This novel proposition controlled pair of air-dissolving air-float system.Air-flotation system is two-way pipeline, every road pipeline is in series with air dissolved pump, motor-driven control valve, circulating water flow gauge, gate valve, vacuum breaker and dissolving respectively, after each dissolving outlet side placed in series motor-driven control valve and be a pipeline Connection Release pipe, water inlet pipe is serially connected with online turbidimeter and feed water flow gauge, air dissolved pump on the suction side pipeline is other is connected to auto-admission variable valve and vacuum pressure sensor, and dissolving top is provided with pressure transmitter and automatic exhaust device.Because this air floatation machine initiates the molten gas of form adopting two air dissolving systems, energy-conservation effect can be reached and can improve water treatment efficiency again, break down maintenance time, air dissolving system for subsequent use can also be had to work on; Because this air floatation machine 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.
Description
Technical field:
Basis is novel relates to technical field of sewage, is specifically related to controlled pair of air-dissolving air-float system.
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 a kind of controlled pair of air-dissolving air-float system.Because this air floatation machine 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: controlled pair of air-dissolving air-float system, comprise air supporting casing, two-way pipeline in parallel after having pipeline to draw bottom the water part of air supporting casing, every road pipeline is in series with air dissolved pump, motor-driven control valve, circulating water flow gauge, gate valve, vacuum breaker and dissolving respectively, after each dissolving outlet side placed in series motor-driven control valve and be a pipeline Connection Release pipe, 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 initiates the molten gas of form adopting two air dissolving systems, can reach energy-conservation effect and can improve water treatment efficiency again, break down maintenance time, air dissolving system for subsequent use can also be had to work on; Because this air floatation machine 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.

Embodiment:
Be described further originally novel below in conjunction with accompanying drawing:
As shown in Figure 1, controlled pair of air-dissolving air-float system comprises air supporting casing 1, two-way pipeline in parallel after having pipeline to draw bottom the water part of air supporting casing 1, every road pipeline is in series with air dissolved pump 8, motor-driven control valve 6, circulating water flow gauge 5, gate valve, vacuum breaker and dissolving 3 respectively, motor-driven control valve 6 regulates pressure and the flow of dissolving 3, the vapour-liquid ratio of needs can be produced, after each dissolving 3 outlet side placed in series motor-driven control valve 6 and be a pipeline Connection Release pipe 10, 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.Air dissolved pump 8 on the suction side pipeline is other is connected to auto-admission variable valve 9 and vacuum pressure sensor 7.Auto-admission variable valve 9 can regulate the air input of air dissolved pump 8.
Dissolving 3 top is provided with pressure transmitter 2 and automatic exhaust device 4, and 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.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.
As can be seen from 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 6 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 liquid level is with entering increasing and reducing of gas, 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.
Because the parameter of air dissolved pump itself limits, said system can only change within the specific limits, in order to the change in wider scope endoadaptation water water quality and flow, this novel pair cover automatic air-float system of establishing coordinates adjustment to achieve the above object, when water water quality containing suspended substance and flow in setting range, open a set of air dissolving system, now energy-conservation; When water water quality exceeds setting range containing suspended substance, open two cover air dissolving systems, now improve treatment effect; When a set of air dissolving system breaks down maintenance, there is redundant system.
