Abstract
The utility model discloses a reverse-osmosis starting device, comprising a bypass pipe and a bypass electrically operated valve which are disposed at a high-pressure pump. Pressure slowly rises and falls when a system is started and shut down. The reverse-osmosis starting device has the beneficial effects that cost can be reduced efficiently and the service life of the reverse-osmosis starting device can be prolonged.
Description
Technical field
The utility model relates to the Reverse Osmosis Water Treatment Technology application, particularly a kind of counter-infiltration starting drive.
Background technology
In counter-infiltration system, usually be designed with starting drive, in order to prevent that high-pressure pump from starting and pressure while closing suddenly rises or descends and causes membrane component to damage, the general solution that adopts is: adopt frequency converter or soft initiator to alleviate, still this way has strengthened equipment cost.Or be provided with after high-pressure pump and electronicly drive slowly valve, but every subsystem start and stop need to open and close the electronic valve of opening slowly repeatedly, can reduce like this service life of valve.Or by flushing valve is changed into and drives slowly motor-driven valve, but rear two kinds of methods have a same problem, and the crushing that need to overcome high-pressure pump and mating valve due to low-pressure water just enters reverse osmosis unit, therefore requires the higher pressure guarantee rinsing requirement of former water.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of counter-infiltration system starting drive.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of counter-infiltration starting drive, locate a bypass line in parallel (5) at high-pressure pump (2), bypass motor-driven valve (3) is installed on bypass line, it is characterized in that, former water (1) when system starts after pressurization enters reverse osmosis membrane (4) by high-pressure pump (2) and bypass motor-driven valve (3) simultaneously, after high-pressure pump (2) starts, bypass motor-driven valve (3) cuts out, and is provided with flow measurement device (6) simultaneously on bypass line.
The counter-infiltration starting drive that utilizes the technical solution of the utility model to make; realized that counter-infiltration system leaves, system pressure rising and decline while shutting down; having eliminated the high-pressure pump start and stop impacts the film system; and the each startup-shutdown of system while rinsing the former water (1) after pressurization owing to entering reverse osmosis membrane (4) by high-pressure pump (2) and bypass motor-driven valve (3) simultaneously; the corresponding increasing of intake tunnel; therefore reduce the pressure requirement higher to former water, guaranteed the normal flushing of system.
Description of drawings
Fig. 1 is the structural representation of counter-infiltration starting drive described in the utility model;
In figure, 1, Yuan Shui; 2, high-pressure pump; 3, bypass motor-driven valve; 4, reverse osmosis membrane; 5, bypass line; 6, flow measurement device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model being specifically described, is the structural representation of counter-infiltration starting drive described in the utility model as Fig. 1.As shown in the figure, a kind of counter-infiltration starting drive, be included in high-pressure pump (2) and locate to do a bypass line (5), described bypass motor-driven valve (3) is arranged on the bypass line of high-pressure pump, is provided with flow measurement device (6) simultaneously on bypass line.
The technical program is done a bypass line at the high-pressure pump place, and on bypass line, the bypass motor-driven valve is installed.The bypass motor-driven valve is in opening when each device starts, former water (1) after pressurization is owing to entering reverse osmosis membrane (4) by high-pressure pump (2) and bypass motor-driven valve (3) simultaneously, the corresponding increasing of intake tunnel, therefore reduce the pressure requirement higher to former water, guaranteed the normal flushing of system.Rinse and finish rear high-pressure pump startup, this moment, most of water refluxed by the bypass motor-driven valve, so the pressure of system is very low, along with bypass motor-driven valve slowly closing, reflux and reduce gradually, the intake pressure of film system also increases thereupon gradually, has realized the purpose of slow supercharging.Until the bypass motor-driven valve cuts out fully, system brings into operation.
The bypass motor-driven valve is slowly opened when each system-down; along with the bypass motor-driven valve is slowly opened, reflux and strengthen gradually, the intake pressure of film system also reduces thereupon gradually; realized the purpose of slow step-down, until the bypass motor-driven valve is opened high-pressure pump afterwards fully, shut down.System starts to rinse, and rinses and finishes rear system-down.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, within belonging to protection domain of the present utility model.
