Abstract

The utility model discloses a backflow water taking device for reducing water diversion times in the technical field of chemical equipment. The backflow water taking device solves the problems that a backflow water taking device in the prior art is high in water diversion time and needs workers to stay to observe for a long term. The backflow water taking device comprises a condenser, and a to-be-condensed-gas inlet of the condenser is connected with a gas phase outlet at the top of a reaction kettle. The device further comprises a liquid outlet pipe and a backflow pipe, an upper stop valve is connected onto the liquid outlet pipe, an outlet of the upper stop valve is connected with a water tank through sight glass and a lower stop valve, a condensate liquid outlet of the condenser is connected with a collecting box, an overflow opening is arranged at the upper portion of the lateral face of the collecting box, the backflow pipe is connected with the overflow opening, and the liquid outlet pipe is connected with the bottom of the collecting box. During work of the backflow water taking device for reducing water diversion times, toluene on an upper layer flows back to the reaction kettle through the backflow pipe, water on a lower layer is discharged to the water tank through the liquid outlet pipe, and separation of the toluene and the water is finished. The backflow water taking device for reducing water diversion times reduces water diversion times, does not need special personnel to watch for a long term, saves time and labor, and is thorough and efficient in separation.

Description

A kind of reduction divides the backflow band water device of waterside number

Technical field

The utility model relates to a kind of chemical industry equipment, particularly a kind of with toluene and moisture from device.

Background technology

In the process of producing sulfonate, can volatilize the mist of toluene and water in the reactor, toluene is need to be back in the reactor to recycle, and water is to need in time to remove, for addressing this problem this, a kind of backflow band water device is arranged in the prior art, it mainly comprises condenser, the solidifying gas feed for the treatment of of condenser links to each other with reactor top gaseous phase outlet, the condensate outlet of condenser is connected with stop valve through the upright standpipe that arranges, upper stop valve outlet is through visor, lower stop valve connection water channel, and described standpipe is provided with the return duct of connecting reactor.The toluene that gaseous phase outlet in the reactor comes and the steam of water are condensed into liquid in condenser, toluene and water stratification, toluene is on the upper strata, water therefore by the overflow mode, can guarantee that toluene flows back to reactor through return duct in lower floor, water then accumulates in lower end in the standpipe, when the water in the standpipe is abundant, by upper stop valve and lower stop valve, water can be put into tank.Visor be for observe the water level situation and discharge water whether suitable, in order to avoid toluene is put into tank.Its weak point is: this device needs the observer long-time stay-at-home by visor, and in time discharges water, otherwise water can enter in the reactor in overflow, affects production efficiency.

The utility model content

The purpose of this utility model provides the backflow band water device that a kind of reduction divides the waterside number, can reduce staff's labour intensity, makes the device operation and manages convenient.

The purpose of this utility model is achieved in that a kind of reduction divides the backflow band water device of waterside number, comprise condenser, the solidifying gas feed for the treatment of of condenser links to each other with reactor top gaseous phase outlet, this device also includes drain pipe and return duct, be connected with stop valve on the described drain pipe, upper stop valve outlet is through visor, lower stop valve connection water channel, the condensate outlet of described condenser is connected collecting box, top, collecting box side is provided with overfall, described return duct links to each other with overfall, and drain pipe is connected to the collecting box bottom.

During the utility model work, the mist of toluene and water is spilled over to condenser from reactor top gaseous phase outlet, is converted into the condensation by mixing liquid of toluene and water through condenser condenses, condensate liquid is collected case and collects, leave standstill rear generation layering, it is liquid toluene at the middle and upper levels, and lower floor is water; When level of condensate was higher than overfall, upper toluene was back to reactor through return duct, was recycled; Open successively lower stop valve, upper stop valve, the water that then is positioned at lower floor begins to flow to tank through drain pipe, and whether can layering occur this moment by the liquid that visor is observed in the drain pipe, when finding that layering appears in liquid in pipe, should close immediately lower stop valve, finish separating of toluene and water.Compared with prior art, the beneficial effects of the utility model are:

But be collected liquid toluene and the backflow of water AUTOMATIC ZONING that case is collected, need not the staff guards for a long time, only need regularly observe height of water level in the collecting box, when finding lower floor's height of water level near overfall, in time water is discharged by drain pipe and get final product, greatly reduce a minute waterside number, time saving and energy saving, and separate more thorough, efficient.

As further improvement of the utility model, described return duct is provided with U-shaped aqua seal section.During work, can form water seal to return duct, avoid the interior mist recoil of reactor and cause return duct gas stifled.

As further improvement of the utility model, described return duct is separated into pipeline section one and pipeline section two through aqua seal section, pipeline section one is near feeder one side setting, pipeline section two is near reactor one side setting, the height of pipeline section one is higher than pipeline section two, form higher pressure reduction with the two ends at aqua seal section, prevent that further the mist recoil from causing return duct gas stifled.
