The equipment that a kind of automatic gauge titanium tetrachloride is reinforced
Technical field:
The utility model relates to the reinforced equipment of a kind of automatic gauge titanium tetrachloride, especially for gram Raul method titanium sponge production reduction operation, adds the automatic metering equipment of raw material titanium tetrachloride in reduction process.
Background technology:
Present domestic titanium sponge production all adopts stainless steel storage tank to add the titanium tetrachloride charging system that flowmeter or magnetic drive pump add flowmeter, is the flow measurement mode, and its shortcoming is that investment is big, measures inaccurately, and error is 8%~10%; Make TiCl aborning
4Addition can accurately not carry out according to technological parameter, cause the titanium sponge product to be guaranteed being difficult to qualitatively.
The utility model content:
The utility model purpose provides the reinforced equipment of a kind of automatic gauge titanium tetrachloride, reduces investment, accurate measurement, and the quality of guarantee titanium sponge product solves the problems referred to above that background technology exists.
The technical solution of the utility model is: the equipment that a kind of automatic gauge titanium tetrachloride is reinforced, comprise stainless steel storage tank, diaphragm metering pump, reactor, DCS control system, stainless steel storage tank is connected with diaphragm metering pump, reactor successively by pipeline, and the DCS control system connects diaphragm metering pump.
The DCS control system is public scattered control system, can reach the purpose of setting flow value by the rotating speed that frequency converter is controlled diaphragm metering pump, current flow velocity is conformed to technology, and the situation of feeding in raw material is carried out automatic gauge, control.
The utility model also is provided with spinner flowmeter, is arranged on the pipeline behind the diaphragm metering pump, and spinner flowmeter shows whether current output flow velocity is steady, and the duty of diaphragm metering pump is monitored.
The utility model also is provided with damper behind diaphragm metering pump on the pipeline, be provided with the damper pressure pulse that measuring pump produces that is used for eradicating a mental barrier behind the diaphragm metering pump when work, guarantee the pressure held stationary in the titanium tetrachloride feed-line, make metering more accurate.
The utility model also is provided with counterbalance valve behind diaphragm metering pump on the pipeline, the material of diaphragm metering pump output has certain pressure oscillation, after passing through counterbalance valve, counterbalance valve can make the material pressure of output tend to be steady, at the metering diaphragm delivery side of pump siphonage is arranged in addition, this moment, counterbalance valve can be subdued because the flow that siphon produces and the fluctuation of pressure make the metering of flow more accurate.
The said pipeline of the utility model is single stove independence stainless steel pipeline, and diaphragm metering pump is the diaphragm metering pump of single stove; Stainless steel storage tank is the overall storage tank of many stoves, and every stove of many stoves all has single stove independence stainless steel pipeline (the titanium tetrachloride feed-line of single stove), independent diaphragm metering pump.
Said spinner flowmeter is a glass rotameter, is convenient to observe monitor.
The beneficial effects of the utility model are: the utility model compared with prior art, small investment, accurate measurement error are<2%, meet the requirement of reducing process fully; Have good practicability more than 10 years service life.
Description of drawings:
Accompanying drawing 1 is the utility model example structure schematic diagram;
Among the figure: 1, stainless steel storage tank, 2, damper, 3, diaphragm metering pump, 4, spinner flowmeter, 5, counterbalance valve, 6, reactor, 7, the DCS control system.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The equipment that a kind of automatic gauge titanium tetrachloride is reinforced comprises stainless steel storage tank 1, diaphragm metering pump 3, reactor 6, DCS control system 7, and stainless steel storage tank is connected with diaphragm metering pump, reactor successively by pipeline, and the DCS control system connects diaphragm metering pump.
The utility model also is provided with damper 2, spinner flowmeter 4, counterbalance valve 5, is separately positioned on the pipeline behind the diaphragm metering pump.
The pipeline of present embodiment is single stove independence stainless steel pipeline, and diaphragm metering pump is the diaphragm metering pump of single stove; Stainless steel storage tank is the overall storage tank of 12 stoves, and every stove of 12 stoves all has single stove independence stainless steel pipeline (the titanium tetrachloride feed-line of single stove), independent diaphragm metering pump, and spinner flowmeter is a glass rotameter.
Embodiment more specifically:
With reference to accompanying drawing, the stainless steel storage tank 1 of titanium tetrachloride has a liquid level gauge in its left side, and excessive in order to prevent that storage tank from flowing to the pressure of diaphragm metering pump generally speaking, the liquid level in the storage tank is no more than 3/4 of tank body height.All is that stainless valve to slow down titanium tetrachloride corrosion to valve body, assurance product quality to diaphragm metering pump and by diaphragm metering pump to the valve that adopts the reactor by storage tank.
Open the valve on all pipelines, the flow value of diaphragm metering pump is set on DCS control system 7, start diaphragm metering pump and carry out TiCl
4Reinforced work, observe TiCl by glass rotameter
4Whether flow is steady, and diaphragm metering pump 3 is transported on the DCS control system 7 by the signal of telecommunication with flow value, and operating personnel can monitor TiCl by the DCS control system
4Present flow rate and integrated flow value, reach accurate control TiCl
4Reinforced purpose.
