Abstract
The utility model relates to a material conveying system, particularly to a chloromethane pressurizing and conveying system. The system comprises a material tank and a conveying pipeline, and is characterized in that a discharge valve is arranged at the discharge port of the material tank, and is sequentially connected with a pressurizing pump and a constant pressure tank through pipelines; and the constant pressure tank is connected with a reaction container through a pipeline. Chloromethane is stored in a low pressure material tank, when the chloromethane is used for processing, the discharge valve is opened and chloromethane enters a conveying pipeline and is pressurized by the pressurizing pump. The pressure of chloromethane coming out of the pressurizing pump can fluctuate high and low, and the constant pressure tank is used for carrying out constant pressure operation, which enables output chloromethane to enter the reaction container with constant pressure.
Description
Technical field
The utility model relates to a kind of material-transporting system, especially relates to a kind of pressurizing transmission system of chloromethanes.
Background technique
Use chloromethanes to process as industrial chemicals, traditional practice be with chloromethanes with steel cylinder fill, nitrogen pressure, when needs use chloromethanes, open cylinder valve, chloromethanes outwards discharges under the effect of internal pressure.This mode cost is higher, and has certain potential safety hazard in transportation and preservation process.Because the air pressure in the steel cylinder can constantly reduce along with the release of chloromethanes, therefore be difficult to the monitoring that the chloromethanes use amount is prepared simultaneously.The patent No. is that 200420016055.3 model utilitys disclose a kind of Pneumatic conveyer, it comprises initial feed bin, transmitter and discharger and terminal feed bin, initial feed bin is connected by pipeline with transmitter, conveyance conduit is connected with the transmitter bottom, pipeline is connected with discharger by elbow, the discharger bottom is fitted with pressurized machine by pipeline connecting terminal feed bin on the delivery line between transmitter and the discharger.The utility model can with feedway by by any to a bit, to multiple spot, four kinds of modes design to multiple spot, multiple spot to any and multiple spot for a bit.Carry if utilize this technological scheme to carry out chloromethanes, then exist pressure instability, be unfavorable for carrying out flow control, also exist the safety measure of overvoltage protection simultaneously, have certain potential safety hazard.Patent No. is that 02807206.5 patent of invention discloses a kind of fluid delivery system, comprises Coriodis mass flow meter, pump, recycle valve and/or back-pressure valve.Described fluid delivery system does not need air separator and filter just can prevent from multi-phase fluid stream is measured.Coriolis mass flow meter measurement is transported to the density value of the fluid product of point of destination from fluid source.Wherein at least one is made comparisons with the density value that records and upper threshold value and lower threshold value.If the density value that records surpass described upper threshold value or lower threshold value wherein at least one, flowmeter just turns off pump automatically and cuts out back-pressure valve, stops fluid product being transported to point of destination from fluid source, thereby has prevented from multi-phase fluid stream is measured.The structure of this technological scheme and calculating process are comparatively complicated, and cost is higher, and can't reach comparatively fixed pressure.
Summary of the invention
The utility model mainly is to solve the existing in prior technology pressure instability, have potential safety hazard, complex structure, the high technical problem of cost, and the pressurizing transmission system of a kind of simple in structure, safe, stable gas pressure, easy to operate chloromethanes is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of pressurizing transmission system of chloromethanes, comprise material pot and delivery line, the discharge port that it is characterized in that described material pot is provided with a discharge valve, discharge valve connects suction booster and constant voltage jar in turn by pipeline, and the constant voltage jar links to each other with reaction vessel by pipeline.Chloromethanes is stored in the low pressure material pot, using chloromethanes to add man-hour, open discharge valve, chloromethanes enters in the conveyance conduit, carry out supercharging by suction booster, the pressure of the chloromethanes that comes out from suction booster has the height fluctuation, carries out constant voltage operation by a constant voltage jar, makes the chloromethanes of output have a constant pressure and enters reaction vessel.
As preferably, described constant voltage jar links to each other with material pot by a bypass conduit, and this bypass conduit is provided with a relief valve.Excessive when the pressure of constant voltage jar, the constant voltage jar can't effectively be regulated excessive pressure, and discharge too much chloromethanes by a relief valve this moment, and the chloromethanes that discharges is back in the material pot by bypass conduit.
As preferably, the pipeline between described discharge valve and the pressure charging valve is provided with a filter.Filter can filter the impurity in the chloromethanes of exporting from material pot, makes it can reach the required purity requirement of reaction.
As preferably, the pipeline between described manostat and the reactor is provided with a flowmeter.In fill process, the operator need detect flow, thereby judges the total amount that enters the chloromethanes in the reaction vessel.Because the flowmeter survey here is the constant voltage chloromethanes that flows out from the constant voltage jar, so the measurement of this flow is very accurately.
As preferably, described manostat is a pulse constant voltage jar.Because from the pressure surge that chloromethanes produced of supercharging output mainly is a pulse ripple, so pulse constant voltage jar can effectively be eliminated this fluctuation.
As preferably, described material pot is provided with a safety valve.Material pot has a safety pressure value, when the pressure in it during greater than this safety pressure value, need carry out pressure release to it, and this safety valve has just played the effect of pressure release.
The beneficial effect that brings of the present utility model is, the pressurizing transmission system of having solved the existing in prior technology pressure instability, have potential safety hazard, complex structure, the high technical problem of cost having been realized chloromethanes is simple in structure, safe, stable gas pressure, easy to operate demand.
