Abstract
The utility model relates to a feeding pipeline system of a chemical reaction device. A feeding pipeline comprises a pipeline for communicating an upstream process with a downstream process and a valve arranged on the pipeline. The pipeline is provided with a metering pump. The metering pump is fluid conveying equipment with conveying capability. The pipeline system has no requirements on pressure inside reactors of the upstream and downstream processes. The pipeline has strong universality. The output power and the conveying capability of the metering pump can be conveniently and accurately adjusted. Therefore, the feeding pipeline is convenient to use, can control material flow in the pipeline highly and accurately and can be widely applied in the fields of chemical production or sewage treatment and the like.
Description
Technical field
The utility model relates to the feeding pipe system of chemical reaction equipment.
Background technology
In the existing Chemical Manufacture, carry reaction mass by pipeline between the reactor of upstream and downstream operation, the size of mass flow relies on the flowmeter on the pipeline to observe, control the size that the pressure differential in the reactor of upstream and downstream is regulated mass flow then, when needing to accelerate mass transport, strengthen pressure in the upstream reactor, reduce the pressure in the downstream reactor, material enters the reactor of lower procedure because of the pressure reduction of pipe ends flows automatically; Otherwise the flow that will reduce material only need reduce the pressure in the upstream reactor, the pressure in the rising downstream reactor.
The precision that but such setting at first is a flow to be adjusted is too low, also just causes the instability of mass flow, and material adds too fast or crosses all can influence technic index slowly, cause product quality low in addition cause sudden and violent poly-, initiating failure and security incident; Simultaneously, because of mass transport is to depend on pressure differential in the reactor of upstream and downstream, and the pressure of reaction environment itself is the important process control index of chemical reaction, the pressure of adjusting in the reactor in order to regulate flow also can bring adverse effect to reaction speed and product quality, and the limitation that just such pipeline uses is big.
Summary of the invention
The purpose of this utility model just provides a kind of easy to use and can accurately adjust the feeding pipe of the chemical reactor of mass flow.
The scheme that adopts is exactly a kind of feeding pipe, comprises the pipeline that is communicated with the upstream and downstream operation, and is arranged on the valve on the pipeline, and is furnished with measuring pump on the pipeline.
In the technique scheme, measuring pump is the conveying equipment for fluid substances that itself has conveying capacity, such pipe-line system has no requirement to the pressure in the reactor of upstream and downstream operation, the highly versatile of pipeline, and the power output of measuring pump and conveying capacity can accurately be adjusted easily, so the utility model is easy to use, and can control mass flow in the pipeline accurately, such feeding pipe can be widely used in fields such as Chemical Manufacture or sewage disposal.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
A kind of pipe-line system of giving reactor 5 chargings as shown in Figure 1 comprises pipeline 3, and the charging aperture of pipeline 3 connects the discharging mouth of pipe of the container 1 of upstream process, and the outlet of pipeline 3 is connected on the charging aperture of downstream reactor 5; Valve 4,4` are set, so that the break-make of control piper on the pipeline 3; Also be provided with measuring pump 7 on the pipeline 3, measuring pump 7 can be plunger type metering pump or screw pump, and just conveying capacity adjustable fluid delivery pump both had been convenient to the conveying of fluid, and cost is also lower; Valve 4,4` preferably lay respectively at the upstream and downstream position that is positioned at measuring pump 7 on the pipeline 3, when measuring pump 7 damages or needs repairing, and can be easily by pipeline maintenance or replacing measuring pump 7.
Because the conveying equipment for fluid substances that measuring pump 7 has conveying capacity itself, such pipe-line system has no requirement to the pressure in the reactor 1,5 of upstream and downstream operation, the highly versatile of pipe-line system, mass transport advantage for viscosity height, easy caking is especially obvious, and the power output of measuring pump and conveying capacity can accurately be adjusted, so the utility model can be controlled the mass flow in the pipeline accurately, such feeding pipe can be widely used in fields such as Chemical Manufacture or sewage disposal.
