Abstract
The utility model discloses a sample collection and detection device used for a bromination reaction kettle, which comprises a sampling tube communicated with an inner cavity of a reaction kettle body and a sampling valve, wherein the sampling tube is arranged at the top of the reaction kettle body and extends into materials held in the reaction kettle body, and a detection device is arranged at the top end of the sampling tube through the sampling valve. Since the detection device is arranged at the top end of the sampling tube through the sampling valve, during the sampling process, the materials can enter a detection chamber under such a condition that the internal pressure of the reaction kettle is positive or the ambient pressure is negative only by opening an emptying valve and the sampling valve, so that the purpose of collecting and detecting a sample can be achieved. The internal reaction conditions of the reaction kettle are not changed during the whole sample collection and detection process and the reaction can carry out normally without any influence, thereby ensuring the reaction quality and protecting the environment and the physical health of the operators against the hazards of dangerous gas leakage.
Description
Technical field
The utility model relates to sampler, is specifically related to a kind of sampling detecting device that is used for the bromination reaction still.
Background technology
In the Chemical Manufacture, often need repeatedly to take a sample in reactor in course of reaction, detection reaction still internal reaction carries out situation or product quality indicator situation.Traditional sampling detection mode is generally the sample valve sampling of opening reactor manhole or hand hole or reactor bottom, detects in the reactor outside then.This sampling detection mode not only troublesome poeration, hysteresis, and destroyed the molecular balance of system in the reactor, make the normal reaction process be interrupted, influence reaction process and product quality.Especially be corrosive, in the reaction that poisonous gas participates in, cause easily during sampling that hazardous gas effluxes synthetic grade of bromination, cause environmental pollution or bring harm the operator is healthy.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiency that prior art exists, provide a kind of take a sample convenient and safe, detect and do not influence the sampling detecting device that is used for the bromination reaction still of reactor internal reaction condition immediately.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The sampling detecting device that is used for the bromination reaction still, comprise the stopple coupon and the sample valve that are communicated with the inner chamber of described reaction kettle body, described stopple coupon is arranged on the top of described reaction kettle body and stretches in the material in the reaction kettle body, and the top of described stopple coupon is provided with pick-up unit by sample valve.
Wherein, described pick-up unit comprises transparent sensing chamber and atmospheric valve, and described sensing chamber is connected with the top of described stopple coupon by sample valve, and described atmospheric valve is arranged on the top of sensing chamber, and the intracavity bottom of described sensing chamber is provided with the instrument placing plate.
As a kind of improvement, the top of described sensing chamber inner chamber is provided with baffle plate.
Preferably, described instrument placing plate and baffle plate are orifice plate.
As further improvement, the bottom of described sensing chamber is provided with the setting-out pipe, and described setting-out pipe is provided with the setting-out valve.
As further improving, described atmospheric valve is connected with vacuum tube again.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is provided with pick-up unit on the top of stopple coupon by sample valve, only need open during sampling and enter sensing chamber under the condition that atmospheric valve and sample valve make material malleation or extraneous negative pressure in reactor and can finish sampling, and can the laying temperature meter in the sensing chamber, picnometer, combination electrode, detecting instruments such as acidometer, in the process of sampling, finish detection, instrument is placed in the transparent sensing chamber, can outside sensing chamber, read the detection data, sampling, detect whole process and can not change reactor internal reaction condition, can not influence the normal reaction process, therefore can guarantee reaction mass, also can not cause environmental pollution or harm operator healthy because of hazardous gas effluxes.
Instrument placing plate and baffle plate that the utility model is respectively equipped with orifice plate on the bottom and the top of sensing chamber's inner chamber, detecting instruments such as bottom instrument placing plate laying temperature meter, picnometer, the excessive damage detecting instrument of reacting kettle inner pressure when upper guard-plate prevents to take a sample.
The utility model is provided with the setting-out pipe in the bottom of sensing chamber, can access the partial material sample from the setting-out pipe and do synchronous detection or sundry item detection when sampling.
