Embodiment Construction

[0009] In conjunction with accompanying drawing, provide embodiment of the present invention as follows, but the present invention is not limited to following embodiment:

[0010] Such as figure 1 As shown, a rectification experimental device includes a raw material tank 1 fixed on the frame, a tower top product tank 2, a tower kettle product tank 3, a tower kettle 4, a preheater 5, a sieve plate rectification tower 6, and a total condenser 7. Distillation experimental system composed of fractionator 8, feed pump 9 and multi-section stainless steel pipes. Wherein the preheater 5 and the tower kettle 3 are heated by a wet method. The sieve plate rectification tower 6 is fabricated by welding a stainless steel tower body. The total condenser 7 is a tube-and-tube heat exchanger, which is vertically fixed on the top of the tower by means of a flange connection. The transparent glass distillator 8 is welded together with the pipeline through a stainless steel flange. Feed pump ...

Abstract

The invention discloses an on-line rectification product concentration detecting device. On the structural basis of an existing device mainly comprising a raw material tank (1), a tower top product tank (2), a tower kettle product tank (3), a tower kettle (4), a pre-heater (5), a sieve plate rectifying tower (6), a total condenser (7), a fractionator (8), a charging pump (9) and a plurality of sections of stainless steel pipelines, a measuring device capable of detecting the concentration of a product on line is arranged near liquid inlets of the raw material tank (1), the tower top product tank (2) and the tower kettle product tank (3). The device is of a double-sleeve structure; an inner pipe (12) is lower than an outer pipe (11) and is vertically arranged; detected liquid flows into the inner pipe from bottom to top, overflows into a jacket of the inner pipe (12) and the outer pipe (11) and flows down into a corresponding tank body from the inner part of the bottom end of the jacket. Meanwhile, the liquid with a stable liquid surface is accumulated in the inner pipe (12), a hydrometer (10) floats in the inner pipe (12), and a temperature sensor (14) is arranged in a pipeline, into which the liquid flows, in front of the device; the temperature of the liquid can be synchronously measured, and the reading of the hydrometer can be corrected auxiliarily.

Description

technical field [0001] The invention belongs to the technical field of integrated chemical engineering principle experiment devices, and mainly relates to an online detection device for the concentration of rectification products. Background technique [0002] At present, the equipment of other manufacturers needs to take the raw material or product liquid into the container to detect its concentration, which is cumbersome to operate and the data lags behind. Contents of the invention [0003] In order to overcome the above drawbacks, the object of the present invention is to provide an online detection device for the concentration of rectification products. The problem of inconvenient on-line detection of rectification products is solved. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: it is mainly composed of raw material tank, tower top product tank, tower still product tank, tower still, preheater, sieve plate...
