Description
Technical field
The utility model relates to the device that in tar, liquid water content detects, and is specifically related to a kind of pick-up unit of coal tar liquid water content.
Background technology
Coal tar is a kind of product liquid that obtains in dry distillation of coal process, and certified more than 400 kinds that reach of the compound that comprises are a kind of very important industrial chemicals.The liquid water content of coal tar must strict be controlled, and in the national standard of coai-tar product, liquid water content is put into as the important technology index, in national standard in No. 1 coal tar moisture be not more than that in 3.0%, No. 2 coal tar, moisture is not more than 4.0%.Therefore, in coal tar, the mensuration of moisture is most important to the evaluation of coai-tar product.
In existing coal tar, the method for determination of moisture roughly has two kinds, and a kind of is chemical method, and a kind of is physical method.The reaction of chemical method general using chemical substance and water, the content of the gas that generates by mensuration calculates moisture; Physical method is generally to utilize the different boiling point of composition in coal tar, carries out fractionation, and other organic principles are lower relatively for the boiling point of water, distillates at first, so the control of the temperature in physical method is most important.The relative physical method of chemical method is comparatively complicated, and can not guarantee that reaction is enough abundant, so physical method is comparatively general in the Water content determination the inside application of coal tar.But in the prior art, the device of physical method fractionation moisture can't detect in real time to the cut temperature mostly, the constant temperature scope that more difficult confirmation heating keeps.In addition, most determinator is with the condenser pipe positioned vertical, although constantly make improvement, but still can't thoroughly solve cool solidifying moisture descends and conflicting and collision that moisture vapor rises and produces, cause water droplet to break splashing bend pipe flowing back to distilling flask, the error of Water content determination result in coal tar is increased.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of determination of moisture device in existing coal tar, and provide a kind of pick-up unit of improved coal tar moisture, this device can make the mensuration process of coal tar moisture convenient, rigorous, and the measurement result error is less.
Scheme of the present utility model is achieved by the following technical measures:
A kind of pick-up unit of coal tar liquid water content comprises flask, condenser pipe, adapter tube, bend pipe, drainage bend pipe, measures pipe.Wherein flask used adopts the twoport flask, the vertical openings end is communicated with a bend pipe that is provided with the built-in temperature meter, bend pipe is communicated with condenser pipe, the condenser pipe transverse pitch is settled, the endpiece position is on the low side, endpiece is communicated with adapter tube, and adapter tube lower end outlet is inserted twoport and measured in the work solvent of pipe, and the side mouth of measuring pipe is communicated with the side opening of flask by the drainage bend pipe.
Be provided with the built-in temperature meter in the bend pipe that is communicated with the flask vertical openings in the utility model device, thermometer is located in the inwall of bend pipe, designs for integral type with elbow internal wall, is the part of elbow internal wall, temperature that can the real time measure cut is convenient to control heating-up temperature.
Condenser pipe transverse pitch in the utility model device is installed, and cut and condensed fluid uniflux have thoroughly solved the collision problem between cut gas and condensed fluid; The outlet of adapter tube lower end is inserted in the hydraulic fluid of measuring in pipe, both sealed and measured pipe, the cut of the outflow by the flask side pipe can't be leaked in atmosphere, also increased the duration of contact of cut and working fluid, make the larger moisture of density that the sufficient settling time be arranged; Twoport is measured the downward-sloping design of side mouth pipe of pipe, make the upper strata working fluid be convenient to overflow back distilling flask, both replenished the work solvent in the flask, guarantee again to dissolve in the upper strata not in time the cut that flask side mouth flows out of passing through of precipitation slip back distilling flask and continue to distill; In the drainage bend pipe, remaining moisture is subject to the Action of Gravity Field that washes away and tilt of skimmer circuit, also can again flow to distilling flask, until there is no moisture in cut.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
