Description
Technical field
The utility model relates to polyvinyl chloride refining plant technical field, is that a kind of chemistry is containing tribute hydrochloric acid graphite copper packing refining plant.
Background technology
Produce in the process of polyvinyl chloride in calcium carbide route, run off because mercury bichloride easily causes mercury bichloride under the impact of the factors such as reaction heat, unstripped gas impurity.The mercury bichloride of this part loss causes salt acid pollution in hydrochloric acid along with air-flow is dissolved into.And mercury scarcity of raw material in the market, the price of mercury also goes up thereupon.
Summary of the invention
The utility model provides a kind of chemistry containing tribute hydrochloric acid graphite copper packing refining plant, has overcome the deficiency of above-mentioned prior art, and it can effectively solve calcium carbide route and produce part mercury bichloride in the process of polyvinyl chloride and be dissolved into the problem that causes salt acid pollution in hydrochloric acid.
The technical solution of the utility model is achieved like this: a kind of chemistry is containing tribute hydrochloric acid graphite copper packing refining plant, comprises the copper packing that simplified, graphite heat transfer block and purity are greater than 90%, there is ring platform inner side, lower end at cylindrical shell, in cylindrical shell, be sequentially installed with the graphite heat transfer block of at least three from top to bottom, the graphite heat transfer block of below is on ring platform, be fixed with in the upper end of cylindrical shell the flange that internal diameter is less than cylinder internal diameter, between the graphite heat transfer block of flange and the top, be installed with high-temperature resistant seal ring, between graphite heat transfer block and cylindrical shell, there is cavity, be fixed with respectively the steam inlet pipe and the drain pipe that communicate with cavity in the top and bottom of cylindrical shell, in each graphite heat transfer block, be distributed with vertically two axially extending bores that connect, copper packing is installed in axially extending bore, at the center-diameter of each graphite heat transfer block to being provided with heat transfer hole.
As preferably, the surrounding of above-mentioned each graphite heat transfer block is arranged with four heat transfer holes.
As preferably, above-mentioned ring platform is taper type wide at the top and narrow at the bottom, and the lower end of the graphite heat transfer block of below is positioned at ring platform.
As preferably, the upper outside of above-mentioned cylindrical shell is provided with the blow-down pipe being connected with cavity, is provided with the maintenance liquid discharge pipe being connected with cavity at the lower outside of cylindrical shell.
The utility model reasonable and compact in structure, easy to use, passing into steam at steam inlet pipe heats graphite heat transfer block, mercurous hydrochloric acid enters from the bottom of axially extending bore, mercury metal in mercurous hydrochloric acid and copper packing are adsorbed onto catalyst surface after replacing, then after steam indirect heating by mercury evaporation of metal out, not only realize and purify the object of mercurous hydrochloric acid, also collect mercury, improved the recycle value of mercury.
Brief description of the drawings
Fig. 1 is that the master of one of them axially extending bore of the utility model while copper packing not being installed looks sectional structure schematic diagram.
Coding in figure is respectively: 1 is cylindrical shell, and 2 is graphite heat transfer block, and 3 is copper packing, and 4 is ring platform, and 5 is flange, and 6 is cavity, and 7 is steam inlet pipe, and 8 is drain pipe, and 9 is axially extending bore, and 10 is heat transfer hole, and 11 is blow-down pipe, and 12 is maintenance liquid discharge pipe.
