Abstract
The invention relates to a dredging device (20) which comprises a crystallization tank (13), wherein the crystallization tank (13) is connected to a centrifuge (6) through a pipeline (5); a first valve (4) is arranged in the pipeline (5); and at least one dredging pipe (7, 12) is arrange between the first valve (4) and the crystallization tank (13). By using the dredging device, under the conditions of constant pressure and different external temperatures, the unsmooth flow problem of the pipeline between the crystallization tank and the product centrifuge, which is caused by the crystallization of the mother liquor of the product, is solved.
Description
Technical field
The present invention relates to a kind of mediation equipment, particularly make the unobstructed mobile equipment of solution in the connecting pipe of process units.
Background technology
In the production process of chemicals, the formation of a lot of products is carried out in crystallization tank, and its process is that the solution of high concentration or supersaturated solution are slowly cooled off, and makes solute slowly form the process that crystal is separated out.Crystallization process generally need reduce the temperature of solution, so crystallizer is typically provided with heat-exchange device, simultaneously also with mechanical agitation or pumping installations, so that flow of solution.Nucleus in the solution can be suspended in the solution, thereby obtain crystal of uniform size.Mostly adopt cooling crystallizing equipment in the actual production,, make solution enter the supersaturation district and carry out crystallization, and constantly cooling, have certain supersaturation concentration and educate crystalline substance to keep solution by reducing temperature.
In product crystallisation by cooling process, often the crystalline product in the crystallization tank is in crystallization process, because the gravity effect is deposited on the bottom of crystallization tank and the outlet bottom the crystallization tank is stopped up, cause solution to flow into voluntarily in the centrifuge, hinder solute and solvent in the solution to be separated from each other, cause production not smooth thus, accident results in blockage.
Summary of the invention
The invention provides a kind of technical scheme, it can eliminate the clogging of the crystallization tank and the product centrifuge interface channel of crystalline product in the production process for this reason, and interface channel is unimpeded between the maintenance process units.
The present invention relates under normal pressure that crystalline product flows automatically to the equipment that the product centrifuge carries out the product dehydration in the crystallization tank.Problem to be solved provides a kind of can effectively the solution under different ambient temperatures, and connecting pipe is because of the obstructed problem of product mother liquid crystallization between crystallization tank and the product centrifuge.Its technical scheme is by insert high-pressure water pipeline and/or jet chimney on the connecting pipe between crystallization tank and the product centrifuge, pass through the control of different valves on each pipeline again, be implemented under normal temperature or the cryogenic conditions, use water under high pressure and/or steam to get through connecting pipe between crystallization tank and the product centrifuge respectively, realize that smoothly crystalline product flow to the technological process that centrifuge carries out the product dehydration voluntarily in the crystallization tank.
At a kind of mediation equipment provided by the invention, it comprises crystallization tank, and described crystallization tank links to each other with centrifuge by pipeline.In pipeline, be provided with first valve, between described first valve and crystallization tank, be provided with at least one dredging pipe.
According to a kind of mediation equipment provided by the invention, it is included in the pipeline, is provided with second valve between described dredging pipe and crystallization tank.
According to a kind of mediation equipment provided by the invention, it comprises that described dredging pipe is high-pressure water pipe or steam pipe, is provided with the 3rd valve and first measurement mechanism in described high-pressure water pipe, is provided with the 4th valve and second measurement mechanism in described steam pipe.
According to a kind of mediation equipment provided by the invention, it comprises that described high-pressure water pipe and steam pipe space are provided with.
According to a kind of mediation equipment provided by the invention, it comprises that described first measurement mechanism and second measurement mechanism are flowmeters.
The invention solves under the condition of normal pressure and different ambient temperatures, connecting pipe is because of the obstructed mobile problem of product mother liquid crystallization between crystallization tank and the product centrifuge.
Description of drawings
Fig. 1 is a kind of embodiment schematic diagram of dredging equipment provided by the invention.
The specific embodiment
As shown in Figure 1, in a kind of mediation equipment 20 embodiment provided by the invention, it comprises crystallization tank 13, and described crystallization tank 13 links to each other with centrifuge 6 by pipeline 5.In pipeline 5, be provided with first valve 4 and second valve 3.Between described first valve 4 and second valve 3, be provided with the high-pressure water pipe 7 and the steam pipe 12 of space.
In provided by the invention a kind of embodiment that dredges equipment 20 shown in Figure 1, dredging pipe 7,12 is respectively high-pressure water pipe 7 and steam pipe 12.In described high-pressure water pipe 7, be provided with the 3rd valve 8 and first measurement mechanism 9.In described steam pipe 12, be provided with the 4th valve 11 and second measurement mechanism 10.
In a kind of embodiment that dredges equipment 20 provided by the invention, described first measurement mechanism 9 and second measurement mechanism 10 are flowmeters.
The course of work of a kind of embodiment that dredges equipment 20 provided by the invention is as described below:
In normal productive process, the 4th valve 11 on the steam pipe 12 and the 3rd valve 8 on the high-pressure water pipe 7 are in closed condition.When the work mother liquor passed through motor 2 driving stirring cooling devices 1 in crystallization tank 13, the work mother liquor is cooling gradually in crystallization tank 13, the crystallization of realization product.At this moment, under the effect of gravity, the partially crystallizable body is deposited to the bottom of crystallization tank 13, when stopping up the connecting pipe 5 between crystallization tank and the centrifuge, in the different temperatures scope, respectively by the 3rd valve 8 on the unlatching high-pressure water pipe 7 and/or the 4th valve 11 on the steam pipe 12, close first valve 4, make water under high pressure and steam flow crystallization tank 13, crystallization tank 13 that conducting is stopped up and the connecting pipe 5 between the centrifuge 6 are opened first valve 4 subsequently, realize that crystalline product flow in the centrifuge 6 by connecting pipe 5 smoothly voluntarily in the crystallization tank 13, realize the Separation of Solid and Liquid of product, crystallization is shaped.
The foregoing description only is that a kind of mediation equipment provided by the invention is described, and is not to limit.Content that the present invention is claimed and scope are documented in claims of the present invention.
