Abstract
The utility model provides an acid adding device for a membrane method denitration process. An acid preparation tank is arranged on a pipeline on which an acid adding tank is arranged; a water inlet of the acid adding tank is connected with an outlet pipe of the acid preparation tank; and an outlet pipe of the outlet pipe is connected with an inlet pipe of the acid adding tank. The pH value of a pretreatment unit operates stably by acid liquid prepared by the acid preparation tank; skip stop of a membrane method denitration device caused by fluctuation of the pH is reduced; secondary acid addition of the membrane method denitration device is cancelled; production cost is reduced; and economic benefit is created for enterprises.
Description
Technical field
The utility model relates to the out of stock technology of embrane method in the chlor-alkali production, implements to improve to adding sour device, promptly installs the complex acid jar additional, eliminates the parking phenomenon, and effect is splendid.
Background technology
Original design have only one sour jar, on one side complex acid add sour production operation, the wave phenomenon of pH value in the complex acid process, usually can occur on one side; Causing embrane method to remove nitre stops; Reason is that pretreatment unit is transferred the pH value surely, and salt solution directly gets into membrane filter unit, must cause the fluctuation of membrane filter unit pH; Even the jumping that causes device stops (pH value membrane filter unit band interlocking), and not only influence is produced and gone back damage equipment.Hua Tai company transforms the high purity acid header tank of potroom as the complex acid jar, has got rid of this production difficult problem.
Summary of the invention
The purpose of the utility model is: remove in the freezing poor salt made from earth containing a comparatively high percentage of sodium chloride water pot of nitre device in embrane method member is set, promptly lay over-pass, improve the cycle of treatment system, effect is scientific and reasonable, has reached original design requirement.
The purpose of the utility model is achieved in that sour device of adding of a kind of embrane method denitrating technique; Install complex acid jar 1 additional being installed with on the pipeline that adds acid jar 1; The water-in that adds acid jar 1 is connected with the outlet pipe of complex acid jar 1, and the outlet pipe that adds acid jar 2 is connected with the inlet pipe that adds sour pump 3; Wherein the inlet pipe of complex acid jar 1 connects hydrochloric acid operation 4, constitutes acid source; The outlet pipe that adds sour pump 3 goes to pre-treatment Unit 5.
This device forms with the header tank transformation, makes waste materials be able to sufficient utilization, has saved starting material, shows technical progress.
Description of drawings
The utility model combines accompanying drawing to do explanation
Accompanying drawing is the acid adding process schematic flow sheet of the out of stock technology of embrane method:
1-complex acid jar, 2-add acid jar among the figure, 3-adds sour pump, 4-hydrochloric acid operation, 5-and goes pre-treatment;
As shown in the figure: as header tank to be transformed into complex acid jar 1, acid concentration is transferred surely to 3-4%,, reduced fluctuation because of pH and caused that embrane method removes the jumping of nitre device and stop again through adding acid jars 2.
Embodiment
The utility model combines embodiment to do explanation
The pipe arrangement transformation of hydrochloric acid operation 4 is installed additional complex acid jar 1 in Hua Tai company, and complex acid jar acid 1 concentration is evenly prepared; Concentration is transferred surely to 3-4%, slowly puts into to add acid jars 2 again, removes nitre device pre-treatment 5 unitary acid sources as embrane method; Acid solution through 1 preparation of complex acid jar makes pre-treatment 5 unitary pH values stable; Guaranteed the smooth running of system, reduced fluctuation because of pH and caused that embrane method removes the jumping of nitre device and stop, and cancelled embrane method and removed the secondary of nitre device and add acid; Reduced production cost, for enterprise has created economic benefit.
