Abstract
The invention relates to an apparatus for purifying organic matters in waste sulfuric acid. The apparatus for purifying organic matters in waste sulfuric acid comprises a gas source, a gas boosting device, a gas heating device, a gas distillation tube and a gas-liquid mixer, the gas source is connected with the gas boosting device through the gas distillation tube, the gas boosting device is connected with the gas heating device through the gas distillation tube, the gas heating device is connected with the gas-liquid mixer through the gas distillation tube, a siphon is arranged in the gas-liquid mixer, a siphon fixation frame is arranged at two sides of the siphon, a gas chamber is arranged in the siphon fixation frame, a gas nozzle is arranged at one end of the gas-liquid mixer, and a catalyst carrier is arranged in the gas nozzle. The apparatus has a simple structure, can be reliably used, can be used independently or together with other equipment, organically combines gas stripping and oxidation which are two means for removing waste sulfuric acid, and can thoroughly remove the organic matters in the waste sulfuric acid.
Description
Technical field
The present invention relates to organic refining plant in a kind of sulfur waste acid.
Background technology
At present, sulfuric acid is modal a kind of chemical in the chemical industry, it is widely used in many industrial sectors most, we can say, the sulphuric acid output of a country indicates the industrial level of a country, the sulphuric acid output of China is nearly 6,000 ten thousand tons/year at present, rank first in the world, illustrate that the China recent years industrial development is very fast, sulfuric acid in use roughly is divided into three kinds of situations: or be fixed in the product as the integral part of product, or change the undesirable by product of people into, or eject from production system with sulfur waste acid form.Sulfuric acid can be used for etching industry, electroplating industry, acid in the battery, chemical fertilizer, explosive, agricultural chemicals, dyestuff, refining of petroleum, siccative, purifying agent, and be used for reagent of chemosynthesis etc., China is annual at present must dispose more than 2,000 ten thousand tons of sulfuric acid in containing acid waste liquid, wherein contain organism spent acid amount every year all at millions of tons, various sulfur waste acid can't be fully utilized fully, if with its direct discharging, not only lost ample resources, and meeting serious environment pollution, development along with China's recycling economy, how industrial waste sulfuric acid is fully recycled, become urgent problem.
Summary of the invention
The present invention provides a kind of simple in structure in order to remedy the defective of prior art, organic refining plant in the convenient sulfur waste acid of using.
The present invention is achieved through the following technical solutions:
Organic refining plant in a kind of sulfur waste acid, comprise that source of the gas, gas pressurized device, gas-heating apparatus, gas heat up in a steamer pipe and gas liquid mixer, described source of the gas heats up in a steamer pipe by gas and is connected with gas pressurized device, gas pressurized device heats up in a steamer pipe by gas and is connected with gas-heating apparatus, gas-heating apparatus heats up in a steamer pipe by gas and is connected with gas liquid mixer, in the described gas liquid mixer siphon pipe is housed, the siphon pipe anchor is equipped with in the siphon pipe both sides, in the siphon pipe anchor gas compartment is housed, gas liquid mixer one end is equipped with gas tip, and support of the catalyst is housed in the gas tip.
The invention has the beneficial effects as follows: simple in structure, use reliable, this equipment can independently use or be used with other equipment, this device is carried gas with the useless vitriolic means of these two kinds removals of oxidation and is combined, make in the sulfur waste acid organic removal more thorough, the application of gas liquid mixer can more can fully contact sulfur waste acid with the ozone-containing air of heat, Organic Materials of Spent acid can be proposed by more effective gas or generated carbonic acid gas and thoroughly removed by abundant oxidation, gas carries that acid has stirring action to sulfur waste simultaneously in the process, further increase gas and put forward effect, improved purification efficiency, this device has concurrently useless vitriolic inspissated, makes containing organic useless vitriolic purifying regeneration process more economical.
