The mixing equipment has the beneficial effects that the hydrogen peroxide is injected into the concentrated sulfuric acid by the micro-osmosis manner, and meanwhile the system is cooled by using a freezer dryer, and therefore the reaction temperature and the reaction concentration are controlled strictly, the occurrence degree of the reaction is effectively reduced; and the concentrated sulfuric acid and hydrogen peroxide are mixed under the condition of minimal reacting dose of hydrogen peroxide and concentrated sulfuric acid.
Description
Technical field
The utility model relates to a kind of mixing apparatus for the concentrated sulfuric acid and hydrogen peroxide.
Background technology
Expansible graphite has that cost is low, power consumption less, advantage such as the life-span is long, effective, it is widely used in industries such as oil, chemical industry, electric power, metallurgy, medicine, food, machinery.The Preparation of Expansible Graphite method mainly contains two kinds of chemical method and electrochemical processes, and the problem that chemical method exists is: the reaction temperature height, and the control difficulty is not utilized operation; Concentrated sulfuric acid use amount is big, the cost height; Follow-up washing step water consumption is big.Though electrochemical method has been avoided the use of strong acid and strong oxidizer, be subjected to the restriction of device and process conditions, be difficult to realize large-scale industrial production.
In order to overcome the shortcoming of above-mentioned prior art, can adopt the technology that oxidant and intercalator premix are mixed with crystalline flake graphite again.Adopt this technology can reduce the intercalator consumption significantly, and effectively reduce the content of dead sheet in the expansible graphite, improve allowance for expansion.But when adopting the concentrated sulfuric acid and hydrogen peroxide system, the heat release that very easily reacts of the concentrated sulfuric acid and hydrogen peroxide causes intercalated layered system to lose efficacy.In order to realize the mixing of the concentrated sulfuric acid and hydrogen peroxide system, and suppress to react to each other, need the injection mode, injection rate of strict hierarchy of control temperature and hydrogen peroxide etc.
The utility model content
The purpose of this utility model provides a kind of mixing apparatus for the concentrated sulfuric acid and hydrogen peroxide, so that a kind of equipment that can at utmost mix the concentrated sulfuric acid and hydrogen peroxide to be provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of mixing apparatus for the concentrated sulfuric acid and hydrogen peroxide, comprise reactor, be provided with paddle in the described reactor, described reactor lower end is provided with the blanking valve, described reactor is with chuck outward, be provided with cooling circulating water system in the described chuck, described reactor upper end is respectively equipped with that main liquid adds entrance and dispersion liquid adds entrance, and described dispersion liquid adds the built-in distributor of entrance coupled reaction still inside.
Further, described cooling circulating water system is connected with freeze drier.
Further, described built-in distributor comprises the annular arm, and described annular arm evenly is provided with some combs, and described comb lower end is provided with some micropores, preferred 8 ~ 12 of comb, preferred 5 ~ 25 of micropore.
Preferably, the inwall of described reactor and the material of paddle are enamel, and the material of described built-in distributor is the PPR(polypropylene), the PE(polyethylene), the PVC(polyvinyl chloride).
The beneficial effects of the utility model are: the mode by little infiltration is injected the concentrated sulfuric acid with hydrogen peroxide, adopts freeze drier that system is lowered the temperature simultaneously, and temperature and the reaction density of strict control reaction have effectively reduced the occurrence degree that reacts.Under the situation of hydrogen peroxide and concentrated sulfuric acid minimum reaction volume, finish mixing of hydrogen peroxide and the concentrated sulfuric acid.
