The utility model discloses a sulfuric acid feeding device in acidification reaction. The sulfuric acid feeding device comprises a feeding control valve and a feeding distributor, wherein the feeding control valve is arranged on a sulfuric acid feed pipe, the feeding control valve is connected with the feeding distributor which comprises a strip-shaped body and a plurality of discharge holes that are formed in the strip-shaped body respectively uniformly. The sulfuric acid feeding device can adjust the feeding flow rate of sulfuric acid, so that the usage amount of sulfuric acid can be controlled, the waste due to excessive acid feeding or difficult treatment of acid water is avoided, the situation that the acidification is incomplete due to insufficient acid feeding cannot occur, and the situation that acidified oil is deep in color and low in yield due to carbonization can be prevented. Furthermore, toxic gases such as sulfuric oxide cannot be produced, so that the working environment can be improved, and atmospheric pollution can be prevented.
Description
Technical field
The utility model relates to a kind of acidification reaction device, in particular the sulfuric acid feeding device in a kind of acidification reaction.
Background technology
Soap stock is produced in the technique of acidification oil, substantially all makes with sulfuric acid and soap stock reaction, but all exists the acidification oil color of producing dark, and wherein contain the phenomenon of certain impurity.The main cause that causes this phenomenon be exactly use sulfuric acid be the concentrated sulfuric acid, and the concentrated sulfuric acid has strong dehydration property and oxidisability, in the time the concentrated sulfuric acid directly being pumped in acidifying still by conventional method and soap stock mixes, there will be localized rich sulfuric acid concentration high, cannot disperse in time, cause soap stock by concentrated sulfuric acid carbonization, make acidification oil color dark, had a strong impact on quality and the use of acidification oil; Also can follow generation oxidation reaction simultaneously, produce the materials such as sulfur dioxide, and sulfur dioxide be a kind of gas with certain toxicity, still forms the main component of acid rain, has so just caused air pollution and potential safety hazard.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the feeding device of the sulfuric acid in a kind of acidification reaction is provided, and improves the quality of acidification oil.
The utility model is achieved through the following technical solutions, the utility model comprises the charging control valve and the feed distributor that are arranged on sulfuric acid feed pipe, described charging control valve is connected with feed distributor, described feed distributor comprises bar shaped body and multiple discharge opening, and described multiple discharge openings are uniformly respectively on bar shaped body.
Described charging control valve comprises the first ball valve, pneumatic control valve, flowmeter, the second ball valve and the 3rd ball valve, described the first ball valve, pneumatic control valve, flowmeter and the second ball valve are in parallel with the 3rd ball valve again after connecting successively, and the outlet of the second ball valve is connected with the import of feed distributor.
A kind of acidizing device that uses the sulfuric acid feeding device in described acidification reaction, comprise acidifying still, sulfuric acid feed pipe and soap stock feed pipe, described sulfuric acid feed pipe and soap stock feed pipe are arranged at respectively on acidifying still, and sulfuric acid feed pipe is connected with feed distributor, in acidifying still, are provided with agitator.
The utility model has the following advantages compared to existing technology: the utility model can regulate the feed rate of sulfuric acid, so just can control sour consumption, both there will not be acid adding too much and the waste and the unmanageable situation of sour water that produce, also there will not be and add that hypoacidity and the incomplete situation of acidifying, avoided acidification oil to occur the dark and low situation of recovery rate of color because of carbonization.Nor can produce the toxic gases such as sulfur dioxide, and improve like this working environment, can not cause atmosphere pollution yet.
Brief description of the drawings

Fig. 2 is the structural representation of sulfuric acid feeding device.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under taking technical solutions of the utility model as prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, the present embodiment comprises acidifying still 1, sulfuric acid feed pipe 2, soap stock feed pipe 3 and feed distributor 4, described sulfuric acid feed pipe 2 and soap stock feed pipe 3 are arranged at respectively on acidifying still 1, sulfuric acid feed pipe 2 is connected with feed distributor 4, in acidifying still 1, be provided with agitator 11, charging control valve is set on sulfuric acid feed pipe 2, described charging control valve is connected with feed distributor 4, described feed distributor 4 comprises bar shaped body 41 and multiple discharge opening 42, and described multiple discharge openings 42 are uniformly respectively on bar shaped body 41.
Described charging control valve comprises the first ball valve 5, pneumatic control valve 6, flowmeter 7, the second ball valve 8 and the 3rd ball valve 9, described the first ball valve 5, pneumatic control valve 6, flowmeter 7 and the second ball valve 8 are in parallel with the 3rd ball valve 9 again after connecting successively, and the outlet of the second ball valve 8 is connected with the import of feed distributor 4.
Before feed distributor 4, add a charging control valve, by charging control valve and feed distributor 4, in adding the concentrated sulfuric acid, can make it be distributed in the zones of different of acidifying still 1, and can control the speed that adds of sulfuric acid, can make like this concentrated sulfuric acid contact with soap stock more fully, add the speed of fast response, can not cause localized rich sulfuric acid that carbonization and oxidation reaction too much occur simultaneously yet, the color relation of the acidification oil of producing so can not be deepened, nor can produce the toxic gases such as sulfur dioxide, improve like this working environment, can not cause atmosphere pollution yet.
Soap stock through heating enters acidifying still 1 from soap stock feed pipe 3, and sulfuric acid enters acidifying still 1 by sulfuric acid feed pipe 2, the inlet amount of sulfuric acid is controlled by flowmeter 7 and pneumatic control valve 6, sulfuric acid feed pipe 2 connects feed distributor 4, penetrated to all directions by each discharge opening 42 at the interior sulfuric acid of feed distributor 4, sulfuric acid is just fully disperseed like this, then stirs through agitator 11, and the concentrated sulfuric acid just there will not be to be assembled somewhere and made the situation of acidification oil carbonization.System can also regulate the feed rate of sulfuric acid, so just can control sour consumption, both there will not be acid adding too much and the waste and the unmanageable situation of sour water that produce, also there will not be and add that hypoacidity and the incomplete situation of acidifying, and avoided acidification oil to occur the dark and low situation of recovery rate of color because of carbonization.
