Abstract
The invention discloses an anti-overflow device for a hydrochloric acid dropping tank. The top of the hydrochloric acid dropping tank is connected to a hydrochloric acid transfer tank in a lower position in a space through a feeding pipeline; and the bottom of the hydrochloric acid dropping tank is connected to a containing unit via a pipeline. Particularly, the lateral wall of the hydrochloric acid dropping tank in a certain height position is provided with an anti-overflow pipe in a connecting manner, and two ends of the anti-overflow pipe are communicated with the hydrochloric acid dropping tank and the hydrochloric acid transfer tank. By applying the anti-overflow device disclosed by the invention, the anti-overflow pipe is additionally arranged to the device in the prior art, the anti-overflow pipe can prevent the running phenomenon caused by overfull feeding, meanwhile, the air pressure inside the hydrochloric acid dropping tank is balanced, and an exhaust port does not need to be formed, so that potential accidents are eliminated from the source, pollution to the atmosphere caused by volatilizing and leaking of hydrochloric acid is completely eradicated, loss of materials is reduced, and the utilization rate of the materials is improved.
Description
Technical field
The present invention relates to a kind of Anti-overflow device, relate in particular to a kind of Anti-overflow device that drips tank for hydrochloric acid.
Background technology
In chemical products R-(+)-2-(4-hydroxyphenoxy) propionic acid production process, a step acid out operation is arranged, after synthetic reaction finishes, in reactant liquor, drip 30% hydrochloric acid, make the product crystallization.
In prior art, hydrochloric acid drips tank and is provided with top charging aperture, top drain, bottom dropping mouthful.The top charging aperture is for dripping the tank charging, and suck air (pneumostome) when the top drain drips for charging, keep the tank inside and outside air pressure balance.When this drips the tank feed operation, evacuation port has a large amount of acid gas discharges, and surrounding air is polluted.Also having a potential potential safety hazard, is exactly operating personnel when dripping tank and get the raw materials ready, once carelessness forget, will cause dripping tank and completely expect to overflow, cause the pollution of irremediable loss and environment.
Summary of the invention
The object of the invention is to propose a kind of Anti-overflow device that drips tank for hydrochloric acid.
Above-mentioned purpose of the present invention will be achieved by the following technical programs: the Anti-overflow device that drips tank for hydrochloric acid, described hydrochloric acid drips tank top and is connected the hydrochloric acid transfer tank that is positioned at the space low level by feed pipe, described hydrochloric acid drips pot bottom and connects the splendid attire unit by pipeline, it is characterized in that: described hydrochloric acid drips the sidewall of tank in the certain altitude position and is equipped with the anti-overflow pipe, and described anti-overflow pipe two ends are communicated with hydrochloric acid and drip tank and hydrochloric acid transfer tank.
Further, described certain altitude position and acidifying amount of hydrochloric acid dropping tank are complementary.
Further, described feed pipe is provided with the hydrochloric acid pump of getting the raw materials ready.
Apply Anti-overflow device of the present invention, its remarkable technique effect is: set up the anti-overflow pipe in prior-art devices, the anti-overflow pipe can prevent reinforced overfill and the race material phenomenon that produces, simultaneously balanced hydrochloric acid drips the air pressure in tank, without offering exhaust outlet, solved potential problem from source, stop the hydrochloric acid volatilization and revealed the pollution to atmosphere, reduce the loss of raw material, improved raw material availability.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation that drips the Anti-overflow device of tank for hydrochloric acid of the present invention.
The specific embodiment
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 1, a kind of Anti-overflow device that drips tank for hydrochloric acid, hydrochloric acid drips tank 1 and connects hydrochloric acid transfer tanks 3 by feed pipe 2, and feed pipe 2 is provided with the hydrochloric acid pump of getting the raw materials ready.Hydrochloric acid transfer tank 3 is for to hydrochloric acid, dripping the interior interpolation hydrochloric acid of tank 1, and hydrochloric acid drips tank 1 bottom and connects splendid attire unit 4 by pipeline, and splendid attire unit 4 carries out acidification reaction for the salt acid starting material that receives dropping.Especially, hydrochloric acid drips the sidewall of tank 1 in the certain altitude position and is equipped with anti-overflow pipe 5, and these anti-overflow pipe 5 two ends are communicated with hydrochloric acid and drip tank 1 and hydrochloric acid transfer tank 3, and balanced hydrochloric acid dropping tank 1 internal gas pressure, has the anti-overflow effect simultaneously.
In addition, anti-overflow pipe 5 is located at hydrochloric acid and is dripped tank 1 sidewall certain altitude position, this certain altitude position and hydrochloric acid drip acidifying amount of tank and are complementary, and while in hydrochloric acid drips tank, adding hydrochloric acid over an acidifying amount, unnecessary hydrochloric acid can flow to the hydrochloric acid transfer tank by the anti-overflow pipe.
Above-mentioned feed pipe is provided with the hydrochloric acid pump of getting the raw materials ready, and feeding is convenient and swift.During concrete enforcement, when dripping tank, hydrochloric acid need to get the raw materials ready, between hydrochloric acid dropping tank and splendid attire unit, pipeline is in closed state, open the hydrochloric acid pump of getting the raw materials ready, hydrochloric acid will enter hydrochloric acid by feed pipe and drip tank under hydrochloric acid is got the raw materials ready the driving of pump, the equal-volume gas that hydrochloric acid drips in tank will enter intermediate storage tank by the anti-overflow pipe, make two pressure tanks reach balance, when hydrochloric acid content reaches anti-overflow pipe nozzle position, unnecessary hydrochloric acid will be back to the hydrochloric acid transfer tank by the anti-overflow pipe, guarantee that hydrochloric acid drips hydrochloric acid in tank and can completely not expect, run material, hydrochloric acid drips tank in dripping the hydrochloric acid process, liquid level descends by anti-overflow pipe counterpressure, keep hydrochloric acid to drip tank in atmospheric pressure state, enhance productivity.
By above-mentioned character express, can find out, beneficial effect of the present invention: apply Anti-overflow device of the present invention, set up the anti-overflow pipe in prior art hydrochloric acid Dropping feeder, the anti-overflow pipe can prevent that reinforced overfill from the material phenomenon occurring to run, and simultaneously balanced hydrochloric acid drips the air pressure in tank, without offering exhaust outlet, solved potential problem from source, stop the hydrochloric acid volatilization and revealed the pollution to atmosphere, reduced the loss of raw material, improved raw material availability.
In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
Claims (3)
1. drip the Anti-overflow device of tank for hydrochloric acid, described hydrochloric acid drips tank top and is connected the hydrochloric acid transfer tank that is positioned at the space low level by feed pipe, described hydrochloric acid drips pot bottom and connects the splendid attire unit by pipeline, it is characterized in that: described hydrochloric acid drips the sidewall of tank in the certain altitude position and is equipped with the anti-overflow pipe, and described anti-overflow pipe two ends are communicated with hydrochloric acid and drip tank and hydrochloric acid transfer tank.
