Abstract
The utility model particularly relates to a be used for waste acid recycling processing apparatus. Including spent acid groove and new acid tank, its characterized in that, the spent acid groove sets up with new acid tank relatively be equipped with the overflow mouth on the side relative with new acid tank of spent acid groove be equipped with the inlet on the side the that newly acid tank is relative with the spent acid groove, the inlet position is less than the overflow mouth, the inlet all is connected with sulphuric acid pipeline with the overflow mouth. This device improves present spent acid groove and new acid tank structure, and the sulphuric acid utilization ratio increases substantially in the system of messenger's chlorine press room, greatly reduced spent acid ER for emission rate, and reduction in production cost reduces the spent acid handling capacity simultaneously, lightens ambient pressure.
Description
Technical field
This utility model belongs to technical field of chemical, is specifically related to a kind of for waste acidity recovery process device。
Background technology
In sponge titanium smelting project, the electrolytic chlorine gas that magnesium eletrolysis produces needs to enter chlorine press system just can be delivered to chloride process reuse through processes such as pressurization, dry, sour separation。The concentrated sulphuric acid that working media is 92-98% used by the capital equipment chlorine press of this system, when the concentration of its working media concentrated sulphuric acid is less than 92%, for avoiding affecting chlorine press rotor fault rate, discharges to spent acid groove to store generally as spent acid and waits to focus on。
The concentrated sulphuric acid that chlorine press room uses is the concentrated sulphuric acid that the concentration that other factory's tank car is sent here is about about 98%, is driven into the new acid tank in chlorine press room through pump and stores stand-by。In actual production, due to the fact, that 1. equipment in system own, pipeline are dirtier, after causing running, intrasystem impurity major part enters in working media concentrated sulphuric acid；2. in the eo-acid that chemical plant tank car is sent here, impurity content is more；3. in bag filter outlet chlorine with the sublimate do not removed of part enter in the working media concentrated sulphuric acid of chlorine press room, the concentrated sulphuric acid solid impurity made in the short time in use can be cumulative, color is black, can not be continuing with, therefore enter spent acid groove only as spent acid and be neutralized process。A large amount of Waste Sulfuric Acid so will certainly be caused to produce, the concentrated sulphuric acid pot life also can shorten accordingly, increases spent acid treating capacity simultaneously, and then causes that production cost increase, environmental protection pressure are big。
Utility model content
Not enough for above-mentioned prior art, this utility model provides one to process device for waste acidity recovery, and this device can solve the problem that current spent acid processes Problems existing, reduces spent acid discharge capacity, saves production cost, reduces environmental protection pressure。
This utility model is achieved through the following technical solutions:
A kind of for waste acidity recovery process device, including spent acid groove and new acid tank, it is characterized in that, described spent acid groove and new acid tank are oppositely arranged, the side that described spent acid groove is relative with new acid tank is provided with overfall, being provided with inlet on the side that described new acid tank is relative with spent acid groove, described inlet position is lower than overfall, and described inlet is all connected with sulphuric acid conveyance conduit with overfall。
According to above-mentioned device, it is characterised in that described overfall and inlet and sulphuric acid conveyance conduit, each through Flange joint, are equipped with gasket seal in flange both sides。
According to above-mentioned device, it is characterised in that be provided with control valve on described sulphuric acid conveyance conduit。
According to above-mentioned device, it is characterised in that described overfall and spent acid groove distance from top are 1.2 meters。
Advantageous Effects of the present utility model, this utility model provides one to process device for waste acidity recovery, existing spent acid groove and new acid tank structure are improved by this device, sulphuric acid utilization rate in chlorine press chamber system is made to increase substantially, it is substantially reduced spent acid emission index, reduce production cost, reduce spent acid treating capacity simultaneously, alleviate ambient pressure。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
As shown in Figure 1, a kind of for waste acidity recovery process device, including the spent acid groove 1 being oppositely arranged and new acid tank 2, the side that spent acid groove is relative with new acid tank is provided with overfall 3, the overfall of preferred spent acid groove and spent acid groove distance from top are 1.2 meters, the side that new acid tank is relative with spent acid groove is provided with inlet 4, the inlet position of new acid tank is lower than the overfall of spent acid groove, the overfall of the inlet of new acid tank and spent acid groove is each through flange 5, 5 ' are connected with sulphuric acid conveyance conduit 6, it is equipped with gasket seal for sealing two flange both sides, sulphuric acid conveyance conduit material is 20# carbon steel, sulphuric acid conveyance conduit is provided with the control valve 7 that flange is installed, it is equipped with sealing gasket in the flange both sides being used for installing control valve, control valve to be used for controlling sulphuric acid break-make, the material controlling valve is cast steel liner PFA,
This utility model device is by existing spent acid groove side arranging an overfall and after pipeline utilizes gravitational settling remove impurity to process, supernatant overflow extremely new acid tank is for chlorine press, sulphuric acid utilization rate in chlorine press chamber system so can be made to increase substantially, it is substantially reduced spent acid emission index, reduce production cost, reduce spent acid treating capacity simultaneously, alleviate ambient pressure。
