Abstract
The invention provides a high-yield system for 105 acid. The high-yield system comprises a sieve plate tower, wherein a furnace gas inlet is formed in the lower end of the sieve plate tower, a furnace gas outlet is formed in the upper end of the sieve plate tower, an acid spraying device is arranged on a sieve plate at the uppermost end of the sieve plate tower, a flow velocity control valve is arranged on the acid spraying device, two pipelines are connected behind the flow velocity control valve, one pipeline is a 105 finished acid outlet pipeline and the other pipeline is connected with a cooler which is connected with an acid circulating tank, an acid circulating pump is arranged on the acid circulating tank which is directly connected with the bottom of the sieve plate tower, sulfuric acid sprayed from the acid spraying device and treated by the sieve plate tower is pumped into the acid circulating tank through the acid circulating pump, sulfuric acid is cooled through the cooler and then is conveyed into the acid spraying device again, and the circulation is repeated until the product achieves the requirement. The high-yield system for 105 acid has the advantages that the flow of sulfuric acid can be adjusted by controlling the flow velocity control valve, the problem that the sieve plate tower has less operation flexibility can be solved, and the maximum yield can be obtained by adjusting the ratio of acid feeding amount to the amount of gas entering the tower.
Description
Technical field
The invention belongs to gas washing in SA production field, refer to a kind of 105 sour high yield systems especially.
Background technology
High-concentration sulfuric acid is produced and is usually used packing tower, and this chemical industry equipment has larger turndown ratio, but its assimilated efficiency is lower, and it does not meet the requirement of extensive high yield, has also fettered further developing of plant produced.
Summary of the invention
For solving the problem, the invention provides.
Concrete solution is: a kind of 105 sour high yield systems, comprise sieve-tray tower, sieve-tray tower lower end is furnace gas import upper end is furnace gas export, sieve-tray tower topmost sieve plate are provided with sour shower device, acid shower device is provided with flow control valve, two pipelines are connected after flow control valve, article one, be that 105 finished acids go out acid tube road, another connection water cooler, water cooler connects sour circulation groove, acid circulation groove is provided with acid circulating pump, acid circulation groove directly connects bottom sieve-tray tower, the sulfuric acid of acid circulating pump by sour shower device ejection and through sieve-tray tower process is pumped in sour circulation groove, again sour shower device is being sent into after supercooler cooling, recirculation is until product reaches requirement.
Further, described flow control valve is Stainless Steel Ball Valve.
The invention has the advantages that, the flow of sulfuric acid can be regulated by coutroi velocity control valve, solve the problem that sieve-tray tower turndown ratio is little, by regulating the ratio of upper sour Liang Yuruta road tolerance, can maximum production be obtained.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein:
1. sieve-tray tower 2. sour shower device 3. flow control valve 4. acid circulating pump
5. sour circulation groove 6. water cooler
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, a kind of 105 sour high yield systems, comprise sieve-tray tower 1, sieve-tray tower 1 lower end is furnace gas import upper end is furnace gas export, sieve-tray tower 1 topmost sieve plate are provided with sour shower device 2, acid shower device 2 is provided with flow control valve 3, two pipelines are connected after flow control valve 3, article one, be that 105 finished acids go out acid tube road, another connection water cooler 6, water cooler 6 connects sour circulation groove 5, acid circulation groove 5 is provided with acid circulating pump 4, acid circulation groove 5 directly connects bottom sieve-tray tower 1, sour shower device 2 sprays by acid circulating pump 4 and sulfuric acid through sieve-tray tower process is pumped in sour circulation groove 5, through supercooler cold 6 but after again send into sour shower device 2, recirculation is until product reaches requirement.
The invention has the advantages that, the flow of sulfuric acid can be regulated by coutroi velocity control valve, solve the problem that sieve-tray tower turndown ratio is little, by regulating the ratio of upper sour Liang Yuruta road tolerance, can maximum production be obtained.
