Problems solved by technology
[0002] The sulfuric acid concentrated tail gas produced in industrial production needs to be treated before it can be discharged or reused, otherwise it will cause great harm to the natural environment. The treatment process for sulfuric acid concentrated tail gas in the prior art is: the second phase of sulfuric acid concentration in the nitration workshop The acid tail gas evaporated from the top of the acid still in the workshop only passes through the enamel pipeline connected to the evaporator, and then enters the condenser after being sprayed with acid water. load, most of the acid gas failed to condense in time, resulting in a high depth of acid water, and the acid tail gas pipeline is made of enamel pipeline. After the enamel pipeline is damaged, the repair period is long, which affects production. Therefore, people need a device for treating sulfuric acid concentrated tail gas To solve the problems existing in the existing technology

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see Figure 1-7 , the present invention provides technical solutions:
[0030] A device for treating concentrated sulfuric acid tail gas, comprising an acid still 101, a tower section 102 of the acid still, a transmission pipe fitting group 103, and a condenser. The transmission pipe fitting group 103 includes a PE steel skeleton pipeline and an FRPP pipeline, and the two ends of the FRPP pipeline are connected and installed with PE steel skeleton pipe...

The invention discloses a device for treating concentrated sulfuric acid tail gas, and relates to the technical field of sulfuric acid tail gas treatment. The device comprises PE steel skeleton pipelines and an FRPP pipeline, wherein the PE steel skeleton pipelines are connected and installed at the two ends of the FRPP pipeline. According to the invention, an original enamel pipeline is replaced with a combination of the PE steel skeleton pipelines and the FRPP pipeline, and after pipe fittings are damaged, a repair period is greatly shortened, and production continuity is effectively improved; a Pall ring packing layer and a teflon wire mesh demister are combined, so the teflon wire mesh demister can uniformly and efficiently intercept liquid drops in acidic tail gas, the acidic tail gas carrying the liquid drops is prevented from entering a condenser, the load of the condenser is prevented from being increased, and acid steam treatment efficiency is improved; and liquid drops which do not drop for a long time in the teflon wire mesh demister are intermittently purged, so the blockage degree of the teflon wire mesh demister can be effectively reduced, and the overall interception efficiency of the teflon wire mesh demister in a production process is improved.
