Abstract
Once the accident of the condensation acid occurs in an expansion joint of the smoke pipeline in the acid production device such as sulfur producing acid, sulfurous iron ore producing acid and smelt metal tail gas producing acid, the condensation acid is stockpiled at the bottom of the expansion joint and can not leak and cause rusty and damage at the bottom of the expansion joint. An improved structure of flue gas pipeline expansion joint is provided with a discharge hole at the bottom of the expansion joint. A match pipe and a valve of erosion resistant is connected with the outlet of the discharge hole, thereby discharging the condensation acid and preventing the expansion joint from corrosion and injury.
Description
Technical field
The utility model relates to sulphur-burning sulphuric acid plant, pyrite-based sulfuric acid production device, smelting exhaust sulphuric acid plant, or the structure manufacturing of fume pipe expansion joint in other sulphuric acid plant.Especially the improvement structure that refers to a kind of relieving haperacidity fume pipe expansion joint.
Background technique
Fume pipe in sulphur-burning sulphuric acid plant, pyrite-based sulfuric acid production device, smelting gas sulphuric acid plant or other sulphuric acid plant all will be provided with expansion joint to eliminate the stress that is caused by the temperature variation reason at present.When fume pipe was arranged horizontally, expansion joint was vertical the installation.In case condensation acid accident takes place, and condensation acid will accumulate in the bottom of expansion joint and can't release, cause expansion joint bottom corrosion and damage accident.(seeing accompanying drawing 1,2)
Summary of the invention
The purpose of this utility model is to provide a kind of improved relieving haperacidity fume pipe expansion joint, bores an escape orifice in expansion joint bottom, just when producing condensation, can release, and makes the expansion joint bottom can corrosion and damage.
For reaching above-mentioned purpose, the improvement structure of relieving haperacidity fume pipe expansion joint of the present utility model, its key technology is to bore an escape orifice in the expansion joint bottom, and in the escape orifice outlet port, connect one and have etch-proof pipe arrangement and valve, so that discharging condensation acid can prevent effectively that the condensation acid etching of expansion joint bottom from damaging.
