Abstract

The invention discloses a flue gas backflow preventing chimney for zinc oxide smelting, relates to the field of chimneys, and provides a flue gas backflow preventing chimney for zinc oxide smelting, which is exquisite in structure, good in using effect and good in backflow preventing effect. The flue gas backflow preventing chimney for zinc oxide smelting comprises a body, a gas inlet tube and a backflow preventing assembly, wherein the body sleeves the gas inlet tube; the top edge of the gas inlet tube is positioned in the middle of the body; the backflow preventing assembly comprises an annular bottom plate, an umbrella-cover-shaped baffle and a plurality of supporting rods; the inner edge of the bottom plate is fixedly connected to the outer wall of the gas inlet tube; the outer edge of the bottom plate is fixedly connected to the inner wall of the body; the baffle is fixedly connected to the inside of the body through the supporting rods and is positioned above the gas inlet tube; the bottom edge of the baffle extends to space between the gas inlet tube and the body; a water inlet and an overflow port are further formed in the body; the water inlet is higher than a top opening of the gas inlet tube; and the overflow port is higher than the bottom edge of the baffle and lower than the top opening of the gas inlet tube. The flue gas backflow preventing chimney for zinc oxide smelting has the features of exquisite structure, good using effect and good backflow preventing effect.

Description

technical field [0001] The invention relates to the field of chimneys, in particular to the improvement of the chimney for preventing flue gas backflow during zinc oxide smelting. Background technique [0002] At present, most of the chimneys used to discharge flue gas in zinc oxide smelting workshops have simple backflow prevention structures. Among them, a representative one, such as the "A Zinc Oxide Smelting Use anti-smoke backflow chimney", the document whose application number is "201320857269.2". In this case, several inclined angle baffles are added to the conical inner core to prevent backflow, but it still has the defects of single structure and poor anti-backflow effect. Contents of the invention [0003] Aiming at the above problems, the present invention proposes an anti-flue gas backflow chimney for zinc oxide smelting with exquisite structure, good use effect and good anti-backflow effect. [0004] The technical solution of the present invention is: compri...
