Background

The flue gas condenser is a treatment device for cooling high-temperature flue gas, and is widely applied to various industries such as power generation, food, environmental protection and the like. The temperature of the discharged flue gas is reduced mainly by circulating cooling water, so that conditions are created for subsequent waste reduction, and the recovered heat can be used for other purposes, so that the energy is recycled. At present, the structural form of the flue gas condenser is many, but most of the flue gas condensers adopt a condensation pipe with a bent pipe structure, and the flue gas condensers are not easy to process and assemble. The invention provides a flue gas condenser which has a simple structure and is suitable for being combined and used in a large flue.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution:

a flue gas condenser comprises a main body 10 of frame construction. A plurality of condensation pipes 12 are vertically arranged in the main body 10, and gaps for smoke to pass through are formed among the condensation pipes 12. The lower portion of the main body 10 is provided with a hollow inlet chamber 14 and a hollow outlet chamber 16, and the upper portion of the main body 10 is provided with a hollow catchment chamber 18. The water inlet cavity 14 is communicated with a water inlet pipe (not shown), the water outlet cavity 16 is communicated with a water outlet pipe (not shown), and the water collecting cavity 18 is closed. One end of all the condensation pipes 12 is communicated with the water converging cavity 18, the other end of part of the condensation pipes 12 is communicated with the water inlet cavity 14, and the other end of the other part of the condensation pipes 12 is communicated with the water outlet cavity 16. In use, cooling water enters the inlet chamber 14 from the inlet pipe, then enters the water collecting chamber 18 from a part of the condensation pipes 12, and enters another part of the condensation pipes 12 from the water collecting chamber 18, finally reaches the outlet chamber 16, and is discharged through the drain pipe. In the period, the flue gas passes through the condensing pipes 12 to realize heat exchange.

The water collection chamber 18, the water inlet chamber 14 and the water outlet chamber 16 each include a partition 20, and the partition 20 is provided with a plurality of through holes 22 for the condenser tubes 12 to pass through. The inlet chamber 14, outlet chamber 16 and catchment chamber 18 further include an arcuate cover plate (not shown) and two end plates (not shown), the cover plate, the two end plates and a partition plate 20 together forming a closed chamber, i.e., the corresponding catchment chamber 18, inlet chamber 14 and outlet chamber 16. Through the arc-shaped cavity structure, the resistance of cooling water can be effectively reduced

The cover plates of the water inlet cavity 14 and the water outlet cavity 16 are respectively provided with a water valve 24 communicated with the water inlet cavity 14 or the water outlet cavity 16, the water valves 24 are communicated with a water inlet pipe or a water outlet pipe, and the water valves 24 are connected with the flue gas condenser through flanges, so that the assembly, disassembly and maintenance are convenient.

Further, a plurality of fixing rods 26 for fixing the condensation duct 12 are provided to be inclined on the main body 10 to prevent the condensation duct 12 from being deformed.
