AI Technical Summary
Technical Problem
Existing waste heat recovery devices for gas generator sets have limited functionality, require large spaces for high-temperature flue gas treatment, and are highly complex, making them unsuitable for space-constrained locations.
Method used
The waste heat recovery and flue gas denitrification functions are integrated into a compact vertical structure. The design of the branch pipe and Venturi spray nozzle achieves uniform flue gas distribution and uniform mixing of reducing agent, reducing system complexity.
Benefits of technology
It greatly saves equipment installation space, simplifies system layout, improves heat exchange efficiency and denitrification effect, and is suitable for places with limited space.

Abstract
This utility model discloses a waste heat recovery device for a gas generator set, including a heat exchange shell arranged vertically. A bottom end cap and a connecting pipe are sequentially connected to the bottom of the heat exchange shell, and a spray nozzle, a top end cap, and an exhaust pipe are sequentially connected to the top of the heat exchange shell. A lower orifice plate is fixedly connected to the bottom of the heat exchange shell, and an upper orifice plate is fixedly connected to the top. Multiple evenly distributed branch pipes are installed between the upper and lower orifice plates. The spray nozzle consists of a tapering section, a throat section, and a expanding section connected sequentially from bottom to top. A reducing agent inlet pipe arranged horizontally is installed on the side wall of the tapering section, and an atomizing nozzle is installed at the outlet of the reducing agent inlet pipe. This utility model integrates the two core functions of waste heat recovery and flue gas denitrification into a compact vertical structure, greatly saving equipment installation space, simplifying system layout, reducing connecting pipe length, and reducing system complexity, making it particularly suitable for space-constrained locations.
