Anti-blocking coal economizer structure

Abstract

The invention discloses an anti-blocking coal economizer structure. The anti-blocking coal economizer structure comprises heat conduction pipes, a water inlet, a water outlet, a dirt discharge port, spraying pipes, rotary joints, a movable cleaning bin, a distribution box, an inspection door and a console, the multiple heat conduction pipes are coiled to form a cuboid structure, the water inlet isformed in the upper right corner of the top face of the heat conduction pipes, the water outlet is formed below the front end of the left side of the heat conduction pipes, and the dirt discharge port is horizontally arranged at the right side of the water outlet. The tails of the spraying pipes are fixedly connected to the front face of the heat conduction pipes, the rotary joints are in boltedconnection with the tops of the spraying pipes, and the movable cleaning bin is fixedly connected with the rotary joints. The anti-blocking measure of traditional manual cleaning of the coal economizer is changed, a cleaning device and the coal economizer are combined together, and automatic cleaning work is achieved by operating the anti-blocking coal economizer structure, so the cleaning difficulty of the coal economizer is greatly reduced, the anti-blocking performance of the coal economizer is effectively improved, and the service life of the coal economizer is effectively prolonged.

Description

technical field [0001] The patent of the present invention relates to an anti-blocking economizer structure. Background technique [0002] The economizer is a device installed at the lower part of the boiler tail flue to recover the waste heat of the exhausted smoke. It heats the boiler feed water into a saturated water heating surface under the pressure of the steam drum. Because it absorbs the heat of the high-temperature flue gas, it reduces It improves the exhaust temperature of the flue gas, saves energy and improves efficiency, so it is called an economizer. [0003] During the long-term use of the economizer, due to the high temperature, it will cause problems such as pipe wall wear and inner wall corrosion. If it is not cleaned in time, the pipe will be blocked. The traditional cleaning method is often done manually, but due to the special structure of the pipe, it is very difficult to clean it. Difficult, time-consuming and labor-intensive, a new technology is need...

Problems solved by technology

[0003] During the long-term use of the economizer, due to the high temperature, it will cause problems such as pipe wall wear and inner wall corrosion. If it is not cleaned in time, the pipe will be blocked. The traditional cleaning method is often done manually, but due to the special structure of the pipe, it is very difficult to clean it. Difficult, time-consuming and labor-intensive, a new technology is needed to change the above problems
