An anti-blocking economizer structure

Abstract

The invention discloses a novel anti-blocking economizer structure, comprising a shell, a flue gas delivery pipe, a distribution pipe, a water inlet main pipe, a water outlet main pipe, a flue gas outlet pipe, a heat exchange pipe, and a connecting pipe. The pipe is connected to the distribution pipe through an elbow, and the flue gas delivery pipe is connected to the boiler tail flue. The lower part of the elbow at the end of the flue gas delivery pipe is welded with a quick dredging pipe. The distribution pipe extends into the shell, and the top of the distribution pipe is Blocking design, the distribution pipe is welded with multiple connecting pipes, the connecting pipes are distributed equidistantly along the vertical direction of the distribution pipe, the end of the connecting pipe is connected with the flue gas outlet pipe, and the flue gas outlet pipe is located in the shell, and the flue gas outlet One end of the pipe is designed to be blocked, and the other end is connected to the chimney through which the flue gas is discharged. One side of the exterior of the casing is provided with a water inlet pipe, and the other side of the exterior of the casing is provided with a water outlet pipe. The design of the invention is reasonable; the design of a plurality of connecting pipes can be used according to the required quantity so as to perform different heat exchanges.

Description

technical field [0001] The invention relates to a novel anti-blocking economizer structure. Background technique [0002] Coal is the conventional energy with the most reserves and the widest distribution in the world, and it is also the cheapest energy. The storage of coal in northern my country is relatively large, so coal plays an important role in northern my country. In order to convert the energy of coal into the energy that people need , People often use boilers to burn coal to generate steam, and use steam to perform various operations. Coal combustion will produce a large amount of flue gas, and the temperature of the flue gas is also high. The concept of discharge, using the economizer to absorb the heat of the high-temperature flue gas from the boiler, so as to save energy and improve efficiency. The existing economizer will be blocked during use. It is not easy to handle and thus affect production. Contents of the invention [0003] The object of the present inv...
