Self-washing end socket cover and heat exchange equipment

Abstract

The invention relates to the technical field of end socket covers, in particular to a self-washing end socket cover and heat exchange equipment. The self-washing end socket cover comprises an end socket shell (4) and a flow changing unit arranged in an end socket chamber defined by the end socket shell (4). The end socket shell (4) is provided with an inlet channel (5) and an outlet channel (6). The flow changing unit comprises a first flow changing structure. The first flow changing structure comprises a first tooth pipe (2). The first tooth pipe (2) is rotatably installed on the end socket shell (4). The outer surface of the first tooth pipe (2) is a tooth face. The first tooth pipe (2) extends into the end socket chamber from the inlet channel (5), so that flow entering from the inlet channel (5) flows through the outer surface of the first tooth pipe (2). The self-washing end socket cover can prevent pipe wall scaling and under-scaling corrosion.

Description

technical field [0001] The invention relates to the technical field of head covers, in particular to self-cleaning head covers and heat exchange equipment. Background technique [0002] According to statistics, the annual loss due to fouling and corrosion of heat exchange equipment such as head seals in my country is as high as more than 10 billion yuan. Since the flow velocity in some heat exchanger tubes is less than 0.9m / s, dirt can cause thermal resistance of heat exchange equipment. For every 1mm increase in fouling, the heat transfer coefficient will decrease by 9%-9.6%, and energy consumption and emissions will increase by more than 10%. Bring about the decline in production efficiency and increase in maintenance costs. Scaling and under-scaling corrosion on the surface of pipes such as heads and covers are likely to cause heat transfer problems, safety and environmental protection problems, and reduce efficiency. The above problems have been unsolved problems in coa...
