Washing descaling ball with mesh surface

A washing descaling ball with a mesh surface belongs to the fields of in-tube washing descaling and heat transfer enhancement. The washing descaling ball is composed of an inner ball and the mesh surface, and an outer surface of the ball is a compact surface. An outer surface of the inner ball and an inner surface of the mesh surface, a plurality of intensive mesh net-shaped meshes are arranged on the mesh surface, and annular or football-shaped frames or circular mesh separation sheets which are mutually crossed are arranged between the meshes. A mesh surface structure with a plurality of holes has good elasticity and dense scratching edges so that the washing descaling ball has excellent washing descaling effects and is not prone to block a tube to be washed. A compact ball outer surface does not absorb water and swell in a using process so that density and size stability of the washing descaling ball can be kept in a long-time using process, a problem that the existing sponge gelatin ball has big changes in the using process to have influences on washing effects is solved, and normal operation in a cold season can be guaranteed. An inner solid structure is not prone to squeeze out from a mesh of a ball screen or block in the mesh of the ball screen, and ball collection rate and operation circulation rate are high.
