A net includes a bag body, an endless suspension rope, and a top closing rope. The bag body prevents scour of an underwater structure, and is formed into a mesh by a knitted fabric. The endless suspension rope is inserted through the mesh adjacent to an opening portion of the bag body. The top closing rope closes the opening of the bag body, and is inserted through a mesh adjacent to the mesh through which the suspension rope is inserted.

Material and construction method of prevention of scour for the underwater structure

An apparatus for removing acid constituents such as HCl and/or SO.sub.x from the waste-gas generated by furnaces,incinerators and the like wherein the calcium-containing powder material is blown into a waste-gas duct to form a lean fluidized flow until it reaches a vertical moving bed filter having two louvered walls between which granular packings are filled. The process for removing the acid constituents is accomplished by chemisorption which occurs first in the duct and then in the filter bed. A recycled use of the powder is preferred. The filtered waste-gas is further purified by an electrostatic precipitator. The use of a moving bed filter permits the use of a greater amount of calciumaceous powder relative to the acid gases without increasing the electrical load on the electrostatic precipitator.
