Pure-titanium plate anti-corrosion device of brick inner tube chimney

The invention provides a pure-titanium plate anti-corrosion device of a brick inner tube chimney. The pure-titanium plate anti-corrosion device comprises keels fixed on the inner wall of the chimney, wherein the keels comprise tube wall keels and vertical keels; the tube wall keels are in an annular shape coaxial with the chimney; the plurality of tube wall keels are sequentially arranged in the axial direction of the chimney; the plurality of vertical keels are spliced between the two adjacent circles of tube wall keels; a position between the adjacent keels is filled with a cement mortar layer; and a tubular titanium plate is fixed at the inner sides of the keels. The pure-titanium plate anti-corrosion device has the advantages that the structure is simple; the construction is convenient; the service life is long; and the anti-corrosion effect is excellent. 本发明提出种砖内筒烟囱纯钛板防腐装置，包括固定在烟囱内壁上的龙骨，所述龙骨包括筒壁龙骨和竖向龙骨；所述筒壁龙骨为与烟囱同轴的圆环状，若干所述筒壁龙骨沿烟囱的轴向依次设置；相邻两圈筒壁龙骨之间拼接有若干所述竖向龙骨；在相邻龙骨之间填充有水泥砂浆层；所述龙骨内侧固定有筒状钛板。本发明结构简单，施工方便，寿命
