Embodiment 1

[0023] Embodiment one, such as figure 1Shown, the titanium tetrachloride fluidized chlorination furnace gas-stop brick lining of the present invention is formed by laying bricks or stones by trapezoidal flat edge brick 1, and the two waist rectangular opposite faces in the six outer sides of long trapezoidal flat edge brick 1 and two Each group of opposite faces of the upper and lower trapezoidal opposite sides of the waist rectangle is made of a contact surface perpendicular to the long axis of the long trapezoidal flat side brick and corresponding to the convex edge of the groove, and the groove of the adjacent brick during masonry The contact surface and the rib contact surface are embedded with each other. The joints between adjacent bricks are bonded with a refractory adhesive. It has the advantages of preventing chlorine gas from penetrating through the brick lining brick layer from corroding the metal shell of the furnace body, and significantly prolonging the service ...

Embodiment 2

[0027] Embodiment two, such as figure 2 and 3 The whole side wall of the titanium tetrachloride fluidized chlorination furnace lining shown is circular, and the top surface and the bottom surface of the long trapezoidal flat edge brick 1 are the circle where the whole side wall of the titanium tetrachloride fluidized chlorination furnace lining is located. The center of the circle is the top convex arc surface and the bottom concave arc surface, and the middle horizontal groove 20 and the middle horizontal rib 21 are the middle horizontal straight groove and the middle horizontal straight rib (or the whole side wall of the titanium tetrachloride boiling chlorination furnace lining The center of the circle where it is located is the middle horizontal arc groove and the middle horizontal arc convex edge), and the middle vertical groove 30 and the middle vertical convex edge 31 are the middle vertical groove and the middle vertical convex edge.

Abstract

The invention relates to a gas stopping brick lining of a titanium tetrachloride boiling chlorination furnace and a furnace building method. The gas stopping brick lining is formed by building long trapezoid and flat-edge bricks, wherein in six outer edge surfaces of each long trapezoid and flat-edge brick, two waist rectangular opposite surfaces and each group of opposite surfaces in upper and lower trapezoid opposite surfaces parallel to the two waist rectangular opposite surfaces are provided with contact surfaces which are vertical to a long axis of each long trapezoid and flat-edge brickand correspond to grooves and convex edges respectively; in a building process, adjacent groove contact surfaces and convex edge contact surfaces of bricks are mutually embedded. The method comprisesthe following steps: building a lining brick layer in a metal shell of a furnace body through the long trapezoid and flat-edge bricks; in the six outer edge surfaces of each long trapezoid and flat-edge brick, forming the contact surfaces which are vertical to a long axis of each long trapezoid and flat-edge brick and correspond to grooves and convex edges on the two waist rectangular opposite surfaces and each group of the opposite surfaces in the upper and lower trapezoid opposite surfaces parallel to the two waist rectangular opposite surfaces respectively; in a building process, mutually embedding the adjacent groove contact surfaces and convex edge contact surfaces of the bricks. The gas stopping brick lining provided by the invention has the advantages of preventing chlorine gas frompenetrating through the lining brick layer from brick joints to corrode the metal shell of the furnace body, and remarkably prolonging the service life of the chlorination furnace.

Description

technical field [0001] The invention relates to a titanium tetrachloride ebullient chlorination furnace, in particular to an inner lining of a titanium tetrachloride ebullient chlorination furnace and a furnace building method. Background technique [0002] The brick type of the lining brick of the existing titanium tetrachloride chlorination furnace at home and abroad is a trapezoidal flat edge brick. During production, chlorine gas penetrates the lining brick layer from the brick seam to corrode the metal shell of the furnace body; the material of the brick is homogeneous inside and outside. The lining brick of the inner layer is damaged within 10-12 months by the erosion of boiling materials and the corrosion of concentrated chlorine gas, resulting in a short service life of the chlorination furnace and poor enterprise benefits. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, to provide...
