Abstract
The utility model relates to an enamel steel pipe type air heat exchanger which is composed of a pipe sheet, a heat exchanging pipe, sealing materials and a casing, wherein, the heat exchanging pipe is sealed and connected with the pipe sheet by the sealing materials composed of an asbestos rope and water glass; the heat exchanging pipe is composed of three layers of materials, the inner layer is a steel pipe, and the outer surface of the steel pipe which is positioned at the inner layer is covered with a sealing layer; the outside of the sealing layer is covered with an enamel layer; the heat exchanging pipe and the pipe sheet are coated by the casing. The utility model has the advantages of tight combination, difficult damage, smooth surface, the good sealing effect, no ash blockage, corrosion resistance and long service life.
Description
The utility model belongs to a kind of glassed steel tubular type air heat exchanger, is particularly suitable on the boiler device of exchange heat between air and this two media of flue gas.
Existing enamel steel pipe type air heat exchanger, its heat exchanger tube is made up of two-layer, adheres to glass-lined coating on the steel pipe layer, and its hermetically-sealed construction is an asbestos packing, poor sealing performance.Though this heat exchanger has solved cold end corrosion of former steel pipe type air heat exchanger and quick abrasion problem, its outer surface enameling glass layer fragility is big, cracky, and sealing is poor between two media, and it is serious to leak out.
The purpose of this utility model provides the glassed steel tubular type air heat exchanger of a kind of not cracky, good seal performance, long service life.
The utility model is made up of tube sheet, heat exchanger tube, encapsulant and housing.It is characterized in that heat exchanger tube is installed on the tube sheet by the encapsulant sealing, the sealing material is made of asbestos cord and waterglass, after it solidifies, heat exchanger tube and tube sheet can be closely linked.Heat exchanger tube is formed by three layers, and internal layer is a steel pipe, is attached with close binder on the outer surface of steel tube of internal layer, is attached with enamel layer on close binder, and housing is coated on heat exchanger tube and tube sheet therebetween.
The utility model close binder is that frit, borax, ripe quartz, soda ash, five kinds of materials of clay are processed according to a certain percentage and mixed the back high temperature sintering and form.
Because the utility model is provided with close binder between steel pipe layer and enamel layer, thereby can make enamel attached to more firm on the steel pipe, cracky does not increase the service life.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a main pseudosection of the present utility model;
Fig. 2 is a side cutaway view of the present utility model;
Fig. 3 is a heat exchanger tube profile of the present utility model.
The utility model is horizontal layout, is made up of tube sheet 7, heat exchanger tube 5, encapsulant 4 and shell 6, it is characterized in that: heat exchanger tube 5 sealing is installed on the tube sheet 7, and heat exchanger tube 5 is made up of trilaminate material, and internal layer is a steel pipe 2, and thickness is 1.5mm; Outer surface at inner layer steel pipe 2 is attached with close binder 1, close binder 1 at high temperature forms through sufficient physics and chemical reaction sintering after processing mixing according to a certain percentage by frit, borax, ripe quartz, soda ash, five kinds of materials of clay, and thickness is about 0.1mm; Be attached with enamel layer 3 on close binder 1, thickness is 0.2-0.25mm.Housing 6 is coated on heat exchanger tube 5 and tube sheet 7 therebetween.
Claims (2)
1 one kinds of glassed steel tubular type air heat exchangers, form by tube sheet (7), heat exchanger tube (5), encapsulant (4) and shell (6), it is characterized in that: heat exchanger tube (5) sealing is installed on the tube sheet (7), heat exchanger tube (5) is made up of trilaminate material, internal layer is a steel pipe, outer surface at inner layer steel pipe (2) is attached with close binder (1), is attached with enamel layer (3) on close binder (1), and housing (6) is coated on heat exchanger tube (5) and tube sheet (7) therebetween.
2 glassed steel tubular type air heat exchangers according to claim 1 is characterized in that close binder (1) is made of by a certain percentage frit, borax, ripe quartz, soda ash, five kinds of materials of clay.
