Abstract
The utility model provides a novel high-temperature air preheater. The shell of the novel high-temperature air preheater has a jacket structure; the inner layer is made of 2mm 310S stainless steel; the outer layer is made of 16mm Q245R carbon steel; and the liner of the shell of the novel high-temperature air preheater is made of a 150mm light refractory material. By the novel high-temperature air preheater, manufacturing cost is largely reduced, shell intensity is increased, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, especially a kind of shell mechanism of heat-exchanger rig.
Background technology
At present, furnace black production is with the domestic tubular heat exchanger that all adopts of air preheater, and flue gas is walked tube side, and air is walked shell side.The general senior heat-resisting steel materials such as 309S, 310S that adopt high thickness of housing.Because the furnace black production technology improves and the production capacity enhancing now, and is also more and more higher to the requirement of technique air quantity and temperature in order to reach manufacturing technique requirent, causes immediately the increase of air preheater heat exchange area.Because the high temperature of plant air and carbon black smoke easily causes housing distortion, most domestic device fabrication producer adopts the thickness that increases steel to gain in strength.Come immediately will inevitably the increase of generating material cost, the problems such as selection waste.And simple increase can not effectively improve the short problem of service life of equipment with the thickness of steel product that high-temperature medium directly contacts.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art and a kind of high-temperature air preheater is provided, and service life of equipment can be prolonged more than 2 times.
The utility model is by the following technical solutions: a kind of high-temperature air preheater, comprise plant bottom case, heat-exchanging tube bundle, apparatus casing, FlexbleJoint, it is characterized in that apparatus casing is jacket structured, internal layer is the 310S stainless steel of 2mm, skin is the Q245R carbon steel of 16mm, and being lined with thickness in the apparatus casing is the 150mm lightweight refracrory.
Compared with prior art, the utility model has the advantages that: decrease the device fabrication cost; Increased apparatus casing intensity; Increase the service life.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is housing cross section structure schematic diagram of the present utility model.
Among the figure: 1 is that base, 2 is that heat-exchanging tube bundle, 3 is that housing, 4 is FlexbleJoint, and 5 is lightweight refracrory, and 6 is outer, and 7 is internal layer.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, a kind of high-temperature air preheater, comprise plant bottom case 1, heat-exchanging tube bundle 2, apparatus casing 3, FlexbleJoint 4, it is characterized in that apparatus casing 3 is for jacket structured, internal layer 7 is the 310S stainless steel of 2mm, outer 6 is the Q245R carbon steel of 16mm, and being lined with thickness in the apparatus casing 3 is 150mm lightweight refracrory 5.
