Abstract
The utility model relates to a ceramic-lined composite nozzle for a high-temperature furnace. A nozzle body comprises a front-end ceramic piece and a rear-end stainless steel member, wherein the ceramic piece and the stainless steel member are combined by adopting interference fit; a nozzle joint of the stainless steel member adopts threaded connection; and an inner cavity of the composite nozzle is round-platform-shaped. The ceramic-lined composite nozzle adopts high-strength ceramic materials, has the characteristics of high hardness, wear resistance, high temperature resistance and corrosion resistance and the like, and has good hardness and cracking performance under high temperature; the metal material adopts 316 stainless steel without rusting and pollution; the metal materials and the ceramic piece adopt interference fit, and the combination is firm; and the joint part adopts threaded connection, so that the installation and the disassembly are convenient. The product can be normally used under high temperature, high pressure and corrosion environment, the average life of the product is longer than that of the common metal nozzle, and the popularization and application values are better.
Description
Technical field
The utility model relates to a kind of high temperature furnace used nozzle, particularly relates to a kind of high temperature furnace used ceramic-lined combining nozzle.
Background technology
The nozzle of high temperature furnace used various bores adopts the heat-resisting steels manufacturing at present, this steel nozzle easy abrasion, and service life is shorter; Main cause is that the steel nozzle on the distributor pipe is difficult to bear long thermal-flame calcination under the high temperature; Be prone to cause loss, and nozzle is welded on directly on the matrix of reactor, maintain and replace is extremely inconvenient; Thereby influence productivity effect, increase the enterprise production cost.
The utility model content
The technical problem that the utility model will solve:, a kind of high temperature furnace used ceramic-lined combining nozzle of easy to use, high temperature resistant, corrosion-resistant, long service life is provided to the deficiency that prior art exists.
The technical scheme of the utility model:
A kind of ceramic-lined combining nozzle comprises nozzle body, and said nozzle body comprises the ceramic member of front end and the stainless steel component of rear end, adopts interference to be fitted to each other between ceramic member and the stainless steel component, and the nozzle interface place of stainless steel component adopts and is threaded; The inner chamber of combining nozzle is round table-like.
The end face of said stainless steel component is a bolt shape, also is provided with boss on the stainless steel component.
Said ceramic member is processed by high-intensity aluminium oxide ceramics; The rear end of nozzle body is 316 stainless steel components.
The positive beneficial effect of the utility model:
(1) the ceramic-lined combining nozzle of the utility model; The nozzle body front end adopts ceramic-lined; Stainless steel component is adopted in the nozzle body rear end, compares with common steel nozzle, because nozzle adopts high strength ceramic material; Have hardness height, characteristics such as wear-resisting, high temperature resistant and corrosion-resistant, nozzle at high temperature has good hardness and cracking resistance.
(2) metal material of the utility model nozzle adopts 316 stainless steel materials, and non-corrosive does not pollute, and firm with the ceramic member assembling, nozzle interface partly adopts and is threaded, and makes things convenient for installing/dismounting, and is safe and reliable.
(3) jet expansion of the utility model partly is full ceramic structure, under HTHP and corrosive environment, can normally use, and the product average life span than the long 5-10 of metallic nozzle doubly has using value preferably.
(4) the utility model can be applicable to the nozzle of various high temperature furnaces, and like incinerator nozzles, heat-engine plant desulfurized nozzle, rotary kiln coal burner nozzles etc., purposes is wider.
