Novel heat transfer temperature field and solid-state furnace slag propelling system

Abstract

The invention discloses a novel heat transfer temperature field and solid-state furnace slag propelling system. The system is characterized by comprising a base 1 and bosses 2; one surface of each boss 2 is a curved surface 3, and the other surface of each boss is a plane 4; each curved surface 3 is downwards; a warm heat output joint 5 is formed in the convex surface of each boss 2, is of a funnel-shaped mirror surface structure, and is connected with a heat conducting fiber 6; a computer finite element three-dimensional analysis method is adopted to fully heat water and slag; compared with the prior art, the novel heat transfer temperature field and solid-state furnace slag propelling system adopts a special boiler fitting material for corrosion resistance, deviation is low, the falling problem of blades in heat exchange tubes is solved, and further the heat exchange area is effectively increased; meanwhile, because of rolling friction between the slag and metal pipe walls, the friction coefficient is reduced, the service life of a cold slag machine is prolonged, and the reliability is improved; the equipment and the technological method are simple in structure, low in resistance, low in product operation cost, few in wearable parts, low in equipment maintenance cost, small in equipment size, low in steel consumption and low in cost, the material utilization rate is effectively improved, the product structures are optimized, the costs are reduced, and the product strength is guaranteed.

Description

technical field [0001] The invention relates to the technical field of equipment design for a boiler slag cooling machine node eh dog optimization system, in particular to a novel heat transfer temperature field and a solid slag propulsion system. Background technique [0002] Boiler equipment is widely used in thermal power, heating, chemical industry, papermaking industry, etc., but most boilers are chain-type layer-fired boilers. These traditional combustion boilers generally have low combustion efficiency and poor adaptability to coal types. However, the circulating fluidized bed boiler equipped with cooling slag equipment in the existing boiler equipment has poor cooling effect, high operation failure rate, and heavy maintenance workload. Stable, long, full and optimal operation brings great hidden dangers, so many users urgently need to replace outdated cooling slag equipment with new-type cooling slag equipment. [0003] In order to well solve the above problems, the...

Problems solved by technology

[0004] The purpose of this invention is to provide a new type of heat transfer temperature field and solid slag propulsion system, using special anti-corrosion boiler accessories materials, the deviation is less than 1.88MM, disperse and cool the slag through multiple cooling slag tubes, and solve the problem of blade falling off in the heat exchange tube problem, the heat exchange area is further effectively increased, and at the same time, due to the rolling friction between the slag and the metal pipe wall, the friction coefficient is reduced, which improves the service life and reliability of the cold slag holiday. The equipment and process method are simple in structure and small in resistance. The product has low operating costs, fewer wearing parts, low equipment maintenance costs, the same heat transfer area and cold slag volume, small equipment volume, less steel consumption and low cost, effectively improving material utilization, optimizing product structure and reducing costs , to ensure the strength of the product
