Description
Technical field
The invention belongs to coke oven for iron field, more particularly to a kind of high efficiency Riser waste heat recovery device for coke oven.
Background technology
Coke oven can do high-temperature retorting processing to coal, be efficiently converted to coke, coke-stove gas, coal tar, crude benzol
It is efficient energy conversion kiln Deng product.To hanker in coke oven expenditure, the heat of taking out of of 650 DEG C of -700 DEG C of raw coke oven gas accounts for 36%,
It is worth with high recycling.At present, generally use cools handling process to realize the commercial Application of raw coke oven gas, traditional work
Skill is：Spraying a large amount of 70 DEG C of -75 DEG C of cyclic ammonia waters to high temperature raw coke oven gas makes its cooling, waste heat recovery is realized, however, this can cause
High temperature raw coke oven gas is taken heat out of and wasted because of a large amount of evaporations of cyclic ammonia water.
In the 1980s, conduction oil was once used for tedge recovery raw coke oven gas by most of coke-oven plant of Japan takes heat out of：
Tedge is made jacket pipe by them, and conduction oil passes through jacket pipe and high temperature raw coke oven gas indirect heat exchange, heated high-temperature heat-conductive
Oil can be used for multiple use, such as ammonia still process, Doak Tar Oil, dry as-fired coal etc..Later, Ji steel in China's once rose in five holes
Pipe has carried out similar experiment；China's Wuhan Iron and Steel Plant, Ma Gang, Anshan iron and steel plant, ripples steel, Beijing coke-oven plant, the factory of Shenyang coal gas two, the iron of this steel one,
The many enterprises such as table mountain coke-oven plant once reclaimed this partial heat in tedge using water vapor cooling technology；In addition, also there is enterprise
Industry is used in method of the nitrogen as medium, with high temperature raw coke oven gas indirect heat exchange.
Existing coke oven coke oven uprising tube raw coke oven gas waste heat recovery takes the structure of thermal, in overall point, in, outer three layers of basic knot
Structure.Internal layer is high temperature resistant, the cylinder of corrosion resistant steel alloy material, and raw coke oven gas flows through from bottom to top in cylinder.Centre is core
Heart heat transfer layer, with high heat conduction ability, certain thickness high temperature resistant solid dielectric layer are closely attached to the outer wall of inner cylinder, heat transfer
Pipe is in close contact through solid dielectric layer, and with the solid dielectric layer, and what is flowed through in heat-transfer pipe is to take thermal medium, and it is being flowed over
The thermal discharge of raw coke oven gas in inner cylinder is absorbed in journey, temperature raises in flow process from bottom to top.On heat-transfer pipe or spiral
Rise and spiral in the solid dielectric, or be uprightly arranged in the solid dielectric layer from bottom to top, solid dielectric layer need to cover whole biography
The outer surface of heat pipe；Outer layer is heat insulation protecting layer, metal material cylinder, insulation material is posted on internal face, to inner cylinder and centre
Core heat transfer layer plays a part of being incubated and protected, and reduces heat loss, is not hit.
However, existing coke oven coke oven uprising tube raw coke oven gas waste heat recovery takes thermal problems with to be more or less present：Pass
The structure design of thermal process is unreasonable, circulation is not unobstructed enough, heat exchange efficiency is low, raw coke oven gas side wall tar bond cause to block it is waste
Gas passage, conduction oil coking and blocking conduction oil passage, easily corroded by medium etc. or can not effectively be solved driving and parking and ran
The problem of expanding with heat and contract with cold of journey, this causes above method to be either difficult to successful implementation or is difficult to gratifying effect.
The content of the invention
Technical problem：In order to solve the defects of prior art, the invention provides a kind of high efficiency coke oven coke oven uprising tube waste heat
Retracting device.
Technical scheme：A kind of high efficiency Riser waste heat recovery device for coke oven provided by the invention, including flue, set

There is one group of heat exchange disk, heat exchange disk is provided with one group of through hole, and coke removing appts are flexibly connected on the windward side of each disk that exchanges heat；It is described to change
Hot plate includes the medium inlet layer and media outlet layer of middle part connection, and the medium of the heat exchange disk of separable flue gas conduit entrance recently enters
Mouth layer is provided with the medium inlet of a pair of opposing, and the media outlet layer of the nearest heat exchange disk of separable flue gas pipe outlet is provided with a pair
The media outlet being oppositely arranged, one group of heat exchange disk are connected by medium pipeline；The coke removing appts include substrate and are fixed on base
High heat conduction silk screen on plate.
As an improvement, the heat exchange panel surface is provided with high heat conduction anti-coking composite coating, the high heat conduction anti-coking
