Description
Technical field
The utility model is related to coke oven coke oven uprising tube raw coke oven gas heat recovery technology field, more than specifically a kind of coal oven dithio-gas
Recuperation of heat heat exchange tedge.
Background technology
Coke oven coke oven uprising tube raw coke oven gas is taken heat out of and accounts for the 35% or so of coke oven quantity of heat given up, with a relatively high recycling
It is worth, Ge great Coke-oven Design institute and Ge great coke-oven plant have all successively put into huge manpower and materials, also successively have developed multiple
The tedge heat exchanger pattern of type and technology, National Development and Reform Committee have also put into huge fund for developing technique, main
The technology such as conduction oil jacket pipe, heat pipe, boiler and semiconductor temperature differential generating are concentrated on, is reclaimed raw coke oven gas and takes heat out of, but
Up to the present, tar condensing coking in problems, particularly raw coke oven gas, graphite mounting, floccule blocking, heat exchange are still suffered from
Face because corrode leak, heat exchanger high-temperature expansion uneven the problems such as, seriously hinder being smoothed out for waste heat recovery, such case it
Under want to solve problem above well, its core is intended to select stable, reliability, high-efficiency heat conduction material, raw coke oven gas and heat exchange to be situated between
Matter can will reclaim quickly through heat exchanger and to greatest extent raw coke oven gas waste heat.
Content of the invention
The utility model aim to provide one kind can make that heat-transfer surface is corrosion-resistant, non-caked tar or floccule blocking, and
Have the advantages that corrosion-resistant, high temperature resistant, resistance to dry combustion method, it is capable of the coke oven coke oven uprising tube raw coke oven gas waste heat recovery of trouble free service steadily in the long term
Heat-exchanger rig.
For achieving the above object, the technical solution adopted in the utility model is as follows：A kind of waste heat of coke oven crude gas is reclaimed and is changed
Hot tedge, including：Water leg, metal heat conducting-body, alloy inner core, described alloy inner core one end are connected with coal oven dithio-gas outlet
Connect, the alloy inner core other end is connected with drum, it is characterised in that：The heat-exchanger rig is followed successively by alloy inner core, gold from the inside to the outside
Category heat carrier, water leg；With Ceramic glaze coating on the inside of described alloy inner core；The thermal coefficient of expansion of the metal heat conducting-body
Consistent with water leg and alloy inner core.
Further, the outer surface of the Ceramic glaze coating is that one layer of smooth and hard heat conducting energy-saving anti-corrosion of black is applied
Layer.
Further, the water leg outer wrapping adiabator layer.
Further, install outside the water leg for prevent the long-time dry combustion method of this heat-exchanger rig infrared thermometer or
Band teletransmission temperature thermocouple.
The beneficial effects of the utility model are：This device adaptability for working condition is strong, durable for a long time recovery raw coke oven gas to greatest extent
The features such as sensible heat, the device is arranged on original tedge and is connected with bridge tube discharge, effectively can reclaim more than raw coke oven gas
Heat, and reduce next link ammoniacal liquor consumption, save power usage, reduce treatment cost, reduce environmental pollution.
Description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
In figure：1st, water leg；2nd, metal heat conducting-body；3rd, alloy inner core；4th, bristol glaze finishing coat.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is further described, only of the present utility model is below embodied as
Example, is not limited to the utility model.
As shown in drawings, a kind of waste heat of coke oven crude gas reclaims heat exchange tedge, including：Water leg 1, metal heat conducting-body 2,
Alloy inner core 3, described 3 one end of alloy inner core are connected with coal oven dithio-gas outlet, and the alloy inner core other end is connected with drum, its
It is characterised by：The heat-exchanger rig is followed successively by alloy inner core 3, metal heat conducting-body 2, water leg 1 from the inside to the outside；In described alloy
3 inner side of cylinder has Ceramic glaze coating 4；The thermal coefficient of expansion of the metal heat conducting-body 2 and water leg 1 and the one of alloy inner core 3
Cause.
The outer surface of the Ceramic glaze coating 4 is the smooth and hard heat conducting energy-saving corrosion-inhibiting coating of one layer of black.
1 outer wrapping adiabator layer of the water leg.
Install outside the water leg 1 for preventing the infrared thermometer of this heat-exchanger rig long-time dry combustion method or band teletransmission from surveying
Warm galvanic couple.
Principle of the present utility model is：Raw coke oven gas heat after 3 inwall of alloy inner core exports to outer wall, metal heat conducting-body
Heat on outer wall is quickly derived by 2；After metal heat conducting-body 2 quickly absorbs raw coke oven gas heat, transmission feedwater is vaporized heat absorption,
Due to heat-exchanger rig and iron and steel material quality, its thermal conductivity factor increases its heat exchange area as inner core, and heat exchange area is more than inner core
Outer wall heat-conducting area, heat fast and effeciently conduct；Fully ensured that by forced circulation pump and the configuration of rational step caliber every
The water inlet of the special heat-exchanger rig of individual tedge is relatively uniform, can reclaim raw coke oven gas waste heat to greatest extent, and inwall has not
Easy-adhesion, easy self falling, with certain self-cleaning ability.
