Background technology
China is power consumption big country, the industrial exhaust heat enormous amount, no matter be solid-state, gaseous state, that liquid state all has a large amount of industrial exhaust heats to have is to be recycled, thereby these waste heats in the enterprise production process recycled for energy efficiency very large society, economic benefit are arranged.Power consumption greatly in the process of coking, generally all be to adopt water cooling after red Jiao comes out of the stove in the past, it is the quenching of coke wet quenching method, this method does not reclaim the waste heat of high-temperature coke, and can consume a large amount of cooling waters, cause air and water pollution, big, the complex process of another kind of dry coke quenching method investment, adopt method and apparatus of the present invention have equipment simple, take up an area of advantages such as little, small investment, maintenance cost are low.
Summary of the invention
The present invention is to provide a kind of red burnt heat-recovering semiconductor thermal difference generation device, be intended to solve waste heat waste, the saving quenching cooling water problem of the high-temperature coke that produces in the process of coking.
Technical solution of the present invention: it is characterized in that comprising feeding gate, cylindrical shell, discharge door, and semi-conductor thermo-electric generation module and bosh, its middle cylinder body are cuboid, cylinder material is a metal high temperature resistant, good heat conductivity, is used for storing high-temperature coke; Feeding gate is located at an end of cylindrical shell, and discharge door is located at the other end of cylindrical shell, and feeding gate adopts the metal material identical with cylindrical shell with discharge door; Semi-conductor thermo-electric generation module is clipped in the middle of cylindrical shell and the bosh, and the hot junction face of semi-conductor thermo-electric generation module is pasting cylindrical shell, and the cold junction face of semi-conductor thermo-electric generation module is pasting bosh; In the middle of the bosh cooling duct is arranged, take away the heat that passes to semi-conductor thermo-electric generation module cold junction face by cooling-water flow; This device is arranged on the coal airing platform slope of carbonization chamber below, when red Jiao in the carbonization chamber is pushed out, the device feeding gate is opened, discharge door is closed, red Jiao to be cooled is pushed in the cylindrical shell, and feeding gate is closed, and red Jiao is closed in the device, by semiconductor temperature differential generating and cooling device red Jiao is cooled off, to reach the purpose of recovery waste heat generating; Red Jiao is closed in the device, avoids contacting with air and burning away, after the setting-up time that hot Jiao is closed, discharge door is opened automatically, red Jiao is by in the coke receiving car below the coal airing platform that come down in torrents, and sprinkler head sprays into cooling water immediately in coke receiving car, and thoroughly cooling is eclipsed to make red Jiao.
Advantage of the present invention: the waste heat of high-temperature coke can be directly changed into electric energy, need not earlier thermal power transfer to be become mechanical energy by traditional mode, again mechanical energy is converted to the complex process of electric energy, thereby improved the reliability and the useful life of conversion efficiency of thermoelectric and generator; Compare with other forms of waste-heat recovery device, the present invention is a kind of all solid state power conversion mode, has noiselessness, nothing wearing and tearing, no dielectric leakage, long service life in power generation process; Apparatus of the present invention are simple in structure, are convenient to processing, and utilize coke cogeneration, can reduce enterprise energy consumption, meet national industrial policies, are easy to apply.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Among the figure 1 is feeding gate, 2 cylindrical shells, the 3rd, bosh, the 4th, semi-conductor thermo-electric generation module, the 5th, discharge door, the 6th, sprinkler head.
Embodiment
Feeding gate and discharge door are dodge gates, carry out the automatic control of folding by controlling organization.
Described semi-conductor thermo-electric generation module is the core of semiconductor thermo-electric generation apparatus, its electricity generating principle is based on the Bezier effect, in P (N) N-type semiconductor N, the hole of temperature end (electronics) concentration ratio low-temperature end is big, under the driving of this concentration gradient, hole (electronics) can be spread to low-temperature end from temperature end, thereby form a kind of electrical potential difference owing to the thermal diffusion effect.The hot junction of P type and N type semiconductor is linked to each other, then can obtain a voltage at cold junction, such PN junction just can utilize the temperature difference between high temperature heat source and the low-temperature heat source directly to change heat energy into electric energy.
Temperature difference makes each to producing electrical potential difference in the PN junction, will be much to being together in series, just can obtain sufficiently high voltage, and become a thermal generator.
This device is installed on the slope of coal airing platform, and the feeding gate of device is opened during work, and discharge door is closed, high-temperature coke is released from carbonization chamber in the direct access to plant in back, then discharge door is closed, and coke is closed in the device, avoids contacting with air and burning away.The heat that red Jiao distributes in the cylindrical shell of sealing is delivered to the hot junction face of semi-conductor thermo-electric generation module by barrel, in bosh, feed simultaneously cooling water, take away the heat that is delivered to semi-conductor thermo-electric generation module cold junction face by flow of cooling water, make the cold junction face keep a lower temperature with respect to the hot junction face, both ends of the surface at semi-conductor thermo-electric generation module have just produced a temperature difference like this, according to the Bezier effect, in the semiconductor electricity generation module, produced electrical potential difference by this temperature difference, this electrical potential difference has been carried out rectification, promptly can be used as power supply after the AC-DC conversion uses.Through after the setting-up time, open automatically by the discharge door of device in cylindrical shell for red Jiao, and coke is poured on the coke receiving car of coal airing platform below, and sprinkler head sprays into cooling water in coke receiving car, coke is thoroughly cooled off, and finishes the quenching process.
Red Jiao: be meant the high-temperature coke that just has been pushed out from carbonization chamber, this moment, the high-temperature coke entire body took on a red color, and the flame of part of coke does not also extinguish fully.
