Technical Field
The invention relates to the technical field of coke ovens, in particular to a coke oven regenerator adopting a filler mode for heat exchange.
Background
The coke oven consists of five parts, namely a regenerator, a chute, a carbonization chamber, a combustion chamber and a furnace top; the regenerator is arranged at the lower part of the furnace body, the carbonization chambers and the combustion chambers are alternately arranged, the carbonization chambers and the combustion chambers are separated by refractory brick walls, each combustion chamber is provided with 28-36 vertical flame paths, and the inclined paths are furnace tops of the furnace body above the combustion chambers and connected with the channel carbonization chambers between the vertical flame paths of the combustion chambers and the regenerator. The gas and air for heating are preheated by high-temperature waste gas in the heat storage chamber, the preheated gas (the high-heat value gas is not preheated) and the air meet and burn at the bottom of the vertical fire channel, heat is provided for the carbonization chamber from the side face, and the coal in the carbonization chamber is heated to be changed into coke under the condition of air isolation.
When the regenerator descends high-temperature waste gas, most heat is absorbed and accumulated, so that the temperature of the waste gas is lowered from about 1200 ℃ to below 400 ℃; when the lean gas or air rises, the stored heat is transferred out, so that the lean gas or air is preheated to more than 1000 ℃. Half of the regenerators of each coke oven are always in descending air flow, and half of the regenerators are in ascending air flow, and reversing is carried out once every 20-30 minutes. At present, the conventional heat storage chambers are internally provided with checker bricks as heat storages, the dry-discharge masonry process is time-consuming and labor-consuming, the holes of the checker bricks are easy to block, the heat exchange effect is affected, and high-temperature waste gas cannot be discharged when serious, so that high-temperature accidents can be caused.
Disclosure of Invention
The invention provides a coke oven regenerator adopting a filler mode for heat exchange, which adopts random heat storage filler as a regenerator, has simple structure and convenient construction, can quickly and efficiently absorb the heat of descending waste gas, and has higher efficiency of heating ascending lean gas or air.
In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
A coke oven regenerator adopting a filler mode for heat exchange comprises random heat accumulation filler and an air flow distributor; and a layer of multi-layer airflow distributor is arranged in the coke oven heat storage chamber along the high direction, and random heat storage filler is filled in the upper space of the airflow distributor or in the interlayer space between the airflow distributors.
The coke oven regenerator is of a grid structure, and is divided into a plurality of regenerator grids from the machine side to the coke side, and each regenerator grid corresponds to one vertical flame path respectively; and a plurality of layers of air flow distributors are arranged in the inner side of each regenerator cell along the height direction, and random heat accumulation filler is filled in the upper space of each air flow distributor or in the interlayer space between each layer of air flow distributor.
The random heat storage filler is one or a mixture of a plurality of honeycomb, annular or wing random heat storage fillers.
The random heat storage filler is made of ceramic or metal.
Compared with the prior art, the invention has the beneficial effects that:
1) The random heat storage filler has good heat exchange effect, firm structure, wear resistance, easy mass production and repeated recycling;
2) The construction is convenient, compared with the existing checker brick heat accumulator, the dry-row masonry is not needed, and the time and the labor are saved;
3) One or more layers of air flow distributors are arranged, so that the air flow is more uniform, and the heat exchange effect is improved;
4) The regenerator with the cellular structure not only has better heat exchange effect, but also is beneficial to thermal regulation.
