Description
Technical field:
The utility model belongs to the gangue brick residual heat of tunnel kiln and utilizes technical field.
Background technology:
The colliery has produced a large amount of gangues in coal mining and washing process, both taken a large amount of soils, again environment has been caused serious pollution, is one of important channel of gangue comprehensive utilization with making coal gangue brick.Making coal gangue brick is gangue to be pulverized back adding batching make the gangue adobe, by autoignition sintered form of gangue adobe in tunnel cave, tunnel cave is divided into preheating section, sintering stage, cooling section, in the sintering process of gangue brick, the a large amount of heat energy that produces, produce the brickmaking tunnel cave of 5,000 ten thousand lump coal spoil brick scales per year, the heat that produces in the gangue brick sintering process in a year is about 65,000,000,000 kilocalories.At present, these heat major parts are wasted, and a kind of simple UTILIZATION OF VESIDUAL HEAT IN mode is that the molten iron case is directly placed tunnel kiln sintering section top, with the water heating, with the form supply publilc baths water or the heating of hot water.The main deficiency that this technology exists has: 1, the hot gangue brick of distance from bottom is far away because water tank absorbs heat, and causes heat conduction efficiency lower.2, since with water as heat catalysis, directly use the heating of former water, the water tank scale velocity is very fast, form thermal insulation layer after the fouling, not only reduced heat utilization efficiency, and since the water tank low layer by dry combustion method, often burnt and leaked, the maintenance that need stop production, influence is produced, waste material.3, adopt hot water heating, because the pipeline heat loss is big, the heat energy utilization rate is low.4, with respect to steam boiler, because influences such as the hot water temperature that the water tank heating produces, pressure, the afterheat utilization scope is subjected to bigger restriction, can not be as power and other production field.
The utility model content:
In order to overcome the service life of equipment weak point, the high material consumption that exist in the existing gangue brick residual heat of tunnel kiln utilization, to influence gangue brick ordinary production, the narrow deficiency of waste heat purposes, concrete characteristics in conjunction with the gangue brick tunnel cave, the utility model provides a kind of gangue brick residual heat of tunnel kiln use device, with the surplus vapours that is converted to of gangue brick tunnel cave.
The utility model comprises: drum, adopt heat pipe, left side upper collecting chamber, lower-left collection case, the kiln body, bottom right collection case, right upper collecting chamber, down-comer, wireway, water inlet pipe, escape pipe, water inlet pipe and escape pipe are arranged on drum top, drum vertically is arranged in kiln body top along tunnel cave, left side upper collecting chamber, lower-left collection case, bottom right collection case, right upper collecting chamber is fixedly installed on the body of wall inside of kiln body both sides, adopt the even lateral arrangement at interval of heat pipe in kiln body inner and upper, lower-left collection case and bottom right collection case are connected to the drum bottom by down-comer respectively and are interconnected, left side upper collecting chamber is communicated with drum by wireway respectively with right upper collecting chamber, left side upper collecting chamber is communicated with by adopting heat pipe with bottom right collection case, and lower-left collection case is communicated with by adopting heat pipe with right upper collecting chamber.
Like this, after the bastard coal adobe enters the tunnel cave body, rely on the spontaneous combustion of gangue to carry out sintering, behind sintering, enter cooling section at sintering stage.Hot bastard coal waste heat discharges at cooling section, this device forms boiler combustion system with the cooling section of tunnel cave, drum, adopt heat pipe, left upper collecting chamber, lower-left collection case, bottom right collection case, right upper collecting chamber, down-comer, wireway and form the carbonated drink closed circuit, neither influence cash brick sintering quality, guarantee the ordinary production operation of tunnel cave, can effectively residual heat of tunnel kiln be converted into heat steam again, as uses such as heating, heating, power, improve UTILIZATION OF VESIDUAL HEAT IN efficient, enlarged the heat energy utilization scope.Because use of the present utility model has replaced coal-burning boiler, the needed fuel of coal-burning boiler, electric power of equipment and labour cost have not only been saved, and reduced the air pollution that causes because of coal-fired, and played effects of energy saving and emission reduction, can be enterprise and bring remarkable economic efficiency every year.
