Description
Technical field
The utility model relates to a kind of kiln cooling chamber, and this kiln cooling chamber structure directly can carry out water cooling, and save the energy, cooling effectiveness is high, and cost is low.
Background technology
Kiln is the necessary equipment of fragment of brick or ceramic firing, and the development of kiln runs through the history of the whole mankind, and faced by present stage, traditional energy reserves reduce day by day, and energy prices rise violently, and environmental pollution is day by day serious, and energy-saving and emission-reduction have just become the important indicator considering furnace performance.
Existing kiln is when cooling, particularly process in blue bricks cooling procedure need to be full of in kiln water vapour stop air too much to enter time, generally adopt and come in two ways to carry out cooling down to the burned product in kiln body and kiln, one is adopt pump to be pumped into by water in kiln body, two is adopt drink firer sequence, the extensive mode of flood irrigation of namely watering to kiln body.Because kiln temperature is higher, usually all remain on 800 ~ 900 DEG C, as adopted the mode pumped into, cooling water is when through kiln body, meeting instant vaporization, cause pressure to rise sharply, cooling water can flow backwards, and so just needing more powerful pump that intake pressure is increased could pump in kiln body by cooling water, virtually add huge production cost, and the cooling water pumped into is easy to produce bubble, and then brings more air into, is unfavorable for brick firing.Namely to water directly to kiln body the mode of flood irrigation as adopted drink firer sequence, because the most of cooling water watered on kiln body is all evaporated, can only can soak infiltration kiln body wall and enter in kiln body by little a part of cooling water, innermost layer wall and burned product only can be relied on to carry out heat exchange, energy waste is very serious, and this type of cooling, at least need the time of more than 5 days, when adding that cooling water soaks the nexine wall penetrating into kiln body, temperature has increased many, therefore quite low with the heat exchange efficiency of burned product, the utilization rate of cooling water is in urgent need to be improved.
Certainly, also someone attempts adopting other modes to carry out air-isolation cooling, in kiln, pass into the mode such as inert gas, nitrogen as taked and discharge air body, but because the gas price such as inert gas, nitrogen is expensive, production cost is high, and tool easily impacts environment, well production cost can not be reduced.
Utility model content

Cooling tube and cooling tank or extraneous cooling system mode of communicating various, comprise cooling tube and be directly communicated with cooling tank, now the apopore of cooling tank still can pass into cooling water; Cooling tube also directly can be communicated with cooling tank apopore, is beneficial to controlled cooling model water and all enters from cooling tube; When running through connection, comprise cooling tube to be communicated with extraneous cooling system after the apopore of cooling tank runs through cooling tank, also comprise and get around apopore and directly run through cooling tank and be communicated with extraneous cooling system, also comprise before cooling tube enters cooling tank and carry out branch design, namely multiple path is divided into, wherein a forehearth limb is communicated with the apopore of cooling tank, one or more path runs through cooling tank and is communicated with extraneous cooling system in addition, or adopt other to run through mode, thus in kiln intracoelomic cavity, cooling water can be introduced more easily, accelerate cooling velocity, promote cooling effect.
Further, described cooling tube is offered at least one steam pressure release aperture, to carry out quick pressure releasing to the steam in cooling tube, prevent cooling water from flowing backwards.
Be further, when the joint face arranging one or more steam pressure release aperture and be positioned at steam pressure release aperture foremost and cooling tank is circumscribed structure, to carry out moment pressure release to the steam just entered in kiln intracoelomic cavity cooling tube, prevent water vapour from flowing backwards further, to introduce cooling water better in kiln intracoelomic cavity, other steam pressure release aperture can carry out pressure release to cooling tube further, make water vapour enter kiln intracoelomic cavity smoothly.
Further, described steam pressure release aperture is distributed on cooling tube, makes heat exchange between the burned product in kiln intracoelomic cavity and cooling water (water vapour) more even, improves quality of finished.
Further, when cooling tank and cooling tube run through be connected time, described cooling tube arranges a Water flow control valve at the leading portion stretching out cooling tank, is convenient to the flow from external control cooling water.
Further, when cooling tank and cooling tube are connected, described cooling tube arranges a Water flow control valve at the leading portion be connected with cooling tank, is convenient to the flow of controlled cooling model water.
Be further, described cooling tube comprises VERTICAL TUBE and horizontal tube, wherein, the upper end of VERTICAL TUBE is communicated with cold water bucket or runs through connection, lower end is communicated with horizontal tube, horizontal tube extends layout along the inwall of kiln body, when cold water enters into kiln intracoelomic cavity, be subject to the high temperature of degree more than 800, can by instant vaporization, the extension of VERTICAL TUBE and horizontal tube is arranged, these steam can be incorporated into each position in kiln inner chamber, make chilling temperature in kiln intracoelomic cavity and cooling velocity more evenly and balance, improve product qualified rate and quality further.
Further, described cooling tube is arranged in the inner chamber of kiln body, to promote cooldown rate in many rows or multiple row.
Owing to have employed said structure, cooling water directly can be introduced in kiln body without the need to high powered water pump and form water vapour by the kiln cooling chamber that the utility model provides, heat exchange is carried out with burned product, its heat exchange efficiency is high, the utilization rate of cooling water is high, cooling cost reduces, cool time is shorter, general a few hours can complete cooling procedure, the output of burning till product improves greatly, cooling water is directly introduced into formation water vapour, discharge air in kiln body under the effect of the pressure, burned product can be made to cool fast under anaerobic or micro-oxygen environment, prevent a large amount of generations of di-iron trioxide, be particularly suitable for brick firing, even if cooling water can be vaporized on a small quantity when entering kiln body, also moment pressure release can be carried out by the steam pressure release aperture on cooling tube, prevent cooling water from flowing backwards, make it naturally flow in kiln body and carry out heat exchange, in cooling procedure, temperature reduces mild, burned product product qualified rate increases.
Namely the kiln cooling chamber that the utility model provides as the salband of ordinary crossing kiln, can go out and as the cooling chamber of split type tunnel cave, can substantially increase the production efficiency of kiln.
