Description
Technical field
The invention belongs to power environment protection field of energy-saving technology, and in particular to a kind of waste heat recovery pulp water cooling system.
Background technology
Water-cooled dreg removing system is the deslagging technique of coal-fired boiler in power plant application for many years.50~seventies of 20th century, power plant
Requirement for environmental protection is not strict, and water resource is also very sufficient, thus the defeated slag of power plant mainly uses hydraulic discharged slag system, periphery
Storage lime-ash place will be typically set, and water resource is not also recycled, and power consumption water consumption is big.From 1980s, power plant
Slag removing system mainly uses the equipment such as Pulp pump, drainage bin for the water sluice technology of main body, its subject matter be system complex,
Floor space is big, high energy consumption, maintenance are big etc..To the latter stage nineties, the introduction with large-scale water immersion type scraping board slag conveyor disappears
Change and application so that the pulp water circulatory system is changed into low capacity from Large Copacity intermitten service and continuously run, and above mentioned problem is obtained
It is effectively improved.Simultaneously in order to avoid water resource is wasted and reduced sewage discharge, slagging-off cooling water need to clarify cooling Posterior circle
Use, power plant will also build the water processing establishment matched therewith.At present, this system is applied to big-and-middle-sized solid also widely
In the water-cooled dreg removing system of state deslagging coal-powder boiler.
Bottom slag is the product that coal dust burns in boiler furnace, and the temperature of bottom slag is typically about 900 DEG C or so, from
It is cold, it is necessary to which substantial amounts of cooling water is cooled down and is granulated to it during falling on submerged slag conveyor under the outlet of boiler furnace hopper
But water is absorbed after the heat of bottom slag, and temperature is increased to 60 DEG C or so.
At present, the water-cooled mechanical deslagging system of domestic and international big-and-middle-sized power plant, which mostly uses, has pulp water to handle recycling
Circular flow mode.High temperature furnace slag is fallen into dragveyer tank by slag-drip opening, then through submerged slag conveyor by the stove after water cooling
Slag scrapes dirt-excluding groove, is delivered to slag storehouse, and slag is transported to by the slag car.In the process to ensure that water temperature is relatively low in tank, dragveyer water
Groove has a large amount of moisturizings, tank is in overflow situation all the time, and the overflow water of slag inclusion enters overflow pond through trench, pumped with slurry
To high-efficiency concentrator (or multistage depositing reservoir) clarification, natural cooling, or force after cooling again by pumped back dragveyer water inlet, weight
Use again.The water taken away during evaporation/vaporization loss water and defeated slag during cold slag with slag is supplemented by system water supplement mouthful, whole
Individual water system is substantially at a continuous dynamic balance state.
The slag removing system of existing closed cycle cooling, operation is complicated, water consumption is big, thermal loss is big, high-efficiency concentrator
Deng equipment energy consumption is high, line clogging is serious, maintenance workload is big.
As the important accessory system of power plant, energy-saving and emission-reduction how are realized, simplifies submerged slag conveyor slag removing system, subtracts
The consumption of few cold pulp water, while reclaiming the heat of cold pulp water just turns into the emphasis direction of industry research.
