Abstract
The invention discloses a device for recovering waste heat of a ceramic powder drying tower and intends to recover the heat to be pre-discharged along with vapor at a chimney inlet (2) and heat up theslurry about to enter a drying procedure. A heat-absorption pipeline (3), a heat pump (4) and a heat-transfer pipeline (5) are communicated with a slurry pool (1) at the chimney inlet (2). Accordingly, the heat about to enter a chimney D via the chimney inlet (2) can be absorbed by the heat pump (4) when the heat pump is started, and the heat is further transferred to the slurry pool (1) via theheat-transfer pipeline (5) by the heat pump (4) to directly heat the slurry about to enter the drying procedure. Compared with the normal-temperature slurry, the heated slurry can inevitably reduce the fuel consumption in the drying process and further reduce the drying cost.
Description
Affiliated technical field:
The present invention relates to a kind of waste-heat recovery device, specifically refer to the waste-heat recovery device of ceramic powder drying tower.
Background technology:
The ceramic powder drying tower is with through levigate ceramic tile blank mud, and the high temperature drying of spraying becomes the device of powder, by mud pit, and spraying system, heating system, tower body, the heat extraction chimney constitutes.In order to allow the mud mist become powder at the shortest time inner drying, keep 500～600 ° temperature in the tower body, original moisture is internalized into steam at tower body and drains through chimney in the mud.Chimney is also taken away a large amount of heats in discharge water steam.These heats of desiring pre-discharging are recycled, can be reduced drying cost, reduced energy resource consumption.
Summary of the invention:
The present invention discloses a kind of waste-heat recovery device of ceramic powder drying tower, be intended to that pre-heat with discharge of steam is desired in the chimney porch and reclaimed, heating is about to enter the mud of drying program, reduces the fuel consumption of heating system, energy savings reduces heating cost.
Technical scheme:
The technical solution adopted in the present invention is: insert an end of endothermic tube in the chimney porch, the other end of endothermic tube is connected with the import of heat pump, and the outlet of heat pump connects an end of defeated heat pipe, the straight-through mud pit of the other end of defeated heat pipe.When heat pump started, the heat of desiring pre-discharging was sent heat into mud pit just by the heat pump inspiration by the outlet and the defeated heat pipe of heat pump, and directly heating is about to enter the mud of drying program.Mud through heating must reduce the firing rate of dry run than the mud of normal temperature attitude, and then reduces drying cost.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of ceramic powder drying system;
Fig. 2 is a waste heat recovery schematic diagram of the present invention;
Among the figure 1., mud pit, 2., the chimney porch, 3., heat absorbing conduit, 4., heat pump, 5., heat supply pipeline, A, dry tower body, B, mud spraying system, C, heating system, D, chimney.
The specific embodiment:
In the embodiment in figure 1, ceramic powder drying tower system by mud pit 1., mud spraying system B, tower body A, heating system C, 2. chimney enters the mouth, chimney D constitutes.Powder must be dried to through levigate ceramic tile blank mud and just adobe can be made, mud enters drying tower and is dried to and is introduced into mud pit before the powder and 1. stores, by mud spraying system B with the mud inspiration, nebulize through high-pressure atomization and to spray in the tower body A, keep in the tower body A 500～600 ° temperature by heating system C, at high temperature the moisture in the mud becomes steam, realize water, powder separates, powder falls, 2. water vapour enters chimney D through the chimney porch and is discharged in the atmosphere, also take away a large amount of heats when draining water vapour, chimney porch temperature 2. is between 300～350 ° after tested.
In the embodiment of Fig. 2,2. the chimney porch is connected with an endothermic tube end 3., and the endothermic tube other end 3. then is connected with heat pump import 4., and 5. heat pump outlet 4. is connected with defeated heat pipe, and the straight-through mud pit of the defeated heat pipe other end 5. 1..When 4. heat pump started, the heat that 2. desire enters chimney D by the chimney porch was just by 4. inspiration of heat pump, and 5. 4. heat pump exports sends into defeated heat pipe with heat, and 1. 5. defeated heat pipe send into mud pit with heat, and directly heating is about to enter the mud of drying program.Mud through heating must reduce the firing rate of dry run than the mud of normal temperature attitude, and then reduces drying cost.
Claims (1)
- A kind of ceramic powder drying tower waste-heat recovery device, comprise heat pump, heat absorbing conduit, heat supply pipeline, it is characterized in that: the waste heat that heat pump is desired pre-discharging by heat absorbing conduit with chimney absorbs, and by heat supply pipeline waste heat is directly sent into the mud pit heating and is about to enter the mud of drying tower drying.
