Description
Technical field
This utility model is related to a kind of dragveyer, particularly a kind of pulp water inner-cooled New type wet dragveyer.
Background technology
Large coal-fired power plant boiler wet-type dragveyer is typically both designed as high temperature sludge water through plate type heat exchanger both at home and abroad at present
Cooling Posterior circle utilizes, and design dragveyer pulp water runs water temperature and controls below 60 DEG C, but in actual motion, plate type heat exchanger blocks up
Plug is serious, often cannot normally run.If the method for operation cooling down without plate type heat exchanger using pulp water, can cause to drag for slag
Machine pulp water is between 70 DEG C ~ 90 DEG C for a long time, dragveyer is damaged larger.Conventional dragveyer water supplementing method is mostly manual
Or electric throttling adjustment, not only energy consumption is big for this mode, and dragveyer moisturizing uncontrolled can be directly entered dragveyer pulp water
, easily dragveyer body and buffer tank insufficient water or spilling water phenomenon in system.Pulp water in existing dragveyer system returns
The equipment operation failure rates such as water pump, pulp water circulating pump are high, and the pump housing, water wheels and Incrustation of pipe are very serious, cause extra work in a large number
Make.
Content of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of structure simple, slag water temperature controls effect
Really good, realize dragveyer body pulp water, water seal water level automatically controls, do not produce manufacturability waste water, do not occur waste water excessive, energy-conservation
Emission reduction effect is notable, avoids the pulp water inner-cooled New type wet dragveyer of equipment and channel interior fouling simultaneously.
For reaching above-mentioned purpose, this utility model be employed technical scheme comprise that：A kind of pulp water inner-cooled New type wet drags for slag
Machine, comprises slag well, dragveyer body, slag water cooler, pulp water water-replenishing control device, water seal water-level control apparatus, and its feature exists
In：Described slag down-hole portion is immersed in the pulp water of dragveyer body, described slag well located at burner hearth bottom, described burner hearth and slag well it
Between be provided with furnace bottom water seal, described dragveyer internal body is fixed with slag water cooler, and described slag water cooler and cooler return
Water valve, cooler carry out water valve and are connected, and described dragveyer engine body exterior is provided with pulp water water-replenishing control device, and described pulp water moisturizing controls
Device is connected with Waste water valve, is provided with water seal water-level control apparatus, described water seal water lev el control outside described furnace bottom water seal
Device is connected with water seal water replenishing sectional door, and described water seal water replenishing sectional door is connected with Waste water valve, described Waste water valve with
Power plant process waste pipe connects.
Further, described dragveyer internal body is provided with slag water cooler, and dragveyer body and furnace bottom water seal are respectively
Pulp water water-replenishing control device and water seal water-level control apparatus are installed, you can realize cooling and pulp water, stove in dragveyer body pulp water
Bottom seal water level automatically controls.
Further, described pulp water water-replenishing control device can achieve that the automatic water supplement of dragveyer body pulp water controls, and is setting
During received shipment row, when pulp water water level is low, open moisturizing, close moisturizing when pulp water water level is high, be provided simultaneously with high-low water alarm function,
Guarantee pulp water stable level.
Further, described water seal water-level control apparatus can achieve that water seal consumes the instant supply of water, in the equipment runtime
Between maintain water seal constant level in a reliable water level operation, low water level alarm is it is ensured that pulp water, furnace bottom in dragveyer body
Water seal water level automatically controls.
This utility model advantage has：
1. structure is simple, and dragveyer pulp water runs water temperature and controls below 60 DEG C；
2. solve the problems, such as that pulp water blood circulation water pump, pipeline, valve scaling are serious, frequently keep in repair；
3. achieve dragveyer body water level and water seal water level automatically controls, dragveyer operating repairs and combustion adjustment
Workload declines more than 90%；
4. the safe and reliable level of dragveyer equipment is greatly improved, is that boiler safety stable operation provides Reliable guarantee；
5. by the use of power plant process waste water as dragveyer body, water seal water replenishing, do not produce manufacturability waste water, waste water does not occur
Excessive event, realizes wastewater utilization, simultaneously the equipment such as stoppage in transit pulp water circulating pump, back water pump, and synthetic energy-saving discharge-reducing effect is bright
Aobvious, the upgrading potentiation of power-assisted enterprise.
