Abstract
The utility model belongs to the metal smelting field, concretely relates to supporting waste heat boiler water pump's of ore stove cooling system, the import of cooling water circulating pump is connected to boiler water pump cooling unit delivery port, and the exit linkage of cooling water circulating pump is to boiler water pump cooling unit water inlet, and the cooling water forms the circulation water route between boiler water pump cooling unit and cooling water circulating pump, carry out the heat exchange between circulation and the smelting plant smelt circulating water system. Above-mentioned scheme, smelt the cooling unit that the circulating water does not directly get into the boiler water pump, but carry out the heat exchange between the closed circulation loop with the cooling unit, after the cooling water absorbed the heat of boiler water pump, the transmission gives the circulating water of smelting, the cooling of boiler water pump has both been realized, the relatively poor smelting circulating water of quality of water has been kept apart again and the influence of boiler water pump has been avoided the harm of water pump cooling unit scale deposit, jam, the safe operation of boiler water pump has been guaranteed, and the cooling water recycle of cooling unit, the water resource has been practiced thrift.
Description
Technical Field
The utility model belongs to the metal smelting field, concretely relates to cooling system of supporting waste heat boiler water pump of ore stove.
Background
The waste heat boiler of the Olympic furnace is used for matching with the copper smelting process flow, recovers the waste heat of the flue gas of the Olympic furnace smelting furnace and generates high-pressure saturated steam. The exhaust-heat boiler is usually equipped with several high-pressure electric water pumps, such as an Olympic boiler of the King-Tou copper division of the nonferrous metals group of Tongling, which generates saturated steam with a pressure of about 6.0MPa, and 2Q-2000 m exhaust-heat boilers3KSB high-pressure electric circulating pump and 2Q-96 m3KSB high pressure motor-driven feed water pump of/h.
The electric circulating pump and the electric water-feeding pump (called as waste heat boiler water pump for short) are influenced by heat of the waste heat boiler, the temperature is very high, in order to ensure normal operation, the waste heat boiler water pump needs to be cooled by cooling water in the using process, and the cooling water is from smelting circulating water arranged in a high-level water tank of a main workshop.
Because above-mentioned boiler electric circulating pump and electric feed pump all purchase in Germany import equipment, cooling unit inner structure is more accurate, and it is reuse to smelt the circulating water, and quality of water is relatively poor, and wherein turbidity, calcium ion content are higher, easily cause the inside scale deposit of water pump cooling system, and the heat exchange tube blocks up, brings serious hidden danger for boiler water pump safe operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cooling system of supporting waste heat boiler water pump of ore stove avoids the smelting plant to smelt the inside scale deposit of water pump cooling system, the jam that the circulating water caused because quality of water is poor.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a cooling system of supporting waste heat boiler water pump of ore stove, the import of cooling water circulating pump is connected to boiler water pump cooling unit delivery port, and the exit linkage of cooling water circulating pump is to boiler water pump cooling unit water inlet, and the cooling water forms the circulation water route between boiler water pump cooling unit and cooling water circulating pump, carry out the heat exchange between circulation and the smelter smelting circulating water system.
By adopting the scheme, the cooling medium of the boiler water pump forms a closed circulation loop through the cooling water circulating pump, the smelting circulating water does not directly enter the cooling unit of the boiler water pump, but exchanges heat with the closed circulation loop of the cooling unit, and after the cooling water absorbs the heat of the boiler water pump, the heat is transmitted to the smelting circulating water, so that the cooling of the boiler water pump is realized, the influence of the smelting circulating water with poor water quality on the boiler water pump is also isolated, the scaling and blockage hazards of the cooling unit of the water pump are avoided, the safe operation of the boiler water pump is ensured, the cooling water of the cooling unit is recycled, and the water resource is saved.
Drawings
Fig. 1 is a schematic view of the present invention.
In the figure: 10-boiler water pump cooling unit, 11-cooling unit water inlet, 12-cooling unit water outlet, 20-cooling water circulating pump, 30-desalting water tank and 40-plate heat exchanger
Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings.
The utility model provides a cooling system of supporting waste heat boiler water pump of ore stove, the import of cooling water circulating pump 20 is connected to boiler water pump cooling unit 10 delivery port 12, and the exit linkage of cooling water circulating pump 20 is to boiler water pump cooling unit 10 water inlet 11, and the cooling water forms the circulation water route between boiler water pump cooling unit 10 and cooling water circulating pump 20, carry out the heat exchange between circulation water route and the smelting plant smelting circulating water system.
Preferably, a demineralized water tank 30 is arranged between the water outlet 12 of the boiler water pump cooling unit 10 and the inlet of the cooling water circulating pump 20. The demineralized water is adopted as a cooling medium of the boiler water pump, scaling of a boiler cooling system after long-time operation is avoided, the cost is low, and the demineralized water can be supplemented to the system according to the water level change of the set demineralized water tank.
Preferably, the water pipe of the circulating water path exchanges heat with the water pipe of the smelting circulating water system of the smelting plant. And the water pipe of the circulating water path exchanges heat with the water pipe of the smelting circulating water system of the smelting plant through the plate heat exchanger 40. Of course, other means of heat exchange may be used, such as heat exchange between the water pipe of the smelt circulation water system and the demineralized water tank, etc.
