Abstract
The utility model discloses waste heat utilization equipment for a circulating water system of a calcinator. The waste heat utilization equipment comprises a workshop backwater pool, a heat exchanger and a domestic water tank, wherein the workshop backwater pool and the water outflow end of the domestic water tank are connected with the heat exchanger through pipelines, and water pumps are mounted on the pipelines; and the domestic water outlet of the heat exchanger is connected with the domestic water tank through a pipeline, and the workshop backwater outlet of the heat exchanger is connected with a cold water pool through a pipeline. The waste heat utilization equipment makes the best use of waste heat of circulating water of the calcinator to achieve the energy-saving and emission-reducing purposes.
Description
Technical field
The utility model relates to a kind of waste heat utilization equipment, relates in particular to a kind of calcining furnace circulation waste heat utilization equipment.
Background technology
Along with the fast development of economy, people are increasing to the demand of aluminium, and the carbon element industry is as the consumption goods and materials of electrolytic aluminium, and its output also improves in a large number, so the production capacity of calcining furnace is increasing.After the calcining furnace waste heat satisfies process requirements, also have very large heat well not utilize, caused a large amount of high-grade energies to discharge in vain, so neither environmental protection does not meet again current national to the requirement of energy-saving and emission-reduction.
The calcining furnace UTILIZATION OF VESIDUAL HEAT IN mainly is to utilize the calcining furnace fume afterheat at present, and calcining furnace circulation waste heat does not have fine utilization, causes the amount of heat waste.
The utility model content
The utility model is exactly the problem that exists for prior art, and a kind of calcining furnace circulation waste heat utilization equipment is provided.
Above-mentioned purpose realizes by following proposal:
A kind of calcining furnace circulation waste heat utilization equipment is characterized in that described waste heat utilization equipment comprises workshop back pool, heat exchanger and domestic water tank; The water side of described workshop back pool and described domestic water tank all is connected to described heat exchanger by pipeline, and on pipeline water pump is installed all; The domestic water delivery port of described heat exchanger is connected to the domestic water tank by pipeline, and the workshop backwater delivery port of described heat exchanger is connected to water cooling pond by pipeline.
Waste heat utilization equipment according to above-mentioned is characterized in that, the workshop backwater delivery port of described heat exchanger also is connected to cooling tower by pipeline, and this cooling tower is connected to described cooling pond.
The beneficial effects of the utility model: the utility model takes full advantage of the calcining furnace circulating water afterheat, can reach the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, calcining furnace circulation waste heat utilization equipment of the present utility model comprises workshop back pool 1, heat exchanger 10 and domestic water tank 8.Workshop back pool 1 all is connected to heat exchanger 10 by pipeline with the water side of domestic water tank 8, and the pipeline that leads to heat exchanger 10 at workshop back pool 1 has been installed in parallel two water pumps 2,3, and the pipeline that leads to heat exchanger 10 at domestic water tank 8 is equipped with water pump 9.The domestic water delivery port of heat exchanger 10 is connected to domestic water tank 8 by pipeline, and the workshop backwater delivery port of heat exchanger 10 is connected to water cooling pond 11 by pipeline.The workshop backwater delivery port of heat exchanger 10 can also be connected to cooling tower 4 by pipeline, and cooling tower 4 is connected to cooling pond 11.
The operation process of this equipment is as follows:
The high-temperature workshop backwater is stored in the workshop back pool 1, under the effect of water pump 2 and 3, enter heat exchanger 8, cold water in the domestic water tank 8 enters heat exchanger 8 under the effect of water pump 9, hot and cold water carries out heat exchange in heat exchanger 8, the workshop backwater that is cooled can directly enter cooling pond 11 or store first and enter cooling pond 11 in the cooling tower 4 again.Straight-through pipeline 16 can be set directly connect workshop back pool 1 and cooling pond 11 or cooling tower 4, its effect is the regulating system flow, keeps circulation Inlet and outlet water balance.Water returns workshop continuation use by water pump 5,6 in the cooling pond 11.Heated domestic water turns back to the domestic water tank 8 from heat exchanger 8, by water pump 7 for life.
Claims (2)
