Description
Technical field
The utility model relates to energy-conserving and environment-protective field, particularly relates to a kind of waste-heat recovery device.
Background technology
The recovery of residual heat resources, is conducive to energy consumption equipment and improves efficiency of energy utilization, reduces the discharge of harmful substance, not only economize energy, but also protection of the environment.At present, developed country's industrial energy consumption generally accounts for about 34% of total energy consumption, and China is up to 70%.Major product specific energy consumption average specific international most advanced level is high by 40%.Wherein the recovery utilization rate of industrial exhaust heat is lower is one of major reason that energy consumption is higher, therefore, strengthens waste heat recovery work and has great strategic importance to energy-saving and cost-reducing and environmental protection.According to statistics, domestic industry waste heat total resources account for 17% ~ 67% of fuel consumption total amount.At smelting industry, in, low-temperature flue gas waste heat accounts for the only about half of of fume afterheat resource, as long as adopt the retracting device be suitable for, wherein major part can be recycled.In, the material of low-temperature flue gas heat exchanger is less demanding, be more suitable for adopting air heat exchanger warm-up combustion-supporting air and gaseous fuel, directly the waste heat of recovery be used for stove, improve efficiency of energy utilization.Reduce enterprise's production cost, alleviate problem of environmental pollution simultaneously.
Summary of the invention
The utility model, in order to overcome deficiency of the prior art, provides a kind of waste-heat recovery device.
The utility model is achieved through the following technical solutions:
A kind of waste-heat recovery device, comprise the body of heater with charge door, described body of heater is connected with casing by admission line, described admission line is arranged on the bottom on the left of casing, and admission line passes into thermal cycle district, flows through gas-permeable nets, described gas-permeable nets is provided with water tank by pillar, flue gas flows through the surrounding feed-tank heating of water tank, and the top of described casing is provided with escape pipe, and the gas outlet place of described escape pipe is provided with screen pack.
As optimal technical scheme of the present utility model, described admission line is provided with gas gauge.
As optimal technical scheme of the present utility model, the two ends, left and right of described water tank are close on cabinet wall, are provided with water inlet pipe in the left upper portion of water tank, are provided with outlet pipe in the lower right side of water tank.
As optimal technical scheme of the present utility model, described gas-permeable nets is evenly distributed with air-vent.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, can extensively promote, equipment funds drop into little, and tubular heat exchanger of comparing, flows through water tank surrounding by flue gas, water in heating water tank, improves the utilization rate of flue gas heat, economize energy.
