Abstract
The utility model belongs to the field of energy conservation and exhaust reduction in production of the cold-stamping industry. The afterheat recycling device comprises an exhausting pipeline connected with a hot wind exhausting opening of an air compressor and a ventilating valve and a hot wind outlet arranged in the exhausting pipeline, and the exhausting pipeline is 10-50 m long. Compared with the prior art, the utility model has the advantages that: the afterheat recycling device recycles the heat energy which is wasted initially, increases the utilization rate of the energy, reduces the production cost and protects the environment; the heat exchange efficiency is as high as 88%; the heat taken by the air exhausted from the hot wind outlet is only 10-15% of the initial heat; the machine room can be observed at any time; the hot wind exhausting pipeline is a little hot and does not cause inconvenience, and the flowers and grass outside the window are alive completely. The afterheat recycling device is better than the exhausting fan which is only driven by an air compressor.
Description
Technical field
The utility model belongs to when using pressurized air in the energy-saving and emission-reduction field in the cold stamping industry production process, particularly stamping part course of working, and the heat recovery that air compressor produces utilizes the field again.
Background technique
Energy-conservation and environmental protection is the important topic that the current whole world is paid close attention to, and energy saving, raising energy utilization rate are classified fundamental state policy as in national Eleventh Five-Year Plan outline.Reach the environmental protection demand, improve the energy utilization, reduce CO
2Discharging is private enterprise's obligation one can't decline.Energy-conservation concerning enterprise, the most direct income is exactly the cost saving expenditure, increases economic efficiency, and enhances one's market competitiveness.
In the punch process production process, the air compression chance produces the waste gas that has certain heat, will directly discharge outdoor to keep room temperatur working environment and cleaning by the ventilating fan that air compressor drives usually." waste gas " (delivery temperature reaches about 100 ℃) that has a large amount of heat energy directly discharged, and both wastes energy, again befouling environment; And effect is bad: temperature is high in the compressor house, and the ventilating fan opposite personnel can't stop, and flowers and plants are withered around the ventilating fan, and hot air fills the air.
The model utility content
The utility model aims to provide a kind of waste heat recovering device, with the problem of heat recovery in the waste gas that produces in the solution punch process production process and waste gas cooling discharging.
Waste heat recovering device is characterized in that, comprises the exhaust duct that is connected with the hot blast exhaust port of air compressor and the scavenging air valve and the hot-air outlet that are located in the exhaust duct, and described exhaust duct length is 10 meters～50 meters.
Compared with prior art, the beneficial effects of the utility model are: the energy recovery that will slattern originally, improve energy utilization rate, and reduce production costs the protection environment; Heat exchange efficiency can reach more than 88%, and the heat of taking out of from the gas of hot-air outlet discharge only is original 10-15%, and machine room can enter observation at any time, removes near the hot type airduct road and slightly feels low-grade fever, there is no discomfort, and flowers and plants also survive fully outside window.This is that single ventilating fan with the air compressor drive is incomparable.
Description of drawings
Fig. 1 is the utility model structural representation, wherein, and 1 air compressor, 2 exhaust ducts, 3 scavenging air valves, 4 supports, 5 hot-air outlets.
Embodiment
As shown in Figure 1: waste heat recovering device comprises the exhaust duct 2 and the scavenging air valve 3 that is located in the exhaust duct, for example unidirectional opening the door that are connected with the hot blast exhaust port of air compressor 1, so that hot blast only goes out not return, with hot-air outlet 5, so that hot blast is gone out heat radiation on the way at each Duan Junneng of pipeline; Described exhaust duct length is 10 meters～50 meters (30 meters for best).
Described exhaust duct adopts the made that is easy to dispel the heat, as galvanized iron.
Described exhaust duct is fixed on the indoor wall or the roof by support 4.
Described exhaust duct outlet is led to outdoor or the next door is indoor.
Described hot-air outlet 5 is provided with venetian blind.
0.2～0.7 meter of described exhaust duct diameter, best 0.5 meter of diameter.
During this device operation, high temperature gas flow is discharged from hot-air outlet under the blower fan continuous operation effect, flows along channel direction, and tube wall also dispels the heat simultaneously.
Hot-air outlet institute is to preparation room indoor air temperature rising (the heating phase 4 months winters can be risen 2-3 ℃).The hot air that continues to flow conducts to the punching press scene, makes the also rising (the heating phase 4 months winters can be risen 1-2 ℃) gradually of punching press scene temperature.
The benefit of waste heat recovering device:
1, safety reliability height: it is in line that conventional heat radiation mostly is ventilating fan, makes the interior temperature of compressor house high, influences the maintenance personnel and observe, and its temperature degree reaches about 100 ℃ during compressor operating, and some position becomes awfully hot, scalds easily.
2, this heat recovery then is a secondary heat exchange, and promptly hot-fluid will could conduct by the tube wall of heat pipe hot-blast outlet, even and make somebody a mere figurehead installation and have leakage also to worry about nothing.Heat pipe waste heat recovering device heat transfer efficiency height is 0.5X0.5m sectional area exhaust duct, and very approaching with Compressor Discharge Pressure 0.75Mpa, delivery temperature remains at more than 75 ℃.
3, this waste heat recovering device has good anti-corrosion capability, long service life, and tubing is galvanized iron (SGC), can prevent the dew point humidity corrosion, working life, the single-unit heat pipe was detachably changed more than 10 years, safeguarded simple.
4, installation and structural configuration are flexible: the installation of heat pipe heat recovery need not to change former air compressor system, and the location arrangements of structural design is very flexible, can adapt to various punching presses place.
5, turnover weak point, the return rate height: general six months to 1 year is recyclable fully invested.(3000 yuan of flat cost meters are installed first, and preparation room is economized and purchased 1 7000 yuan in 5 air-conditionings then) be 5 air conditioners of job shop then, save 1800 yuan of the electricity charge (1 yuan/degree of the industrial electricity charge), comprehensive benefit first meeting because of 1-2 ℃ of room temperature rising reduces the available machine time.
6, heat energy utilizes and widens the research and development thinking, and low carbon emission reduction reaches environmental protection, and working environment improves.
