Compared with the prior art, the waste heat recovery device provided by the utility model is simple in structure, is higher in heat exchange efficiency, runs safely and reliably, has long service life, has high waste heat recycling ratio, and has a much good application prospect.
Description
Technical field
The utility model relates to the printing equipment technical field, especially a kind of waste heat recovery plant for coating machine oven.
Background technology
Current, along with the high speed development of national economy, electric power is as a kind of cleaning, secondary energy sources easily, and disparities between supply and demand day is becoming tight, and energy shortage has become one of significant problem of the world today.Simultaneously, along with increasingly sharpening of inter-industry competition, the control of strengthening manufacturing cost is the important means that enterprise improves profit, dominates the market.Reasonable energy utilization reduces the key subjects that energy consumption is listed in economic development, reduces the requirement that the energy consumption cost is not only society, especially the inherent requirement of enterprise's self-growth and lasting profit.
Coating machine baking oven heating in the coating production process needs to consume a large amount of electric energy, and the EGT that discharges simultaneously is also higher, can reach more than 100 ℃.Therefore, in order to reduce the energy consumption cost of coater oven, research and development have the very energy recovery complexes of high thermal efficiency, as use the RTO power-saving technology on coating machine oven, can produce considerable economic and social benefit.The problem that exists is: the RTO power-saving technology has high input, and return period is longer, and service condition is harsher, and equipment is in operation needs the consumption of electric energy and diesel oil, thereby popularization has certain difficulty.
The utility model content
The purpose of this utility model is a kind of waste heat recovery plant that designs for the deficiencies in the prior art, adopts hot pipe conducting to reclaim the waste hot gas structure, and heat exchanger effectiveness is higher, safe and reliable to operation, long service life, the Waste Heat Recovery utilization rate is higher, has the extraordinary prospect that promotes the use.
The purpose of this utility model is achieved in that a kind of waste heat recovery plant, the heat exchange box and the heat exchanger tube that comprise the peripheral hardware heat-insulation layer, be characterized in that the heat exchange box inner route clapboard is divided into upper heat-exchanging chamber and lower heat-exchanging chamber, several heat exchanger tubes be arranged in heat-exchanging chamber and lower heat-exchanging chamber and with dividing plate for being fixedly connected with; Described upper heat-exchanging chamber and lower heat-exchanging chamber are respectively equipped with new wind import and export and waste hot gas import and export.
Described several heat exchanger tube is that the matrix form arrangement is connected with divider upright.
The utility model compared with prior art has simple in structure, and heat exchanger effectiveness is higher, and is safe and reliable to operation, long service life, and the Waste Heat Recovery utilization rate is higher, has extraordinary popularizing application prospect.

The specific embodiment
Consult accompanying drawing 1, the utility model is comprised of the heat exchange box 1 that is provided with heat-insulation layer outward and heat exchanger tube 2, heat exchange box 1 inner route clapboard 5 is divided into upper heat-exchanging chamber 3 and lower heat-exchanging chamber 7, several heat exchanger tubes 2 be arranged in heat-exchanging chamber 3 and lower heat-exchanging chamber 7 and with dividing plate 5 for being fixedly connected with; Described upper heat-exchanging chamber 3 and lower heat-exchanging chamber 7 are respectively equipped with new wind import and export 4,9 and waste hot gas import and export 8,6.
the utility model is installed and used like this: the coating machine oven air draft access waste hot gas import 8 of 95 ℃ that will reclaim, fresh air access fresh inlet 4, the baking oven air draft of 95 ℃ and the fresh air of environment temperature carry out convective heat exchange by several heat exchanger tubes 2 in heat exchange box 1, heat exchanger tube 2 adopts the aeronautical material with very high heat conductivity to make, in entering lower heat-exchanging chamber 7, the baking oven air drafts of 95 ℃ carry out heat exchange with heat exchanger tube 2, and by heat exchanger tube 2, the heat in lower heat-exchanging chamber 7 is transmitted to rapidly in upper heat-exchanging chamber 3, heat exchanger tube 2 so constantly is transmitted to the heat in lower heat-exchanging chamber 7 rapidly the upper heat-exchanging chamber 3 new wind of heating, new air temperature is raise, the new wind of preheating does not directly contact with the exhaust waste heat of recovery, so new wind can be not contaminated, new wind after preheating can directly be used in coating.The utility model does not have rotatable parts, and not extra consumed energy is safe and reliable to operation, long service life, the temperature drop of body is very little simultaneously, and the heat conductivity of heat pipe is good, almost carries out close to isothermal, thereby heat exchange efficiency is higher, and energy-saving effect is (approximately 30%) significantly, has extraordinary application prospect.
More than just the utility model being further described, is not to limit this patent, and all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
