Abstract
The utility model provides an air heat exchanger device which comprises a shell. A thermal insulating layer is arranged on the outer surface of the shell. The two side faces, which form a 180-degree included angle, of the shell are provided with a cold air inlet and a hot air outlet respectively. A partition plate is arranged at the midpoint of the central axis of the cold air inlet and the midpoint of the central axis of the hot air outlet and is perpendicular to the central axes. Multiple columns of stainless steel smoke pipes are arranged side by side in the shell. A smoke discharge pipe is communicated with the upper end of each stainless steel smoke pipe. A regulating valve is arranged on each smoke discharge pipe. By the adoption of the technical scheme, the structure is simple, manufacturing cost and maintenance cost are low, heat absorption efficiency is high, the rising temperature of combustion air is suitable for helping combustion, the burning capacity of natural gas is reduced, and the energy-saving effect is remarkable.
Description
Technical field
The utility model relates to combustion of natural gas heating and energy saving field, is specifically related to a kind of air heat-exchange apparatus.
Background technology
In Fuel Furnace, the fuel that flue gas is taken away is very large.In the main department such as metallurgical, mechanical industrial fuel-fired furnace used, the flue-gas temperature of discharging from body of heater is up to 600 ℃-800 ℃, and its waste of fuel is generally 30-40%.To this, how cost-effective a large amount of high-temperature residual heat resources is is recycled, and has been the main direction of Energy Saving for Industrial Furnace, and Ye Shi enterprise improves energy utilization rate, solve enterprise energy imbalance between supply and demand, reduce production costs, improve the effective way of business efficiency.For many years, the expert in many heat energy field has done a large amount of research work aspect Energy Saving for Industrial Furnace, manage the efficient recycling of heat in the flue gas of discharge, but because cost costliness, complex structure, utilization rate are not satisfactory, do not have completely really to apply to put into practice.The appearance of self-preheating burner, its energy-conservation superiority and perfectly heat exchange structure are to the energy-conservation dawn that brought of combustion of natural gas, however cost is too high, has affected applying of it, can only in the system of some high-end combustion requirements, use once in a while it.
Utility model content
The purpose of this utility model is to overcome the problem that prior art exists, and a kind of simple in structure, low cost of manufacture, the significant air heat-exchange apparatus of heat transfer effect are provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of air heat-exchange apparatus, comprise housing, in described housing outer surface, be provided with heat-insulation layer, at described housing, be on the two sides of 180 ° of distributions and be respectively arranged with cold air air inlet and hot-air air outlet, midpoint vertical centering control axis in the axis of described cold air air inlet and hot-air air outlet arranges a dividing plate, in described enclosure interior, be arranged side by side multiple row stainless steel smoke tracheae, described stainless steel smoke tracheae upper end is communicated with smoke discharge pipe, on described smoke discharge pipe, is provided with damper.
Further, in described housing bottom, base plate is installed, described dividing plate lower end is arranged on described base plate, between described dividing plate upper end and the top board of described housing upper end, is provided with gap.
Preferably, described stainless steel smoke tracheae is thin-wall pipe, and lower end is through the described base plate small end distance that stretches out, and described stainless steel smoke tracheae upper end extends in described smoke discharge pipe through described top board, between described stainless steel smoke tracheae, is provided with circulation of air gap.
The beneficial effects of the utility model are:
Adopt technical solutions of the utility model, air heat exchanger has fully absorbed the heat of high temperature discharge flue gas, improved combustion air temperature, the corresponding heating-up temperature that also improved, simultaneously, effectively improved burning condition, thereby reached the completing combustion of fuel, reduced the quantity combusted of natural gas, energy-saving effect is remarkable, heat exchanger structure is simple, and cost of manufacture and maintenance cost are extremely low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure explanation: 1, housing, 11, base plate, 12, top board, 2, heat-insulation layer, 3, cold air air inlet, 4, hot-air air outlet, 5, dividing plate, 6, stainless steel smoke tracheae, 7, smoke discharge pipe, 8, damper.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1, a kind of air heat-exchange apparatus, comprise housing 1, at described housing 1 outer surface, be provided with heat-insulation layer 2, at described housing 1, be on the two sides of 180 ° of distributions and be respectively arranged with cold air air inlet 3 and hot-air air outlet 4, at described cold air air inlet 3 and the midpoint vertical centering control axis of the axis of hot-air air outlet 4, a dividing plate 5 is set, in described housing 1 inside, be arranged side by side multiple row stainless steel smoke tracheae 6, described stainless steel smoke tracheae 6 upper ends are communicated with smoke discharge pipe 7, on described smoke discharge pipe 7, are provided with damper 8.
Further, in described housing 1 bottom, base plate 11 is installed, described dividing plate 5 lower ends are arranged on described base plate 11, between described dividing plate 5 upper ends and the top board 12 of described housing 1 upper end, are provided with gap.
Preferably, described stainless steel smoke tracheae 6 is thin-wall pipe, and lower end is through the described base plate 11 small end distance that stretches out, and described stainless steel smoke tracheae 6 upper ends extend in described smoke discharge pipe 7 through described top board 12, between described stainless steel smoke tracheae 6, are provided with circulation of air gap.
Principle of the present utility model:
Combustion air is entered by cold air air inlet 3, circulation on one side in Heat Room, absorb stainless steel smoke tracheae 6 tube wall heats on one side, then upwards by dividing plate 5 tops, entering the circulation of Heat Room opposite side, to absorb stainless steel smoke tracheae 6 tube wall heats downward simultaneously again, by hot-air air outlet 4, discharged, as the use of combustion system combustion air.Body of heater high-temperature flue gas through branched stainless steel smoke tracheae 6 upwards, enter smoke discharge pipe 7, the adjustable smoke discharge amount of damper 8 on smoke discharge pipe 7, prolong smoke is in the holdup time of Heat Room, to reach the effect of abundant heat exchange, Fig. 1 arrow is combustion air and flow of flue gas direction, and Heat Room shell heat-insulation layer 2 had been both overcoat, also for preventing the effect of heat loss.
