The specific embodiment
Below in conjunction with drawings and the specific embodiments the concrete structure that the utility model proposes is further described.
As shown in Figure 2, a kind of monoblock type heat supply purifier 20 that the utility model proposes is arranged at the outside for dried tunnel 21, please cooperate referring to Fig. 3, it has shell body 22, these shell body 22 two ends are respectively equipped with air inlet 23, air outlet 24, also be provided with waste gas inlet 25 on the described shell body, Waste gas outlet 26, above-mentioned air inlet 23, air outlet 24 and waste gas inlet 25 are connected with Drying tunnel 21 respectively.
Be provided with burning in the shell body 22 of heat supply purifier 20 of the present utility model and purify stove 27, this burning purifies stove between described air inlet 23 and air outlet 24, and it is provided with a waste gas inlet 25 and an exhaust outlet 26; Be provided with high-temperature filter 28 near described air outlet 24 places; One end of described shell body 22 is provided with circulating fan 29.
Above-mentioned blower fan 29 is embedded at shell body 22, and its wind drum and impeller place in the shell body 22, and motor 291 is arranged on the outside of shell body 22.Described blower fan 29 can be arranged on the air opening end of shell body 22, shown in Fig. 3,4,5, this heat supply purifier is moved under negative pressure state, reduces gas leakage.When blower fan 29 was arranged at the air opening end of shell body, because heated hot blast need pass the wind drum and the impeller of blower fan, so this blower fan need be selected resistant to elevated temperatures blower fan for use.
Certainly, described blower fan 29 also can be arranged on the air inlet end (not shown) of shell body 22, because the wind-warm syndrome of air inlet end is lower, so this blower fan resistance to elevated temperatures can reduce, thereby can reduce the cost of blower fan.
Shown in Fig. 3,4, described burning purifies stove 27 and is made of burner 271, combustion chamber 272 and heat exchanger 273, and this heat exchanger 273 is near described air inlet 23 end settings, and burner 271 is connected with the burning energy, as being connected with natural gas, coal gas, light oil etc.; Combustion chamber 272 is arranged on the middle part in the utility model shell body 22; Heat exchanger 273 is flat pipe type (or board-like) heat exchanger, and its hot import connects exhaust gas inlet 25, and exhaust outlet 26 is led in the heat outlet, and cold import connects air inlet 23, and air outlet 24 is led in cold outlet.
In drying course, for the quality that guarantees workpiece and the temperature of baker, hot blast adopts the system of an inner loop.Circulated air carries out the hot blast inner loop by blower fan 29 as power, the burner 271 that burning purifies stove 27 adopts diesel oil or natural gas (liquefied gas etc.) as the energy, the elevated temperature heat air-flow that forms, the flat tube (plate) of the heat exchanger of making by stainless sheet steel 273, carrying out heat with the circulated air that enters the utility model air inlet 23 through pipeline by Drying tunnel 21 imitates and changes, to dry the waste gas that produces is simultaneously introduced in the burner hearth 272 through waste gas inlet 25 by Drying tunnel 11, adopt the flame revolving structure, make that organic substance at high temperature resolves into carbon dioxide and water in the waste gas, energy that discharges and high temperature gas flow heat cycles wind, Purge gas after the burning is disposed in the atmosphere by exhaust outlet 26, reaches the purpose that purifies air in heating.High temperature circulation wind after heat exchanger 273 heating filters the back by the high-temperature filter 28 that is arranged on shell body 22 air opening ends and is sent in the Drying tunnel 21 by air outlet 24, thereby has guaranteed the quality of circulated air.Blower fan is become embedded by general pedestal type, wind drum and impeller are placed in the housing, and motor is placed on outside the housing, has promptly reduced noise, has improved the safe running performance of motor simultaneously.Arrow A is depicted as the flow direction of circulated air among Fig. 3,4, and arrow B is the flow direction of harmful exhaust.
All parts of the present utility model all make up and are arranged in the shell body 22, form the integral body that compactness is orderly, and therefore, the utility model has constituted the collection heating and environmental protection is the energy-conserving product of one.
