Description
Technical field
The utility model belongs to technical field of chemical, is specifically related to heat-conducting oil furnace reclamation of stack gas afterheat system.
Background technology
Heat conducting oil boiler is firing equipment conventional in current Chemical Manufacture, and conduction oil serviceability temperature is high, thus causes the gas temperature in flue also very high, when heat conducting oil boiler provides 250
oduring C deep fat, effluent gas temperature reaches 450
oc, and when oil temperature reaches 300
oduring more than C, effluent gas temperature is up to 600
omore than C.But existing manufacturing enterprise is often directly discharged into flue gas in air, cause heat energy loss large, energy waste is serious, and also heat radiation can be caused to affect on surrounding environment.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing Production in Chemical Plant technology adopts heat-conducting oil furnace heating technique, utilize disappearance for existing chemical enterprise conduction oil reclamation of stack gas afterheat or take part Application way but the situation such as recovering effect is not good enough, there is provided a kind of at heat-conducting oil furnace flue gas waste heat spray drying system, utilize flue gas waste heat directly for spray dryer provides required hot-air, thus realize the Collection and utilization to heat energy.
The heat-conducting oil furnace flue gas waste heat spray drying system that the utility model provides, being the gas heat-exchange system flue between heat-conducting oil furnace and chimney arranged for adding hot-air needed for spraying dry, specifically comprising heat-conducting oil furnace, spray dryer, gas heat-exchange system; Described gas heat-exchange system comprises and is successively set on gas stream on passage and interconnective warm-up cycle interchanger and heat exchanger; Described spray dryer import is connected with the hot air outlet of the heat exchanger of gas heat-exchange system, and the air outlet slit place of spray dryer is provided with air-introduced machine.By gas heat-exchange system, the flue gas waste heat in heat-conducting oil furnace is converted into the air heat energy, directly for spray dryer provides hot-air.
As preferably, described warm-up cycle interchanger air intlet place is provided with pressure fan.
As preferably, described gas heat-exchange system also comprises and is arranged on the water film dust removal device of gas stream on passage, and after it is positioned at warm-up cycle interchanger, flue gas temperature after gas-heat exchanger, the heat exchange of warm-up cycle interchanger is reduced to 100
obelow C, now can play water film dedusting effect well, thus reduces the disposal of pollutants of flue gas, has safety and environmental protection effectiveness.
Compared with prior art, the utility model has significant effect: made full use of by the heat of gas heat-exchange system by heat-conducting oil furnace flue gas, directly required air is carried out preheating, heated, for spray dryer provides hot-air, device structure is simple, economize energy, and during flue gas emissions, temperature reduces greatly, has the advantages such as energy-conservation, safety, environmental protection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model conduction oil flue gas waste heat spray drying system.
Number in the figure: 1 is heat-conducting oil furnace, 2 is gas heat-exchange system, and 3 is heat exchanger, and 4 is warm-up cycle interchanger, and 5 is pressure fan, and 6 is water dust scrubber, and 7 is spray dryer, and 8 is air-introduced machine, and 9 is chimney, and 10 is air-introduced machine.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described in further detail.
Embodiment 1
Heat-conducting oil furnace flue gas waste heat spray drying system, see Fig. 1, it comprises heat-conducting oil furnace 1, gas heat-exchange system 2 and spray dryer 7, described gas heat-exchange system 2 is arranged on the flue between heat-conducting oil furnace 1 and chimney 9, and it comprises and is arranged on the warm-up cycle heater of gas stream on passage 4 and heat exchanger 3.By gas heat-exchange system 2 flue gas waste heat directly added hot-air and be supplied to spray dryer 7, thus reaching the recycling of heat energy, economize energy.
Gas heat-exchange system 2 also comprises the water dust scrubber 6 be arranged on flue, after it is positioned at warm-up cycle interchanger.Flue gas temperature after heat exchanger 3 with warm-up cycle interchanger 4 UTILIZATION OF VESIDUAL HEAT IN is reduced to 100
obelow C, now water film dedusting effect is good, greatly reduces the impact of flue gas on surrounding environment.
Warm-up cycle interchanger 4 is connected with pressure fan 5.
Air enters warm-up cycle interchanger 4 through pressure fan 5 and carries out heat exchange with flue gas, flue gas temperature is reduced greatly, then preheated air enters heat exchanger 3 and carries out heat exchange with the high-temperature oil gas that heat-conducting oil furnace 1 produces, obtain required hot-air and be directly supplied to spray dryer, thus achieve the direct utilization of heat-conducting oil furnace flue gas waste heat, device is simple, has effectively saved the energy, has the advantages such as energy-conservation, safety, environmental protection.
