Abstract
The invention discloses a system and a method of utilizing waste heat of tail gas. According to the system and the method disclosed by the invention, the tail gas with the temperature of 55-65 DEG C at an outlet of a bag type induced draft fan is introduced into a hot air furnace, and meanwhile, dust, which is not filtered, in the tail gas is burnt or blown into a pelletizer. The system and the method have the beneficial effects that heat of the tail gas of the bag dust is fully utilized, when a ton of compound fertilizer is prepared, 2kg of coal can be saved, the phenomenon is obvious in winter, and the blast temperature of the hot air furnace is increased to 60 DEG C from 10 DEG C below zero with a difference of 70 DEG C; a middle air blower can be stopped by virtue of cyclic utilization, and the production cost is saved.
Description
Technical field
The present invention relates to a kind of system and method utilizing using waste heat from tail gas.
Background technology
At present, the tail gas that enterprise's finished product cooler cooling produces is all emptying after the process of bag dirt, as shown in Figure 1, EGT reaches about 60 °, exhaust emissions causes environmental pollution serious, and high-temp waste gas directly discharges and causes energy waste, cannot the dust of bag filtration after filtration emptying.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, a kind of system and method utilizing using waste heat from tail gas to be provided, can using waste heat from tail gas to be made full use of, economize energy, reduce environmental pollution.
For achieving the above object, the present invention adopts following technical proposals:
A kind of system utilizing using waste heat from tail gas, comprise sack cleaner, pocket type air-introduced machine and hot-blast stove, described sack cleaner and hot-blast stove lay respectively at the both sides of pocket type air-introduced machine, the outlet of described sack cleaner connects the import of pocket type air-introduced machine by pipeline, the outlet of described pocket type air-introduced machine is connected with the import of hot-blast stove by pipeline.
Utilize a method for said system, the high-temperature tail gas utilizing sack cleaner to obtain is as the thermal source of hot-blast stove.
The tail gas of 55 ~ 65 DEG C of pocket type air-introduced machine outlet passes into hot-blast stove, and meanwhile, the dust do not filtered in tail gas, carries out burning or being blown into comminutor.
The invention has the beneficial effects as follows,
1. make full use of a bag dirt tail gas heat quantity, ton composite fertilizer can reduce coal consumption and reach 2 kilograms, and winter is more obvious, and hot-blast stove blast temperature is increased to 60 DEG C from-10 DEG C, differs 70 DEG C;
2. bag dirt tail gas is entered hot-blast stove to the dust that do not filter of part or burn or be blown into comminutor, can not environmental pollution be caused;
3. recycle an intermediate drum blower fan of can stopping using, save production cost.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of prior art;
Fig. 2 is present system schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
A kind of system utilizing using waste heat from tail gas, as shown in Figure 2, comprise sack cleaner, pocket type air-introduced machine and hot-blast stove, described sack cleaner and hot-blast stove lay respectively at the both sides of pocket type air-introduced machine, the outlet of described sack cleaner connects the import of pocket type air-introduced machine by pipeline, the outlet of described pocket type air-introduced machine is connected with the import of hot-blast stove by pipeline.
Utilize a method for said system, the high-temperature tail gas utilizing sack cleaner to obtain is as the thermal source of hot-blast stove.
The tail gas of 55 ~ 65 DEG C of pocket type air-introduced machine outlet passes into hot-blast stove, and meanwhile, the dust do not filtered in tail gas, carries out burning or being blown into comminutor.
Make full use of a bag dirt tail gas heat quantity, ton composite fertilizer can reduce coal consumption and reach 2 kilograms, and winter, more obviously hot-blast stove blast temperature was increased to 60 DEG C from normal temperature-10 DEG C, differed 70 DEG C; Bag dirt tail gas is entered hot-blast stove to the dust that do not filter of part or burn or be blown into comminutor, can not environmental pollution be caused; Recycle an intermediate drum blower fan of can stopping using, save production cost.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
Claims (3)
