Abstract
The invention relates to a coal bar drying device utilizing the fume of a boiler, which comprises a hot-blast furnace which is communicated with a blower, wherein one end of an air outlet pipe is communicated with the hot-blast furnace, the other end of the air outlet pipe is communicated with a drying kiln by a suction fan of the drying kiln, one end of a fume air inlet pipe is communicated withthe air outlet pipe between the hot-blast furnace and the suction fan of the drying kiln, the other end of the fume air inlet pipe is communicated with the boiler by a suction fan of the boiler, and avalve is arranged on the fume air inlet pipe. The coal bar drying device utilizing the fume of the boiler, which is provided by the invention, utilizes the residual heat of the fume of the boiler effectively, saves the combustion coal quantity of the hot-blast furnace, saves energy resources, lowers the production cost and has simple structure and convenient operation; a dedusting suction fan isadopted as the suction fan of the boiler, which can effectively remove dust in the fume and protect the environment.
Description
Technical field
The present invention relates to a kind of drying unit, particularly a kind of coal bar drying device that utilizes boiler smoke.
Background technology
Waste heat is meant industrial enterprise in process of production, the unemployed energy in using energy source equipment, just unnecessary, the discarded energy.According to statistics, the rate of recovery of China's industrial waste heat resource is 33.5% only, and 2/3 the residual heat resources of having an appointment are wasted.The steam boiler flue-gas temperature also is a kind of of residual heat resources up to 150 degree, and still, for the steam boiler flue gas, general what pay attention to is its harm to environment, and its processing is reached directly outer draining in the atmosphere after the discharge standard; The waste heat of these discharged gas fumes is wasted, and does not obtain utilizing.And drying kiln is used in the oven dry of coal rod usually, supplies with high-temperature hot air by coal-fired hot-blast stove in drying kiln, guarantees to dry kiln temperature and dries under the condition about 130 degree, need add fire coal, has wasted the energy, has increased product cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of coal bar drying device that utilizes boiler smoke, and it can utilize boiler smoke oven dry coal rod, has improved energy utilization rate, has saved the energy, has reduced production cost.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of coal bar drying device that utilizes boiler smoke, comprise the hot-blast stove that is communicated with air blast, discharge pipe one end is communicated with hot-blast stove, the discharge pipe other end is communicated with drying kiln by the drying kiln air-introduced machine, flue gas blast pipe one end is communicated with discharge pipe between hot-blast stove and the drying kiln air-introduced machine, and the flue gas blast pipe other end is communicated with boiler by boiler induced-draft fan, and the flue gas blast pipe is provided with valve.
Boiler induced-draft fan is the dedusting air-introduced machine.
A kind of coal bar drying device that utilizes boiler smoke provided by the invention, owing to be communicated with the flue gas blast pipe on the discharge pipe between hot-blast stove and the drying kiln air-introduced machine, the high-temperature boiler flue gas that boiler produces enters the flue gas blast pipe through boiler induced-draft fan, be directed to the drying kiln air-introduced machine again, mix together to enter in the drying kiln with the hot-blast stove high temperature air feed coal rod is dried, effectively utilized the waste heat of boiler smoke, saved the hot-blast stove Coal-fired capacity, saved the energy, reduced production cost, simple in structure, easy to operate; Adopt the dedusting air-introduced machine can effectively remove dust in flue gas, protected environment as boiler induced-draft fan.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes the hot-blast stove 6 that is communicated with air blast 7, discharge pipe 5 one ends are communicated with hot-blast stove 6, discharge pipe 5 other ends are communicated with drying kiln 3 by drying kiln air-introduced machine 4, flue gas blast pipe 2 one ends are communicated with discharge pipe 5 between hot-blast stove 6 and the drying kiln air-introduced machine 4, flue gas blast pipe 2 other ends are communicated with boiler 9 by boiler induced-draft fan 8, and flue gas blast pipe 2 is provided with valve 1.
Boiler induced-draft fan 8 is the dedusting air-introduced machine.
Operation principle of the present invention is as follows
The high-temperature flue gas that boiler 9 is discharged causes flue gas blast pipe 2 by boiler induced-draft fan 8, flue gas is sent to drying kiln air-introduced machine 4 through flue gas blast pipe 2, drying kiln 3 is interior dries the feed coal rod with together entering after the high temperature air of hot-blast stove 6 output mixes, make it to meet the requirement that stove coal rod moisture content is gone in gas making, the gas behind the oven dry coal rod enters atmosphere by the top of drying kiln 3.
The dedusting air-introduced machine not only has dedusting function but also have the function of air inducing, has protected environment.
