Abstract
The utility model discloses a system for utilizing waste heat of waste smoke of a boiler. The system comprises a waste smoke pipeline on the boiler, wherein the waste smoke pipeline is connected with a primary dust remover and a secondary dust remover; the rear part of the secondary dust remover is connected with a fan; a three-way valve is arranged on the fan; and another two ports of the three-way valve are communicated with a chimney and a hot air collecting pipe respectively. The waste smoke discharged by the boiler is subjected to two-level dust removal by the primary dust remover and the secondary dust remover, and dust ash and harmful substances in the waste smoke are filtered out completely, so the dust removing effect is good. Hot air subjected to dust removal is provided for a drying system through a drying fan and a hot air output pipe behind the drying fan for drying of the fiber plate production line, so that energy is saved, the production cost is reduced, the utilization ratio of fuel is increased, environmental projection is promoted, and environmental pollution is reduced.
Description
Technical field
The utility model belongs to waste heat utilization equipment technical field in charcoal element production process, particularly the useless cigarette bootstrap system of a kind of boiler.
Background technology
China is the serious deficient developing country of populous a, resource, and coal has become China's one of resource of shortage the most.
In the carbon industry production process, boiler oil mostly is coal or electric energy, if coal fuel burn incompletely can discharge a large amount of dust ash content and toxic gas, not only atmosphere pollution, also waste energy, and energy utilization rate is low.Now, emerge various UTILIZATION OF VESIDUAL HEAT IN technology in all trades and professions, UTILIZATION OF VESIDUAL HEAT IN is mainly by improving process structure and increase the waste heat that energy saver produces in production process with utilizing of amplitude peak, improving energy utilization rate.Yet because present UTILIZATION OF VESIDUAL HEAT IN engineering one-time investment is higher, Some Enterprises UTILIZATION OF VESIDUAL HEAT IN engineering does not also attain full development, and especially medium-sized and small enterprises, so just limited to popularization and the application of UTILIZATION OF VESIDUAL HEAT IN technology greatly.
The utility model content
The purpose of this utility model be to provide a kind ofly be convenient to implement, utilization rate of waste heat is high and can effectively reduce the useless cigarette bootstrap system of boiler of environmental pollution.
For achieving the above object, the technical solution of the utility model is: a kind of boiler cigarette bootstrap system that gives up, comprise the useless smoke pipeline on boiler, useless smoke pipeline is connected with primary dust removing device and secondary ash collector, the secondary ash collector rear portion is connected to blower fan, blower fan is provided with triple valve, and another two ports of triple valve are connected with chimney and hot blast collecting pipe respectively.
Described hot blast collecting pipe end is connected with drying air fan, and the drying air fan outlet is provided with the hot blast output channel.
Be provided with the dust collection bucket below described primary dust removing device and secondary ash collector.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises the useless smoke pipeline on boiler, useless smoke pipeline is connected with primary dust removing device and secondary ash collector, the secondary ash collector rear portion is connected to blower fan, blower fan is provided with triple valve, another two ports of triple valve are connected with chimney and hot blast collecting pipe respectively, utilize primary dust removing device and secondary ash collector to carry out the two-stage dedusting to the useless cigarette of boiler emission, dust ash content and noxious material in useless cigarette are fully filtered out, good dedusting effect, hot blast through dust removal process offers drying system by drying air fan and subsequent hot blast output channel, utilize for the fibreboard production line oven dry, energy savings not only, reduce production costs, improve fuel availability, also help protection of the environment, reduce environmental pollution.
2, the end at the hot blast collecting pipe is connected with drying air fan, and the outlet of drying air fan is provided with the hot blast output channel, and the hot blast output channel directly leads to the position that needs use hot blast, both has been conducive to improve hot blast utilization rate and hot blast intensity, is convenient to again the hot blast utilization.
3, be provided with the dust collection bucket below primary dust removing device and secondary ash collector, be convenient to clear up the dust ash content of collection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The cigarette bootstrap system that gives up of boiler as shown in Figure 1, it comprises the useless smoke pipeline 2 on boiler 1, is connected with primary dust removing device 3 and secondary ash collector 4 at the end of useless smoke pipeline 2, is connected by smoke pipe 5 between primary dust removing device 3 and secondary ash collector 4.Exit, rear portion at secondary ash collector 4 is connected with blower fan 6 by airduct 13, and the exit of blower fan 6 is connected with triple valve 7, and another two ports of triple valve 7 are connected with chimney 8 and hot blast collecting pipe 9 respectively.In order to improve hot blast utilization rate and hot blast intensity, be connected with drying air fan 10 at the end of hot blast collecting pipe 9, the outlet of drying air fan 10 is provided with hot blast output channel 11, and hot blast output channel 11 directly leads to the position that needs use hot blast.
Dust ash content for the ease of cleaning is collected is provided with dust collection bucket 12 below primary dust removing device 3 and secondary ash collector 4.
Operation principle of the present utility model is: utilize the useless cigarette of 4 pairs of boilers of primary dust removing device 3 and secondary ash collector, 1 discharging to carry out the two-stage dedusting, dust ash content and noxious material in useless cigarette are fully filtered out, good dedusting effect, the hot blast that passes through dust removal process offers drying system or passes through chimney discharged to the external world by drying air fan 10 and subsequent hot blast output channel 11.When drying system is worked, the valve closing that will be connected with chimney 8, with the valve open that hot blast collecting pipe 9 is connected, make hot blast only to the 11 directions circulations of hot blast output channel; When drying system quits work, the valve open that will be connected with chimney 8, with the valve closing that hot blast collecting pipe 9 is connected, make hot blast only to chimney 8 directions circulations.
