Description
Technical field
The invention discloses a kind of synthetic leather with hot blast controlling functions or dyeing line drying unit.
Background technology
Need to dry in the process of existing synthetic leather, so that the DMF solution of the solvent as polyurethane is dried.And dyeing line also needs to dry in production and processing, solidify to make dye solvent be dried.
At present, the oven dry operation of traditional synthetic leather or dyeing line is all generally adopt tunnel-type hot air dryer, and provides hot blast using coal as the burner of fuel.Along with China is to the continuous attention of environmental protection, the burner of traditional fire coal, by a large amount of sulfur and nitrogen oxides of generation and coal-fired dust, is unfavorable for the protection of environment very much.
For this reason, people wish to adopt more clean natural gas to be used as fuel to burn, produce hot blast, be supplied to tunnel-type hot air dryer, thus carry out the oven dry operation of synthetic leather or dyeing line.But, the existing burner for tunnel-type hot air dryer hot wind supply, when gas-firing, be entrained with naked light in its hot blast produced simultaneously, when this naked light is incorporated into tunnel-type hot air dryer inside by the hot blast of negative pressure, easily the organic gas produced in synthetic leather or dyeing line drying course is lighted, thus produce the perils such as blast.Therefore, be necessary to improve this.
In addition, in prior art, when tunnel-type hot air dryer carries out oven dry operation, hot blast is entered by the air bells cap of tunnel-type hot air dryer, dry the waste gas produced to be discharged from the opposite side position of air bells cap by exhaust blower, but, in actual job, if exhaust blower breaks down, waste gas cannot discharge in time, and hot blast constantly enters in tunnel-type hot air dryer, the temperature caused in tunnel-type hot air dryer is constantly raised, and the organic combustible gas concentration in waste gas constantly raises, security incident that then can be explosion caused, therefore, be necessary to improve this.
Summary of the invention
The object of the invention is the shortcoming and defect existed to overcome prior art, and provide one fuel gas buring to produce hot blast, and naked light can not be carried secretly in the hot blast produced, simultaneously with hot blast controlling functions, dry job safety and the synthetic leather of the high band hot blast controlling functions of heating efficiency or dyeing line drying unit.
For achieving the above object, technical scheme of the present invention includes tunnel-type hot air dryer, for providing the direct-fired gas burner of hot blast, recuperative heat exchanger and hot blast controlling organization to tunnel-type hot air dryer, is provided with hot gas passing away and the air inlet passage of mutual heat exchange in this recuperative heat exchanger;
Described direct-fired gas burner includes burner cavity, this burner cavity include be communicated with successively enter air chamber, combustion chamber and hot blast derive room, described enters the entrance point that air chamber is arranged at combustion chamber, the entrance point of this inner and combustion chamber of entering air chamber is connected, Gas Pipe is provided with in described combustion chamber, in this Gas Pipe, distribution is provided with multiple burner, the outer end that described hot blast derives room is provided with hot-blast outlet, the inner that this hot blast derives room is connected with combustion chamber, and be provided with the spaced bending wind deflector of multiple tracks between the outer end of this hot blast derivation room and the inner, gap between adjacent bending wind deflector forms hot blast derives passage,
Described tunnel-type hot air dryer includes transporting belt and covers at the air bells cap on conveyer belt, air bells cap hot wind inlet and air bells cap hot-blast outlet is provided with in this air bells cap, the hot-blast outlet place that described hot blast derives room is provided with the first air blast be connected with the air bells cap hot wind inlet of tunnel-type hot air dryer, the air bells cap hot-blast outlet of described tunnel-type hot air dryer is connected with exhaust blower, this exhaust blower is connected with the entrance point of the hot gas passing away of recuperative heat exchanger, the import department of the air inlet passage of described recuperative heat exchanger is provided with air blast, the port of export of this air inlet passage is connected with the air bells cap hot wind inlet entering air chamber and tunnel-type hot air dryer of direct-fired gas burner,
Described hot blast controlling organization includes and is arranged at central controller, be arranged at the first pressure sensor of air bells cap hot-blast outlet position, be arranged at the second pressure sensor that hot blast derives the hot-blast outlet position of room, the signal input of this first pressure sensor and the second pressure sensor is connected to central controller, this central controller is provided with actuator, and this actuator is connected with the first air blast and exhaust blower drived control respectively.
By this setting, room is derived by being provided with hot blast in burner, the hot blast that combustion gas produces after the combustion of combustion chamber is derived by bending wind deflector, be entrained in naked light in hot blast then through in the process of bending wind deflector, the shearing wind-force produced because wind direction constantly changes makes naked light extinguish, thus ensure that the hot blast produced from burner does not carry naked light secretly, and then ensure that this hot blast is for the organic combustible gas of drying and producing that can not ignite when artificial leather or dyeing line oven dry, has ensured the safety that equipment runs.By above-mentioned gas burner to the hot blast of tunnel-type hot air dryer supply not with naked light, and dry the heat produced and discard and discharged by the hot gas passing away of recuperative heat exchanger, simultaneously, by the air inlet passage of recuperative heat exchanger, discarded middle exchange heat is come, continue to supply hot-air to tunnel-type hot air dryer supply hot blast and to the air chamber that enters of burner, thus drastically increase heat utilization efficiency, also improve the efficiency of combustion of burner, effects of energy saving and emission reduction is remarkable simultaneously.
In addition, by the hot blast controlling organization of this setting, the first pressure sensor is utilized to detect the blast flowing through air bells cap hot-blast outlet, once blast occurs abnormal, then signal is exported to central controller, by central controller Collaborative Control first air blast and exhaust blower, thus effectively prevent DMF gas concentration in the temperature in tunnel drier and waste gas from constantly raising, ensured that equipment runs safe and reliable.
Further setting be described bending wind deflector by least 4 sections mutually vertically and successively the Direct/Reverse guide plate that bending connects that interlocks be spliced.
By this setting, through facts have proved that the bending wind deflector only having the guide plate of more than 4 sections to form can ensure that the naked light in hot blast can be extinguished, ensure the safety of drying operation.
In sum, advantage of the present invention is: adopt natural gas to burn, supply hot blast, and can not carry naked light secretly in hot blast, dry compared to traditional fire coal, environment protecting is good, and dries safe and reliable, in addition, efficiency of utilization of the present invention is high, and effects of energy saving and emission reduction is remarkable.Also have hot blast controlling functions, equipment safety in operation is good simultaneously.
Below in conjunction with specification drawings and specific embodiments, the present invention is described further.
