Abstract
The invention relates to a waste gas utilizing method and device of a loose dryer and belongs to the technical field of waste heat recovery of the textile industry. The waste gas utilizing method includes the steps that waste gas exhausted from the top of the loose dryer is led into the waste gas utilizing device, wherein the waste gas utilizing device is composed of hollow heating rollers which are arranged horizontally and rotate around the axes of the heating rollers, and the two ends of each hollow heating roller are provided with an air inlet and an air outlet respectively; and the waste gas utilizing device performs pre-drying on materials entering the loose dryer. By means of the waste gas utilizing method and device, waste gas exhausted out of the loose dryer is fully utilized so that waste heat can be recycled; the technical scheme is simple and feasible, and disassembly and cleaning are convenient; water content of fabric processed through the method and device is low, the drying time of the loose dryer is shortened, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of loose formula dryer exhaust gas utilization method and device, belong to textile industry heat recovery technology field.
Background technology
In dyeing, pine formula dryer is mainly used in the oven dry laking procedure of woven fabric, knitting heavy weave, knitting flimsy material, its mode of heating mainly contains Steam Heating and heat-conducting oil heating two kinds of modes, in the course of work, the EGT of being discharged by its top is generally 140-150 DEG C, because being mingled with the such as impurity of batting, oil and so in waste gas, is not easy to carry out secondary utilization to it, waste gas directly can be drained in air under normal circumstances, dispersed heat causes the waste of the energy.
Summary of the invention
The object of this invention is to provide a kind of loose formula dryer exhaust gas utilization method effectively avoiding energy waste, the present invention provides waste gas utilization device simultaneously.
Loose formula dryer exhaust gas utilization method of the present invention, that the waste gas of being discharged at loose formula dryer top introduces waste gas utilization device, waste gas utilization device is by horizontally, along the hollow heating roll shaft of own axis forming, hollow heating roll shaft two ends offer air inlet and gas outlet respectively, and waste gas utilization device carries out prebake to the fabric entering loose formula dryer.
Wherein, preferred technical scheme is as follows:
The waste gas that described loose formula dryer top is discharged introduces hollow heating roll shaft after being extracted out by blower fan, and waste gas, after hollow heating roll shaft, drains into outward in air.
Described loose formula dryer waste gas utilization device, by horizontally, along the hollow heating roll shaft of own axis forming, hollow heating roll shaft two ends offer air inlet and gas outlet respectively, and air inlet connects the blower fan collecting loose formula dryer top combustion gas.
Described hollow heating roll shaft is fixed in supporting construction, and its installation site is positioned at loose formula dryer inlet side.
The quantity of described hollow heating roll shaft can be chosen according to actual conditions.There is a thermograde in hollow heating roll shaft, the temperature of namely nearest with loose formula dryer hollow heating roll shaft is the highest, minimum with the temperature of loose formula dryer distance hollow heating roll shaft farthest.
Waste gas utilization device of the present invention, its operation principle is: waste gas enters in hollow heating roll shaft by air inlet, heat in waste gas then needs by the mode circulating-heating of heat transfer and thermal convection current the fabric carrying out drying and processing, namely first prebake is carried out to the fabric entering loose formula dryer, alleviate the operating load of follow-up drying plant, improve energy use efficiency, waste gas, after secondary utilizes, is disposed in air by the gas outlet on hollow heating roll shaft.
Beneficial effect of the present invention is as follows:
(1) the present invention takes full advantage of the waste gas that loose formula dryer is arranged outward, and in outer discharge pipe, the temperature of waste gas reduces, and achieves waste heat and re-uses, energy-saving and emission-reduction;
(2) technical scheme simple and feasible, disassembly, cleaning are convenient, and cost is low;
(3) the fabric water content after waste gas utilization device process of the present invention is low, decreases the drying time of loose formula dryer, improves production efficiency.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.
Embodiment
As shown in Fig. 1 ~ 2, loose formula dryer exhaust gas utilization method of the present invention, that the waste gas of being discharged at loose formula dryer 1 top introduces waste gas utilization device, waste gas utilization device is by horizontally, along the hollow heating roll shaft 3 of own axis forming, hollow heating roll shaft 3 two ends offer air inlet 5 and gas outlet 6 respectively, waste gas utilization device carries out prebake to the fabric entering loose formula dryer 1, thus take full advantage of the waste gas of the outer row of loose formula dryer 1, achieve waste heat to re-use, energy-saving and emission-reduction.
The waste gas that described loose formula dryer 1 top is discharged extracts the hollow heating roll shaft 3 of rear introducing out by blower fan 2, and waste gas, after hollow heating roll shaft 3, drains into outward in air.
Described loose formula dryer waste gas utilization device, by horizontally, along the hollow heating roll shaft 3 of own axis forming, hollow heating roll shaft 3 two ends offer air inlet 5 and gas outlet 6 respectively, and air inlet 5 connects the blower fan 2 collecting loose formula dryer 1 top combustion gas.
Described hollow heating roll shaft 3 is fixed in supporting construction 4, and its installation site is positioned at loose formula dryer 1 inlet side.
Waste gas enters in hollow heating roll shaft 3 by air inlet 5, heat in waste gas then needs by the mode circulating-heating of heat transfer and thermal convection current the fabric carrying out drying and processing, namely first prebake is carried out to the fabric entering loose formula dryer 1, alleviate the operating load of follow-up drying plant, improve energy use efficiency, waste gas, after secondary utilizes, is disposed in air by the gas outlet 6 on hollow heating roll shaft 3.
Do not introduce waste gas utilization device in original technique, the moisture content before wet fabric enters loose formula dryer 1 is 36-40%, and after process of the present invention, moisture content is reduced to 15-20%.
Technical solution of the present invention simple and feasible, disassembly, cleaning are convenient, and cost is low; After carrying out UTILIZATION OF VESIDUAL HEAT IN to waste gas, in outer discharge pipe, the temperature of waste gas reduces; Fabric water content after process of the present invention is low, decreases the drying time of loose formula dryer 1, substantially increases working (machining) efficiency.
