The course of work of the heating system of the present embodiment synthetic leather wet production line is summarized as follows：Synthetic leather wet production line
Heated by natural gas device 2 starts in start initial stage, baking oven 1, is that baking oven 1 is heated, and the high-temp waste gas that baking oven 1 is discharged is returned into waste heat
Receiving apparatus 31, is the heat-conducting oil heating in the first casing, now because heat conduction oil temperature is relatively low, and first in the first triple valve 42 is led to
(second, third, fourth, fifth, the situation of the 6th triple valve 65 are the same) is closed in road 8, and motor-driven valve 32 is opened, and the first oil pump 33 is opened
Open, conduction oil is in (the first heat-conducting oil pipes of the waste-heat recovery device 31--heat-conducting oil pipes-the of motor-driven valve 32- second of waste heat temperature elevation system 3
The heat-conducting oil pipes of one oil pump 33- the 3rd) middle formation interior circulation so that the heat conduction oil temperature in waste heat temperature elevation system 3 is in high-temp waste gas
Heating under gradually rise.While waste heat temperature elevation system 3 works, pre- hot-rolling temperature elevation system 4, the and of ironing roller temperature elevation system 5
Rinsing bowl temperature elevation system 6 is also in work, because these three system work process are identical, in order to avoid repeating, and just takes pre- hot-rolling liter
The course of work of warm system 4 is illustrated.
As shown in Fig. 2 when the temperature of the conduction oil in waste heat temperature elevation system 3 is also not up to wanting for the pre- operating temperature of hot-rolling 41
When asking, (being to have conduction oil in the heat-conducting oil pipes in pre- hot-rolling temperature elevation system 4), the first electric heater in pre- hot-rolling temperature elevation system 4
44 and second oil pump 43 start, the first triple valve 42 and second channel 9 and third channel 10 in the second triple valve 45 are all
Open, the conduction oil in pre- hot-rolling temperature elevation system 4 is circulated between the first electric heater 44, the oil pump 43 of pre- hot-rolling 41 and second, i.e.,
The conduction oil in conduction oil and waste heat temperature elevation system 3 in pre- hot-rolling temperature elevation system 4 is isolation, and in each affiliated system
It is middle to be heated up (conduction oil in pre- hot-rolling temperature elevation system 4 is by the heat temperature raising of the first electric heater 44).When in waste heat temperature elevation system 3
The temperature of conduction oil when reaching the requirement of the pre- operating temperature of hot-rolling 41, in the first triple valve 42 and the second triple valve 45
One passage 8 is opened, third channel 10 is closed, that is, has been cut off the circulation loop of pre- hot-rolling temperature elevation system 4, simultaneously closed off motor-driven valve
32nd, the first electric heater 44 and the second oil pump 43, that is, cut off the circulation loop of waste heat temperature elevation system 3, and constitute one it is new
Conduction oil in circulation loop (the pre- oil pumps 33 of hot-rolling 41- first of waste-heat recovery device 31-), now former pre- hot-rolling temperature elevation system 4
Mixed with the conduction oil in former waste heat temperature elevation system 3, mixed conduction oil provides heat by the waste gas in exhaust duct 11
Measure to continue to raise temperature.
When temperature needed for the temperature of mixed conduction oil is raised to ironing roller 51 or rinsing bowl 61 works, again by control
Ironing roller temperature elevation system 5 or rinsing bowl temperature elevation system 6 are cut off in the keying of passage in triple valve processed, and by ironing roller 51 or are washed
Groove 61 is accessed in above-mentioned new circulation loop, for example, ironing roller 51 is accessed into above-mentioned new loop, now, and conduction oil has two to follow
Endless path (pre- the first oil pumps of hot-rolling 41- 33 of waste-heat recovery device 31-；Waste-heat recovery device 31- ironing rollers the first oil pumps of 51-
33).It is readily appreciated that, motor-driven valve 32 is the break-make for controlling waste heat temperature elevation system 3, when the heat conduction of waste heat temperature elevation system 3
When oil reaches that pre- hot-rolling 41, ironing roller 51 and the three of rinsing bowl 61 operating temperature of any one need, should all be closed with
Cut-out waste heat temperature elevation system 3 constitutes new circulation loop.
First passage 8, second channel 9 and threeway in first triple valve 42, the 3rd triple valve 52 and the 5th triple valve 62
The open/close states in road 10 there may be difference, and reason is pre- hot-rolling 41, the work temperature of ironing roller 51 and rinsing bowl 61 this three
Degree requires different, i.e., the break time of pre- hot-rolling temperature elevation system 4, ironing roller temperature elevation system 5 and rinsing bowl temperature elevation system 6 can deposit
At interval.
In summary, the heating system for the synthetic leather wet production line that the utility model is provided, it is not necessary to led using fire coal
Hot oil boiler or natural gas heat conducting oil boiler, advantageously reduce production cost；The heat in waste gas is made full use of, without fire coal
Pollution, it is more environmentally friendly；Pre- hot-rolling temperature elevation system, ironing roller temperature elevation system and rinsing bowl temperature elevation system are provided with, waste heat is solved and returns
The problem of receiving time lag；There is no scattering losses and the potential safety hazard of conduction oil long-distance transmissions；Simple in construction, operation is flexible.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalents made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in the technology neck of correlation
Domain, is similarly included in scope of patent protection of the present utility model.
