Technical field
The utility model relates to paint industry drying system technical fields, and in particular to a kind of Two-way Cycle drying system.
Background technique
Orthodox car drying system is generally divided into two types, and one is drying room heat supply is connected between independent burning heater box
+ RTO handles the mode of exhaust gas, and one kind be that drying room heat supply+waste gas combustion furnace natural gas that burns is connected between heat exchange case is hot
Source handles the mode of exhaust gas simultaneously.Since the exhaust gas after burning is unholiness, it cannot be passed directly into drying room and be directly heated,
So both of which is all that heat source and drying room carry out indirect heat exchange, response speed is slower, and temperature control is unstable；Simultaneously because indirectly
Heat exchange needs heat exchanger, and each region will dispose heat exchanger, and occupation area of equipment is big, and heat dissipation capacity is also relatively large.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of Two-way Cycle drying system
System enhances system stability to improve responding ability.
It is for technical solution used by realization the purpose of this utility model:
A kind of Two-way Cycle drying system, including waste gas combustion furnace, for providing the center of high-temperature gas to region drying room
Heat exchanger and for region drying room provide heating after fresh air fresh air heat exchanger, the high-temperature flue gas of the waste gas combustion furnace
Discharge pipe is successively passed through in the central heat exchanger and fresh air heat exchanger, with to the central heat exchanger and new air heat-exchange
Device provides heat exchange thermal energy；
The central heat exchanger by hot-gas channel with and connect the branch with mixing valve of the hot-gas channel
The region for drying indoor air circulation flow for realizing region that hot-gas channel connection is located at outside the drying room of region is followed
On the air inlet pipeline of ring blower；The back segment of the hot-gas channel provides the heat supply of circulating air with to the central heat exchanger
The bleeding point of circulating fan connects, and is connect with region drying room by the exhaust pipe with exhaust air-valve, is dried region with realizing
The region indoor gas of drying is not entered in dry chamber and high temperature flue is extracted into heat exchange in the central heat exchanger.
The exhaust gas of the waste gas combustion furnace introduces installation on pipe and takes out exhaust gas fan, and the exhaust gas introduces pipe and is connected to region
In drying room, to enter burning disposal in the waste gas combustion furnace from pumping exhaust gas in each drying room.
The fresh air outlet of the fresh air heat exchanger is discharged into pipe by fresh air with region drying room and connect.
The fresh air heat exchanger connects fresh-air fan.
The utility model becomes distribution heat exchange to concentrate heat exchange, while original indirect heat exchange case becomes directly mixed
Wind heating, reduces the production and installation difficulty of equipment；Due to not needing each regional deployment heat exchanger, so that total system
Volume and surface area reduce, and reduce the loss of heat.Relative to the method for indirect heat exchange, directly mixed wind heating is improved to mentioning
The response speed of high system entirety, while being advantageously implemented being precisely controlled for each area's temperature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the Two-way Cycle drying system of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of Two-way Cycle drying system, comprising:
Waste gas combustion furnace 1, for region drying room provide high-temperature gas central heat exchanger 2 and for region dry
Dry chamber provides the fresh air heat exchanger 3 of fresh air after heating, and the high-temperature flue gas discharge pipe 10 of the waste gas combustion furnace is successively passed through described
Central heat exchanger and fresh air heat exchanger in, to provide heat exchange thermal energy to the central heat exchanger and fresh air heat exchanger,
It is directly discharged into atmosphere after heat exchange；
The central heat exchanger by hot-gas channel 10 with and connect the hot-gas channel with mixing valve 12
The connection of each hot-gas channel be located at outside multiple regions drying room 6 and dry indoor air circulation for realizing region
On the air inlet pipeline of the region circulating fan 13 of flowing；The back segment of the hot-gas channel is provided with to the central heat exchanger
The bleeding point of the heating cycle blower 5 of circulating air connects, and passes through band with each region drying room 6 separated and be vented air-valve 7
Exhaust pipe connection, be extracted into institute to realize not entering region in region drying room and high temperature flue and dry indoor flue gas
State heat exchange in central heat exchanger 1；
The fresh air for reaching technological temperature after the heat exchange of the fresh air heat exchanger is new by connecting with region drying room
Wind is discharged into pipe 8 and is discharged into the drying room of region, to reduce voc concentration in drying room.
The exhaust gas of the waste gas combustion furnace introduces installation on pipe 9 and takes out exhaust gas fan 4, and the exhaust gas introduces pipe and is connected to area
In the drying room of domain, the waste gas combustion furnace burning disposal is entered to take out exhaust gas out of each drying room.
It should be noted that the exhaust gas that exhaust gas fan 4 connects of taking out introduces on the side wall of pipe 9 in the utility model
Branch pipe (not shown) can be introduced by the multiple exhaust gas for leading to each region drying room of a piping connection, by multiple regions
It dries after indoor exhaust gas summarizes and is introduced into waste gas combustion furnace burning disposal, as the company of exhaust pipe and high-temperature gas pipeline back segment
It is the same to connect mode；The same fresh air is discharged on the side wall of pipe 8 can connect multiple respectively lead to respectively by a connecting tube
A region dries indoor fresh air and is discharged into branch pipe (not shown), and fresh air is sent in the drying room of each region.
The utility model has the following characteristics that

It is sent into hot-gas channel after heat exchange heating.
3) after high-temperature gas is sent into each region by mixer selector valve by high-temperature flue gas pipe, then it is each by region circulating fan feeding
In a region drying room, the aperture by controlling mixer selector valve can control each area's technological temperature, complete the directly mixed wind in drying room
Heating cycle.
4) each area's exhaust air-valve is associated with mixed wind air-valve, and heating cycle blower extracts drying indoor gas by exhaust air-valve
It is not entered with high-temperature flue gas pipe and enters central heat exchanger together with the high-temperature gas of drying room, between completing system outside the drying room
Connect heat exchange cycle.
5) fresh air heat exchanger is set, and fresh-air fan extracts fresh wind and enters fresh air heat exchanger, exchanges heat, reach with flue gas
It is sent into inside drying room body after technological temperature, reduces voc concentration in drying room.
6) simultaneously waste gas combustion furnace by take out exhaust gas fan exhaust gas is taken out out of drying room, by combustion of natural gas to exhaust gas into
Row burning disposal, the high-temperature flue gas that emission request is met after processing subsequently enter central heat exchanger and fresh air heat exchanger, heat exchange drop
Warm heel row is to atmosphere.
The utility model has beneficial effect below
1) distribution heat exchange is become concentrating heat exchange, while original indirect heat exchange case becomes directly mixing wind heating,
Reduce the production and installation difficulty of equipment；
2) it due to not needing each regional deployment heat exchanger, so that the volume of total system and surface area reduce, reduces
The loss of heat.
