Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment
The processing system of industry coating production line organic exhaust gas as shown in Figure 1, including dust filter unit 8, exhaust gas fan 1,
First plate heat exchanger 2, the second plate heat exchanger 3, pipe heat exchanger 4, catalyst chamber 5, cracking room 6 and heat supply blower 7；
The outlet of the dust filter unit 8 is connected by pipeline with the import of the exhaust gas fan 1, the exhaust gas fan
1 outlet is connected by pipeline with the low temperature import of first plate heat exchanger 2, first plate heat exchanger 2 it is low
Temperature outlet is connected by pipeline with the low temperature import of second plate heat exchanger 3, the low temperature of second plate heat exchanger 3
Outlet is connected by pipeline with the low temperature import of the pipe heat exchanger 4, and the low-temperature outlet of the pipe heat exchanger 4 passes through
Pipeline is connected with the import of the catalyst chamber 5, and the outlet of the catalyst chamber 5 passes through the import phase of pipeline and the cracking room 6
Connection；
The outlet of the cracking room 6 is connected by pipeline with the high temperature import of the pipe heat exchanger 4, and the tubular type is changed
The hot outlet of hot device 4 is connected by pipeline with the high temperature import of second plate heat exchanger 3, second plate-type heat-exchange
The hot outlet of device 3 is connected by pipeline with the high temperature import of first plate heat exchanger 2, first plate-type heat-exchange
The hot outlet of device 2 is connected by pipeline with the air inlet of the heat supply blower 7.
The control valve of controllable gas flow is all equipped on the pipeline.
The utility model treatment process be its organic exhaust gas first pass through dust filter unit 8 filter it is out of dust, it is filtered useless
Gas is sent to the first plate heat exchanger 2, the second plate heat exchanger 3, pipe heat exchanger 4 by exhaust gas fan 1, reaches at catalysis
Managing temperature in catalyst chamber 5 through excessive wind deflector keeps its cloth wind uniform, allows being improved of catalytic effect, then after catalysis
Temperature is improved under the condition of high temperature again and reduces the consumption of the energy to reduce temperature rise in the progress Pintsch process of cracking room 6, reaches section
It can effect.
(windage is big, heat exchange efficiency using board-like for first plate heat exchanger 2, the second plate heat exchanger 3, pipe heat exchanger 4
It is high) it is combined with tubular type (windage is small, and heat exchange efficiency is low), make it have complementary advantages to reach effective heat utilization；Its heat exchanger
It is divided into both sides ventilation, on one side into low temperature waste gas, on one side into treated high-temperature cleaning hot wind, to reach with high-temperature heating low temperature
Heat transfer effect.
Catalyst chamber 5 is combined with cracking room 6 achievees the effect that processing exhaust gas can reduce energy consumption again, and filling is expensive in catalyst chamber 5
Organic exhaust gas can be decomposed in lower temperature, nitrogen dioxide and water are converted it into for metallic catalyst, to generate clear
The gas of clean high temperature.
Starting exhaust gas fan 1 carries out gas sampling first, and exhaust gas passes through the first plate heat exchanger 2, the second plate heat exchanger
3, pipe heat exchanger 4 reaches catalyst chamber 5 and carries out catalytic treatment, and then arriving cracking room 6, (cracking room is equipped with pressure transmitter prison
Survey cracking chamber pressure) secondary treatment is carried out, after the first plate heat exchanger 2, the second plate heat exchanger 3, pipe heat exchanger 4
Production line is sent to using heat supply blower 7 to be used.When operation, heat supply blower is that fixed frequency is run, and exhaust gas fan is according to cracking room 6
Pressure makees the adjusting of PID analog quantity.
It is specific: organic exhaust gas collection being come first with exhaust gas fan 1, is then delivered to 2 low temperature of the first plate heat exchanger
Import is tentatively heated, and is heated again to 3 low temperature import mouth of the second plate heat exchanger from 2 low-temperature outlet of the first plate heat exchanger, from the
Then organic exhaust gas that 3 low-temperature outlet of double-plate heat exchanger arrives pipe heat exchanger (4) low temperature import reheating again and carrys out collection reaches
Required temperature, is then entered catalyst chamber 5 from 4 low-temperature outlet of pipe heat exchanger again and is urged using noble metal before decomposing to catalyst chamber 5
Agent decomposes organic exhaust gas (to resolve into carbon dioxide and hydrone), obtains a part of high-temperature gas, then arrives cracking room again
680 DEG C or more are heated on the basis of 6 high temperature after disassembly, organic exhaust gas is allowed sufficiently to crack, discharges more heats, then again
Into 4 high temperature import of pipe heat exchanger, then from 4 hot outlet of pipe heat exchanger to the 3 high temperature import of the second plate heat exchanger, then from
Second plate heat exchanger, 3 hot outlet is heated to the 2 high temperature import of the first plate heat exchanger to exhaust gas, then from the first plate-type heat-exchange
Using heat supply blower 7, treated, high-temperature cleaning air is sent in the baking box of production line 2 hot outlet of device.
