Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1: the utility model discloses the schematic structure.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the attached drawings, but the invention can be implemented in many different ways as defined and covered by the claims:
as shown in figure 1, the utility model provides a catalytic combustion exhaust treatment system with safety interlocking function, including PLC controller and the gas collecting channel 1 that connects gradually, waste gas collecting pipe 2, bypass pipeline 3, catalytic combustion furnace 4, catalytic combustion furnace is connected with tuber pipe 12 on 4, is connected with fan 13 on the tuber pipe 12, and gas collecting channel 1 generally can be installed in the workshop of mill, collects the waste gas that comes from in the workshop.
The waste gas enters the catalytic combustion furnace 4 through the gas collecting hood 1, the waste gas collecting pipeline 2 and the bypass pipeline 3, and the waste gas is combusted in the catalytic combustion furnace 4 and then is extracted through the air pipe 12.
The junction of the waste gas collecting pipeline 2 and the bypass pipeline 3 is far away from the external port of the bypass pipeline 3, the waste gas collecting pipeline 2 is provided with a concentration detector 6 and a temperature sensor 7, and the concentration detector 6 is arranged close to the gas collecting channel 1. The temperature sensor 7 and the concentration detector 6 are positioned in a workshop, the temperature sensor 7 is far away from the gas-collecting hood 1, the concentration detector 6 and the temperature sensor 7 transmit signals to the PLC, and the bypass valve 10 is controlled by the PLC.
When the concentration detector 6 detects that the concentration of the exhaust gas entering the exhaust gas collecting pipeline 2 is higher than 25% of the explosion limit value of the exhaust gas, or the temperature sensor 7 at the front end detects that the temperature in the exhaust gas collecting pipeline 2 is higher than a set value, the PLC controller controls to open the bypass valve 10 on the bypass pipeline 3, fresh air is introduced to reduce the concentration or the temperature of the exhaust gas so as to ensure safe operation, and the bypass valve 10 is arranged close to an external port of the bypass pipeline 3.
The elbow of the waste gas collecting pipeline 2 close to the bypass pipeline 3 is provided with a node explosion venting valve I5, the external port of the bypass pipeline 3 is provided with a node explosion venting valve II 9, and the catalytic combustion furnace 4 is provided with an explosion venting valve 11, so that the catalytic combustion furnace 4 and the elbow of the waste gas collecting pipeline 2 can be timely decompressed, and the explosion pressure can be prevented from impacting and damaging equipment.
Be equipped with spark arrester 14, collection liquid discharge port 8 on the waste gas collection pipeline 2, collect liquid discharge port 8 and be located temperature sensor 7 and node and let out and explode between the valve 5, collect liquid discharge port 8 and be located the workshop outside, spark arrester 14 is located and collects liquid discharge port 8 and node and lets out and explode between the valve 5 and be close to collection liquid discharge port 8 and set up. Because the difference in temperature has between the pipeline wall of the waste gas collecting pipeline 2 in the pipeline wall of the waste gas collecting pipeline 2 outside the workshop and the workshop, if the waste gas is condensed into liquid form after leading to the waste gas collecting pipeline 2 outside the workshop, then can discharge through the liquid collecting discharge port 8, prevent to cause the waste gas concentration local too high because of the hydrops, and then arouse the possibility of detonation. And the flame arrester 14 prevents open flame generated in the catalytic combustion furnace 4 from entering the plant from the exhaust gas collection pipe 2.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, if the method and the technical solution of the present invention are adopted, the present invention can be directly applied to other occasions without substantial improvement, and the present invention is within the protection scope of the present invention.
