Abstract

A cooling system for the decoating system includes a sensor, a control device, and a controller communicatively coupled with the sensor and the control device. The sensor is configured to measure a characteristic of the cooling system in the decoating system, the control device controls the characteristic of the cooling system, and the controller is configured to adjust the control device to adjust the characteristic of the cooling system based on at least one of a measured temperature within the decoating system or the measured characteristic. A method of controlling a temperature of the decoating system includes measuring a temperature within a piece of equipment of the decoating system and measuring a characteristic the cooling system in the piece of equipment of the decoating system. The method includes controlling the cooling system to adjust the characteristic based on at least one of the measured temperature or the measured characteristic.

First claim

That which is claimed is:

1. A method of controlling a temperature of a decoating system with a cooling system, the method comprising:
measuring a temperature within a piece of equipment of the decoating system;
measuring a coolant characteristic of a coolant dispensed by a sprayer of the cooling system into the piece of equipment of the decoating system and receiving the measured coolant characteristic, wherein the coolant characteristic is a fluid pressure of the coolant; and
using a coolant control device to adjust the coolant characteristic such that the cooling system provides at least one of a desired temperature or a desired coolant characteristic with the coolant,
wherein the coolant control device is a pressure control device, and wherein adjusting the coolant control device comprises selectively controlling the fluid pressure of the coolant with the pressure control device based on the measured temperature and the measured fluid pressure.

2. The method of claim 1 , wherein the coolant characteristic is a first coolant characteristic, wherein the method further comprises measuring a second coolant characteristic comprising at least one of a a fluid flow rate of the coolant, or a spray angle of the coolant.

3. The method of claim 1 , wherein the piece of equipment comprises at least one of a kiln, an afterburner, and a duct between the afterburner and kiln of the decoating system.

4. The method of claim 1 , wherein the coolant characteristic is a first coolant characteristic and the coolant control device is a first coolant control device, wherein the method further comprises measuring a second coolant characteristic comprising a spray angle of the coolant and adjusting the second coolant characteristic with a second coolant control device, wherein the second coolant control device is a nozzle of the sprayer, and wherein adjusting the second coolant control device comprises selectively positioning the nozzle to adjust the spray angle based on the measured temperature and the measured spray angle.

5. The method of claim 1 , wherein the coolant characteristic is a first coolant characteristic and the coolant control device is a first coolant control device, wherein the method further comprises measuring a second coolant characteristic comprising a fluid flow rate of the coolant and adjusting the second coolant characteristic with a second coolant control device, wherein the second coolant control device is a control valve that selectively enables fluid flow of the coolant to the sprayer, and wherein adjusting the second coolant control device comprises selectively positioning the control valve at a position from a fully closed position to a fully open position to control the fluid flow rate based on the measured temperature and the measured fluid flow rate.

6. The method of claim 5 , wherein adjusting the second coolant control device comprises positioning the control valve such that the fluid flow rate is from a minimum fluid flow rate to a maximum fluid flow rate based on the measured temperature and the measured fluid flow rate, and wherein the minimum fluid flow rate is greater than 0.0 L/min.

7. A method of controlling a temperature of a decoating system with a cooling system, the method comprising:
measuring a temperature within a piece of equipment of the decoating system;
measuring a characteristic the cooling system in the piece of equipment of the decoating system and receiving the measured characteristic, wherein the characteristic is a fluid pressure of a coolant; and
controlling the cooling system to adjust the characteristic such that the cooling system provides at least one of a desired temperature or a desired characteristic,
wherein the cooling system comprises a pressure control device, and wherein controlling the cooling system comprises selectively controlling the fluid pressure of the coolant with the pressure control device based on the measured temperature and the measured fluid pressure.

8. The method of claim 7 , wherein the characteristic is a first characteristic, and wherein the method further comprises controlling the cooling system to control a gas characteristic in the piece of equipment, and wherein the piece of equipment comprises a kiln of the decoating system.

9. The method of claim 8 , wherein the gas characteristic is an oxygen level within the kiln, and wherein controlling the cooling system comprises controlling an oxygen control system of the cooling system based on at least one of the measured temperature or the measured oxygen level such that the cooling system provides at least one of the desired temperature or a desired oxygen level.

10. The method of claim 8 , wherein the gas characteristic is an organic concentration within the kiln, and wherein controlling the cooling system comprises controlling an organics control system of the cooling system based on at least one of the measured temperature of the measured organic concentration such that the cooling system provides at least one of the desired temperature or a desired organic concentration.
