1. An apparatus for on-line temperature measurement and gas sampling used in chute area of dry CDQ coke oven comprising:
an oven external unit including a temperature indicator, a gas tube, and a vacuum tank, a precision of said temperature indicator is 0.1 degree C. and said vacuum tank possesses a gas inlet valve, a gas outlet valve and a vacuum gage;
an oven internal unit including a temperature measuring element, said temperature measuring element is a non-contact infrared temperature probe with ceramic protective sleeve, a measuring temperature range of said probe ranges is from 500 degree C. to 1500 degree C., a detection distance range is from 0.8 meters to 3 meters, the minimum size of detection target is 4 millimeters;
wherein, the temperature measuring element is placed in an upper channel of a high-temperature ceramic tube with double-channel, a lower channel of the high-temperature ceramic tube with double-channel is a channel of sampling gas in a CDQ coke oven;
wherein, the high-temperature ceramic tube with double-channel is located at top of the chute area of the CDQ coke oven and passes through an oven shell and an oven wall outside the oven shell along a radical direction of the CDQ coke oven;
wherein, the temperature measuring element connects with the temperature indicator via a temperature signal transmission wire protected by a second ceramic sleeve;
wherein, an end of the lower channel of the high-temperature ceramic tube with double-channel located outside the CDQ coke oven connects with the gas tube of the vacuum tank and is controlled by the gas inlet valve, a part of the high-temperature ceramic tube with double-channel outside the CDQ coke oven is wrapped by a cooling device.
