Description

Integrated coke cake temperature measuring instrument and use method thereof

Technical Field

The invention relates to the technical field of thermometers, in particular to an integrated coke cake thermometer and a using method thereof.

Background

The central temperature of the coke cake is an important index for reflecting the uniform maturity degree of the coke, is a comprehensive result of transverse heating and high-direction heating of the coke oven, and the uniformity of the central temperature is an important basis for checking the perfection degree of the structure and the heating system of the coke oven. The temperature curve and the horizontal row vertical flue hole on the surface of the coke cake are corresponding, and through the temperature data on the surface of the coke cake, which pair of holes is low in temperature or high in temperature can be calculated, so that the vertical flue can be directly guided to adjust the fire, and the temperature of a transverse wall can also be simulated through the temperature on the surface of the coke cake.

Therefore, the measurement of the surface temperature of the coke cake is very important, and the current method for measuring the surface temperature of the coke cake comprises the following steps:

1. in the coke discharging process, measuring the temperature of the coke cake by using a handheld infrared thermometer;

2. at the initial stage of coal charging, a steel pipe is driven into a coal charging hole, and a thermocouple is inserted into the steel pipe for measurement.

The position scheme of the temperature measuring point is as follows:

2.1, carrying out measurement on a coal charging port through a longitudinal insertion pipe;

2.2, transversely inserting the tube from the side of the oven door.

The measured temperature points are the central temperatures of coke cakes at the positions right below the coal charging ports at the machine side and the coke side.

The method comprises the steps of forming holes with phi 50mm (smaller according to actual conditions) at the upper, middle and lower 3 positions of a machine side furnace door and a coke side furnace door, selecting 3 seamless steel pipes with phi 30mm or so (smaller than the diameter of the furnace door opening), 3000mm in length (the pipe length is determined according to the central position of a machine side coal loading port and a coke side coal loading port), opening one end and closing one end tip, and installing the furnace door with the opening after coke pushing of a coking chamber to be measured is finished. And inserting the seamless steel tube after the coal charging operation is finished, and inserting a thermocouple into the seamless steel tube after the coke cake is mature so as to measure the central temperature of the coke cake.

3. The coke cake center temperature was replaced by measuring the coke cake side surface temperature near the furnace wall.

The methods 1 and 2 have the defects of high labor intensity, severe operating environment, poor representativeness, difficulty in on-line direct measurement and the like. The method 3 can realize the on-line automatic measurement of the central temperature of the coke cake, and the temperature of the side surface of the coke cake close to the furnace wall is 20-40 higher than that of the central surface, so that the central temperature of the coke cake can be calculated in time.

The core part of the existing coke cake temperature measuring system is a split infrared optical fiber thermometer which consists of an optical system, a high-temperature-resistant quartz optical fiber and a signal processing system 3, wherein the optical system collects infrared light radiation (representing temperature) on the surface of a coke cake, transmits the infrared light radiation to an instrument through the optical fiber, and converts the light radiation intensity into a temperature signal in the instrument system.

The existing split infrared optical fiber thermometer has the following defects:

1. the split structure of the optical lens, the optical fiber and the signal processing is complex in structure and inconvenient to install and maintain;

2. the optical fiber is adopted to transmit optical signals to the signal processing device, so that the optical fiber is fragile and easy to break and is easy to break during installation;

3. the temperature measuring instrument is arranged on a coke guide grid of the coke guide car, the coke guide grid needs to extend out and retract during coke guide, and the optical fiber is bent continuously along with the coke guide grid and is easy to break;

4. the optical fibers with different bending radii have different conduction coefficients and cannot be calibrated and compensated, so that the measurement accuracy is influenced;

5. the optical fiber belongs to a customized product, the customization is required, the period is long, the cost is high, and the production cannot be quickly recovered once the optical fiber is damaged;

6. the split type structure is along with the split type temperature measurement scheme of vertical flame path, but the optical part mounted position is not long-term high temperature, utilizes the components of a whole that can function independently structure to place signal processing device far away, and is not significant.

The invention discloses an integrated coke cake temperature measuring instrument, which is different from the existing split coke cake temperature measuring instrument in the market.

The invention connects the sight tube, the photoelectric thermometer and the photoelectric thermometer bin into a whole, the photoelectric thermometer is arranged in the photoelectric thermometer bin to form a double-layer structure, after entering the photoelectric thermometer bin, the blowing air firstly enters the bin to be contacted with the photoelectric thermometer, because the temperature of the site environment is high or low, the blowing air with normal temperature can ensure that the photoelectric thermometer is always in a normal working temperature range, the blowing air rotates along the excircle tangential direction of the photoelectric thermometer from one side of the inner wall of the cast aluminum box and then enters the connecting tube, so that the blowing air stays in the bin for a longer time to fully realize heat exchange, the photoelectric thermometer and the positioning shaft are in small clearance fit, thus most of the blowing air enters the annular gap between the outer tube and the inner tube along radial holes, and finally the blowing air blows out from the sight tube to blow out coke particles falling into the sight tube.

The outer wall of the positioning shaft is provided with the sealing groove which can be filled with the O-shaped ring, and after the photoelectric thermodetector is inserted on the positioning shaft, the inside of the photoelectric thermodetector is connected with the inner hole of the inner pipe, so that when sweeping wind enters a circular seam between the outer pipe and the inner pipe along the radial hole, air blown out from the circular seam forms a micro vacuum in the inner area of the inner pipe, dust and the like in the inner pipe can be brought out, and meanwhile, moisture impurities and the like contained in the sweeping wind are prevented from being bonded on a lens of the photoelectric thermodetector.

A downward opening is reserved between the protective tube and the peeping coke plate, blowing gas finally flows into the atmosphere from the downward opening, rainwater is prevented from entering the peeping tube when rain falls through the structure of the peeping tube, a light path is isolated from an external high-dust environment to the maximum extent, and the normal work of the photoelectric thermometer can be guaranteed even if the blowing gas is short and temporarily cut off.

The endoscope tube and the photoelectric thermometer bin can be disassembled at the flange, and after long-time use, the photoelectric thermometer bin can be disassembled and cleaned, and the preferred embodiment of the invention is explained in detail by combining the drawings.

Many other changes and modifications can be made without departing from the spirit and scope of the invention. It is to be understood that the invention is not to be limited to the specific embodiments, but only by the scope of the appended claims.
