Embodiment:
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, the utility model is further detailed:
In the present embodiment, the utility model comprises body of heater 1, and body of heater is connected with burner 4; The tweer of body of heater 1 is useful on the water 2 of cooling; The utility model also includes boiler tube high temperature pick-up unit and body of heater apparatus for testing weeping, and described boiler tube high temperature pick-up unit and body of heater apparatus for testing weeping for the applicant at number of patent application are: 2010201304020 " boiler tube high temperature pick-up unit " and number of patent application are " apparatus for testing weeping " disclosed technical scheme of 2010201194302.
In the present embodiment, the temperature element of boiler tube high temperature pick-up unit is installed in the furnace sandwich by installation head, and A as shown in fig. 1, B, C position go out.Described temperature element is an armoured thermocouple 15, and the extension line of armoured thermocouple is by cutting ferrule 151 sealings; Lowest part at the fire tube steel plate 3 of body of heater is connected with the probe cassette T of body of heater apparatus for testing weeping by a run-down pipe 5, spout hole 51 is set on described probe cassette, when the liquid level in the probe cassette T rose to spout hole 51, automatic overflow can not accumulate the liquid in the fire tube to the outside.The leakage transmitter LT of the temperature transmitter of boiler tube high temperature pick-up unit and body of heater apparatus for testing weeping is connected on the Programmable Logic Controller QC-1.
The inner sleeve 152 of the installation head of the temperature element of described boiler tube high temperature pick-up unit, outer tube 153 are directly fixedlyed connected with fire tube steel plate 3.Described temperature element, promptly the extension line 201 of armoured thermocouple 15 passes body of heater flange 204 and fixing by high pressure graphite-filled packing seal 203 and pressure cap 202.The probe cassette T of described body of heater apparatus for testing weeping is that last liquid feeding side emptying, totally enclosed type detect box.Be provided with insulating material between described probe electrode 7 and the probe cassette T.
Principle of work of the present utility model is as follows:
Described boiler tube high temperature pick-up unit is to have on the fire tube steel plate in space of water at boiler tube, utilize installation head that water and detected steel plate are separated, the outer tube of temperature element installation head of the present utility model and inner sleeve constitute an interlayer air 154 between the two, play heat-blocking action, make the water 2 in the stove can not directly cool off the effect that temperature element is an armoured thermocouple, inner sleeve 152 is passed to armoured thermocouple to the heat of body of heater steel plate 3, cutting ferrule 151 is sealing temperature thermocouples 6, water and temperature element are separated, and pressure cap 151 is regulated the sealing elasticity.The extended line 201 body of heater flanges of armoured thermocouple 15 extend to outside the stove, and this flange adopts packing_seal, has both guaranteed the thermopair extension, plays sealing function again, and the water in the stove is not leaked outside.LT is the leakage transmitter among the figure, and the signal that leakage inspection probe cassette T is detected becomes switching signal, gives programmable controller input, output I/O assembly.
The leakage detection probe is made up of two electrodes 7, link to each other with leakage transmitter LT by high value insulating material sealing back, in case boiler tube burns out, leakage, liquid 2 flows out in the probe cassette T automatically in the bottom of fire tube steel plate 3, when liquid was dipped into electrode 7, detected signal was input to leakage transmitter LT and converts switching signal to, gave programmable controller QC and carried out data processing.When liquid in the stove flows into the stove tube inner bottom part of heating furnace, go in the detection probe box T by run-down pipe 5 automatic overflows, when the liquid level in the detection probe box T rose to spout hole, automatic overflow can not accumulate the liquid in the fire tube to the outside.After the signal that temperature and leakage detect is delivered to programmable controller I/O assembly, carry out demonstration and control by programmable controller QC.When measured any some temperature during near 475C °, the acousto-optic pre-alarm when reaching 475C °, is reported to the police, and when surpassing 485C °, cuts off gas flow by variable valve TV, blowing out automatically, and when leakage detection system has detected leakage, blowing out automatically.
Apparatus for testing weeping of the present utility model, adopt principle of overflow, in case boiler tube has burnt out leakage when occurring, the inevitable inflow automatically in the leakage detection probe box, when detecting liquid level, probe reports to the police automatically with blowing out automatically, when boiler tube any point temperature surpasses set temperature value, also by the automatic blowing out of programmable controller by programmable controller.
Install the armoured thermocouple 15 of temperature-detecting device, earlier internal and external casing 2,5 are soldered on the fire tube steel plate 1, guarantee that full weld does not leak, again armoured thermocouple 15 is inserted into the end, tighten pressure cap 151, the extended line of armoured thermocouple is passed by body of heater flange 204, as shown in Figure 2, tighten pressure cap 202, packing seal 203 good seals, the extended line that passes the armoured thermocouple 15 that passes 204 from the body of heater flange is connected with the temperature transmitter TE of high temperature pick-up unit again, described in the present embodiment point for measuring temperature has six, therefore, six temperature transmitter TE101 are set, TE102, TE103, TE104, TE105, TE106, the temperature input of programmable controller QC is linked in the output of temperature transmitter TE respectively, output module I/O-1, the I/O-2 respective terminal.The structure and the mounting means of body of heater of the present utility model and burner and body of heater flange are prior art.
The installation head of apparatus for testing weeping with temperature element is installed on the fire tube steel plate 3, and the run-down pipe 5 in that fire tube steel plate bottommost welding leakage detects welds probe cassette T again, and the high insulation tube 6 of described probe electrode fixes with leakage transmitter LT.On the connection terminal of the input module QC-1 that directly receives programmable controller QC of the leakage transmitter LT of described apparatus for testing weeping.The output of QC-1 is received on the variable valve TV, shown in Fig. 4.HMI is a display among Fig. 4.
