Abstract
The utility model relates to a cold sediment machine equipment of defeated sediment pipeline, the inside into water flow transmitter that is equipped with of inlet tube, the inside water flow transmitter that is equipped with out of outlet pipe, the flow transmitter of intaking all is connected with programmable controller with play water flow transmitter, the control of adopting the flow measurement method to go on leaking detects, the quality or the volume conservation that flow based on pipeline midstream object matter concern, be that injection rate and discharge poor of liquid should equal stagnant fluid volume in the pipeline, in the stable back of pipeline operation, the inflow volume regards as equally with the discharge, so when the input and output flow that detects cold sediment machine both ends, if the difference is greater than the certain limit, show promptly the institute taken place to leak in the survey pipeline, flow transmitter carries out data acquisition with play water flow transmitter through intaking, finally carry out analysis of the data through programmable controller, realize the leakage control of cold sediment machine, simple structure is easily capable, it is convenient to manufacture, low cost, therefore, the clothes hanger is strong in practicability.
Description
Technical field
The utility model relates to a kind of lag cooler leak detecting device.
Background technology
Lag cooler is the cooling of furnace slag treating apparatus that fluidized-bed combustion boiler uses, and reduces slag temperature by the heat exchange of low-temperature circulating water and slag, simultaneously by this part heat recovery and utilization, improves boiler thermal output.There is all kinds structure, monotubular, the bitubular, two-tube row, bitubular row, membrane wall, warehouse separated type etc., no matter how the version of various lag cooler changes, are all the noncontact heat exchanges of water and slag, cooling water is at cylindrical shell or pipeline internal circulation flow, and high temperature furnace slag flows at outer wall.
The cooling water that lag cooler uses is generally condensed water in boiler source, pressure reaches as high as 4MPa, burner hearth slag temperatures as high 950-1000 ° of C simultaneously, lag cooler is caused to become the rotating operation equipment of a HTHP, mutually cross in the inner various thermal stress of lag cooler, thus running the cracking leakage that body weld seam very likely occurs in use procedure, cause cooling water directly to mix with slag.When there being cooling water minor leakage to occur, high temperature furnace slag directly can evaporate the moisture of leakage, does not substantially affect the normal operation of equipment; Crack propagation is leaked and is rolled up thereupon, and slag rapid evaporation can not fall cooling water, and a large amount of cooling water mixes mutually with slag, is bonded in lag cooler body, causes scrapping of the difficult even cooling element of overhaul of the equipments.
Owing to never having effective lag cooler leakage monitoring means and facility, during lag cooler generation minor leakage accident, can not find timely, leak until there is large discharge, cause slag to bond, after making lag cooler run generation overload shutdown, just have operations staff's site inspection and find to leak; And now a large amount of slag is bonded in lag cooler body after mixing with cooling water in a large number, gets rid of to trouble shooting and cause extreme difficulties, need to process for a long time, even cause scrapping of cooling element, had a strong impact on the safe and stable operation of boiler.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of lag cooler leak detecting device, improves the economical of lag cooler leak detection and practicality.
The technical solution of the utility model is: a kind of lag cooler leak detecting device, comprise cooling line 1, cooling line 1 is connected with water inlet pipe 4 and outlet pipe 2, water inlet pipe 4 inside is provided with flow of inlet water transmitter 5, outlet pipe 2 inside is provided with water flow transmitter 3, and flow of inlet water transmitter 5 is all connected with Programmable Logic Controller 6 with water flow transmitter 3.
Optimally, be also provided with alarm 7, alarm 7 is connected with Programmable Logic Controller 6.
The utility model comprises cooling line 1, cooling line 1 is connected with water inlet pipe 4 and outlet pipe 2, water inlet pipe 4 inside is provided with flow of inlet water transmitter 5, outlet pipe 2 inside is provided with water flow transmitter 3, flow of inlet water transmitter 5 is all connected with Programmable Logic Controller 6 with water flow transmitter 3, flow detection method is adopted to carry out the monitor and detection leaked, based on quality or the volume conservation relation of flowing material flowing in pipeline, namely the injection rate of liquid and the difference of discharge should equal the interior Fluid Volume stagnated of pipeline, after conduit running is stable, influx and discharge are considered as equal, so when detecting the input and output flow at lag cooler two ends, if difference is greater than certain limit, namely show to leak in institute's test tube road, data acquisition is carried out by flow of inlet water transmitter and water flow transmitter, the analysis of data is carried out eventually through Programmable Logic Controller, realize the leak supervision of lag cooler, simple for structure, it is convenient to manufacture, cost is low, practical.
The utility model is also provided with alarm 7, alarm 7 is connected with Programmable Logic Controller 6, when occurring to leak, undertaken reminding by alarm and access lag cooler DCS system, slag in automatic-discharging lag cooler also closes water source, reduces the harm of leaking and causing, thus improves the service life of equipment, structure is simple, practical.

Detailed description of the invention
Illustrate the utility model below in conjunction with drawings and embodiments, be all described for lag cooler leak detecting device in drawings and Examples.
A kind of lag cooler leak detecting device of the present utility model, comprise cooling line 1, cooling line 1 is connected with water inlet pipe 4 and outlet pipe 2, water inlet pipe 4 inside is provided with flow of inlet water transmitter 5, outlet pipe 2 inside is provided with water flow transmitter 3, flow of inlet water transmitter 5 is all connected with Programmable Logic Controller 6 with water flow transmitter 3, is also provided with alarm 7, and alarm 7 is connected with Programmable Logic Controller 6.
The course of work, flow detection method is adopted to carry out the monitor and detection leaked, based on quality or the volume conservation relation of flowing material flowing in pipeline, namely the injection rate of liquid and the difference of discharge should equal the interior Fluid Volume stagnated of pipeline, after conduit running is stable, influx and discharge are considered as equal, so when detecting the input and output flow at lag cooler two ends, if difference is greater than certain limit, namely show to leak in institute's test tube road, data acquisition is carried out by flow of inlet water transmitter 5 and water flow transmitter 3, the analysis of data is carried out eventually through Programmable Logic Controller 6, realize the leak supervision of lag cooler.
