Abstract
The utility model discloses a gamma -ray detection device for boiler system belongs to the regulation of burning or controls technical field, characterized in that: it includes consecutive gamma X -ray detector, photomultiplier and the preamplifier who connects, gamma X -ray detector converts the gamma -ray of receiving to light signal, and photomultiplier becomes the signal of telecommunication with gamma X -ray detector's light signal conversion, and preamplifier enlargies photomultiplier's the signal of telecommunication. This detection device can detect the gamma -ray volume in the coal ash storehouse through installing gamma X -ray detector on the coal ash storehouse to calculate the increment of gamma -ray in the coal ash storehouse, calculate pulverized coal combustion according to this increment and rate, judge whether the buggy fully burns, provide the basis for boiler system's energy -conservation and composite control.
Description
Technical field
The utility model belongs to transport or storage device technical field, is specifically related to a kind of steam generator system gamma-ray testing apparatus.
Background technology
Boiler, as a kind of energy conversion, is used for converting the chemical energy of electric energy or fuel steam, high-temperature water or the organic heat carrier with certain heat energy to, is widely used in thermal power station, boats and ships, locomotive and industrial and mining enterprises.Along with the fast development of industry, energy-conserving and environment-protective are more and more taken seriously, and boiler, as main energy sources equipment, is also put on the operation schedule of energy-saving and emission-reduction gradually.
The control of current domestic boiler mainly adopts instrument to control and DCS centralized control two kinds of patterns, and conventional instrument controls to also exist problems such as relying on manual operations, control by rule of thumb; DCS control system is monitored boiler for producing process with the form of man-machine interface, reduces operation easier, overcomes in view of conventional instrument forms boiler control system Problems existing.But, no matter control by instrument or all need by DCS centralized control basic detected parameters as control foundation.
Have in prior art and adopt the parameter such as fire box temperature, boiler main vapour pressure as parameter, although also for certain contribution has been made in the control of steam generator system, but the Partial controll of steam generator system can only be realized, the combustion case of coal dust in burner hearth can not be judged, cause the environmental protection and energy saving of steam generator system to control still to have much room for improvement.
Therefore, the more comprehensive control system of a steam generator system be researched and developed, first find suitable detected parameters, and development accurately can detect the device of this parameter.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of steam generator system gamma-ray testing apparatus, can detect gamma-rays amount in coal ash storehouse.
For solving the problems of the technologies described above, the technical solution of the utility model is: design a kind of steam generator system gamma-ray testing apparatus, it is characterized in that: comprise the gamma ray detector, photomultiplier and the prime amplifier that are connected successively;
Gamma ray detector converts the gamma-rays of reception to light signal, and photomultiplier converts the light signal of gamma ray detector to electric signal, and prime amplifier amplifies the electric signal of photomultiplier.
Preferably, also comprise analog-to-digital conversion module, analog-to-digital conversion module converts the analog electrical signal of prime amplifier to digital signal.
Preferably, described gamma ray detector is NaI (Tl) crystal.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model can by being arranged on coal ash storehouse by gamma ray detector, detect the gamma-rays amount in coal ash storehouse, thus calculate gamma-ray increment in coal ash storehouse, coal combustion rate is gone out according to this incremental computations, judge coal dust whether Thorough combustion, for the energy-conservation of steam generator system and Comprehensive Control provide foundation.
2, the utility model structure is simple, can be calculated the increment of coal ash, be convenient in industry apply by the accurate gamma-rays gauge detected in coal ash.
Accompanying drawing explanation
Fig. 1 is electrical diagram of the present utility model.
Mark in figure: 1, NaI (Tl) crystal; 2, photomultiplier; 3, prime amplifier; 4, analog-to-digital conversion module.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, NaI (Tl) crystal 1, photomultiplier 2, prime amplifier 3 and the analog-to-digital conversion module 4 that are connected successively is provided with in the utility model; The gamma-rays that NaI (Tl) crystal 1 receives, gamma-rays converts light signal to by NaI (Tl) crystal 1, photomultiplier 2 converts the light signal of NaI (Tl) crystal 1 to electric signal, prime amplifier 3 amplifies the electric signal of photomultiplier 2, analog-to-digital conversion module 4 converts the analog electrical signal of prime amplifier 3 to digital signal, become the input signal of single-chip microcomputer, for it provides control foundation.
During use, NaI (Tl) crystal 1 is arranged on coal ash storehouse, gamma-rays in coal ash is absorbed by NaI (Tl) crystal 1 and produces corresponding light signal, the discernible digital signal of single-chip microcomputer is become after the process of photomultiplier 2, prime amplifier 3 and analog-to-digital conversion module 4, thus by gamma-ray incremental computations coal combustion rate, and then judging whether Thorough combustion provides foundation for it, the Optimizing Combustion for steam generator system controls to lay the foundation.
Certainly, above-mentioned NaI (Tl) crystal 1 can also adopt and can detect other detector gamma-ray replacement.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
