Abstract
The utility model discloses a cylindrical silo protection device, and relates to cylindrical silo protection devices. The cylindrical silo protection device is composed of a cylindrical silo environment detecting system, a cylindrical silo explosion protection system, a cylindrical silo inflation exhaust system and a control system. The cylindrical silo environment detecting system is mainly used for monitoring the poisonous gas, the dust, the oxygen content, the material level and the temperature inside a cylindrical silo. The cylindrical silo explosion protection system is mainly used for releasing the pressure produced by gas explosion inside the cylindrical silo. The cylindrical silo inflation exhaust system is composed of a pressure reduction system, an inflation system and an exhaust system. The control system controls the cylindrical silo inflation exhaust system according to a signal fed back by the cylindrical silo environment detecting system. The cylindrical silo protection device has the advantages that the control system is of a gathering and distributing structure, openness is good, expansion is easy, the reliability of the system is improved, the system risks are dispersed, redundant configuration is adopted, reliability is high, operations of the whole system are carried out on an upper computer, the system has an interlock protection function, and the networking among a coal delivering programmed control system, a power plant auxiliary system and a supervisory information system can be achieved according to demands.
Description
Technical field
The utility model relates to a kind of silo fender guard, and specifically a kind of silo fender guard is particularly useful for the protection of coal storage silo.
Background technology
At present, it is more that the enterprises such as the Coal Chemical Industry of domestic various places, thermal powerplant use the situation of silo storage coal, but domestic silo coal storage repeatedly catches fire, even the situation that has silo to blast.Therefore, the importance of silo fender guard is just more and more outstanding.But do not have at present a kind of failure-free, comprehensive silo fender guard.Therefore how the environment in the silo also just can't be known, often because noxious gas content is too much, causes silo blast and personal casualty.
Summary of the invention
For preventing that the silo noxious gas from gathering, the generation such as equipment and gas explosion in the silo is burnt in the coal storage spontaneous combustion; prevent trouble before it happens; the utility model provides a kind of silo fender guard, and the parameter of the toxic gas detection in the silo (CO, CH4), dust detection, oxygen content detection, the inner material level detection of silo, temperature detection is monitored.When silo environmental monitoring system parameter exceeds allowed band, send immediately alerting signal, in time remind the operations staff to take necessary measure, in time open air inflator system, exhaust system by control system.Eliminate accident potential, ensure safe in operation.And can when silo generation gas explosion, in time carry out pressure release to the pressure that blast produces by the silo explosion protection system, each equipment in the protection silo.
The utility model is realized with following technical scheme: a kind of silo fender guard comprises silo environmental monitoring system, silo explosion protection system, silo fill-drain syctem and composition of the control system.The silo environmental monitoring system mainly is the monitoring to silo toxic gas detection (CO, CH4), dust detection, oxygen content detection, the inner material level detection of silo, temperature detection.The silo explosion protection system mainly is when silo generation gas explosion, can in time carry out pressure release to the pressure that blast produces, each equipment in the protection silo.The silo fill-drain syctem is comprised of depressurized system, air inflator system, exhaust system.Control system is by the signal that silo environment measuring feedback is come the silo fill-drain syctem to be controlled, and reaches protection to silo thereby play improvement to the silo work condition environment.
The beneficial effects of the utility model are: this device detects unfavorable operating mode in the silo automatically by the silo environmental monitoring system, under the control of control system, opens the silo fill-drain syctem, thereby reaches the purpose of improving the silo environment.Also can discharge the pressure that gas explosion produces by the silo explosion protection system simultaneously, avoid personnel are caused unnecessary injury, to the destruction of silo body and relevant device.
Description of drawings
Fig. 1 is the utility model electrical schematic diagram;
Fig. 2 is the utility model structural representation.
Among the figure: 1. oxygen content detects, 2. toxic gas detection, and 3. dust detects, 4. temperature detection, 5. the inner material level of silo detects, 6. silo explosion protection system, 7. exhaust system, 8. air inflator system, 9. depressurized system.
The specific embodiment
As shown in Figure 1, a kind of silo fender guard comprises silo environmental monitoring system, silo explosion protection system, silo fill-drain syctem and composition of the control system.
At first toxic gas detection (CO, CH4) sensor, dust detecting sensor, oxygen content detecting sensor, the inner material level detecting sensor of silo, temperature detection sensor are installed in the silo, and the silo environment detected in real time, then the result who detects is imported into control system, control system will show each testing result on the spot by data trap, when silo environmental monitoring system parameter exceeds allowed band, send immediately alerting signal, in time remind the operations staff to take necessary measure.When reporting to the police as exceeding standard when toxic gas detection (CO, CH4) sensor, temperature detection sensor parameter, the operations staff just must open air inflator system and exhaust system by control system, oxygen content in the dilution silo, stop the inner coal storage of silo spontaneous combustion, glow, simultaneously noxious gas is discharged the silo outside, until when toxic gas detection (CO, CH4) sensor, temperature detection sensor parameter normal operation, can stop air inflator system and exhaust system; When dust detecting sensor parameter is reported to the police, can discharge the silo outside to dust by opening exhaust system; When the oxygen content parameter was reported to the police, the operations staff must withdraw silo, in order to avoid the anoxic life threatening; When the inner material level detecting sensor of silo parameter was reported to the police, the operations staff must stop to continue coal in silo.When the toxic gas detection in the silo (CO, CH4), when the dust detected parameters exceeds standard too high blasting, the silo explosion protection system will be opened explosion protection the pressure that blast produces is excreted out to silo.Simultaneously, the operations staff can understand by control system the mode of operation of explosion protection.
Control system must can both be shared the running state of detected all data of silo environmental monitoring system, silo explosion protection system mode of operation, silo fill-drain syctem with defeated coal stored program controlled.That can realize position, a distant place carries out comprehensive, real-time monitoring to the silo operating mode.
