Abstract
The utility model discloses an explosion-proof temperature control system for a gas storage tank in the field of pressure containers. The explosion-proof temperature control system comprises a temperature detection unit mounted on a storage tank, wherein a signal output end of the temperature detection unit is connected with a signal input end of an A/D (analog/digital) conversion unit, the signal output end of the A/D conversion unit is connected with the signal input end of a micro-controller, the signal output end of the micro-controller is connected with the signal input end of a water pump control unit, and the water pump control unit is used for controlling a feed water pump to work. The explosion-proof temperature control system disclosed by the utility model improves the degree of automation, reduces the labor intensity of operation staff, improves the safety of the storage tank, avoids possible over-temperature damages and even explosion accidents of the storage tank caused by various reasons, and can be used for liquefied petroleum gas storage tanks.
Description
Technical field
The utility model relates to a kind of pressurized container, particularly a kind of gas holder.
Background technique
Will be provided with trickle or other cooling and insulating facilities in summer according to national security regulation inflammable gas gas holder, the storage tank wall temperature requires to be no more than 50 ℃, and in practice, the inflammable gas gas holder is general adopts artificial spraying cooling system.This artificial spraying cooling system needs operator's artificial observation gas holder temperature, requires operator that stronger sense of responsibility is arranged, and might surpass in the period of 50 ℃ at sweltering heat in summer storage tank wall temperature in period, often make an inspection tour tank area, and labor intensity is larger.
The model utility content
The purpose of this utility model is to provide a kind of gas holder explosion-proof temperature control system, has alleviated operator's labor intensity, improves the Security of storage tank, and the storage tank overtemperature of stopping may cause because of a variety of causes damages even explosive accident.
The purpose of this utility model is achieved in that a kind of gas holder explosion-proof temperature control system, comprise the temperature detecting unit that is arranged on storage tank, the signal output part of described temperature detecting unit is connected with the signal input part of A/D converting unit, the signal output part of described A/D converting unit is connected with the signal input part of microcontroller, the signal output part of described microcontroller is connected with the signal input part of water pump control unit, and described water pump control unit is controlled feed water pump work.
During the utility model work, by temperature detecting unit, the storage tank wall temperature is detected, testing signal is delivered to microcontroller through the A/D converting unit, when the storage tank wall temperature reaches 50 ℃, microcontroller sends control signal feed water pump control unit, and the spray thereby the startup feed water pump draws water is after the storage tank wall temperature is down to below 50 ℃ gradually, the microprocessor control feed water pump quits work, according to this circulation.Compared with prior art, the beneficial effects of the utility model are: the utility model has improved automaticity, alleviated operator's labor intensity, improved the Security of storage tank, the storage tank overtemperature of stopping may cause because of a variety of causes damages even explosive accident.The utility model can be used for liquefied petroleum gas storage tank.
In order to prevent the water pump frequent starting, be provided with time delay relay between described microcontroller and water pump control unit.
Description of drawings
Fig. 1 is the utility model control principle block diagram.
Embodiment
A kind of gas holder explosion-proof temperature control system as shown in Figure 1, comprise the temperature detecting unit that is arranged on storage tank, the signal output part of temperature detecting unit is connected with the signal input part of A/D converting unit, the signal output part of A/D converting unit is connected with the signal input part of microcontroller, the signal output part of microcontroller is connected with the signal input part of time delay relay, the signal output part of time delay relay is connected with the signal input part of water pump control unit, and the water pump control unit is controlled feed water pump work.
During the utility model work, by temperature detecting unit, the storage tank wall temperature is detected, testing signal is delivered to microcontroller through the A/D converting unit, when the storage tank wall temperature reaches 50 ℃, microcontroller sends control signal feed water pump control unit, and the spray thereby the startup feed water pump draws water is after the storage tank wall temperature is down to below 50 ℃ gradually, the microprocessor control feed water pump quits work, according to this circulation; In order to prevent the water pump frequent starting, be provided with time delay relay between described microcontroller and water pump control unit, the proper extension spray time makes the tank wall temperature drop to apart from 50 ℃, the certain hour interval being arranged.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in protection domain of the present utility model.
