Abstract
The utility model provides a novel pipeline of liquid chlorine, manages and the inlayer pipe including outer, outer pipe with the tubular one -tenth toroidal cavity of inlayer, toroidal cavity is cut apart into the multistage by sealed ring baffle, the ring baffle relevant position the inlayer mouth of pipe is equipped with the valve, and is adjacent between the valve outer guan shangkai has PRESSURE DETECTOR, PRESSURE DETECTOR is connected with the pressure derailleur, the pressure derailleur is connected with the siren, be filled with nitrogen gas in the toroidal cavity. Set up the toroidal cavity who makes whole section pipeline through the aforesaid and become a plurality of independent units, saved the work load that the technical staff overhauld greatly. In addition, the packing of nitrogen gas is favorable to avoiding the inner tube to receive external disturbance in the cavity, and it is more stable to make chlorine carry.
Description
Technical field
The utility model relates to a kind of pipeline, especially a kind of liquid chlorine Novel delivery duct.
Background technique
Chlorine is chartreuse at normal temperatures and pressures, and be the toxic gas with intense stimulus smell, it invades human body by respiratory tract and is dissolved in the moisture contained by mucous membrane, generate hypochlorous acid and hydrochloric acid, damage is caused to upper respiratory tract mucous membrane, therefore, chlorine gas transfer process is to security requirement height very.At present, chlorine gas transfer is become liquid chlorine mainly through pressurization, is then carried by liquid chlorine cylinder, liquid chlorine tank car, also has and carries out Liquid chlorine by pipeline.Due in order to prevent it from leaking, a lot of chemical enterprise can adopt special pipeline to carry, the Chinese patent " a kind of Pneumatic conveying pipeline " being 201410148817.3 as application number discloses double-deck pipeline, although this pipeline can prevent the leakage of gas, but because the pipeline of its each section does not have independently shutoff device, so during maintenance need whole piece pipeline to close, and gas flow in whole piece pipeline still often and still may cause and leak on a large scale, so cause huge trouble for the carrying out of service work, on the other hand, cavity between this pipeline internal and external layer pipe is vacuum, and the pressure in Liquid chlorine process is 1.2MPa, internally the bearing capacity of outer layer pipe is again a huge test thus, bury huge potential safety hazard to conveying liquid chlorine.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the liquid chlorine Novel delivery duct providing a kind of easy maintenance, can open and close at any time.
For achieving the above object, the utility model provides following technological scheme: a kind of liquid chlorine Novel delivery duct, comprise external pipe and inner tube, described external pipe and described inner tube form toroidal cavity, described toroidal cavity is divided into multistage by the ring baffle sealed, the described internal layer mouth of pipe of described ring baffle relevant position is provided with valve, described external pipe between adjacent described valve has pressure detector, described pressure detector is connected with pressure transmission device, described pressure transmission device is connected with alarm buzzer, is filled with nitrogen in described toroidal cavity.
By adopting technique scheme, with ring baffle, the toroidal cavity of whole segment length is divided into some sections of independent toroidal cavities, and every segment pipe toroidal cavity is provided with independent pressure detector for detecting the pressure of toroidal cavity, again by the signal transmission of pressure transmitter, and the alarm of alarm buzzer, thus enable operator's throttle down in time, every segment pipe is made to become separate unit, and then it is just passable to make the Measuring error of pipeline only need that section of reporting to the police for alarm buzzer to carry out, and greatly saves workload.In addition, be filled with nitrogen in toroidal cavity, because nitrogen itself is more stable, and sound insulation is shockproof and the ability of heat conduction is strong, so be conducive to avoiding interior pipe to be subject to external interference, makes chlorine gas transfer more stable.
Of the present utility modelly to be set to further: every section of described external pipe has gas bleeding point, is conducive to technician like this and in time the gas in toroidal cavity is pumped, and then facilitate the carrying out of repairing work.
Described external pipe is provided with earth lead, this makes it possible to the electrostatic on pipeline all to import underground, avoids the potential safety hazard caused because of electrostatic.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of a kind of novel conveying liquid chlorine pipeline of the utility model;
Fig. 2 is the sectional view of a kind of novel conveying liquid chlorine pipeline of the utility model.
In figure: 1, external pipe; 2, inner tube; 3, toroidal cavity; 4, pressure detector; 5, manual dish valve; 6, ring baffle; 7, bleeding point; 8, earth lead; 9, pressure transmitter; 10, alarm buzzer.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.
The utility model is a kind of novel conveying liquid chlorine pipeline, this pipeline is divided into inner tube 2 and external pipe 1, toroidal cavity 3 is defined between inner tube 2 and external pipe 1, and in toroidal cavity 3, be filled with the nitrogen of a standard atmospheric pressure, because the chemical property of nitrogen is more stable, shockproof effect is good, the capacity of heat transmission is poor, and cost is low, so external pipe 1 inner and outer surface can be made almost without pressure reduction on the one hand, thus reducing the pressure-bearing load of external pipe 1, the interference can avoided extraneous heat on the other hand and clash into chlorine in inner tube 2, makes chlorine gas transfer more stable.Simultaneously, whole segment pipe toroidal cavity 3 at a certain distance is just provided with ring baffle 6, the toroidal cavity 3 of whole segment pipe has been separated into the independent toroidal cavity 3 of some sections by ring baffle 6, moreover be provided with manual dish valve 5 in the inner tube 2 of ring baffle 6 relevant position, external pipe 1 has pressure detector 4, pressure detector 4 is connected with pressure transmitter 9, pressure transmitter 9 is connected with alarm buzzer 10, when pressure detector 4 detects the pressure increase in toroidal cavity 3, will Signal transmissions to pressure transmitter 9, pressure transmitter 9 is by contrasting the signal received and setting value, when the signal accepted has exceeded the value of setting, then pressure transmitter 9 will pass to alarm buzzer 10 signal, after alarm buzzer 10 gives the alarm, technician can close Hand-operated butterfly valve 5 in time, at this pressure detector 4, the specific works principle of pressure transmitter 9 and alarm buzzer 10 is all prior art, substantial progress is not had to the technological scheme of this section, so be no longer explained in detail.Thus substantially increase the efficiency of reply Liquid Chlorine Leakage Accident on the one hand, it also avoid the maintenance of technician to whole piece pipeline on the other hand, greatly reduce the workload of maintenance.
Further scheme is that every section of external pipe 1 has bleeding point 7, when liquid chlorine occurs to leak, and the gas that repair personnel can be found time in correspondent section pipeline in time by bleeding point 7, thus more effective pipeline to be rushed to repair.On the other hand, external pipe 1 is also provided with earth lead 8, like this once pipeline create electrostatic will be directed to underground immediately, avoids and makes conveying liquid chlorine produce potential safety hazard because of electrostatic cause.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
