Description
Technical field
The utility model relates to 3,4-dichlorophenyl isocyanate production field, is specifically related to a kind of production for 3,4-dichlorophenyl isocyanate and uses toluene safe recovery device.
Background technology
3,4-dichlorophenyl isocyanate production plant is provided with toluene scale tank, toluene recovery groove, if toluene storage tank local leakage, after storage tank leaks, inflammable medium forms liquid pool, and evaporation forms vaporous cloud, inducible damage sequence mainly contains the serious consequence such as pond fire, vaporous cloud blast, adds the danger of Workshop Production.
Utility model content
For above problems of the prior art, the utility model provides a kind of 3,4-dichlorophenyl isocyanate production and uses toluene safe recovery device, avoids the serious consequence of evaporating the blast forming vaporous cloud generation after toluene leaks.
The utility model is achieved through the following technical solutions:
A kind of,-dichlorophenyl isocyanate is produced and is used toluene safe recovery device, include workshop body, outside the body of described workshop, cooling tank and withdrawing can are set, body top, described workshop sets out gas port, described air outlet sets out feed channel, the outlet side of described outlet pipe is arranged on the sidewall in the middle part of cooling tank, and described outlet pipe communicates with described cooling tank, the bottom of described cooling tank arranges liquid outlet, described liquid outlet is arranged fluid pipeline, the outlet end of described fluid pipeline is arranged on the top of described withdrawing can, and described fluid pipeline communicates with described withdrawing can, described outlet pipe is arranged blower fan and valve, described fluid pipeline arranges water pump and valve, above the junction being positioned at described outlet pipe and described cooling tank in described cooling tank, stratum reticulare is set, the top being positioned at described stratum reticulare in described cooling tank arranges disc type cooling tube.
Further, described workshop inner body wall arranges heating tube, the lower surface of described stratum reticulare arranges at least two equally distributed tapered columns.
The beneficial effects of the utility model are: the serious problems of the vaporous cloud blast produced after leaking for existing technology toluene, adopt the mode being connected with retrieving arrangement at production plant, therefore just the vaporous cloud that the toluene of accidental release is formed can be recovered in withdrawing can, avoid after toluene leaks and evaporate the serious consequence forming the blast that vaporous cloud produces, therefore just improve the security of Workshop Production and the problem of timely treatment plant toluene leakage, provide cost savings simultaneously, benzene can be utilized again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of disc type cooling tube.
In figure: 1 is workshop body; 2 is cooling tank; 3 is withdrawing can; 4 is air outlet; 5 is outlet pipe; 6 is liquid outlet; 7 is fluid pipeline; 8 is blower fan; 9 is water pump; 10 is stratum reticulare; 11 is disc type cooling tube; 12 is heating tube; 13 is tapered column; 14 is valve.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of 3, 4-dichlorophenyl isocyanate is produced with toluene safe recovery device structure iron, include workshop body 1, cooling tank 2 and withdrawing can 3 are set outside described workshop body 1, body 1 top, described workshop sets out gas port 4, described air outlet 4 sets out feed channel 5, the outlet side of described outlet pipe 5 is arranged on the sidewall in the middle part of cooling tank 2, and described outlet pipe 5 communicates with described cooling tank 2, the bottom of described cooling tank 2 arranges liquid outlet 6, described liquid outlet 6 arranges fluid pipeline 7, the outlet end of described fluid pipeline 7 is arranged on the top of described withdrawing can 3, and described fluid pipeline 7 communicates with described withdrawing can 3, described outlet pipe 5 is arranged blower fan 8 and valve 14, described fluid pipeline 7 is arranged water pump 9 and valve 14, be positioned in described cooling tank 2 above described outlet pipe 5 and the junction of described cooling tank 2 and stratum reticulare 10 is set, the top being positioned at described stratum reticulare 10 in described cooling tank 2 arranges disc type cooling tube 11, cooling performance is faster and better.
Please refer to Fig. 1, preferably, described workshop body 1 inwall arranges heating tube 12, the lower surface of described stratum reticulare 10 arranges at least two equally distributed tapered columns 13, is easier to the liquid drippage formed, therefore accelerates the liquefaction of gas benzene.
After toluene leaks, open the blower fan on outlet pipe and valve, the intrinsic heating tube heat temperature raising in workshop, in workshop, benzene forms gas or steam cloud, after the vaporous cloud formed in production plant is transported in cooling tank by outlet pipe, after gas cooling in cooling tank is become liquid by the disc type cooling tube cooling in cooling tank, most of liquid drops onto cooling tank bottom by stratum reticulare being arranged tapered column, then water pump and valve is opened by Liquid transfer in withdrawing can, tapered column 13, be easier to the liquid drippage formed, therefore the liquefaction of gas benzene is accelerated, therefore the safety of human body is ensured like this, recovering effect is very good, add the security in workshop, the serious problems of the vaporous cloud blast produced after leaking for existing technology toluene, adopt the mode being connected with retrieving arrangement at production plant, therefore just the vaporous cloud that the toluene of accidental release is formed can be recovered in withdrawing can, avoid after toluene leaks and evaporate the serious consequence forming the blast that vaporous cloud produces, therefore just improve the security of Workshop Production and the problem of timely treatment plant toluene leakage, provide cost savings simultaneously, benzene can be utilized again.
The serious problems of the vaporous cloud blast that the utility model produces after leaking for existing technology toluene, adopt the mode being connected with retrieving arrangement at production plant, therefore just the vaporous cloud that the toluene of accidental release is formed can be recovered in withdrawing can, avoid after toluene leaks and evaporate the serious consequence forming the blast that vaporous cloud produces, therefore just improve the security of Workshop Production and the problem of timely treatment plant toluene leakage, provide cost savings simultaneously, benzene can be utilized again.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
