Abstract
The utility model discloses an ethylene oxide cooling device, which comprises a refrigerating unit and an ethylene oxide storage tank, wherein the ethylene oxide storage tank is arranged in a safety zone; a cooler is arranged in the ethylene oxide storage tank; and the refrigerating unit and the cooler are connected through a pipeline. The ethylene oxide cooling device is characterized in that the return section of the pipeline is connected with a pipeline pump in series. According to the ethylene oxide cooling device disclosed by the utility model, the flow speed of the return section of a cooling medium is increased, so that the temperature of the cooling medium returning to the refrigerating unit tends to be consistent with the temperature of the cooling medium actually coming out of the cooler, so that the refrigerating unit can be normally started, and the energy consumption is reduced.
Description
Technical field
The utility model relates to the cooling device apparatus field, particularly a kind of oxirane cooling device.
Background technology
Oxirane is the important materials of Chemical Manufacture, mainly for the manufacture of ethylene glycol (polyester fiber raw materials processed), synthetic detergent, non-ionic surface active agent, antifreeze, emulsifying agent and condensed ethandiol series products, also for the production of plasticizer, lubricant, rubber and plastics etc., but the inflammable and explosive property of oxirane needs it is taked cooling measure in storage process.Existing oxirane cooling device comprises the freezing unit that is arranged on the cooler in the oxirane storage tank and cold is provided to cooler, if freezing unit is arranged on the place of close epoxy storage tank, need carry out explosion-proof processing to freezing unit and electric control system, this will cause the investment of whole oxirane aggregate-storing system to increase.For this reason, producer generally can be arranged on freezing unit and corresponding electric control system beyond the complete zone of oxirane storage tank, relies on pipeline to be connected with cooler in the storage tank, invests with reduction.But such mounting means can bring a problem, because pipeline is generally longer, it is longer that cooling medium is got back to time of freezing unit, and cooling medium can bring loss of refrigeration capacity in the flow process in pipeline, cause the actual coolant temperature that comes out of the coolant temperature of getting back to freezing unit and cooler inconsistent, make and improved energy consumption by freezing unit frequent starting.
The utility model content
The purpose of this utility model is to provide a kind of oxirane cooling device that can reduce explosion-proof cost and good cooling results, to address the above problem at high deficiency and the defective of antiknock device cost of existing oxirane cooling device.
The technical problem that the utility model solves can realize by the following technical solutions:
The oxirane cooling device, comprise freezing unit and the oxirane storage tank that is arranged in the safety zone, in described oxirane storage tank, be provided with cooler, be connected by pipeline between described freezing unit and the described cooler, it is characterized in that, at backhaul section series connection one tubing pump of described pipeline.
Owing to adopted above-mentioned technical scheme, the utility model has improved the flow velocity of cooling medium backhaul section, the actual coolant temperature that comes out of the coolant temperature of getting back to freezing unit and cooler is reached unanimity, make that freezing unit starting is normal, reduced energy consumption.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to shown in Figure 1, the oxirane cooling device comprises freezing unit 100 and oxirane storage tank 200, oxirane storage tank 200 is installed in the safety zone 400, freezing unit 100 is installed in outside the safety zone 400, therefore freezing unit 100 need not to dispose special anti-explosion safety equipment, reduces the investment of freezing unit 100.
Cooler 110 is installed in oxirane storage tank 200, cooler 110 is cooling coil, the two ends of cooling coil are respectively by going journey pipeline 101 to be connected with refrigerator 100 with backhaul pipeline 102, in return conduits 102 tubing pump 300 is installed, to accelerate the flow velocity of cooling medium in the backhaul pipeline, the actual coolant temperature that comes out of the coolant temperature of getting back to freezing unit and cooler is reached unanimity, make that freezing unit starting is normal, reduced energy consumption.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
