Description
Technical field
The utility model relates to a kind of refrigeration unit protective device, realizes controlling the device of protection refrigeration unit specifically by the density that detects freezing liquid.
Background technology
In chemical process; same equipment often switches the various heat exchange medium because of the different needs of technological requirement; if use recirculated cooling water to switch to freezing liquid then earlier; usually can recirculated cooling water be transported to the freezing liquid storage tank because of misoperation; cause freezing liquid constantly to be diluted, long-term accumulation will greatly damage the operating efficiency and the service life of freezing unit.At present, can play the gamma-rays on-line measuring device of refrigeration unit protective effect, cost an arm and a leg, the operation more complicated for some medium-sized and small enterprises, is difficult to burden, is difficult for using.Therefore, designing a kind of refrigeration unit protective device simple in structure, easy to use, that production cost is low is the technical problem that needs to be resolved hurrily.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of refrigeration unit Density Detection protective device is provided, and its project organization is simple, easy and simple to handle, production cost is low, result of use is good.
For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of refrigeration unit Density Detection protective device, it comprises feed liquor motor-driven valve, freezing liquid storage tank, freezing liquid circulating pump and circulation electric valve, at freezing liquid storage tank liquid feeding end device for detecting density is set, described device for detecting density comprises the glass density meter; The densitometer sleeve pipe that glass density meter outer setting is connected with the freezing liquid storage tank; Densitometer sleeve pipe top is provided with photoelectric tube, and described photoelectric tube is connected with the circulation electric valve with the feed liquor motor-driven valve respectively; Described glass density meter top is provided with the aluminium-foil paper that floating position is positioned at the photoelectric tube top.
Above-mentioned refrigeration unit Density Detection protective device, its densitometer sleeve pipe top are provided with the detection liquid outlet that is connected with the freezing liquid storage tank; Densitometer sleeve pipe bottom is provided with detects the liquid import; Be provided with the densitometer control valve at detection liquid import front end.
Refrigeration unit Density Detection protective device of the present utility model is intended to protect the freon refrigeration unit that uses in the chemical process, is particularly useful for the refrigeration unit that freezing liquid is salt solution or ethylene glycol solution.By the density of online detection freezing liquid, the self-protection function of freezing unit avoids damaging freezing unit when realizing the freezing liquid low-density, effectively prolongs its service life.
The utility model also has the following advantages and beneficial effect: project organization is simple, easy and simple to handle, fault rate is low; Production cost is low, result of use good.The gamma-rays on-line measuring device price of at present commercially available effect same is about 2-3 is ten thousand yuan, and as seen this covering device total price has tangible price advantage only in 2000 yuan, has good marketing prospect.
Description of drawings
Fig. 1 is a working state schematic representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, refrigeration unit Density Detection protective device of the present utility model, it comprises feed liquor motor-driven valve 2, freezing liquid storage tank 9, freezing liquid circulating pump 10 and circulation electric valve 11, at freezing liquid storage tank 9 liquid feeding ends device for detecting density 14 is set, and device for detecting density comprises glass density meter 6; The densitometer sleeve pipe 7 that glass density meter 6 outer setting are connected with the freezing liquid storage tank; Densitometer sleeve pipe 7 tops are provided with photoelectric tube 3, and photoelectric tube 3 is connected with circulation electric valve 11 with feed liquor motor-driven valve 2 respectively; Glass density meter 6 tops are provided with the aluminium-foil paper 5 that floating position is positioned at photoelectric tube 3 tops.Densitometer sleeve pipe 7 tops are provided with the detection liquid outlet 8 that is connected with freezing liquid storage tank 9; Densitometer sleeve pipe 7 bottoms are provided with detects liquid import 13; Be provided with densitometer control valve 4 at detection liquid import 13 front ends.
During use, the freezing liquid in the freezing liquid storage tank 9 flows out through freezing liquid circulating pump 10, enters refrigeration unit 12 coolings through circulation electric valve 11, enters chemical industry equipment 1 heat exchange again after feed liquor motor-driven valve 2 is back to freezing liquid storage tank 9.Wherein, the part freezing liquid steadily enters the densitometer sleeve pipe 7 of PPR material through densitometer control valve 4, and freezing liquid storage tank 9 is flowed back in liquid outlet 8 after testing again.Under the normal condition, aluminium-foil paper 5 positions on the glass density meter 6 are than photoelectric tube 3 position height, and no signal is fed back, and equipment is in the even running state.
When chemical industry equipment 1 is caused recirculated cooling water to sneak into the freezing liquid system by maloperation; when freezing liquid density is descended; glass density meter 6 can and descend along with the reduction of freezing liquid density; this moment, the aluminium foil 5 on glass density meter 6 tops maintained an equal level with photoelectric tube 3 positions; produce signal feedback; motor-driven valve 2 and motor-driven valve 11 are closed, and freezing unit 12 also can be because of no freezing liquid flow autostop, thereby reaches the purpose of protection refrigeration unit.This device can also be used with autoalarm, is convenient in time remind freezing unit attendant to adjust the freezing liquid proportioning, safeguards the even running of production process.
The above, it only is preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
