Description

A kind of Full automatic heat conductive oil temperature controller

Technical field

The utility model relates to a kind of heat-conducting oil heating control appliance, particularly a kind of Full automatic heat conductive oil temperature controller.

Background technology

Along with industrial development and scientific and technical progress, organic heat carrier furnace has obtained continuous development and application.Although the operating pressure of organic heat carrier furnace is lower, in stove, the heat transfer oil temperature is high, and mostly has inflammable and explosive characteristic, once be in operation, leaks, and will cause the accidents such as fire, blast, even causes casualties and property loss.Therefore, to safe operation and the management of organic heat carrier furnace, must pay much attention to.Electric heater for heat conduction oil is a kind of novel, safe, energy-efficient, and low pressure (under normal pressure or lower pressure) also can provide the extraordinary industrial furnace of high temperature heat, take conduction oil as heat carrier, by hot oil pump, makes the conduction oil circulation, transfers heat to the hot equipment of using.

Electric heater for heat conduction oil is given with hot equipment after heating a period of time, by the conduction oil temperature in hot equipment, can reduce, lower than the value of setting, use the hot equipment can't normal heating, therefore must guarantee with the conduction oil temperature stabilization in hot equipment in the temperature range of setting, existing Temp. control method is generally by with in hot equipment, temperature inductor being installed, add electrically-controlled valve or pneumatic operated valve at boiler with between with hot equipment, in the certain limit that temperature reduces, controlling motor-driven valve or pneumatic operated valve opens, high temperature oil in boiler enters with in hot equipment, and flow back in boiler with the low temperature oil in hot equipment, realize the control of temperature, this Temp. control method, when motor-driven valve or pneumatic operated valve are closed, with the conduction oil in hot equipment, will not circulate, form dead oil, because high temperature oil and low temperature oil fail fully to mix, cause the temperature imbalance, not only reduce heat conduction efficiency, can cause with the oil guide pipe local heating of hot equipment is inhomogeneous simultaneously and cause being out of shape explosion, conduction oil is with not being flowing in for a long time the Oil Guide tube wall in hot equipment, not there will be coking phenomenon, and along with thickening of coking, the higher formation that promotes again coking of oil guide pipe wall temperature, make the oil guide pipe deterioration of safety, the accident of may blasting at any time, and heat conduction has for a long time and do not circulate, will make the conduction oil quality reduce, viscosity increases.

The utility model content

The utility model proposes a kind of Full automatic heat conductive oil temperature controller, realized the stable control to the conduction oil temperature, impel with the conduction oil in hot equipment simultaneously and circulate, avoid forming dead oil and cause the problems such as the hot equipment oil guide pipe of the even use of uneven heating coking.

The technical solution of the utility model is achieved in that

A kind of Full automatic heat conductive oil temperature controller, comprise oil tank, circulating pump, controller, triple valve and boiler oil inlet pipe, and described boiler oil inlet pipe is communicated with described oil tank; The lower valve port of described triple valve is communicated with described oil tank, and two side valve mouths of described triple valve are connected with respectively boiler oil return pipe for being communicated with boiler and for the equipment oil return pipe with being communicated with hot equipment; Described boiler oil return pipe and described equipment oil return pipe are communicated in respectively the two ends of described oil tank; The oil-in of described circulating pump is communicated with described oil tank; The oil-out of described circulating pump is equipped with temperature inductor, and described temperature inductor is connected with described controller, and described controller is connected with described triple valve.

Further, described triple valve is Pneumatic three-way valve or electric T-shaped valve.

Further, the oil-in of described circulating pump is connected in the left end of described oil tank by a communicating pipe.

To description of the present utility model, compared to the prior art, the utlity model has following advantage from above-mentioned:

The utility model utilizes circulating pump, triple valve etc. to form the Full automatic heat conductive oil temperature controller, utilize this temperature controller, when temperature lower than when setting value, controller is controlled triple valve and is opened, high temperature heat conductive oil in boiler enters in the oil tank of temperature controller, and the low temperature conduction oil in oil tank is back in boiler, make the conduction oil temperature in the temperature controller oil tank raise; Simultaneously, circulating pump sends into the conduction oil in oil tank with in hot equipment, and be back in oil tank with the conduction oil in hot equipment, when triple valve is closed, with the conduction oil in hot equipment still under the drive of circulating pump and oil tank in oil constantly circulate, make with hot equipment and be heated evenly, and avoid dead oil to cause the phenomenon of coking.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
