The utility model is characterized in that a set of helical heaters comprising protecting sleeve tubes and heating elements is adopted to heat by being immersed under the liquid level; the heat efficiency can reach 74% above. The utility model has the advantages of low energy consumption, simple structure, easy fabrication, safety, easy installation, labor condition improving, etc.

Description

Internal-heating hydrochloric acid heating unit

The invention belongs to resistance internal heat type heater.

During chemical reagent was produced, the purification of a lot of kinds all will be adopted distillation, evaporation technique.At present, in the production of reagent hydrochloric acid, the overwhelming majority is placed on raw material acid in the flask, carries out outer heating with electric furnace pan, and the heat efficiency generally about 25%, often will be changed stone or metal plate for standing a stove on as a precaution against fire, stove silk, operates arduous dangerous again.

The present invention be directed to the problems referred to above and develop, be intended to realize energy-conservationly, and, fully prolong the life-span of heating element by means of the advantage of internal heat type by improving the heat efficiency.

The design feature of this device mainly is to adorn resistance wire within the multi-circle spiral flow glass tube, fills the transformer oil crossed with ageing or silicone oil, conduction oil in the pipe.Connection clamp is adopted in the joint of resistance wire and power supply lead wire, and is installed on the horizontal level of upper strata helix tube.Resistance wire power is 1500W, and operating voltage is 220V(AC), the material of transparent glass tube can adopt 95 material, expect or quartz glass for ten No. seven, to help thermal radiation, adopting the purpose of helix tube heating, is to produce the high-temperature region at the helix tube center, strengthens liquid convection.

This installs in the reagent hydrochloric acid production at home precedent as yet.

Adopt this device that following characteristics are arranged:

1, the heat efficiency can be brought up to more than 74% by original 25%;

2, the heater element life-span was grown several times more originally;

3, make easily, cost is very low;

4, installation is as easy as rolling off a log, only opens two new holes on the plug of original flask and gets final product;

5, change this heater after, can make original flow process production capacity improve more than 50%;

6, working condition is improved greatly.

For example: utilize said apparatus to produce reagent hydrochloric acid, raw material acid concentration 31%, finished product reagent hydrochloric acid concentration is 38%, single group output is 2.4 kilograms/hour, power consumption is 1.25 degree/kilogram reagent hydrochloric acids, and present domestic level is 3～4 degree/kilogram reagent hydrochloric acids, and product economize on electricity promptly per ton can reach more than 2500 degree.

Claims (4)

1, a kind of electrical heating method is produced the energy saver of chemical reagent, it is characterized in that being done by glass tube the oil immersed type resistance heater of outer jointing jacket.

2, energy saver according to claim 1 is characterized in that doing heating element with resistance wire.

3, energy saver according to claim 1 is characterized in that making protective casing with the spirality transparent glass tube, and its material can be 95 glass or 17 flint glass Fs or quartz glass.

4,, it is characterized in that pouring into the transformer oil of seasoned mistake or silicone oil, conduction oil according to the said energy saver of claim 1.
