Abstract
An efficient vacuum furnace comprises a furnace body, a burner, and a smoke flue. The smoke flue is of vertical pipe type, and the smoke tube radiation segment part is vertical to the medium flowing tube which is axially inserted and is upper and lower connected, and the heat transfer medium is arranged in the clearances between the tubes. Pipes with heated medium inside are arranged on the furnace body, and the inside of the heat transfer medium is provided with passivant solution and special refrigerant. The utility model has the advantages of unique structure, and the thermal efficiency is greatly improved, and many kinds of fuels can be applied.
Description
Technical field
The utility model relates to a kind of high-efficiency vacuum heating furnace.
Background technology
Vacuum furnace is to be heat transfer medium with water, become steam after being heated, steam removes heat medium, and condensation own utilizes the latent heat of phase transformation, the gas-liquid reciprocation cycle, by improving the heat transfer coefficient of coil pipe, improve heat-transfer effect, but produce on-condensible gas at work and have corrosion and the dissolving of water the shell material, therefore, effect is still undesirable.
Summary of the invention
The purpose of this utility model provides a kind of high-efficiency vacuum heating furnace, this furnace structure uniqueness, and its thermal efficiency improves greatly, and can use pluralities of fuel.
For achieving the above object, the present invention takes following design: this high-efficiency vacuum heating furnace comprises: body of heater, burner, flue, flue is upright calandria, the media flow pipe that the insertion perpendicular to axial direction of smoke pipe radiant section portion is communicated with up and down, heat transfer medium is placed in the gap between pipe, the comb that heated medium is arranged in upper of furnace body is provided with is added with passivating solution and extraordinary working medium in the described heat transfer medium.
The utility model has the advantages that: the structure uniqueness, its thermal efficiency improves greatly, and can use pluralities of fuel.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A sectional drawing of Fig. 1
The specific embodiment
As shown in Figure 1,1 for being built in the burner of body of heater bottom in the utility model, and 2 is that stokehold brick, 3 is flue, and flue is a two-layer structure, smoke pipe radiant section portion (one deck) can parallelly establish several groups for the media flow pipe 20 that upright calandria, the insertion perpendicular to axial direction of smoke pipe radiant section portion are communicated with up and down.5 is that back smoke box, 17 is respectively heating and uses water coil for extraordinary working medium, 10,11 for passivating solution, 9 for blowoff valve, 8 for chimney, 4 for front smoke box, 16; 12,13,14 be respectively pressure protective device; electromagnetic valve; vacuum valve; 18 is ash removing opening; 15 is vacuum meter, and the utility model can be provided with the pressure and temp equal controller.
In the utility model, insert flow duct in the smoke pipe (flue), can make about the heat transfer medium perforation, smoke pipe can be two-layer or individual layer, and the radiant section portion of the flue pipe end, is near bottom of furnace body, its height b from the bottom is the 40-50 centimetre, outside used medium dewaters, also have extraordinary working medium, passivating solution is: phosphate, silicate, chromate, the 3-10% aqueous solution (wt%) passivating solution of salts such as nitrite can be prevented the furnace wall corrosion, improves heat transfer efficiency, described extraordinary working medium market is on sale, the trade mark is DT-1 type (Beijing entropy Yueda Energy Science Co., Ltd product), for example adopts to add potassium bichromate 3-6g, sodium dichromate 5-17g in the 100g water.BeO 6-9g, cobalt blue 1-5g, dysprosia 3-5g, zirconium dioxide 20-25g, strontium chromate 30-32g, mangano-manganic oxide 22-23g.
