Abstract

A bitumen heating apparatus of two-phase closed thermosyphon comprises a bitumen heating tank 1, a fire flue 2, a smoke flue 4, an induced draft fan 3, a heating furnace 7 and a heat pipe 5. The heating apparatus has the advantages that the heating technology smartly integrates the storage and heating of the bitumen and the heat source; compared with the heating mode of heat conducting oil furnace, the initial investment is far less; meanwhile, the bitumen heating apparatus of two-phase closed thermosyphon uses heat transfer technology and tank within tank technology to heat partial bitumen up to 180 DEG C in extremely short time (from 18 DEG C to 180 DEG C in less than one hour); the bitumen heating apparatus is able to heat and prepare bitumen for construction on the same day, ensuring that the hot bitumen construction is carried out on fine days, thus greatly improving the construction quality and saving the energy; the bitumen heating apparatus only consumes 20 kg coal when heating one ton of bitumen, saving coal by 96 percent.

Description

The two-phase closed type hot siphon asphalt heater

Technical field

The utility model relates to asphalt heating equipment, specifically a kind of two-phase closed type hot siphon asphalt heater.

Background technology

In China, following several forms are adopted in the pitch heating nothing but:

A, naked light heating: this kind mode of heating, the thermal efficiency are extremely low, and environment is polluted, and are a kind of mode of heatings that is eliminated but is using at a lot of road teams at present.

B, Steam Heating: pitch supply factory's (station) that the 60 to 70's of eighties of last century builds, what all adopt basically is this kind mode of heating.But this kind mode thermal efficiency tableland (below 30%), firing rate is too slow, and environment pollution is bigger, and during equipment operation is in, low-pressure state, operating personnel need through the special training of labour protection department.Newly-built asphalt heating equipment does not adopt this kind mode of heating basically now.

C, heat-conducting oil heating: this kind mode of heating just rises in China at the eighties of last century early eighties, but obtain popularizing and having formed the gesture that replaces other mode of heatings in pitch heating field very soon, be characterized in normal pressure, high temperature, thereby thermal efficiency height, firing rate are fast, environment pollution is little, and pitch can be heated to any temperature below 180 ℃.But it is bigger that its shortcoming is an one-time investment, and heating needs the whole system operation at every turn, and the hair oil amount is too little, and economic benefit is not high.

D, Electric heating: this kind mode of heating, be characterized in that thermal efficiency height, firing rate are fast, do not have environment pollution, one-time investment is few, but pitch per ton heating expense is higher.

E, solar energy heating mode: this kind mode energy-saving effect is best, the environment pollution minimum, but its one-time investment is bigger, and only be fit to the area that the duration of sunshine is long and arid is short of rain.

Summary of the invention

The purpose of this utility model is that design is a kind of simple in structure, and power consumption is few, and cost is low, and it is fast that pitch is dissolved in heating, uses two-phase closed type hot siphon asphalt heater extremely easily.

The utility model two-phase closed type hot siphon asphalt heater comprises: heating furnace, heat pipe, flue, quirk, air-introduced machine, Asphaltum heating pot, pitch oil-out, expansion slot.

Divide high-temperature region, low-temperature space, middle warm area in the Asphaltum heating pot, a large amount of heat pipes are housed in the high-temperature region, pitch is heated up rapidly, also be furnished with suitable heat pipe in the middle warm area, pre-heated bitumen can flow automatically it to the high-temperature region, the exchange heat of high-temperature region is to low-temperature space, pitch that can the preheating low-temperature space.

One of pitch oil-out is exposed at outside the Asphaltum heating pot, and the other end is contained in the top of the high-temperature region in the Asphaltum heating pot.

Heat is absorbed by two-phase closed type hot siphon in quirk, and in high-temperature region and middle warm area, two-phase closed type hot siphon dispels the heat rapidly, adds heated bitumen.Its core be exactly superconduction goods and materials in the two-phase closed type hot siphon in quirk, external temperature is higher than superconduction liquid, superconduction liquid absorbs the heat vaporization rapidly, air-flow rises, and in high-temperature region and middle warm area, external temperature is lower than superconduction gas, the superconduction gas heat that sheds rapidly, liquefying falls for drop.Go round and begin again, with the exchange heat in the quirk to the high-temperature region or middle warm area.

The advantage of the utility model two-phase closed type hot siphon asphalt heater is: this kind heating technique is melted into a whole the storage heating and the thermal source of pitch cleverly, one-time investment is compared the heat-conducting oil furnace mode of heating and will be reduced a lot, simultaneously, the use of jar technology in two-phase closed type hot siphon asphalt heater heat transfer technology and the jar, can also be in the extremely short time pitch of part be warming up to 180 ℃ (18 ℃～180 ℃ are less than 1 hour), can heat the same day, construction on the same day, the construction of assurance heated bitumen is carried out at fine day, thereby improve workmanship greatly, saved the energy widely, one ton of pitch only use 20kg coal of this device heating can be saved coal 96%.
