Description

Heat pipe boiler

Technical field

The utility model relates to a kind of heat exchanger, especially a kind of heat pipe boiler that utilizes heat pipe to carry out exchange heat.

Background technology

In the pyrite-based sulfuric acid production device, often adopt fluidized bed roasting, waste heat boiler recovery used heat, electric cleaner to gather dust cooling tower-scrubbing tower-two-stage electrostatic precipitator acid-scrubbing cleaning, the technological process of " 3+1 " double-absorption.Because the operating mode of calcining process is very abominable, the one, furnace gas temperature is not high, and general waste heat boiler outlet furnace gas temperature is generally 350～400 ℃, and electric cleaner outlet furnace gas temperature is generally about 320 ℃, there is dew point corrosion danger in equipment, must control furnace gas more than 220 ℃; The 2nd, furnace gas dustiness height, particularly waste heat boiler outlet dustiness have greater than 200g/m ³, flue dust sticks easily, occluding device; The 3rd, can utilize the temperature difference less, particularly the electric cleaner outlet can utilize the temperature difference only about 100 ℃.Therefore, want to reclaim this part heat and must consider the laying dust of equipment, wearing and tearing and dew point corrosion problem, selection can realize the heat transmission equipment of heat exchange fast.

The utility model content

The purpose of this utility model just provides a kind of anti-laying dust wearing and tearing and dew point corrosion, can realize the heat exchanger of heat conversion fast.

The technical solution adopted in the utility model is: heat pipe boiler, it is characterized in that it comprises housing, is positioned at sealed water jacket and heat pipe that the housing top links to each other with housing, described heat pipe top is positioned at water jacket, the lower part is positioned at housing, the housing left and right sides is respectively equipped with gas approach and exhanst gas outlet, described heat pipe comprises shell, capillary wick and is adsorbed on liquid medium in the capillary wick, heat pipe is a sealed tube, inside is vacuum, capillary wick is attached on the heat pipe inwall, and the centre is the cavity that steam flows; The outside of described heat pipe is connected with several and is used for increasing the fin of inhaling the heat release area.

Adopt technique scheme, high-temperature flue gas enters from the housing gas approach, discharges from exhanst gas outlet, and water jacket and water source join.After high-temperature flue gas enters, the heat pipe that is arranged in housing will absorb the heat of flue gas, the tube wall that heat passes shell heats up the liquid medium in the capillary wick, when liquid medium reaches vapourizing temperature, liquid medium will be vaporized into steam, rise along cavity, arrival is positioned at the heat pipe section of water jacket, being subjected to cooling makes the steam condensation become liquid, liquid is back to the part that heat pipe is positioned at cavity of resorption under the effect of capillary force in capillary wick, circulation continuously reaches the other end with heat from an end so repeatedly.

As further improvement of the utility model, it also comprises drum, and water jacket is communicated with the drum pipe by steam pipe, constitutes closed circuit.By drum steam is controlled discharging and constitute closed circuit.

The utility model beneficial effect is: 1, because Heat Transfer of Heat Pipe on Heat Pipe is to utilize heat pipe inner fluid collection attitude to change to conduct heat, the hot side of heat pipe adopts the high-frequency welding fin reinforcing to conduct heat, the heat transfer efficiency height, and hot collateral resistance is little, compact equipment, little, the light weight of volume.2, heat pipe boiler can recently change external condition by the length of choose reasonable cooling section and bringing-up section, can regulate the operating temperature and the bringing-up section tube wall temperature of heat pipe within the specific limits, thereby effectively prevent dew point corrosion.3, separate between heat pipe in the system, single or several heat pipe failure or damage do not influence the safe operation of whole device, and just heat exchange area reduces security of system performance height; This point seems particularly important for the quantity-produced device, can therefore not cause device to stop.4, good isothermal, the working solution purity height of inside heat pipe, the boiling of inside heat pipe and condensation process, be constant temperature be again the process of constant voltage, so bringing-up section and cooling section all are the zones of constant temperature.5, because the heat-pipe elements of heat exchange of heat pipe is independent the installation, and simple in structure, the quantity of heat-pipe elements can increase and decrease according to the heat exchange amount, can change separately simultaneously.6, consider that fume content is higher, strengthen the heat pipe spacing, and adopt the design of shock wave deashing, to reduce the influence that flue dust brings in heat pipe evaporator heat pipe section.
