Abstract

The utility model relates to a vertical multi-layer heat pipe water heating boiler, which is a vertical heat pipe water heating boiler using coal as fuel. Except for a heat pipe (8) transfers partial heat of fire in a first combustion chamber (1) to water in a water supply chamber, a heat pipe (13) and a heat pipe (14) also respectively transfers partial heat of the fire in a second combustion chamber (3) and partial heat of smoke gas in a smoke gas chamber (5) to the water in the water supply chamber (7). In addition, a heat pipe heat exchanger composed of a heat pipe (9), a water jacket (10), a water inlet (11) and a water outlet (12) is arranged in a fire feeding pipe (2), and the heat transferring capability of the fire to the water supply chamber (7) is enhanced.

Description

Vertical multilayer heat pipe hot water boiler

The utility model relates to a kind of heat pipe coal-fired heat pipe hot water boiler of multilayer distribution up and down.

Existing vertical heat pipe hot water boiler, stove fire flow process in boiler is short, and the efficient heat transfer function of heat pipe is failed to fill part and brought into play, and part is still filled in heat exchange inadequately, and the heat that flue gas is taken away is still more, and the thermal efficiency fails further to improve.

The purpose of this utility model provides a kind of improved vertical heat pipe hot water boiler, and it can further improve the thermal efficiency, further reduces the steel consumption of unit thermal power.

The utility model is achieved in that many heat pipes of the vertical welding of the upper wall in first combustion chamber; Many heat pipes of the vertical welding of upper wall in second combustion chamber; Many heat pipes of the vertical welding of upper wall at smoke chamber; First combustion chamber is connected by following fire tube with second combustion chamber, is being mounted with a heat exchange of heat pipe in the fire tube down; Second combustion chamber is connected by all evenly last fire tubes spaced apart in the same garden of a plurality of one-tenth with smoke chamber, and a plurality of garden tubular grid of going up the fire tubes formation are trapped among the radiating end that is welded on all heat pipes of the second combustion chamber upper wall middle; On smoke chamber, be mounted with impact tube.In first combustion chamber, a part of heat of stove fire is imported in the water in the hydroecium by the heat pipe that is welded on the first combustion chamber upper wall, heat pipe on the heat exchange of heat pipe and first chamber wall; Top in first combustion chamber, stove fire is assembled to the center, upwards enters down in the fire tube, and in following fire tube, a part of heat of stove fire imports in the interior water of hydroecium through heat exchange of heat pipe water jacket wall and the following fire tube wall that is placed in wherein; Stove fire rises from following fire tube and enters second combustion chamber, and in second combustion chamber, a part of heat of stove fire is imported in the water in the hydroecium by the heat pipe that is welded on the second combustion chamber upper wall and second chamber wall; Top in second combustion chamber, stove fire radially outward garden disperse, and rise to enter into same garden week a plurality of going up in the fire tubes evenly spaced apart, and in last fire tube, a part of heat of stove fire is in the tube wall of getting angry imports water in the hydroecium into; Stove fire in the last fire tube rises and enters smoke chamber, and stove fire was lowered the temperature and become flue gas this moment, and a part of heat of flue gas is imported in the water in the hydroecium by heat pipe that is welded on the smoke chamber upper wall and flue gas locular wall in smoke chamber; Top in smoke chamber, flue gas is assembled to the center, upwards enters impact tube and discharges.

By above heat transfer measure, improved the thermal efficiency and the thermal power of boiler, further reduced the steel consumption of unit thermal power.The vertical multilayer heat pipe hot water boiler of the utility model, the thermal efficiency can reach 85%, the steel consumption of unit thermal power has only 1/2nd of common vertical type water heater boiler, be the vertical heat pipe hot water boiler that occurs on the current market unit thermal power steel consumption amount 2/3rds.

Be equipped with and embodiment is described in further detail the utility model below in conjunction with attached.

Accompanying drawing is the profile of a kind of specification in the vertical multilayer heat pipe hot water boiler of the utility model series.

The described vertical multilayer heat pipe hot water boiler of accompanying drawing, be constructed as follows: 1 first combustion chamber (1), 1 following fire tube (2), 1 second combustion chamber (3), 16 become even last fire tube (4) spaced apart of same garden week, 1 smoke chamber (5), 1 impact tube (6), 1 hydroecium (7) that holds heated water, the upper wall vertical welding is connected to 48 heat pipes (8) in first combustion chamber (1), in following fire tube (2), be mounted with 1 by 1 heat pipe (9), the heat exchange of heat pipe that 1 water jacket (10) and 1 water inlet (11) that is communicated with hydroecium (7) and 1 delivery port (12) constitute, the vertical welding of upper wall 33 heat pipes (13) in second combustion chamber (3), evenly spaced apart 16 of same garden week go up in the middle of the formed garden of fire tube (4) tubular grid are trapped among the radiating end of all heat pipes (13), are connected to 32 heat pipes (14) at the upper wall vertical welding of smoke chamber (5);

In first combustion chamber (1), a part of heat in the stove fire is in superheater tube (8), heat pipe (9) and first combustion chamber (1) wall are passed to water in the hydroecium (7).Top in first combustion chamber (1), stove fire enters down in the fire tube (2) to center gathering and rising, and in following fire tube (2), a part of heat of stove fire imports in the interior water of hydroecium (7) through water jacket (10) wall and following fire tube (2) wall of heat exchange of heat pipe.Stove fire rises from following fire tube (2) and enters second combustion chamber (3), in second combustion chamber (3), stove fire rises and washes away the heating end of 33 heat pipes of one deck (13) that are distributed in second combustion chamber (3), by heat pipe (13) and second combustion chamber (3) wall, the heat of some stove fire is passed in the interior water of hydroecium (7) again.Top in second combustion chamber (3), stove fire radially outward garden disperses, enter into evenly spaced apart 16 of same garden week and go up in the fire tubes (4), in last fire tube (4), the heat of some stove fire is in last fire tube (4) wall imports water in the hydroecium (7) into again.Stove fire rises from last fire tube (4) and enters smoke chamber (5), this moment, stove fire became flue gas because temperature reduces, flue gas washes away the heating end of 32 heat pipes of one deck (14) that are distributed in the smoke chamber in smoke chamber (5), by heat pipe (14) and smoke chamber (5) wall, a part of heat of flue gas imports in the interior water of hydroecium (7).Top in smoke chamber (5), flue gas are assembled rising to the center and are entered impact tube (6) discharge.Like this, the stove fire in first combustion chamber (1) through the heat transfer of three heat pipe layers, has carried out heat exchange again maturely through repeatedly bent rising of analysing, and makes the thermal efficiency of the vertical multilayer heat pipe boiler of the utility model reach 85%.
