Fig. 1 is structural representation of the present utility model,

Fig. 2 is left view of the present utility model,

Fig. 3 is vertical view of the present utility model.

The specific embodiment:

Referring to Fig. 1-3, this specific embodiment by the following technical solutions: it comprises gas approach 1, exhanst gas outlet 2, water tank bottom plate 3, water inlet 4, coaming plate 5, shroud ring reinforcement 6, top board 7, heat pipe 8, water tank 9, smoke box 10, shoot door 11, ash dropping hopper 12, delivery port 13, evacuation port 14, thermometer 15 and sewage draining exit 16; Smoke box 10 is arranged on the bottom of water tank 9, smoke box 10 is connected by heat pipe 8 with water tank 9, gas approach 1 is arranged on the left side of smoke box 10, exhanst gas outlet 2 is arranged on the right side of smoke box 10, water tank bottom plate 3 is arranged on the bottom of water tank 9, heat pipe 8 is weldingly fixed on the base plate 3, water inlet 4 is arranged on the front portion of water tank 9, coaming plate 5 is arranged on the inboard of water tank 9, shroud ring reinforcement 6 is arranged on the outside portion of water tank 9, top board 7 is arranged on the top of water tank 9, and shoot door 11 is arranged on the front portion of smoke box 10, and ash dropping hopper 12 is arranged on the bottom of smoke box 10, delivery port 13 is arranged on the rear side of water tank 9, evacuation port 14 is arranged on the top of water tank 9, and thermometer 15 is arranged on the right upper portion of water tank 9, and sewage draining exit 16 is arranged on the bottom of water inlet 4.

The operation principle of this specific embodiment is: tubular boiler economizer body is divided into two parts up and down, and top is divided into storage tank, and the bottom is divided into smoke box; Two parts are connected by super heat-conductive pipe up and down, and the heat pipe-type of lower part is heat absorbing end, contacts with boiler smoke; The heat pipe on top contacts with water in the water tank; Therefore when boiler smoke washed away the heat pipe heat absorbing end, the superconductive medium of inside heat pipe will be vaporized, and rises to heat release section, and the heat release section tube wall of heat pipe is outward water, met coldly with heat release, and medium will liquefy again and get back to heat absorbing end with the gravity effect again simultaneously.By the circulating phase-change process heat energy in the flue gas is fully absorbed, the water in the water tank is constantly heated, thereby the supply boiler has improved the thermal efficiency of boiler greatly.Thereby because forthright volume and the resistance that reduces equipment greatly of heat transfer efficient of super heat-conductive pipe, and there is the microseismic activity function to greatly reduce the workload of deashing under the heat pipe ruuning situation, the smoke box bottom is provided with ash dropping hopper simultaneously, the smoke box both sides also are provided with shoot door, therefore the deashing problem has just thoroughly solved, and the employing of tubular boiler economizer is heat pipe heat exchanging, and heat pipe is separate work, gone bad and also can not have influence on the normal operation of equipment, so also prolonged greatly the service life of equipment for any one.

Heat pipe 8 connects water tank 9 and smoke boxes 10 in this specific embodiment, and heat pipe 8 and base plate 3 are fixed by electric welding, and boiler smoke enters smoke box by gas approach 1 and washes away heat pipe 8, discharges by exhanst gas outlet 2 again; Water then enters water tank 9 by water pump from water inlet 4, discharges from delivery port 13 again after heating by heat pipe 8, thus the moisturizing temperature of raising boiler.Evacuation port 14 plays the effect that communicates with atmosphere, the safe operation of protection equipment, and shoot door 11 and ash dropping hopper 12 play equipment deashing function.Thermometer 15 can detect coolant-temperature gage, and sewage draining exit 16 is provided convenience for the equipment blowdown.

This specific embodiment heat exchange efficiency height, little, easy for installation, the easy-to-clean ash long service life of resistance.
