Abstract

The utility model relates to an internal circulation type efficient energy-saving furnace which is the combination body of a household coal furnace and a water heater. The utility model is characterized in that an internal circulation type heater is sheathed horizontally on the upper part of the furnace core of a coal furnace, and the internal circulation type heater is composed of an annular hollow metal pipe whose cross section is rectangular and a water inlet pipe and a water outlet pipe arranged on the two ends of the annular hollow metal pipe. The water inlet pipe and the water outlet pipe are totally extended into the same water tank, and the position of a water inlet in the water tank is lower than a water outlet. When the internal circulation type heater is heated by the furnace core, hot water in the internal circulation type heater is flown into the upper part of the water tank from the water outlet. Cooler water of the lower part of the water tank is sucked by the water inlet pipe into the internal circulation type heater to be heated. The process is repeated again and again in such a manner, internal circulation is never stopped, and the water temperature of the water in the integral water tank is gradually risen for people' s living requirements.

Description

The internal-circulation type efficient energy-saving furnace

The utility model relates to a kind of cooking, hot-water heating commercial coal stove, is a kind of novel internal-circulation type efficient energy-saving furnace.

Developed multiple Civil energy-saving cooking stove and water heater at present, have with the heating of coal or firewood, have with coal gas or electrical heating, all need consume a large amount of energy.Utilize the heater of waste heat also constantly to come out in recent years, but great majority adopt direct conduction-type, so the thermal efficiency is lower, can not satisfy the needs of people's lives.

The purpose of this utility model provides a kind of energy of can saving can make full use of the commercial coal stove of waste heat and the combination of hot-water heating system again.

The purpose of this utility model is achieved in that on the top, outside of coal stove fire box 2 and is with an internal-circulation type water heater that this heater is that the hollow metal pipe 3 of rectangle and water inlet pipe 4 and the outlet pipe 5 that is communicated with it constitute by a ring-type, the horizontal face of planting.Water inlet pipe 4 and outlet pipe 5 put in the same water tank 6.The position of water inlet pipe mouth in water tank 6 is lower than effluent pipe mouth.Coal stove assembly 1 is installed in and gives in the water tank 6 in the tube of leaving a blank, and this sky tube is wrapped up by the water of water tank.After the ring-shaped sleeve of heater is heated, water in the pipe will produce automatic circulation, hot water is injected water tank upper continuously, and the colder water in water tank bottom constantly is sucked into heating in the ring-shaped sleeve, so go round and begin again, water temperature in the whole water tank also just constantly raises, reach the temperature that needs after, live required for people.

The utility model is because only need be at internal-circulation type ring-shaped heater of flue outside cover, so structure is simple especially; Water circulation does not simultaneously need additionaling power, therefore uses easily; The water tank heat preserving performance is good, and the hot water of storage is available at any time, can satisfy people and live and need use.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Below in conjunction with details and the working condition thereof of accompanying drawing detailed description according to the energy-conservation stove that the utility model proposes.

According to shown in Figure 1, this internal-circulation type efficient energy-saving furnace, comprise a coal stove assembly 1, an internal-circulation type heater arranged in coal stove fire box 2 outsides, this heater by one overlook for ring-type, the horizontal face of planting be that the hollow metal pipe 3 of rectangle and the water inlet pipe and the outlet pipe 5 that are communicated with it constitute.Water inlet pipe 4 and outlet pipe 5 all put in the same water tank 6, and the position of water inlet pipe mouth in water tank 6 is lower than effluent pipe mouth.Between flue 2 and the furnace shell 7, and between water tank 6 and the outer bag box 8, all fill full good especially perlite or the asbestos wool of heat-insulating property, filled with water 10 in the water tank 6.After the loop pipe 3 of heater is heated by flue 2, water in the loop pipe 3 also are heated, and hot water flows to the top of water tank 6, the water that the water tank bottom is colder from effluent pipe mouth, heat in the water inlet pipe mouth inspiration heater loop pipe 3 of heater, heating back hot water flows to water tank 6 again.So go round and begin again, day and night circulate and do not stop, the water in the water tank 6 constantly is heated, and the water temperature of whole water tank raises gradually, can reach more than 90 ℃.Coal stove assembly 1 is installed in the tube of leaving a blank in advance of water tank 6, and this sky tube is wrapped up by the water of water tank, and coal stove assembly 1 also can be arranged on water tank 6 outside next doors separately.Coal stove is for cooking a meal usefulness, and hot water can supply bath in a tub, shower and other living needs.The pondage of water tank 6 is generally 150-200kg, this coal stove and inequal substantially with cook a meal the separately coal consumption of coal stove of usefulness of water tank.Water tank and heater can not reduce furnace temperature influences firepower.

In the drawings, the 11st, the running water inlet of water tank 6, the 12nd, the hot water outlet of water tank, the hot water in the water tank 6 so impulse force is very big when putting hot water, can supply the usefulness of spray because of being subjected to the pressure of running water.

Claims (2)

1, a kind of internal-circulation type efficient energy-saving furnace, it comprises coal stove assembly (1) and water tank and heater, it is characterized in that being with an internal-circulation type water heater on the top, outside of coal stove fire box (2), this heater is by a ring-type, the horizontal face of planting is the hollow metal pipe (3) of rectangle and water inlet pipe (4) that is communicated with it and outlet pipe (5) formation, water inlet pipe (4) and outlet pipe (5) put in the same water tank (6), the position of water inlet pipe mouth in water tank (6) is lower than effluent pipe mouth, coal stove assembly (1) is installed in the water tank (6) and gives in the tube of leaving a blank, and this sky tube is wrapped up by the water of water tank.
