Abstract

The utility model provides a wood-coal heater which comprises a shell, a combustion chamber and a gas flue and is characterized in that the whole wood-coal heater is a storage water tank except the combustion chamber; smoke absorbing pipes and spiral smoke pipes are fully contacted with the water; the lower part of the wood-coal heater is the combustion chamber; the upper part of the combustion chamber is connected with a plurality of smoke absorbing pipes and spiral smoke pipes; the other ends of the plurality of smoke absorbing pipes are connected with the spiral smoke pipes which are connected with the gas flue; a water inlet pipe is positioned in the gas flue and passes through the gas flue for supplying water for the storage water tank; the combustion chamber comprises a fuel inlet, a fuel inlet cover and an ash hole; and the upper part of the shell is installed with a safety valve and the lower part thereof is installed with a discharging pipe. The wood-coal heater overcomes the defect that the wood heater can not better use the waste heat of the gas fuel; the wood-coal heater can better absorb the waste heat of the gas flue and improve the thermal efficiency; and as the fuel has low cost and is abundant, such as wood, firewood, grass, straw, sewage gas and honeycomb briquette furnaces, the wood-coal heater has broad application value especially in rural areas.

Description

The firewood/coal water heating device

Technical field

The utility model relates to water heater, particularly a kind of firewood/coal water heating device.

Background technology

Along with the continuous progress of science and technology, the kind of water heater also increases day by day, electric energy, solar water heater have occurred, though the EWH is convenient, but waste energy, also bring economically pressure, though solar water heater is energy-conservation to the consumer, but there is the cost height, troublesome maintenance, and the energy is also limited, therefore, for wood, bavin, standing grain, the abundant rural area of bar, it is necessary that a kind of firewood/coal water heating device is provided.

On September 9 2009 day for announcing, the utility model patent of notification number CN201306831Y discloses a kind of firewood-burning water heater, comprises shell and inner bag, and the truncated cone-shaped inner bag that runs through shell body is arranged in the shell; The bottom is the combustion chamber in the inner bag, and top is ventilating opening; Water storage between inner bag and shell has water inlet pipe and water outlet pipe on the shell, the thermal conductive water pipe who connects with shell inner cavity is arranged on the truncated cone-shaped inner bag.This patent has solved heater in the prior art and has used in the rural market and to bring cost height, inconvenient maintenance, defective that fuel is expensive, but the general water quality in rural area is bad, this water heater is the easy scaling of thermal conductive water pipe in use, adds the waste heat that does not utilize flue, so the thermal efficiency is not high.

The utility model content

At the deficiency of above-mentioned similar technology, the purpose of this utility model provides the firewood/coal water heating device that a kind of cost is low, the thermal efficiency is high.

The technical solution of the utility model is: comprise shell, the combustion chamber, flue, it is characterized in that: whole firewood/coal water heating device is storage tank entirely except that the combustion chamber, Smoking pipe, the spiral smoke pipe all fully contacts with water, firewood/coal water heating device bottom is the combustion chamber, top, combustion chamber and some Smoking pipes, the spiral smoke pipe links to each other, the other end of some Smoking pipes links to each other with the spiral smoke pipe, the spiral smoke pipe links to each other with flue, water inlet pipe is positioned at flue, and pass to the storage tank water storage from flue, the combustion chamber comprises fuel inlet, fuel inlet lid and ash hole, shell upper is equipped with safety valve, and the bottom is equipped with outlet pipe.

Thermometer and Pressure gauge near flue also can be housed, at the temperature and pressure that shows storage tank directly perceived on the described shell.

The material of described water heater can be aluminium, copper or stainless steel.

Described shell be shaped as cylinder.

Optimal technical scheme of the present utility model: pressure-reducing valve is housed, on water inlet pipe in order to avoid the hydraulic pressure of water inlet pipe is too high.

Advantage of the present utility model: at first, water inlet pipe of the present utility model is not directly on shell, but runs through flue, wear out to the storage tank water storage from flue, when water inlet pipe penetrates like this, just absorb the waste heat of flue well in flue, improved thermal efficiency.Secondly, the cigarette in the combustion chamber is when many Smoking pipes and spiral smoke pipe, because Smoking pipe fully contacts with the interior water of spiral smoke pipe and storage tank, the overwhelming majority can be absorbed by water, and heat is imitated high.Add that Smoking pipe and spiral flue tube are interior anhydrous, do not produce incrustation scale, durable in use.The adoptable fuel cost of the utility model is low and abundant, as wood, bavin, standing grain, bar, biogas and honeycomb briquette stove, therefore especially in the rural area, is with a wide range of applications.

Description of drawings

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

The specific embodiment

Now in conjunction with the accompanying drawings, technology contents of the present utility model is described further.

Embodiment

The bottom of firewood/coal water heating device is combustion chamber 2, the outside is surrounded by cylindrical shell 1,2 tops, combustion chamber link to each other with spiral smoke pipe 6, some Smoking pipes 5, the other end of some Smoking pipes 5 links to each other with spiral smoke pipe 6, spiral smoke pipe 6 links to each other with flue 3, and the cigarette part of 2 li of combustion chambers is brought spiral smoke pipe 6 into by many Smoking pipes 5 like this, and another part directly enters spiral smoke pipe 6, import flue 3 at last again, pass from cylindrical shell 1.Water inlet pipe 7 is positioned at flue 3, and passes to storage tank 4 water storages from flue 3, on water inlet pipe 7 pressure-reducing valve is housed, in order to avoid the hydraulic pressure of water inlet pipe 7 is too high.Combustion chamber 2 comprises fuel inlet 8, fuel inlet lid 9 and ash hole 10, safety valve 12 is equipped with on cylindrical shell 1 top, thermometer 13 and Pressure gauge 14, and thermometer 13 is near flue 3, the effect of safety valve 12 is: water heater is in heating process, and water is met thermal expansion, and pressure increases, the safety valve 12 (setting 0.4mpa or lower) that pressure is washed open on the water heater makes the water more than part flow out through safety valve 12, make water heater keep setting pressure, both guaranteed safety, can satisfy the requirement that takes a shower again.The effect of thermometer 13 and Pressure gauge 14 is: the temperature and pressure of being convenient to intuitively show storage tank.Shell 1 bottom is equipped with outlet pipe 11.The material of cylindrical shell 1 adopts aluminium, copper, stainless steel material.

The hydromining of water inlet pipe 7 of the present utility model comprises running water with the water that pressure is arranged, and rural area mountain spring water and oneself have the water tower of drop or the water in the bucket, help the heating of water like this, have further improved thermal efficiency.

The utility model has two kinds of mode of heatings: a kind of is to open fuel inlet lid 9, puts into wood, bavin, standing grain, bar, biogas in fuel inlet 8, ignition combustion, thus the water of storage tank 4 is heated.Another kind is closed fuel inlet 8, directly the honeycomb briquette boiler clothing is lived ash hole 10, realizes the heating to water.
