The cooking stove heat recovery ring-shaped case with the holes is characterized in that a plurality of corresponding ventilating holes are arranged on the inner and outer side walls of the ring-shaped case; connection pipes are put across in the case, one end of the connection pipes is welded on the ventilating holes on the inner wall, and the other end is welded on the ventilating holes on the outer wall; an enclosed ring-shaped case with the holes is formed. The utility model has a simple structure; the heat emitted to ambient space when a stove and an accessory and a kitchen range are heated is utilized to heat the water in the enclosed ring-shaped case with the holes, the hot water can be directly used and can also be accessed a heat preservation barrel to store through a water pipe, the waste of the heat energy can be effectively reduced, the utilization rate of the energy resource can be raised, and the cooking stove heat recovery ring-shaped case with the holes can be widely applied to gas kitchen ranges.

Description

Utilizing afterheat of kitchen range reclaims ring box with holes

Technical field

The utility model relates to a kind of coal gas waste-heat recovery device, exactly is that a kind of utilizing afterheat of kitchen range reclaims ring box with holes.

Background technology

At present, the gas range that uses in family and restaurant is open heating, the heating in have sizable a part of heat to around the space distribute, cause the waste of heat energy, in order to utilize the waste heat of combustion flame, people develop the coal gas residual heat using device, for example, the ring water pipe that people use always carries out waste heat and adds hot water, and this ring water pipe thermal efficiency is lower, is difficult for applying.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, with low cost, and thermal-arrest is even, and heat absorption is abundant, and the utilizing afterheat of kitchen range that heat recovery rate is high reclaims ring box with holes.

According to the utility model, described utilizing afterheat of kitchen range reclaims ring box with holes, comprise a ring box, the ring box lateral wall is provided with water inlet pipe and outlet pipe, it is characterized in that having several corresponding air vents on the inside and outside sidewall of ring box, tube connector is disposed across in the box, and an end is connected with the inwall air vent, the other end is connected with the air vent of outer wall, constitutes the ring box with holes of a sealing.Described ring box inside upper part with holes is established a retaining flame sheet.

Reclaim ring box with holes according to utilizing afterheat of kitchen range described in the utility model, described ring box can be made square, round, square or triangular form.

The utility model utilizing afterheat of kitchen range reclaims ring box with holes and the supporting use of existing gas stove, this waste heat recovery ring box with holes can fully be collected the waste heat that gas-cooker produces during use, waste heat is absorbed by the cold water in the box by ring box with holes, and the cold water in the box is heated.Because the utility model adopted above-mentioned design concept, have simple in structurely, with low cost, thermal-arrest is even, heat absorption fully, the characteristics that heat recovery rate is high.If hot water is connected with heat-preservation cylinder, can also long time stored hot water, reduce the waste of heat energy effectively, the raising rate of energy, the waste heat recovery rate is up to more than 60～85%.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to accompanying drawing 1,3,4, utilizing afterheat of kitchen range reclaims ring box with holes, comprise a ring box 3, ring box 3 lateral walls are provided with water inlet pipe 6 and outlet pipe 4, it is characterized in that having several corresponding air vents on the inside and outside sidewall of ring box 3, tube connector 2 is disposed across in the box, and an end is welded on the inwall air vent, the other end is welded on the air vent of outer wall, constitutes the ring box with holes of a sealing.In order to make the utility model waste heat recovery better effects if, the utility model is established a retaining flame sheet in described ring box inside upper part with holes, referring to accompanying drawing 2, reduced thermal loss effectively, the air vent of being opened on the ring box sidewall had both increased the heating surface area of waste-heat recoverer, required oxygen when having guaranteed again that coal gas fully burns.

During use, the coal gas stove is put in utilizing afterheat of kitchen range to be reclaimed in the hollow part of ring box with holes, gas pipe inserts the coal gas stove by the gas pipe import of the bottom of confining zone hole ring box, when the gas-fired heating cooker, cold water enters in the ring box of sealing by water inlet pipe, absorb the coal gas stove to around the heat that distributes of space water temperature is raise, hot water flows out by outlet pipe, the hot water that flows out can directly use, make people utilize remaining hot water to wash one's face winter, wash the dishes, the usefulness of having a bath summer also can insert heat-preservation cylinder by water pipe and store, in ring box, required oxygen when the air vent of being opened on the lateral wall also can be supplied gas-fired.

Described ring box described in the utility model can be made square, round, square, triangular form or other geometry as required.

The utility model can be widely used on the various gas cookers, is specially adapted to hotel, restaurant's UTILIZATION OF VESIDUAL HEAT IN, reaches the waste that reduces heat energy, improves the purpose of energy utilization rate.
