Abstract

A heating stove comprises a main body and a chimney, wherein a water tank is sleeved at the periphery of the chimney; the space between the inner wall of the water tank and the outer wall of the chimney is partitioned and sealed into a plurality of small heat exchange tanks through diaphragms; the small heat exchange tanks are respectively communicated with a cold water inlet pipe and a hot water outlet pipe at the same time; water pipes are sequentially distributed in the chimney; and two outer ends of the water pipes are parallel and level to the outer wall of the chimney and are fixedly connected and sealed with the chimney. In the utility model, a plurality of mutually independent small heat exchangers are arranged on the chimney, and the water pipes which are communicated with the small heat exchangers are distributed in the chimney, the heat exchange area of the heating stove with the hot waste gas is increased, the cold water or the heating return water can simultaneously enter the mutually independent small heat exchangers, the functions of step-by-step heat exchange can be realized when the hot waste gas penetrates through the chimney from bottom to top, the temperature of the discharged waste gas is far lower than that of a water supply pipe, the thermal pollution to the environment is reduced, the heat supply efficiency is improved, and the coal is saved.

Description

A kind of heating stove

Technical field

The utility model relates to a kind of heat-exchanger rig, relates in particular to the heating stove that a kind of family expenses and small-sized public place use.

Background technology

At present, the used heating stove in domestic heating stove or small-sized public place all is equipped with chimney, is used to get rid of the hot waste gas that burning produces.But any auxiliary equipment is not installed on the chimney of most of heating stove, even small part is equipped with auxiliary equipment, do not reach the purpose that makes full use of used heat yet, the heat in the chimney is discharged with burnt gas, not only cause energy waste, and the hot waste gas of discharging causes thermal pollution to environment.

The utility model content

The purpose of this utility model is to provide a kind of heat that can make full use of heating hot gas, and make the EGT of final discharge lower and the least possible environment is caused the heating stove of thermal pollution.

The technical solution of the utility model is: a kind of heating stove, comprise main body stove, chimney, and described chimney periphery suit water tank, the lower end of this chimney and water tank is simultaneously affixed with the shell lower end of main body stove, and the flue of chimney lower end and main body stove lower end connects; The chimney upper end passes the upper surface of water tank; The two sides of described water tank are connected cold water inlet respectively and are provided with hot water outlet with the upper surface of hot water outlet pipe and this water tank and are connected heating plant; Space between described tank inner wall and the chimney outer wall becomes several little heat exchange box by the dividing plate parting seal, and this little heat exchange box is communicated with the hot water outlet pipe with cold water inlet respectively simultaneously.

As optimization, be arranged in order water pipe in the described chimney, two outer ends of water pipe flush with the chimney outer wall and with the affixed sealing of chimney.

The existing heating stove that auxiliary equipment is housed on chimney, a heat exchanger only is housed, when hot waste gas passes chimney from bottom to top, the heat of hot waste gas is mainly absorbed by heat exchanger in the chimney bottom, and heated hot water can up move in the heat exchanger, thus when hot waste gas continues up to move and the heat exchange action of heat exchanger reduce greatly, both a large amount of high temperature even the hot waste gas that is higher than the feed pipe temperature enter in the atmosphere with chimney, cause atmospheric heat to pollute and waste energy again; The utility model has overcome this shortcoming just, and a plurality of separate little heat exchangers are set on chimney, and the water pipe that discharging is communicated with little heat exchanger in chimney, strengthens the heat exchange area with heating hot gas; A plurality of separate little heat exchangers can advance cold water or heating water return simultaneously, when heating hot gas passes chimney from bottom to top, can realize the function of heat exchange step by step, and make the EGT that finally is discharged temperature well below feed pipe, reduction is to the thermal pollution of environment, and improved heat supply usefulness, save coal-fired.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

A kind of heating stove comprises main body stove 1, chimney 6, described chimney 6 periphery suit water tanks 5, and the lower end of this chimney 6 and water tank 5 is simultaneously affixed with the shell lower end of main body stove 1, and the flue of chimney 6 lower ends and main body stove 1 lower end connects; Chimney 6 upper ends pass the upper surface of water tank 5; The two sides of described water tank 5 are connected cold water inlet 9 respectively and are provided with hot water outlet 4 with the upper surface of hot water outlet pipe 8 and this water tank 5 and are connected heating plant; Space between described water tank 5 inwalls and chimney 6 outer walls becomes several little heat exchange box 3 by dividing plate 2 parting seals, and this little heat exchange box 3 is communicated with hot water outlet pipe 8 with cold water inlet 9 respectively simultaneously; The quantity of little heat exchange box 3 is decided according to the size of heating stove, can establish two to more.

Be arranged in order water pipe 7 in the described chimney 6, two outer ends of water pipe 7 flush with chimney 6 outer walls and with chimney 6 welded seals; Main body stove 1 can be selected family expenses or relatively large common heating power hot stove altogether for use.

Heat exchange pipe is not established in burner hearth of the present utility model the inside, and purpose is under the state that does not influence burner hearth high temperature coal fully to be burnt, and thermal-flame reaches energy-efficient effect through chimney and the calandria heat exchanger heat exchange step by step on it then.
