Description

Condensing gas heating bath dual-purpose furnace

technical field

The utility model relates to the field of gas furnaces, in particular to a condensing gas heating bath dual-purpose furnace.

Background technique

The wall-hung stove on the existing market is a kind of wall-mounted heating stove. This kind of wall-hung boiler is heated by gas, mainly by premixing gas and air, igniting and burning, and then heating domestic hot water through a simple heat exchange system. Finally, the air is heated through the cooling end, which is a simple process for heating or heating.

This kind of wall-hung boiler has low heat conversion during working heating, short service life, and cannot well achieve a desired heat exchange effect.

Utility model content

In order to solve the above technical problems, the utility model provides a condensing gas heating bath dual-purpose furnace.

The condensing gas heating bath dual-purpose furnace is characterized in that it includes a shell and a controller arranged in the shell, a condenser, a main exchanger, a plate exchanger, a combustion assembly, a circulation pump, a natural gas intake pipe, and an air intake pipe , smoke exhaust pipe, fan, bathroom inlet pipe, bathroom outlet pipe, heating outlet pipe, heating return pipe;

The controller is used to control the operation of the entire furnace body; the condenser is used to perform two different heat exchanges on the water source. During the process, it can continuously absorb heat and heat energy to achieve the effect of condensation; Exchange from top to bottom and continue heating to achieve the effect of heat exchange; there are bathroom inlet pipes, bathroom outlet pipes, heating outlet pipes, and heating return pipes on the plate exchanger. Switch to the bathroom; the combustion assembly is equipped with a natural gas intake pipe, an air intake pipe, a fan, and a fire row; one end of the natural gas intake pipe is used to feed gas, and the other end is connected to the fan in the combustion assembly; the condenser A smoke exhaust pipe is arranged on the top, and the other end of the smoke exhaust pipe passes through the shell and communicates with the outside of the shell.

Further, a safety valve is connected to the plate changer.

The beneficial effects of the utility model are: the result is simple and the operation is convenient;

Because the heating return water first passes through the burner assembly, it effectively reduces the temperature of the burner assembly, reduces the residual flue gas, and reduces the heat loss of exhaust smoke, thereby greatly reducing the generation of nitrogen oxides during the combustion process and achieving the effect of environmental protection. The heating return water is preheated by the secondary condensing heat exchanger, which further reduces the exhaust gas temperature and improves the heat exchange efficiency. During the long-term heat exchange process, there will be no scale in the furnace.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in combination with illustrations and specific embodiments.

As shown in Figures 1 and 2, the condensing gas heating bath dual-purpose furnace includes a shell and a controller installed in the shell, a condenser 2, a main exchanger 3, a plate exchanger 4, a combustion assembly 5, and a circulation pump 6. Natural gas inlet pipe 7, air inlet pipe, smoke exhaust pipe, fan, bathroom water inlet pipe 8, bathroom outlet pipe 9, heating outlet pipe 10, heating return water pipe 11.

The controller is used to control the operation of the entire furnace body; the condenser mainly performs two different heat exchanges on the water source. During the process, it can continuously absorb heat and heat energy to achieve the effect of condensation; the main exchanger mainly uses a cold heating The heat exchange method, the water source is exchanged from top to bottom and continuously heated to achieve a heat exchange effect; the plate exchanger is equipped with bathroom water inlet pipes, bathroom outlet pipes, heating water outlet pipes, and heating return water pipes. Its main functions are Through one plate change and two plate changes, one of the two plate changes is to boil water, and the other is to exchange water to transfer water to the bathroom. There is a safety valve connected to the plate changer. The safety valve is the necessary equipment to ensure the normal operation of the boiler. When the boiler pressure exceeds a certain range of working pressure, it is necessary to open the safety valve drain port at the bottom of the shell to release the steam pressure in the boiler to prevent the boiler from Overpressure explosion.

One end of the natural gas inlet pipe is used to feed gas, and the other end is connected with the fan in the combustion assembly.

One end of the smoke exhaust pipe is connected to the condenser, and the other end passes through the casing and communicates with the outside of the casing.

The working principle of the utility model is as follows: after the controller is powered on, the whole heater controls the operation of the whole furnace body and protects the furnace body through the controller. Natural gas enters the furnace body through the fire row in the combustion assembly to be heated to generate heat. During the combustion process, the exhaust gas generated by the furnace body is transferred to the condenser by the fan through the fire row for secondary heat exchange and recovery, and finally exits the furnace through the smoke exhaust port. body. The water source enters the water pipe in the combustion assembly from the heating return water through the circulation pump, and then enters the condenser, and then from the condenser to the main exchanger. The water outlet of the main exchanger enters the circulation pump through the circulation pipeline. releases heat to the outside world. The other water outlet of the main exchanger is directly transferred to the plate exchanger, and finally flows out through the heating outlet pipe. The water entering the bathroom first passes through the plate changer, and then flows out through the outlet pipe of the bathroom.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. The utility model does not depart from the spirit and scope of the utility model There will also be various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model.
