Description

Tube and tube tail heat utilization multifunctional biomass energy stove

technical field

The utility model relates to a multi-functional biomass energy cooker for utilization of tubular tail heat.

Background technique

Biomass mainly refers to lignin or cellulose such as straw and trees other than grain and fruit in the agricultural and forestry production process. Biomass energy is directly or indirectly derived from the photosynthesis of green plants. It is a renewable energy source and the only renewable carbon source.

Since biomass energy is a renewable resource, it is one of the new energy sources vigorously advocated by the country. The wood-fired stoves used in rural households can be regarded as the simplest and most primitive biomass energy stoves, but these biomass energy stoves generally have thermal energy utilization. The defects of low efficiency, insufficient combustion, and much smoke are not in line with the energy-saving and emission-reduction policies advocated by the country at this stage. Therefore, it is of great significance to design efficient and clean biomass fuel burning stoves.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a multifunctional biomass energy stove capable of indoor combustion, high thermal efficiency, quickness, and full use of tail heat, which has multiple functions such as heating, cooking, and hot water. This function is suitable for farm restaurant-style catering hot pot and buffet. At the same time, it can realize heating at the end of winter, and it is also especially suitable for cooking and heating in Chinese rural families in winter.

In order to overcome the deficiencies in the prior art, the utility model adopts the following technical solutions:

A shell and tube tail heat utilization multifunctional biomass energy stove, including a combustion chamber surrounded by refractory mud and a furnace bridge, a gray chamber is arranged under the furnace bridge, and the feature is that a detachable inner cover is arranged above the combustion chamber; The ash chamber is provided with an air intake pipe to communicate with the outside world. The air intake pipe is provided with a damper for adjusting the air volume. The combustion chamber is provided with an exhaust port connected to the tube side of the shell and tube heat exchanger and then emptied from the outlet pipe; the shell of the shell and tube heat exchanger There is a water control valve and an overflow pipe in the process; the outer cylinder is surrounded by refractory mud, and a protective cover is installed around the outer cylinder, and a frying pan or a large cover is erected above the outer cylinder to isolate the smoke and prevent overflow.

A stove foot is provided at the bottom of the refractory mud.

A movable table is arranged above the outer cylinder, and dishes can be kept warm by placing dishes on the table.

The refractory mud in the outer cylinder and the furnace bridge form a combustion chamber. The biomass-made machine-made charcoal is placed on the furnace bridge for combustion. The damper can control the air intake of the intake pipe to control the firepower and combustion. The furnace bridge can be removed to clean the ash chamber. , the protective cover can avoid accidental contact and cause burns, the inner cover is used to press the fire, and the large cover is used to isolate the exhaust gas from overflowing when roasting; the natural thermal power is used to achieve exhaustion, and the exhaust pipe enters the tube-and-tube heat exchanger for exhaust. Heat recovery produces hot water for cooking, and heat is emitted through the furnace wall to heat the room and the tabletop, making it easy to keep the dishes on the table warm. Open the large cover and inner cover and put it on the frying pan to carry out catering processing.

The tube-and-tube heat exchanger is composed of a cylinder and uniformly distributed tubes inside. The exhaust gas goes through the tube side, and the shell side stores water to absorb the heat of the exhaust gas. Water as a carrier can efficiently absorb the tail heat and generate hot water for washing vegetables, cooking and washing face. Wait, open the water control valve and enter the cold water to overflow the hot water from the overflow pipe for use, and the outer wall of the cylinder is convenient to export the excess internal heat to the room to increase the indoor temperature, and finally the low-temperature exhaust gas is discharged to the outside through the exhaust outlet pipe.

Compared with the prior art, the utility model has the beneficial effects of:

The flue gas is completely exhausted outside, and the tube-type tail heat recovery is simple and efficient. It not only generates hot water but also warms the room, realizing energy saving, emission reduction and high-efficiency utilization. The new type has multiple functions, not only for heating, but also for hot pot and cooking and generating hot water for use, and the firepower is easy to adjust. It is especially suitable for farm restaurant type catering hot pot and buffet. Food, heating, biomass energy resources are abundant, and the application prospect is broad.
