Device for treating and recycling exhaust gas of boiler

Abstract

A device for treating and recycling exhaust gas of a boiler comprises a box. A water inlet pipe is arranged in the middle of the left end of the box. A bent air pipe is arranged at the lower portion of the left end in the box. The left end of the bent air pipe is connected with a first suction fan. The left end of the first suction fan is connected with an exhaust gas outlet of the boiler through a pipe. A water tank is arranged at the lower left end in the box. The bent air pipe is arranged in the water tank. The bottom end of the right side of the water tank is connected with a water pump at the upper end of the water tank through the bent water pipe. The water pump is connected with a straight water pipe on the right side. The straight water pipe is connected with four spraying devices. An exhaust pipe is arranged in the middle of the right side face of the box. The right side of the exhaust pipe is connected with a second suction fan. A water outlet pipe is arranged on the right side of the bottom face of the box. The device can effectively remove harmful gas and dust in exhaust gas of the boiler, utilize the waste heat in the exhaust gas of the boiler to heat cold water and then drain the heated water to the boiler to be used, energy saving and environment protecting are achieved, and the exhaust gas is used.

Description

technical field [0001] The invention relates to the technical field of food production equipment, in particular to a boiler waste gas treatment and reuse device for solving the waste gas generated during the operation of food production boilers. Background technique [0002] The existing small and simple boilers used for food boiling processing or heating and disinfection have poor smoke and dust removal effects, which not only lead to poor food quality, but also cause high fuel consumption and long processing time due to the low utilization rate of heat energy, such as: Many small private food processing factories have been using old-fashioned boilers for production. After burning a large amount of fuel, there is a lot of smoke and dust pollution in the air in the factory area. Most of the workshops adopt fully enclosed dust-proof facilities. The air circulation is poor, the air is stuffy, and the air contains bacteria. The amount is also greater than the outdoor air, thus ...

AI Technical Summary

Problems solved by technology

[0002]The existing small and simple boilers used for food boiling or heating and disinfection have poor smoke and dust removal effect, which not only makes the food quality poor, but also has a low utilization rate of heat energy. Low fuel consumption and long processing time. For example, many small private food processing factories have been using old-fashioned boilers for production. After burning a large amount of fuel, the air in the factory area is heavily polluted by smoke and dust, and most of the workshops are fully enclosed. Dust-proof facilities, poor air circulation, hot air, air bacteria content is greater than outdoor air, thus affecting the quality of food processing

As for the boiler equipment that uses long-distance delivery of hot steam to thermally process food, the heating speed is inferior to that of an open flame, which makes the balance of food cooking degree poor and seriously affects the quality of food.

However, due to limited funds or other reasons, some small private food processing factories cannot purchase large or better boilers, so this problem cannot be solved
