Abstract

The invention discloses a device used for producing boiling water and vapor and capable of reducing the temperature of a smoke exhaust fan effectively. The device provided by the invention comprises a burner, a water tank, a smoke coiled tube, a smoke exhaust fan and an electronic control device, wherein the side face of the water tank is provided with a boiling water tank or a vapor outlet, the outside of the water tank is provided with a water storage tank, and the device is characterized in that flues comprise an upper flue and a lower flue, a coiled tube type water pipe is arranged in the lower flue, the periphery of the upper flue on the top of the water tank is provided with a cooling water tank, and the smoke exhaust fan is fixed on the cooling water tank. Compared with the prior art, the invention has the advantages that the device can reach the endured temperature of a common smoke exhaust fan, and is low in production cost and reliable in operation.

Description

Technical field: [0001] The invention relates to a gas boiling water / steam device. Background technique: [0002] As disclosed in the patent application 200910038430.1 of the applicant for this patent, in order to reduce the temperature of the exhaust fan as much as possible to ensure that the exhaust fan has good durability, this technology adopts a method of reducing the temperature of the exhaust fan to reduce the temperature of the exhaust fan. The technology adopted includes interlayer water tank outside the smoke exhaust pipe and coiled water pipe inside the smoke exhaust pipe. Although this technology reduces the temperature of the smoke exhaust fan to a certain extent, because the metal shell of the smoke exhaust fan The top of the main water tank of the boiling water tank is connected together, and the top of the main water tank of the boiling water tank is the part with the highest water temperature. The interlayer water tank is connected with the back of both side...

[0002] As disclosed in the patent application 200910038430.1 of the applicant for this patent, in order to reduce the temperature of the exhaust fan as much as possible to ensure that the exhaust fan has good durability, this technology adopts a method of reducing the temperature of the exhaust fan to reduce the temperature of the exhaust fan. The technology adopted includes interlayer water tank outside the smoke exhaust pipe and coiled water pipe inside the smoke exhaust pipe. Although this technology reduces the temperature of the smoke exhaust fan to a certain extent, because the metal shell of the smoke exhaust fan The top of the main water tank of the boiling water tank is connected together, and the top of the main water tank of the boiling water tank is the part with the highest water temperature. The interlayer water tank is connected with the back of both sides of the main water tank. The heat radiation area of ​​the main water tank is large and the water temperature is high. , the flow of water is slow, and its contribution to the reduction of the temperature of the flue gas in the exhaust pipe and the temperature of the top of the boiling water tank is not large. Moreover, if steam is produced, in order to ensure the output of steam, it is often necessary to remove the interlayer water tank around the main water tank. Ensure that there is enough heat energy to produce steam, which will inevitably make the temperature of the top of the main water tank very high, and metal is a good heat-conducting material, so that the temperature of the shell of the smoke exhaust fan connected to the top of the main water tank will be very high. In such a high-temperature metal atmosphere, even if the coiled water pipe lowers the temperature of the flue gas as much as possible, the temperature that the exhaust fan is subjected to is very high, so that the temperature of the exhaust fan cannot be lowered to that of a general exhaust fan. In order to ensure reliable operation within the operating temperature range, we can only choose expensive and high-temperature-resistant smoke exhaust fans, which will inevitably greatly increase the manufacturing cost of the product
