Description

Technical Field

[0001] The utility model relates to the field of heating furnace temperature control, in particular to a heating furnace air supply and exhaust cooling system. Background Art

[0002] The beverage industry is a rapidly developing pillar industry in my country, with a huge market size. In 2015, the total sales of China's beverage market was 673.4 billion yuan, with a compound annual growth rate of 12.6% from 2011 to 2015. It is estimated that in 2017, the market size of China's beverage industry will grow to 829 billion. In beverage factories, the bottle embryos need to be heated and softened by a heating furnace, which requires energy generation. However, since the heat generated by the heating furnace is very large and generates heat radiation, in the same factory building, the cooling effect of a single exhaust system is limited, and the heat generated by the heating furnace cannot be effectively balanced. In order to cool down the operators, it is necessary to turn on high-power refrigeration equipment to suppress the heat energy generated by the heating furnace to avoid discomfort to the operators, which is prone to large losses. Based on the above situation, the utility model proposes a heating furnace exhaust cooling system to effectively solve the above problems. Utility Model Content

[0003] In order to solve the problems existing in the background technology, the utility model provides a heating furnace exhaust air cooling system.

[0004] The utility model adopts the following technical solutions:

[0005] A heating furnace air supply and exhaust cooling system includes an air supply and exhaust hood, a heating furnace, a ventilation duct and a fan. The air supply and exhaust hood is a jacket structure connected to the ventilation duct and arranged above the heating furnace. The ventilation duct is an air supply duct and an exhaust duct. A fan is arranged in the duct to connect indoor and outdoor air. The air supply and exhaust hood covers the top of the heating furnace, gathers the upward hot air generated by the heating furnace, and discharges the hot air to the outside through the fan arranged in the exhaust duct; at the same time, the air supply duct supplies air to the room through the fan arranged in the air supply duct to achieve heat exchange. The air supply and exhaust hood is a jacket structure, which makes the air supply duct and the exhaust duct fit closely, saving space.

[0006] Furthermore, the air outlet outside the ventilation duct is higher than the air supply outlet. Since the density of hot air is lower than that of cold air, the air outlet is arranged at a position higher than the air supply outlet to avoid accidental inhalation of the discharged hot air.

[0007] Furthermore, a bracket is provided above the heating furnace, the bracket abuts against the air supply and exhaust hood, and the bracket is a frame structure. Since the air supply and exhaust hood is arranged above the heating furnace, in order to reduce the hanging weight, an additional bracket is provided to bear the weight and reduce the burden of the upper hanging.

[0008] Furthermore, the jacket structure of the air supply and exhaust hood is a nesting doll structure that combines two and / or more relatively independent cavities, and the cavities are respectively connected to the air supply channel and the exhaust channel. The multiple relatively independent cavities of the jacket structure are conducive to the air not being affected by each other during the heat exchange process, making the circulation smoother and improving the exchange efficiency.

[0009] Furthermore, the air supply and exhaust hood is in an inverted funnel shape, with air supply ports on both sides connected to the air supply channel, and an exhaust port connected to the exhaust channel at the center of the air supply and exhaust hood. The air supply ports are arranged on the side, which effectively cools down the area around the heating furnace affected by the radiant heat of the heating furnace, avoiding further diffusion of radiant heat and raising the indoor temperature.

[0010] Furthermore, the air supply port is provided with shutters and a filter. When the air supply fan is turned off, the shutters are closed to close the air supply channel, and a filter is provided in the channel to prevent debris in the outdoor air from being sucked into the room.

[0011] The utility model provides a heating furnace exhaust air cooling system with the beneficial effect that: while the heat generated by the heating furnace is discharged outdoors through the exhaust duct, the fresh air delivered in by the air supply duct can reduce the temperature of the exhaust duct body while being absorbed by the heating furnace and then discharged through the exhaust duct.

[0012] This can reduce the heat radiation generated by the heating furnace and achieve more efficient use of thermal energy, thereby achieving the goal of saving energy and protecting the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Embodiment 1-air supply and exhaust hood; 2-bracket; 3-air supply duct; 4-exhaust duct; 5-air supply fan; 6-exhaust fan; 7-heating furnace; 8-shutter; 9-clean room; 10-air conditioning:

[0019] See attached Figures 1 to 3 As shown:

[0020] A safe and environmentally friendly electric power cabinet device includes an air supply and exhaust hood 1, a heating furnace 7, a ventilation duct and a fan. The air supply and exhaust hood 1 is a jacket structure connected with the ventilation duct and arranged above the heating furnace 7. The ventilation duct is an air supply duct 3 and an exhaust duct 4. A fan is arranged in the duct to connect indoor and outdoor air. The air supply and exhaust hood 1 covers the heating furnace 7 directly above the heating furnace 7, gathers the upward hot air generated by the heating furnace 7, and discharges the hot air into the clean room 9 through the exhaust fan 6 arranged in the exhaust duct 4; at the same time, the air supply duct 3 supplies air to the clean room 9 through the air supply fan 5 arranged in the air supply duct 3 to achieve heat exchange. The air supply and exhaust hood 1 is a jacket structure so that the air supply duct 3 and the exhaust duct 4 fit closely, saving space.

[0021] The exhaust port of the ventilation duct in the clean room 9 is higher than the air supply port. Since the density of hot air is less than that of cold air, the exhaust port is set at a position higher than the air supply port to avoid accidental inhalation of the discharged hot air.

[0022] A bracket 2 is arranged above the heating furnace 7, and the bracket 2 is in contact with the air supply and exhaust hood 1. The bracket 2 is a frame structure. Since the air supply and exhaust hood 1 is arranged above the heating furnace 7, in order to reduce the hanging weight, an additional bracket is arranged to bear the load and reduce the burden of the upper hanging.

[0023] The jacket structure of the air supply and exhaust hood 1 is composed of two and / or more cavities that are relatively independent of each other in a nesting doll structure, and the cavities are respectively connected to the air supply channel 3 and the exhaust channel 4. The multiple relatively independent cavities of the jacket structure are conducive to the air not being affected by each other during the heat exchange process, making the circulation smoother and improving the exchange efficiency.

[0024] The air supply and exhaust hood 1 is in the shape of an inverted funnel, with air supply ports on both sides connected to the air supply channel 3, and an exhaust port in the central area of ​​the air supply and exhaust hood 1 connected to the exhaust channel 4. The air supply ports are arranged on the side, which effectively cools down the area around the heating furnace 7 affected by the radiant heat of the heating furnace, avoids further diffusion of radiant heat, and raises the temperature of the clean room.

[0025] The air supply port is provided with shutters 8 and a filter. When the air supply fan 5 is turned off, the shutters 8 are closed to close the air supply channel, and a filter is provided in the channel to prevent foreign matter in the outdoor air from being sucked into the room.

[0026] The solution proposed by the utility model saves a lot of energy consumed by the air conditioner to process a large amount of fresh air in order to maintain positive pressure with pure exhaust air. For example, the general exhaust volume is above 20,000m3 / h. Taking the exhaust volume of 20,000m3 / h in Hangzhou as an example, in order to maintain the positive pressure (temperature of 26 degrees), only 20,000m3 / h of fresh air is supplemented in summer, which requires 250KW of cooling capacity, equivalent to 50KW of electricity consumption. The heating furnace heats the fresh air to the required temperature (70~80 degrees), which is equivalent to 100KW of electricity consumption, and there is only one heating furnace. After using the new system, the air conditioner no longer needs to process the supplementary fresh air volume equivalent to the exhaust volume, and the fresh air is heated by the internal heat exchange of the jacket, and the temperature is increased, which reduces the energy consumption of the heating furnace to heat the fresh air, saves a lot of energy and the air conditioning box refrigeration copper coil, thereby greatly reducing the initial investment and operating costs, and saving a lot of energy for the country.
