Description

Technical Field

[0001] The invention relates to the technical field of heat exchange, and in particular to a bellows economizer suitable for a smoking furnace. Background Art

[0002] Smoking furnace is a machine suitable for smoking, steaming, drying, grilling and other processing of meat products such as livestock, poultry, fish and other foods. Domestic smoking furnace equipment usually directly discharges the waste gas generated by processing and production, and rarely considers the heat recovery of the waste gas. Since the waste gas generated by the smoking furnace is a high-temperature flue gas containing impurities such as solid particles, grease, and moisture, general energy savers are not suitable for smoking furnaces. Long-term use is prone to blockage, and it is inconvenient to disassemble and clean, which affects the exhaust volume. The waste gas generated by the smoking furnace contains a large amount of heat energy and impurities. Direct emission will cause energy waste and thermal pollution, reduce resource utilization, and aggravate environmental damage.

[0003] The Chinese patent number is: 201520316025.2, which discloses a low-temperature waste heat economizer with a rare earth anti-corrosion coating, which has a cavity for absorbing flue gas from boilers, kilns, etc.; a flue gas inlet is provided on one side of the cavity, and a flue gas outlet is provided on the other side thereof, and a plurality of metal heat exchange tubes are arranged in the cavity, and a condensate discharge device is provided at the bottom of the cavity, and the surface of the metal heat exchange tube is coated with a rare earth anti-corrosion coating. The economizer can not only meet the needs of processing liquid or heating gas, but also effectively reduce the exhaust temperature of boilers and kilns. Since the surface is coated with a rare earth anti-corrosion coating, corrosion is avoided, so that the working efficiency of boilers and kilns is significantly improved, and the emission of pollutants is also reduced, which is more environmentally friendly and energy-saving.

[0004] The Chinese patent number: 201420369534.7 discloses a biomass boiler waste heat flue gas treatment system, which is composed of a biomass boiler, an economizer, a cyclone separator, a bag dust collector and an induced draft fan. The bag dust collector and the induced draft fan are connected with a flue gas waste heat economizer, which includes a cylinder, a heat exchange tube arranged in the cylinder, and a warm water inlet and a heating water outlet arranged on the outer wall of the cylinder. The flue gas waste heat economizer in the system heats the waste heat into water and supplies it to the boiler or other equipment for recycling, thereby reducing the exhaust temperature and reducing energy waste.

[0005] However, such energy savers are not very suitable for smokehouses. They are prone to blockage after long-term use and are inconvenient to disassemble and clean, which affects the exhaust volume. The bellows energy saver suitable for smokehouses of the present invention can effectively avoid these problems. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides a bellows economizer with a reasonable structural design suitable for a smoking furnace.

[0016] Figure 2 It is a schematic diagram of the guide plate structure of the present invention;

[0017] In the figure: 1-box, 2-bellows, 3-front baffle, 4-rear baffle, 5-guide plate, 6-front cover, 7-rear cover, 8-sealing gasket, 9-fresh air inlet, 10-fresh air outlet, 11-exhaust gas outlet, 12-exhaust gas inlet. DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-2 As shown, the present invention is a bellows economizer suitable for a smoker, comprising a box body 1, a bellows 2, a front baffle 3, a rear baffle 4, a guide plate 5, a front cover 6, a rear cover 7, a sealing gasket 8, a fresh air inlet 9, a fresh air outlet 10, an exhaust gas outlet 11 and an exhaust gas inlet 12.

[0020] The bellows energy saver suitable for the smoke furnace is mainly composed of 1 box body, 16 bellows, 1 front baffle, 1 rear baffle, 1 guide plate, 1 front cover, 1 rear cover, 2 sealing gaskets and 1 fresh air inlet, 1 fresh air outlet, 1 exhaust gas inlet and 1 exhaust gas outlet.

[0021] The bellows economizer of the present invention is installed at the exhaust gas outlet of the smoker to play the role of energy saving and emission reduction; the front cover, front baffle, rear cover and rear baffle are respectively installed at the front and rear ends of the box; the exhaust gas outlet and the exhaust gas inlet are respectively welded to the top and bottom of the box; the front cover and the rear cover are respectively welded with the fresh air inlet and the fresh air outlet. In the present invention, there are 16 bellows arranged in an equidistant square, and the two ends are respectively connected to the front baffle and the rear baffle, forming a component with the front baffle and the rear baffle, installed in the box, and connected to the front cover and the rear cover. In the present invention, the guide plate 5 is installed in the middle position of the front baffle, facing the fresh air inlet, and the guide plate 5 includes a spherical base 501 and four round tubes 502, and the four round tubes 502 are aligned with the four middle bellows in the box. In the present invention, there are two sealing gaskets, which are respectively installed between the front cover and the box, and the rear cover and the box for sealing.

[0022] The bellows economizer suitable for a smokehouse of the present invention mainly realizes waste heat recovery through heat exchange of cold and hot fluids, specifically, the heat of the exhaust gas discharged from the smokehouse is transferred to the fresh air entering the smokehouse. In order to prevent the fresh air from being polluted by the exhaust gas, the cold and hot fluids must flow in two independent flow channels, and sufficient heat exchange is required to improve the recovery efficiency, while not affecting the exhaust of the smokehouse. The exhaust gas flow duct is composed of an exhaust gas inlet, a box body, a front baffle, a rear baffle, the outer wall surfaces of 16 corrugated pipes and an exhaust gas outlet. The exhaust gas discharged from the smoker enters the bellows energy saver from the exhaust gas inlet, flows through the exhaust gas flow duct, heats the outer walls of the 16 corrugated pipes, and then converges at the exhaust gas outlet to flow out of the bellows energy saver; the fresh air flow duct is composed of a fresh air inlet, a front cover, a front baffle, the inner walls of 16 bellows, a rear baffle, a rear cover and a fresh air outlet. The fresh air entering the smoker enters the bellows energy saver from the fresh air inlet, flows through the fresh air flow duct, absorbs heat from the inner wall of the bellows, and then converges at the fresh air outlet to flow out of the bellows energy saver and enter the smoker. Specifically, after the fresh air enters the bellows economizer from the fresh air inlet, part of the airflow directly passes through the four round tubes welded on the guide plate and enters the four middle bellows for heat exchange. The other part hits the airflow center of the guide plate (i.e. the top center of the spherical base) and then disperses to the twelve bellows around the sphere for heat exchange. The advantage of this is that the fresh air flows through the 16 bellows relatively evenly, making the heat exchange more sufficient and improving the recovery efficiency. A bellows economizer suitable for a smoke furnace is small in size, light in weight, easy to disassemble and clean, has high heat recovery efficiency, and does not affect the exhaust volume of the smoke furnace. The bellows itself has the advantages of strong ability to compensate for thermal stress and strong anti-scaling ability.

[0023] It is understandable that those skilled in the art can make equivalent substitutions and changes based on the technical solution and inventive concept of the present invention, and all these changes and substitutions should fall within the protection scope of the present invention.
