This utility model discloses a high-temperature steam waste heat recovery and reuse device for deodorization towers, comprising: a deodorization tower body, an mounting base fixedly installed on the outer wall of the deodorization tower body, a preheating box fixedly installed on the top wall of the mounting base, an oil storage tank fixedly installed inside the preheating box, a steam pipe fixedly installed at the top of the deodorization tower body, a diverter fixedly installed at the end of the steam pipe away from the deodorization tower body, a first spiral heat-conducting pipe fixedly installed on the diverter, and a second spiral heat-conducting pipe fixedly installed on the diverter, the first spiral heat-conducting pipe being sleeved on the outer wall of the oil storage tank, and the second spiral heat-conducting pipe being installed in the inner cavity of the oil storage tank. This utility model realizes the utilization of waste heat from the high-temperature steam of the deodorization tower, preheating the edible oil to be deodorized, thus greatly reducing the heating time required for the edible oil to be deodorized during deodorization processing and improving the efficiency of edible oil deodorization processing.

The application discloses a high-tower granulation industrial waste heat recovery feeding device, and relates to the technical field of heat recovery.The device comprises a preheating bin, a separate sleeve layer, a storage cavity, a slow-flow bin, a material flow channel, a feeding pipe and an adjusting structure.In the application, the material flows into the slow-flow bin through the feeding pipe and then reversely flows out from the channel between the inner wall of the slow-flow bin and the feeding pipe.The sudden reversal of the flow direction not only effectively reduces the material flow rate, but also makes the material strongly mix under the action of turbulent flow, breaks the stagnant dead zone of the traditional container center area, and improves the overall preheating effect, since the slow-flow bin and the variable-speed design slow down the overall flow rate of the material in the annular material flow channel, increase the residence time, and ensure that the heat of the heat-conducting medium can fully penetrate the material layer.

This utility model discloses a copper foil composite heat insulation pressing device, including a base and a fixed frame disposed on the top of the base. Two first guide rollers distributed vertically are rotatably connected to the inner cavity of the fixed frame near the left side. In use, through the linkage of a first servo motor, a first threaded rod, a first threaded sleeve, a sliding rod, a sliding groove, a traction rod, and an arc-shaped limiting plate, the horizontal distance between the two arc-shaped limiting plates can be adjusted according to the width of the copper foil. Thus, when the copper foil passes between the two first guide rollers, it can be corrected and limited, thereby preventing the copper foil from slipping and tilting during the traction process. In addition, through the setting of a first slot, a first arc-shaped plate, a second slot, and a second arc-shaped plate, the copper foil can be corrected during the conveying process. At the same time, the heating efficiency of the heating roller can be effectively improved, thereby improving the pressing effect on the copper foil.

This utility model relates to the field of waste incineration technology, specifically to a heat recovery structure for a pyrolysis gasification furnace. The heat recovery structure for a pyrolysis gasification furnace includes: a pyrolysis gasification furnace; a support frame, the support frame being disposed on one side of the pyrolysis gasification furnace; and an auger conveyor, the auger conveyor being mounted on the support frame, the auger conveyor including a conveying pipe and an auger shaft disposed within the conveying pipe. The beneficial effects of this utility model are: this device covers the outside of the conveying pipe of the auger conveyor with a heating hood, and connects the exhaust port of the pyrolysis gasification furnace to the sealed chamber between the heating hood and the conveying pipe through an inlet pipe, allowing high-temperature flue gas to directly fill the sealed chamber, and then heat the conveying pipe through heat conduction, thereby achieving preheating treatment of the waste in the conveying pipe. This not only effectively recovers the heat energy in the flue gas and reduces heat loss, but also ensures that the waste reaches a higher temperature and a drier state before entering the pyrolysis gasification furnace.

This utility model relates to the field of shipbuilding technology, and in particular to a heating device for welding and installing shipboard passageway pipe fittings. It includes a first fixing plate, on which two second fixing plates are symmetrically fixed. Electric heating tubes are fixed to the opposite sides of each of the two second fixing plates. A fixing column is fixed to the first fixing plate, which is positioned between the fixing column and the two second fixing plates. A reciprocating reverse drive mechanism is fixed to the end of the fixing column furthest from the first fixing plate. In use, the two reciprocating electric heating tubes simultaneously preheat the inner and outer walls of the passageway pipe fitting, ensuring that the preheating of the inner and outer walls is not sequential, thereby improving the uniformity of preheating and ultimately enhancing the preheating effect.

The utility model accurate control micro - electric telescopic handle, drive the spray head adjustment height, ensure that every spray head and the distance of the surface of the circuit board to be processed are consistent. Effectively solved the problem of uneven spraying caused by the uneven surface of the circuit board, improved the spraying quality and precision.

This utility model relates to the field of boiler technology and discloses a steam-water separation device for a Class D boiler. It includes a boiler body and an evaporator tube located inside the furnace chamber. A lower header is located at the bottom of the boiler body, and an upper header is located at the top. The upper and lower ends of the evaporator tube are connected to the upper and lower headers, respectively. The evaporator tube contains saturated water, and a steam-water separation device is located at the top of the evaporator tube, with a gap between the device and the water surface below it. Steam rises and enters a spiral steam channel, rotating rapidly upwards along the channel. Tiny water droplets in the steam, under the influence of gravity and centrifugal force, detach from the steam and fall back into the evaporator tube, significantly reducing the water content in the steam and achieving steam-water separation. This improves the quality of the steam and alleviates abnormal water level fluctuations in the heat exchange tubes. The collected water droplets reduce the supply of saturated water in the evaporator tubes to a certain extent, effectively saving energy and water resources.

This utility model discloses a high-efficiency raw material preheating device for hydrofluoric acid production, relating to the field of hydrofluoric acid processing technology. It includes support legs and a preheating box, and further comprises: a conveyor box, a feed inlet, a conveying mechanism mounted on the conveyor box, a first inclined screen plate, a second inclined screen plate, a U-shaped support plate, a preheating mechanism mounted on the U-shaped support plate, a recovery mechanism mounted on the preheating box, a striking mechanism mounted on the preheating box, and a discharge port. Through the cooperation of the conveying mechanism, the first inclined screen plate, the second inclined screen plate, the preheating mechanism, and the striking mechanism, fluorite powder is evenly transported to the first inclined screen plate. The striking mechanism causes the first and second inclined screen plates to vibrate, causing the fluorite powder to fall along the inclined screen plates, preventing accumulation. The preheating mechanism preheats the fluorite powder, improving the preheating effect. The recovery mechanism enables the recycling of heat energy, reducing waste heat.
