Description

Technical Field

[0001] This utility model relates to the field of enameled wire technology, and in particular to a heat recovery device for treating waste gas in enameled wire production. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked.

[0003] The production of enameled wire generates exhaust gas, which contains a large amount of heat, solid particles, and harmful gases. The exhaust gas needs to be purified before it can be discharged.

[0004] Heat in exhaust gas is usually recovered using waste heat recovery equipment. However, the existing waste heat recovery equipment has a relatively simple structure, which only recovers waste heat through heat exchange tubes with heat exchange medium. As a result, the heat cannot be fully recovered and utilized during the time the exhaust gas circulates in the equipment, resulting in energy waste. Utility Model Content

[0005] The purpose of this invention is to provide a heat recovery device for treating waste gas in enameled wire production. This invention has the advantages of high heat recovery efficiency and reduced energy waste.

[0006] The technical solution of this utility model: a heat recovery device for treating waste gas in enameled wire production, comprising a housing, heat exchange units distributed within the housing, a support base correspondingly located below the housing, and a lifting mechanism located between the support base and the housing; an air inlet pipe is provided on the upper left side of the housing, and an air outlet pipe is provided on the lower right side; the heat exchange unit includes a water inlet pipe located on the upper left side of the housing, a water outlet pipe located on the lower right side, multiple heat exchange pipes correspondingly distributed within the housing, and a connecting bend pipe located outside the housing connecting adjacent heat exchange pipes; multiple air guide plates are correspondingly provided within the housing.

[0007] In the aforementioned heat recovery device for treating waste gas in enameled wire production, the heat exchange tubes are arranged horizontally, and multiple layers are arranged inside the box from top to bottom, with multiple heat exchange tubes arranged horizontally in each layer; the outside of the box is provided with a water distribution pipe connected to the inlet pipe and the outlet pipe respectively; one side of the water distribution pipe is connected to the inlet pipe or the outlet pipe, and the other side is connected to the corresponding multiple heat exchange tubes.

[0008] In the aforementioned waste gas treatment and heat recovery device for enameled wire production, each of the aforementioned air guide plates is located below the corresponding heat exchange tube; the air guide plates are staggered in the box, with one end connected to the side wall of the box and the other end having a gap with the side wall of the box; the air guide plates form a meandering air passage in the box.

[0009] In the aforementioned waste gas treatment and heat recovery device for enameled wire production, each of the aforementioned air guide plates is set at an angle downwards.

[0010] In the aforementioned waste gas treatment and heat recovery device for enameled wire production, the lifting mechanism includes lifting seats located at the four corners of the bottom of the housing, a lifting machine located on a support seat, and a limiting guide bar vertically located on the support seat; the top of the lifting rod of the lifting machine is connected to the bottom of the lifting seat; the top of the limiting guide bar penetrates through the lifting seat.

[0011] In the aforementioned waste gas treatment heat recovery device for enameled wire production, a plurality of correspondingly distributed dust collection chambers are provided at the bottom of the housing, and each dust collection chamber is provided with a vertically arranged detachable dust collection bag; the opening direction of each dust collection bag corresponds to the gas flow direction; and an inspection door corresponding to the dust collection chamber (71) is provided on the outside of the housing.

[0012] Compared with the prior art, this application sets multiple heat exchange tubes in the box, and sets inlet and outlet water pipes on the left and right sides of the box respectively, so that the heat exchange medium can enter from the upper left side of the box, flow through the box multiple times, and then flow out from the lower right side of the box.

[0013] Meanwhile, multiple corresponding air guide plates are installed inside the box. The exhaust gas enters the box from the top, flows meanderingly along the air channels formed by the air guide plates, and is then discharged from the bottom of the box, extending the circulation time of the exhaust gas inside the box. This allows for full recovery of heat from the exhaust gas, resulting in high heat recovery efficiency.

[0014] Therefore, this utility model has the advantages of high heat recovery efficiency and reduced energy waste. Attached Figure Description
