Abstract

The invention discloses a tunnel furnace with an energy recycling system, which comprises an inlet section, a furnace pipe body, an energy recovery section and an outlet section which are sequentially connected, and the energy recovery section comprises a cooling channel body and an energy recovery area arranged outside the cooling channel body. The inlet section comprises an inlet channel body and an energy utilization area arranged outside the inlet channel body, an energy conveying body used for conveying heat-conducting media is arranged between the energy recycling area and the energy utilization area, and the energy recycling area is provided with a medium inlet used for inputting the heat-conducting media. The energy utilization area is provided with a medium outlet used for discharging the heat-conducting medium, and the medium inlet or the medium outlet is provided with a power piece used for driving the heat-conducting medium to flow. According to the tunnel furnace with the energy recycling system, energy can be recycled, and the better energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the field of tunnel furnaces, in particular to a tunnel furnace with an energy recovery and reuse system. Background technique [0002] Tunnel furnaces are often used for thermal processing of workpiece products, including but not limited to brazing, heat treatment and sintering, etc., refer to Figure 7 As shown, the process curves of most tunnel furnaces are basically composed of three stages of heating, heat preservation, and temperature reduction. The workpiece enters the furnace from the inlet section to heat up and heat up. The workpiece is kept at a certain temperature, and a heat transfer medium is generally used for heat exchange cooling during the cooling process. [0003] In the commonly used water cooling method, the cooling water directly takes away the heat of the processed workpiece, resulting in energy waste. Contents of the invention [0004] In order to recover and reuse the energy of the heat-conducting me...
