Abstract

The invention provides a coating machine heat recovery utilization energy-saving device, and belongs to the technical field of laser holographical product production equipment. The device solves the problems that a large amount of heat is also discharged outdoors simultaneously when existing coating machines discharge mixed waste gas outdoors, thereby generating heat energy waste. The coating machine heat recovery utilization energy-saving device comprises a residual heat recoverer, a new air induced fan and a smoke discharging fan, wherein the residual heat recoverer is provided with a new air channel and a mixed waste gas channel which are mutually sealed and insulated, a heat exchange structure is arranged between the new air channel and the mixed waste gas channel, one end of the new air channel is communicated with the environment, the other end of the new air channel is connected with a heater, the heater is communicated with a new air inlet of an oven through the new air induced fan, one end of the mixed waste gas channel is communicated with the mixed waste gas outlet of the oven, and the other end of the mixed waste gas channel is communicated with the smoke discharging fan. The device can reclaim heat of mixed waste gas to heat new air to enable fed new air to achieve certain temperature, and has the advantages of safety, reliability, energy-saving, has flexible installation and structure arrangement.

Description

technical field

[0001] The invention belongs to the technical field of laser holographic product production equipment, and relates to a coating machine, in particular to an energy-saving device for heat recovery and utilization of the coating machine. Background technique

[0002] During the production process of the laser holographic film, an information layer must be coated on the PET film, and the information layer is composed of about 20% resin and about 80% solvent. In order to dry and solidify the information layer, it must be processed after coating. A drying tunnel about 15 meters long is used for drying. The drying tunnel is divided into five sections, and the heating temperature of the five-section oven is 90°C, 110°C, 135°C, 145°C, and 90°C. Each oven is sent fresh air into the electric heater by a blower fan with an exhaust air volume of 2000 cubic meters per hour, and the hot air heated to the above temperature in the electric heater is sent into the oven to dr...
