Abstract

The invention relates to a booster-type discharge flue waste heat recycling device which comprises a boiler and a waste heat exchanger, and the boiler and the waste heat exchanger are installed on the ground. A smoke outlet of the boiler is connected with the waste heat exchanger through a first smoke pipe. A second smoke pipe is connected to the position of an outlet of the waste heat exchanger. The second smoke pipe is provided with an energy saver which is connected with a water supply pump through a water inlet. A steam outlet is further formed in the top of the waste heat exchanger. The first smoke pipe is further connected with a first booster pump through a branch pipe. The second smoke pipe is further connected with a second booster pump through a branched pipe. The waste heat exchanger comprises a smoke flue and an S-shaped pipe fixedly installed in the smoke flue. Smoke discharge sheets are installed between every two adjacent vertical sections of the S-shaped pipe, and the multiple smoke discharge sheets are arranged at intervals in an up-and-down mode. Each smoke discharge sheet comprises two smoke discharge loops which are arranged on the corresponding vertical section in a sleeving mode. Each smoke discharge loop is provided with filter holes.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat recovery and utilization system. Background technique [0002] The gas-fired heat carrier boilers in the prior art have a low recycling rate, which often causes waste of energy. Contents of the invention [0003] In view of the above-mentioned deficiencies existing in the prior art, the applicant conducts research and improvement, and provides a pressurized smoke exhaust channel waste heat recovery and utilization device. The present invention adopts the following scheme: [0004] A pressurized smoke exhaust channel waste heat recovery and utilization device, including a boiler installed on the ground and a waste heat heat exchanger, the smoke outlet of the boiler is connected to the waste heat heat exchanger through the first flue gas pipe, and the waste heat exchanger The outlet of the heater is connected to the second flue gas pipe, and an economizer is ...
