Problems solved by technology

However, the strength of the fluoroplastic tube bundle itself is not strong enough, and foreign objects such as iron filings falling off in the flue will damage the tube bundle and cause leakage under the promotion of the flue gas flow rate, which greatly increases the work of leak detection, plugging and maintenance.

Embodiment Construction

[0015] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a flue 1, a fluoroplastic heat exchanger 2 is arranged inside the flue 1, and a number of anti-shock tube bundles 3 are arranged in front of the fluoroplastic heat exchanger 2. The upper and lower ends of the anti-shock tube bundle 3 are fixedly connected to the flue 1 through the upper head 4 and the lower head 5 respectively. The anti-shock tube bundle 3 is 4 rows. The anti-shock tube bundle 3 is a fluoroplastic tube with a diameter of 10 mm and a thickness of 1 mm. The inlet and outlet of the 2 tube rows of the fluoroplastic heat exchanger are respectively connected with an inlet joint flange 6 and an outlet joint flange 7 , and the 2 tube rows of the fluoroplastic heat exchanger are fixed by a fixing frame 8 . The fixed frame 8 is made of carbon steel winding fiberglass material.

Abstract

The invention belongs to the technical field of waste heat utilization of boiler smoke and particularly relates to an impact-resistant fluoroplastic heat exchanger. The impact-resistant fluoroplastic heat exchanger comprises a flue; a fluoroplastic heat exchanger is arranged in the flue; the impact-resistant fluoroplastic heat exchanger is characterized in that a plurality of impact-resistant tube bundles are arranged in front of the fluoroplastic heat exchanger. The impact-resistant fluoroplastic heat exchanger disclosed by the invention has the beneficial effects of effectively preventing or isolating impact caused by foreign materials to a heat exchanging material by arranging the impact-resistant tube bundles in front of the heat exchanger, improving the operation reliability of the heat exchanger and reducing the work of leakage inspection, blocking and overhauling.

Description

(1) Technical field [0001] The invention belongs to the technical field of waste heat utilization of boiler flue gas, and in particular relates to an anti-shock fluoroplastic heat exchanger. (2) Background technology [0002] With the in-depth research on boiler flue gas waste heat utilization technology, fluoroplastic heat exchangers are gradually being used in flue gas heat exchange systems, especially in the technical field of deeply reducing exhaust gas temperature. Corrosive, with good adaptability and reliability. However, the strength of the fluoroplastic tube bundle itself is not strong enough, and foreign matter such as iron filings falling off in the flue will damage the tube bundle and cause leakage under the promotion of the flue gas flow rate, which greatly increases the work of leak detection, plugging and maintenance. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides an anti-impa...
