Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 8 As shown, the automatic ash removal plate-type falling film generating device utilizing flue gas waste heat of the present invention includes a housing, n falling film units located in the housing, a suspended liquid contact box 5 , a suspension wire 6 and a siphon 7 . A solution outlet 8 is provided at the bottom of the housing. Each falling film unit includes a falling film plate 1 , an upper S-shaped planar spring 2 , a lower S-shaped planar spring 4 , a bar magnet 3 and a dust scraping device 9 . The falling film plate 1 in the n falling film units divides the inner cavity of the upper part of the casing into a flue gas heat source layer 10 and a solution layer 11 arranged at intervals. In each falling film unit, the upper S-shaped planar spring 2 , the lower S-shaped planar spring 4 and the bar mag...

Abstract

The invention discloses an automatic ash-removing plate-type falling film generating device utilizing the residual heat of flue gas, which comprises a housing, n falling film units, a suspended liquid receiving box, a suspension wire and a siphon tube, and a solution outlet is provided at the bottom of the housing ; Each falling film unit includes a falling film plate, an upper S-shaped planar spring, a lower S-shaped planar spring, a bar magnet and ash scraping device; in each falling film unit, the bar magnet and ash scraping device are located on the falling film plate Both sides; the top of the upper S-shaped planar spring is connected to the wall of the falling film plate, and the bottom is connected to the top surface of the bar magnet; the top of the lower S-shaped planar spring is connected to the bottom of the bar magnet, and the bottom is connected to the suspension On the hanging liquid tank; the siphon is located in the hanging liquid tank. The falling film generating device uses the principle of siphon, and by setting an S-shaped planar spring for automatic reciprocating cleaning, the spring on the wall of the falling film can automatically reciprocate, effectively inhibiting the generation of channel flow or stream flow, homogenizing the distribution of the liquid film, and having automatic cleaning. dirt function.

Description

technical field [0001] The invention belongs to the technical field of absorption refrigeration utilizing waste heat of flue gas, and in particular relates to an automatic ash-removing plate type falling film generating device utilizing waste heat of flue gas. Background technique [0002] Most of the existing absorption refrigeration generators are immersion type and spray type. The immersion type generator is greatly affected by the static pressure of the liquid, which will increase the saturation temperature of the solution inside the liquid, weaken the driving force and reduce the out of range. The spray generator can effectively overcome the influence of hydrostatic pressure, but it is difficult to completely wet the heat transfer surface, and the heat transfer effect will also be affected. Using a falling film generator can effectively avoid the influence of the static pressure of the solution. However, due to the change of the physical properties of the falling film ...
