Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027]It can be seen from Fig. 3 that the present invention includes water seals and water seal buoys (44, 45, 46, 47), electric water valves (48, 49, 50, 51) and PLC programmable controller 52, which together constitute an adsorption refrigeration system The cooling water input and exhaust gas or gas input automatically control the switching mechanism. Here, the exhaust gas or gas adsorption refrigeration system of 4 generators is taken as an example, and the switching between the adsorption state and the desorption state of the generator is explained. Figure 1 shows the function of water seal and water seal buoy to close and open the flue in a single generator. In the figure, the generator inner casing 31 and the tail gas or gas input sub-pipe 40 are designed as one with the flue, and the water and water-sealed buoy 39 will close the tail gas or gas input sub-pipe 40. Or...

Abstract

The invention relates to a flue water seal buoy switch device for absorbing a refrigeration system by using tail gas or fuel gas, comprising a PLC (programmable logic controller) (52), a cooling water input program controlled valve group (21), a tail gas or fuel gas input program controlled valve group (20) and N generators with water seal buoys and being characterized in that: the PLC (52) is respectively connected with the tail gas or a fuel gas input program controlled valve group (20) and N electric water valves in the cooling water input program controlled valve group (21), each of the electric water valves is connected with inlet and outlet pipes of the generators through pipes, each of the tail gas or fuel gas input program controlled valve group (20) is connected with tail gas or fuel gas input pipeline of the generators, and N is equal to 2-12. The automatically controlling switch device of the invention can guarantee that each of the generators in the refrigeration system in the absorbing refrigeration system carries out heating desorption and cooling absorption and switches based on a set program so as to realize continuous and stable refrigeration.

Description

technical field [0001] The invention relates to a switching device of an adsorption refrigeration system, in particular to a switching device of a flue water-seal buoy for an adsorption refrigeration system with two or more generators using tail gas or gas. Background technique [0002] In the past, the flue switching devices of two or more generator exhaust or gas adsorption refrigeration systems used mechanical smoke plate valve structures, and the switching mechanism had the following defects: [0003] Due to the high temperature of exhaust gas and gas at about 400-800°C, it is difficult to find a sealing material suitable for the mechanical smoke plate valve, so there are problems of air leakage and water leakage [0004] ·Mechanical smoke plate valve has the problem of seawater corrosion. [0005] ·The machining precision of the mechanical smoke plate valve is high, resulting in high processing cost and long cycle time. Contents of the invention [0006] The object ...
