Double-temperature hot water system for natatorium

Abstract

The invention discloses a double-temperature hot water system for a natatorium. A tail gas tube of a fire grate biomass boiler is emptied after being connected with a tubular heat exchanger through an induced draft fan; the fire grate biomass boiler carries out constant temperature keeping and heating on pool water; a fixed bed biomass boiler supplies bathing hot water; a coupling of the induced draft fan is in threaded assembly with both a fan shaft and a fan impeller; the thread turning direction is in a working and bearing automatic locking direction; the fan impeller forms threaded rigid connection with the fan shaft after compacting a copper-lead torsion compound pad; and the coupling also forms threaded rigid connection with the other end of the fan shaft through a hoop part. The double-temperature hot water system for the natatorium supplies double-temperature hot water, recovers tail heat of the boiler, more importantly transforms the disassembly and assembly technology of the induced draft fan of the boiler dramatically, can efficiently solve the problem of difficulty in disassembly as threaded assembly of the induced draft fan of the boiler is continuously automatically locked under the loading action and is particularly suitable for convenient and rapid disassembly of a fan of a large boiler after being in threaded locking.

Description

technical field [0001] The invention relates to a dual-temperature hot water system in a swimming pool which is convenient for dismantling and maintenance of an induced draft fan. Background technique [0002] If the swimming pool is to be opened in winter, it must first have a good hot water system, including bath water heating and pool water constant temperature heating, referred to as a dual-temperature hot water system. Due to the low temperature in winter, the required heat supply is relatively large , and because there is a big difference between the temperature of the pool water and the temperature of the bathing water in winter, two boilers are generally required to meet the needs. [0003] Because the biomass fuel used in the biomass boiler is renewable, and the tail gas has low toxicity, easy natural degradation, and low pollution, it can also be used in densely populated residential areas, and can be used as a heat source for swimming heating. Good heat recovery ...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
