Heating system for natatorium

Abstract

The invention discloses a heating 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 mainly keeps constant temperature of pool water; a fixed bed biomass boiler is mainly in charge of heating the natatorium and supplying 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 heating system for the natatorium deeply 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 heating system for a natatorium with an induced draft fan which is easy to disassemble and repair. Background technique [0002] If the swimming pool is to be opened in winter, it must have a good heating system. The heating of the swimming pool includes constant temperature heating for pool water, heating for bathing water, and heating for heating, etc. Due to the low temperature in winter, the required The heat supply is relatively large, and because of the large 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 and heating. Good heat recovery and dust removal...

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
