Heat supply and exhaust system for natatorium

Abstract

The invention discloses a heat supply and exhaust system for a natatorium. A fire grate biomass boiler is mainly used for keeping constant temperature for pool water, and a tail gas pipe of the fire grate biomass boiler is connected to an air induction fan; a static bed biomass boiler is mainly used for supplying heat and hot bathing water to the natatorium, and the natatorium is provided with a heat pump system composed of an indoor heat pump unit and an outdoor heat pump unit; a coupling and a fan shaft of the air induction fan are assembled in a threaded mode, a fan impeller and the fan shaft of the air induction fan are assembled in a threaded mode, and the thread rotation direction is the automatic locking direction along with working and bearing; the fan impeller is in threaded and rigid connection with the fan shaft after pressing a copper-lead torsion composite pad; the coupling and the other end of the fan shaft are connected rigidly through a clamp part. According to the system, tail gas heat of the boilers is fully recycled, ventilation of the natatorium is realized, the disassembly and assembly technology of the air induction fan of the boiler is greatly modified, the problems that the air induction fan of the boiler is continuously and automatically locked and is difficult to disassemble under the loading effect due to threaded assembly can be effectively solved, and large boiler fans can be disassembled conveniently and quickly after being locked in a threaded mode.

Description

technical field [0001] The invention relates to a heating and exhaust system for a natatorium with an induced draft fan which is easy to disassemble and maintain. 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 an...

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
