Integrated type heat recovery sewage source heat pump unit based on internet-of-things technology

Abstract

The invention provides an integrated type heat recovery sewage source heat pump unit based on the internet-of-things technology and belongs to the field of environmental friendliness. The integrated type heat recovery sewage source heat pump unit comprises a sewage source heat pump unit body, a sewage treatment and heat exchanging system, a hot water circulating pump and a network intelligent control box; the sewage source heat pump unit body comprises a compressor, an oil separator, a condenser, a dry filter, an electromagnetic valve, an expansion valve, an evaporator and a gas-liquid separator; and the sewage treatment and heat exchanging system comprises a sewage tank, a sewage circulating pump, a hair collector, a sand filter tank and a plate type heat exchanger. According to the integrated type heat recovery sewage source heat pump unit based on the internet-of-things technology, data are detected through temperature sensors, a liquid level sensor and pressure sensors and transmitted to a network controller through a communication transmission module, all the collected data are analyzed and processed by the network controller, and thus the function that the integrated type heat recovery sewage source heat pump unit is subjected to remote monitoring, operation, maintenance and software automatic upgrading through terminals such as a mobile phone, a PC and a PDA can be achieved. Signals are transmitted to the network controller through the Ethernet by the communication transmission module.

Description

technical field [0001] The invention relates to the technical field of sewage source heat pumps, in particular to an integrated heat recovery sewage source heat pump unit based on Internet of Things technology. Background technique [0002] The existing sewage source heat pump systems all use cold water or tap water to directly enter the sewage source heat pump unit to heat and then produce hot water. temperature. At the same time, due to the water quality of the sewage, the sewage needs to be treated multiple times, such as the need to add sewage tanks, sedimentation tanks, hair collectors, filters, etc., resulting in a complex sewage source heat pump system, especially the sewage pools that require civil construction, occupying an area The large area is more suitable for the newly constructed sewage source heat pump system. [0003] In addition, the comprehensive efficiency of the conventional sewage source heat pump unit is low, and the water output is low. At present,...

AI Technical Summary

Problems solved by technology

At the same time, due to the water quality of the sewage, the sewage needs to be treated multiple times, such as the need to add sewage tanks, sedimentation tanks, hair collectors, filters, etc., resulting in a complex sewage source heat pump system, especially the sewage pools that require civil construction, occupying an area Large area, more suitable for newly constructed sewage source heat pump system

[0003] In addition, the overall efficiency of conventional sewage source heat pump units is low, and the water output is low

At present, a large amount of domestic sewage or bathing wastewater is directly discharged into the municipal sewage pipe network. This wastewater not only has a high temperature (usually up to 28-32 degrees), but also contains a large amount of heat energy. Without any recovery When it is used, it is directly discharged, causing a lot of energy waste, which obviously does not meet the requirements of energy conservation and environmental protection.

[0004] At present, during the use of domestic sewage source heat pump systems after installation, it is necessary to monitor and control the heat pump unit, the temperature and liquid level of sewage, and the dirty and clogged filters. , unable to guarantee normal hot water supply for customers

At the same time, the sewage source heat pump system requires regular maintenance of equipment, but the sewage source heat pumps are spread all over the country, requiring equipment manufacturers or energy-saving service providers to invest a lot of manpower and material resources, which increases the operating cost of the enterprise and reduces the market competitiveness of the enterprise
