Heat source flow equilibrium control device and using method thereof

Abstract

The invention relates to the technical field of heating devices, in particular to a heat source flow equilibrium control device and a using method thereof, wherein the heat source flow equilibrium control device comprises a heat source section and a pipe conveying section, a first branch is connected with a second branch through a gas boiler, the water outlet of a third branch is communicated with a first water inlet of an energy mixing device, the tail end of the water return main pipe is respectively communicated with the water inlet of the third branch and the water inlet of the first branch, the water outlet of the second branch is communicated with a second water inlet of the energy mixing device, and the water outlet of the energy mixing device is communicated with a water supply total pipe through an outer-net circulating pump. The heat source flow equilibrium control device is reasonable and compact in structure and convenient to use, the power of a burner can be controlled in real time according to temperature change and requirements, the labor cost is reduced, the control precision is improved, and the device is more energy-saving and environment-friendly; the power and the size of the gas boiler can be both reduced, the purchase cost of the gas boiler is lowered, the occupied area of the gas boiler is reduced, and the noise generated during work of the gas boiler is reduced.

Description

technical field [0001] The invention relates to the technical field of heat supply device control devices, and relates to a heat source flow balance control device and a method for using the same. Background technique [0002] At present, the central heating in the city mainly uses large boilers as the heat source, and then the heat medium is transmitted to the first-level pumping station and the second-level pumping station through the pipeline, and finally delivered to the user's home through the second-level pumping station or the third-level pumping station. In the single-circulation heating process of this large boiler, the adjustment of the heat supply is realized by adjusting the combustion power of the boiler, that is, the circulation flow rate remains unchanged, and the temperature of the water body is changed. Therefore, no matter how much heat is needed at the hot end, the circulation pump needs to push all the circulating water into the boiler for heating. In thi...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a heat source flow balance control device and its use method, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem of centralized power supply of existing large boilers. The power of the circulating pump and boiler required in the thermal mode is large, the purchase cost is high, the power consumption of the circulating pump is large, the cost of use is high, and the problem of not being energy-saving and environmentally friendly, the size of the boiler is large, and the installation area is large. The problem of high noise during use, and the adjustment of the boiler is carried out manually, which requires uninterrupted work, high labor intensity and low work efficiency.
