Direct connection heating self-compressing unit for high-rise building

Abstract

This high-rise building is directly connected to the heating self-pressurization unit, which is composed of a water injector 1, a check valve 2 and a piping system; there is a water suction pipe section 3 in front of the check valve 2, which can be connected with the water supply pipe of the municipal heating pipe network, and the water supply pipe can be stopped. The water outlet pipe section 4 behind the return valve 2 can be connected with the water suction pipe of the high-rise building directly connected to the heating unit through the water ejector 1; it is characterized in that: the water inlet pipe section 5 of the water ejector 1 can be connected with the main return pipe of the heating system in the high area, The outlet pipe section 6 can be connected with the water suction pipe of the direct-connected heating unit of the high-rise building, and the water injector 1 ejects the heating water supply in the low area of ​​the pipe section 4, so as to improve the dynamic pressure head of the direct-connected heating unit of the high-rise building to absorb water, and reduce the power consumption of the high-rise heating unit. At the same time, the hot water required for heating conditions is prepared. It has the following advantages. It can be debugged and operated only by connecting the relevant pipelines. It is safe and reliable, easy to maintain, low in cost, easy to popularize, and saves electric energy. It brings great convenience for high-rise buildings and buildings with large terrain height difference to use urban external network heating, and provides reliable and energy-saving equipment for heating systems to prepare hot water under different working conditions.

Description

technical field [0001] The invention relates to an improvement of a heating system loop, in particular to a method for making the high and low areas of a high-rise building adopt the same heating water system. High-rise buildings are directly connected to heating self-pressurizing units. That is, part of the high-pressure return water of the heating system in the high-rise area is injected into the external heating network of the low-area heating system through the water injector to supply water to the suction pipe section directly connected to the heating unit of the high-rise building. Background technique [0002] High-rise buildings continue to increase. Many high-rise building direct-connection heating units have been developed around the direct connection heating between the heating system of high-rise buildings and the urban heating pipe network. The first is that the low area is heated by the municipal heating pipe network, and the high area is pressurized by a boo...

Problems solved by technology

But they all have a common defect. The potential energy of the return water in the high area is consumed by the flow breaker, pressure reducing valve, blocker, etc., and the return water pressure in the high area is not fully utilized, which does not meet the energy saving requirements.
