Description

Technical Field

[0001] This utility model relates to the field of heating and water supply technology, specifically a desulfurization zero-emission hot water system heating station. Background Technology

[0002] Heating water supply refers to the process of transferring heat from a heat source to a building through a hot water system, with the primary purpose of providing a warm indoor environment. A heating water supply system typically consists of three parts: a heat source, heat transmission pipes, and heat dissipation equipment. In practical applications, hot water heating systems can be divided into general hot water heating systems and high-temperature hot water heating systems based on the supply water temperature. Furthermore, based on the different circulation methods, they can be divided into natural circulation and mechanical circulation systems. Heating water supply systems in modern buildings offer excellent heating performance, high comfort, low operating costs, and ease of operation.

[0003] A heating station water supply device, as disclosed in announcement number CN119508869A, includes a pipeline system and a control system. The pipeline system includes a boiler blowdown recovery water pump, a demineralized water source, and a water supply pipeline. The input end of the water supply pipeline is connected to the demineralized water supply to the heating station, and the output end of the water supply pipeline is connected to a circulating pump of the heating station. The output ends of the circulating pump are connected to the dormitory area and the production area, respectively. This invention adds a pipeline from the outlet of the boiler blowdown recovery water pump to the water supply pipeline. The outlet of the boiler blowdown recovery water pump remains normally open. When the boiler blowdown recovery water pump is running, it can guarantee the normal water supply to the heating station without needing to activate the demineralized water source. When the boiler blowdown recovery water pump stops, it can automatically activate the demineralized water source. Therefore, using water from the boiler blowdown recovery water tank to supplement the water supply to the heating station can greatly save the amount of old brine used, achieving energy saving.

[0004] The aforementioned devices consume a lot of energy and are not environmentally friendly in existing heating stations during use; therefore, we propose a desulfurization zero-emission hot water system for heating stations to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a desulfurization zero-emission hot water system heating station to solve the problems of high consumption and environmental unfriendliness of existing heating stations mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization zero-emission hot water system heating station, comprising a heating station, a main outlet pipe on one side of the heating station, an isolation door on the other side of the main outlet pipe, a zero-emission hot water pump outlet pipe in front of the isolation door and connected to the zero-emission hot water pump outlet pipe, a zero-emission hot water pump return pipe behind the isolation door and connected to the zero-emission hot water pump return pipe, the zero-emission hot water pump outlet pipe and the zero-emission hot water pump return pipe being symmetrically arranged on both sides of the zero-emission hot water tank, a circulation module at the rear end of the zero-emission hot water tank, a heat exchange module at the rear end of the circulation module, a desulfurization module on one side of the heat exchange module, a flow guiding module at the front end of the zero-emission hot water tank, and a user module on the other side of the flow guiding module.

[0007] Preferably, a return water header is provided on the other side of the user module, and the other side of the return water header is connected to the heating station pipeline.

[0008] Preferably, an isolation door is provided inside the return water header.

[0010] Preferably, the circulation module is provided in two sets and symmetrically arranged between the zero-emission hot water tank and the flue gas heat exchanger. Each set of circulation modules includes a circulation pump and a connecting pipe. There are two sets of circulation pumps, and a connecting pipe is provided between the two sets of circulation pumps. Both sets of circulation pumps are connected to the flange at the connection port of the zero-emission hot water tank and the flue gas heat exchanger.

[0011] Preferably, the desulfurization module includes a primary desulfurization absorption tower, a secondary desulfurization absorption tower, and absorption tower connecting pipes. The primary desulfurization absorption tower is located on the right side of the flue gas heat exchanger and is connected to the flue gas heat exchanger via a pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model solves the problem of high energy consumption in existing heating stations by taking out the heating module of the heating station separately and replacing the water heating with a heat exchange module.

[0015] (2) By setting a desulfurization module at the back end of the heat exchange module, the sulfur generated by combustion is separated by the desulfurization module, and then the desulfurized gas is discharged, thus solving the problem of the existing heating station being not environmentally friendly.
