Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Please also refer to Figure 1 to Figure 3 , the waste water heat recovery heating system provided by the present invention is now described. The waste water heat recovery heating system includes a liquid infusion pipe 22 , a heat exchange pipe 4 , a methane tank 21 and an insulating material 16 . The infusion pipe 22 is pierced with a connecting pipe 1, and a plurality of baffles 3 are arranged between the connecting pipe 1 and the infusion pipe 22; the water inlet 8 of the infusion pipe 22 is used for passing high-temperature waste water. The heat exchan...

Abstract

The invention provides a wastewater heat recovery heating system, and belongs to the technical field of heat recovery. The system comprises a liquid conveying pipe, a heat exchange pipe and a biogas digester, wherein the heat exchange pipe is arranged on the outer side of the liquid conveying pipe in a sleeving mode, a heat exchange cavity is defined by the heat exchange pipe and the liquid conveying pipe, a liquid inlet of the heat exchange pipe is used for introducing low-temperature return water into the heat exchange cavity, and a liquid outlet of the heat exchange pipe communicates with a combustor; the outer side of the biogas digester is wrapped with a thermal insulation material, the thermal insulation material and the outer wall of the biogas digester form a wastewater circulating channel, and a flow dividing piece is arranged at the top of the biogas digester and communicates with a water outlet of the liquid conveying pipe through a conveying pipe; the flow dividing piece is used for dividing wastewater subjected to heat exchange into the wastewater circulating channel; a gas outlet of the biogas digester communicates with the combustor through a pipeline and is used for conveying biogas into the combustor; and the bottom of the biogas digester communicates with a water pump through a liquid discharging pipe. According to the wastewater heat recovery heating system, under the condition of low cost, secondary heating is realized, energy input is reduced, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of heat recovery, and more specifically relates to a waste water heat recovery heating system. Background technique [0002] In the production process of cast pipe enterprises, a large amount of high-temperature wastewater will be generated. If this part of wastewater is directly discharged, it will inevitably cause waste of resources. Although there is an existing heating system that recovers heat from wastewater, due to the low heat exchange efficiency and the temperature difference between the circulating water in the heating system and the high-temperature wastewater, the heat recovery effect is not obvious, and a large amount of energy is still consumed , to meet daily needs. Contents of the invention [0003] The purpose of the present invention is to provide a waste water heat recovery heating system, which aims to solve the problem that the circulating water in the heating system is not much diffe...
