Mine three-proof heat exchanger

Abstract

The invention discloses a mine three-proof heat exchanger, which comprises a streamline type shell, a heat exchanging bundle positioned in the shell, and a plurality of baffle plates, wherein the plurality of baffle plates are sequentially arranged along the direction of the cross section of the shell; the baffle plates are provided with water flow passageways; the water flow passageways among the baffle plates are kept at a certain inclined angle; the peripheries of the baffle plates are fixed on the inner wall of a shell; and the heat exchanging bundle is axially penetrated through the water flow passageways of the baffle plates along the shell. The water flow passageways on the baffle plates baffle and limit the direction of industrial water, therefore, the mine three-proof heat exchanger reduces the flow speed of the water flow, guarantees the water flow to be adequately and evenly contacted with the outer wall of the heat exchanging bundle, greatly improves the energy exchange, reduces the production cost, improves the economic benefit and the social benefit of enterprises, and is particularly suitable for various mines which contain water inflow with high impurity content, high mineralization and high corrosivity.

Description

technical field [0001] The invention relates to a heat exchanger for mine water gushing, which belongs to the field of coal mine water gushing heat or cold energy utilization, in particular to a mine water gushing energy conversion device that can be directly used for the energy conversion of mine water gushing with many particles, impurities, high salinity, and high corrosiveness. Three anti-heat exchangers. Background technique [0002] Mine gushing water is a kind of groundwater that gushes out from rock formations during mine excavation, and has the characteristics of many particles and impurities, high salinity, and high corrosiveness. In the case that it is not used as the energy source of the heat or cold energy utilization system, the method of setting up water tanks is generally used to collect different levels of mine water, and then pump it to the surface through the pumping station. Initially, it is directly discharged as waste water. Afterwards, it is used as a...

Problems solved by technology

[0003] When the mine water is used as the heat source or cold source of the water source heat pump, it needs to go through the water treatment and purification process, that is, the mine water needs to go through a relatively complicated physical and chemical treatment process to meet the water quality requirements of the water source heat pump. It will cause damage to the water source heat pump unit, causing it to fail to work normally.

Mine water gushing in my country's coal mines often has the characteristics of many particles, impurities, high salinity, and high corrosiveness. Due to the limitations of the equipment, the equipment is relatively large, with a large area and a high height, which cannot be adapted to narrow spaces such as roadways and chambers, resulting in large energy losses, high investment, complex processes, and difficult construction of the entire thermal or cold energy utilization system. high
