Heat exchange method suitable for marine industry

Abstract

The invention discloses a heat exchanging method suitable for aquatic product industry, the thin impermeable materials (such as plastic paper and rainproof silk and so on) which are cheap and easy to obtain are taken as heat exchanging materials, the heat exchanging materials are made into cylinder shape, one side of the cylinder is fixed at bottom of the water storing pool, the production waste water can be injected into one end of the cylinder and can be flown from the other end of the cylinder, the shape can be kept by external forces (mounting float and support and so on), when heat exchanging, the cross section is flat long-shaped, so that the production waste water can exchange heat with the sea water in the water storing pool when the production waste water flows through the cylinder. The main purpose of the invention is to recovery the waste water residual heat generated in the production process, the objective for effectively reducing the production cost can be reached.

Description

1. Technical field [0001] The invention belongs to the technical field of aquaculture and seedling cultivation, and in particular relates to a method for heat exchange in the aquatic industry. 2. Background technology [0002] At present, in the field of aquaculture and nursery, the well-known aquaculture and nursery industry has the characteristics of high risk and high output. The high risk is mainly reflected in the heating of seawater by boilers and the cooling of seawater by refrigerators. These two aspects need to consume a lot of coal and electricity, which consumes a lot of energy and high production costs. In recent years, in order to save costs, many companies have begun to seek other methods to reduce production costs, such as using deep well groundwater to exchange heat with natural seawater, but because they use stainless steel or titanium steel and other materials, the cost is high, and deep wells The groundwater is limited and consumes a lot of electric energ...
