Temperature control system for non-Newtonian high-viscosity fluid conveying

Abstract

The invention discloses a temperature control system for non-Newtonian high-viscosity fluid conveying. The temperature control system comprises a conveying main pipe, conveying branch pipes, main pipeheat exchangers and a constant-temperature water tank, wherein a plurality of conveying branch pipes are positioned on the portion, behind the main pipe heat exchangers, of the conveying main pipe and correspondingly connected with the conveying main pipe; a plurality of main pipe heat exchangers are shell-and-tube heat exchangers and are arranged on the conveying main pipe in series at intervals; a first temperature sensor is arranged on the portion, corresponding to the front portion of the main pipe heat exchanger at the foremost end, of the conveying main pipe; a second temperature sensoris arranged on the portion, corresponding to the rear portion of the main pipe heat exchanger at the rearmost end, of the conveying main pipe; and the first temperature sensor, the second temperaturesensor and the constant-temperature water tank are connected with a control unit, and the control unit can conveniently adjust the temperature of the constant-temperature water tank according to thereal-time temperature transmitted by the second temperature sensor. The temperature control system is high in heat exchange efficiency, the temperature of all use points of non-Newtonian high-viscosity fluid can be effectively controlled, and the temperature fluctuation range of each use point is small.

Description

technical field [0001] The invention belongs to a temperature control system for fluid transportation, in particular to a temperature control system for non-Newtonian high-viscosity fluid transportation. Background technique [0002] Non-Newtonian fluids widely exist in daily life and production. In the process of automobile manufacturing, most of the sealants used in gluing operations are non-Newtonian fluids. During the gluing operation, the non-Newtonian fluid needs to be transported to the point of use. During this process, it needs to pass through pipes, filters, pressure regulators and ball valves, etc., which will inevitably cause changes in the internal shear rate of the non-Newtonian fluid, resulting in non-Newtonian fluids. The potential energy of the Newtonian fluid is converted into heat energy, which in turn causes the temperature of the non-Newtonian fluid to change. At present, the most effective method is to control the temperature at the point of use to ensu...

Problems solved by technology

However, the temperature control mode of the winding heating cable can only heat the fluid, and cannot cool down when the external environment temperature is high; the temperature control method of the pipe-in-pipe heat exchanger is used for the main delivery pipe. A very long installation space is required for installing the tube-in-tube heat exchanger, which requires high installation space, and at the same time causes high manufacturing costs, and the non-Newtonian high-viscosity fluid has a low thermal conductivity. The heat exchange of the tube-in-tube heat exchanger is adopted. less efficient
