Abstract

A waste-heat utilization heat exchanger with a constant output fluid temperature comprises heat exchange tube bundles, a shell, an inlet header and an outlet header. The heat exchange tube bundles are arranged in the shell, and the two ends of each heat exchange tube bundle are connected with the inlet header and the outlet header respectively. The inlet header is provided with an inlet pipe, the outlet header is provided with an outlet pipe, and a tail gas inlet and a tail gas outlet are formed in the upper portion and the lower portion of the shell respectively. The inlet pipe is provided with a valve and a temperature sensor, and an outlet temperature sensor is arranged in the outlet pipe. The temperature sensor and the valve are both in communication connection with a central control unit. The waste-heat utilization heat exchanger is an efficient clean type heat reclaim unit and has the advantages of being strong in heat-transfer capability and the like, the outlet water temperature is kept constant by the way of controlling the flow of heat exchange fluid which is input to the heat exchanger, the technical effect that the temperature of output water is constant can be achieved, and therefore intelligent control over the heat exchanger is achieved.

Description

Technical field

[0001] The invention relates to a heat exchanger using waste heat with a constant outlet water temperature, and belongs to the technical field of heat exchangers. Background technique

[0002] With the rapid economic development of our country, energy consumption is increasing, and the problem of deteriorating urban air quality has become more and more prominent. The problems of saving energy and reducing the emission of environmental harmful substances are urgent. In the common thermal power field, one of the main reasons for high energy consumption and serious pollution is that the exhaust temperature of flue gas is too high, which wastes a lot of energy and causes environmental pollution. The cement industry is an industry with high energy consumption and high pollution. The exhaust gas produced by the cement rotary kiln contains high dust concentration and poor quality. The waste heat power generation system for cement rotary kiln can recover and reuse the w...
