Double-unit pipe shell condenser and use method thereof

Abstract

The invention discloses a double-unit pipe shell condenser which comprises a bottom plate. Two sets of symmetrically distributed bases are arranged at the upper end of the bottom plate. The upper endsof the bases and the lower portions of the two ends of the arc face of a condensation barrel are fixedly connected. Second connecting devices are arranged at the two ends of the condensation barrel,and flange plates on the outer sides in the second connecting devices are fixedly connected with the inner side of the surface of a pipe box. Pipe plates are symmetrically arranged on the two sides ofthe inner wall of the pipe box. The double-unit pipe shell condenser is simple in structure, fast and efficient in heat exchange and convenient to operate. A cooling water circulating system is adopted by double units, space is greatly saved, and the units can be started and stopped according to system load changes. When the system load is reduced to a certain degree, one unit can be automatically omitted, and the other unit operates under 60%-100% of the system load; and the economic resource and space resource of enterprises are saved, the condensation quality is guaranteed, and the use efficiency of the condenser is improved. In addition, the invention provides a use method of the double-unit pipe shell condenser.

Description

technical field [0001] The invention relates to the technical field of heat exchange and condensation equipment, in particular to a double-machine shell-and-tube condenser and a method for using the same. Background technique [0002] The condenser is a component of the refrigeration system, which is a kind of heat exchanger. It can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast way. Time is wasted due to insufficient utilization of high-power single-unit units. According to market demand, it does not match the single condensing unit. Traditional condensers have many problems, such as complex structure, low heat transfer efficiency, inconvenient operation, and single-unit operation. When the load changes and the unit is started and shut down, the economic and space resources of the enterprise are wasted more, the quality of condensation is difficult to be guaranteed, and it is incompatible with the concept of energ...

[0002] The condenser is a component of the refrigeration system, which is a kind of heat exchanger. It can convert gas or vapor into liquid, and transfer the heat in the tube to the air near the tube in a very fast way. Time is wasted due to insufficient utilization of high-power single-unit units. According to market demand, it does not match the single condensing unit. Traditional condensers have many problems, such as complex structure, low heat transfer efficiency, inconvenient operation, and single-unit operation. When the load changes and the unit is started and shut down, the economic and space resources of the enterprise are wasted more, the quality of condensation is difficult to be guaranteed, and it is incompatible with the concept of energy saving, resulting in low efficiency of the use of the condenser. Realization of shell condenser is imperative
