Abstract
The utility model discloses a forced circulation heat exchanger which comprises a shell-and-tube heat exchanger, a separator and a forced circulation pump, wherein a lower end outlet of the separator is connected with a lower end inlet of the shell-and-tube heat exchanger through the forced circulation pump; an upper end outlet of the shell-and-tube heat exchanger is connected with the separator through a pipeline; a cold liquid chamber, a heat exchange chamber and a hot liquid chamber are arranged on the shell-and-tube heat exchanger from bottom to top in sequence and are in tight connection through the periphery wall; the cold liquid chamber and the heat exchange chamber are separated by a baffle; the heat exchange chamber and the hot liquid chamber are mutually communicated; the heat exchanger chamber is provided with a steam inlet and a condensing water outlet; a plurality of heat exchange tubes which are arranged in the longitudinal direction are arranged inside the heat exchanger chamber; the lower parts of the heat exchange tubes penetrate through the baffle plate and stretch into the cold liquid chamber; a spiral guide device is arranged on each heat exchange tube and at a position on the baffle in the cold liquid chamber; and a liquid discharge is formed at the upper end of each heat exchange tube. The forced circulation heat exchanger is simple in structure, free of scale on the heat exchange tubes and low in maintenance and operation cost.
Description
Technical field
The utility model relates to the concentrated field of the materials such as chemical synthesis, chemical fertilizer production, food, is specifically related to a kind of forced circulation heat exchanger.
Background technology
In the prior art, forced circulation heat exchanger process unit as shown in Figure 1, comprise tubular heat exchanger 1, separator 2 and forced circulation pump 3, the lower end outlet of separator 2 is connected by forced circulation pump 3 with the lower end entrance of tubular heat exchanger 1, the outlet of the upper end of tubular heat exchanger 1 and separator 2 are connected by pipeline, the cooling liquid chamber 4 that tubular heat exchanger 1 sets gradually from top to bottom, Heat Room 5 and hydrothermal solution chamber 6, mutually connect between cooling liquid chamber 4 and the Heat Room 5, mutually connect between Heat Room 5 and the hydrothermal solution chamber 6, Heat Room 5 is provided with steam inlet 8 and condensation-water drain 9, be provided with the heat exchanger tube 7 of some longitudinal arrangements in Heat Room 5, the top and bottom of every heat exchanger tube 7 are provided with leakage fluid dram and inlet.This construction forces circulation heat exchanger, liquid are laminar condition after entering heat exchanger tube 7, therefore need coutroi velocity non-scaling in 2～3m/s guarantee heat exchanger tube to stop up, and the flow velocity height causes internal circulating load large, so power consumption is high, operating cost is high.
Summary of the invention
The purpose of this utility model just is to address the above problem, and a kind of forced circulation heat exchanger is provided, and can not only heat the concentrated liquid material, can also energy efficient, reduce the heat exchange area of heat exchanger.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of forced circulation heat exchanger comprises tubular heat exchanger, separator and forced circulation pump, it is characterized in that: the lower end outlet of described separator is connected by forced circulation pump with the lower end entrance of tubular heat exchanger; The upper end outlet of described tubular heat exchanger is connected by pipeline with separator; Described tubular heat exchanger sets gradually from top to bottom passes through perisporium be tightly connected cooling liquid chamber, Heat Room and hydrothermal solution chamber, is separated by baffle plate between cooling liquid chamber and the Heat Room, mutually connects between Heat Room and the hydrothermal solution chamber; Heat Room is provided with steam inlet and condensation-water drain; Be provided with the heat exchanger tube of some longitudinal arrangements in Heat Room, the bottom of heat exchanger tube is passed baffle plate and is extend in the cooling liquid chamber, and every heat exchanger tube part in the cooling liquid chamber on baffle plate is provided with spiral flow-guiding device, and the upper end of every heat exchanger tube is provided with leakage fluid dram.
Described heat exchanger tube is columnar straight tube, and described spiral flow-guiding device is to be close to the setting of heat exchanger tube inwall.
The utility model has the advantage of: 1, the utility model apparatus structure is simple, add spiral flow-guiding device in the heat exchanger tube lower end, liquid material is risen in the shape of a spiral, form turbulence state, therefore reducing flow velocity makes it can guarantee the heat exchanger tube non-scaling at 1.5～2m/s, the flow velocity reduction causes the forced circulation amount to reduce, and saves operation power consumption and cost of investment; 2, liquid material is the turbulent flow rising, and heat transfer coefficient increases, and has therefore reduced the heat exchange area of heat exchanger.
