Abstract
The utility model discloses an overhead condenser which belongs to a tube type heat exchanger widely applied to all fields in chemical engineering production. The overhead condenser comprises a tower body; an upper sealing head and a lower sealing head are arranged at the upper end and the lower end of the tower body respectively; the upper sealing head and the lower sealing head are communicated through a plurality of sealed tubes; a vapor inlet is formed on the upper sealing head, and a condensed water outlet is formed at the bottom end of the lower sealing head; and the tower body comprises an upper tower body and a lower tower body, and a U-shaped corrugated pipe expansion joint is arranged therebetween. The corrugated pipe expansion joint is arranged between the upper tower body and the lower tower body, thereby avoiding the damage of the heat exchanger due to stress stretching caused by different expansion coefficients; a cooling water inlet is formed on a lower tower body in a position near the lower sealing head, the cooling water is fed from the tail part and flows along the tubes, thereby slowing down the flow speed, increasing the exchanged heat, lowering the manufacturing cost, and reducing the weight of equipment under the condition of equal heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of overhead condenser, belongs to tubular heat exchanger, is widely used in the every field of Chemical Manufacture.
Background technology
At present, the general shell-and-tube fixed head heat exchanger that adopts in trifluoro chlorine chrysanthemumic acid is produced, this heat exchanger comprises the tower body of integral type sealing, the two ends up and down of tower body are respectively equipped with upper cover and low head, tubulation by some sealings between described upper cover and the low head is communicated with, tubulation is fixed by stationary barrier, in use there have been various deficiencies in this heat exchanger, at first, the shell journey material and the front and back end temperature difference are big, shell coefficient of expansion difference easily causes heat exchanger to be subjected to stress fail in tension, and secondly this heat exchanger adopts stationary barrier to add strong turbulence, therefore increased the resistance that fluid passes through, strengthen the load of vavuum pump, simultaneously, between dividing plate, existed the turbulent flow dead angle, material is easily in this fouling, and the heat exchange efficiency of this kind heat exchanger is not high, increase the heat exchange area that exchange capability of heat must strengthen heat transmission equipment, thereby has increased the weight of equipment.
The utility model content
Problem to be solved in the utility model provides a kind of heat transfer efficiency height, and is applied widely, safe and reliable, makes simple overhead condenser.
For addressing the above problem, the utility model by the following technical solutions:
Overhead condenser, comprise tower body, the two ends up and down of described tower body are respectively equipped with upper cover and low head, tubulation by some sealings between described upper cover and the low head is communicated with, described upper cover is provided with steam inlet, the bottom of described low head is provided with condensation-water drain, it is characterized in that: described tower body is made of last tower body and following tower body, and described going up between tower body and the following tower body is provided with U type bellows expansion joint.
Below be to further improvement in the technical proposal:
Described going up is provided with the last grid spacer that tubulation can be located in the tower body, following tower body is provided with down grid spacer, and last grid spacer and following grid spacer are semicircle, have reduced the turbulent flow between last grid spacer and the following grid spacer, have reduced the load of vavuum pump.
The described grid spacer that goes up is oppositely arranged on tower body with following grid spacer, reduced existing the turbulent flow dead angle between dividing plate, thereby material is difficult in this fouling.
Described position of going up close upper cover on the tower body is provided with coolant outlet and exhaust outlet, position near low head on the following tower body is provided with cooling water inlet and discharge outlet, cooling water is taked from the mode of afterbody charging, and cooling water flows along tubulation and reduced flow velocity, has increased heat exchange.
Use technique scheme, the beneficial effects of the utility model, be provided with bellows expansion joint between last tower body and the following tower body, prevented that the shell journey coefficient of expansion difference from causing heat exchanger to be subjected to stress fail in tension, the position near low head on the following tower body is provided with cooling water inlet, and cooling water is taked from the mode of afterbody charging, cooling water flows along tubulation and has reduced flow velocity, increased heat exchange, it is low to have reduced manufacturing expense, has reduced the weight of equipment under the situation of equal heat exchange efficiency.
Come the technical solution of the utility model is further described below in conjunction with drawings and Examples:
