The shell and tube type condenser provided by the utility model is high in the heat exchange efficiency and good in the condensation effect; condensed liquid ammonia water and ammonia-containing gas which is not condensed are discharged from different outlets, so that different treatments can be conducted on the liquid ammonia water and the ammonia-containing gas in subsequent processes; the service life is long.

Description

A kind of ammonia still tower top shell and tube condenser
Technical field
The utility model relates to a kind of condensing unit, is specifically related to a kind of ammonia still condenser.
Background technology
Condenser is the important component part of ammonia Distillation recovery system.High-concentration ammonia nitrogenous wastewater carries out rectifying in ammonia still according to steam stripping principle, ammonia is overflowed from tower top with gas form.By condenser heat exchange effect, thereby can be used as product after being liquefied containing ammonia steam, reach the object of again being utilized.
Ammonia formation ammoniacal liquor soluble in water, and ammoniacal liquor has volatility simultaneously, therefore, to carrying out condensation containing ammonia gas, all contains ammonia in liquid phase and gas phase.And its shell side of traditional shell trumpet cooler or tube side are and singly enter singly to go out pattern, make to export existing ammoniacal liquor and form, exist again part to overflow containing ammonia gas, thereby cause condensation can only liquefy part containing ammonia gas, affect the recycled in its entirety effect of ammonia Distallation systm.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provide a kind of heat exchanger effectiveness high, condensation effect is good, the liquid ammoniacal liquor being condensed and flowing out by different outlets respectively containing ammonia gas of not being condensed, can in subsequent technique, to it, carry out respectively different disposal, the ammonia still tower top shell and tube condenser of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of ammonia still tower top shell and tube condenser described in the utility model, it comprises housing, in one end, described housing top, be provided with air inlet, on described housing top, the other end is provided with gas outlet, bottom at described housing gas outlet end is provided with liquid outlet, on the end face of described housing gas outlet end, be provided with cooling water inlet and coolant outlet, on the end face of described shell air inlet end, be provided with end socket, at described enclosure interior front end, be provided with anterior tube sheet, rear end is provided with rear portion tube sheet, between described anterior tube sheet and rear portion tube sheet, be provided with heat exchanger tube, between described cooling water inlet and coolant outlet, be provided with dividing plate, described heat exchanger tube is communicated with rear portion tube sheet, in described enclosure interior, be separately provided with deflection plate, described deflection plate is vertical with the axis of housing.
Described deflection plate is welded in described enclosure interior.
Described heat exchanger tube and rear portion Tube-sheet Welding are fixed.
In described lower housing portion, be provided with housings support frame.
Described heat exchanger tube is divided into top heat exchanger tube and bottom heat exchanger tube, and described top heat exchanger tube is communicated with cooling water inlet, and described bottom heat exchanger tube is communicated with coolant outlet.
Described top heat exchanger tube and bottom heat exchanger tube are all at least one.
Between described deflection plate and housing, be provided with airflow gap.
The utility model shell side medium is for containing ammonia gas, tube side medium is cooling water, described deflection plate can change gas flow and flow velocity in condensation process, improve heat exchanger effectiveness, and then lifting condensation effect, the ammoniacal liquor of condensation liquefaction flows out from liquid outlet, and what be not condensed can overflow from gas outlet containing ammonia gas.
The utility model flow of cooling water direction is, first by water inlet, enter in the one group of heat exchanger tube communicating with it, this group heat exchanger tube other end enters the space between tube sheet and end socket through anterior tube sheet, then through another group heat exchanger tube reverse flow, is finally communicated to delivery port and flows out.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, adopt top heat exchanger tube and bottom heat exchanger tube, heat exchanger effectiveness is high, adopts deflection plate, can change gas flow and flow velocity in condensation process, improve heat exchanger effectiveness, and then lifting condensation effect, this long product lifecycle, realistic instructions for use.
