Specific embodiment

The technical solution of the utility model is described further below in conjunction with the accompanying drawings, but claimed scope is not limited In described.

A kind of ammoniacal liquor heat exchanger as shown in Figure 1, Figure 2, Figure 3, Figure 4, including gripper shoe 1 and in gripper shoe 1 Cold flow pipe 7, pipe joint A2, pipe joint B3, is provided with hot-fluid pipe 5 in the cold flow pipe 7, the hot-fluid pipe 5 is fixed on support On plate 1, isolated tube 6, the pipe joint B3 and hot-fluid pipe 5 and the shape of isolated tube 6 are provided between the cold flow pipe 7 and hot-fluid pipe 5 Into separate cavities connection, the pipe joint A2 and the inner space of hot-fluid pipe 5.

Gripper shoe 1 is used to support cold flow pipe 7, pipe joint A2, pipe joint B3, cold flow pipe 7 to be used to be passed through cryogen, in order to It is easy to heat cryogen, hot-fluid pipe 5 is provided with cold flow pipe 7, hot-fluid pipe 5 is used to be passed through high temperature fluid, according to heat biography The rule passed, the heat in high temperature fluid is gradually transferred in cryogen.

Domestic water is heated using coking distilled ammonia wastewater, coking distilled ammonia wastewater should be prevented effectively from and mixed to domestic water In, therefore isolated tube 6 is provided between cold flow pipe 7 and hot-fluid pipe 5, the separate cavities that hot-fluid pipe 5 and isolated tube 6 are formed work as heat When flow tube 5 is leaked, coking distilled ammonia wastewater is initially entered in separate cavities, so as to be prevented effectively from in the pipe of cold flow pipe 7.In order to It is easy to observe and discharge the coking distilled ammonia wastewater of leakage, the separate cavities that pipe joint B3 is formed with hot-fluid pipe 5 and isolated tube 6 are connected, Pipe joint B3 is arranged in gripper shoe 1.

For the ease of heat exchange, heat exchanger fin B61 is provided with the inwall of isolated tube 6, heat exchanger fin B61 increases isolated tube Contact area between 6 and separate cavities, so as to improve heat exchange efficiency, is accordingly provided with heat exchanger fin on the lateral wall of hot-fluid pipe 5 Contact area between A51, heat exchanger fin A51 increase hot-fluid pipe 5 and separate cavities, so as to improve heat exchange efficiency.

For the ease of cryogen is mirrored in cold flow pipe 7, pipe joint C4 is provided with cold flow pipe 7.

When using the technical program, first water is full of in the separate cavities that hot-fluid pipe 5 and isolated tube 6 are formed, then by Jiao Change the hot fluids such as distilled ammonia wastewater to be introduced in hot-fluid pipe 5, the heated cold flow body such as domestic water is introduced in cold flow pipe 7.
