Description

Semi-tube type heat exchanger

Technical Field

The utility model relates to a heat exchanger, in particular to a half-tube heat exchanger.

Background

In the prior tube type silicon carbide heat exchanger for corroding media, the heat exchange tube material adopts silicon carbide material to prevent the corrosion of the media, and in the heat exchanger structure in industry, the arrangement mode of the heat exchange tubes in the shell is designed according to the maximum area in the shell, so as to increase the heat exchange area in the effective sectional area; however, the disadvantage is that the heat exchange medium cannot be fully mixed under the condition of the same heat exchange area, so that uneven heating is caused.

Disclosure of Invention

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a half-tube heat exchanger, includes the casing and installs the head at the casing both ends, the junction between casing and the head is equipped with the steel lining board, horizontal distribution has the heat exchange tube in the casing, the tip of heat exchange tube respectively with corresponding steel lining board sealing connection, the casing is tubular structure, a plurality of the heat exchange tube horizontal installation is in two between the steel lining board, the axis of the heat exchange tube of the top one row all is located the horizontal plane at axis place of casing.

Preferably, the heat exchange tube is made of silicon carbide material.

Preferably, a positioning hole is formed in the end face of the steel lining pipe plate, the end portion of the heat exchange pipe is detachably connected with the positioning hole, and a sealing ring is arranged on the inner wall of the positioning hole.

Preferably, the head is made of stainless steel material.

Advantageous effects

The utility model provides a half-tube heat exchanger, which is characterized in that a replacement heat pipe is not arranged in the upper half area of the inside of a shell by changing the distribution mode of the traditional heat exchange tubes, so that the effective longitudinal sectional area of the shell is increased, the media can be fully mixed, and the heat replacement is uniform; the heat exchange tube is a silicon carbide heat exchange tube and has higher acid and alkali resistance; the seal head is made of stainless steel materials, so that the problem of short service life caused by corrosion easily generated by carbon steel in the past is solved.

Through the arrangement, the heat exchange efficiency of the heat exchanger is improved, the service life of the heat exchanger is prolonged, and the heat exchanger has practical value.
