Description

Technical Field

[0001] This utility model relates to the field of condensation device technology, and in particular to a condensation collection device for the production of high-purity electronic chemicals. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid and transfer heat from the tubes to the air near the tubes in a rapid manner.

[0003] In the current technology, the heat exchange tubes in common heat exchangers are made of stainless steel and the heat exchanger is connected by a welded structure between the body and the partition. High-purity materials are not used and the contamination caused by the weld joints cannot be avoided. The collected products will come into contact with the heat exchanger shell and cause contamination, making it difficult to use for the condensation collection of high-purity products. Utility Model Content

[0004] The purpose of this invention is to provide a condensation collection device for the production of high-purity electronic chemicals, which solves the problem of collection pollution caused by the welded connection structure between the heat exchange tube body and the partition plate in traditional heat exchangers made of stainless steel.

[0005] To achieve the above objectives, this utility model provides a condensation collection device for the production of high-purity electronic chemicals, including a condenser body, which is divided into an upper condenser part and a lower condenser part. The upper condenser part and the lower condenser part are separated by a stainless steel partition. Multiple PFA tubes are connected to the upper condenser part, the lower condenser part and the product collection tank through a fixing assembly, and extend a certain length in the upper condenser part. The upper part of the condenser is connected to a product gas inlet and a waste recovery outlet, and the lower part of the condenser is connected to a condensate outlet and a condensate inlet. The fixing component includes a base, a locking block, a first locking plate, a second locking plate, and a tensioning member. The base is detachably connected to the stainless steel partition and slidably connected to the PFA tube. The locking block is integrally and symmetrically arranged on the base. The first locking plate is slidably connected to the PFA tube and the locking block respectively, and slidably inserted into the second locking plate. The second locking plate is slidably engaged with the PFA tube. The tensioning member is located on the top of the locking block.

[0006] The condenser body is made of 316L stainless steel, and the inner surface is polished to EP grade.

[0007] Wherein, when the PFA tube extends a certain length in the upper part of the condenser, its top port will be higher than the waste recycling port.

[0008] The tensioning component includes a first pull rod and a second pull rod. The first pull rod and the second pull rod are slidably connected to the locking block, the first card plate and the second card plate respectively, and are disposed through the block and threadedly connected to the base.

[0009] The first and second pull rods are both T-shaped structures, and each consists of a head, a smooth rod, and a stepped external thread.

[0010] This utility model discloses a condensation collection device for the production of high-purity electronic chemicals. By employing a PFA tube connected to the upper and lower parts of the condenser and the product collection tank via a through-plate structure, it solves the contamination problem caused by welded connections. The PFA tube extends a certain length from the upper part of the condenser, collecting only the liquid product condensed on it. This portion of the product then travels through the PFA tube to the product collection tank, resolving contamination issues caused by direct contact between the tube opening and the condenser body, as well as contamination caused by direct contact between the liquid product and the condenser body. Furthermore, the structure connecting the upper part of the condenser to a waste recovery port solves the problem of recycling unqualified liquid products that come into contact with the condenser body. This also addresses the contamination problem caused by the welded connection between the stainless steel heat exchange tube and the partition plate in traditional heat exchangers.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] like Figures 1 to 5 As shown, where Figure 1 This is a schematic diagram of the overall structure of a condensation and collection device used in the production of high-purity electronic chemicals. Figure 2 This is a structural diagram of a stainless steel partition. Figure 3 This is a structural diagram of the base. Figure 4 This is a structural diagram of the first card plate. Figure 5 This is a schematic diagram of the second clamping plate. This utility model provides a condensation collection device for the production of high-purity electronic chemicals: it includes a condenser body 100 and a fixing assembly. The fixing assembly includes a base 110, a locking block 111, a first clamping plate 112, a second clamping plate 113, and a tensioning component. The tensioning component includes a first pull rod 114 and a second pull rod 115. The aforementioned solution solves the problem of collection contamination caused by the welded connection structure between the stainless steel heat exchanger tube and the partition plate in traditional heat exchangers. It is understood that the aforementioned solution can reduce collection contamination.

[0020] In this embodiment, the condenser body 100 is directly used for condensing gaseous products.

[0021] The condenser body 100 is divided into an upper condenser 101 and a lower condenser 102, which are separated by a stainless steel partition 103. Multiple PFA tubes 104 are connected to the upper condenser 101, lower condenser 102, and product collection tank 105 via a fixing assembly, extending a certain length from the upper condenser 101. The stainless steel partition 103 has corresponding through holes and annular non-through threaded holes for easy installation of the base 110. The PFA tubes 104 have a U-shaped structure. The frame of the product collection tank 105 can be bolted to a position below the lower condenser 102. T-shaped sealing sleeves are installed on both the lower condenser 102 and the product collection tank 105. The inner cavity of the sealing sleeve has an installation groove and an O-shaped sealing ring is installed. The sealing ring slides and seals the PFA tubes 104, facilitating installation.

[0022] The upper part 101 of the condenser is connected to a product gas inlet 106 and a waste recovery port 107, and the lower part 102 of the condenser is connected to a condensate outlet 108 and a condensate inlet 109. The portion that does not condense at the opening of the PFA pipe 104 will condense onto the stainless steel partition 103 of the upper part 101 of the condenser, and finally be recovered to the raw material end for recycling through the waste recovery port 107.

[0023] The base 110 is detachably connected to the stainless steel partition 103 and slidably connected to the PFA tube 104. The locking block 111 is integrally and symmetrically arranged on the base 110. The first locking plate 112 is slidably connected to the PFA tube 104 and the locking block 111 respectively, and is slidably inserted into the second locking plate 113. The second locking plate 113 is slidably engaged with the PFA tube 104. The tensioning member is located on the top of the locking block 111. The base 110 is fixed by multiple countersunk bolts. A sealing gasket is provided at the contact point between its disc and the stainless steel partition 103 for sealing. At the same time, an annular mounting groove is provided in its inner cavity, and an O-ring is installed to cooperate with the PFA tube 104 for sealing. The locking block 111 is provided with an arc-shaped groove for sliding installation and limiting of the first locking plate 112. A rectangular groove is provided on the front end of the first locking plate 112 to facilitate the sliding insertion of the positioning rectangular block on the second locking plate 113. The locking block 111, the first locking plate 112, and the second locking plate 113 are each provided with vertically aligned through holes. The bottom of the through holes is aligned with the threaded holes on the base 110.

[0024] Secondly, the condenser body 100 is made of 316L stainless steel, with the inner surface polished to EP grade. The stainless steel partition 103 is made of the same material as the condenser body 100.

[0025] Then, when the PFA tube 104 extends a certain length into the upper part 101 of the condenser, its top port will be higher than the waste collection port 107. This structure will prevent the portion of the PFA tube 104 that has not condensed onto the stainless steel baffle 103 of the upper part 101 of the condenser from directly entering the product collection tank 105 from the port of the PFA tube 104.

[0026] Furthermore, the first pull rod 114 and the second pull rod 115 are slidably connected to the locking block 111, the first locking plate 112, and the second locking plate 113, respectively, and are threadedly connected to the base 110. The first pull rod 114 and the second pull rod 115 are used to maintain the assembly position of the first locking plate 112 and the second locking plate 113, thereby ensuring that the limiting plate of the PFA tube 104 is stably limited, preventing it from moving and ensuring a good seal.

[0027] Finally, both the first pull rod 114 and the second pull rod 115 are T-shaped structures, each consisting of a head, a smooth rod portion, and a stepped external thread portion. The smooth rod portion of this structure allows the first pull rod 114 and the second pull rod 115 to be slidably installed, the head is easily installed or removed by rotating it with an Allen wrench, and the stepped external thread end is easily connected to the base 110.

[0028] When using this invention to reduce collection contamination, the gaseous product enters the condenser body 100 from the gaseous product inlet 106. The portion condensed at the opening of the PFA pipe 104 then enters the product collection tank 105 along the PFA pipe 104. The product collection tank 105 is lined with high-purity PFA material to ensure product cleanliness. The portion not condensed at the opening of the PFA pipe 104 condenses onto the stainless steel partition 103 of the upper part 101 of the condenser and is finally recycled back to the raw material end through the waste recovery port 107. This application solves the contamination problem caused by welding by using a through-plate structure to connect the upper part 101 and the lower part 102 of the condenser and the product collection tank 105 via the PFA pipe 104. By extending the PFA pipe 104 a certain length from the upper part 101 of the condenser, only the PFA condensed at the opening is collected. The liquid product on pipe 104 will reach the product collection tank 105 through the PFA pipe 104, which solves the problem of contamination caused by direct contact between the pipe opening and the condenser body 100, as well as the problem of contamination caused by direct contact between the liquid product and the condenser body 100. By adopting the structure of connecting the upper part 101 of the condenser to the waste recovery port 107, the problem of recycling and reusing unqualified liquid products in contact with the condenser body 100 is solved. In addition, the problem of collection contamination caused by the welded connection structure between the heat exchange tube body and the partition plate in traditional heat exchangers is solved.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
