Description

Technical Field

[0001] The utility model relates to the technical field of high-nitrogen air separation, in particular to a convenient cold box for container transportation. Background Art

[0002] Traditional small air separation cold boxes are delivered to the site in parts. Even the distillation systems of some air separation equipment only have the aluminum unit equipment and box body manufactured in the factory. The assembly of the box body, equipment installation and pipeline connection between equipment need to be completed on the customer's site. This requires professionals to go to the customer's site to guide the installation according to the arrival of the goods. Outdoor installation is restricted by factors such as site conditions, personnel and weather, resulting in a long installation cycle and high installation costs. At the same time, there is often a problem of insufficient management on site, and parts are often lost or cannot be found, which will cause great trouble to the on-site installation and even cause delays in the construction period. Doing so will undoubtedly increase the cost. For this reason, the utility model discloses a convenient cold box for container transportation to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0005] A portable cold box for container transportation includes a main cold box. The main cold box is provided with a tower, a main condenser evaporator and a plate heat exchanger from top to bottom. An expander is provided in the bottom space of the plate heat exchanger. The pipeline valves in the main cold box are concentrated in the bottom space of the plate heat exchanger, and the pipeline instruments of the main cold box are all connected to an instrument control box.

[0006] As a further solution of the present invention, the instrument and control box is equipped with a transmitter, and the instrument and control box and the transmitter are integrated on the front of the main cold box.

[0007] As a further solution of the present invention, the valve stems of the pipeline valves all extend to the outside of the main cold box.

[0008] As a further solution of the present invention, a bracket is provided in the main cold box, and an inspection staircase is fixed to the bracket.

[0009] As a further solution of the present invention, the bracket is fixed with multiple supporting beams, and the multiple supporting beams are respectively fixed to different positions of the tower.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This convenient cold box for container transportation can be assembled before leaving the factory and does not need to be disassembled on site. This greatly reduces the customer's on-site construction workload and greatly improves on-site installation efficiency. The three-month installation period can be shortened to one month. At the same time, the factory guarantees the conditions for cold box assembly, construction and supervision, which can better and more strictly control the engineering quality of the cold box.

[0012] 2. The utility model is a portable cold box for container transportation. The main condenser evaporator is widened and thickened, which reduces the height of the main condenser evaporator, thereby reducing the height of the tower. The cold box structure is compact and safe, with a shorter height, length and width. Therefore, the cold box for overseas projects can be transported by container, reducing transportation costs, shortening logistics cycles, and improving safety.

[0013] 3. This utility model is a portable cold box for container transportation. The pipe valves are concentrated in the bottom space of the plate heat exchanger for piping. This makes full use of this bottom space to achieve the purpose of reducing the overall footprint of the cold box. It greatly reduces the volume and floor space of the cold box and its supporting equipment. The integrated valves, instrumentation and control cabinet and transmitter make the operation interface simple and beautiful.

[0014] 4. The utility model is a convenient cold box for container transportation. It uses a bracket as an exoskeleton for support. The supporting beam can strengthen the firmness of the connection between the bracket and the tower. The whole can be loaded into the container for transportation, ensuring stability during transportation and realizing the convenience and integration of the cold box.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See also Figure 1-Figure 2The utility model provides a portable cold box for container transportation, comprising a main cold box 1, wherein the main cold box 1 is provided with a tower 2, a main condenser evaporator 3 and a plate heat exchanger 4 from top to bottom, and a bracket 11 is provided in the main cold box 1, and an inspection staircase is fixed to the bracket 11;

[0021] Specifically, the maintenance stairs are installed on the bracket 11, and it may be designed to be retractable or fixed to facilitate workers to climb to different working levels. The practicality and safety of on-site operations ensure that maintenance personnel can easily reach the equipment parts that need maintenance.

[0022] Furthermore, the bracket 11 is fixed with a plurality of support beams 12, and the plurality of support beams 12 are respectively fixed to different positions of the tower 2;

[0023] Specifically, the bracket 11 serves as an exoskeleton for support, and the support beam 12 strengthens the connection between the bracket 11 and the tower 2, thereby ensuring stability during transportation.

[0024] Furthermore, an expander 5 is provided in the bottom space of the plate heat exchanger 4, the pipeline valves 6 in the main cold box 1 are concentrated in the bottom space of the plate heat exchanger 4, and the pipeline instruments 7 of the main cold box 1 are all connected to the instrument control box 8;

[0025] Specifically, the space inside the cold box can be used more effectively, the occupied area can be reduced, and the overall structure can be made more compact. The centrally arranged pipeline valves 6 and pipeline instruments 7 are convenient for maintenance and inspection because they are easier to access, which can save maintenance time and reduce maintenance difficulty.

[0026] Furthermore, the instrument control box 8 is equipped with a transmitter 9, and the instrument control box 8 and the transmitter 9 are integrated on the front of the main cold box 1;

[0027] Specifically, the operator can easily access the control system, which improves the convenience of operation. The operating data of the cold box (such as temperature, pressure, flow, etc.) can be displayed in real time on the instrument and control box 8, which is convenient for the operator to monitor and analyze the operating status of the system. Integrating the instrument and control box 8 and the transmitter 9 can reduce the additional space occupied, making the overall design more compact and saving installation space. Through the integrated design, the external exposure of pipelines and cables can be reduced, and the safety risks caused by external damage are reduced, making the front of the main cold box 1 look more tidy and beautiful, and improving the overall appearance of the product. When the instrument and control box 8 or the transmitter 9 needs to be maintained or calibrated, the operator can operate directly on the front of the main cold box 1, which simplifies the maintenance process.

[0028] Furthermore, the valve stems of the pipeline valves 6 are extended to the outside of the main cold box 1;

[0029] Specifically, the valve stem is extended to the outside of the cold box, so that the operator can directly operate the valve without opening the cold box or entering the interior. This can improve the convenience and efficiency of operation, and enable the cold box to adapt to more working environments and usage conditions, whether it is space-constrained or there are special requirements for operational safety.

[0030] When in use, this convenient cold box for container transportation transfers most of the on-site work to the factory, which greatly improves various factors such as site conditions, equipment, personnel and weather, and ensures product quality, personnel safety and construction progress.
