Description

Technical Field

[0001] The utility model relates to auxiliary equipment for a regenerative zero-gas-consumption air-blast heat absorption dryer, in particular to a condenser for a zero-gas-consumption variable-frequency air-blast heat absorption dryer. Background Art

[0002] During the use of the existing regeneration zero-gas consumption blower hot adsorption dryer, after the adsorption tower completes the heating regeneration, it needs to be blown cold regeneration. In this process, the blower draws the dry hot air in the adsorption tower during the regeneration process into the main cooler for cooling, and then the blower cools the cooled air again through the auxiliary cooler to the optimal blowing cold temperature to cool the adsorbent in the adsorption tower during the regeneration process.

[0003] Most of the existing zero-gas-consumption variable-frequency air-blast heat absorption dryer condensers use conventional heat exchangers, which have relatively poor heat exchange effects. To ensure the cooling effect, the specifications of the main cooler are generally relatively large; and the heat exchange efficiency of the existing main cooler is generally relatively stable. Since the dry hot air in the adsorption tower has a temperature drop trend during the cold regeneration process, the operation adaptability of the main cooler is relatively poor. During the cooling process, since the cooling efficiency cannot be adjusted adaptively, there are often problems such as insufficient cooling or excessive cooling energy consumption, which is very troublesome.

[0004] Therefore, on the basis of effectively improving the heat exchange effect of the main cooler, the purpose of the present invention is to design a condenser for a zero-gas-consumption variable-frequency blower heat desiccant machine that can effectively form a sufficient cooling effect when the temperature is high and an energy-saving cooling effect when the temperature is low, thereby reducing energy consumption while effectively maintaining the cooling and heat exchange effect. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the utility model provides a condenser for a zero-gas-consumption variable-frequency air-blast heat absorption dryer, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A condenser for a zero-gas-consumption variable-frequency air-blast heat absorption dryer, comprising:

[0008] A cooler shell, wherein a corresponding fixed baffle is fixedly mounted on one side of the cooler shell, and a corresponding movable baffle is movably mounted on the other side of the cooler shell, and an elastic barrel is sealedly connected between the peripheries of the fixed baffle and the movable baffle;

[0009] A plurality of heat exchange ventilation pipes are installed between the fixed partition and the movable partition in a sealed manner. The heat exchange ventilation pipe is composed of two rigid parts with a corrugated pipe part connected in the middle.

[0010] The refrigerant circulation mechanism includes a refrigerant inlet pipe and a refrigerant outlet pipe installed on the cooler shell, the refrigerant inlet pipe and the refrigerant outlet pipe are respectively connected to the elastic barrel body, and corresponding flow regulating valves are fixedly installed on the refrigerant inlet pipe and the refrigerant outlet pipe.

[0011] A group of refrigerant inlet coils and refrigerant output coils located outside the fixed partition and the movable partition are arranged in the cooler shell, and a plurality of refrigerant flow pipes that penetrate the heat exchange ventilation pipe are connected between the refrigerant inlet coils and the refrigerant output coils, and the outer side surfaces of the refrigerant flow pipes are spaced apart from the inner side walls of the heat exchange ventilation pipe.

[0012] The refrigerant inlet pipe and the refrigerant outlet pipe are respectively made of flexible pipes.

[0013] The refrigerant inlet coil, the refrigerant outlet coil, and the refrigerant flow pipe are respectively made of metal pipes.

[0014] The elastic barrel body is made of a flexible rubber material and is fixed between the peripheries of the fixed partition and the movable partition by gluing.

[0015] The outer side wall of the elastic barrel body abuts against the inner side wall of the cooler shell.

[0016] The outer side of the fixed partition is integrally formed with a corresponding mounting flange facing outward, and the mounting flange is fixed to the inner side wall of the cooler shell by bolt locking.

[0017] The cooler shell includes a cylindrical basic shell, both sides of the basic shell are respectively connected outwardly with truncated cone-shaped air guides, and the side of the air guide that is not connected to the basic shell is respectively provided with corresponding air guide pipes.

[0018] Advantages of the utility model:

[0019] 1) The utility model includes a cooler shell, and a fixed partition and a movable partition arranged in the cooler shell. An elastic barrel is arranged between the outer periphery of the fixed partition and the movable partition, and a heat exchange ventilation pipe with a retractable length is installed between the fixed partition and the movable partition. In this way, the heat exchange stroke can be adjusted without affecting the normal ventilation and heat exchange; in the early stage of cold regeneration, the temperature is relatively high. At this time, the inlet flow of the refrigerant into the pipe can be increased to form a boost pressure, thereby expanding the distance between the fixed partition and the movable partition to extend the heat exchange stroke, thereby ensuring the cooling effect; in the later stage of cold regeneration, as the temperature decreases, the inlet flow of the refrigerant into the pipe can be reduced to form a pressure relief, thereby shortening the heat exchange stroke, and forming energy-saving cooling when the temperature is low. Thereby, while reducing energy consumption, the cooling and heat exchange effect is effectively maintained.

[0020] 2) The cooler shell of the utility model is also provided with a refrigerant inlet coil and a refrigerant outlet coil, and the refrigerant inlet coil and the refrigerant outlet coil are connected with a plurality of refrigerant flow pipes penetrating the heat exchange ventilation pipe, and the outer side of the refrigerant flow pipe is arranged at intervals with the inner side wall of the heat exchange ventilation pipe. Thus, the airflow to be heat exchanged flowing through the heat exchange ventilation pipe can be distributed in a ring shape through the interval between the refrigerant flow pipe and the heat exchange ventilation pipe, so as to reduce the distance between the airflow to be heat exchanged and the heat exchange surface, thereby significantly improving the heat exchange effect.

[0021] 3) In the early stage of cold blowing regeneration, the refrigerant is circulated between the refrigerant entering the coil and the refrigerant output coil to further ensure the cooling effect; in the later stage of cold blowing regeneration, the refrigerant is no longer circulated between the refrigerant entering the coil and the refrigerant output coil to further form energy-saving cooling when the temperature is low. At this time, the refrigerant flow pipe is used as a diversion component of the air flow to be heat exchanged, which can help improve the heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model comprises a cooler shell 1, and a fixed partition 2 and a movable partition 3 arranged in the cooler shell 1. An elastic barrel 4 is arranged between the outer peripheries of the fixed partition 2 and the movable partition 3, and a heat exchange ventilation pipe 5 with a retractable length is installed between the fixed partition 2 and the movable partition 3. In this way, the heat exchange stroke can be adjusted without affecting the normal ventilation and heat exchange; in the early stage of cold regeneration, the temperature is relatively high. At this time, the inlet flow of the refrigerant inlet pipe 601 can be increased to form a pressurization, thereby expanding the distance between the fixed partition 2 and the movable partition 3 to extend the heat exchange stroke, thereby ensuring the cooling effect; in the late stage of cold regeneration, as the temperature decreases, the inlet flow of the refrigerant inlet pipe 601 can be reduced to form a pressure relief, thereby shortening the heat exchange stroke, and forming energy-saving cooling when the temperature is low.

At this time, the refrigerant flow tube 9 is used as a diversion component of the air flow to be heat exchanged, which can assist in improving the heat exchange effect.

[0034] The refrigerant inlet pipe 601 and the refrigerant outlet pipe 602 are made of flexible pipes. The refrigerant inlet coil 7, the refrigerant outlet coil 8, and the refrigerant flow pipe 9 are made of metal pipes.
