[0002] High-performance compression heat regeneration adsorption dryer is a device used for gas (such as air) drying treatment, commonly used in industrial applications such as pneumatic systems, chemical production, food processing, etc. Steam heating is an efficient and energy-saving heating method that can significantly improve the performance and efficiency of adsorption dryers.

[0003] Currently, there is a high-performance compression heat regeneration adsorption dryer with steam heating in the existing technology. The compression heat regeneration adsorption dryers commonly seen on the market are all of traditional structure. One is low-end compression heat without heater, and the other is compression heat that uses a heater to increase the regeneration gas temperature in situations where the dew point requirement is high. This type of equipment can obtain a better dew point, but the energy consumption is relatively high. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the compression heat regeneration adsorption dryers currently prevalent in the market in the prior art are all of traditional structure, one is low-end compression heat without heater, and the other is compression heat that uses a heater to increase the regeneration gas temperature in occasions with higher dew point requirements. This type of equipment can obtain a better dew point, but the energy consumption is relatively high. A high-performance compression heat regeneration adsorption dryer with steam heating is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-performance compression heat regeneration adsorption dryer with steam heating, comprising an air inlet pipe, a first double-way pipe is installed at one end of the air inlet pipe, a first control valve and a second control valve are installed on the outer walls of both ends of the first double-way pipe respectively, a steam heater is installed at one end of the first double-way pipe, a first after-cooling air distributor is installed at the other end of the first after-cooling air distributor, a second connecting pipe is installed at the other end of the first after-cooling air distributor, a first connecting pipe is installed between the steam heater and the second connecting pipe, a third control valve is installed on the outer wall of the second connecting pipe, a first three-way pipe is installed on the other end of the second connecting pipe, a fifth control valve and a sixth control valve are installed on the outer walls of both ends of the first three-way pipe respectively, a heating regeneration tower and an adsorption tower are fixed at both ends of the first three-way pipe respectively, a fourth three-way pipe is installed at one end of the heating regeneration tower and the adsorption tower, an outlet pipe is fixed on the outer wall of the fourth three-way pipe, and an eleventh control valve and a twelfth control valve are installed on the outer wall of the fourth three-way pipe on both sides of the outlet pipe respectively.

[0006] Preferably, a third three-way pipe is installed at one end of the heating regeneration tower, a ninth control valve and a tenth control valve are respectively installed on the outer walls at both ends of the third three-way pipe, and both ends of the third three-way pipe are connected to the fourth three-way pipe.

[0007] Preferably, a second double-way tube is installed on the outer wall of the second connecting tube, an auxiliary heater is provided in the second double-way tube, a fourth control valve is installed on the outer wall of the second double-way tube on one side of the auxiliary heater, and the third control valve is arranged between the two ends where the second double-way tube is connected to the second connecting tube.

[0008] Preferably, a second three-way pipe is installed in the first three-way pipe, a seventh control valve and an eighth control valve are respectively installed on the outer walls at both ends of the second three-way pipe, and the other end of the second three-way pipe is connected to the heating regeneration tower.

[0009] Preferably, a second after-cooling air separator is provided in the second three-way pipe located in the pipeline connected to the heating regeneration tower.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] In the utility model, the temperature of the gas is increased by a steam heater, which reduces energy consumption compared to the traditional method of using a heater to increase the intake temperature. At the same time, large air compression rooms generally have superheated steam generated by related processes, which is usually discharged and wasted. This device can make full use of this part of thermal energy. When the user's required low dew point is obtained, energy consumption is reduced. At the same time, the auxiliary heating tank plays an auxiliary role, preventing the steam heating temperature from being too low, and plays a double protection role. It is an important barrier for the good regeneration effect of the equipment. The design is scientific and reasonable. Compared with the conventional zero-gas consumption compression heat regeneration adsorption dryer with a heater, it can reduce energy consumption when the dew point can be output stably (can reach about -50). It can ensure the stable operation of the equipment, and at the same time, while meeting the dew point, the energy consumption is reduced, achieving multiple goals at one stroke, which is very important to users and has a wide range of applications. It can effectively meet the requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The effect achieved by the entire embodiment 1 is that compressed air enters through the air inlet pipe 1, the second control valve 4 is opened when the gas temperature is lower than the set value, otherwise it is closed, and it is heated by the steam heater 5, and then heated by the auxiliary heater 12. By opening the fourth control valve 11 and the fifth control valve 14, the steam enters the heating regeneration tower 16 for treatment. After the treatment, by opening the ninth control valve 23, the steam circulates and flows into the heating regeneration tower 16 again. By opening the eighth control valve 20, the steam passes through the second after-cooling gas separator 21 and enters the adsorption tower 17.

Both ends of the third three-way pipe 22 are connected with the fourth three-way pipe 25. A second two-way pipe 9 is installed on the outer wall of the second connecting pipe 8, and an auxiliary heater 12 is arranged in the second two-way pipe 9. A fourth control valve 11 is installed on the outer wall of the second two-way pipe 9 on one side of the auxiliary heater 12.

A three-stage separation method is adopted: cyclone separation + direct collision separation + stainless steel wire mesh demisting separation. First, droplets with larger particle sizes of more than 10μ㎡ are removed by cyclone separation and direct collision separation, and then mist particles as small as 5μ㎡ are removed by 150 mesh stainless steel wire mesh, and 99.9% of liquid water is separated from the cooled compressed air. The separation efficiency is higher than that of similar products, ensuring low dew point outlet air. Each pipeline of the device is equipped with a temperature detection device and a temperature probe, which monitors the temperature of the steam heating outlet to determine whether the auxiliary heating tank heating device discharges hot water according to the demand for hot water.

After the treatment, the ninth control valve 23 is opened to allow the steam to circulate and flow into the heating regeneration tower 16 again. The eighth control valve 20 is opened to allow the steam to enter the adsorption tower 17 after being treated by the second after-cooling gas separator 21. The tenth control valve 27 is opened to allow the treated steam in the adsorption tower 17 to be discharged from the outlet pipe 28.
