Description

Technical Field

[0001] The invention relates to the technical field of waste heat regeneration drying, and in particular to a waste heat regeneration dryer. Background Art

[0002] Waste heat regeneration dryer is a new type of adsorption dryer. It is neither a heat regeneration type nor a heatless regeneration type, but a temperature swing adsorption type. It uses the heat from the high-temperature exhaust gas of the air compressor to directly heat the regeneration desiccant, so that the adsorbent is completely regenerated.

[0003] The existing waste heat regeneration dryer is mainly composed of an air inlet pipe, a drying tower, a cooler, a separator, an air outlet pipe, a cold blow pipe, an exhaust pipe and a valve, etc. These components are interconnected through a complex pipe and valve system to form a closed-loop regeneration cycle system. However, the waste heat regenerator in the prior art is a process of drying and regenerating the adsorption material filled in the drying tower during the drying and regeneration process. Among them, the adsorption material generally uses a molecular sieve as a filler. However, the molecular sieve will produce a slight expansion after being saturated with water. When the molecular sieve expands, it will greatly reduce the gap in the drying tower. This will not only increase the resistance of the high-temperature gas discharged from the air compressor to pass through the drying tower and increase the power of the air compressor, but most of the adsorption materials in the drying tower are in a fixed state, which greatly affects the contact area between the high-temperature gas and the adsorption material, and the utilization rate of the adsorption material is low.‌ Summary of the invention

[0013] The working principle and beneficial effects of the present invention are: 1. In the present invention, when in use, the high-temperature exhaust end of the air compressor is connected with the air intake pipe. When the adsorption materials in the two regeneration cylinders are in a regenerated state, the hot gas valve, the cold gas valve, the air intake valve, the exhaust valve and the emergency valve at the corresponding positions are opened and closed, so that the high-temperature gas discharged from the air compressor directly enters the cooling machine and the condenser along the air intake pipe, the preheating pipe, the hot gas cavity in one of the regeneration cylinders, the gas transmission elbow, the emergency air guide pipe and the three-way pipe, and the high-temperature gas is cooled and dehumidified by the cooling machine and the condenser, so that the cooled gas enters the other regeneration cylinder along the cold gas pipe, and the cooled cold air passes through the air dispersion holes on the arc-shaped slag collecting plate along the bottom of the regeneration cylinder, enters the adsorption cylinder from the exhaust net, contacts with the adsorption material, and the moisture in the gas is adsorbed again by the adsorption material, and the gas is finally purified. The purified gas is discharged through the air intake hole, the air intake positioning pipe, the air transmission pipe, the exhaust pipe and the exhaust hood, and the discharged gas can be recycled. 2. In the present invention, after the adsorption material in one of the regeneration cylinders reaches saturation, when the saturated adsorption material is regenerated, the hot gas valve, cold gas valve, air intake valve, exhaust valve and emergency valve at the corresponding positions are opened and closed, so that the high-temperature gas discharged from the air compressor enters the regeneration cylinder where the saturated adsorption material is located along the air intake pipe and the preheating pipe, and the adsorption cylinder carrying the saturated material is preheated through heat exchange, and the gas entering the regeneration cylinder enters the conical material change cover through the gas delivery elbow and the gas delivery pipe. The high-temperature gas entering the conical material change cover flows from top to bottom in the adsorption cylinder toward the exhaust network through the air intake positioning pipe and the air intake through hole, so as to heat the adsorption material in the adsorption cylinder. High-temperature heating is performed to regenerate the adsorbent material. The water in the adsorbent material is evaporated by heating the adsorbent material internally and externally, and is discharged through the exhaust net along with the high-temperature gas. The discharged high-temperature and high-humidity gas then enters the air circulation pipe through the air dispersion hole, and then enters the cooler and condenser along the air circulation pipe, the hot air pipe, and the three-way pipe. The high-temperature gas is cooled and dehumidified by the cooler and condenser, and the cooled gas enters another regeneration cylinder along the cold air pipe. The gas is purified by the adsorbent material in the other regeneration cylinder, and the cycle is repeated. By alternately regenerating the adsorbent materials in the two regeneration cylinders, the exhaust gas from the air compressor has been treated. 3. In the present invention, when the gas discharged from the air compressor is regenerated and purified, the adsorption material itself will swell slightly during the process of gradual saturation of the adsorption material. When all the adsorption materials have expanded, the resistance of the high-temperature gas through the adsorption cylinder will increase. At this time, the power motor can be started, and the output end of the power motor drives the bevel gear 1 to rotate, the bevel gear 1 drives the bevel gear 2 to rotate, and the bevel gear 2 drives the adsorption cylinder connected thereto to rotate. Under the mutual engagement of multiple turning gears, the multiple adsorption cylinders in the regeneration cylinder rotate synchronously. When the adsorption cylinder rotates, the rotation direction of the spiral mixing blade is set to make the adsorption material in the adsorption cylinder move toward the top of the adsorption cylinder. While loosening the adsorption material, the contact surface between the adsorption material and the high-temperature gas can be replaced, thereby improving the utilization rate of the adsorption material.
