In order to ensure production safety, large industrial enterprises can use air compressors with various heat dissipation forms, and meanwhile, compressed air for production needs to be filtered and dehumidified at low temperature, so that the production process requirements are met, the operation of the air compressors is discontinuous and does not operate continuously, when the pressure of a pressure tank reaches a pressure value, equipment is shut down, and discontinuous waste heat cannot be applied and used for supplying heat.
Disclosure of Invention
The invention aims at the discontinuous operation of the air compressors and the waste heat recovery of the combined use of a plurality of air compressors, and simultaneously carries out auxiliary dehumidification on the compressed air, thereby achieving the waste heat recovery of the air cooling air compressor, the liquid cooling air compressor and the compressed air tank, and the recovered waste heat is used for preparing hot water for production and life and heating water in winter.
The system is realized by an air-cooled air compressor machine room (the machine room comprises an air-cooled air compressor unit, an air source heat pump and a ventilation duct), a liquid-cooled air compressor unit, a cooling tower, a compressed air tank (the compressed air tank comprises a tank cavity, a cooling pipe, an antifreezing solution cavity, a drain valve, a water collecting box, a gas conveying pipe and an antifreezing solution pressure gauge), a water source heat pump, a valve group, a water collecting and distributing node, a process controller and a heat exchanger (used for oil cooling or non-water liquid isolated heat exchange); each air cooling air compressor and each liquid cooling air compressor need independently set up operating pressure, and the high temperature of water source heat pump and air source heat pump preparation is collected through water collecting and distributing node, and the high-pressure air that air cooling air compressor and liquid cooling air compressor prepared collects in the compressed air jar through the gas transmission pipeline.
The air cooling air compressor machine room seals most ventilation ducts in winter to store heat, utilizes the air source heat pump to recover the heat released by the air cooling air compressor, opens the ventilation ducts in a proper amount when the indoor temperature exceeds 40 ℃ in winter, quickly cools, closes most ventilation ducts when the indoor temperature is lower than 35 ℃, keeps the indoor temperature, opens all ventilation ducts in summer, and cools through natural temperature.
The compressed air tank is a double-layer tank body, the outer layer of the double-layer tank body is an antifreezing solution cavity, an antifreezing solution is simultaneously injected into the antifreezing solution cavity through a cooling pipe, a pressure gauge is arranged for observing the pressure of the antifreezing solution, the water source heat pump absorbs the temperature of air in the compressed air tank to reduce the temperature to 7 ℃ so as to enable the temperature to be close to a condensation point, the operation load of the heat pump is reduced while recovering compressed air, the condensation point of the compressed air is 2-5 ℃, the temperature is absorbed to 7 ℃, the operation load of a compressed air dehumidifier is reduced, and when the temperature in the air tank is lower than 7 ℃, a valve group of the compressed air tank is cut off.
The anti-freezing liquid in the anti-freezing liquid cavity of the compressed air tank is in a normal pressure state, so that the water pressure is lower than the pressure of the compressed air in the compressed air tank, the leakage problem cannot occur, and when the tank body is broken, the compressed air can ensure that the anti-freezing liquid cannot flow into the tank cavity.
Every two air-cooled air compressors and every two liquid-cooled air compressors are in one group, and a first group of air-cooled air compressors and a second group of liquid-cooled air compressors and a third group of liquid-cooled air compressors are respectively provided with working pressure of 0.5MPa-0.6MPa, 0.6MPa-0.7MPa and 0.7MPa-0.9MPa, so that the air compressors work step by step according to the pressure in the compressed air tank and continuously run, the shutdown caused by full air storage of the compressed air tank is avoided, and the stable operation of the waste heat recovery equipment is realized.
When monitoring that a high gas consumption process is to be carried out, the process controller transmits signals to the air cooling air compressor and the liquid cooling air compressor in advance, removes pressure limitation, carries out full-load operation, and restores the pressure limitation of the air cooling air compressor and the liquid cooling air compressor in advance before the high gas consumption process is finished, so that the phenomenon that the air compressor is stopped due to the fact that a compressed air tank is fully stored due to the full-load operation of the air compressor is avoided.
The heat source of the water source heat pump is cooling circulating liquid of the liquid cooling air compressor and the compressed air tank, waste heat is recovered after the cooling circulating liquid is collected through the water collecting node and is used as source water supply, cooled source return water is respectively sent back to the compressed air tank and the liquid cooling air compressor through the water distributing node, hot water prepared by high-temperature water supply and the air source heat pump is collected through the water collecting node and is used for heat supply, and return water after heat supply respectively returns to the air source heat pump and the water source heat pump through the water distributing node to be heated again, so that.
When the high gas consumption process is started, the recovery temperature of the water source heat pump is increased, when the waste heat is too large, the operation power of the air source heat pump is reduced, the ventilation duct is opened, and the air cooling air compressor is naturally used for heat dissipation.
The invention has the beneficial effects that:
1. the possibility of stopping the air compressor is reduced by adjusting the working pressure of the air-cooled air compressor and the working pressure of the liquid-cooled air compressor under different conditions.
2. The condition that air pressure and air quantity are insufficient is effectively avoided by monitoring the production process, and meanwhile, when the high-air-consumption process is stopped, the pressure control of the air compressor is restored in advance, so that the running time of the air compressor is prolonged, and the air compressor is used as a second means for preventing the air compressor from stopping.
