Abstract
The invention relates to a screw air compressor waste heat recovery device, which comprises a motor, a screw main engine, an oil tank, an oil-air separator, a heat exchanger, an oil filter, an air filter, an insulation water tank and a cold water tank. Oil precipitated in the oil tank sequentially passes through the heat exchanger and the oil filter so as to return to the screw main engine; an oil inlet and an oil outlet of the heat exchanger are connected with a temperature control valve; oil separated by the oil-air separator flows to the screw main engine through an oil return check valve; air separated by the oil-air separator is connected with an air drier and an air storage tank through the heat exchanger; a water outlet of the insulation water tank is connected with a water pump through a warm water valve; and a water level detector, a temperature detector and a drain valve are arranged in the insulation water tank. The screw air compressor waste heat recovery device provided by the invention adopts oil-air double-circuit heat exchange, and maximally collects heat energy generated during the operation of an air compressor, the water level detector in the insulation water tank monitors a water level in the insulation water tank, and when the water level reaches a preset value, a cold water valve is closed, and the warm water valve is opened, so that water in the insulation water tank can be heat circularly.
Description
Technical field
The present invention relates to a kind of waste-heat recovery device, especially a kind of screw air compressor waste-heat recovery device.
Background technology
The heat that air compressor machine is produced when working（Mainly frictional heat）By the oil circulating system of its own, high temperature oil is transported to oil cooler, oil cooler is usually shell-and-tube or air-cooled heat exchanger, and wherein shell-and-tube heat exchanger is cooled down lubricating oil by specific cooling water, and cooling water transfers heat to outdoor air by cooling tower again.In addition, the compressed air that air compressor is produced is also high temperature, it is necessary to also to be used for using by cylinder could be entered after a cooling device.Two parts heat is added up and is approximately equal to the 3/4 of compressor power input, and recuperable space is very big.The screw air compressor waste-heat recovery device that generally uses is excessively complicated at present, or in heat recovery it is not abundant enough.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of screw air compressor waste-heat recovery device, and the heat energy produced in compressor operation, attemperater water level, temperature-controllable are collected in the heat exchange of oil gas two-way to greatest extent.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of screw air compressor waste-heat recovery device, including motor, screw host, oil tank, gs-oil separator, heat exchanger, oil strainer, air cleaner, attemperater, motor drives screw host to rotate, air enters screw host by air cleaner, screw host connects oil tank, oil tank connects gs-oil separator, heat exchanger absorbs the water in the heat attemperater of high temperature oil/gas, the oil precipitated in oil tank sequentially passes through heat exchanger, oil strainer, return to screw host, heat exchanger oil inlet and oil-out connection temperature-sensing valve, the oil that gs-oil separator is isolated flows to screw host by oil return check valve, the air that gs-oil separator is isolated connects air dryer by heat exchanger, air accumulator.
Preferably, the present apparatus also includes cold water storage cistern, and cold water storage cistern is connected to the water inlet of heat exchanger by cold valves, water pump.
Preferably, the delivery port of heat exchanger is connected to the water inlet of attemperater by temperature sensor and flow control valve, and the temperature of the entrance attemperater water that flow control valve is detected according to temperature sensor controls to enter the water-carrying capacity of attemperater.
Preferably, attemperater delivery ports are connected by warm water valve with water pump.
Preferably, level switch, temperature detector and draining valve are set in attemperater.
The present invention is using the heat exchange of oil gas two-way, the heat energy produced in compressor operation is collected to greatest extent, level switch in attemperater is monitored to the water level in attemperater, when water level reaches preset value, then close cold valves, open warm water valve so that the water in attemperater can be with circulating-heating.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
A kind of screw air compressor waste-heat recovery device, as shown in Figure 1, including motor, screw host, oil tank, gs-oil separator, heat exchanger, oil strainer, air cleaner, attemperater, motor drives screw host to rotate, air enters screw host by air cleaner, screw host connects oil tank, oil tank connects gs-oil separator, heat exchanger absorbs the water in the heat attemperater of high temperature oil/gas, the oil precipitated in oil tank sequentially passes through heat exchanger, oil strainer, return to screw host, heat exchanger oil inlet and oil-out connection temperature-sensing valve, the oil that gs-oil separator is isolated flows to screw host by oil return check valve, the air that gs-oil separator is isolated connects air dryer by heat exchanger, air accumulator；Temperature-sensing valve control between heat exchanger oil inlet and oil-out is back to the oil temperature of screw host, and oil return check valve prevents the oil that gs-oil separator is isolated from flowing backward to gs-oil separator.
Present invention additionally comprises cold water storage cistern, cold water storage cistern is connected to the water inlet of heat exchanger by cold valves, water pump, cold valves are opened, water in cold water storage cistern is by water pump inflow heat exchanger, after heat exchange being carried out in heat exchanger, water is flowed out from the delivery port of heat exchanger, and attemperater is flowed into by temperature sensor and flow control valve.The temperature of the entrance attemperater water that flow control valve is detected according to temperature sensor come control enter attemperater water-carrying capacity.If the water temperature in attemperater is higher than required temperature, reduce the flow of inlet water of attemperater；If the water temperature in attemperater is less than required temperature, the flow of inlet water of attemperater is tuned up.
Attemperater delivery ports are connected by warm water valve with water pump, and level switch, temperature detector and draining valve are set in attemperater.Level switch is monitored to the water level in attemperater, when water level reaches preset value, then closes cold valves, opens warm water valve and water pump, and water pump pressurizes and causes that the water in attemperater can carry out heat exchange with inflow heat exchanger, and the water of attemperater constantly heats up；Water temperature in temperature detector detection attemperater exceedes, then draining valve is opened in control, and by the warm water discharge in attemperater, transfer storage while opening cold valves, is closed warm water valve, continues heating of intaking.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and any change or replacement expected without creative work should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
