In addition, in order to ensure reliable operation of the methanol engine, the methanol supplied to the engine has requirements for cleanliness and temperature. However, at present, a special device for simultaneously realizing the methanol filtration and the temperature control is not available.
Based on the above problems, the application discloses a methanol filtering temperature control module of a methanol engine, which integrates a methanol filter 2 for filtering methanol and a heat exchanger for heating the methanol, thereby forming a special device for heating and filtering the methanol.
As shown in fig. 1 and 2, the methanol filter temperature control module of the methanol engine disclosed in the present application includes: mount 1, methanol filter 2, heat exchanger 3 and control by temperature change module 4.
Wherein, the methanol filter 2, the heat exchanger 3 and the temperature control module 4 are integrated on the mounting seat 1 to form a whole module structure and are integrally mounted on the methanol engine.

The inlet of the methanol filter 2 is communicated with the above-mentioned methanol inlet 11, and the methanol entering the methanol filter 2 through the methanol inlet 11 is filtered so that the methanol reaches a predetermined cleanliness.
The structure of the methanol filter 2 comprises a shell and a filtering membrane wire arranged in the shell, the entering methanol is filtered through the filtering membrane wire, and the filtered pure methanol is discharged out of the methanol filter 2. The structure and filtering principle of the methanol filter 2 can be referred to a known methanol filtering apparatus, and are not particularly limited herein.
The liquid inlet of the heat exchanger 3 is communicated with the liquid inlet 12, the heat exchange inlet of the heat exchanger 3 is communicated with the outlet of the methanol filter 2, and the heat exchanger 3 is used for exchanging heat with methanol.
The heat exchanger 3 of the present application is a device for transferring heat from a hot fluid to a cold fluid to meet the prescribed process requirements, and is one application of convective heat transfer and thermal conduction.
In some embodiments, the heat exchanger 3 herein is a plate heat exchanger, methanol flowing inside the plate fins and coolant outside the plate fins.

The basis for adjusting the methanol flow area of the heat exchanger 3 according to the methanol temperature is: when the temperature of the methanol at the detection position is lower than the preset temperature at the detection position, the water flow channel of the heat exchanger 3 is enlarged, the temperature of the heat exchanger 3 is increased, and the methanol is heated rapidly; when the methanol temperature at the detection position is higher than the preset temperature at the detection position, the water flow channel of the heat exchanger 3 is reduced or even closed, and the temperature of the heat exchanger 3 is reduced to ensure that the methanol temperature is within a reasonable range.

In some embodiments, the temperature control module 4 is a thermostat. Specifically, the thermostat is a valve that controls the flow path of the coolant. A thermostat is a thermostat device that generally includes a temperature sensing element that turns on and off the flow of air, gas or liquid by thermal expansion or contraction.
The temperature sensing element of the thermostat herein is used to detect the temperature of the alcohol; the throttle valve of the thermostat is communicated with the liquid inlet 12 and the liquid inlet, the opening of the liquid inlet is regulated, and the flow of the cooling liquid flowing through the heat exchanger 3 is changed by regulating the size of the liquid inlet of the heat exchanger 3, so that the temperature of the heat exchanger 3 is changed.
Further, the inlet of the thermostat communicates with the heat exchange outlet of the heat exchanger 3, and the thermostat has the above-described methanol outlet 41, and the inlet of the thermostat communicates with the methanol outlet 41, thereby forming a flow path of methanol.

The methanol is heated in the heat exchanger 3 by engine circulating water, the circulating water is taken from an engine water outlet pipe, enters the heat exchanger 3 from a liquid inlet 12 and enters an engine water pump water inlet through a liquid outlet.
The circulating water of the heat exchanger 3 comes from the water outlet pipe of the engine, so that the heat generated in the working process of the engine can be utilized, and the energy loss can be reduced.
According to the application, the two parts of the heat exchanger 3 and the methanol filter 2 are integrated, and the water flow of the heat exchanger 3 is adjusted according to the temperature of methanol through the physical thermostat, so that the purpose of heating and controlling the methanol is achieved.
