Abstract:
An acid purifier, comprising: a container ( 1 ) for an acid to be purified; a heater ( 2 ); a condenser ( 3 ) including a Peltier semiconductor cooler, a condenser body ( 600 ) and a refrigerant temperature sensor; a purified acid liquid collection bottle ( 4 ) connected with the condenser; a controller; an integrated liquid level control component ( 300 ) for the acid to be purified, connected with the container ( 1 ) for the acid to be purified, and arranged in such a way that a liquid level pipe ( 320 ), a liquid adding funnel ( 310 ) and a waste liquid discharge valve ( 330 ) are integrated; and an acid liquid temperature sensor ( 400, 500 ) arranged in the acid to be purified.

Claim (Index 28):
An acid purifier, comprising:\n a container for an acid to be purified, for containing an acid to be purified; a heater, for heating the container for the acid to be purified, to obtain hot acid steam; a condenser, configured to condense the hot acid steam; a purified acid liquid collection bottle connected with the condenser, for collecting condensed purified acid; a controller, for controlling operation of respective components so as to perform an acid purification process; an acid liquid temperature sensor, arranged in the acid to be purified, for measuring temperature of the acid liquid to be purified; wherein, the controller sets a temperature threshold, receives the temperature measured by the acid liquid temperature sensor, compares the temperature with the temperature threshold, and correspondingly controls the heater, wherein, the acid liquid temperature sensor is a thermocouple-type temperature sensor, two thermocouple leads are placed in a polytetrafluoroethylene (PTFE) capillary, the PTFE capillary is placed in a support tube, the support tube is placed in the container for the acid to be purified, and the PTFE capillary extends to the outside of the container for the acid to be purified through a connection hole on a wall of the container for the acid to be purified, wherein, the lower end of the support tube is connected with a tube coiler, and the PTFE capillary inside the support tube passes through an inner hole of the support tube and gets out, winds around the tube coiler for one circle and enters into the support tube through a hole of the support tube, then extends upward along the support tube, and finally passes through the hole of the support tube and the connection hole on the wall of the container for the acid to be purified, to extend outside the container for the acid to be purified, wherein, a thermocouple head portion is located within the one circle for which the PTFE capillary is wound, and the thermocouple head portion is in contact with the PTFE capillary, the two thermocouple leads are brought into contact oppositely, seemingly as one lead, and the portions in opposite contact form the thermocouple head, wherein, the surface of the thermocouple lead is enveloped by a PTFE envelope layer, and at the position of the thermocouple probe, a thermo-compression method is used for tightly bonding the thermocouple probe to the PTFE envelope layer, wherein, one or more sealing points are present on the thermocouple lead, and a thermo-compression method is used at the sealing point for tightly bonding the thermocouple lead to the PTFE envelope layer.
