Real-time monitoring and a response mechanism are combined, the fluid monitoring device, the high-pressure cleaning device and the control device are combined for control, the self-cleaning function of the plate heat exchanger is achieved, and the problems that an existing plate heat exchanger is difficult to clean and low in efficiency are solved.

The embodiment of the invention provides a spray head body device and clothes treatment equipment. The spray head body device comprises a spray head body and an electrolysis assembly. The nozzle body is provided with a water inlet, a water outlet and a flow channel, the flow channel is communicated with the water inlet and the water outlet, the electrolysis assembly comprises a cathode and an anode, and the cathode and the anode are arranged in the flow channel and used for electrolyzing water flowing through the flow channel. According to the embodiment of the invention, the space of the nozzle body can be fully utilized, an additional electrolysis shell does not need to be configured for the electrolysis assembly, and the structure is compact; in addition, the electrolysis assembly does not need to make contact with washing water, batting, hair and other impurities cannot be attached to the electrolysis assembly, and the service life of the electrolysis assembly can be prolonged. In the water injection process, the water flow is large, the electrolysis assembly is strongly scoured by the water flow, and microbubbles are generated on the surface of the electrolysis assembly, so that the scaling phenomenon on the surface of the electrolysis assembly can be effectively improved, and the service life of the electrolysis assembly is prolonged.

The utility model discloses a supergravity centrifugal wet dust removal device for an underground coal mine, which is a purification device for air containing respirable dust, comprises a negative pressure air inlet, an air outlet, a spraying system, a rotary filter cartridge, a pollution discharge box, a power mechanism and the like, and is a device for separating solid-liquid-gas substances. Specifically, dust-containing gas is sucked into a machine body through negative pressure generated by a negative pressure axial flow fan, when the dust passes through a spraying area, the dust is mixed with water mist, the distribution volume of dust particles is reduced, then the dust particles are sucked into a rotary filter cartridge, and the filter cartridge is a filter screen which is of a multi-layer porous structure, facilitates gas passing and has a blocking effect on a solid-liquid mixture; and the rotary filter cartridge is a water-gas separation device and is used for further separating liquid from gas. Through reasonable matching of the negative pressure of the axial flow fan, the resistance of the filter element and the rotating speed of the roller, gas and a solid-liquid mixture can be separated, and emission of purified gas, recycling of purified liquid and collection of solid particles are achieved.

The utility model provides a multifunctional spray gun which comprises a spray gun body, a water outlet switch assembly and a water outlet switching piece. The spray gun body is sequentially provided with a water inlet channel, a mounting cavity, a water passing channel and a water outlet channel, the water outlet switch assembly is arranged in the mounting cavity, and the water inlet channel and the water passing channel are communicated or disconnected through the water outlet switch assembly, so that water outlet and water closing of the spray gun are achieved. The spray gun comprises a spray gun main body and at least two water outlet channels, the water outlet switching piece is movably installed on the spray gun main body, and the water passing channel is communicated with any water outlet channel through the switching action of the water outlet switching piece, so that the water outlet state of the spray gun can be switched, and different requirements of users are met. The spray gun is provided with the multiple water outlet channels and the water outlet switching piece, so that the spray gun has the water outlet switching function, and the requirement of consumers for the water outlet switching function of the spray gun can be met.
