The invention discloses a method for using a semiconductor heating-cooling device in water-spraying air purification equipment. The semiconductor heating-cooling device is structurally formed by that heat exchange fins are arranged at the lower cold ends and upper hot ends of a same group of P-N-node semiconductor devices (p-n) to form the semiconductor heating-cooling device (W) with refrigerating fins (6) and heating fins (7). The key utilization method, namely structural cohesion requirements in utilization includes: enabling a refrigerating passage formed by a portion, with the refrigerating fins (6), of the semiconductor heating-cooling device (W) to join with a rain area air purification passage (D) formed by a water storage plate (2) and a water receiving plate (5); enabling a heating passage (D-2) formed by a portion, with the heating fins (7), of the semiconductor heating-cooling device (W) to join with an air purification passage (D) with a fan driver (1). By taking the advantage of double effects of the semiconductor devices (p-n) with one side for refrigerating and the other side for heating after electrification, conditions are created for both greatly simplifying heating-cooling facilities (size reduced) and greatly saving energy.

An improved shower head having multiple modes of operation. The shower head may include a first turbine and turbine, each disposed within a unique flow channel. The first and second turbines may interrupt water flow through their respective flow channels, thereby providing at least one pulsating water spray emanating from the shower head. The shower head may include a third flow channel having no turbine disposed therein, such that water flowing through the third flow channel is not interrupted and thus emitted from the shower head as a drenching spray.

A number of water spray holes formed on a water spray plate is not less than 130. A diameter of the respective water spray holes is not less than 0.1 mm and not more than 0.5 mm, and an entire aperture area thereof is not more than 30 mm2. With this arrangement, since the entire aperture area of the water spray holes is reduced, it is possible to achieve water-saving effects. Moreover, since the water spray holes are small and provided by a plurality of numbers, the flow of water sprayed from the respective water spray holes is large to feel some strength hitting the skin and to achieve expansion of shower water so that the sense of using the shower may be satisfied. Moreover, since a plurality of small water spray holes is formed, a larger number of minus ion can be generated.

The invention discloses a water-saving, uneasily blocked and automatic high pressure flush closet, which relates to the field of closets. When no person sits on the closet, a pipeline port is sealed by a closet piston and a stable sealing pipe. When a person uses the closet, tap water enters a water spray elastic rubber pipe; after the person leaves, water stored in the rubber pipe is sprayed out under triple force of restoring force of the rubber pipe and restoring force and transferred tap water pressure of the closet; the water enters a water spray inner shaft pipe from a water tank of the closet; the piston and a cylinder at the pipeline port of the closet move downwards under water pressure, and water is started to be sprayed out from a water spray hole of the cylinder; the water also flows into a pump chamber; a sandwich layer shaft pipe rotates along with an impeller; the water also enters a water spray pipeline of a closet body and an upper part of a water spray outer shaft pipe; and the water spray pipe of the closet and the water spray hole in the closet cylinder are used for rotatablely spraying the water to the inner wall of the pipeline, the water spray hole in the pipeline of the closet body is used for spraying the water to the rotating closet piston, water spray pipe and cylinder. Excrement is fed into a sewer under the action of centrifugal force and sprayed water. The closet finishes flushing.

The invention belongs to the environmental protection technology, and relates to a method for recycling sulfur dioxide in flue gas of a coal-fired boiler, in particular to a method for desulfurization of coal-fired flue gas with a low oxidation rate. Its treatment process and parameters in the desulfurization tower are: a. Cool down and remove dust, spray and wash the flue gas entering the tower with water first, so that the temperature of the flue gas will drop to 40-50°C within 2-3 seconds; b. For the first level of absorption, use the ammonium salt absorption solution with a concentration of 500-650g / l and a pH value of 5.2-6.2 for spray absorption; c. For the second-level absorption, use a concentration of 300-500g / l and a pH value of 5.4 ~6.5% ammonium salt absorption liquid is sprayed and absorbed; d. Washing and defogging the flue gas after absorption treatment, eluting the absorption liquid entrained in the flue gas and emptying it. The invention can reduce the oxidation rate in the ammonia desulfurization process and improve the utilization value of by-products.
