Description

In-situ deodorization method for toilet bowl
Technical Field
The invention belongs to the technical field of environmental protection control, and particularly relates to in-situ deodorization and a method for a toilet bowl.
Background
Because of convenient use, the toilet bowl becomes the necessity of most families and many units. During the use of the toilet bowl, the whole toilet space is inevitably filled with odor due to the odor of human excrement. The simple deodorization method is to exchange air through a top exhaust fan or an exhaust fan, and the professional deodorization comprises fresh air deodorization, air circulation deodorization, space reaction deodorization and the like. The essence of the methods is air exchange and deodorization, and the air exchange and deodorization mode usually needs a period of time to be realized, the period is directly related to the ventilation volume of the exhaust air, the number of air exchange cycles is generally specified to be more than 3, the larger the ventilation volume is, the smaller the period is, but the larger the corresponding energy consumption is. In addition, a simple deodorization method is performed by a dilution method (except that the deodorization part is provided with an odor treatment device), namely, odor is directly discharged into the air, and the surrounding air environment is influenced to a certain extent. Whereas professional deodorization requires a more complicated odor purification device. Therefore, the in-situ deodorization technology and method are needed to be developed, so that the odor is reduced to the greatest extent and the air quality in the toilet is affected, and the toilet environment quality is improved.
Disclosure of Invention
The invention aims at the defects and provides the in-situ deodorization and the method for the toilet bowl, which can fully utilize the water in the water tank as the odor absorption liquid and can realize the preliminary treatment of the odor instead of direct emptying.

Furthermore, the pressure which can be borne by the odor collecting ring is negative pressure of-5 kPa, the annular pipeline ring which is made of silica gel or hard plastic pipes and is in the shape of the toilet seat cover is adopted, and the diameter of the annular pipeline ring is 3-5mm larger than that of the inner ring of the toilet seat cover.
Further, the diameter of the annular pipeline of the odor collecting pipe is 10-15 mm.
Further, the odor collecting pipe consists of an inner pipe, an outer pipe and a perforated pipe, and the perforated parts of the inner pipe and the outer pipe respectively account for one third of the inner size of the toilet seat cover.
Furthermore, the perforation aperture of the inner pipe and the outer pipe is 1-2mm, and the distance is 5-10 mm.
Furthermore, the diffusion plate is made of a rubber film or corundum, and the aperture of the diffusion plate for diffusing air is required to be 150-200 microns; the diffuser plate size is based on can putting into toilet bowl water tank bottom, and the quantity of the diffuser plate of adoption is 1 or more than 2.
The toilet bowl in-situ deodorization method adopting the system comprises the following steps of:
1) when a person sits on the closestool, a pressure controller arranged on the lower side of the closestool ring cover detects pressure, and when the pressure reaches over 10kg, the air pump is controlled to be started to begin to suck odor through the odor collecting ring;
2) the odor is directly conveyed into a water tank of the toilet bowl through an air pipe, is diffused through a diffusion plate, and then absorbs hydrogen sulfide, ammonia and other odor substances in the odor by using water in the water tank;
3) when the person leaves the closestool, the pressure controller detects no pressure, the air pump is turned off after the time delay of the time delay controller is delayed for 0.5-2min, the whole system stops working, and the next cycle is waited.
Furthermore, the solubility and the absorption efficiency of the odor substances are improved by adding the alkali slow-release chemical agent into the water tank
Further, the air flow rate of the perforated air openings of the inner pipe and the outer pipe of the odor collecting pipe is 1-3 m/s.
Further, the air pump volume of the air pump is 2-10L/min, wherein the reference volume L of the air pump volume is the effective volume in the toilet, so as to ensure that the circulation is performed for more than 5-10 times within 1-5 min.
The invention has the beneficial effects that:
1. the system and the method provided by the invention are simple and easy to implement, not only can be used for reforming the existing closestool, but also can be used for directly installing the air pipeline, the pressure controller and the like in place in the closestool processing and manufacturing process.
2. The system and the method provided by the invention avoid the phenomenon of temporary odor rush due to the conventional odor diffusion and re-suction treatment, and directly collect the odor from the source. Because the amount of the odor to be sucked is very small, the power of the air pump is far less than that of a common exhaust fan or a fresh air circulating system.
3. The system and the method provided by the invention can fully utilize the water in the water tank as the odor absorption liquid, and can realize the primary treatment of odor instead of direct emptying.
4. According to the invention, the original odor is directly sucked and collected through the in-situ deodorization system, so that the odor is not diffused to the whole space, and meanwhile, the water in the water tank is fully utilized to carry out primary absorption on the odor, so that the air quality in the toilet is greatly improved.
